New chess engine: Fisherov 0.98c NNUE

Fisherov - UCI chess engine (NNUE)Rating JCER = 3542

Fisherov is a chess engine derived from Stockfish. Code has been added in various parts to achieve a different style, which becomes more evident by deactivating his neural networks (although this would cause him to significantly lose his strength but he would gain in aggressiveness, which would be interesting for human training or to make him compete against other non-neural chess engines).

For greater robustness and competitiveness, the use of a neural network must be left activated (as it already comes by default). The engine already has a network incorporated, although there is also the possibility of using another network from the UCI options.

This engine was developed by Luis Damin Primo and Andres Ivan Primo residents of the province of Crdoba, Argentina.

Meaning of the name: Fisherov = Stock"fish" + Fisch"er" + Kaspar"ov".

Hidden harms: the impacts of air pollution on the mind – AirQualityNews

Air Quality Newsreporter Chloe Coules investigates growing concern around the effects that air pollution can have on our brains and wellbeing, from mental health to memory.

Researchers have known for decades that high levels of air pollution can have a negative impact on respiratory and cardiovascular health, accounting for around 28,000 to 36,000 early deaths a year in the UK according to Public Health England.

However, the effects of air pollution on the mind are less well understood, and researchers have only recently started to discover the vast range of impacts that air pollution can have on the brain.

Air pollution is not something we immediately think of when asked about the factors that increase a persons risk of having problems with their mental health. However, there is a growing body of evidence that suggests that air pollution does make people more likely to experience mental health difficulties, says Dr David Crepaz-Keay, head of applied learning at the Mental Health Foundation.

We also know that physical and mental health are very closely connected, so it is likely that something known to harm peoples bodies air pollution also harms their minds,

A recent study published in the journalJAMA Open Network,found that exposure to air pollution in childhood and adolescence is linked to an increased risk of mental illness in adult life.

The study monitored adolescents across several decades, measuring their exposure to nitrogen oxides (NOx) and fine particulate matter (PM2.5) in the home between the ages of 10-18 years, and then assessed their mental health once they reached 18.

Although air pollution was found to be a weaker risk factor than other more obvious risks to mental health on an individual level, such as family history, they concluded that air pollution exposure is widespread across the world and is therefore likely to be a significant contributor to the global mental health crisis.

The mechanisms through which air pollution harms mental health are similar to the ways in which it harms physical health, according to Matthew Johnson, professor of atmospheric chemistry at the University of Copenhagen and co- founder and chief science officer at Air Labs.

He explains that air pollution leads to inflammation of the central nervous system, in the same way that it causes inflammation of the lungs, which impacts upon peoples mental functioning, and it also degrades the health of the nervous system due to its toxicity, which can lead to the development of mental health issues.

According to Matthew Johnson, how this manifests can vary due to a range of factors, for example men are more likely to have depression as the result of air pollution, while women are more likely to develop anxiety. Worryingly, he has noticed that the impacts of the pandemic on our mental health and the amount of time we spend inside may be worsening this issue.

Theres a whole range of effects from poor air quality things that range from simple irritation or a headache, all the way up to major depression and suicide there really is a lot of evidence all along that spectrum, and I think people have noticed it more since they have been spending time indoors, and the stress of the pandemic itself has been compounding these things so theres kind of an intersection of mental health issues right now, he says.

Air pollution and memory

As well as impacting upon our mental health, air pollution can have a dangerous impact on our memory, in some cases even leading to the onset of Alzheimers disease.

Dementia and Alzheimers disease is the leading cause of death in the UK, accounting for 12.4% of all deaths registered in 2019. This problem is predicted to get much worse, with the World Health Organisation estimating that the global number of deaths from the condition will increase by over 40% between 2015 and 2030.

A recent study, published by the American Academy of Neurology, found older women living in areas with high levels of air pollution may be more likely to develop dementia.

The researchers examined hundreds of women who did not have dementia at the start of the study and found that for each 3 mg/m3 increase in PM2.5 exposure, there was a greater extent of brain shrinkage over five years, which was equivalent to a 24% increase in risk of Alzheimers disease, even after adjusting for a range of risk factors. Worryingly, the study found that air pollution still caused shrinkage of the brain in women exposed to levels lower than those considered safe by the US Environmental Protection Agency.

In addition, researchers at the Karolinska Institutet in Sweden have found that long-term exposure to PM2.5 and nitrogen dioxide (NO2) is associated with a higher risk of dementia, with heart disease and heart failure found to enhance the link between air pollution and dementia.

Although the researchers could not draw conclusions on why this occurs, they hypothesised that ultrafine particles may reach the brain via circulation and induce systemic inflammation, damaging the blood-brain barrier.

A global study published in the Journal of Alzheimers also found that people are more likely to develop dementia if they are exposed to PM2.5 and NOx over a long period of time. The research suggested that this may occur by increasing levels of inflammation in the human body, or by increasing the risk of having a stroke, as people are fifty times more likely to develop dementia in the year after a major stroke.

A study published in BMJ Open found that living in one of the areas of London with the highest levels of NO2 pollution was associated with a 40% higher risk of dementia than living in one of the least polluted parts of the city.

Air pollution and cognition

The inflammation that air pollution can cause in the body not only increases the risk of mental health issues and memory loss, but it also can hamper our cognition and decision making.

A study by researchers at the IZA Institute of Labor Economics measured the indoor air quality at chess tournaments in Germany and used a chess engine to evaluate how optimal each players moves were. They found that higher levels of air pollution impacted upon the players strategic decision making, especially under time pressure and stress.

According to one of the researchers, Steffen Knn, this effect on cognition is triggered by air pollution levels that you would see in any urban area or city in Europe and occurs within a few hours of exposure.

You go to work, going through rush hour with your bike, you inhale all the pollutants, your cognition will be impaired in the next few hours. This is the conclusion from our study, he tellsAir Quality News.The researchers found that different types of pollution have different levels of impact on cognition, with CO2 only significantly affecting decision making when the players were under time stress, while PM10 had a much greater effect regardless of time pressure.

What can be done?

Emerging research shows a clear link between air pollution and negative impacts on the brain, ranging from issues with mental health and memory to hampered cognition. However, the good news is that the research consensus suggests that limiting air pollution exposure can prevent or limit the effects that air pollution has on the mind.

Matthew Johnson advises that people be aware of their surroundings and take action to prevent exposure to air pollution if they are concerned about its impacts on their mental wellbeing.

He suggests that people identify specific sources of pollution that they encounter on a daily basis, such as poor ventilation when cooking, second-hand smoke, or rush hour congestion, and take measures to reduce the impact of the sources of air pollution, which could be as simple as opening windows or investing in personal air filters for the car or home.

However, the burden of mitigating the effects of air pollution cannot rest solely on the individual, and the only way to halt the rising impact of air pollution on the mind is to create lasting global change to tackle pollution at its source.

Good morning! If youre enjoying a holiday, please continue to enjoy it while we peek at wild new cars.

Motor shows are back

Car shows are back! Germany is playing host to fun new ideas at the 2021 IAA Mobility Event in Munich. It officially starts tomorrow but just like tech conferences, much of the good stuff is announced in pre-event launches.

And at the top of the list nowadays are electric vehicle and autonomous driving details and concepts, with the likes of Mercedes-Benz, VW, BMW, various startups, and so on, spilling out new concepts:





Pixel 3 phones are bricking left and right, no clear answer as to why, and the mode the phones fail into means theres little that can be done for now (Android Authority).

Phone makers may be forced to provide seven years of updates in Germany, two years longer than the EUs proposal (Android Authority).

Vivo X70 series specs leak: Three chips from three chipmakers (Android Authority).

Mark Gurman suggested Apple might announce its next major event as soon as this week, and suggested the coming Apple Watch Series 7 will be in tight supply which added weight to previous rumors (Bloomberg).

Apple quietly postponed its CSAM scanning initiative on Friday night heading into a holiday, saying: we have decided to take additional time over the coming months to collect input and make improvements before releasing these critically important child safety features. (Android Authority). Over 100 policy and rights groups, including the EFF and American Civil Liberties Union, had asked Apple to recalibrate. One take said the issue was Apple trying to solve a problem like this inside the Apple Park vacuum while adhering to its annual iOS release schedule. iOS 15 is expected in the next few weeks. (TechCrunch).

Microsoft Excel continues to give gene scientists headaches: 30% of published papers contain mangled gene names, due to problems like SEPT4 (septin 4) and MARCH1 being automatically changed to 4-Sep and 1-Mar (Nature).

Dyson could be designing a robot vacuum helper thing that can climb stairs (Bloomberg).

A desk bike looks weird but per this review, having a desk bike is actually pretty great. Huh. (Ars Technica).

NASA starts flight testing with Jobys electric air taxi or electric VTOL aircraft (Engadget).

Sony to offer free Horizon Forbidden West PS4 to PS5 upgrade after criticism (The Verge).

The Perseverance rover on Mars confirms it has collected and stored its first rock sample, after initial problems (CNET).

NASAs helicopter on Mars, Ingenuity, has clocked up 12 flights and is going so well that its mission has been extended indefinitely, though the approaching Martian winter will be a challenge (ScienceAlert).

Where does the CO2 absorbed by trees end up? (r/askscience).

Monday Meme

Coders at Apple thought of this, back in the day, when writing and testing Apples chess engine that has been baked into MacOS for the longest time:

Or in text form:

// Paradoxically enough, moving as quickly as possible is

// not necessarily desirable. Users tend to get frustrated

// once they realize how little time their Mac really spends

// to crush them at low levels. In the interest of promoting

// harmonious Human Machine relations, we enforce minimum

// response times.

Threatningly yours,

The pursuit of Carlsens world cup rival in the chess engine is stopped – The KXAN 36 News

It enlightens The international sjakkforbundet (Fide) in a statement on Thursday.

the Background for the decision is that the government of Russia has ordered aviation authorities to put all the scheduled flights and chartered planes to and from the country on the ground from Friday. The country will stop all international flights as a measure to limit the infection of the koronaviruset.

For despite the fact that all sports events have been cancelled or moved as a result of virusutbruddet, started kandidatturneringen where eight players compete to get to meet Magnus Carlsen for the world CHAMPIONSHIP duel, as planned in the Russian city of Yekaterinburg on Tuesday.

The international sjakkforbundet writes in the statement that the tournament cant continue without there being guarantees that players and managers get safely home.

It came as a consequence of that the russians have finally tightened into how they handle this viruskrisen. And since it will no longer be possible to get out of Russia about a couple of days, then found out that one only had to cancel so that the participants going home to their country of origin, says Nrks sjakkekspert Torstein Bae.

He believes this is a serious decision, which clearly is significant for would no longer be competitive and for the world CHAMPIONSHIP cycle.

Why should would no longer be competitive to continue with her?

Bae is critical that the tournament was cancelled on an earlier date, and was not cancelled or postponed like all other major sporting events.

It is clear there is reason to ask about it, if one in all ought to have gone in once with this tournament, when all the other sports have cancelled all their. Why should would no longer be competitive to continue with her? It was not difficult to predict that someone either could be sick, or if it would happen any further which meant that you had to break, he says to NRK.

the Battle for who will be Carlsens world cup rival will continue at a later time. When will the results from the seven rounds so far conducted will be applicable when the parties resumed.

If you start from scratch again, so they will which is the best the way to react to it. At the same time, if one is to take off at the starting point they have now, so it will be very difficult to get with the worst way. Seen this way, itd be better now if we had had a zero and only deferred to a later time, says Bae.

Protested against the tournament

the Introduction to the say the least, been chaotic.

Earlier this week selected, Teimur Radjabov, who should participate, to withdraw from the tournament after having asked The international sjakkforbundet whether to move the tournament.

Also the former toppspilleren Vladimir Kramnik, who would have commented on the tournament, withdrew from the mission in protest.

I think it is a mistake to hosting the tournament for several reasons: Both for the reputation, legal and not least the human, he wrote in a statement.

5 best software to analyze chess games in 2019 –

This is a strong open source chess engine which is offered for free, and is available for both desktop and mobile platforms.

Stockfish has consistently ranked number one or near the top of most chess engine rating lists, and is one of the strongest open-source engines worldwide. It uses up to 512 CPU cores in multiprocessor systems, with a maximal transposition table size of 1 terabyte.

Features include an alpha-beta search, bitboards, great search depth because of more aggressive pruning and late move reductions, and support for Chess960, plus much more.

The program comes from the Glaurung, an open-source chess engine released first in 2004, and four years later, Costalba took over and renamed it Stockfish because it was produced in Norway and cooked in Italy Costalba is Italian, and Romstad (creator of Glaurung) is Norwegian.

Stockfish is powerful and much stronger than the best human chess grandmasters. Unlike most chess engines, it is open source (GPL License), so you can read the code, modify it, contribute back and use it in your own projects.

You can also run it anywhere, including Windows operating system and on your smart devices, so you can get world-class chess analysis wherever you are.

Chess Engines Chess Tech

Chess engines are the brains of any chess program. Most modern engines come as separate entities to be added to your favorite GUI (Graphical User Interface). This post is aimed at helping you get some free chess engines and prepare them to install in your favorite GUI. Ill cover the GUI installation in separate posts.

How do you know what engines are the best?

Here is a list of the top rated free engines.

Where can I get these engines? Well you can Google them by name. Komodo Chess Engine for example. Just Google Komodo and youll get a lot of links to the lizard.

Below are links to the current top three free engines. After you download them. You will need to unzip them. I recommend keeping them in their own folder. First I would make a folder called chess engines somewhere easy to find. Because you may want to use these engines in more than one program. Example c:chess enginesFire5


The engines will often come in 32 bit and 64 bit versions. They may have both versions inside the zipped file. If you have to select at the time of download you need to know which kind of computer you have. This is how you can tell

So there may be a x32 (32 bit) version a x64 (64 bit) version. Also you may see bmi2 and popcnt versions. These additional versions are compiled to take advantage of special features built into specific microprocessors. The speed gained by running these versions are small but feel free to try them. If they dont run just switch back to the plain version. The BMI version may require changing settings in your computer bios. If you you want to do that here is a thread on that topic.

Meet YU’s Incoming Class – Yu News (blog)

Yehudah Goldfeder of Monsey, New York: Intrigued by Artificial Intelligence

In the coming weeks, Yeshiva University will welcome hundreds of new students to its undergraduate campuses from across the United States and countries around the world.Meet the incoming class as they share in their own words what excites them about beginning their academic journeys at YU at this yearsOrientation.

Where are you from?

I am from Monsey, New York.

Why did you decide to come to Yeshiva University?

Many factors contributed to my decision. I am the youngest in my family, and I have four older siblings, all of whom attended Stern College for Women or Yeshiva College, as did my father. My mother is a graduate of YUs high school for girls as well. Thank God, all of them have successful careers in their various fields. Those who went to grad school all got in to the school of their choice.

But to be honest, none of that is the real reason Im going to YU. I feel that it is important to forge ones own path in life. In truth, the reason I chose YU is because it was the best option available. I am fully committed to living an authentic Torah lifestyle, with all that it entails, while at the same time being an active and important participant in the modern world. I think that in YU Ill be able to maintain a real, rigorous learning schedule. Additionally, I am firmly convinced of the importance, perhaps necessity, of having a bona fide mentor to guide me along my path, and YU boasts a wide array of roshei yeshiva and rebbeim who can cater to a large spectrum of students individual needs. I still want my secular education to be a priority as well, and I think that YU will be able to cater well to this dual need.

What are you looking forward to at YU?

I plan on studying computer science, which has long been a passion of mine. It started as a hobby when I was eight or nine, and developed over time into one of my favorite subjects. I particularly have an interest in artificial intelligence that is getting machines to behave like intelligent, rational agents. Ive done a lot of self-study on that topic, like programming a chess engine (that plays better than I do) in C++ and learning the basics behind machine learning and artificial neural networks. I was specifically motivated by the groundbreaking Alphago, the first program to do the impossible and beat an elite Go player.However, computer science is a wide field and I find many topics in it interesting and worthy of exploration. I am very excited to finally get a formal education so that I can further my knowledge and my goals.

I also enjoy math and look forward to furthering my education there too. Writing has always been a hobby of mine, and I have written several large manuscripts of novels. Ive always felt that I have potential to be a good writer, and I am excited to explore that subject as well. The extracurriculars also seem exciting. I havent decided on exactly what Ill do (although I have some ideas in mind), but I am certain that aside from studying, Ill have plenty of fun.

As Ive mentioned, as well, I am very excited to benefit from the rebbeim here. Having a kesher, a relationship, with a rebbi where I can ask questions outside of the gemara, whether on general hashkafa or my personal life, is very important to me. I am also part of the MasmidimHonors Program, and it is my hope that those in charge of the program will guide me to be the best Jew I can be. I would love to learn as much as I can, in all topics related to yahadut[Judaism].

What are you passionate about?

I enjoy reading a lot. There are various genres I read, although Ill admit I have a soft spot for epic fantasy. I also enjoy building things with my hands, such as wood models, and I have a brown belt in karate.

What are you hoping to do professionally?

Hard to say exactly. Obviously I feel it will be computer-related, but to be totally open and honest, that could change in three years from now. I could see myself in many different roles, which is one of the reasons I am so happy to explore different topics.
