High throughput and fair resource sharing are two of the most important objectives in designing a medium access control (MAC) protocol. Currently, most MAC protocols including IEEE 802.11 DCF adopt a random access based approach in a distributed manner in order to coordinate the wireless channel accesses among competing stations. In this paper, we first identify that a random access–based MAC p...

Les crispations autour des études postcoloniales et plus largement enjeux liés à la « race » en éducation France rendent difficiles réflexions précises approfondies sur les pratiques éducatives qui se veulent décoloniales et/ou antiracistes ; de là l’importance d’étudier d’autres contextes. L’arti...

The requirement of high quality service (QoS) in multi-priority industrial and domestic sensor networks poses new challenges to the increasing adoption Internet Things (IoT). In Multi-event Wireless Sensor Networks (MWSNs), nodes generate different types data packets i.e., urgent (high priority) or normal (low priority), with traffic proportions. High priority require an assurance faster transm...

AbstmctThe objective of this paper is t o propose a methodology and framework for integrating different MAC protocols into a single shared medium network t o efficiently accommodate various types of multimedia t r d c streams with different characteristics and QoS demands. In particular, we propose an integrated M A C protocol which is termed Multimedia Medium Access Control (Multimedia-MAC) pr...

BACKGROUND AND AIMS Bispectral index (BIS) values may be anaesthetic agent-specific, depending on their ability to suppress the electroencephalogram (EEG) signals. We carried out a prospective, randomised clinical trial to study the effect of nitrous oxide (N2O) on the BIS values at an equi-minimum alveolar concentration (MAC) of sevoflurane and desflurane. METHODS Sixty adult patients underg...

Random bred Syrian hamsters given s.c. injections of SV40 small t deletion mutants dl883, dl884, and dl890 rapidly develop reticulum cell sarcomas in the abdominal cavity in addition to slowly developing s.c. fibrosarcomas at the site of virus inoculation. Injection of wild type SV40 s.c. induces only fibrosarcomas at the site of inoculation. In an attempt to understand why mutations in the SV4...
