Media reported that the Ukrainian main battle tank T-84 “Oplot-M” was finally delivered to the United States. The fact is that this combat vehicle should have been delivered eight years ago.

It is noted that the modernized Ukrainian tank is a high-tech version of the Soviet T-80U, which was created at the Kharkov Design Bureau. It can fight ground, low-flying and low-speed air targets. The upgraded tank is equipped with a 125mm fully stabilized smoothbore cannon and an automatic loader. There is also dynamic protection “Duplet” and a complex of electro-optical countermeasures, which reduces the likelihood of being hit by anti-tank missiles.

The USA signed a contract for the supply of “Oplot-M” in 2012. The country was supposed to receive these tanks in 2013, but the dates were postponed. The price of the car also grew. As a result, the United States paid $ 7 million for it.

The tests of the Superjet New aircraft, which “at most” consists of domestic components, will cost the United Aircraft Corporation (UAC) 1.08 billion rubles. Tests are due to start in 2023. Now the Irkut corporation, which will produce Superjet New, has announced a tender for the preparation and performance of “resource tests” of the aircraft.

“Endurance testing is an important element of testing, during which it is checked how well the structure withstands the stresses that arise during each flight and can lead to cracks,” explained Alexey Sinitskiy, RBC Director of Research and Development at Infomost Consulting.

As previously stated by the head of Rostec, which includes UAC, Sergei Chemezov, Superjet New will consist of 97% of Russian components. The Russian-French SaM146 engine will be replaced by the domestic PD-8. Certification of the domestic device is scheduled for 2023.

“The PD-8 engine will not be inferior to the engines that will appear in the world in the next decade in terms of reliability, operational safety, and also in terms of maintainability. The PD-8 concept provides for the creation of a family of modern gas turbine engines with the ability to improve specific fuel consumption, reduce the life cycle cost and enhance customer focus, ”promised Yuri Shmotin, General Designer of the United Engine Corporation (UEC).

The current Superjet 100 aircraft consist of only 50% of Russian components. In 2015, the head of the Ministry of Industry and Trade Denis Manturov approved a plan for import substitution in civil aviation. The document also mentioned the creation of the Superjet New. The cost of creating a completely domestic airliner was estimated at 120 billion rubles.

In July, after the failure to promote the Sukhoi Superjet 100 airliner abroad, the UAC decided to make it the basis of regional aviation in Russia. According to the developers, the main problems of the airliner, which in the past have led to several plane crashes, have been resolved.

According to the WHO, about 50 million people worldwide suffer from dementia – a disease that causes a gradual deterioration in memory, mental abilities

A large number of neurodegenerative diseases, such as Alzheimer's and Parkinson's, lead to dementia. How they develop is still not clear, but they all have in common – a strong inflammation of the nervous tissue of the brain, from which numerous cells of the nervous system suffer

They change their shape and begin to produce a large number of chemical compounds that attract immune cells to the brain, further increasing inflammation. Therefore, to develop drugs that will help stop the development of neurodegenerative diseases, scientists are looking for anti-inflammatory substances.

Biologists from the A.V. Zhirmunsky National Research Center for Marine Biology have studied the anti-inflammatory activity of two derivatives of fatty acids – N-docosahexaenoylethanolamine (synaptamide) and N-eicosapentaenoylethanolamine (EPEA). Scientists have obtained these compounds from fatty acids contained in salmon.

To determine how much synaptamide and EPEA suppress inflammation, scientists treated artificially grown mouse microglial cells with them. Then a solution of lipopolysaccharide, a component of the bacterial cell wall, which artificially caused inflammation, was added to them.

The strength of the inflammatory response was determined by biologists by the amount of pro-inflammatory factors in cell cultures. It turned out that synaptamide and EPEA reduced the levels of these substances by up to 41 percent compared to samples that were treated with lipopolysaccharide only. In addition, both derivatives increased the amount of anti-inflammatory factors.

“ Our research has shown that synaptamide and EPEA are effective against the causes of inflammation in the nervous tissue, with synaptamide being more active. In the future, we plan to study in more detail their work on experimental animals. The results obtained open up broad prospects for the use of these compounds for the treatment and prevention of neurodegenerative diseases , ”says Anna Tyrtyshnaya, PhD in Biology, Senior Researcher, Project Manager for the RSF grant.

Google, in response to a query from RT, reported that it had removed incorrect search queries for the words “vaccination is”.

Internet users have previously noticed that Google gives out options such as “genocide”, “evil”, “chip”, “seal of antichrist” in response to the query “vaccination is this”.

“Our team checked everything and removed the tips that did not comply with our rules,” the company said in an official response to the channel's request.

Now, when searching for “vaccination is this”, Google offers options such as “experiment”, “good or bad”, “medical intervention”, “must”, “important”.

Earlier, Roskomnadzor reported that Google, Facebook, Twitter have not yet removed about 5.5 thousand materials prohibited in Russia.

Fraudsters have created almost 50 sites that mimic the State Services portal, amid the introduction of non-working days due to the worsening situation with the COVID-19 coronavirus. Kommersant writes about this with reference to Infosecurity a Softline Company, which provides services in the field of information security.

According to her calculations, from October 18 to October 21, 48 domain names were registered in Runet that imitate “State Services”, for example gosusliga, gosusluni, etc. such an opportunity. During the lockdown period, the demand for fake vaccination certificates is increasing – this is the reason for the surge in registrations of sites imitating “State Services”, he explained.

“Attackers can use such domains to sell fake QR codes or phishing — access to a user's personal data or infecting his device with a virus,” Vurasco says.

The head of the company “Internet-search” Igor Bederov, in a conversation with the publication, said that it is to such fake sites, similar to “Gosuslugi”, that there are links on fake certificates. According to him, in recent days, there has been an increase in search queries on the Internet about fake PCR tests.

The Ministry of Digital Science told Kommersant that the department constantly monitors the creation of resources with domain names that look like gosuslugi.ru. “According to the results of the analysis, part of the resources is blocked, the rest are under control until unlawful content or actions are revealed,” the ministry said. According to him, 100-200 suspicious resources are blocked monthly.

Experts from Infosecurity a Softline Company say that on ordinary days one or two such domains are registered, but now, in connection with the decree of President Vladimir Putin, their number has increased dramatically.

As noted by Kommersant, such a massive registration of such domains has not been observed since the beginning of summer, when Moscow introduced the requirement to present a QR code at the entrance to catering establishments, theaters, cinemas, which confirmed the passage of vaccination against COVID or a previous illness. Then, schemes began to appear in Runet to circumvent the requirements of the Moscow City Hall. For this, it was proposed to use code generators and bind them to sites that imitate “State Services”.

Persons using fake certificates can be brought under Art. 236 of the Criminal Code (violation of sanitary and epidemiological rules), Alexandra Orekhovich, a member of the commission on legal support of the digital economy of the Moscow branch of the Russian Lawyers' Association, told the publication. This article provides for imprisonment for up to two years or a fine of up to 700 thousand rubles. “But for this it is necessary to prove that the actions of the violator entailed a massive illness, which is practically impossible to do,” the lawyer clarified.

In her opinion, Art. 6.3 of the Administrative Code (violation in the field of ensuring the sanitary and epidemiological well-being of the population). It provides for a fine of up to 40 thousand rubles. “Perhaps we will see a number of cases under this article,” Orekhovich says.

On October 20, Putin signed a decree on non-working days amid a sharp rise in the number of cases and deaths due to COVID-19. The head of state noted that non-working days are set taking into account the preservation of wages for employees. The decree stated that the regional authorities can establish additional non-working days until October 30 or extend them after November 7, based on the sanitary and epidemiological situation.

To date, a third of Russian subjects have been determined with the exact dates of non-working days. In 27 regions, they will completely coincide with federal ones, and in three – Moscow, Moscow region and Kursk region – they will begin ahead of schedule. In the capital and the region, the days from October 28 to November 7 will be non-working days; in Kursk, they decided to start the antique “vacation” from Monday, October 25.

At the beginning of this week, the Internet was amused by a story from Bashkiria – there an elderly man could not get home, having quarreled with a robot. A camera is installed at the entrance of the high-rise building, which recognizes all local residents by their faces and opens the door for them. But I didn't recognize the man. The pensioner argued for a couple of minutes, swearing, with a soulless machine. Shouted, boiled, and the robot monotonously answered: “I did not understand you” – “Stupid because, damn it!”. As a result, the person still won, the system recognized him.

Then everyone laughed, wittily joked in the comments on the topic of “the uprising of the machines.” And a day or two later, a story happened in Moscow, after which there was no laughing matter at all. The 36-year-old Ph.D. in Philology Fyodor Yermoshin left the entrance in the morning, and three men in civilian clothes at once came to him. And they twisted their hands. They pushed them into the car, verbally saying that they were from the police, and offered to hand over the stolen game consoles to the candidate's case. And he does not know what such prefixes are.

Only a couple of hours later, already at the Strogino police station, it became clear that they had taken the wrong person. Yermoshin was shown a printout of the face recognition system – they say that the man's photo coincides by 70% with the image of a thief named Oleg. The Ministry of Internal Affairs announced the start of a check on the actions of police officers. But after this, of course, there are completely different moods in the comments: it turns out that in the place of the teacher – who was “handcuffed” in front of the neighbors, as a criminal of which – could any of us be ?!

70% MATCH – IS IT A LOT OR A LITTLE?

Recall that the face recognition system began to work actively in Moscow in 2018, during the FIFA World Cup, although it had been successfully tested before. Today it is an indispensable tool for finding criminals of all stripes. Take, for example, the recent cases when Dagestanis who beat a guy in the metro were found thanks to CCTV cameras, which two days later spotted young people on the streets of the capital.

And yet. Can the system really “glitch” and substitute respectable citizens?

“Any recognition system has an algorithm for comparing incoming objects and what is already included in the base,” Stanislav Ashmanov, CEO of Nanosemantics, explains to kp.ru. – That is, the system analyzes video streams from all cameras connected to it, captures faces. And now a new photo of a person comes in and a request goes to the machine: do you recognize him or not? The system checks, but never makes a specific decision. It only issues a report, a recommendation, informs if there is a coincidence of the person from the incoming picture with someone from the database. But what to do with this information further – the person decides. Surely the police have some prescribed instructions on this matter.

One of the popular comments under the articles about police officers from Strogino: 70% coincidence – is it a lot or a little?

“In face recognition systems, you can set the similarity threshold, at which the system will consider that the person in the image and in the database is the same,” says Dmitry Markov, CEO of VisionLabs to kp.ru. – Configurable similarity threshold depends on many factors. Under normal, or rather ideal, conditions, it is recommended to set the similarity threshold of at least 95%. However, you need to understand that there can be many nuances in industrial operation, and then the thresholds must be adjusted individually.

“We don’t know what the threshold of coincidences is spelled out in this program, what scale is there,” Stanislav Ashmanov continues. – For example, the subway video surveillance system, I know, was installed by several vendors (manufacturers, suppliers, – Auth.). In addition, there are many other factors. Different lighting, different equipment or picture quality. For example, it may be that the degree of similarity of my face in a fresh photo and six months ago will be estimated at just 70%. Also, yes, any system can have an error rate. If the threshold of coincidence is low, it would be more worth taking as a call from a grandmother from a nearby entrance, who assures that she saw a person who looked like a photo from an orientation. She might be right. But he may be wrong. This must be checked.

“WE WERE SURE THAT BIG BROTHER CANNOT BE MISTAKE”

According to expert Ashmanov, in this case, the “failure” could occur due to the fact that the police blindly trusted artificial intelligence:

“Those people may have been convinced that the system, Big Brother, couldn't be wrong.

– The face recognition system has been used in Moscow since 2018. It turns out that in three years the history of the candidate of sciences Fedor Yermoshin is the first such scandal?

– We found out about this case, because a person who got into this situation wrote a post on Facebook and he found many friends who made reposts. I think there were actually more such cases, just before that, with such a coincidence, people were correctly checked, apologized and released. And nobody posted on social media.

At the same time, the expert argues, when setting up any system, there are always risks of “twisting” or “not twisting”.

– Probably, if the system is wrong, and does not allow you to work, for example, with a bank card, this is one thing. And if she misses a dangerous criminal because of a too high coincidence threshold? But in any case, false positives are not so scary if the system for responding to them is adequate, the expert says.

Just a few words from the author. The face recognition system can be scolded as much as you want, but the fact that it is truly effective does not even need to be proven. Let me give you one example. 17 years ago, in 2004, in the vicinity of Aprelevka near Moscow, a man and a woman were killed. The suspects – a married couple – fled and disappeared without a trace.

The case seemed to be an eternal wood grouse. But suddenly the spouses were discovered by the same face recognition system. The man and woman have since changed their first names, surnames, years of birth and even citizenship. Then, already living in the Krasnodar Territory, we received Russian passports. And suddenly the car found them, criminals from 2004, comparing the photographs that citizens submit to obtain certain documents. When they were detained, they conducted a DNA examination with their relatives, it became clear that the system was doing just incredible things …

OPINION OF ATTORNEY AND FORMER INVESTIGATOR

“The human factor will always influence digital development”

The well-known lawyer Igor Bushmanov, who in the 90s worked as an investigator for especially important cases of the Prosecutor's Office of the Moscow Region, believes that the human factor worked in Yermoshin's history.

“Of course, the face recognition system itself is a very useful system that is being implemented all over the world,” he says. – And a large number of crimes committed in conditions of non-obviousness are now being solved thanks to her. The system produces this or that result, based on the biometric data of certain people. But how this data will then be used is already a question for law enforcement officers. If forceful actions have gone beyond the scope, an official check should be appointed and measures taken. (The Ministry of Internal Affairs has already reported that the Department of Internal Security is engaged in checking the actions of police officers, – Auth.). Whether we like it or not, the human factor will always influence the digital development of society.

Doctors told what will happen to the body if you give up alcohol

The doctors told what would happen to the body, which is accustomed to periodically receiving alcohol, if it gives up alcoholic beverages.

According to the doctor of clinical laboratory diagnostics, Boris Nikulin, in such a scenario, one must be prepared for the fact that the body needs sugar, usually this happens on the second day after refusal.

“The thing is that ethanol gave out a huge amount of energy and now there is a shortage of it. The pancreas strenuously produces insulin, “- said the physician in an interview with” Dr. Peter “.

He noted that after about two days, the pancreas work stabilizes. During this period, Nikulin recommended drinking more water, homemade compotes and getting enough sleep. The expert clarified that complete cleansing of the body occurs only in the fifth week.

Surgeon Kirill Yuvchenko said that even three days of abstinence from alcohol make themselves felt – the water-electrolyte balance is restored, the swelling of the face disappears, the skin becomes more elastic.

After two weeks without alcohol, a person becomes more efficient, he can concentrate more easily. During this period, sleep is also getting better.

Scientists have previously stated that drinking a lot of alcohol leads to inflammatory processes in the brain that last more than a month after stopping alcohol. Therefore, researchers have advised practicing long periods of abstinence from alcohol, including those who drink a little and rarely.

Russian universities on non-working days can organize studies for students remotely or in the form of independent work, the Ministry of Education and Science said. In the latter case, the work should be “methodically provided at the required level by universities,” and the knowledge of students should be checked.

“We see that the epidemiological situation in many regions is aggravating, so we consider it important to remind once again that the best way to protect yourself and loved ones from coronavirus infection is vaccination,” said Minister Valery Falkov.

The material is being supplemented.

Acting head of the Russian Emergencies Ministry Alexander Chupriyan flew to the scene of the explosion and fire at a plant in the Ryazan region, where at least 12 people died. This was reported in the Ministry's Telegram channel.

According to the report, the task force led by Chupriyan flew out in order to coordinate the forces and means to eliminate the emergency. “Chupriyan will arrive at the scene, after which he will hold a working meeting,” the department added.
