Apport du LiDAR dans le géoréférencement d'images hyperspectrales en vue d'un couplage LiDAR/Hyperspectral

open access: yesRevue Française de Photogrammétrie et de Télédétection, 2015
Cette contribution présente deux méthodes de géoréférencement d'images hyperspectrales en se basant sur un jeu de données LiDAR acquises simultanément lors d'une campagne aéroportée en environnement côtier.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Damage Detection on a Beam with Multiple Cracks: A Simplified Method Based on Relative Frequency Shifts

open access: yesSensors, 2021
Identifying cracks in the incipient state is essential to prevent the failure of engineering structures. Detection methods relying on the analysis of the changes in modal parameters are widely used because of the advantages they present.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Iterative algorithm for accurate superposition of contours with non-uniform sampling step

open access: yesКомпьютерная оптика, 2023
In this article, we describe an iterative algorithm for accurate superposition of contours with non-uniform sampling step. The processing contours are characterized by the same shape, but the sampling step is non-uniform, with no matching between points ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Blind equalization of partial discharge channels [PDF]

open access: yesZbornik Radova: Elektrotehnički Institut "Nikola Tesla"
In the case of partial discharge signals, obtained during "online" monitoring or "off-line" tests of the generator, there is often interference between the direct and reflected signals or disturbances during propagation through the medium, i.e.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

The Closure Operator with the Equality Predicate Branching on the Set of Hyperfunctions on Two-Element Set

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2014
In this work we consider the closure operator with the equality predicate branching (E-operator) on the set of hyperfunctions on two-element set. With respect to this operator closed classes of hyperfunctions are generated.
