It’s the Dragon Boat Festival again. In this festival, which has infiltrated Chinese traditional culture, there are not only the fragrance of zongye and wormwood, but also the excitement of dragon boat racing and duck catching, and the unique romance of Chinese is hidden.

There are different opinions about the origin of the Dragon Boat Festival, such as commemorating meson push and commemorating Wu Zixu, among which the most popular one is commemorating Qu Yuan. "I’m still good at my heart, although I died nine times, I still have no regrets." This is a patriotic poet’s sincere feelings about home and country.

In ancient times, the Dragon Boat Festival was a festival with evil spirits as the main content. On this day, people inserted calamus, drank realgar, held dragon boat races and sacrificed dragon gods, and prayed for evil spirits with grand and warm ceremonies to welcome the summer.

Zongzi is the standard for the Dragon Boat Festival. Meat Zongzi, egg yolk Zongzi and ice Zongzi … Chinese’s love and persistence in traditional food are also reflected in a variety of Zongzi, which is not unique to the romance on the tip of Chinese’s tongue!

The development history of zongzi

Zongzi was first written as "glutinous rice", which refers to the food wrapped with leaves. Most of the rice used at first was millet.

Millet was planted as early as the Neolithic Age, and it is sticky, also known as yellow millet. It can often be found in the farming sites of old ancestors, and there are also many poems about "plenty of millet in good years" in the Book of Songs.

In the pre-Qin period, zongzi in the north was also called "horn millet", which was made according to the shape of the horn. People wrap millet with leaves to represent cultivated cattle.

The Book of Songs describes the "Good Sacrifice" of Zhou Tianzi after the autumn harvest, in which there is a description of "killing a hen and slapping its horns". Because in the Western Zhou Dynasty, cattle were one of the highest-level sacrifices, which were used to worship the earth gods and the valley gods and to bless the agricultural harvest, and it was impossible to slaughter cattle on a large scale, so "horn millet" became a substitute.

This shows that Zongzi was originally a sacrificial object, which existed long before the birth of the great Chu poet. Perhaps Qu Yuan had eaten Zongzi before his death.

During the Southern and Northern Dynasties, southerners bundled the Dragon Boat Festival and Zongzi with Qu Yuan, and wrapped them into tubular Zongzi with neem leaves and colored silk, which was said to exorcise evil spirits, to pay homage to Qu Yuan, further enriching the cultural connotation of Zongzi.

Qu Yuan, as a model of justice and loyalty, has been worshipped by Chinese people who have been living abroad since the May 4th chaos.

In the Sui and Tang Dynasties, the north and the south were reunited, and the tradition of the Dragon Boat Festival was basically formed. Since then, making zongzi and eating zongzi have become the most representative customs of the Dragon Boat Festival.

Delicious people in the Tang dynasty spent a lot of "kung fu" on studying zongzi. They gradually replaced the millet with glutinous rice, making the taste of zongzi more delicate and soft, no longer just a holiday offering, but also a kind of food. They also invented Jiuzi Zongzi, which is gorgeous in appearance, and "Give Fei Xiang Zongzi" in the famous dinner party in history.

"Give Fei Xiang Zong" is made of glutinous rice mixed with spices extracted from red fragrant flowers. It is eaten on a fashion plate and topped with honey. This thing is particularly expensive, and it is a famous product at the official banquet. Therefore, according to its color, it is called "Give Fei", which is the scarlet (red) given by the emperor to the minister.

It has been verified that the honey-cooled zongzi in Xi ‘an now evolved from the "fragrant zongzi" in the Tang Dynasty. The two methods are similar, but they lack the red spice symbolizing power compared with "giving Fei and containing incense".

Since then, the tradition of making zongzi during the Dragon Boat Festival has been preserved. From the imperial palace to the folk, people not only eat zongzi, but also give it to each other as holiday food.

This tradition has never changed so far. Before and after the Dragon Boat Festival, it is the season to eat zongzi, whether it is wrapped by yourself or given by relatives and friends, and it is always eaten.

The "Sweet and Salty War" of Zongzi

A few years ago, Jiaxing, Zhejiang Province opened the first Zongzi Culture Museum in China to show the origin of Jiaxing Zongzi and the historical context of local time-honored brands.

On the land of China, Jiaxing Zongzi is a school of its own, which is famous for its moderate saltiness and sweetness. Among them, fresh meat Zongzi is the best, and the best pork hind legs and glutinous rice are selected as stuffing, which is oily but not greasy and has a unique flavor.

Jiaxing and Huzhou have been rice-growing areas since ancient times, and the local people are experts in making zongzi, and the food they make is exquisite and delicate. Zhou Zuoren, Lu Xun’s younger brother, a well-known "foodie", wrote: "There are two commonly used words on the dim sum signboard, which I want to borrow and use here. It seems to be appropriate. The north can be called’ official tea food’ and the south is’ Jiahu fine point’ …"

Speaking of North and South Zongzi, I have to mention the "sweet and salty war" that happens every year. The "sweet party" loves the sweet dumplings sweeter than the first love, while the "salty party" only loves the salty dumplings with rich fillings.

The stuffing materials of sweet dumplings are varied, including common bean paste, red dates, candied fruit, etc., as well as roses, osmanthus, kumquat and other flowers and fruits.

Most of the dumplings in Beijing are stuffed with red dates and red bean paste, and a few of them are stuffed with preserved fruit. Suzhou Zongzi is the most representative sweet zongzi in Jiangnan area. Red bean paste, jujube paste and lard are mixed into glutinous rice, and the cooked four-corner zongzi is sweet and delicious.

However, Suzhou people are not only "sweet parties", but also like to eat salty zongzi.

The appearance time of salty rice dumplings is roughly the same as that of sweet rice dumplings. Generally, meat and other ingredients are added, and the taste is salty.

Yuan Mei, a gourmet in Qing Dynasty, was a well-known "salty party". He loved zongzi and invented ham zongzi while writing elegantly. That is, with high-quality glutinous rice, it is first wrapped with bamboo leaves, and then a large piece of fat ham is put in the middle, and then the pot is sealed and simmered. Day and night, the firewood is constantly paid. When the Ruoye was uncovered again, the meat and rice had become one, and the taste was greasy.

Nowadays, most salted zongzi in Jiangsu, Zhejiang and Lingnan are filled with pickled pork, and a few are filled with ingredients such as egg yolk, bacon, barbecued pork and roast chicken.

In addition to the "sweet and salty war", there are many differences in zongye between the north and the south.

Indocalamus, reed, plantain, lotus and even corn leaves, the leaves of all kinds of plants are transformed into "golden green leaves" by virtue of their unique fragrance, which is the only supporting role of "Zongzi Festival" and shows their magical powers in all parts of the country.

The most common zongye in South China is Ruoye. Indocalamus is a shrub-like bamboo plant with large and wide leaves, which mostly grows in southern areas such as Hunan, Jiangxi, Zhejiang and Fujian.

Southerners use bamboo leaves to wrap zongzi. Generally, they first "bake the leaves" to dehydrate them, which is convenient for storage, and they are as green as new, and the aroma is not reduced. In this way, the fragrant leaves become the golden partner of zongzi stuffing.

People in tropical areas find that banana leaves can also be used to make zongzi, which is common among ethnic minorities in Yunnan. Compared with other zongzi leaves, banana leaves are a "big MAC", which often needs to be cut into suitable sizes, and it is difficult to package the classic "triangular zongzi".

In some areas in the north, reed leaves are used as zongzi leaves. Reed is born in rivers and lakes, but its leaves are not flexible, so novices may be exposed when wrapping zongzi with reed leaves.

The meaning of Dragon Boat Festival

Many years after Quyuan threw himself into the river, the Dragon Boat Festival not only became an inseparable CP with Zongzi for thousands of years, but also became a common festival of more than 20 nationalities including Manchu, Mongolian, Miao and Yi, and even went abroad and spread to Japan, Vietnam, Singapore and other Asian countries.

But the Dragon Boat Festival was not just to commemorate Qu Yuan at first.

Dragon Boat Festival is one of the traditional festivals with the most nicknames, also known as Duanwu, Chongwu, Duanyang, Mayday and Tianzhong Festival. The fifth month of the lunar calendar was considered as an "evil month" by the ancients, and the fifth day (that is, the fifth day of May) was even worse, which was taboo for the people and actually had certain scientific basis.

May of the lunar calendar is the season of climate change between spring and summer. There are many droughts in the north, and the rainy season in the south. The climate is hot and humid, and insects and moths flourish, which is easy to infect people with plague. In ancient times when medicine was underdeveloped, people were inevitably frightened.

As a result, the Dragon Boat Festival has also become a festival to collect medicine to get rid of diseases, ward off evil spirits and drive away plague, and it has entrusted the blessings of the ancients to pray for well-being. Except for Zongzi, most of the other Dragon Boat Festival customs have inherited the simple and beautiful wishes of their ancestors.

On the Dragon Boat Festival, in some places, people will hang and wear wormwood. Both wormwood and calamus have the functions of refreshing, inducing resuscitation and repelling mosquitoes. It is rainy and humid in May, and wormwood and calamus strongly volatilize odor, which can just eliminate odor, clean air and prevent bacteria from breeding.

In some places, people drink realgar wine. Realgar, also known as Jiguanshi, is actually a kind of traditional Chinese medicine, which has the efficacy of sterilization, analgesia, disinfection and itching relief when used in moderation, and it is also the secret weapon of the ancients to kill insects and germs.

Even the dragon boat race is related to the evil month to eliminate epidemics and disasters. In some places, dragon boat activities are "sending plague boats". For example, in Guangdong, Hubei and other places in the Qing Dynasty, it was once said that "grass is the dragon and paper is the boat". After carrying the dragon boat through the streets, it was burned to pray for health.

So far, the Dragon Boat Festival customs in Zigui, Hubei, Miluo, Hubei, Huangshi and Suzhou, Jiangsu and other places have been successfully declared as "representative lists of human intangible cultural heritage" by UNESCO.

Although the Dragon Boat Festival in the three provinces and four places has its own characteristics, even the historical celebrities who commemorate it are different, they all give the Dragon Boat Festival a heavier cultural symbol and represent the spiritual totem of the Chinese nation.

Chu people commemorated Qu Yuan on the Dragon Boat Festival, sympathizing with the poets and being loyal to their country. "The whole world is turbid and I am alone, and everyone is drunk and I wake up alone." When Chu was teetering under the threat of Qiang Qin, Qu Yuan threw himself into the Miluo River, taking his own death as the final admonition, awakening the Chu people’s heart of resistance.

The dragon boat race on the water in Hunan is to salvage Qu Yuan. After the salvage failed, people dispersed the fish in the river to prevent them from hurting Qu Yuan’s body and let the poet rest in peace.

The Wu people commemorated Wu Zixu on the Dragon Boat Festival, lamenting that he was suspected by the king after helping the State of Wu dominate. When Wu Zixu was given death by Fu Cha, the king of Wu, he left his last words, saying that he would hang his head in Chengtou and watch the destruction of Wu with his own eyes. Fu Cha was furious when he learned that, and ordered his body to be thrown into the river.

Later generations regarded Wu Zixu as the Tao God. In the Eastern Han Dynasty, Cao E, a filial daughter, cried day and night along the river to save her father who drowned in the Tao. God Xiang Tao prayed, and later she came to the river.

That day, it was May 5th.

The Dragon Boat Festival was originally an "evil day", but it was endowed with awe-inspiring righteousness. Under the oppressive environment of War of Resistance against Japanese Aggression period, the Dragon Boat Festival was reconstructed.

Every Dragon Boat Festival, including Guo Moruo, Wen Yiduo, Lao She and others, most of the literati at that time thought of Qu Yuan, who was grieving and indignant, and pushed the image of Qu Yuan’s martyrdom to the peak of patriotism. Under the special background of the times, it also plays a role in boosting morale.

In the face of the crisis of national subjugation, Professor The National SouthWest Associated University Wen Yiduo shouted: "If we want the festival to exist, we must give it a meaning that our times need."

The Dragon Boat Festival has truly become a festival representing Qu Yuan, symbolizing the orthodoxy, moral sense and sense of justice of China culture.

1905 movie network news At the beginning of this year, a suspense film from India occupied the headlines of various large-scale films, ranking first in the suspense films of airborne watercress — — Andhadhun with a score of 8.7. With the high-energy plot of reversal and brain opening, the film earned nearly $16 million in overseas markets such as India and North America at a low cost of $4.5 million, making it the highest-rated Indian film in 2018. It is reported that this super-high reputation "the best suspense film of the year" has been introduced to China and will be released in the near future.

　

Andhadhun Douban scored 8.7 and won the top spot in IMDb.

The film "Andhadhun" is starring Ayurman, a new movie star, and Tabu, the winner of the Best Actress Award of the Indian Film Audience Award. The story abandons the Indian tradition of the protagonist "Wei Guangzheng" and turns around all the way in a dark and humorous atmosphere. As soon as the film was released overseas, it became a well-deserved "suspense film of the year" with its strong word-of-mouth momentum, which also triggered the high expectations of domestic fans.

There are more than 50 reversal plots in the film, which makes professional fans afraid to blink, and comments to warn the audience "don’t hold your urine before watching"; The ingenious pen at the end also adds a variety of interpretations to the film. After watching the movie, you can "infer what the real story is" by yourself, and it is inevitable to miss any detail. Cheating, killing husbands, destroying bodies, kidnapping, blackmailing and buying and selling organs, the social darkness has become blurred under the black humor of Cohen brothers. Up to now, the film "Andhadhun" has been rated by more than 40,000 people, and the score is currently stable at 8.7. A Douban user said, "Who would have thought that the best suspense film this year was an Indian film?" .

　

"Andhadhun" uses a divine brain hole to interpret black humor

Unlike comedies and special effects blockbusters, which are well recognized by the market, there is only one way for suspense films to stand out — — A super drama that makes the audience "stunned". The suspense, tension and details of the play that can boldly challenge the audience’s IQ are essential for an excellent suspense film. In 2017, the progressive reasoning that was shown in China started with a seemingly old-fashioned case of "Murder in the Chamber of Secrets", but it took 10 minutes at the end to create a shocking reversal, creating the highest box office record for a Spanish film released in China. Similarly, in 2017, the Thai film "Genius in Demand" was wrapped in a youth film, which made a cheating story in the examination room full of suspense.

Small cost, small language, independent production, no big names, in recent years, high-scoring suspense films seem to be such a "birth background." After all, suspense films that can only rely on strong dramas have no shortcuts, which is a "thankless" road for many teams and companies that want to cash in quickly. This year, Andhadhun, which won the title of "the best suspense film", has a solid foundation for drama, and its story was inspired by the French short film of the same name which was a sensation in 2010. This divine short film with Douban score as high as 9.2 took only 14 minutes to create a Piano tuner pretending to be blind and the world he "saw", and after he broke into a murder scene, his suspense and nervousness were raised to the extreme. A gunshot at the end was a stroke of genius, and it became a suspense drama as a textbook.

This time, Indian director Sriram Lagwan made an adaptation of the original short film, keeping the core setting of the original "A Piano tuner pretending to be blind accidentally becomes a witness to a murder". On this basis, the film "Andhadhun" has made many unique and breakthrough expansion. Looking closely at the pilot poster, broken glasses, misplaced keys, spilled coffee, sharp syringes and so on, all play a key role in the film. As many as 50 reversals, each reversal point is like facing "Schrodinger’s cat". You never know what will happen next unless you witness it with your own eyes.

Helping cutting-edge research, supporting technological innovation, and promoting the integration of digital intelligence-

China’s scientific and technological innovation "multiplied"

In today’s era, data has become an important innovation factor. The big model of artificial intelligence, the creation of new materials, biological breeding and basic scientific research are all inseparable from the support of data.

The National Data Bureau and other 17 departments recently issued the "Three-year Action Plan for Data Elements ×" (2024-2026), which clearly launched the "Data Elements× Scientific and Technological Innovation" action, and expounded the data from the aspects of promoting the orderly and open sharing of scientific data, strengthening the construction and scene application of high-quality scientific data resources, supporting frontier research with scientific data, supporting technological innovation with scientific data, supporting large-scale model development with scientific data, and exploring new research paradigms.

From supporting basic research, to helping the development of cutting-edge technologies such as artificial intelligence, and then to promoting the reform of scientific research methods, China’s scientific and technological innovation is multiplying by the "East Wind" of the three-year action plan of "Data Elements ×".

Build "software and hardware"

It is one of the important goals of the "Data Elements × Science and Technology Innovation" action to share the dynamic scientific data in an orderly and open manner, to promote the interconnection of various scientific data generated by major scientific and technological infrastructure and major scientific and technological projects, to support and cultivate the construction of scientific databases with international influence, and to strengthen the construction of high-quality scientific data resources and scene application by relying on platforms such as the National Science Data Center.

Relevant "software and hardware" have been built, and all localities are actively deploying them.

In 2024, Beijing will promote a number of major projects such as computing centers, data training bases and national blockchain hub nodes.

Jiangsu will systematically promote the scale deployment of 5G and Gigabit optical networks, support the construction of Suzhou national Internet backbone direct connection points, and accelerate the layout of computing facilities such as intelligent computing power and edge computing.

Sichuan proposes to moderately advance the construction of digital information infrastructure, speed up the construction of the national hub node of the "east-to-west calculation" project, build the province’s computing power dispatching service platform, and build an integrated computing network development system with computing power, storage power and transportation capacity.

Shandong proposes to deploy high-performance intelligent computing centers, and make overall arrangements for general and vertical large-scale model computing power. More than 25 provincial-level new data centers with a level of 5A have been built, with the proportion of intelligent computing power reaching 30%, and the "Shandong Computing Network" has been built. Support Jining to build Lunan Computing Center. In-depth implementation of the "Double Gigabit" network system project, creating more than 500 typical application projects and opening 40,000 new 5G base stations.

"Hardware" facilities are strengthened, and "software" facilities also need to be upgraded.

"The Internet is a platform for data circulation and convergence, and it is the key to infrastructure in the digital economy era." Mei Hong, an academician of China Academy of Sciences, said that it is necessary to speed up the construction of new infrastructure such as digital networking and data space.

In 2021, China Academy of Sciences released an open and universal platform for storing and publishing scientific data with international service capability-ScienceDB.

The Scientific Data Bank, independently developed by the Computer Network Information Center of Chinese Academy of Sciences, is a paper-related data storage platform, which can provide efficient solutions for the aggregation, management, opening and sharing of paper-related data, and provide a platform and service guarantee for implementing scientific research integrity, cultivating sharing culture, accelerating data circulation and promoting international cooperation.

Scientific researchers can store and publish their collected scientific data in the scientific data bank, and the scientific data bank can concentrate the data resources scattered in individuals and collectives by absorbing "data deposits", "turning small money into big money and turning dead money into living money", making it easier to be discovered, accessed, interoperated and reused. At the same time, before academic papers are submitted, researchers can also upload the paper data to the scientific data bank.

As of February 2 this year, the Scientific Data Bank has collected more than 8.2 million open data sets, with more than 700 million platform visits.

Develop a large model

Developing artificial intelligence model is another important goal of "data elements × scientific and technological innovation".

The "Three-year Action Plan for Data Elements ×" (2024-2026) proposes that the development of large models should be supported by scientific data, and all kinds of scientific data and scientific literature should be deeply excavated. Through fine-grained knowledge extraction and multi-source knowledge fusion, the base of scientific knowledge resources should be built, and high-quality corpora and basic scientific data sets should be built to support the development and training of artificial intelligence large models.

In recent years, China has a good computing power foundation and a broad market in the field of large models, and domestic large models frequently appear and accelerate iteration. According to the data of CCID Research Institute of the Ministry of Industry and Information Technology, there are more than 19 large language model research and development manufacturers in China, among which 15 manufacturers’ model products have been put on record.

With the general abilities of language understanding, logical reasoning, knowledge question-and-answer and text generation, these large language model products are welcomed by users once they are launched.

"Scientific and technological innovation has achieved new breakthroughs. The iFLYTEK Spark Cognitive Model is at the national leading level. " This is a sentence written in this year’s "Government Work Report" of Anhui Province.

IFLYTEK Spark is a new generation cognitive model officially released by Iflytek Company in May, 2023. Since its release, it has experienced many iterations, constantly upgrading the technical base of core competence and continuously empowering all walks of life. At present, iFLYTEK Spark has been affirmed in many evaluations by the National Research Institute of the State Council Development Research Center and the China Enterprise Development Research Center of Xinhua News Agency Research Center, and is known as a high-quality domestic model in China.

"Only by building the big model on a completely autonomous and controllable platform can we firmly grasp the development initiative in the era of general artificial intelligence in our own hands." Liu Cong, president of Iflytek Research Institute, told this reporter. In October, 2023, at the Iflytek Global 1024 Developers Festival, Iflytek announced that it would cooperate with Huawei to build the "Feixing No.1" platform for the domestic large-scale model computing base. On this basis, the iFLYTEK Spark model started a larger-scale training.

At present, iFLYTEK Spark V3.5 based on "Feixing No.1" has completed the training and was released on January 30th. The upgraded iFLYTEK Spark V3.5 has significantly improved its abilities in logical reasoning, language understanding, text generation, mathematical answering, multi-modal and so on. At the same time, iFLYTEK also released the Spark Voice Model and the Open Source Model.

"The big model has brought new opportunities for the development of voice technology." Liu Cong said. Making machines have the ability of learning, reasoning and decision-making is the main task of cognitive model.

"We believe that there may be the following four trends in the development of artificial intelligence models in the future." Liu Cong told this reporter, "The first is multimodal and multilingual. From the perspective of the future development of general artificial intelligence, cognitive intelligence model is the core foundation. Based on this, other data such as voice, image and video can be aligned into a unified semantic space, and multi-modal system presentation can be realized by combining plug-in tools. The second is believable and explainable. This needs to ensure the quality of the source of massive data, the capability of the large model itself and the continuous optimization iteration of the system scheme, plus the escort of regulatory policies and laws and regulations issued by the state. The third is to develop in the direction of systematic innovation. There are precedents of products and applications in the field of AI (Artificial Intelligence) based on the combination of single-point technologies. With the support of large-scale model capabilities, we need to combine a variety of superior technologies to carry out systematic innovation and pay attention to the moat effect it brings. The fourth is the all-localization development of software and hardware. At present, iFLYTEK has invested and deeply participated in the ecological construction of domestic AI chip software, and has made certain gains and progress on the training side and reasoning side.

Promote the integration of numbers and intelligence

Intelligent retrieval, keyword screening, and access to the latest medical information … With the convenient functions brought by big data and artificial intelligence, users can easily experience these services with their fingers. In October, 2023, the standard Yunxiang Station of Taizhou City, Jiangsu Province was officially launched, providing enterprises with genuine, real-time updated and more user-friendly information service support with millions of standard data.

This is an innovative practice of Taizhou to promote the deep integration of digital and intelligent technologies and standards. Throughout Taizhou’s medical and health industry, from online to offline, from "laboratory" to "workshop", the achievements of "intelligent transformation and digital transformation" have moved towards "production line".

Entering the small-volume injection production workshop of Jiangsu Datong Pharmaceutical Co., Ltd. in Taizhou Pharmaceutical High-tech Zone (gaogang district), the automatic production line operates in an orderly manner, and the drug production is efficient, accurate and stable; Through a series of measures such as "replacing machines" and integrated management of information systems, the production plants under Yangzijiang Pharmaceutical Group make the whole process of production more intelligent and digital. Jiangsu Longfengtang Chinese Medicine Co., Ltd. has formed a complete set of modern solutions from pre-treatment to extraction of Chinese herbal medicines, and has created a model of "changing wisdom into several turns" in the field of standardization construction of intelligent manufacturing of Chinese herbal medicines.

The practice in Taizhou shows that at present, data has become an important factor in the medical and health industry, and digital technology has also become a necessary tool for the innovative development of biomedicine. The integration of mathematics and intelligence is indispensable to the innovation and development of the medical and health industry.

In the action of "data elements × scientific and technological innovation", promoting the integration of digital intelligence is also one of the important measures. The "Three-year Action Plan for Data Elements ×" (2024-2026) proposes that scientific data should support technological innovation, focus on biological breeding, new material creation, drug research and development, and accelerate technological innovation and industrial upgrading through the integration of numbers and intelligence.

In recent years, the integration, iteration and diffusion of a new generation of digital intelligence technologies, such as artificial intelligence, blockchain, deep learning, and Internet of Things, have penetrated into R&D, design, manufacturing, customer service and other links, bringing all-round, all-round and full-chain transformation to production technologies and production methods, comprehensively improving the automation, digitalization and intelligence level of the industry, and providing a key driving force for promoting the integration of digital intelligence applications and accelerating the formation of new quality productivity.

Qian Xiaojing, a professor at the School of Economics and Management of Northwest University, believes that data elements, as a new key production factor stored and processed by computer equipment in intangible form in the digital economy era, have the technical and economic characteristics of non-competitiveness, low copying cost, non-exclusiveness and strong externality, and can be reused by different subjects, generating the fusion value of "data+algorithm+computing power" through deconstruction and reorganization, convergence and integration, which provides basic and important resources for consolidating the internal form of digital intelligence integration and accelerating the formation of new quality productivity.

"On the one hand, the organic integration of data elements and traditional production factors has enriched the expression of digital intelligence integration and changed the way of digital intelligence integration from geographical space to digital space." Qian Xiaojing said, "On the other hand, data elements play the role of’ media’ in the reconfiguration and recombination of traditional production factors, resulting in a new factor processing model and a new form of digital intelligence integration."

　　Last year, Beijing ushered in the closing year of the first phase of the national "Atmosphere Ten". What is the effect of five-year atmospheric control? Yesterday morning, the Municipal Environmental Protection Bureau held a press conference to take stock of the air quality improvement and air control measures in 2017 and the past five years.

　　(Reporter Wang Bin) The Beijing Youth Daily reporter learned from the press conference held by the Municipal Environmental Protection Bureau that the average annual concentration of PM2.5 in this city was 58 μ g/m3 last year, which was 20.5% lower than that of the previous year, and the national "Ten Atmospheric Articles" mission goal was achieved. Excellent days increased by 28 days compared with 2016, reaching 226 days; The number of heavy pollution days decreased by 16 days to 23 days. In addition, in the past five years, the average annual concentration of major pollutants in Beijing has dropped significantly, especially sulfur dioxide. In 2017, the average annual concentration of sulfur dioxide dropped to single digits for the first time, only 8 μ g/m3.

　　Last year, the heavy pollution day was only 23 days.

　　According to the relevant person in charge of the Municipal Environmental Protection Bureau, in 2017, the average concentration of PM2.5 in Beijing was 58 μ g/m3, down 20.5% from the previous year; It decreased by 35.6% compared with 2013. In addition, the average annual concentrations of sulfur dioxide, nitrogen dioxide and PM10 were 8 μ g/m3, 46 μ g/m3 and 84 μ g/m3, respectively, which were all improved year-on-year, and decreased by 20.0%, 4.2% and 8.7% respectively compared with 2016.

　　Among the above four main pollutants, the average annual concentration of sulfur dioxide has reached and is far superior to the national standard, but the average annual concentrations of nitrogen dioxide, PM10 and PM2.5 still exceed the national standard. Especially PM2.5, compared with the national standard of 35 μ g/m3, exceeded the standard by 66%. This shows that the improvement of air quality in Beijing will still be a long-term process.

　　In 2017, the number of days with excellent air quality in Beijing was 226, an increase of 28 days over 2016; The heavy pollution day was 23 days, 16 days less than that in 2016.

　　The number of days when air quality reaches the standard will increase by 50 days in five years.

　　Last year, it was the closing year of the first phase of the national "Atmosphere Ten". Compared with 2013, the average annual concentration of major pollutants in Beijing decreased significantly. Sulfur dioxide, the most obvious decline, dropped by 70.4%. Last year, the average annual concentration dropped to single digits for the first time, only 8 micrograms per cubic meter. Followed by PM2.5, with a decrease of 35.6%.

　　According to the relevant person in charge of the Municipal Environmental Protection Bureau, from 2013 to 2017, the number of days of air quality compliance in Beijing increased significantly, with 176 days in 2013 and 226 days in 2017, an increase of 50 days. Among them, the number of first-class excellent days increased from 41 days in 2013 to 66 days in 2017, an increase of 25 days.

　　From 2013 to 2017, the days of heavy air pollution in Beijing were 58, 47, 46, 39 and 23 days respectively, showing the characteristics of decreasing year by year; The number of days of heavy pollution decreased by 35 days in five years, and the incidence of heavy pollution decreased significantly.

　　In the past five years, the concentration of PM2.5 in various regions of Beijing has been decreasing year by year, and the decline is significant. In 2017, the concentration level in each region was significantly lower than that in 2013, and the overall spatial distribution was still characterized by high in the south and low in the north, but the concentration gap between the north and the south decreased.

　　In 2020, the average annual concentration of PM2.5 will drop to 56 micrograms.

　　What is the goal of improving air quality in Beijing in the future? Xiang Li, director of the Atmospheric Environment Management Office of the Municipal Environmental Protection Bureau, said that in the next stage, the Beijing Municipal Association will continue to improve air quality. The new Beijing Urban Master Plan clearly states that under normal meteorological conditions, the average annual concentration of PM2.5 in Beijing will drop to 56 μ g/m3 by 2020, and the atmospheric environmental quality will be fundamentally improved by 2035. "This has actually given a clear plan for the goal and roadmap of atmospheric prevention and control, and the next stage will strive to achieve this goal."

　　The overall improvement of the atmosphere is the result of "human efforts"

　　Controlling air pollution is the result of "people work hard and heaven helps". Liu Baoxian, deputy director of Beijing Environmental Monitoring Center, revealed yesterday that in 2017, the frequency of inversion was low, the air was dry and the frequency of north wind was high. In 2017, Beijing’s air quality improved significantly under the combined effect of continuous air pollution reduction and superimposed favorable atmospheric diffusion conditions.

　　So, how much power did "God help" contribute? Wang Shuxiao, a professor at Tsinghua University Institute of Environment, said that after preliminary assessment, the meteorological conditions have not changed much in the past five years. Take 2017 as an example. Last year, the meteorological conditions were more helpful in the fourth quarter. Cold air activities were frequent and the temperature was low. Four heavy air pollution processes occurred, resulting in five days of heavy pollution, which was significantly lower than the previous two years. However, the meteorological conditions in January and February 2017 were not conducive to the spread of pollution. "So overall, the meteorological conditions in each month of 2017 will be offset. In the case of slightly favorable meteorological conditions, the overall situation is ‘ People work hard ’ The result. However, the impact of meteorological conditions on air quality is complicated, and we are still continuing to evaluate it. " Wang Shuxiao said.

　　Yu Jianhua, chief engineer of Beijing Environmental Protection Bureau, said that the focus of "people’s efforts" is emission reduction, and the role of "God’s help" is diffusion. The intensity of "human efforts" can be quantified, but "God helps" can’t be planned. In any case, people will keep trying.

　　A new round of PM2.5 source analysis is underway.

　　In 2014, Beijing released the source analysis of atmospheric PM2.5 from 2012 to 2013. The main components of PM2.5 in the air are organic matter, nitrate, sulfate, crustal elements and ammonium salts, accounting for 26%, 17%, 16%, 12% and 11% of the mass concentration of PM2.5 respectively. Through model analysis, among the sources of PM2.5 in the whole year, the regional transmission contribution accounts for about 28% to 36%, and the local pollution emission contribution accounts for 64% to 72%. Among the local pollution contributions, motor vehicles, coal burning, industrial production and dust are the main sources.

　　In the past five years, based on this, the city has accurately controlled air pollution through emission reduction measures such as clean energy transformation of coal-fired boilers, loose coal treatment in rural areas, adjustment and withdrawal of enterprises that do not meet the functional orientation and pollution of the capital, and scrapping and transferring old motor vehicles. Practice has proved that the source analysis of PM2.5 is a powerful means to improve air quality.

　　In the past five years, the structure of atmospheric energy has been constantly changing, and pollutants have improved significantly. Correspondingly, the source of PM2.5 has also changed. In the future, will Beijing study and release a new source analysis of PM2.5? Liu Baoxian, deputy director of the Municipal Environmental Monitoring Center, said that a new round of source analysis is also in full swing, and relevant results will be released later.

　　　　In June 2010, Jobs released the classic 4. This generation of iPhone is still three years away from fingerprint recognition, and only three months later, Apple acquired a Swedish company called Polar Rose, which is a small company with only 15 people. Is it anything else that Apple is interested in? It is Polar Rose’s unique face recognition technology. That’s right, this is the predecessor of the Face ID that was carried on the internet seven years later.

Seven years of hard work, iPhone X facial recognition, past lives

　　　　　It is hard to imagine that in 2010, before fingerprint recognition was born, Apple began to lay out 3D vision, and after 7 years of dormancy, it first appeared in the form of facial recognition. So when there is talk that Face ID is just a substitute for the iPhone to solve the fingerprint on the screen in a hurry, we have to admit that we underestimate the Apple Empire.

　　　　Polar Rose’s main technology is to use artificial intelligence to engage in image and video analysis and extract three-dimensional information from two-dimensional images, but Apple’s layout in 3D vision is still one step behind Microsoft’s. Because as early as the E3 exhibition in June 2009, Microsoft officially released Kinect, a somatosensory game device, which changed the way people interact with games. We can play games by shaking our bodies (Nintendo’s Wii still needed a remote control stick).

Kinect somatosensory game (picture quoted from gamefy)

　　　　　And even the key here is the depth camera, which is used to capture human body movements and then hand them over to the program to identify, remember, analyze and process these movements. This technology is called PrimeSense by a company.Provided by the company.　　　

　　　　　　PrimeSense is an Israeli company founded in 2005, and developed a 3D sensor in 2006. Its founders all have strong scientific research background. At that time, the game industry had been stagnant, and they have been thinking about how to make changes, such as letting people pick up the sword in the game instead of the remote control handle. Finally,PrimeSense locked the camera.

Kinect(Image quoted from cnblogs)

　　　　　At the game developers’ conference that year,PrimeSense showed the prospect of 3D sensors in the game field, and was recognized by Microsoft, which gave birth to the later.Kinect。

3D recognition of the originator’s structural light to achieve PrimeSense

　　　　PrimeSense3D recognition technology is mainly a kind of structured light--—Light Coding (optical coding technology), we know that the camera wants to capture human movements, and it needs to be realized by judging the depth of field. Structured light is to structure light, and its principle is to use a projector to project a grating or a linear light source onto the measured object, forming a distorted shape on the surface of the measured object, such as the bar grating in the picture below, which projects irregular lines on the surface of the fish.

Principle of structured light technology

　　　　Such a distorted image is captured by a camera in another position, and the lines seen from its angle are obtained. When the positions of the projector and the camera are fixed, the distortion degree of the lines captured by it is also consistent, so that the distorted two-dimensional image can restore the three-dimensional imaging of the object surface. Here, the principle of optical triangulation is mainly used.

Principle of structured light technology

Principle of structured light technology

　　　　The Light Coding used by PrimeSense is somewhat different. It will emit a light source called "laser speckle" in space. This light source is characterized by high randomness, and different patterns will appear with different distances, so that the speckles in different spaces are the same. After the light source is emitted, it is equivalent to that the whole space has been marked. When an object is placed in this space, the spatial position of the object can be monitored through the change of speckle.

　　　　　PrimeSense will record a speckle pattern on the reference plane at intervals in space to form a three-dimensional speckle pattern group. When someone enters the space, it will record it again to form a contrast and correlation operation, and then a three-dimensional image of the whole scene can be obtained. This principle is used by Microsoft’s first generation Kinect depth-of-field image.

　　　　Since 2009, technology companies have discovered that 3D vision is a huge treasure that has not yet been tapped, including Microsoft, Intel, Google, Samsung and other companies that have invested in the development of 3D vision through acquisitions and independent research and development. In 2009 and 2010, Microsoft acquired 3D-TOF camera companies canesta and 3dv. In 2013, Intel launched RealSense technology and Google launched Tango project.

　　　　At this point, we haven’t seen much of Apple’s shadow, but since Microsoft announced its parting ways with PrimeSense, Apple has just appeared.

Microsoft’s self-developed TOF Apple Leaks Achievement Face ID

　　　　　In 2013, a new generation of Kinect came out. Instead of continuing to use PrimeSense, it chose to independently develop 3D sensors. In fact, the second generation of Kinect adopts a 3D vision technology-TOF, which is completely different from PrimeSense structured light. These technologies are accumulated from the previously acquired companies canesta and 3dv, which hold the patent of TOF camera. Previously, it was always thought that the first generation of Kinect used TOF technology.

TOF 3D vision (picture quoted from China Electronic Network)

　　　　TOF is short for Time of flight. It is to send light pulses to the target continuously, and then receive the light from the object with a sensor. By detecting the flight (round-trip) time of the light pulses, the distance between the target and the object can be obtained. Usually, the LED emits infrared rays, the imaging sensor receives infrared rays reflected from the surface of the object, and the device emits a sinusoidal signal whose intensity changes with time period, and the depth is calculated by obtaining the phase difference between the transmitted and received signals.

TOF technology principle

　　　　　In addition to structured light and TOF technology, there is also a binocular stereo imaging technology, but it will not be introduced here because the technology is immature.

　　　　　Both structured light and TOF technology have their own advantages in 3D vision. For example, structured light has mature technology, low power consumption and high resolution of plane information, but it is easily affected by illumination, and its performance in strong light is not very good, and its recognition distance is close, but its cost is high. TOF scheme has good anti-interference and long recognition distance, but it has low plane resolution, high power consumption and medium material cost.

Comparison of three 3D vision technologies (picture quoted from Haitong Electronics Research)

　　　　In any case, Microsoft gave up using structured light technology.PrimeSense，Although PrimeSense was somewhat disappointed, it didn’t stop the pace of research and development, and decided to reinvent itself, and developed a very small 3D sensor in the world.CApri and Capri have three times the depth resolution and 50 times the light resistance (enabling them to work in sunlight), but their bodies are reduced by 10 times.

　　　　Maybe it isPrimeSense’s efforts in product miniaturization have enabled 3D sensors to be used in notebooks, tablets and even computers, and also allowed Apple to see its potential. Microsoft is right.The abandonment of PrimeSense finally made Apple miss it..

　　　　　So, finally, in September 2013, Apple officially made its debut and spent $360 million to acquire PrimeSense, which enabled this ambitious company to master the core 3D vision technology.

Those invisible ones behind Face ID are bought in buy buy.

　　　　　Apple’s acquisition of PrimeSense is still advancing the miniaturization of 3D sensors, and increasing investment and patent layout. In April 2015, Apple submitted a patent application for 3D gesture control technology; In July 2015, Apple submitted a facial recognition patent named "Low Threshold Facial Recognition". In March 2017, Apple released a new patent for 3D vision-face recognition using depth of field information, and a complete patent map of face recognition gradually became clear.

　　　　　Then there is a series of crazy acquisitions:

　　　　　In April 2015, Apple acquired LinX Imaging.

　　　　　　　　　　LinX Imaging mainly develops multi-hole cameras for mobile devices, which can reduce the height of the camera and make the camera no longer protrude. Another black technology is to use porous design to accurately measure the difference between pixels in different images, so as to create a depth-of-field image, which allows us to scan the object in three dimensions only by taking pictures.

LinX Imaging 3D scanning technology

　　　　　In November 2015, Apple acquired Faceshift.

　　　　　Faceshift is a motion capture company, which developed the technology of tracking facial expressions in real time and then using animation. This technology was used in Star Wars movies to make the expressions of animated characters imitate the expressions of actors more accurately. In the field of games, users can use avatars that are updated in real time according to their own expressions.　　　

Faceshift expression capture

　　　　　It turned out later that,Faceshift is not only used asIn addition to face recognition, it is also used by Apple in Animoji.

　　　　　In January 2016, Apple acquired Emotient.

　　　　Emotient is a company dedicated to judging people’s emotions through facial expression analysis. This technology will grab people’s faces and then use recognition technology to identify facial expressions.

Perceive facial emotions

　　　　In February 2017, Apple acquired RealFace.

　　　　　RealFace is good at facial recognition. The company has developed a unique facial recognition technology, which integrates artificial intelligence and brings human perception back to the digital process.

RealFace face recognition

　　　　　　　　The large-scale acquisition enabled Apple to quickly master the core technology of 3D vision, especially in the field of face recognition, and also prevented competitors from catching up with Apple quickly through acquisition, so at the new product launch conference in the fall of 2017, X with Face ID function made a stunning debut.

IPhone X facial recognition

The real essence: a quick glance

　　　　　According to Apple’s perfectionist product design concept, X’s "Liu Haier" should not exist, but Jonathan Ive is still willing to make way for "small space", because he also knows that it is not just a full screen on the front that really builds Apple’s next decade, but more importantly, the stunning "that light glance".

　　　　"All along, we have an idea, looking forward to creating such an iPhone: it has a full screen, which allows you to completely immerse yourself in it when using it, as if forgetting its existence. It is so smart, your touch, touch, word, word, even a glance, will get its heart-felt response. And this idea has finally become a reality with the arrival of iPhone X. Now, just meet the future. "

Little space

　　　　Looking back, "Small Space" is highly integrated with Apple’s research results in face recognition, in which the dot matrix projector will project more than 30,000 invisible light spots and analyze them to draw accurate and detailed depth maps for our faces. The infrared lens will read the lattice pattern, capture its infrared image, and then send the data to the security compartment in A11 Bionics chip to confirm whether it matches, using the structured light technology of PrimeSense. In addition, Apple can recognize your face even in the dark through the floodlight sensor and invisible infrared light.

　　　　　Apple chosePrimeSense’s structured light, rather than TOF, pays more attention to the proper recognition distance and high resolution of structured light. Compared with TOF, the lower power consumption also makes structured light more suitable for mobile platforms. However, structured light has a natural disadvantage in strong light. I don’t know if iPhone X can still perform well in the big sun.

　　　　　It is worth mentioning that Face ID is only a part of the energy released by Apple’s accumulated 3D vision for 7 years. In addition to unlocking the face on iPhone X, it also creates a series of functions that seem to show muscles but are very interesting, such as "moving expressions".

　　　　Through the complex system of the original deep camera, iPhone X can analyze more than 50 different facial muscle movements to detect facial 3D contours. On this basis, the "dynamic expression" is derived, that is, the user’s face is captured in 3D modeling. The special effects we often see in movies belong to this category, but this time we can achieve them through mobile phones.

Verbal expression

　　　　Combined with A11 bionic deep learning, Face ID also has the ability of deep learning. It has a special neuron engine, which can use machine learning technology to identify the changes of your appearance. Recently, the white paper on Face ID disclosed by Apple revealed that if your face changes greatly, such as shaving, Face ID will confirm the facial changes through password input and automatically record them in the database, instead of letting you re-enter your face.

Face ID, a small test, Apple’s 3D big move is AR.

　　　　Through patents, we can see that Apple has also reserved a series of 3D gesture operation technologies. Today, when the somatosensory operation has been tepid, we are very happy to see that the future somatosensory operation still needs Apple, a "latecomer", to subvert, and this is the real use of 3D vision.　　　　　

　　　　The 3D gesture operation may be realized on the Mac platform, and the Face ID on the mobile platform is just a small test of 3D vision. Apple said that AR will be an indispensable link in the future, and the energy exerted by the rear dual camera to join 3D vision can not be underestimated.

　AR game

　　　　　At present, Apple has released ARKit development platform, and it has become a huge AR development platform in one fell swoop. However, the AR experience of X is still based on traditional cameras, which is far from 3D cameras. Therefore, when Cook enthusiastically introduced the AR function of iPhone at the press conference, he not only gave the expectation for the next decade, but also had already targeted your wallet for the next decade.

　　Bananas have different maturity and different health effects on human body. The Japanese beauty and health network "Beauty Ranger" introduced this.

　　Green banana loses weight.Professor Yo Kato Zhi of Hirosaki University found that immature green banana is rich in "indigestible starch" and its glycemic index is lower. In other words, the greener the banana, the lower the calorie intake, which is more beneficial to weight control.

　　Yellow banana beauty.People who want to beautify their skin are recommended to eat bananas with yellow skin. Bananas of this color are ripe and contain more vitamin B2 and vitamin B6, which has a good effect on preventing and treating skin problems. Professor Okubo Yiliang of Tohoku University found that yellow banana has a strong antioxidant effect, which can effectively remove free radicals from the human body, thus achieving a cosmetic effect.

　　Bananas with brown skin help digestion.Ripe bananas often have black spots or brownish skin. Studies show that this kind of brown banana contains phospholipids that are rare in fruits and has the effect of inhibiting gastric ulcer. Therefore, people who usually have a bad appetite may wish to eat brown bananas to help digestion. ▲ (Life Times special correspondent Yao Lijie)

　　Xinhua News Agency, Washington, January 21st(International observation) The candidates for Biden’s government team are meaningful.

　　Xinhua News Agency reporter Sun Ding Xu Jianmei Deng Xianlai

　　After US President Joe Biden officially took office on the 20th, he has introduced a number of administrative measures, including the return of the United States to the Paris Agreement on climate change. The Senate controlled by his Democratic Party is also actively promoting the confirmation process required for relevant cabinet members before taking office.

　　The United States, which Biden inherited, is deeply mired in multiple crises: there are more than 400,000 deaths in COVID-19, unprecedented political tears, weak economic employment and high debt risk. In this context, it is particularly important for the president to be in power. Some analysts pointed out that the main features of Biden’s cabinet nomination are the activation of "Washington Old Man" in order to ensure the rapid operation of the government, the diversification of personnel background in order to achieve political unity, and the reward for running for "hero".

　　Who is in love?

　　In addition to the vice president, the US cabinet also includes 15 heads of administrative departments, including the Secretary of State, the Minister of Finance, the Minister of Defense and the Minister of Justice. In addition, the White House Chief of Staff, Assistant to the President for National Security Affairs, Director of National Intelligence, US Trade Representative and other important positions have cabinet level. Biden completed the nomination or direct appointment of all cabinet and cabinet-level officials before taking office, and the Senate is now beginning to review and vote on the nominees who need to be approved by him. On the 20th, the Senate approved Averil Haynes as the Director of National Intelligence, the first cabinet-level official in Biden’s administration confirmed by the Senate.

　　Biden’s important cabinet nominations include: former Deputy Secretary of State Anthony Blinken as Secretary of State, former Federal Reserve Chairman janet yellen as Treasury Secretary, retired four-star general lloyd austin as Defense Secretary, and Chief Justice merrick Garland as Attorney General. These four positions are traditionally called the "four big members" of the cabinet and have higher importance and exposure.

　　Among several cabinet-level positions concerned by the outside world, Biden appointed Ron Klein, who had served as his campaign adviser, as the White House chief of staff; Jack sullivan, the vice president’s national security adviser when he was the vice president of the Obama administration, was appointed as the president’s national security assistant; Nominated Qi Dai, chief trade adviser of the House of Representatives Ways and Means Committee, as the US trade representative.

　　In addition, Biden also made some "addition and subtraction" for cabinet-level positions. For example, he established the post of presidential special envoy on climate issues and appointed former Secretary of State John Kerry as the post, and re-promoted the permanent representative of the United States to the United Nations to the cabinet level, but the director of the Central Intelligence Agency no longer held the cabinet level.

　　Quite purposeful

　　Some analysts pointed out that many of Biden’s cabinet members were senior officials during the administration of former President Obama, and some even served as the top or second-in-command of federal government agencies. The editorial of USA Today said that many of Biden’s cabinet members are "old rivers and lakes" in Washington. They have rich policy experience and are familiar with the operation of the federal government. The United States is now facing multiple problems, and federal government agencies need these "skilled hands" to take over to bring more stability.

　　At the same time, it is noteworthy that Biden’s cabinet candidates also paid attention to balancing gender, race and other factors, and did not forget to support the younger generation and reward the "heroes" in the election. If all the candidates are successfully approved by the Senate, a series of firsts will be created: the first aboriginal cabinet minister, the first female finance minister, the first African-American defense minister, the first Hispanic health and human services minister, the first immigrant-born homeland security minister, and the first Asian-American trade representative. It is worth mentioning that Kamala Harris has made history as the first female vice president of the United States.

　　Biden also nominated Pete Buttigieg, former mayor of South Bend, Indiana and former Democratic presidential candidate, as the transportation secretary. American media believe that 39-year-old Buttigieg is one of the new political stars of the Democratic Party, and it is only a matter of time before he runs for the presidency again. Biden intends to help him "brush up his resume".

　　In addition, almost all the "heroes" of Biden’s campaign team were entrusted with important positions, which is also the usual practice for the new president to select and employ people.

　　Face obstacles

　　At present, the Democratic Party and the Republican Party each hold 50 seats in the Senate, and the Vice President, as the Speaker of the Senate, holds the decisive vote. This means that, not surprisingly, Biden’s cabinet nomination will be passed more smoothly in the Senate.

　　However, some analysts pointed out that the situation is slightly complicated. At present, the Senate should not only begin to hear the impeachment case against former President Trump after he leaves office, but also consider a new round of economic aid plan for the COVID-19 epidemic. These time-consuming and labor-intensive agendas may affect the progress of the Senate’s deliberation and approval of cabinet nominations.

　　The US "Political News" published an article saying that considering the partisan disputes caused by the impeachment case, it is not easy for Biden’s cabinet candidates to get approval quickly. Biden expressed concern about this and called on the Senate to "work in parallel", with half a day being devoted to hearing impeachment cases, and the other half being devoted to reviewing and approving cabinet members and promoting a new round of economic aid plan for the COVID-19 epidemic.

　　At present, Biden has appointed a series of acting officials to temporarily take charge of important federal government agencies until the Senate approves the official candidates, so as to try to ensure the normal operation of government departments during the transition period.
