LEEDS, United Kingdom (StudyFinds.org) An artificial intelligence system is capable of spotting whether someone will have a heart attack within the next year through a routine eye scan.

A team from the University of Leeds believes this AI tool opens the door to a cheap and simple screening program for the worlds No. 1 killer. Their tests find the computer can predict patients at risk of a heart attack in the next 12 months with up to 80% accuracy. The breakthrough adds to evidence that our eyes are not just windows to the soul, but windowsto overall healthas well.

Cardiovascular diseases, including heart attacks, are the leading cause of early death worldwide and the second-largest killer in the UK. This causes chronic ill-health and misery worldwide, project supervisor Professor Alex Frangi says in auniversity release.

This technique opens-up the possibility of revolutionizing the screening of cardiac disease. Retinal scans are comparatively cheap and routinely used in many optician practices. As a result of automated screening, patients who are at high risk of becoming ill could be referred for specialist cardiac services, Frangi adds.

The system could also be used to track earlysigns of heart disease.

The retina is a small membrane at the back of the eye containing light sensitive cells. Doctors have found that changes to the tiny blood vessels canhint at vascular disease, including heart problems.

Study authors used an advanced type of AI, known as deep learning, to teach the machine to automatically read more than 5,000 eye scans. The scans come from routine eye tests during visits to opticians or eye clinics. All of the participants are part of the UK Biobank, which tracks the health of half a million adults.

Deep learning is a complex series of algorithms that enable machines to make forecasts based on patterns in data. The technique, described in the journalNature Machine Intelligence, could revolutionize heart therapy, according to the researchers.

The AI system has the potential to identify individuals attending routine eye screening who are at higher future risk of cardiovascular disease, whereby preventative treatments could be started earlier to prevent premature cardiovascular disease, says co-author Professor Chris Gale, a consultant cardiologist at Leeds Teaching Hospitals NHS Trust.

The study identified associations between pathology in the retina andchanges in the patients heart. Once the system learned each image pattern, the AI could estimate the size and pumping efficiency of the left ventricle from retinal scans alone.

This is one of the hearts four chambers. An enlarged ventricle can increase the risk of heart disease. The computer combined the estimated size of the left ventricle and its pumping efficiency with data like age and sex.

Currently, doctors determine this information using an MRI (magnetic resonance imaging) or echocardiography scans of the heart. The diagnostic tests are expensive and are often only available in a hospital. The tests can be inaccessible for many people in countries with lesser health care systems. They also increase health care costs and waiting times in wealthy nations.

The AI system is an excellent tool for unravelling the complex patterns that exist in nature, and that is what we have found the intricate pattern of changes in the retina linked to changes in the heart, adds co-author Sven Plein of the British Heart Foundation.

A recent study discovered a similar link between biologicalaging of the retina and mortality. Those with a retina older than their actual age were up to 67% more likely to die over the next decade.

Senior Research Associate in Machine Learning job with UNIVERSITY OF NEW SOUTH WALES | 279302 - Times Higher Education (THE)

Machinery has amplified the workload farmers can accomplish, and technology has delivered greater efficiencies. Now, autonomy is poised to introduce new levels of productivity and fun.

Different than its technology cousins of guidance and GPS-enabled controls, autonomy relocates the operator to anywhere but the cab.

True autonomy is taking off the training wheels, says Steve Cubbage, vice president of services for Farmobile. It doesnt require human babysitting. Good autonomy is prefaced on good data and lots of it.

As machines are making decisions on the fly, companies seek to enable them to provide the quality and consistency expected by the farmer.

We could see mainstream adoption in five to 10 years. It might surprise us depending on how far we advance artificial intelligence (AI), data collection, etc., Cubbage says. Dont say it cant happen in a short time, because it can. Autosteer was a great example of quick and unexpected acceptance.

The NEXAT is an autonomous machine, ranging from 20' to 80', that can be used for tillage, planting, spraying and harvesting. The interchangeable implements are mounted between four electrically driven tracks.Source: NEXAT

The idea and philosophy behind the NEXAT is to enable a holistic crop production system where 95% of the cultivated area is free of soil compaction, says Lothar Fli, who works in marketing for NEXAT. This system offers the best setup for carbon farming in combination with the possibility for regenerative agriculture and optimal yield potential.

The NEXAT system carries the modules, rather than pulls them, as Fli describes, which allowed the company to develop a simpler and lighter machine that delivers 50% more power with 40% less weight. In operation, weight is transferred onto the carrier vehicle and large tracks and optimized so it becomes a self-propelled machine.

This enables the implements to be guided more accurately and with less slip, reducing fuel consumption and CO2 emissions more than 30%, he says. Because the NEXAT carries the implement, theres not an extra chassis with extra wheels. The setup creates the best precision at a high working width that reduces soil compaction on the growing areas.

In the field, the machine is driven horizontally but rotates 90 for road travel. Two independent 545-hp diesel engines supply power. The cab, which can rotate 270, is the basis for fully automated operation but enables manual guidance.

The tillage and planting modules came from Vderstad, a Swedish company. The CrossCutter disks for tillage and Tempo planter components are no different than whats found on traditional Vderstad implements.

The crop protection modules, which work like a conventional self-propelled sprayer, come from the German company Dammann. The sprayer has a 230' boom, with ground clearance up to 6.5', and a 6,340-gal. tank.

The NexCo combine harvester module achieves grain throughputs of 130 to 200 tons per hour.

A 19' long axial rotor is mounted transverse to the direction of travel and the flow of harvested material is introduced centrally into the rotor and at an angle to achieve energy efficiency. The rotor divides it into two material flows, which according to NEXAT, enables roughly twice the threshing performance of conventional machines. Two choppers provide uniform straw and chaff distribution, even with a 50' cutting width.

The grain hopper holds 1,020 bu. and can be unloaded in a minute. See the NEXAT system in action.

At the Consumer Electronics Show, John Deere introduced its full autonomy solution for tractors, which will be available to farmers later in 2022.Its tractors are outfitted with:

Farmers can control machines remotely via the JD Operations Center app on a phone, tablet or computer.

Unlike autonomous cars, tractors need to do more than just be a shuttle from point A to point B, says Deanna Kovar, product strategy at John Deere.

When tractors are going through the field, they have to follow a very precise path and do very specific jobs, she says. An autonomous 8R tractor is one giant robot. Within 1" of accuracy, it is able to perform its job without human intervention.

Artificial intelligence and machine learning are key technologies to John Deeres vision for the future, says Jahmy Hindman, John Deeres chief technology officer. In the past five years the company has acquired two Silicon Valley technology startups: Blue River Technology and Bear Flag Robotics.

This specific autonomy product has been in development for at least three years as the John Deere team collected images for its machine learning library. Users have access to live video and images via the app.

The real-time delivery of performance information is critical, John Deere highlights, to building the trust of the systems performance.

For example, Willy Pell, John Deere senior director of autonomous systems, explains even if the tractor encounters an anomaly or an undetectable object, safety measures will stop the machine.

While the initial introduction of the fully autonomous tractor showed a tillage application, Jorge Heraud, John Deere vice president of automation and autonomy, shares three other examples of how the company is bringing forward new solutions:

See the John Deere autonomous tractor launch.

New Holland has developed the first chopped material distribution system with direct measurement technology: the OptiSpread Automation System. 2D radar sensors mounted on both sides of the combine measure the speed and throw of the chopped material. If the distribution pattern no longer corresponds to the nominal distribution pattern over the entire working width, the rotational speed of the hydraulically driven feed rotors increases or decreases until the distribution pattern once again matches. The technology registers irregular chopped material distribution, even with a tailwind or headwind, and produces a distribution map.

The system received a Agritechnica silver innovation award.Source: CNH

As part of Vermeers 50th anniversary celebration in 2021, a field demonstration was held at its Pella, Iowa, headquarters to unveil their autonomous bale mover. The BaleHawk navigates through a field via onboard sensors to locate bales, pick them up and move them to a predetermined location.

With the capacity to load three bales at a time, the BaleHawk was successfully tested with bales weighing up to 1,300 lb. The empty weight of the vehicle is less than 3 tons. Vermeer sees the lightweight concept as a solution to reduce compaction.

In April 2021, Philipp Horsch, with German farm machinery manufacturer Horsch Machinen, tweeted about its Robo autonomous planter. He said the machine was likely to be released for sale in about two years, depending on efforts to change current regulations, which state for fully autonomous vehicle use in Germany, a person must stay within 2,000' to watch the machine.

The Horsch Robo is equipped with a Trimble navigation system and fitted with a large seed hopper. See the system in action.Source: Horsch

Chess.com is thrilled to announce the Chess.com Rapid Chess Championship, our most elite event ever. The first "RCC" debuts with a prize fund of $650,000. This 25-week extravaganza begins on February 12 and culminates in a dramatic finale on August 28. Only the best of the best will be playing: the top 100 in the world, the top 10 women, and the top 10 juniors will have a seat at the table.

With only the strongest players comprising the field and the slower time control, fans can expect nothing but high-quality chess. Many top GMs like Fabiano Caruana, Anish Giri, Hikaru Nakamura, Wesley So, Maxime Vachier-Lagrave, Levon Aronian, and more are expected to participate in this event regularly.

Participants will also be allowed to stream this event, under controlled (chat disabled, along with other stringent Fair Play requirements) circumstances. This will provide a unique opportunity to offer viewers rare insights into high-level play, especially thanks to the rapid time format. 10+0 is the most popular time control on Chess.com but is rarely used in top-level events. In this format, players will have more time to strategize their way to victory.

Who doesnt want to hear Nakamura discuss his thought process in a 10-minute game against the worlds best players? Speaking of Nakamura, here is what he had to say about the Chess.com Rapid Chess Championship: "Im hyped to play in this event constructed by Chess.com in a way that seems to meet many of the top 100 chess players needs. Its got a flexible schedule, zero commitment, and yet seems to be a surefire hit with both the top players and the fans. With no additional demands being made by Chess.com on the participants time, it really is an ideal fit for so many schedules."

Im hyped to play in this event ... a surefire hit with both the top players and the fans.

- Hikaru Nakamura

Junior players made big waves in 2021, and we are happy to provide a special opportunity for them to play against the best players in the world. Recently-crowned World Rapid Champion, GM Nodirbek Abdusattorov, and other top junior players will have a chance to shine against the world's elite on a more frequent basis. We look forward to more juniors entering the top 100 in 2022 and qualifying for the event.

The mixture of top-100 players, the best juniors, and the top female players in the world will create some truly exciting match-ups and provide incredible opportunities for the next generation to continue to hone their skills.

The $650,000 prize fund is the biggest that Chess.com has ever offered, and it will be distributed throughout the entirety of the event. The first 25 weeks of the event have $500,000 allocated, which equates to $20,000 on the line per week. The finals have a $150,000 prize fund as well as the title of 2022 Chess.com Rapid Champion.

Chess.com's CEO Erik is thrilled for Chess.com to be able to offer this event:
