On special New Year’s Eve, angels in white held his ground.

Seven medical staff on duty are eating "imprint" New Year’s Eve correspondent Yan Lingling for the picture.

Blessing cake sent by enthusiastic friends

  On New Year’s Eve, family reunion, having a reunion dinner, saying goodbye to the old year and welcoming the new year are the customs written into China people’s genes.

  However, on this special New Year’s Eve, about 80,000 medical staff in Wuhan are still sticking to their posts, leaving behind the figure of "the most beautiful retrograde". Encourage each other to welcome the new year with patients with new pneumonia, and send the fruit cake that was sent by enthusiastic friends to the family online for the New Year … … Give up reunion with relatives, only because of a common desire — —

  Stick to the battlefield and give more people the strength to overcome the epidemic.

  "I hope to win this war as soon as possible!"

  Medical staff of Jinyintan Hospital spend New Year’s Eve with patients.

  On New Year’s Eve, Changjiang Daily reporter made layers of protection and entered the isolation ward of Jinyintan Hospital in Wuhan, and visited doctors, nurses and patients with new pneumonia on the spot for New Year’s Eve.

  At 11: 30, nurse Yang Anli came to the front door of the new pneumonia isolation ward with Spring Festival couplets and lanterns, put the couplets on the door and hung the red lanterns. Yang Anli is a provincial model worker. In 2003, she went to Beijing to fight SARS on behalf of Jinyintan Hospital.

  There are more than 30 patients with new pneumonia diagnosed in the South Third District, and the hospital has prepared an apple for each of them. After the protection, nurse Le Yanling made a victory gesture to the reporter, carried the apples into the ward, and distributed the apples to the patients one by one.

  At 1 o’clock in the afternoon, the reporter came to Nansi District. Four nurses put on protective clothing and sent the hot jiaozi to the ward, giving each patient a copy.

  The reporter learned that Jinyintan Hospital is the earliest "four centralized" hospital in our city to deal with the new pneumonia epidemic. The hospital went to work as usual during the Spring Festival. In the first line of the decisive battle against the epidemic, more than 460 medical staff were on duty every day.

  Dr. Han Yuan missed the group year video.

  Cake fruit sent from all over the country is "New Year’s Eve".

  "Professor Wang, come and have dinner!" At 5: 20 pm on January 24th, Professor Bing Wang, who rushed to Wuhan from Jingzhou Central Hospital, returned to the department. Cakes and fruits sent from all over the country became his "New Year’s Eve" this year.

  On the morning of 24th, Bing Wang got into intense work, and got off work at 12 noon. In the afternoon, he voluntarily gave up his rest for fear of the unstable condition of his seven patients, and missed the "video" of his family reunion in Jingzhou.

  "In the year of the 3 o’clock group at home, I didn’t receive a video call, and my family sent me a picture." Bing Wang said that his family’s annual meal was very rich, but his annual meal was not bad, which was very special.

  "How about cakes, fruits and dumplings? Not bad!" Bing Wang pointed to boxes of food on the table and said that these were sent by enthusiastic friends from all over the country. The first time I spent the New Year alone in a foreign country, I ate such an annual meal for the first time, but I was able to reunite with the medical staff who fought side by side. Bing Wang felt very warm. "I will finish my work later and video with my family."

  The "video dinner" family of three told each other to be 9 years old and asked their parents to pay attention to safety.

  "Mom, I’m eating New Year’s Eve." "Eating New Year’s Eve, did you say a blessing to your grandparents?" … … At 6: 50 pm on January 24th, Yang Qian returned home after a day’s frontline battle against new pneumonia, and she and her husband Liu Xinghua got through a video call with her son who was in Huangzhou for the New Year.

  Liu Xinghua is a radiologist in Wuhan No.1 Hospital, who is responsible for taking CT images of patients. Yang Qian is a radiologist, who is responsible for registering patients at the window. He needs to contact a large number of patients with fever every day. Because my grandparents in Huangzhou always talk about their grandchildren on the phone, the couple sent their children to Huangzhou as soon as the winter vacation was over on January 6.

  "I didn’t expect that after returning to Han, the number of fever patients increased day by day. We were often busy late at night to go home, and sometimes it took several days to call our son." Liu Xinghua said that his son pays attention to the news of new pneumonia on TV every day and reminds them to pay attention to safety every time he calls.

  Take off the protective mask from the intensive care unit and eat the "imprint" reunion dinner.

  On January 24th, at 12: 20, the first wave of "reunion dinner" was served at a small table outside the intensive care unit (NCU) of the First Hospital of Wuhan. Seven medical staff on duty just took off their protective masks, leaving a deep impression on their faces. The annual dinner on the table is a box lunch provided by the hospital, with a banana and a box of yogurt for each person.

  At this time, 15 critically ill patients were admitted to NCU, including one suspected new pneumonia patient who received isolation treatment. On the same day, there were 15 medical staff, including Shan Ping, director of the ward, and Sun Chun, head nurse. In the afternoon, the medical staff transferred the suspected patients with new pneumonia to the designated hospital for treatment.

  The nurse fought for more than 20 days and didn’t go home. The family had a new year’s meal across the screen.

  On New Year’s Eve, Feng Qiong, the head nurse of the first ward of the Department of Respiratory and Critical Care Medicine of Wuhan Sixth Hospital, who has been stationed in the hospital for more than 20 days and has not returned home, still sticks to the front line. "Don’t worry about family matters, it’s all up to me!" At 7 o’clock in the evening, Feng Qiong, who had just finished her work, ate the New Year’s Eve dinner sent by her husband, while taking advantage of this rare gap, she connected with her relatives at home by video phone, and a family of four had a different kind of annual meal through their mobile phones. Feng Qiong, who has been engaged in nursing for 25 years, has successfully completed the medical treatment of flood fighting in 1998, SARS in 2003 and Wenchuan earthquake in 2008. This time, in the fight against the new type of pneumonia, she is still in the forefront, leading a group of "white warriors" in the department to the front line.

The amount involved is 53 million! Spanish prosecutors sued Barcelona for bribing referees.

According to the Spanish newspaper El Paí s reported on the 11th, on Friday, local time, Spanish prosecutors formally sued Barcelona La Liga for sports fraud and commercial corruption, involving 7.3 million euros (about 53 million yuan).

The accused included two former club presidents, Sandro Rosell and Josep Bartomeu, who were suspected of bribing former Spanish Football Association officials to gain partiality in the match.

After learning this news, Barcelona’s arch-rival Real Madrid Club immediately announced that it would hold an emergency board meeting to decide how to respond to the incident.

Laporta, current president of Barcelona.

In February this year, many Spanish media reported that Barcelona was in big trouble, and Spanish prosecutors were investigating its commercial corruption and violation of fair competition.

Sure enough, on Friday, local time, Spanish prosecutors formally sued Barcelona, accusing the latter of colluding with Jose Negreira, former vice chairman of the Spanish Football Association’s referee technical committee, involving a total amount of 7.3 million euros.

The referees’ technical committee is usually responsible for assigning referees for various competitions of the football association, selecting which referees will enforce the law in which post, and selecting referees to participate in international competitions.

According to the prosecution’s report, based on an oral secret agreement, two former presidents of Barcelona, Rosell and Bartomeu, remitted about 7.3 million euros to the consulting company owned by grella from 2001 to 2018, in order to seek "favoritism" in the penalty and result of the competition.

Rosell, Bartomeu and two other former Barcelona executives were charged with commercial corruption, unfair management (using partners’ money for illegal purposes) and forging business documents. Once convicted, they will go to jail.

It is worth noting that laporta, the current president of Barcelona, has not been charged. He served as the president of Barcelona from 2003 to 2010, but denied any illegal acts.

Team coach Harvey revealed in an interview that he had already communicated with laporta. "This is the responsibility of the management. He told me not to worry, we just need to focus on football."

Spain’s El Pais pointed out that this investigation originated from a tax inspection, and Negreira told the Spanish tax authorities that Barcelona paid the money in order to have a "neutral" penalty in the competition.

He also said in an interview with Spain’s radio Searle that he would never be partial to Barcelona when assigning referees. His job is just to help the club as a consultant and tell them how players should behave in the face of various referees.

Previously, Barcelona officials had a similar statement, saying that the club only paid an "external consultant" who provided them with "technical reports related to professional referees" and called it "a common practice of professional football clubs".

However, the Spanish prosecutor still considers the amount of 7.3 million euros suspicious because it is nowhere to be found in the club’s articles of association and has not been approved by the shareholders’ meeting.

The Associated Press (AP) analysis believes that it is indeed a routine operation in international football to obtain referee technical reports, and clubs can purchase or prepare relevant information from external companies.However, it is not a routine operation to provide large sums of money to insiders of Spanish referee law enforcement agencies to obtain reports.

Up to now, Barcelona Club has not issued the latest statement on this matter. However, an anonymous club executive told Reuters that the club had "anticipated" the accusation. "This is only the preliminary investigation and hypothesis of the prosecution, and the judicial investigation has just begun. The club will fully cooperate, but we have never bought any referee and never tried to influence the decision of any Football Association official. "

In response to the corruption scandal in Barcelona, the first to take action was its arch-enemy Real Madrid Club. The latter announced on the 11th that the board of directors will be held on March 12th local time.

Real Madrid fan magazine "Madridista Real" reported that the board of directors of Real Madrid may choose to "sever relations" with Barcelona Club, and may even decide to appear as a private prosecutor in future court trials.

What is the Internet of Things AIoT?

AIoT intelligent internet of things is artificial intelligence internet of things. AIoT is the abbreviation of AI Artificial Intelligence and IoT Internet of Things. It is an artificial intelligence Internet of Things that collects a large amount of data from different dimensions through the Internet of Things and stores it in the cloud. Based on big data analysis and AI and other technologies, it realizes the digitalization and intelligence of everything. Artificial intelligence is a subject that studies how computers can simulate people’s thinking processes and intelligent behaviors. It is based on bionics, the improvement of algorithm model and calculation speed, and the commonality between human neurons and computer doors (doors are the basic unit of computers). Its strength lies in its learning, reasoning, thinking, planning and other abilities, which ordinary intelligent machines can’t do.

The embedded Internet of Things needs to learn a lot, so don’t learn the wrong route and content, which will lead to a salary failure!

Share a data package for free, almost over 150g. The learning content, face classics and projects are relatively new and complete! It is estimated that it will cost at least dozens to buy some fish.

The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected and interacted through various devices and technologies such as information sensors, radio frequency identification technology, global positioning system, infrared sensors, laser scanners, etc., and the collection of all kinds of required information such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., and the realization of ubiquitous connection, identification and management between things and people through various types of network access. Through this definition, we can feel that this will be a huge database, and the learning process of artificial intelligence also needs a lot of data information. Obviously, this is a link between artificial intelligence and the Internet of Things, which can link them together and play a greater role.

In short, the Internet of Things (IoT) uses terminals with different protocols to carry out information interaction and intelligent processing through a certain agreed protocol, while artificial intelligence can keep learning and become more and more intelligent with data. If artificial intelligence is software, it needs the Internet of Things as a carrier, and if it is hardware, it needs artificial intelligence to drive it. Therefore, we can also regard the Internet of Things as a carrier of artificial intelligence.

The Internet of Things is an important part of the new generation of information technology. The English name is "The Internet of things". Therefore, as the name implies, "the Internet of Things is the Internet of Things". This has two meanings. First, the core and foundation of the Internet of Things is still the Internet, which is the expansion and expansion network based on the Internet. Secondly, its clients expand and expand between any goods, and exchange and communicate information.
