Multi-domain operations, the Army's future operating concept, requires autonomous agents with learning components to operate alongside the warfighter. New Army 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 … [Read more...] about More effective training model for robots

Today, nanotechnology allows one to observe single proteins at work. Under atomic force microscopy (AFM), e.g., their surface can be rapidly scanned, and functional motions monitored, which is of great importance for applications in all fields of Life science. The analysis and interpretation of experimental results remains however challenging because the resolution of obtained … [Read more...] about BioAFMviewer software for simulated atomic force microscopy of biomolecules

Quantum computer: One of the obstacles for progress in the quest for a working quantum computer has been that the working devices that go into a quantum computer and perform the actual calculations, the qubits, have hitherto been made by universities and in small numbers. But in recent years, a pan-European collaboration, in partnership with French microelectronics leader … [Read more...] about Important milestone in the creation of a quantum computer

Most people underestimate exponential growth, including when it comes to the spread of the coronavirus. The ability to grasp the magnitude of exponential growth depends on the way in which it is communicated. Using the right framing helps to understand the benefit of mitigation measures. The coronavirus outbreak offered the public a crash course in statistics, with terms like … [Read more...] about Grasping exponential growth

This summer, when bars and restaurants and stores began to reopen across the United States, people headed out despite the continuing threat of COVID-19. As a result, many areas, including the St. Louis region, saw increases in cases in July. Using mathematical modeling, new interdisciplinary research from the lab of Arye Nehorai, the Eugene & Martha Lohman Professor of … [Read more...] about Mathematical modeling can help balance economy, health during pandemic: Nearly 300,000 deaths could be averted, depending on how severe isolation measures become

Anyone entering the world of quantum physics must prepare themself for quite a few things unknown in the everyday world: Noble gases form compounds, atoms behave like particles and waves at the same time and events that in the macroscopic world exclude each other occur simultaneously. In the world of quantum physics, Reinhard Dörner and his team are working with molecules which … [Read more...] about Quantum wave in helium dimer filmed for the first time

Transparent electronics -- such as head-up displays that allow pilots to read flight data while keeping their eyes ahead of them -- improve safety and allow users to access data while in transit. For healthcare applications, the electronics need to not only be cheap and straightforward to fabricate, but also sufficiently flexible to conform to skin. Silver nanowire networks … [Read more...] about Toward imperceptible electronics that you cannot see or feel

Atomistic simulations are a powerful tool to study the movement and interactions of atoms and molecules. In many biological processes, large-scale effects, for example, assembly of large viruses to nanoparticles are important. The assembly processes of these large viruses are of fundamental importance to the design of many devices and viral protein-targeted therapeutics. … [Read more...] about Scientists simulate a large-scale virus, M13

Adapting a traditional endless runner video game and using a raccoon as the protagonist, researchers from the Universidad Carlos III de Madrid (UC3M) and the Complutense University of Madrid (UCM, in its Spanish acronym), among other institutions, have developed a platform that allows the identification and evaluation of the degree of attention deficit hyperactivity disorder … [Read more...] about Video game can identify attention deficit symptoms

Advances in neuroscience and engineering have generated great hope for Luke Skywalker-like prosthetics: robotic devices that are almost indistinguishable from a human limb. Key to solving this challenge is designing devices that not only can be operated with a user's own neural activity, but can also accurately and precisely receive and relay sensory information to the user. A … [Read more...] about Even after long-term exposure, bionic touch does not remap the brain
