Daughter suffers from uremia several times. Father donates kidney to save daughter: I am willing!

  "Son, dad can give you a kidney, so you don’t need dialysis, and you can live a normal life."

  "No, Dad, I can’t have your kidney. I don’t want you to suffer."

  "The doctor said, as long as you pay more attention, my body is no problem. You have a long way to go, and Dad hopes you can live a normal life. " Dai Junfu, who rented Dujiangyan, tried to persuade him, but he could only say these words. He felt that the words were very pale, but all his thoughts were in his heart. It’s just that my daughter with uremia is also very determined and doesn’t want to drag her father down.

  If it is deadlocked for three years … …

  Finally, on April 2 this year, Dai Junfu reached his wish to donate his kidney to save his daughter. The left kidney he donated was transplanted to his 21-year-old daughter Dai Rui. Prior to this, Dai Rui had been repeatedly notified of critical illness.

  "I can save my daughter with a kidney, I am willing!" At the age of 23, Dai Junfu became a father. At the age of 45, he gave his daughter another life.

   Kidney donation deadlock

  I persuaded my daughter to accept her kidney for three years.

  After kidney transplantation on April 2, Dai Junfu returned home to recuperate, and his wife Zhou Liqun has been taking care of her daughter Dai Rui in the hospital. Their home is a two-bedroom apartment located in Zhongxing Town, Dujiangyan City. There are no tiles on the clear water floor. Although it is a rented house, it is also a warm home for three people.

  From the age of 13, my daughter Dai Rui has been ill for 8 years. In the past few years, this family has a regular operation schedule: every Monday, Wednesday and Friday, her daughter Dai Rui rides a battery car to Dujiangyan Red Cross Hospital for dialysis; Dai Junfu works in the front of Qingcheng Mountain Scenic Area, which is the main source of income for the whole family. Zhou Liqun suffers from Sjogren’s syndrome (immune disease) and usually does odd jobs in the local area to supplement her family.

  "My daughter’s illness, because of dialysis and review, did not study." Dai Junfu is sitting on the sofa, and he needs a cushion when he is still recovering from surgery. He said that before his daughter got sick, a family of three had the most ordinary happiness. On weekends, I will also go to the river for tea or visit the park.

  In 2010, Dai Rui was diagnosed with systemic lupus erythematosus. Dai Junfu looked around for remedies for this. He was cheated of thousands of money, but his condition did not improve. He finally realized that he had to be treated honestly in the hospital.

  In 2013, Dai Rui’s condition deteriorated into uremia. After talking to the doctor, Dai Junfu was very blocked and didn’t know how to speak.

  "Son, dad can give you a kidney, so you don’t need dialysis, and you can live a normal life." Knowing that kidney transplantation is the best choice for her daughter, Dai Junfu still made a bottom with Dai Rui.

  "No, Dad, I can’t have your kidney. I don’t want you to suffer." Dai Rui won’t do it. She is afraid that her father’s health will collapse.

  "The doctor said, as long as you pay more attention, my body is no problem. You have a long way to go, and Dad hopes you can live a normal life. " Dai Junfu tried to persuade him, but he could only say these words. He felt that the words were very pale, but all the thoughts in his heart. It’s just that my daughter’s attitude is also very firm and she doesn’t want to drag her father down.

  During the stalemate, Dai Rui’s condition was very unstable, and she was critically ill several times. Her daughter even proposed to donate her cornea. Once he was critically ill in the middle of the night, Dai Junfu had already signed the consent form for organ donation. Fortunately, his daughter came back from the gate of hell.

  After three years of persuasion, doctors familiar with Dai Rui also helped with ideological work, and her daughter finally agreed to a kidney transplant. "I pulled her to go through the formalities that day, and I was afraid that she would go back on her word." Dai Junfu immediately arranged the application for surgery and reviewed the materials. Because the surnames of the father and the daughter use the same pronunciation but different words, the two also specially went to have a paternity test … … And all this is to queue up for surgery as soon as possible.

  In order to donate a healthy kidney to his daughter, he insisted on walking for two years and walking for an hour and a half every day. Get up at 6 o’clock in the morning, go out before 7 o’clock, and walk seven or eight kilometers to Qingcheng Mountain to work. After work in the afternoon, if you want to go home early to see your daughter, you will go home by car.

   Father loves nothing.

  I bought a wheelchair in the hiking city and pushed my daughter for a ride.

  On April 2nd, the day of the operation, Dad came to the ward to see Dai Rui.

  "Come on, take a selfie!" Dai Junfu proposed. "Son, don’t be vain. See you later!" After taking photos, Dai Junfu advanced into the operating room. An hour later, Dai Rui was also pushed in. A kidney with her father’s body temperature was placed in her daughter’s body, thus giving her a second life.

  On April 11th, in the ward of West China Hospital, both Dai Rui and her mother wore masks with neat braids. This is a critical period after her operation. Once she catches a cold, it is easy to cause lung infection. Dai Rui is filling out the postoperative observation form, how much water he drank and how much urine he discharged, and his handwriting is neat.

  "I am very attached to my dad. I have to hold his hand when I go out to play. He always says that I am still like a child." Dai Rui, 21, loves to laugh and listen to Jason’s songs. She says there is a lot of positive energy in the lyrics. Dai Rui said that when she was a little girl, she lost an infusion for 40 days, but she could only sit all the time because she was swollen, but she really wanted to go out and "let out the wind." Dai Junfu bought a wheelchair for this and said he would leave. Jinli, Kuanzhai Lane and Funan River are a big circle. "Dad, your feet don’t hurt? My ass hurts. " Dai Rui tilted his head and asked Dai Junfu behind him. Dai Junfu was a little proud. "It’s no problem to walk again!" Say that finish, both father laughed.

  Usually for dialysis, Dai Rui rides a battery car alone. It takes about 5 hours at a time from waiting to getting off the dialysis machine. She fainted twice because of hypoglycemia. Once when she was about to fall down, Dai Rui quickly called her father. "Dad, I feel terrible. I am at Qingcheng Bridge." Say that finish, just passed out. Good-hearted passers-by quickly called an ambulance and sent it to a nearby hospital for infusion. Confused, Dai Rui thought he was still doing dialysis, and his left hand never dared to move. When I woke up to see my father, the first sentence was "I’m so tired, please get off the dialysis machine." Dad lovingly said, "You got off the plane a long time ago. Now it’s time to save your infusion."

  "My dad’s cooking is delicious, especially baking tofu and all kinds of dishes." Speaking of which, Dai Rui’s mouth is watering. Because of the drug reaction, she always vomited after eating for a while, and Dai Junfu would try her best to make her something she wanted to eat. With renal osteopathy, Dai Rui’s feet often hurt, and Dai Junfu massages her every day to relieve the pain.

  "My mother and I are both sick, and my father has to spend a lot of energy to take care of us." Dai Rui said, but Dad is also very diligent and responsible for his work. He is not only an advanced earthquake relief worker in 2008, but also an excellent party member. In recent years, in order to cure the disease, my father borrowed money everywhere, scrimped and saved, and was not willing to buy a dress. In the same period, the Qingchengshan-Dujiangyan Scenic Area Administration, where Dai Junfu is located, has organized two fund-raisers, and with the help of relatives and friends, the family can survive.

   The past of critical illness

  Traveling to Chongqing is the only foreign trip for a family.

  Every afternoon after surgery, it is a fixed video time for Dai Junfu and Dai Rui.

  "Son, did you drink water today?" This is what Dai Junfu is most concerned about. After the operation, Dai Rui needs to urinate more than 2000 ml every day. She must drink water very hard. "Drink. I drank too much in the afternoon and just got up at night. " Dai Rui responded. "Drink more when you get up at night, and don’t have sex with your mother ‘ War ’ Now she is the only one taking care of you. " Dai Rui seldom talks back to her father, but she talks back to her mother. Dai Junfu couldn’t help telling her. "I see, do you drink much water?" Dai Rui cares about Dad. "What you drink is warm water." Dai Junfu "reports" to his daughter.

  Hanging up the phone, Dai Junfu flipped through the photo album at home and talked about the only trip out of the province for the whole family — — Chongqing trip in 2016. "My daughter proposed it. At that time, she experienced several critical illnesses and was afraid that she would not live long. She told me that she wanted to go out and play once." Dai Junfu is a bit sad to say. When my daughter was a child, because he worked in the back of Qingcheng Mountain and his wife was also working, she could only come back once or twice a month, and her daughter could only live with her grandparents. Although I am a tourism practitioner, I spend my holidays in my post, and I don’t have time to take my daughter to a distant place to have a look.

  "Then choose a place closer. You need dialysis on Monday." Dai Junfu suggested going to Chongqing, and her daughter agreed happily. A family of three got on the bus and went all the way to Chongqing. "In a hurry, I strolled down the street and took a cruise at Chaotianmen." Dai Junfu felt a little ashamed.

  The father and the daughter have been putting on a dragon gate array all the way. My daughter said, "Sometimes I feel like a dream, as if I woke up one day and I was a healthy body." Dai Junfu said that in fact, he often has such an idea, so WeChat is called "Waiting". He always comforts his daughter, too. Huaxi Dushi Bao-cover journalist Lai Fangjie’s photo report

Crispy and sweet "heart-shaped" cherries can only be eaten in these 20 days of the year! | Tan Life

Source: Ye Tan Finance and Economics
As soon as June comes every year, the season of eating cherries comes.
It doesn’t matter whether the "cherry freedom" is realized or not. It is always necessary to take advantage of these 20 days in a year and have a mouth addiction to be worthy of this "human agate".
This year, a cherry recommended by a life museum is a bit special, because-each one is in the shape of loving you.
Looks like a love, which makes people fall in love at first sight.
It tastes crisp and sweet, accompanied by a crunchy chewing feeling, so happy that people sigh: delicacies and delicacies can’t match a plate of cherries!
This is a cherry with honey beans from Dalian, which stands out from the cherries from many producing areas and varieties and has won unanimous praise from everyone.
Every cherry is naturally ripe on the tree, pollution-free and pesticide-free. It is delivered on the day of picking and remains "fresh" after receiving it.
It is large and even, with a super-large fruit diameter of 23mm~26mm, and it is full in your hand.
The fruit handle is green, too. It can squeeze water out, just like it just got off the tree. It’s very fresh!
The skin is bright and bright, with white spots scattered on it, like red agate, which looks good.
The appearance is natural heart-shaped, with sharp protrusions at the bottom.
Bite it down, and it was a little surprising, which was not the same as the cherry I had eaten before.
Its taste is a bit crunchy, and the flesh is very firm, with a little toughness and chewy.
Juice is abundant, and I feel it will flow out at any time. That sweet cherry juice mixed with crisp pulp is more than addiction! The whole mouth smells of red berries.
Spitting out the stone, the aftertaste in the mouth is still full of sweetness, and I ate a big plate unconsciously.
The stone is also super small, cut in half, and the stone is only a small part, almost all solid pulp.
Not only delicious, but also rich in nutrition.
It is rich in protein, vitamins, carotene and so on. In addition, the content of mineral elements such as calcium, phosphorus and iron is also high, especially the content of iron.
However, delicious food is not always there. These crisp, sweet and refreshing satsuma cherries can only be eaten in these 20 days of the year.
If you miss it, you will have to wait until next year!

Cherry with honey beans is a cherry variety introduced from Canada.
This variety of cherry has beautiful fruit shape and crisp and sweet taste. It is a new high-quality late-maturing cherry variety, and its taste and shape can be comparable to those of cherries imported from abroad.
The origin of this cherry with honey beans grew up in Dalian, Liaoning Province, bathed in warm sea breeze.
Dalian is located at the northern end of the suitable planting area of China land cherry, where there is abundant rain, long frost-free period and large temperature difference between day and night, which is very suitable for cherry growth.
The cooperative orchard is surrounded by mountains and rivers, with beautiful environment and far away from urban pollution.
Orchards are planted and managed by experienced local farmers. With decades of planting experience, they have a set of methods to take care of these cherry orchard.
Using the method of physical pest control, insect-proof boards were placed in cherry orchard.
Regularly weeding and loosening the soil artificially to maintain the benign ecology of the orchard. Apply farm manure instead of chemical fertilizer.
Cherry picking is also very particular. Experienced fruit farmers will not directly touch the fruit with their hands, but hold the fruit handle and gently break it up, and the cherry will be picked from the branches intact.
In order to ensure the freshness of cherries, they are freshly picked and made, put into insulated foam boxes and ice bags, and escorted by SF/JD.COM cold chain.
After receiving it, the cherries are still fresh and tender. If they can’t finish eating, they can be stored in the refrigerator.
Note: Cherries soaked in water are easy to rot. It is recommended to wash as much as you eat each time, so that they can be preserved for a longer time.

Can China Automobile Design Change the World? Geely automobile seizes the commanding heights of the industry

In the new era of electrified and intelligent automobiles, the international competitiveness and influence of China automobile enterprises are constantly improving. In order to promote the transformation from China manufacturing to China creation, China needs to create a brand-new design discourse system with its own characteristics.

On December 6th, the 10th Anniversary Forum of 2023 International Automobile Design and Geely Design was held in Shanghai. Dozens of influential figures covering production, learning, research and media were invited to attend and discuss with Geely how "good design has the power to change the world".

"Design is crucial. Design is not only an important reference standard for consumers to choose products, but also a key factor to determine product quality and the core competitiveness of Geely Automobile. " Yan Jiayue, CEO of Geely Automobile Group, said so.

According to reports, since its establishment in 2013, Geely Design has taken it as its responsibility to promote China’s independent automobile design in the new era. From "Damei China Car" to the rise of China’s independent design, to "Geely Yinhe" taking the lead in creating a new paradigm of China design in the era of smart electric. Geely constantly drives China automobile to climb the value peak again and again with its design, which affects the trend of automobile design in China and even the world.

Among them, Geely Yinhe E8 is the way out for Geely’s design-not compromising the existing conditions, constantly fighting against the entropy increase of design, and finding a beautiful order in the disorderly pattern.

Liu Ning, president of China Industrial Design Association, said: "We are very happy to see that it is an outstanding representative of an independent brand like Geely who is developing into a smart electric travel and energy service technology-based enterprise with global design competitiveness and influence, and constantly winning the recognition of the international community and global consumers."

Facing the opportunities and challenges of the times, China’s automobile design must change from single-point breakthrough to system capacity improvement. As Liu Ning said, "The design of new energy vehicles in China is not only the design of a single model, but also the design of the whole system, the whole value chain and the whole industrial chain".

If China’s automobile design wants to establish its own voice in the world, it needs to cooperate with all parties inside and outside the industry to participate in the promotion. The independent brand represented by Geely will promote the deep integration of Industry-University-Research, cultivate the future new force of China automobile design, and run out of the "acceleration" of independent training of talents.

In this forum, Geely Design, together with China Academy of Fine Arts, released the White Paper on China Automobile Design Discourse System (First Edition) in the field of automobile design in China, aiming at exploring the forward-looking thinking of China automobile design theory and system construction under the great changes. The release of this white paper has supplemented and improved the research system of automobile design in China, or it will become a landmark stop in the design history of automobile industry in China.

This year is the tenth year for Geely to explore the road of design. In the future, Geely Automobile will continue to contribute to the "good design" proposal of the world automobile development process and lead the industry to a new height in the development of the global automobile industry.

Why is the game fun | A book a day

Why is the game fun? Author: Wang Yahui, Version: Turing New Knowledge | People’s Posts and Telecommunications Publishing House, March 2023. (Poster design: Liu Xiaofei)

Recommended reason:

On May 12th this year, Nintendo released "the legend of zelda: Tears of the Kingdom", which sold 10 million copies worldwide in just three days, and triggered a wave of sharing among players on social media at home and abroad. With the development of media technology, the "ninth art" of games is increasingly attractive to people. Why is the game so fun? As a veteran gamer and the author of "The Game of China", Wang Yahui answers this fundamental question in a simple way through a large number of classic game cases such as Super Mario, Tetris, Diablo and the legend of zelda.

This book holds that games have clear and macroscopic "Rules" written in the instructions, and also have hidden and precise "Game Mechanics" that require players to explore themselves, while classic games can often derive the most complex and changeable mechanisms with the simplest rules. Judging from the two dimensions of time and space, which are the most basic for human beings to know the world, whether it is an extremely simple but popular elimination game such as Tetris and Bubble Dragon, or the most popular Jedi Survival, it is a superb use of the "space restriction" mechanism. Max payne, a classic adventure action game, tapped the potential of time mechanism through the use of bullet time.

In addition to space and time, this book also discusses the game mechanism in many aspects, such as money, props, skills, tasks, collection, etc., sorts out the classic design patterns in the study of game mechanism, and expands the horizons of ordinary readers to understand the game.

Meta develops multi-functional tactile skin Reskin, which can quickly improve machine sensitivity and tactile sensing accuracy.

Nowadays, artificial intelligence gradually integrates with human senses such as sound and vision, making communication between people more convenient. However, it is still challenging to integrate artificial intelligence with human touch.

To solve this problem, Meta AI and Carnegie Mellon University successfully developed a multifunctional, replaceable and durable tactile skin, and named it ReSkin. It can quickly improve the tactile sensing accuracy and sensitivity of the machine in the application process.

(Source:Proceedings of Machine Learning Research )

Related papers are titled "Multifunctional, Replaceable and Lasting Touch Skin" (ReSkin:versatile,replaceable,lasting tactile skins) published in [1].

Matai visiting researcher Raunaq Buhanlan (Raunaq Bhirangi), Tess Hellebrex, postdoctoral fellow and scientist of Pittsburgh Yuan Artificial Intelligence Research Center (Tess Hellebrekers), Mel Majdi, Professor of Robotics Institute of Carnegie Mellon University (Carmel Majidi), Abbina Gupta, Associate Professor of Robotics Institute of Carnegie Mellon University (Abhinav Gupta) is the author of the paper.

It is mentioned in the paper that ReSkin relies on machine learning technology and magnetic sensing technology, and has the advantages of being cheap, multifunctional, durable and replaceable. Specifically, ReSkin has low production cost, only 2-3mm thick, and can interact with the machine model more than 50,000 times. In addition, it has a high spatial-temporal resolution with an accuracy of 90%.Figure | ReSkin is the size of a coin and easy to manufacture (Source:PMLR)

Thin and high-precision specifications make it suitable for all kinds of machines, such as robot hands, tactile gloves, arm sleeves, etc. For specific processes, ReSkin can also provide tactile signals (high frequency) for the sliding, throwing, catching and clapping operations of the machine.

When Reskin is applied to different products, a large amount of relevant data will be generated, which can help researchers improve their tactile perception ability in AI systems.

Figure | Frequency changes of sensors applying ReSkin under different magnetic fields (Source:Proceedings of Machine Learning Research)

For example, ReSkin is an elastic sheet that can change its shape and contains magnetic particles. When its shape changes, it will release different magnetic signals. Researchers can use magnetometer to measure these changes, and use data-driven technology to convert the measured data into information such as contact position and applied force.

At present, many tactile sensing experiments are limited to one sensor level. This is because every time ReSkin is replaced, the machine needs to build a new model, which reduces the transmission efficiency.

Moreover, in different scenarios, each sensor needs to be thoroughly calibrated with the initial calibration procedure to match its individual response. This means that the calibration procedure must also adapt to these changes. In addition, as time goes by, soft skin like ReSkin will deform and need to be replaced, so it is difficult to popularize and apply it to different interactive scenarios.

In order to simplify the replacement process of Reskin, the researchers made innovations in three aspects.

Firstly, the researcher separates the internal circuit of the sensor from the passive interface, and does not need to be electrically connected with the traditional measuring electronic equipment. This operation effectively improves the sensitivity of the sensor, and it is as simple as sticking a sticker when replacing worn ReSkin.

Secondly, the researchers use the output data of several sensors to improve the model mapping. Through this operation, researchers can use a higher data diversity training model. This helps the sensor to output more effective and generalized data.

Thirdly, thanks to the self-supervised learning mode of the machine, researchers don’t have to collect calibration data for each new sensor, but use a small amount of unlabeled data to automatically fine-tune the sensor.

It is known that the existing camera-based tactile sensor requires a very small contact distance between the surface and the camera, which leads to a heavier machine. In contrast, ReSkin can cover the hands and arms of humans and robots, which facilitates researchers to develop multifunctional, expandable and inexpensive tactile modules. This is impossible for the existing artificial intelligence tactile system.

In order to highlight the practical value of ReSkin and show its unique charm of promoting the development of artificial intelligence, researchers apply it to different machine scenes. From grasping tiny objects to measuring the force exerted by the dog’s feet, from building a continuous ReSkin with wide coverage to measuring the field contact force, ReSkin has shown its extremely high flexibility and practicality.

Although researchers have demonstrated the technical advantages of ReSkin in contact location and force prediction, ReSkin still has great development potential in the future.

The experiment of this paper is based on the single-point contact of the machine, and the goal of scientists is to further study the application of ReSkin under multi-point contact. Another interesting future development direction is to specifically analyze the influence of external magnetic field and metal objects on ReSkin’s perception ability.

In addition, based on ReSkin’s high time resolution of 400Hz, researchers can make use of this advantage and use dynamic time series data to create better machine models. In a word, scientists believe that ReSkin will promote the machine’s touch perception ability and be able to apply it to practice.

What is the relationship between the first batch of the first batch of millet and Qualcomm?

Zhongguancun Online Message: Lenovo Interpise Hu Xiaomi’s starting flagship chip is the second time.The first time is two years ago, Snapdragon 855, the responsible person of the Lenovo mobile phone business at that time was still the manner we are familiar with the shopkeeper.

After a year, Lenovo once again grab the first hair of the Snapdragon High-end flagship chip and did the world’s first.Where is Xiaomi?The first Qualcomm flagship chip has suddenly collapsed for many years?

In addition to the high-end flagship chip, the second flagship dragon 870 is also losing from Xiaomikou.This makes us have to doubt, is Xiaomi can’t work?The first shot becomes the first batch. It may be better twice. If it is a regular loss, there is really a problem.
