What Binarization Method Is the Best for Amplitude Inline Fresnel Holograms Synthesized for Divergent Beams Using the Direct Search with Random Trajectory Technique?

Journal of Imaging, 2023
Fast reconstruction of holographic and diffractive optical elements (DOE) can be implemented by binary digital micromirror devices (DMD). Since micromirrors of the DMD have two positions, the synthesized DOEs must be binary.

Runaway electrons and their interaction with tungsten wall: a comprehensive study of effects

Scientific Reports, 2023
Runaway electrons are a notable phenomenon occurring during the operation of a tokamak. Proper material selection for the tokamak's first wall structure and plasma facing components, particularly in large sizes tokamaks like ITER and DEMO, is crucial due

Numerical study of the wave-break in the vacuum-plasma interface during the interaction of an intense laser pulse

AIP Advances, 2017
In this paper, the wave break in the plasma-vacuum interface during the intense laser interaction is investigated. Since the nonlinear wave breaking is a non-adiabatic process, the fully kinetic 1D-3V Particle-In-Cell (PIC) simulation experiments are ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Comprehensive study of pollution removal from landfill leachate with emphasis on phenolic compounds and heavy metals using non-thermal plasma technology

Waste Management Bulletin
Landfill leachate poses a significant environmental threat. This study examined Non-thermal plasma (NTP) technology for treating landfill leachate after pretreatments to tackle this issue. EC and TDS decreased by over 96 %, COD by 98 %, turbidity by 97 %,
