South Korean researchers have developed a new type of electrode structure for all-solid-state secondary batteries. If this technology is adopted, the energy density of the batteries could increase significantly when compared to existing technologies, contributing tremendously to the development of high-performance secondary batteries.
Research shows nitrogen efficiency and productivity not a tradeoff.
Designing a vehicle that can drive away the heat that is generated around it when traveling at hypersonic speeds requires an understanding of the thermal properties of the materials used to construct it. A recent two-part study at the University of Illinois Urbana-Champaign developed a method to create 3D models of the fibers within composite materials then used that information to predict the thermal conductivity of the material.
Imagine a silent helicopter stealthily moving troops and supplies around a future battlefield. U.S. Army researchers look to helicopter noise reduction technology as a top priority in aircraft design. At the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory, researchers collaborated with Uber and the University of Texas at Austin to investigate the acoustic properties of electric vertical takeoff and landing aircraft, which use distributed electric propulsion to power flight.
A University of Toronto Engineering study is underscoring the importance of drivers keeping their eyes on the road -- even when they are in an automated vehicle (AV). The findings, published recently in the journal Accident Analysis & Prevention, revealed that drivers can become over-reliant on AV technology. This was especially true with a type of in-vehicle display the team coined as takeover request and automation capability (TORAC).
Today's tomatoes are larger and easier to farm than their wild ancestor, but they also are less resistant to disease and environmental stresses like drought and salty soil. Researchers from Boyce Thompson Institute created a high-quality genome for the ancestor, discovering structural variants that are involved in fruit flavor, size and ripening, stress tolerance and disease resistance. Plant breeders could use the resource to develop tomatoes that taste better, are more nutritious and more resilient.
Freehand gesture-based interfaces in interactive systems are becoming more common, but what if your preferred way to gesture a command - say, changing the TV to channel 10 - significantly differed from that of a user from another culture? Would the system recognize your command? Researchers from the Penn State College of Information Sciences and Technology and their collaborators explored this question and found that some gesture choices are significantly influenced by the cultural backgrounds of participants.
Deep learning neural networks can be massive, demanding major computing power. In a test of the "lottery ticket hypothesis," MIT researchers have found leaner, more efficient subnetworks hidden within BERT models. The discovery could make natural language processing more accessible.
In a new study published in the Journal of Biomedical Optics, researchers from Johns Hopkins University, Mason T. Chen and Nicholas J. Durr, have proposed an end-to-end technique for accurate calculation of tissue oxygenation from single snapshots, called OxyGAN.
HSE University scientists have for the first time in the world investigated the impact of delayed reinforcement signals in neurofeedback (NFB) training. They have experimentally proven that reducing the delay in feedback (decreasing feedback latency) can significantly increase the efficacy of training. This opens up new potential for the use of NFB for cognitive enhancement, self-regulation, and the treatment of a broad range of neurological disorders from anxiety and depression to epilepsy.
