Broadcasting is an indispensable operation to provide control or routing functionalities for multi-hop mobile ad-hoc networks (MANETs). In MANET, since a packet relayed by any node can reach all its neighbor nodes, broadcasting by traditional flooding is inefficient and results in severe redundancies, contentions, and collisions.

Journal of Polymer Science Part A: Polymer Chemistry, 2019
ABSTRACTWe report the synthesis of high‐molecular‐weight linear polyisobutylenes (PIBs) and PIB networks from low‐molecular‐weight PIB by thiol‐ene click chemistry. Thus, liquid allyl‐telechelic PIB was reacted with small di‐ and tri‐thiols, and the thiolated intermediates chain‐extended by UV‐ or thermally induced free radical initiation to linear and

Overproduction of PIB-Type ATPases
2016Understanding of the functions and mechanisms of fundamental processes in the cell requires structural information. Structural studies of membrane proteins typically necessitate large amounts of purified and preferably homogenous target protein. Here, we describe a rapid overproduction and purification strategy of a bacterial PIB-type ATPase for ...

Femmes et richesse : au-delà du PIB
Travail, genre et sociétés, 2011Résumé La mesure actuellement la plus utilisée pour recenser la richesse d’un pays est le Produit intérieur brut, qui représente la valeur monétaire des biens et services fabriqués une année donnée. Cet indicateur a été inventé au sortir de la Seconde Guerre mondiale.

L'hégémonie anachronique du PIB
Idées économiques et sociales, 2013On ne saurait trop rappeler aux décideurs publics que la nuance subtile entre croissance du produit intérieur brut (PIB) et progression du bien-être ne date pas d’hier. L’inventeur du PIB, Simon Kuznets, prévenait déjà en 1934 que « la mesure du revenu national peut difficilement servir à évaluer le bien-être d’une nation ».

PIB potentiel et écart de PIB : quelques évaluations pour la France. [PDF]
, 2002 This Study and Research Paper is devoted to different estimates of the French economy's potential output and output gap. Several methods, which are presented in detail, are put forward to measure these indicators. The first two sections of the paper profile statistical univariate approaches: smoothing using the Hodrick-Prescott filter; and estimation ...

Brain amyloid imaging is becoming an essential tool for the pre-mortem evaluation of Alzheimer's disease (AD). This study explores the pattern of^{11}C-PiB retention in a subject with Worster-Drought syndrome (WDS). A 55 year-old male carrier of the WDS gene mutation with mild signs of ataxia and subtle cognitive impairment underwent MRI and^{11}C-PiB ...

Le PIB : une mesure contestée ?
2008Élaboré aux États-Unis pendant la Grande Dépression, le produit intérieur brut (PIB) est rapidement devenu un indicateur de référence, à l’aune duquel sont évaluées et comparées les performances économiques des pays, voire le bien-être de leurs citoyens.
