Abstract: The calculation of the visible time window (VTW) of synthetic aperture radar (SAR) satellite to regional target plays an important role in SAR satellite mission planning. At present, the VTW ...

A new draft standard, ISO/DIS 18841, is under development by members of the International Organization for Standardization (ISO) to replace ISO 18841:2018, the existing general standard for ...

Whether you’re solving geometry problems, handling scientific computations, or processing data arrays, calculating square roots in Python is a fundamental task. Python offers multiple approaches for ...

ABSTRACT: In this article, we propose developing a reliable and sensitive method for determining tryptamine (TRYP) levels in canned fish samples using spectrofluorimetric analysis. The analytical ...

Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) is a promising tool for the spatial quantitation of endogenous and exogenous compounds directly in biological tissue ...

This script automates a computational chemistry workflow starting from SMILES: Converts SMILES strings to 3D XYZ coordinates using RDKit. (Parallel) Runs a chain of XTB calculations (opt, scc, vipea, ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

Abstract: The unconditionally stable (US) Chebyshev (CS) finite-difference time-domain (FDTD) method is extended for solving the problems of long-time simulation or harmonic resonance using a ...

Assets like equipment, vehicles and furniture lose value as they age. Parts wear out and pieces break, eventually requiring repair or replacement. Depreciation helps companies account for the ...

When scaling an established analytical method across columns packed with different particle sizes and different column configurations (internal diameters and lengths), the amount of time that is ...
