About skiing, these reminders must be seen.

You need to know this about skiing.

Everyone has no clear concept of skiing. As a competitive sport, skiing is risky. Skiing requires professional skills, as well as knowledge and the importance of related equipment. Many people misunderstand that skiers’ own contempt for safety is a major cause of accidents.

1. Skiing at intermediate level is an extreme sport.

Snow trails are divided into primary greenway, intermediate blue road, advanced underworld and expert double underworld. According to different slopes, the suitable people are different.

Skiing is also graded, and most people are suitable for primary skiing. In the early stage, coaches are needed to take the introduction. Above intermediate level, it can be regarded as extreme sports.

2. You are falling at a high speed, like a "cannonball"

Many people think that the snow is soft and it doesn’t matter if you fall, but on the snowy road, people who slide at high speed under the acceleration of gravity are tantamount to "huge shells" and are likely to rush out of the snowy road, which is very dangerous.

3. Wear safety equipment.

There have been skiers who died on the spot after falling without wearing a helmet, so safety equipment can help you reduce the chance of injury as much as possible. Especially for beginners, they should use safety equipment: brightly colored ski clothes, ski pole, ski goggles, sports wrist pads, sports knee pads, sports hip pads and ski helmets.

4. Do what you can, and don’t underestimate your own safety.

In order to seek excitement or satisfy vanity, some beginners go skiing on the intermediate snowy road. Please learn to ski in the right steps, know your ability correctly, and don’t try too hard easily.

Beginners often sit in the middle of the snow trail and chat during breaks. It is very dangerous to stay in the middle of the snow trail. If you want to rest, you should stay on both sides of the snow trail and observe the route and speed of the skiers above.

5. Abide by the international snowy road principle.

Skiers should follow the international principle of snow trail, that is, the "traffic rules", slide on the snow trail as far away from other skiers as possible, keep a relative distance, and leave an adjustment distance for themselves and others.

You should pay attention to these when taking children skiing.

Skiing not only exercises children’s physical fitness, but also feels the charm of nature. At the same time, it can also enhance the feelings between parents and children. It is really a good thing to win at one stroke. However, it is dangerous to take children skiing. How to prevent the danger? Please pay attention to these things when taking children skiing:

1, the age should be up to standard

When parents take their children skiing, the first thing to consider is the age of the children. The children are over 5 years old, and they are in good health and not sick when skiing, so that the children can have a full understanding of skiing. Only when these conditions are met can we take our children skiing.

2. Choose a ski resort suitable for traveling with children.

When you take a child skiing for the first time, you must choose a suitable ski resort. Ski resorts with children’s skiing events and children’s activity areas are definitely the first choice. These children’s projects and activity areas can not only ensure the safety of children, but also make them enjoy themselves.

3. Armed to the teeth

Choose suitable equipment for children, colorful ski clothes, waterproof gloves, and wear special helmets, wrist pads and knee pads for skiing.

Helmet, for safety, helmet is a must!

In snow goggles, even on cloudy days, the reflection of sunlight in the snow is stronger than we thought. Snow goggles is not only resistant to strong sunlight, but also can protect against wind and snow. Snow goggles is essential to protect children’s eyes.

4. Exercise properly

In sports, we should pay attention to what we can do and do it according to the children’s situation. You can take your child for a walk in the snow first to adapt to the environment. Don’t choose a site with too big a slope.

5, accompanied by parents

Don’t let children ski alone, especially in the mountains. Let the children slide on the obvious and spacious snowy road, pay attention to other skiers and don’t let the children leave your sight.

6. Slow down and make everything controllable.

Please slow down all the steps, from choosing ski equipment to going skiing in the ski resort and taking children skiing, so as to make everything controllable for safety.

7. Bring an extra helper

In the process of skiing, it is always inevitable that there will be falls, poor care or unexpected situations. If you can, take one more family member or friend to travel, so as not to be in a hurry.

8. Please grasp the time.

Skiing will consume a lot of physical strength. Children go skiing mainly to feel happy, play some snow games, relax, and also relieve tension and pay attention to grasping the time.

Skiing is an interesting and dangerous sport, and safety comes first. Be sure to do what you can, learn the necessary safety knowledge, and choose the corresponding level of ski trails according to your own technical level. Beginners must ski under the escort of regular coaches, and skilled skiers should also pay attention to relevant safety protection. In the event of accidental injury during skiing, you must call the rescue number of the ski resort in time to seek medical assistance.

Ping pong! president

After the meeting, Turkish President played table tennis, and the table "showdown" was exposed.

According to the Harbin News Agency, on the 12th local time, Kazakh President Tokayev met with visiting Turkish President Erdogan in Astana, the capital. After the formal talks, the two presidents played table tennis.

On 12th, the Kazakhstan News Agency announced the picture of the "confrontation" between the two presidents on the ball table. After the "match", the two men laughed and shook hands. This is not the first time Tokayev and Erdogan have interacted on the table. They also played table tennis together after their meeting in Ankara in May. Kazakh media said that Tokayev loves table tennis very much.

According to the Information Bureau of the Presidential Office of Kazakhstan, on 12th, after the bilateral meeting between Kazakhstan and Turkey and the fourth meeting of the high-level strategic committee, Tokayev and Erdogan held a joint press conference at the Presidential Office.

Kayev said that Erdogan’s visit coincided with the 30th anniversary of the establishment of diplomatic relations between the two countries. The two sides signed a series of important documents at the fourth meeting of the High-level Strategic Committee, and planned to increase the bilateral trade volume to 10 billion US dollars.

A large number of clinical studies have confirmed that there is a close relationship between microorganisms and diseases. Therefore, it is particularly important to infer the relationship between potential microorganisms and diseases. Professor Liu Jinxing’s research team proposed a new method based on network consistency projection and label propagation to predict the relationship between microorganisms and diseases. Methods The medical thesaurus and 16S rRNA gene sequence were used to calculate the semantic similarity of diseases and the functional similarity of microorganisms, and the network projection scores of microbial space and disease space were obtained by increasing the network consistency projection. Finally, the disease-related microorganisms were accurately predicted by the tag propagation method.

The association between miRNA and diseases is an important part of preventing, diagnosing and treating complex diseases. Professor Liu Jinxing’s research team proposed a deep learning method to predict miRNA- disease association by using a deep automatic encoder with multi-core learning. Firstly, the multi-core learning method was applied to construct miRNA similarity network and disease similarity network respectively, then the integrated miRNA feature representation and disease feature representation were input into the deep automatic encoder, and finally the new miRNA- disease association was predicted by the reconstruction error method.

In order to make effective use of single cell data and better explore the heterogeneity among cells, Professor Liu Jinxing’s research team proposed a consensus guidance model based on graph automatic encoder. The model generates feature matrix through feature learning, and carries out similarity learning based on distance fusion method. The model can accurately identify key features and effectively save the internal structure of data, which improves the accuracy of cell type identification.
