Abstract: Two cylindrical reflex triodes (CRTs) in a parallel configuration have been simulated for the first time. Particle-in-cell (PIC) simulations show coupling between the inner and outer CRTs.

I mainly use this package for geometry construction in LAMMPS, with some examples provided in the repository; of course, it can also be used for other software. Particles of specified geometries are ...

Abstract: Particle-in-Cell (PIC) codes are widely used in plasma physics, but their computational requirements make efficient parallelization a major challenge, especially on heterogeneous systems ...

Despite its simplicity, the model is foundational. It is often the first non-trivial system for which students solve the Schrödinger equation exactly, and it beautifully illustrates core quantum ideas ...

A study published in the Proceedings of the National Academy of Sciences has uncovered new clues to why some therapeutic proteins are so difficult to manufacture. The work—led by Nathan Lewis, PhD, ...

This fundamental work substantially advances our understanding of how the glycocalyx of cells provide a non-specific barrier for the interaction of viruses with cell-surface receptors. Using both in ...

Tunable red to green emissions in upconversion nanoparticles allow precise identification of single particles, enabling accurate, long-term multicolor tracking in complex live cell environments.

Forget about turtles; for all practical purposes, it’s really particles all the way down. Consider the seemingly simple matter of their size, the very thing that makes them so alien. We’re typically ...

Background and objective: Particulate matters such as diesel exhaust particles induce oxidative stress in cells and thereby have a negative impact on health. The aim of this study was to test whether ...

Burmese pythons and other carnivorous snakes are well-known for swallowing their prey whole. But what comes out the other end doesn’t resemble what went in. There’s not a bone to be seen in their poop ...

Aim: This study examines the absolute quantification of particle uptake into cells. Methods: We developed a novel method to analyze stacks of confocal fluorescence images of single cells interacting ...
