Tech Xplore / New diode chain could be used to develop high-power terahertz technologies
Electromagnetic waves with frequencies between microwave and infrared light, also known as terahertz radiation, are leveraged by many existing technologies, including various imaging tools and wireless communication systems. ...
Tech Xplore / RRAM-based analog computing system rapidly solves matrix equations with high precision
Analog computers are systems that perform computations by manipulating physical quantities such as electrical current, that map math variables, instead of representing information using abstraction with discrete binary values ...
Tech Xplore / AI efficiency advances with spintronic memory chip that combines storage and processing
To make accurate predictions and reliably complete desired tasks, most artificial intelligence (AI) systems need to rapidly analyze large amounts of data. This currently entails the transfer of data between processing and ...
Medical Xpress / A newly-discovered mechanism could contribute to the therapeutic effects of deep brain stimulation
Deep brain stimulation (DBS) is a surgical procedure that entails the delivery of high-frequency electrical impulses to specific regions of the brain, via surgically implanted electrodes. While it requires an invasive surgical ...
Medical Xpress / Oxytocin helps synchronize heartbeat and breathing, newly uncovered neural pathway suggests
When humans and other animals are in a calm state, they tend to breathe slower, and their heartbeat also slows down. Contrarily, when they are exercising or under psychological stress, both their breath and heartbeat tend ...
Tech Xplore / Literary character approach helps LLMs simulate more human-like personalities
After the advent of ChatGPT, the use of large language models (LLMs) has become increasingly widespread worldwide. LLMs are artificial intelligence (AI) systems trained on large sets of written texts, which can rapidly process ...
Tech Xplore / Molecular engineering strategy boosts efficiency of inverted perovskite solar cells
Solar cells, devices that can directly convert radiation emitted from the sun into electricity, have become increasingly widespread and are contributing to the reduction of greenhouse gas emissions worldwide. While existing ...
Tech Xplore / Skin-inspired organic biosensors can reliably track health-related signals in real-time
The rapid advancement of sensing and artificial intelligence (AI) systems has paved the way for the introduction of increasingly sophisticated wearable devices, such as fitness trackers and technologies that closely monitor ...
Tech Xplore / Organic solar cells reach 21% efficiency with two-step crystallization process
While most solar cells on the market today are based on silicon, energy engineers have recently been assessing the performance of alternative cells based on other photovoltaic (PV) materials. These alternative options include ...
Tech Xplore / Unified memristor-ferroelectric memory developed for energy-efficient training of AI systems
Over the past decades, electronics engineers have developed a wide range of memory devices that can safely and efficiently store increasing amounts of data. However, the different types of devices developed to date come with ...
Medical Xpress / Genetic underpinnings of substance use disorders in Europe, Africa and America identified, some previously unknown
Substance use disorders (SUDs) are mental health conditions characterized by the compulsive, uncontrolled and deleterious use of alcohol, tobacco, stimulants (e.g., cocaine or methamphetamines), opioids, cannabis and/or various ...
Tech Xplore / Three-layer microfluidic cooling device can remove heat from small electronics more efficiently
As electronic devices become increasingly powerful and compact, they can generate denser heat fluxes, or in other words, produce more heat in a smaller area. These heat fluxes raise the temperature of a device and can damage ...
Phys.org / How social norms evolved over time and differ across countries
When humans interact with each other and engage in everyday activities, they typically follow various undefined rules, also known as social norms. These rules include things like greeting acquaintances in specific ways upon ...
Tech Xplore / DeepMind introduces AI agent that learns to complete various tasks in a scalable world model
Over the past decade, deep learning has transformed how artificial intelligence (AI) agents perceive and act in digital environments, allowing them to master board games, control simulated robots and reliably tackle various ...
Medical Xpress / Astrocyte-derived vesicles could link stress to intestinal inflammation
Inflammatory bowel diseases (IBDs), such as Crohn's disease and ulcerative colitis, are chronic and autoimmune conditions characterized by the inflammation of the intestinal tract. This inflammation can cause nausea or vomiting, ...
