The simultaneous generation of an electron beam with high energy and high current density with a high-fill factor is challenging for a backward wave oscillator (BWO) and other linear-beam devices. To ...

Scientists have discovered a revolutionary new method for creating quantum states by twisting materials at the M-point, revealing exotic phenomena previously out of reach. This new direction ...

For decades, ferromagnetic materials have driven technologies like magnetic hard drives, magnetic random access memories and ...

Purpose To investigate the characteristics of human orbital fibroblasts (OFs) cultivated from intraconal, nasal and central adipose tissues. Methods Intraconal adipose tissues were obtained during ...

We present an orbital-resolved extension of the Hubbard U correction to density-functional theory (DFT). Compared to the conventional shell-averaged approach, the prediction of energetic, electronic ...

Chinese satellites are experimenting with increasingly sophisticated maneuvers in space, making U.S. officials uneasy that these orbital behaviors could give Beijing an advantage in a future conflict.

It is shown that compressive mechanical stress considerably enhances the impact ionization rate and the generation of secondary electron-hole pairs. These can be trapped in the gate oxide and cause a ...

Automating the analysis portion of materials characterization by electron microscopy (EM) has the potential to accelerate the process of scientific discovery. To this end, we present a Bayesian ...
