Researchers extend the mathematical approach called automatic differentiation from machine learning to the fitting of model parameters that describe the behavior of field-effect transistors. This allowed the parameters to be extracted up to 3.5 times faster compared with previous methods, which may lead to more sustainable microelectronics. Wide bandgap devices, such as silicon carbide (SiC)…

One potential cost-effective way to sustain ageing concrete subjected to harsh environmental conditions is to externally coat the material with fiber reinforced polymer composites. But few studies have looked at the durability of such strengthening. Now, researchers from Korea and the USA conduct a 13-year long experiment to find out. In the FRP-strengthening of concrete,…

Using machine learning and simulations of giant impacts, researchers found that the planets residing in the inner solar system were likely born from repeated hit-and-run collisions, challenging conventional models of planet formation. The findings challenge the conventional view, in which collisions between smaller building blocks cause them to stick together and, over time, repeated collisions…

Researchers have demonstrated a new way to control the quantum state through the loss of particles — a process that is usually avoided in the quantum device, offering a new way towards the realization of unprecedented quantum states. Manipulating a quantum system requires a subtle control of quantum state with zero imperfect operations, otherwise the…

Oil and water do not mix, but what happens where oil and water meet? Or where air meets liquid? Unique reactions occur at these interfaces, which a team of researchers based in Japan used to develop the first successful construction of uniform, electrically conductive nanosheets needed for next-generation sensors and energy production technologies. The research…

Scientists have simulated the growth of diamond films to reveal geometrical properties and insights on how to grow these films more efficiently in the lab. In today’s societies, the word «diamond» brings to mind a series of images. It entails stories of strength, wealth, and status. But strip away these associations, and the scientific uses…

Researchers found that last-mile delivery networks will become more decentralized and the delivery speed of the drones will increase as the technology matures. In a new study, recently published online in Production and Operations Management, three faculty members from the Naveen Jindal School of Management explored how drone delivery could change retail logistics networks. The…

Researchers have developed a new approach to speed up hydrogen atoms moving through a crystal lattice structure at lower temperatures. «Improving hydrogen transport in solids could lead to more sustainable sources of energy,» says Hiroshi Kageyama of iCeMS who led the study. Negatively charged hydrogen ‘anions’ can move very quickly through a solid ‘hydride’ material,…

Researchers have discovered an unusual pulsar — one of deep space’s magnetized spinning neutron-star ‘lighthouses’ that emits highly focused radio waves from its magnetic poles. It is unusual because the masses of its two neutron stars are quite different — with one far larger than the other. The breakthrough provides clues about unsolved mysteries in…

A small chip inserted under the skin can monitor patients after common forms of stroke to predict those at high risk of a recurrent stroke. The chip may help physicians identify patients who could benefit from stroke prevention therapies. Each year, approximately 800,000 strokes occur in the United States, and as many as one-fourth occur…
