Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

A Bayesian Compressive Data Gathering Scheme in Wireless Sensor Networks With One Mobile Sink

open access: yesIEEE Access, 2018
This paper studies the compressive data gathering problem in terms of Bayesian theory for wireless sensor networks (WSNs) with a mobile sink. In such WSNs, designing an optimal tour path for sink is a challenge task, because topology is time-varying and ...

Un gazetier des places portuaires françaises du xviiie siècle

open access: yesHumanités Numériques, 2021
This article presents the methodology and choices we made to produce and publish on the semantic Web a gazetteer of French ports in activity between 1749 and 1815 and of foreign ports they were connected to, including their belonging to historical ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

A new chain-based data gathering protocol for wireless sensor transportation monitoring network

open access: yes, 2006
Data gathering is one of the most important processes in wireless sensor networks (WSN). The sensor nodes gather information and send it to a base station, which consumes significant amounts of power. Due to the limited battery life, energy efficiency is

Les défis d’une approche multisource et diachronique de l’occupation du sol : l’exemple de la vallée de la Garonne

open access: yesHumanités Numériques, 2021
The history of land use dynamics can only be written by apprehending a long period of time that transcends academic divisions. It is a necessary step to finely perceive the stages of construction of rural spaces by ancient societies. It requires recourse

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

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.

UAV Path Optimization for Precision Agriculture Wireless Sensor Networks

open access: yesSensors, 2020
The use of monitoring sensors is increasingly present in the context of precision agriculture. Usually, these sensor nodes (SNs) alternate their states between periods of activation and hibernation to reduce battery usage.
