Engineering researchers have developed a gunshot detection algorithm and classification model that can discern similar sounds such as gunfire or a plastic bag popping. Discerning between a dangerous audio event like a gun firing and a non-life-threatening event, such as a plastic bag bursting, can mean the difference between life and death. Additionally, it also…

In another verification of the validity of Einstein’s theory of general relativity scientists have used two finely tuned optical lattice clocks to make new ultra-precise measurements of the time dilation effect predicted by Einstein’s theory of general relativity. Einstein theorized that the warping of time-space by gravity was caused by massive objects. In line with…

Researchers have invented a way to integrate ‘breadboards’ — flat platforms widely used for electronics prototyping — directly onto physical products. The aim is to provide a faster, easier way to test circuit functions and user interactions with products such as smart devices and flexible electronics. Breadboards are rectangular boards with arrays of pinholes drilled…

Multi-domain operations, the Army’s future operating concept, requires autonomous agents with learning components to operate alongside the warfighter. New research reduces the unpredictability of current training reinforcement learning policies so that they are more practically applicable to physical systems, especially ground robots. These learning components will permit autonomous agents to reason and adapt to changing…

Using data collected in a NASA wind tunnel, researchers replicated the hypersonic flow conditions of a compression ramp flow using Direct Numerical Simulation. «Data from experiments are somewhat limited — for example taken from pressure probes at a few locations on a test object. When we run a numerical simulation, we acquire information — such…

Adding a layer of nanoparticles to LED designs could help them produce more light for the same energy, and also increase their lifetime. This is according to a team from Imperial College London and the Indian Institute of Technology (IIT) Guwahati who have found a new way to boost the amount of light LEDs produce.…

Scientists have discovered one of the largest anomalous Hall effects (15,506 siemens per centimeter at 2 Kelvin) ever observed in a new compound. This material has a never-before-seen combination of properties: Dirac physics, frustrated magnetism, 2D exfoliatability, and chemical stability. Aside from future fundamental research studying the interplay of these ingredients, the unique combination has…

Scientists have developed a new technique that could revolutionize medical imaging procedures using light. A team of physicists, led by Dr David Phillips from the University of Exeter, have pioneered a new way in which to control light that has been scrambled by passage through a single hair-thin strand of optical fibre. These ultra-thin fibres…

A lab, whose work is concentrated on neuromorphic computing or brain-inspired computing, has new research that introduces hardware improvements by harnessing a quality known as ‘randomness’ or ‘stochasticity’. Their research contradicts the perception of randomness as a quality that will negatively impact computation results and demonstrates the utilization of finely controlled stochastic features in semiconductor…

With the insertion of a little math, researchers have shown that neuromorphic computers, which synthetically replicate the brain’s logic, can solve more complex problems than those posed by artificial intelligence and may even earn a place in high-performance computing. Neuromorphic simulations employing random walks can track X-rays passing through bone and soft tissue, disease passing…
