Computer engineers design research platform for mixing processor cores to boost performance

Posted by in category: computing

Computers are renowned for flexibility, running everything from game consoles to stock exchanges. But at the level of computation, most computers rely on arrays of identical processors called cores. Now, a team at Princeton University has built a hardware platform that allows different kinds of computer cores to fit together, allowing designers to customize systems in new ways.

The goal is to create new systems that parcel out tasks among specialized cores, increasing efficiency and speed.

On top of multi– collaboration, even more gains are achievable when cores needn’t all rely on the same basic programming code that tells a core how to handle its processing jobs. Designers call this basic code an Instruction Set Architecture (ISA). Well-established ISAs include Intel x86, commonly found in laptops, ARM in smartphones, and POWER in IBM mainframes. Besides mixing together cores specialized for different ISAs, researchers are also interested in developing hybrid ISAs to underpin new processor designs, exploiting the potential of new, cutting-edge, open-source ISAs like RISC-V ISA.

The rate we acquire genetic mutations could help predict lifespan, fertility

Posted by in categories: genetics, life extension

Differences in the rate that genetic mutations accumulate in healthy young adults could help predict remaining lifespan in both sexes and the remaining years of fertility in women, according to University of Utah Health scientists. Their study, believed to be the first of its kind, found that young adults who acquired fewer mutations over time lived about five years longer than those who acquired them more rapidly.

The researchers say the discovery could eventually lead to the development of interventions to slow the .

“If the results from this small study are validated by other independent research, it would have tremendous implications,” says Lynn B. Jorde, Ph.D., chair of the Department of Human Genetics at U of U Health and a co-author of the study. “It would mean that we could possibly find ways to fix ourselves and live longer and better lives.”

Is teleportation possible? Yes, in the quantum world

Posted by in categories: computing, quantum physics, transportation

“Beam me up” is one of the most famous catchphrases from the Star Trek series. It is the command issued when a character wishes to teleport from a remote location back to the Starship Enterprise.

While human teleportation exists only in , teleportation is possible in the subatomic world of quantum mechanics—albeit not in the way typically depicted on TV. In the , teleportation involves the transportation of information, rather than the transportation of matter.

Last year scientists confirmed that information could be passed between photons on even when the photons were not physically linked.

Synthetic Plasma Liquid Based Electronic Circuits Realization-A Novel Concept

Posted by in categories: biotech/medical, engineering

Circa 2016


Biomedical research is contributing significant role in the field of biomedical engineering and applied science. It brings research and innovations to a different level. This study investigated artificial human blood –synthetic plasma liquid as conductive medium. Keeping in mind the conductivity of synthetic plasma, astable multivibrator as well as differential amplifier circuit were demonstrated. The circuits were given normal input voltages at regular temperature and ideal conditions. The result shows desired response which supports the novel concept. For both the circuits, phase shift of 180° achieved by analysing biological electronic circuits.

CityQ Car-eBike fully enclosed electric pedal car begins pre-orders

Posted by in categories: sustainability, transportation

:ooooo.


As e-bikes continue to explode in popularity and cause a nationwide shortage of the two-wheeled transports, waves of new riders are discovering the benefits of pedaling their way to work without breaking a sweat. And the ability to distance oneself from other commuters in crowded public transportation certainly sweetens the deal.

But many more are discovering a significant downside to bikes, which is that riders aren’t protected from the weather, be it heavy rain or the glaring sun. That’s a problem that CityQ is hoping to solve with its enclosed electric vehicle known as the CityQ Car-eBike.

China brings in hundreds of soldiers, heavy construction equipment to Galwan Valley

Posted by in category: futurism

Border talks carried out on Wednesday at the Major General-level to defuse the situation have also failed, indicating that the Chinese side is not looking to disengage. More talks are planned in the coming days but there has been no resolution on the ground situation that remains tense.

Sources said that despite earlier talks in which it was decided that the two sides would move back by a kilometre and create a temporary ‘no man’s land’ in the valley, the Chinese side has brought in additional troops and continues to remain deployed inside Indian territory near Patrol Point 14.

These PLA troops were among the 800 odd soldiers who laid ambush on an Indian patrol party, killing 20 soldiers including the commanding officer on Monday night.

Tesla Model 3 gets a solar roof thanks to Lightyear

Posted by in categories: energy, engineering, sustainability, transportation

A Tesla Model 3 has been modified with a solar roof as part of Lightyear’s solar car development program.

We have been reporting on Lightyear for a few years now.

The startup first caught our attention because it spun out of Solar Team Eindhoven, a group of engineering students from the Technical University of Eindhoven (Netherlands) who have been competing in the World Solar Challenge with their Stella and Stella Lux, energy positive solar cars — meaning that they can produce more energy than they consume.

Deep learning-based surrogate models outperform simulators and could hasten scientific discoveries

Posted by in categories: physics, robotics/AI

Surrogate models supported by neural networks can perform as well, and in some ways better, than computationally expensive simulators and could lead to new insights in complicated physics problems such as inertial confinement fusion (ICF), Lawrence Livermore National Laboratory (LLNL) scientists reported.

In a paper published by the Proceedings of the National Academy of Sciences (PNAS), LLNL researchers describe the development of a deep learning-driven Manifold & Cyclically Consistent (MaCC) surrogate model incorporating a multi-modal neural network capable of quickly and accurately emulating complex scientific processes, including the high-energy density physics involved in ICF.

The research team applied the model to ICF implosions performed at the National Ignition Facility (NIF), in which a computationally expensive numerical simulator is used to predict the energy yield of a target imploded by shock waves produced by the facility’s high-energy laser. Comparing the results of the neural network-backed surrogate to the existing simulator, the researchers found the surrogate could adequately replicate the simulator, and significantly outperformed the current state-of-the-art in surrogate models across a wide range of metrics.
