Silicon nanoparticles based devices would allow to transmit, reflect, or scatter incident light in a specified direction, depending on its intensity. They could be integrated into microchips that would enable ultrafast all-optical signal processing in optical communication lines and the next generation optical computers.
Researchers have created strands of synthetic DNA that, when mixed together in a test tube in the right concentrations, form an analog circuit that can add, subtract and multiply as the molecules form and break bonds. While most DNA circuits are digital, their device performs calculations in an analog fashion by measuring the varying concentrations of specific DNA molecules directly, without requiring special circuitry to convert them to zeroes and ones first.
Scientists have demonstrated that chaos can be used to transmit information over a wireless physical channel offering wide-ranging advantages from enhanced communications security.
Patterns abound in nature, from zebra stripes and leopard spots to honeycombs and bands of clouds. Somehow, these patterns form and organize all by themselves. To better understand how, researchers have now created a new device that may allow scientists to study patterns in 3-D like never before.
Researchers have developed a novel approach to characterizing how atoms are arranged in materials, using Bayesian statistical methods to glean new insights into the structure of materials. The work should inform the development of new materials for use in a variety of applications.
The Piton chip's architecture is scalable; designs can be built which go from a dozen processing units (called cores) to several thousand.
Physicists probe the boundaries of light-matter interactions as they bridge traditional condensed matter physics and cavity-based quantum optics.
Scientists merged the domains of health policy with network science and dynamical systems to help understand the mechanisms of policy diffusion in the same way we understand the diffusion of one substance into another.
When they are confined to a small space, the behavior of electrons can only be explained by quantum physics. Much like electrons in an atom, they are forced into discrete quantum states. These states can be used for quantum information technologies.
Researchers have created a new theoretical framework which could help physicists and device engineers design better optoelectronics, leading to less heat generation and power consumption in electronic devices which source, detect, and control light.
Cybersecurity student researches spent the summer researching how to keep cars safe from cyberattacks during an intensive eight-week cybersecurity summer research program.
A scientific collaboration has discovered previously unknown regularities of arthropod limbs based on studies of the remipede Speleonectes tulumensis, a rare crustacean found in saline waters of caves.
Making an assistive robot partner expressive and communicative is likely to make it more satisfying to work with and lead to users trusting it more, even if it makes mistakes, a new study suggests.
The availability of accurate and reliable information on the location of impoverished zones is surprisingly lacking for much of the world. Applying machine learning to satellite images could identify impoverished regions in Africa, say researchers.
Waveguides are widely used for filtering, confining, guiding, coupling or splitting beams of visible light. However, creating waveguides that could do the same for X-rays has posed tremendous challenges in fabrication, so they are still only in an early stage of development.
Researchers, using the liquid crystal elastomer technology have demonstrated a bioinspired micro-robot capable of mimicking caterpillar gaits in natural scale. The 15-millimeter long soft robot harvests energy from green light and is controlled by spatially modulated laser beam. Apart from traveling on flat surfaces, it can also climb slopes, squeeze through narrow slits and transport loads.
A computational science doctoral student has successfully tied a new mathematical modeling process to the study of earthquakes.
A new study investigates and generalizes several well-known results from Extension theory of operators. In a new doctoral dissertation, a researcher has been able to improve a couple of classical theorems known in the area, namely Shmul'yan theorem on completion of nonnegative block operators and Krein famous theorem on description of selfadjoint contractive extensions of a Hermitian contraction.
Personalized wearable digital technology can help adults diagnosed with autism understand and manage their anxiety, say researchers.
Engineers have introduced a new way of communicating that allows power-constrained devices such as brain implants, contact lenses, credit cards and smaller wearable electronics to talk to everyday devices such as smartphones and watches.
