Quantitative Model of Internal Analyzer Scattering in a Hemispherical Electron Analyzer and Its Application to Improve the Accuracy of the Transmission Function

Surface and Interface Analysis, EarlyView.
ABSTRACT Internal scattering within hemispherical electron analyzers (HEA) is common when operating at low pass energies, where the instrument resolution of X‐ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy experiments are at their best.

Neural Local Inter‐reflection Modeling for Garment Fold Rendering

Computer Graphics Forum, EarlyView.
Abstract Realistic garment rendering requires simulating complex multi‐bounce light paths within intricate fold geometries. In these regions, conventional path tracing is computationally expensive as light becomes trapped, necessitating high bounce counts for convergence.

On the (non-)existence of polynomial kernels for Pl-free edge modification problems

, 2010
Given a graph G = (V,E) and an integer k, an edge modification problem for a graph property P consists in deciding whether there exists a set of edges F of size at most k such that the graph H = (V,E \vartriangle F) satisfies the property P.

Dynamical simulation of on‐axis transmission Kikuchi and spot diffraction patterns, based on accurate diffraction geometry calibration

Journal of Microscopy, EarlyView.
Abstract Transmission Kikuchi diffraction in the scanning electron microscope has gained popularity as a materials characterisation technique for its high throughput and nanometre‐level spatial resolution. While conventional diffraction pattern analysis routines focus on Kikuchi bands on the diffraction patterns, the full physical picture of electron ...

Radiative Bulk Viscosity

, 2001
Viscous resistance to changes in the volume of a gas arises when different degrees of freedom have different relaxation times. Collisions tend to oppose the resulting departures from equilibrium and, in so doing, generate entropy.
