Kinetic Modeling of Vacuum Gas Oil Hydrotreatment using a Molecular Reconstruction Approach Modélisation cinétique de l’hydrotraitement de distillats sous vide utilisant une approche de reconstruction moléculaire

Oil & Gas Science and Technology, 2010
Vacuum Gas Oils (VGO) are heavy petroleum cuts (boiling points ranging from 350 to 550 ˚C) that can be transformed into valuable fuels (gasolines, diesels) by fluid catalytic cracking or hydrocracking.

Single‐Line Drawing Vectorization

Computer Graphics Forum, Volume 44, Issue 7, October 2025.
Abstract Vectorizing line drawings is a repetitive, yet necessary task that professional creatives must perform to obtain an easily editable and scalable digital representation of a raster sketch. State‐of‐the‐art automatic methods in this domain can create series of curves that closely fit the appearance of the drawing. However, they often neglect the

Optimizing VGOS observations using an SNR-based scheduling approach

Earth, Planets and Space
The geodetic and astrometric very long baseline interferometry (VLBI) community is in the process of upgrading its existing infrastructure with the VLBI Global Observing System (VGOS). The primary objective of VGOS is to substantially boost the number of

Ion Source Complementarity for Characterization of Complex Organic Mixtures Using Fourier Transform Mass Spectrometry: A Review

Mass Spectrometry Reviews, Volume 44, Issue 5, Page 808-829, September/October 2025.
ABSTRACT Complex organic mixtures are found in many areas of research, such as energy, environment, health, planetology, and cultural heritage, to name but a few. However, due to their complex chemical composition, which holds an extensive potential of information at the molecular level, their molecular characterization is challenging.

VGOS CRF: Celestial Reference Frame from VGOS until Dec 2024

We present a celestial reference frame (CRF) from Very Long Baseline Interferometry (VLBI) Global Observing System (VGOS) including data until December 2024. The VGOS CRF is built with 1.8 million group delays observed in 193 multi-baseline 24-hour sessions (178 VGOS-OPS, 15 VGOS-R&D) with a fixed frequency distribution.

The Effect of Hydroalcoholic Extract of Salvia miltiorrhiza on Hormonal and Cellular Parameters of Spermatogenesis in Male Rats After the Consumption of Ibuprofen

Food Science &Nutrition, Volume 13, Issue 8, August 2025.
SM extract could be able to counter inflammation owing to the extra consumption of popular drugs such as ibuprofen. ABSTRACT Salvia miltiorrhiza (SM), a medicinal herb known for its antioxidant and anti‐inflammatory properties, has been traditionally used to treat various physiological disorders.

The impacts of source structure on geodetic parameters demonstrated by the radio source 3C371

, 2017
Closure quantities measured by very long baseline interferometry (VLBI) observations are independent of instrumental and propagation instabilities and antenna gain factors, but are sensitive to source structure.

Controlling Rayleigh-Backscattering-Induced Distortion in Radio over Fiber Systems for Radioastronomic Applications [PDF]

, 2020
Radio over Fiber (RoF) Systems exploiting a direct modulation of the laser source are presently utilized within important Radioastronomic scenarios. Due to the particular operating conditions of some of these realizations, the phenomena which typically ...

Voronoi Cell Interface‐Based Parameter Sensitivity Analysis for Labeled Samples

Computer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract Varying the input parameters of simulations or experiments often leads to different classes of results. Parameter sensitivity analysis in this context includes estimating the sensitivity to the individual parameters, that is, to understand which parameters contribute most to changes in output classifications and for which parameter ranges ...
