Laser wakefield and direct acceleration in the plasma bubble regime [PDF]
, 2018 Laser wakefield acceleration (LWFA) and direct laser acceleration (DLA) are two different kinds of laser plasma electron acceleration mechanisms. LWFA relies on the laser-driven plasma wave to accelerate electrons.

Towards realistic simulations of QED cascades: non-ideal laser and electron seeding effects
, 2018 A number of analytical and numerical studies has been performed to investigate the onset and the development of QED cascades in the collision of two counterpropagating laser pulses as a function of the laser intensity.

Apparatus to control and visualize the impact of a high-energy laser pulse on a liquid target [PDF]
, 2017 We present an experimental apparatus to control and visualize the response of a liquid target to a laser-induced vaporization. We use a millimeter-sized drop as target and present two liquid-dye solutions that allow a variation of the absorption ...

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Diffusion von Spaltprodukten bei überlagerter chemischer Reaktion: Mathematische Grundlagen [PDF]
, 1966 Die bisher veröffentlichten Untersuchungen über den Massentransport von Spaltprodukten in Graphit lassen darauf schließen, daß keine reine Diffusion vorliegt, sondern daß diese durch eine oder mehrere Reaktionen überlagert ist.

Mitochondrial fatty acid oxidation is stimulated by red light irradiation
FEBS Letters, EarlyView.Light at different wavelengths has distinct effects on keratinocyte viability and metabolism. UVA light abrogates metabolic fluxes. Blue and green light have no effect on metabolic fluxes, while red light enhanced oxidative phosphorylation by promoting fatty acid oxidation. Keratinocytes are the primary constituents of sunlight‐exposed epidermis.

Non-Uniform Offsetting and its Applications in Laser Path Planning of Sterolithography Machine [PDF]
, 2007 Laser path planning is an important step in solid freeform fabrication processes such as Stereolithography (SLA). An important consideration in the laser path planning is to compensate the shape of laser beam. Currently the compensation is divided into

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots
FEBS Letters, EarlyView.This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Implementation of Ag/ SiO2 nanofilms for metamaterial engineering
Results in Physics, 2022 Low dimensions of the nanostructured thin films are essential in applications of miniaturized optical systems. Noble metal thin films of different thicknesses (4–10 nm) were obtained by radio frequency magnetron sputtering (rfMS) with controlled ...
