Can you tell these derivative models of the F-35 from the "Lightning II" family?

  According to the report of Flight International on April 16th, the US Navy and Marine Corps successfully completed the first test of the concept of "lightning carrier". Twenty F-35B fighters with short take-off and vertical landing took off from the US Navy "Tripoli" amphibious assault ship to perform fast-paced operations.

  The concept of "Lightning Carrier" was formally put forward in 2016, based on the existing "F-35B vertical takeoff and landing aircraft+amphibious assault ship" model of the US military. The name of "Lightning" in the concept comes from the F-35B Lightning II Joint Strike Fighter, and F-35B is just one of the F-35 Lightning II Joint Strike Fighter (JSF) models.

  F-35 "Lightning II" Joint Strike Fighter (JSF) is a single-seat single-engine multi-role fighter and a low-order auxiliary aircraft of F-22. It has strong stealth capability, advanced avionics system and certain supersonic cruise capability, and is mainly used for frontline support, target bombing, air defense interception and other tasks. It is divided into three types: conventional takeoff and landing (CTOL)F-35A, short takeoff/vertical landing (STOVL)F-35B and carrier-based (CV)F-35C. Undoubtedly, in the future competition for air superiority, F-35, as one of the world’s advanced fifth-generation aircraft, has a very high photogenic rate. So how do you distinguish them in appearance?

  The F-35 "Lightning II" Joint Strike Fighter (JSF) was mainly developed by Lockheed Martin of the United States, and eight countries including Britain, Italy, Netherlands, Denmark, Norway, Turkey, Australia and Canada participated in the development, with a total cost of $276 billion.

  In addition to R&D abroad, South Korea, Japan and Israel also vigorously purchased the F-35 to enhance the overall air combat capability. Therefore, according to the current data, a total of 12 countries have decided to equip the F-35:

  According to the above picture, there is Israel’s Star of David emblem above the wing, which is an F-35A. (Architecture A, called F-35I, shows the F-35A fighter equipped by Israel Air Force. )

  two

  character

  The U.S. Air Force, Navy and Marine Corps are equipped with three types of F-35 fighters, which are not a panacea according to their badges. If it is an F-35 equipped by the US military itself, it can be roughly distinguished by the characters in the belly position below the horizontal tail:

  1. Symbol of the United States Air Force (F-35A of the United States Air Force)

  2.NAVY (F-35C of the US Navy)

  3.MARINES (The United States Marine Corps purchased two models, F-35B and F-35C).

  In addition, there are several F-35Cs in the US Navy that also say "MARINES". But what should I do if I can’t see the military emblem or characters from the photo point of view? This uses the "shape resolution method".

  three

  wing span

  Both F-35A and F-35B have a wingspan of 10.7 meters, while F-35C adopts a large wingspan design to reduce the landing speed, and the wingspan is increased to 13.1 meters and can be folded, which is the largest of the three sub-models.

  four

  nose gear

  In order to withstand the impact of the ship, the F-35C has thickened the front landing gear, and changed from the basic single-wheel landing gear to the two-wheel landing gear, and the front landing gear has the unique ejection pull rod of the ejection take-off fighter. The following figure shows F-35A, F-35B and F-35C in turn.

  five

  Landing tail hook

  The landing of the F-35C needs to be stopped, and a repeatedly used stern hook is equipped under the engine. Although the F-35A will also be equipped with crash landing tail hook, it is currently testing the tail hook crash landing, and even if it is installed, it will be one-off.

  six

  regula

  The leading edge of the main wing of the F-35C is moved forward to increase the wing area, which leads to the strake wing in both the F-35A and the F-35B, but it is cancelled on the F-35C. The following figure shows F-35A, F-35B and F-35C in turn.

  seven

  Jibei

  F-35B is a short takeoff/vertical takeoff and landing type. Due to the special requirements of takeoff and landing mode, the engine of this type adopts a lift fan device. When viewed from the top, the rear of the cockpit is flat, and the upper cover of the lift fan and the cover plate of the auxiliary air inlet will open upward during the takeoff and landing.

  eight

  Machine gun

  The F-35A is the only one of the three sub-models, which adopts the built-in gun design and is equipped with a GAU-22/A four-tube 25mm gatling built-in gun. Therefore, there are obvious protrusions on the front upper part of the left wing of the fuselage, which is a remarkable feature of the A-type aircraft. F-35B and F-35C are not equipped with fixed cannon, so it is enough to mount the cannon pod on the belly line when necessary.

  nine

  Verifier, test aircraft and

  Low speed initial production aircraft

  The test aircraft and the initial low-speed production F-35 are usually numbered on the fuselage. For example, before the mass production of the F-35A, the aircraft fuselage numbers AA-01, AF-01 to AF-07 were even directly marked with F-35A, all of which contained "A"; F-35B has BF-01 to BF-04 with "B" in them; F-35C has CF-01 to CF-05 before the first mass-produced CF-06, all with "C".

What is the origin of Sun Honglei’s daughter’s birth wife Wang Jundi?

1905 movie network news On December 16th, Sun Honglei, a 47-year-old actor, gave good news in Weibo and was officially promoted to be a father: "My baby daughter was born, and the mother and daughter are safe. I will share it with you as soon as possible. Thank you all, love you and be grateful."

Previously, Sun Honglei answered the question of whether he wanted a boy or a girl in an interview. Sun Honglei’s answer at that time was: "This is arbitrary. In fact, I wanted a boy before, because my three brothers and our two brothers are girls. I thought there must be a boy to carry on the family line, but now I have fully figured it out, that is, to be happy and happy."

Actor Sun Honglei and his wife Wang Jundi got married in Paris in 2014, ending a seven-year love run. However, doubts about his wife Wang Jundi began when he officially announced his marriage.

Wang Jundi, 32, studied music and dance, and is a singer. At the age of 14, he was admitted to Shenyin Affiliated High School with the first place. After graduating from high school at the age of 17, Wang Jundi went to Austria to continue studying vocal music. During his study at the Vienna Conservatory of Music in Austria, he advanced placement several times with excellent results.

It is reported that Wang Jundi’s years of studying abroad are very hard, and he often walks aimlessly on the Danube River alone. When he sees a telephone booth, he rushes to call his family, and the process of integrating into local life is particularly long.

Wang Jundi has participated in many performances and competitions, and won the first place in the 11th National Young Singers’ Grand Prix of CCTV, the Vienna sound of spring Singing Evening, and the first place in the 2005 Phoenix Cup European Chinese Youth Will Award Singing Competition.

In 2005, Wang Jundi took part in the Chinese singing competition held by Phoenix TV. At that time, someone asked her if she wanted to take part in the Miss Universe beauty pageant, and if so, she would send me a form. Later, she gave it a try and successfully passed the competition in Germany. Finally, it successfully entered the top 50.

On the eve of National Day in 2008, the sweet photos of Sun Honglei and Wang Jundi visiting Wangfujing were exposed by the media. Then, there are frequent photos of two people going out. It was not until 2009 that Sun Honglei and Wang Jundi were photographed holding hands to attend the event that Sun Honglei confessed that his girlfriend was a singer.

Sun Honglei has always kept a low profile in dealing with emotional problems, but occasionally Xiu Xiu loves to sprinkle a handful of dog food. For the birth of her daughter, netizens expressed congratulations in succession. LAY forwarded Weibo and said, "And I’m uncle LAY now, right, Brother Hong Lei? Ha ha ha ha ha "

Why did Liu Qingyun’s "New Love" become a Chinese love classic?

1905 movie network feature IFAnd one day,We can work withAlien Civilization Dialogue****



If that day comes,We’re going to pick a classic film.On behalf of human civilization in our century,How to choose?


So,What kind of movie is worthy of being called a classic movie?


Are those films with deep storylines, brilliant performances, and unique artistic styles that have had an important impact on film history?


There is no denying that a movie that meets this definition is indeed a good movie


But to recommend to aliens who want to understand the culture of the earth, which one can summarize the achievements of human civilization?


Perhaps we also need some relative classics,That is, the movie that appeals to most of the human population on Earth.


What if we combined these characteristics and recommended a movie that could not only explain the background of the times, but also tell the complexity of human thought, and also sell well?


It is the classic Hong Kong love movie that will be broadcast to you this week by "A Good Film Date".


In 1993, in the era when martial arts films and comedies were flourishing, this movie, as a quiet and even a slightly "cliché" romance, actually achieved an impressive box office score of 30 million yuan, and won six awards including Best Film Award and Best Director Award at the 13th Hong Kong Film Awards.


The reason why "New Love" can become a classic,It is because after the washing of the times,There are still topics that can be discussed,It is a classic movie that is often seen and updated.


Just like Ajie in the film, he faces the confusion of love and career choices, and it is still the confusion of contemporary young people today.

The reporter’s comments on the investigation of "rewarding" chaos in live webcasts are shocking.

CCTV News:In recent years, with more and more users sharing their lives, showing their talents and launching social activities on the webcast platform, the attention of the webcast platform is getting higher and higher, but it also exposes some problems, such as bad performances and propaganda of getting rich overnight. Recently, an article describing that a network anchor won a reward of 10 million yuan from netizens in a short time was circulated, and getting rich by "rewarding" caused controversy. In this regard, our reporter launched an investigation.

Reporter:This is a live broadcast of a network anchor on a certain platform, and some viewers keep giving her virtual gifts. This gift called "Supreme Guardian" is equivalent to RMB 10,000. In a live broadcast, the anchor received 30 gifts with a total value of RMB 300,000.

Not long ago, an article about the anchor’s "reward" of 10 million yuan in a short time was circulated on the Internet, in which it was said that she had broadcast more than 600 live shows in recent years, and accumulated virtual gifts equivalent to 30 million yuan. The "reward" mentioned in it refers to the audience buying virtual currency through the live broadcast platform and then converting it into virtual gifts for the anchor. The live broadcast platform will convert the value of the "reward" gift and share it with the anchor, which is an important source of income for them.

In order to get a "reward", the anchor will try to get fans to "brush gifts". This is an online PK game between an anchor and another network anchor. The rule is to compare the number of gifts given by fans of the two sides within a specified time, and the loser will be punished by the game. Some fans keep giving gifts to support their favorite network anchors. On this network platform, the highest bid is the "Supreme Salute" with 66,666 coins, equivalent to RMB 9,523.

In recent years, some media have been speculating about this network female anchor’s "earning more than 5 million RMB a day at most" and other information about huge rewards. Among those who rewarded her, a gift from an account named "Laoye" exceeded RMB 80 million. Just as everyone was talking about the real identity of this person, the account quietly changed its screen name and disappeared from the network.

Although the authenticity of "huge rewards and profits" needs to be verified, the behaviors and propaganda of attracting netizens to "reward and profit" with this "routine" frequently appear on the Internet, impacting social psychology.

Netizen: Too high this amount may cause this vanity and comparison in society.

Netizen:Some anchors use some PUA (emotional manipulation) or even flattering means to earn rewards, which is also disrespectful to users.

Tong Lihua, Director of Beijing Youth Legal Aid and Research Center:In this way, there are tens of millions or even hundreds of millions of rewards, but how many real rewards are behind it, this information is not completely inaccurate. It is very harmful to the formation of minors’ outlook on life to create a false phenomenon of getting rich overnight for nothing in the whole society, especially among minors.

False means to hype "online celebrity" to induce netizens to consume.

In the investigation, the reporter found that some network anchors and platforms will use some false means to obtain "rewards", such as finding "trust" to pretend to be fans, forging anchor popularity traffic data, etc., to induce unsuspecting netizens to follow suit.

Xiao Wang, the post-95 s network anchor, told reporters that some anchors’ behavior of stimulating fans to reward through Lianmai PK is called "cheating tickets", which is called "cheating" because there are a lot of routines. For example, the operation team will pretend to be fans to brush gifts, create a tense atmosphere, and then defraud netizens to follow suit and reward.

Network anchor Xiao Wang:In fact, they are all people inside the company. We pretend we don’t know each other and then PK. Because several of my friends have four or five million fans in Tik Tok, they sometimes brush some gifts like this, and their active popularity is basically the same.

Traffic data fraud raises the psychological price of fans brushing gifts

In order to improve the popularity of the anchor and attract the audience, the live data will also be faked. Under the team operation, the number of real-time online users only needs to change the settings in the background, and all the traffic in the accumulated time period can be counted. In addition, there is a "multiple" operation, which can make the number of presenters 1000 times or even more than the real data, so as to increase the anchor price and raise the psychological price of fans to brush gifts.

There are vulgar phenomena such as sexual suggestion in many online platforms.

In order to increase the reward amount, some anchors attract users by revealing clothes, frivolous words, promising to give gifts "to welfare", and even seduce "reward" by means of sexual hints and soft pornography, resulting in bad information existing in the webcast platform.

On a live broadcast platform, the reporter randomly entered the "hot" section recommended by him, and found that it contained live broadcasts with sexual hints and induced users to reward.

The network anchor is scantily dressed and foul-mouthed, with only one purpose — — Let netizens recharge their rewards. Some anchors don’t show their faces, but aim the camera at a certain part of the body all the time, while others induce users to browse with exposed clothes through so-called sports display and game explanation, and then become so-called "fans". Xiao Wang, who has experience in webcasting, said that this kind of "soft pornography" is a quick way to get rewards for webcasting.

Network anchor Xiao Wang:The only income of the anchor depends on your face, but if you are not so beautiful and brilliant, you will broadcast live for 4 hours today, but there may be no income. Now that it’s live, it must be done in the most profitable way, right?

In order to maximize revenue, network anchors attract netizens’ attention through words and limbs. Through investigation, the reporter found that such a routine has become an industry rule and appeared in many webcast platforms.

Tian Feng, a researcher at the Institute of Social Development Strategy of China Academy of Social Sciences:Many platforms have contracts with MCN organizations, and MCN organizations will choose anchors that may bring potentially huge traffic and reward amount. As for how the anchors broadcast, there may be a tacit understanding and compromise between this platform and MCN organizations, which will make the anchors do some side-scratching, because their goal is simple, that is, to bring traffic and reward amount.

According to statistics, since 2018, the number of webcasting apps has continued to rise. At present, there are more than 240 webcasting apps in Apple system alone. When the reporter searches for the word "live broadcast" in the mobile APP store, he will see a large number of APP recommendations pop up. The sexually suggestive words such as "late night beauty", "private video" and "sultry" are directly included in the name of the app, and what’s more, the words "chat" are directly typed to induce users to download and use it.

The chaos of "rewarding" misleads young people and encourages bad social atmosphere.

In view of the problems existing in webcasting, experts said that the influence scope of "rewarding" webcasting has gradually expanded, which has led some minors to go astray and affected the values of young people. This phenomenon of money first and reward by comparison is easy to encourage bad social atmosphere.

The reporter’s investigation found that there are a large number of college students’ anchors on many online platforms. Some girls are scantily dressed and coquettish, "seeking rewards", and some college students broadcast live in the dormitory "in groups".

In the investigation of the ecology of webcasting industry, the Youth and Social Issues Research Office of China Academy of Social Sciences found that a large number of college students have a strong yearning to become anchors. Since the media hyped information such as "the anchor won a sky-high reward" and "the anchor became a shortcut to get rich" on the Internet, some young college students have formed a "deformed" view of getting rich by selling jokes and coquetry.

Netizen:It is inconceivable that online celebrity will become rich, which will make contemporary young students think that it is more profitable to be a online celebrity than to study hard.

Teenagers’ cognitive ability and self-control ability are weak, and they can’t stand the inducement of the anchor to "reward" and "seek reward". Driven by their vanity and comparison, they reward the anchor without stint. Not long ago, a 15-year-old boy from Nantong, Jiangsu, rewarded all the 80,000 yuan medical treatment money accumulated by his grandparents to a network platform anchor, and the single recharge amount reached 10,000 yuan one day.

In recent years, examples of using savings or even misappropriating public funds to reward anchors have often appeared. These reports are shocking, such as more than 2.5 million yuan for the dead husband, more than 100,000 yuan for the poor students’ loans, and 48.26 million yuan for the post-90s male cashier to reward the anchor 20 million a year. In order to maintain contact with the anchor, some netizens do not hesitate to "reward" beyond their financial ability, which has a negative impact on the family or society.

Grasping and managing the chaos of "rewarding" together urgently needs systematic rectification.

In view of the "reward" chaos in webcasting, the website platform should fulfill the main responsibility, strengthen the audit, and solve the bad phenomena and behaviors from the source. In recent years, the relevant state departments have successively issued a series of regulatory policies, and gradually formed a standardized governance system in the process of joint management.

We should improve the "youth model" and the anti-addiction function.

According to the requirements of the National Internet Information Office, many video platforms have launched "Youth Mode" and anti-addiction functions. In this mode, teenagers can’t watch the live broadcast, reward and recharge, and they will be forced to log off the line after 40 minutes of cumulative use every day, and they can’t log in from 10 pm to 6 am.

Sexual suggestion and other "edge ball" behaviors need to be continuously rectified.

In order to pursue traffic and attract attention, some network platforms use algorithm technology to push audio and video content that violates social public order and good customs to users; Some network platforms hide evils and practices, allowing anchors to spread sexual hints or pornographic information, and even luring users to engage in illegal transactions across platforms. In this regard, the national network information department has carried out many rectification and strict supervision.

Make concerted efforts to strengthen the standardized management of webcasting

On November 23, 2020, the State Administration of Radio, Film and Television issued the Notice on Strengthening the Management of Online Show Live Broadcasting and E-commerce Live Broadcasting, which strictly stipulated that underage users should not be rewarded and that it is forbidden to hint, seduce or encourage users to "reward" in large amounts. On February 9 this year, seven state departments jointly issued the Guiding Opinions on Strengthening the Standardized Management of Webcast, emphasizing that the Webcast platform should set a reasonable upper limit for a single virtual consumer product and a single reward amount; The newly revised "People’s Republic of China (PRC) Law on the Protection of Minors" will be implemented on June 1st this year. It is proposed that webcasting service providers should set up corresponding functions such as time management, authority management and consumption management for minors to use their services.

Microsoft and OpenAI prevent hackers in Russia and North Korea from using AI big model | Titanium Media AGI

(Source: The Verge)

With the rapid development of AI technology, hackers have begun to use large models to upgrade network attack technology.

Titanium media app February 15 news,Microsoft, an American technology giant, published a research article entitled "Staying ahead of threat actors in the age of AI" in official website last night.

Microsoft claims that their joint research with the OpenAI team found that hacker organizations in Russia, North Korea, Iran and other countries are using generative AI tools such as ChatGPT to conduct target research, improve scripts and help build social engineering skills, thus improving and perfecting existing cyber attack technologies.

"Cybercrime groups, national threat actors and other opponents are exploring and testing different AI technologies, trying to understand their potential value to operations and security controls that may need to be circumvented." Microsoft said in the article.

Microsoft emphasizes that the advancement of AI technology has increased the demand for network security and security measures. Microsoft should continue to cooperate with OpenAI, constantly improve its defense measures, identify, detect and prevent potential malicious use or abuse by hackers, and protect customers’ data security.

It is reported that,Since Microsoft invested billions of dollars in OpenAI in 2019, the two companies began to work closely together. Especially after the release of ChatGPT, Microsoft has become an important beneficiary of the new wave of AI. Its market value has surpassed that of Apple, reaching $3.01 trillion, making it the world’s most valuable technology company.

Microsoft revealed that the goal of its cooperation with OpenAI for this research is to ensure the safe and responsible use of AI technologies such as ChatGPT and adhere to the highest standards of ethical application to protect users from potential abuse.

As a part of the research, in 2023, Microsoft developed a product called "Microsoft Threat Intelligence", which tracked more than 300 cyber attackers, covering actors in 160 countries and 50 ransomware organizations, and collected more than 750 billion signals per second, which were synthesized by using complex data analysis and AI algorithm to understand and prevent cyber threats and criminal activities.

At the same time, by the end of 2023, Microsoft has recruited more than 10,000 security and threat intelligence experts around the world, including engineers, researchers, data scientists, network security experts, threat Seeker, analysts, investigators and frontline responders, and more than 15,000 partners have provided professional solutions. In the past 2023, Microsoft Threat Intelligence blocked an average of 4,000 hacker intrusion threats with identity verification every second, and 135 million managed devices provided security method service feedback.

In the research of Microsoft and OpenAI, it is mainly mentioned that the following four hacker organizations use AI model technology to improve and upgrade network attacks, which may pose a certain threat to the country.

  • Forest Blizzard (STRONTIUM), a Russian military intelligence technology (organization) connected with GRU 26165, threatens many fields such as national defense, transportation/logistics, government, energy, non-governmental organizations (NGOs) and information technology. It is found that they use the Large Model (LLMs) to "understand the satellite communication protocol, radar imaging technology and specific technical parameters".
  • Emerald Sleet (THALLIUM), a hacking technique (group) from North Korea, remained highly active in 2023. They use the loopholes in the research report published by the big model to help and draft the content of phishing activities, including impersonating well-known academic institutions and non-governmental organizations to lure victims to reply to expert opinions and comments on North Korea’s foreign policy.
  • Crimson Sandstorm (CURIUM) is a hacker organization from Iran. Since 2017, it has been active in many fields, including national defense, shipping, transportation, health care and technology. Microsoft said that they used a big model to generate phishing emails and even code to evade anti-virus software detection.
  • Charcoal Typhoon (CHROMIUM), whose organization also uses models for research, scripting, translation and improvement of existing tools.

Specific to the case, Microsoft revealed that some hackers use "voice imitation" and other methods to make AI synthesize speech. A three-second voice sample can train a model that sounds like a person, thus attacking and maliciously defrauding users of important private information. "Even your voice mail greeting can be used to get enough samples."

In fact, with the emergence of multi-modal AI model tools such as ChatGPT, it has not only helped more people to improve their productivity, but also been created by some lawless elements to crack malicious emails and use AI technology to carry out cyber attacks. Officials of the National Security Agency have warned that hackers are using AI to make their phishing emails look more credible.

However, OpenAI also stressed that it found that the GPT model only provided "limited incremental" functions for hacker organizations. Microsoft stressed that they have not detected any "major attacks" using the big model. At present, Microsoft and OpenAI have closed or frozen the accounts and assets of related hacker groups.

In fact, the recent fraud cases about AI technology are on the rise.

At the beginning of February this year, the Hong Kong police revealed that the financial staff of a local company had been defrauded by DeepFake (deep forgery technology). The other party claimed to conduct confidential transactions, invited to participate in a multi-person video conference, and finally accepted the instructions of the fake Chief Financial Officer (CFO). The parties remitted 200 million Hong Kong dollars in 15 times and transferred them to five local accounts. The parties asked the head office for verification five days later, only to find that they were cheated and reported the case to the police.

According to incomplete statistics, from 2020 to 2022, the number of domestic AI fraud cases totaled 5, and the number of AI fraud cases increased to 16 in 2023; At the same time, in terms of case amount, the amount involved in AI fraud will reach 4.3 million yuan in 2023 from at least 3,000 yuan in 2020. The fraud case disclosed by the Hong Kong police this time has raised the amount involved to 200 million Hong Kong dollars (about 182 million yuan).

So, how do we prevent and solve the problem of AI fraud?

Microsoft mainly summarizes two aspects: First, the company uses AI to deal with AI attacks, such as making the technology of protective wall (cyber attack) more complicated and using AI to strengthen information protection, detection and feedback; The second is to detect and help users identify vulnerabilities through AI-based network security tools such as "Microsoft Security Copilot", and finally stop hacker attacks by software.

A number of domestic security experts have summarized four methods: first, users can consciously guide each other to do some actions during video, such as shaking their heads or opening their mouths greatly, so as to find the flaws on the edge of each other’s face or teeth; At the same time, you can ask a few private information that only the two of you know to verify each other’s identity; Thirdly, try to avoid a large number of photos and videos of yourself or your family on the public platform to provide convenience for criminals; Finally, update and install security software in time to further strengthen the network security control at the source.

"We think this is an important study to expose hacker organizations trying to make early and gradual actions through AI and share with customers how we can stop and counter their cyber attacks." Microsoft said that in the future, it will further enhance the technical capabilities of the AI ​ ​ big model, thus helping them to use the model to collect information about technologies and potential vulnerabilities and find ways to avoid cyber attacks.

Moving away from blood clots is the best anti-aging drug.

  Editor’s note:According to the information provided by the International Society of Thrombosis and Hemostasis, in the United States, 100,000 to 300,000 people die of venous thrombosis every year, and the number of related hospitalizations exceeds 500,000. In Europe, 500,000 people die of venous thrombosis every year. In China, the situation of venous thrombosis may be equally severe. Professor Wu Weiwei, Director of Vascular Surgery, Chang Gung Hospital, Tsinghua, Beijing, stressed that "moving" is the most effective prevention and control measure to stay away from thrombosis. What are the benefits of moving? Let’s watch together.

  Sit still at home, be careful of blood clots staring at you!

  Thrombosis refers to the formation of thrombus in artery or vein, which is the root of three fatal cardiovascular diseases (heart disease, stroke and venous thromboembolism). Thrombosis can occur in blood vessels anywhere in the body, and the incidence of venous thrombosis is higher than that of arterial thrombosis, and the ratio between them can reach 4∶1. Among them, venous thromboembolism refers to thrombosis in legs and lungs, which is not as important as heart disease and stroke.

  In recent years, with the change of people’s eating habits and lifestyles, the incidence of patients with venous thromboembolism in the world is also increasing year by year, and the number of hospitalized patients with pulmonary embolism in China has increased by four times every year. When it comes to thrombosis, many people think it is the patent of the elderly, but it is not. Wu Weiwei said that pregnant women, sedentary office workers, business travelers who often fly long distances and patients who need to stay in bed for a long time are all high-risk groups of venous thrombosis. He said that when he was in Union Medical College Hospital, he treated more than 20 pregnant women with venous thrombosis in one year.

  There are three main reasons for thrombosis: including long-term hospitalization, surgery (especially hip, knee and cancer surgery) and long-term inactivity. Because deep venous thrombosis often originates from the deep vein of the calf, it can partially or completely block the venous blood flow. In most cases, patients have no obvious symptoms and are often easily ignored in the early stage of the disease. With the progress of the course of the disease, sometimes patients will have pain or tenderness and swelling in one leg, mostly starting from the calf, and the ankle joint and foot will be red or obviously discolored with fever.

  Terrible is that no matter whether the patient has symptoms or not, the thrombus may fall off, and the thrombus will pass through the heart and reach the lungs with the blood flow, thus blocking the pulmonary artery, which will lead to shortness of breath, chest pain and increased heart rate, and even sudden death due to pulmonary embolism, which is the most serious consequence of deep vein thrombosis.

  Exercise can reduce risks. Anyone will be at risk of thrombosis because of sedentary, that is to say, deep vein thrombosis and pulmonary embolism can happen to anyone at any age. In fact, the risk of deep vein thrombosis increases by 10% for every hour of sitting, and the blood circulation of your knee joint decreases by 50% for sitting for more than 90 minutes. But this does not mean that venous thrombosis cannot be prevented. Wu Weiwei suggested: "The key to stay away from venous thromboembolism is to take effective preventive measures and increase exercise, which can effectively prevent the formation of venous thrombosis."

  Wu Weiwei also reminded that many seriously ill patients need to stay in bed for a long time after surgery. It is best for family members to massage their legs every three or four hours for 30 minutes at a time; Or massage every two hours for 15 minutes. You can also use a special inflatable massage chair instead of manual massage to promote blood circulation and reduce the probability of thrombosis.

  Sitting for a long time, driving or flying will bend the knee joint, which will lead to poor blood circulation. It takes a little time to stand up, walk and stretch your legs. If it is inconvenient to stand up and move at work, there is another hidden method, that is, "hooking your feet." For office workers, you should remind yourself to "hook your feet" every 90 minutes. The method is to straighten the foot and hook the whole foot up 10 times. There is no strict requirement on speed and rhythm, which can promote blood flow in the legs.

  In addition, it is suggested that high-risk groups should pay attention to the prevention of venous embolism, especially those with obesity, history of varicose veins, diabetes, long-term inactivity and long-term hospitalization. Pay attention to drink plenty of water every day, because if the blood is short of water, it will make the blood sticky. You can also buy a massage chair that massages your calves and wear varicose socks.

  Exercise is the best anti-aging drug.

  Henry lodge, an American doctor of medicine, and Chris Crawley, a lawyer who is over 80 years old but looks like a middle-aged man, don’t think so. They point out in their book Younger Next Year that insisting on exercise can fight against aging.

  The brain is more energetic. The book believes that only exercise can make the brain send a growth signal to the body, which is beneficial to sports ability, thinking activity and emotional control. A study found that the brain of people who keep exercising for three months keeps growing, and the new part is not only the area that controls movement, but also the frontal cortex (the complex thinking activities of human beings are controlled by the frontal cortex).

  Cardiopulmonary function is enhanced. Everyone who insists on exercise will generally go through the process from "panting" to "a piece of cake", because exercise improves heart and lung function. Su Hao, an associate professor at the School of Sports Science, Beijing Sport University, said that people with good cardiopulmonary function will not feel tired easily and will not get cardiovascular diseases easily. Long-term regular exercise can increase the weight and volume of the heart, slow down the heart rate when it is quiet, and thicken the ventricular wall of the myocardium, making it strong and powerful every time it contracts.

  The bones become strong. After people reach middle age, the amount of bone calcium is constantly losing, and the effect is not good only by eating calcium tablets. If you don’t exercise for a long time, the demand for calcium in bones will also decrease, and a large amount of calcium will be excreted through urine. Doing more outdoor exercise can increase the elasticity and toughness of bones and improve or alleviate the symptoms of osteoporosis.

  Relieve stress. Studies have shown that exercise is as effective as drugs in treating anxiety and depression. It can generate energy, stimulate optimism and help maintain a positive attitude towards life. This is because exercise promotes the body to synthesize serotonin and dopamine, which are brain chemicals that determine happy mood, thus helping to improve depression and relieve stress. Exercise can also reduce cortisol content, help improve memory and concentration, and improve work efficiency.

  It’s about persistence. Only by persisting can exercise be meaningful. In addition to regular square dancing and cycling, the elderly can also do some strength training.

  People who love exercise are 30 years younger.

  To what extent can exercise make people "grow backwards"? Sports scientists at Bauer State University in the United States say that the muscle strength of the elderly who insist on exercising is no less than that of young people.

  The researchers selected 28 elderly people over 70 years old as the research objects. Participants have been exercising since the 1970s, and researchers hope that through them, they can examine how sports can resist the decline of physical function caused by aging. The scientists tested the aerobic endurance of the participants and measured the number of capillaries and enzymes in their muscles. The analysis results show that compared with their peers who don’t exercise much, those who exercise regularly are at least 30 years younger in physical age, and the best ones are even comparable to those in their twenties.

  The researchers said that although these research objects are not athletes, they have already incorporated fitness into their daily lives and regarded exercise as a hobby. Participants have strong aerobic endurance, and the number of capillaries and enzymes in muscles is more than that of their peers who do not exercise. This means that they have effectively resisted the effects of aging on their bodies. Experts pointed out that the elderly can completely reserve healthy physical fitness through sports and effectively delay the aging process of the body.

  Skipping rope in 135 for easy fitness.

  In fact, it doesn’t take a lot of time to exercise. The "135" skipping method, which takes less than 10 minutes a day and is equivalent to running for half an hour, can achieve good fitness results. Gou Bo, a professor of sports medicine in Xi ‘an Institute of Physical Education, introduced the specific methods.

  "One" is 1 minute, that is, after a simple warm-up, jump rope as fast as possible for 1 minute; "Three" means 30 seconds, jump quickly for 1 minute, rest for 30 seconds, and then repeat; "Five" means repeating it five times, which is equivalent to exercising with high intensity for five minutes every day.

  Research shows that jumping for 5 minutes at the speed of 140 times per minute is equivalent to running for half an hour, which is a time-consuming and energy-consuming exercise method, and can also avoid the excessive burden on knees and ankles caused by long-term running. Skipping rope has a good promoting effect on heart and lung function, and it is also helpful to improve physical coordination and lose weight, and at the same time improve the muscle strength of lower limbs, making the body fit and agile. For office workers, skipping rope can also relieve backache.

  Gou Bo reminds that skipping rope should pay attention to the following points:

  1. Do warm-up exercises before skipping rope and do some relaxation activities after skipping rope. Shoes with soft texture and light weight should be worn, and the soles should have a certain thickness and be relatively soft. 2. It is suggested that when you start exercising, you should use the single-shake jump method, and your feet should rise and fall at the same time. Jumping does not need to be too high to avoid joint strain. 3. During skipping rope, you should keep your body relaxed moderately, and your toes and heels should coordinate their efforts to prevent sprain. 4. strenuous exercise is not recommended before meals and within 1 hour after meals. The best time for skipping rope is from 3 pm to 8 pm. 5. It is recommended to skip rope 4~6 times a week. (People’s Health Network is integrated from People’s Daily Overseas Edition and Life Times)

Why did the American president’s car change from Lincoln to Cadillac?


I believe that everyone’s circle of friends was screened by this picture a few days ago. Yes, for this position, two groups of people represented by Trump and Hillary Clinton have been blackmailing each other for nearly 10 months. In several public debates, two prominent high-level people ridiculed and attacked each other, and many scandals were exposed in succession, and this is the position they are vying for-the back seat of Cadillac No.1, which only the President of the United States can sit on.

Yes, now, the American president’s car is a special Cadillac, but in fact, the American president’s love for Cadillac is only in recent decades. If you turn to history, you will find that earlier, brands such as Lincoln were the favorite of the American president, and they all dominated each other for decades. So, what made the change happen? Next, let’s follow Rut Jun and enter the evolution history of the American president’s car to find out.

The President’s First Car-—1909 White Steamer

Of course, when Karl Ben Ci and gottlieb Daimler won the patent right of the world’s first automobile in 1886, the first 20-odd American presidents had no access to automobiles, and they only went out by carriage, and they never drove a car. Until the 25th President William McGinley test-drove Stanley in July, 1901 (it was formally established in 1902, but the first car was built in 1887, an American manufacturer that only produced steam cars. By the early 1920s, cheaper gasoline cars reappeared and gradually occupied the steam car market, and Stanley went bankrupt in 1924).

William McGinley test drive Stanley.
According to the regulations of the Secret Service, the president’s carriage needs bodyguards to follow at all times. After the gradual popularization of cars, the Secret Service specially bought White Motor’s steam car as a escort in 1907. However, Theodore Roosevelt, then president, would rather take a carriage than a car because he wanted to maintain his "rough knight image."

After Theodore Roosevelt refused to run for re-election, William Howard Taft, the 27th president who was hand-picked by him, turned a new page in the White Motor. The original stable was turned into a garage. In 1909, he spent $12,000 (equivalent to $310,000 now) to buy four cars, including two luxury cars, Pierce-Arrow (an American luxury brand, the car of many celebrities), and bought a representative to enter the upper class, and at the same time produced trucks and fire engines.

The first official presidential car-White Steamer

White Motor is a shady American automobile manufacturer, whose products cover trucks, tractors, bicycles, roller skates and sewing machines. Thomas•White, the founder, originally bought a steam car company in Locomobile, but found that the steam engine is extremely dangerous, because the water in nature is soft, and it is easy to form scale on the boiler wall when heated, which will lead to uneven heating and boiler explosion. However, his son Rollin•White made a great improvement, which greatly reduced the probability of explosion. White’s steam car gained good sales, but when the gasoline car gradually counterattacked, White’s center of gravity began to shift, instead of stubbornly hanging himself from a tree. It turns out that they did the right thing.

Although Pierce was originally the president’s official car, when the "engine" of the steam car was running, the thick steam just helped to block the reporter’s camera and questioning. This seven 40-horsepower White Motor became his favorite. Did it have its own destiny with the White House? In fact, this large convertible laid the tone for more than 60 presidents to drive later.

Taft and his family are sitting in White Steamer.

The White House’s First Bulletproof Car-—Packard Twelve Rollson Phaeton


Franklin Roosevelt, one of the most outstanding presidents in American history and the only one who held the presidency for four consecutive years, took over Hoover’s mess during the Great Depression in 1929, and then quickly introduced a series of practical measures to save the country. Therefore, when he ran for the 38th president in 1936, he won 523 of the 531 voter votes, and assumed the post with a super high proportion. But at this time, his car was still a large convertible. At that time, most leaders liked to stand in the convertible and wave to the masses. As the saying goes, there was no shelf to narrow the distance with the masses and improve their support rate. Even Hitler still stood in the Mercedes-Benz convertible after the outbreak of World War II.

Hitler and his Mercedes 770K

In the 1930s, there was a "cylinder number war", and all luxury brands in the United States were gearing up for the top spot. Eight cylinders just came out here, and 12 cylinders were immediately launched there. Cadillac with 16 cylinders finally won the war without smoke, but Packard is still an important part of the American luxury car puzzle. You know, behind Cadillac is GM, behind Lincoln is Ford, and Packard is just an independent luxury car manufacturer.

In 1932, the sales of luxury cars reached 22,000 units, of which 35.6% were Packard and only 16.9% were Cadillac. On the one hand, the price was 500-1,000 dollars lower than that of competitors, and at the same time, it provided luxury as other brands. On the other hand, many versions are derived from a single product line, which greatly reduces the expenses of updating or launching new models from time to time.

Twin Six with graceful atmosphere

As an independent brand, it will not be influenced by other brands under the group, and it does not need to share the losses. In addition, its working method is very flexible, and even it has been transferred to others as a beer production line.

Two years after the end of the Great Depression in 1933, Packard introduced the entry model 120 with a price of less than $1,000, and the sales volume doubled continuously. The reason is also simple. The advanced degree of 120 configuration not only exceeds its own high-end series, but also uses large-scale modern production technology. Under the same labor force as high-end models, the output can be 10 times higher, and high efficiency is not equal to money. However, this move has somewhat affected the brand image.

Packard 120 Coupe

By 1939, Roosevelt customized Twenty Rolls on Phaeton, claiming that the reason for choosing this brand was its reliability and strong power. At this time, many luxury brands founded at the same time had closed down before 1938, and Roosevelt invisibly made a wave of strong advertisements for Packard.

Packard Twelve

Twelve series can be said to represent the highest technological level of Packard. In the 1930s, it was equipped with controllable hydraulic suspension control system and hydraulic brakes, and the natural price was not cheap. The initial price was from $3,650 for a Coupe to $4,395 for a Sedan (now $150,000-$170,000), and then with some customization, the price could rise to the level of Rolls Royce.

The biggest highlight of Rollson is that it is the first American presidential car with bullet-proof body and glass. In 1939, it happened to be the time when World War II broke out. After the Pearl Harbor incident in 1941, the United States announced its participation in the war, and Roosevelt’s other cars were also equipped with bullet-proof armor and glass, which only slightly improved the safety awareness. The problem is that these cars are still convertible models.

Lessons of Blood-Lincoln Continental SS-100-X

Therefore, a lot of progressive reforms need bloodshed. On November 22nd, 1963, at about 12: 30 noon, the 35th President of the United States, John Kennedy, accompanied by his wife Jacqueline Kennedy and Texas Governor John Connery, was assassinated by Lee Harvey Oswald in a Lincoln convertible as he drove past Dallas’ Dilly Square. So far, there is no accurate and convincing statement about this incident, and the related witnesses have died strangely, adding a lot of confusing atmosphere to this case.

Before Kennedy took office in 1961, the Secret Service rented the fourth-generation Lincoln Continental convertible from Ford at a price of $500 a year. The biggest reason for choosing the convertible was to let the enthusiastic people see the leaders they supported with their own eyes. In a sense, it was the same as a star meeting, and then fans were more willing to canvass for their idols. At this time, the American car design style is no longer the grandiose aviation style in the 1940s and 1950s, but the "design obeys the function", and the mainland has also changed into a wedge-shaped design (many people think that the aura and feeling of luxury cars are not as good as those in the past, and it is not unreasonable. After so many years of development, car design is now focused on fuel economy or performance, and the previous unrestrained style can only be said that manufacturers all over the world have tried and tried with Americans).

At that time, the car was priced at $7,347 (now $58,000), equipped with a 350-horsepower 7.0L V8 engine (this is only the minimum engine), which was 104 centimeters longer than the original length of 5.4 meters, and then handed over to Hess & Eisenhardt (a refitting factory that provided driving safety for world leaders and served every American president from 1948 to 2001). Including many government agencies in the United States, code-named SS-100-X, but the modification cost of $200,000 (now $1.587 million) only upgraded the comfort configuration, and the safety measures were only handrails for bodyguards to grasp in the trunk, while the so-called double-glazing could be installed in dealers.

This Lincoln has also become the last convertible in the history of the American president’s car. Since then, there has never been such a situation in the United States where the president is sitting in a convertible. After the assassination, Vice President Lyndon Johnson was on the verge of death on Air Force One, and this car continued to serve Johnson until 1967, but it was tempered with a bulletproof roof and thicker armor. The original car was painted black from dark blue, and the "high power" mode could be started in an emergency. The engine will generate more than 17% of the power, and it was not until 1978 (later as a security vehicle) that it retired to hometown and was housed in the Ford Museum in dearborn, Michigan, and quietly accepted the attention of everyone.

Learn from one’s mistakes-Cadillac Fleetwood Brougham

In 1981, Ronald Reagan, the 40th president, just took office for 69 days. Just after giving a speech and eating, John hinkley suddenly rushed out to attack Reagan. Although he was shot in the abdomen and lungs, fortunately, he did not pose a threat to his life and recovered quickly, but it is estimated that he has formed a huge psychological shadow on Lincoln.

Lincoln, as the standard of the president, can be traced back to Franklin’s time. As for the reason, it must have something to do with the name "Lincoln". Every president hopes that his achievements in office can reach the height of Abraham Lincoln (however, Lincoln himself was assassinated).

Lincoln’s fifth generation continent at the time of Reagan’s assassination

Although Lincoln mainland had a bulletproof body and roof at this time, after the assassination, he directly replaced it with Cadillac Fleetwood Brougham (the "Fuehrer’s open-top carriage", but Cadillac’s rear roof was changed to leather), and Ice cancelled the roof skylight to ensure all-round safety protection.

This car is equipped with a 135-horsepower 4.1L V8 engine, which is 430 mm longer and 76 mm higher than the original car. It is equipped with armor and bulletproof glass with a thickness of 60 mm. The huge glass area is like a mobile greenhouse. In order to withstand such a large weight, the tires and wheels have of course been upgraded.

At that time, many people thought that the presidential car in a 1993 movie "Sniper by Firewire" (also the story of the assassination of the president) was the original car, because the model made in the movie was so elaborate, but when you think about it, it is impossible. As a state secret, every presidential car is either taken back to the museum or completely destroyed after retirement, and it is impossible to borrow it as a movie prop.

Trembling-Cadillac One

In the next 30 years, only George H.W. Bush chose Lincoln, and all others were Cadillac. Obama’s Cadillac One-"The Beast" was also brought to China during the G20 Summit in Hangzhou some time ago. Later, the media basically interpreted everything that civilians could know, such as the modeling based on DTS, the grille of CTS and the headlights of Escalade. In terms of power, there is no specific data on the weight of 8.1L V8 gasoline engine or 6.6L turbocharged V8 diesel engine, but it is definitely not light from the Goodyear RHS tire, because this type of tire is usually used for medium and heavy trucks. The safety measures are undoubtedly the best in the past. The 55mm bullet-proof glass (only the main driver can lift it to pay the toll), the steel plate of the car body is 127mm thick, and there is no keyhole in the whole car. Even how to open the door is a secret.

In addition, it is equipped with tear gas throwing equipment, shotguns and other weapons. When attacked by howitzers or anti-tank missiles, the car can also launch multi-spectral infrared smoke bombs to interfere. Even if the president is attacked, the oxygen supply system, fire extinguishing system and the president’s exclusive blood reserve are all available.

The above interpretation seems to have narrowed the distance between the American president’s car and the Chinese people, but this situation is not expected to happen in the future, because Trump’s new car will be unveiled at the inauguration ceremony on January 20 next year, and the "beast" will become history.
