The “June 13″ gas explosion accident in Shiyan, Hubei still affects people’s hearts. On June 14, the Office of the State Council’s Security Committee and the Emergency Management Department held a video conference on national safety and precaution work, expressing the need to thoroughly investigate the accident process and causes, and to hold accountability in accordance with laws and regulations. Prior to this, Hubei Province also carried out safety production inspections and management work, including the gas industry, through the issuance of emergency notices and emergency meetings. With the disclosure of more information, while the explosion accident locked the two-story building with a history of nearly 30 years, the safety of the old community has also become the next focus of attention.

Accountability: the State Council listed for supervision

At about 6:40 on June 13, a gas explosion accident occurred at the Yanhu Community Fair in Zhangwan District, Shiyan City. As of the evening of June 14, the accident had caused 25 deaths. At present, the on-site search and rescue is still continuing.

Recalling the scene of the explosion, the owner of a plaster shop near the bazaar described it to a reporter from Beijing Business Daily: “The glass on the facade of our shop was blown up. I lived behind the shop and went out to look at it when it exploded. serious.”

According to the official Weibo report of “Shiyan Release”, the scene of the explosion was the Yanhu Community Vegetable Market in Zhangwan District. It was a two-story building constructed in the early 1990s. The first floor belongs to Runlian Property and the second floor belongs to the management of Yanhu Community. . Among them, there are 19 pharmacies, breakfast shops and other shops on the first floor, uninhabited activity rooms on the second floor, and 46 convenient stalls across the road.

According to the official website of the National Health Commission, the National Health Commission has sent a team of 6 emergency medical rescue experts to Shiyan, Hubei. As for the specific cause of the gas explosion, the official investigation results have not yet been released.

On June 14, the State Council Security Committee decided to supervise the investigation and handling of the gas explosion accident in Shiyan, Hubei. The meeting emphasized the need to deeply learn the lessons of the gas explosion accident in Shiyan, Hubei, draw inferences from one another, deepen the investigation and management of hidden dangers in various regions and key industries, and further strengthen safety Supervision and law enforcement inspections resolutely curb the proliferation of various accidents, and effectively protect the lives and property safety of the people. It also requires meticulous search and rescue work, effective treatment of the wounded, and best efforts to reduce casualties; thorough investigation of the accident process and causes, and serious accountability in accordance with laws and regulations.

In addition, the meeting requested that the key points should be highlighted, and key units and sites that may cause heavy casualties, such as chemical storage tanks, large-scale complexes, chemical parks, densely populated areas, gas and oil and gas pipelines, and various mining enterprises, should be closely guarded. Strictly prevent serious accidents. To deal with problems that seriously impact the safety of the people, such as the chaotic management of gas laying, the hidden fire hazards of moving and moving to high-rise buildings, the disorderly construction of chemical energy storage power stations, and the illegal manning of agricultural vehicles, we should promptly take control measures.

Remediation: a major investigation in the gas industry

At present, the cause of the accident is still inconclusive. So, what are the possible factors that will lead to a gas safety accident? Lin Boqiang, dean of the China Energy Policy Research Institute at Xiamen University, told the Beijing Business Daily that there may be multiple reasons. “The gas explosion may be related to urban expansion. In our infrastructure, all gas is taken from under the city. When wiring in the past, it is reasonable to keep the gas as far away as possible from the residential area. If it is in a residential area, there will be some special requirements for the wiring. However, due to urban expansion, areas that were not communities may become communities. It may be difficult to modify the original pipelines. However, the new pipelines may also cause safety accidents. This can only be determined after the investigation results come out.”

“How to make pipelines safer through renovation is a key thing. In the process of urban expansion, it is very important to update and upgrade infrastructure and equipment.” Lin Boqiang said, “In addition, equipment problems and human factors may cause gas. explosion.”

June this year is the 20th National “Safety Production Month”, and the occurrence of gas explosion accidents has also set off a wave of rectification of potential safety hazards. On the day of the accident on June 13, Hubei Province issued the “Emergency Notice on Doing a Good Job in Current Work Safety” (hereinafter referred to as the “Notice”) to deploy gas safety inspection and rectification work.

The “Notice” requires that a large-scale investigation and rectification of potential safety hazards such as natural gas pipelines (high-pressure pipeline networks), urban gas pipeline networks, and liquefied gas tanks (tanks, storage, transportation, and use) should be carried out quickly throughout the province to eliminate hidden dangers and ensure safety. Strictly investigate behaviors that do not implement real-name management of gas cylinders in accordance with regulations, strengthen the investigation and treatment of hidden safety hazards such as gas appliances, connecting hoses, pressure relief valves, and gas leak alarm devices in gas use places such as restaurants, and vigorously rectify illegal storage and transportation of bottled liquefied gas , Filling and upside-down, as well as unauthorized removal, modification, relocation, burying of gas facilities and appliances and other issues.

In addition, in view of the hidden dangers of pipelines, it is also required to organize the investigation of hidden dangers such as pressure, cross crossing, and insufficient spacing of oil and gas long-distance pipelines, and strengthen the supervision of hidden danger rectification. Strengthen the risk management and control of pipeline high-consequence areas, especially personnel-intensive high-consequence areas. Strengthen pipeline inspections and the management and control of surrounding third-party construction sites to prevent illegal construction from endangering pipeline safety. Carry out the investigation and treatment of geological disasters such as landslides, mudslides, and collapses around pipelines, and implement geological disaster prevention measures.

Prevention: focus on old communities

In addition to the inspection and rectification of production safety in key industries, fire prevention problems should be prevented from “burning”, and we must also focus on important places such as old communities.

At the emergency video conference on production safety in Hubei province on the evening of June 13, the secretary of the Hubei Provincial Party Committee Ying Yong emphasized that it is necessary to carry out comprehensive and in-depth investigations and remediation of hidden dangers in production safety, focusing on natural gas transmission and use, mining, electric power, chemical engineering, In key areas such as transportation and key places such as old communities, bazaars, tourist attractions, etc., thoroughly investigate and eliminate hidden risks.

“In urban construction and renewal, we must not only pay attention to planning management, but also strengthen building codes, and strictly implement the requirements of building safety and quality.” Ying Yong said.

Yan Yuejin, research director of the Think Tank Center of E-House Research Institute, told reporters from Beijing Business Daily that it is necessary to conduct key research on public safety issues related to housing, especially gas pipelines. If they are not handled well, various new problems will easily arise. May affect the operation of the entire city. As for the problem of gas pipelines, the follow-up also requires old communities to increase inspection and management to prevent risks.

According to reports, the Wuhan Municipal Housing Management Bureau will investigate the city’s hidden housing safety hazards, hidden fire hazards in property communities, hidden fire hazards in rental houses (including long-term rental apartments), hidden fire hazards in public rental houses, and hidden fire hazards in historical buildings, with a focus on registered dilapidated houses and old buildings. A comprehensive inspection of the house was carried out.

In addition, strengthening public education is also the top priority of safety. Wuhan will also focus on strengthening security inspections for large-scale commercial gas users and small-scale catering users of bottled LPG. Natural gas companies should conduct inspections and repairs on users’ valves, pipelines, meters, etc., to help users eliminate potential safety hazards and improve users’ awareness of safe gas use.

“China’s safety has always been the first priority, but it does not mean that there are no problems. The government must review the company’s safety thresholds and carry out strict rectification, and the pipelines running under residential areas must be renovated to be safer. In addition, Gas education on the consumer side is also very important. Forgetting to turn off gas, aging equipment, improper operation, etc., will cause hidden dangers. We must strengthen gas safety education for the public, and gas suppliers and communities should conduct safety publicity to explain its benefits.” Lin Boqiang said.

The competition in the Korean entertainment industry is very fierce, every year there are many new artists born, in addition to professional ability and talent, they also have strict requirements on appearance. That’s why Korean artists do not distinguish between men and women, almost everyone has their own secret to losing weight. “The goddess of bare face” or “the nation’s first love” Suzy is no exception. From her plump figure to her chubby face, Suzy has succeeded in losing weight, getting a small face and slim figure, all thanks to her own menu. Let’s learn from Suzy’s weight loss meals. According to Suzy, when she debuted as a member of the girl group Miss A at the age of 16, she had a rather fat body compared to most female idols. After that, Suzy was forced to lose weight, she worked out hard and persevered with her own diet. “National first love” also revealed her weight loss menu in a TV show. For breakfast, she only eats 100g of sweet potato + 50g of chicken breast and half a cup of skim milk. For lunch, Suzy eats a small bowl of brown rice and a vegetable salad. Only eat 2 more sweet potatoes for dinner, especially before 6pm. After that, do not eat or drink anything other than water. Seriously maintaining this diet, Suzy has successfully achieved a slim but healthy body. It is known that Suzy also maintains a diet rich in fruits and drinks a lot of water. According to her, this is a way of detoxifying the body, both supporting weight loss and making the skin youthful. Equally important, Suzy said she often practices choreography to stay in shape. In order to keep her stomach slim, Suzy often does sit-ups. She usually exercises at least 30 times in the morning or at night before going to bed. The female idol and actress often perform another rather special move, helping to tone the upper body. It is a movement that simulates the shape of a penguin. According to Suzy, this move must be practiced quickly, until the body feels warm to be effective. It can be seen that, in order to lose weight and keep fit, Suzy was really serious about implementing a minimalist diet combined with regular exercise. After all, the secret lies in perseverance and hard work. The beauty standards of Korean stars

Summer is approaching, and it is the season when makeup begins to melt away. Especially now that you have to wear a mask to live your life, the skin is especially prone to dissolve the makeup in a doubly cramped environment. When you want to take off the mask, you will often be frightened by the makeup. If you want the makeup to stick to your face obediently, the skin must have enough moisture, and you must also learn how to make up. At this time, a moisturizing spray is very important. However, many people think that the use of moisturizing spray is to spray it on the face desperately. In fact, there are many points to pay attention to!

Moisturizing spray ingredients

The ingredients of the moisturizing spray are very important and can directly affect the moisturizing effect. Generally speaking, only when ingredients such as hyaluronic acid, niacinamide (vitamin B3), glycogen, sucrose, trehalose and sodium PCA are contained, can the water-locking effect be achieved. On the contrary, if the ingredients contain a lot of spices and alcohol, not only will they easily cause skin problems, they will also evaporate quickly when sprayed on the face, and even the skin’s own moisture will evaporate, making the skin drier instead. In addition, girls with sensitive skin can choose products with more natural ingredients, or those with natural minerals, which will cause less skin irritation.

In addition to the ingredients, the density of the moisturizing spray is also very important. If you want to increase the moisturizing ability, you can choose a product with a higher density and a finer mist point, which can make the pores more easily absorb the spray and immediately allow the skin to absorb water.

Correct way to touch up makeup

Many people know that they should use a moisturizing spray before touching up makeup, but they don’t know the correct way. In fact, the most correct method is to wipe off the sweat and dissolved makeup on the face first, and then spray a moisturizing spray at a distance of about 30cm, and print it off with a tissue to remove any excess oil and dirt on the face. Go; then spray the moisturizing spray again, then gently pat it with your hands to let the skin absorb, and finally use the powder to touch up makeup.

Other usage of moisturizing spray

In addition to makeup, you can actually use moisturizing spray after exercise or after exposure to the sun to cool the skin and at the same time replenish the moisture lost by the skin.

After the terrible shooting in Atlanta (Georgia) in mid-March, Tam Nguyen organized self-defense classes for the Vietnamese community in Garden Grove, California. The purpose of the class is to help members protect themselves from racist acts against Asian Americans. Photo: Reuters.

The shootings at three spas in the city of Atlanta have left 8 people, including 6 women of Asian descent, dead. The suspect said he suffered from a sexual addiction and the women were “tempted”. The shooting occurred amid rising Asian stigma attacks in the United States during the epidemic, which also sparked debate about stigmatization against Asians and a recurring image. the sexualization of Asian women in America. Photo: Reuters.

The Covid-19 pandemic prompted Nguyen to set up “Nailing It for America”. This organization accepts donations and distributes personal protective equipment for medical personnel, with a device value of about $ 30 million. In addition, the organization also provides food for the elderly isolated by the pandemic. When the shooting happened, the organization’s goal changed, focusing on helping the Asian community as well as colleagues in the beauty industry. Photo: Reuters.

Self-defense classes have also been offered in many other parts of the United States. Officials and police are also involved in teaching students and members of the Asian community how to avoid becoming victims and what to do when something goes wrong. Photo: Reuters.

“Violent situations are happening more and more. As an Asian woman, I really want to know what to do when I am in that situation,” said Vy Truong, a student. Photo: Reuters.

At the Tam Nguyen family-owned beauty salon, masters teach about 50 students for a period of one to two weeks. Lessons focus on getting away and escaping from the attacker. In addition, the masters also taught how to counterattack to pin enemies to the ground and attack at vulnerable locations. Photo: Reuters.

Tam Nguyen is a co-owner of a beauty salon in the city of Garden Grove. His family center has helped 50,000 students graduate in 35 years of operation. Most of the trainees are of Vietnamese origin. Photo: Reuters.

According to US census data, 40% of the population of Garden Grove is of Asian descent. In the nearby city of Huntington Beach, many white daemons regularly gathered to protest. Photo: Reuters.

But if you build a house Not people, but AIWhat?

This is the scholars from Copenhagen University of Information Technology, York University and Shanghai University, using 3D Neuron Cell Automata (NCA)New research completed.

Not only can Generate static structure, Of course not only apartments, but also trees and castles:

Can also generate Functional machine, Such as a crawling caterpillar:

Put it all in two paragraphs and still play Regeneration, A successful clone…

(Huh~ I have a sense of the picture)

how did you do that?

Application of Neuron Cell Automata

Researchers are actually influenced by the “Game of Life” Cellular Automata (CA) Inspired, developed on the basis of 2D 3D Neuron Cell Automata (NCA).

“Game of Life” is made based on the principles of cellular automata, which can also be said to be a demonstration of cellular automata.

It was invented by the British mathematician John Conway in 1970. In the grid, each square is inhabited by a cell, Its state is determined by the 8 surrounding cells, Black represents cell survival.

Since then, many studies have adopted more complex neural network rules, known as Neuron Cellular Automata (NCA). However, most of its applications are limited to 2D structures, or only simple 3D structures can be generated.

In order to improve the versatility of NCA in practical applications, the research team developed 3D NCA.

It uses 3D convolutionCapture more cells around to generate complex 3D structureAnd has More typesConstruction unit.

△3D Neuron Cell Automata Update Rules

Researchers are trying to use NCA to generate target entities from a single living cell and use supervised learning to optimize reconstruction loss.

In addition, the entities in “Minecraft” are used as cells in the 3D grid, and their state vectors include: block type, survival state, and hidden state.

However, since each unit is a single block type, they treat the structural reconstruction task as a Multi-class classification problem, Predict the type of a given unit.

Using the combination of LogSoftmax and NLLLoss methods provided by Pytorch, the realization is between the target and the predicted cell structure, Minimal cross entropy loss.

This loss leads to unstable performance**, and the model exhibits a preference for “air” blocks.

In training, the “air” block usually occupies most of the selected structure, therefore, Unbalanced training dataMay cause the model to over-predict.

To solve this problem, the researchers divided the loss calculation into two parts according to whether it was classified as an “air” block, and added a Crossover overlap (IOU) cost, To measure the absolute difference between the non-“air” block and the entity to improve accuracy.

How’s the effect?

For the model in static structure and dynamic function machine Refactoring performance, The researchers evaluated and recorded various parameters.

The results show that the reconstruction ability of NCA has Robustness:

△Normalized IOU/Structural Loss

△Normalized total loss

However, NCA is Build larger entities(E.g. church) is still challenging because the model often falls into a local minimum and takes longer to train.

Although the cathedral model has lower losses than some entities, there are many Randomly generated structure, So no other entities are natural. Comparison of target structure and generation effect:

In addition, it is more difficult to generate more random entities in nature (such as oak trees).

As mentioned earlier, NCA can Generate static structure, And can well increase the number of single block types, generating Diverse and complex interior, Such as inside an apartment building:

Surprisingly, in the jungle temple, NCA even generated an arrow trap.

When generating functional machines, the researchers found that Different structures have different generation modes:

Some structures gradually expand from small cells to their final form; while caterpillars are rapidly formed first, and then eliminated cells to form the final structure.

△Source: Science Magazine

In addition, the regenerative properties of NCA are also a highlight. In addition to the growth of complex structures from a single cell, these local renewal rules also allow Regenerate or repair damage.

Even without training, it can still restore some damaged structures, such as trees:

However, the researchers found after comparative testing:

Without regeneration training, the regeneration rate of the model is only 30%; after regeneration training, the regeneration rate can reach 99%.

3D NCA has attracted widespread attention from netizens, and some netizens mentioned on reddit:

The application of NCA in physics is also worth exploring. For example, it can be used to simulate crystal formation.
