American engineers have created a powerful artificial “heart” for soft robots

US engineers have created an artificial “heart” to power soft robots that use fluid channels to deliver energy to moving parts. The pumps to move this fluid are often so bulky that they have to be placed outside the robot, but the new design is quite compact and suitable for “implantation” inside the robot.

American engineers have created a powerful artificial

Scientists from Cornell University and the US Army Research Laboratory have been able to create a powerful soft and small deformable pump for this purpose. It is driven by hydrodynamic and magnetic forces.

“Soft pumps work much like human hearts and arteries that circulate blood. Previously, we have already presented blood for robots. The combination of these two elements can make cars more realistic.”— said about the invention, Professor of Cornell University Robert Sheperd (Robert Sheperd).

The new pump is based on a soft silicone tube, on which a wire is wound as a magnetic coil. There is a magnet inside the tube. Depending on how the magnetic field is applied, the magnet can be moved back and forth like a piston to push through liquids such as water and low viscosity oils.

According to the authors, the performance of the pump and the pressure it creates are about 100 times greater than other soft pumps. Now scientists hope to create a soft robot built around this artificial “heart”.

Soft robots are created from soft materials similar to the tissues of living organisms. Unlike traditional rigid robots, soft robots provide increased flexibility and adaptability in performing tasks, as well as increased safety when working near people.

Xiaomi is in big trouble. The company’s net profit for the last quarter collapsed by 83%

Xiaomi is in big trouble The companys net profit for

Xiaomi has been hit hard by the decline in demand in the smartphone market. As the company’s latest financial report showed, its net income has plummeted an incredible 83% to $204 million. This turned out to be even lower than the company’s own forecasts.

Xiaomi is in big trouble.  The company's net profit for the last quarter collapsed by 83%

At the same time, revenue fell much less: by 20%, to $10.3 billion, and this is insignificant, but higher than forecasts.

In China, shipments of Xiaomi smartphones fell by 22% last quarter, while the overall market there fell by 14.7%. The fall of Xiaomi was the most significant among the market leaders. Xiaomi also came under fire in India, where the government decided to ban Chinese smartphone makers from selling devices under $150. True, this has not yet had time to affect the Xiaomi business.

The Galaxy S23 Ultra will indeed get a 200MP camera

Samsung will indeed equip the flagship smartphone Galaxy S23 Ultra with its 200-megapixel sensor for the main camera.

The Galaxy S23 Ultra will indeed get a 200MP camera.  Samsung allegedly confirmed this to its partners

The source claims that Samsung has already confirmed this information to its partners. Recall that we have heard such rumors before. At the same time, it is not yet clear which sensor the Korean giant will use, but rumors said that this would be a solution that has not yet been announced.

The Galaxy S23 Ultra will be the only flagship device with such a camera, but that’s to be expected, as the latest generation S2x Ultra models have always had a different camera than the younger versions. At the same time, it is possible that the Galaxy S23 / S23 + can get 108-megapixel sensors, previously reserved for Ultra versions.

Recall, the other day Motorola introduced the first smartphone with a 200-megapixel camera. The Moto X30 Pro features the first of its kind Samsung ISOCELL HP1 sensor.

Operating at only 66%, 96-core AMD processors wipe out all competitors. Epyc Genoa test results in Cinebench R23

Operating at only 66 96 core AMD processors wipe out all

The test results of two AMD Epyc server processors of the Genoa generation with 96 cores each have appeared on the Web. According to available data, this is either Epyc 9664 or Epyc 9654.

The CPU was tested in Cinebench R23, and the catch is that this software recognizes a maximum of 256 threads. Two 96-core processors have 384 threads thanks to SMT support. That is, the result obtained in the benchmark reflects only two thirds of the capabilities of the tested pair of CPUs.

Despite this, the processors scored over 110,000 points in multi-threaded mode. In a single thread, the result was 1302 points.

For comparison, one 64-core Threadripper 5995WX gains about the same amount (even a little more), but overclocked to 5.15 GHz using liquid nitrogen. The comparison with the direct competitor Xeon Platinum 8480+ is more interesting. A system with two of these 56-core processors scores only about 68,500 points. True, the source says that there were problems in the operation of these CPUs, so serial processors may show slightly better results. However, in any case, the gap is huge, because even two current-generation 64-core Epyc 7763 score 98,000 points. As a result, it is not yet clear whether the new Intel server processors will be able to somehow withstand the monsters of AMD. In addition, judging by the latest data, Sapphire Rapids-SP will eventually be delayed even more and will not be released until next year.
