How can a plane wave represent a beam of particles? And what exactly is 'probability per unit time'? These questions bother every student of quantum mechanics when they encounter them in scattering theory. This chapter takes the mystery out of these issues, apart from offering a very concise ...
even though they do not all carry the same energy—in fact, they exhibit a range of energies. The specific motion of the particles near the transition
Nucleotide-binding leucine-rich repeat (NLR) receptors play crucial roles in plant immunity by sensing pathogen effectors1. In Arabidopsis, certain sensor NLRs function as NADases to catalyse the production of second messengers2,3, which can be recognize
He is a Russian particle physicist who, while working in an accelerator lab in 1978, managed to get his head directly in the path of a 76 GeV proton beam. Despite getting a huge dose of radiation, Bugorski not only survived the accident but managed to finish his Ph.D. and went on to...
Molecular beam mass spectrometry (MBMS) has been adapted at the gas dynamic stand LEMPUS-2to study the free molecular beam particle-scattering process on particles of the background gas. The verification of the used technique in noncondensing flows was carried out, and the results of measuring ...
A single-beam gradient-force optical trap for dielectric particles, which relies solely on the radiation pressure force of a TEM(00)-mode laser light, is demonstrated in air for what is believed to be the first time. It was observed that micrometer-sized glass spheres with a refractive index...
The chemical composition and energy contents of four different species of cladocerans, one species of a calenoid copepod, and mixed samples of four species of cyclopoid copepods were quantitatively determined. The relative chemical composition, expressed as a percentage of the total organic matter (exc...

The microstructures of an electron beam melted (EBM) nickel-based superalloy (Alloy 718) were comprehensively investigated in as-built and post-treated conditions, with particular focus individually on the contour (outer periphery) and hatch (core) regions of the build. The hatch region exhibited ...
