Potentiation of insulin secretion from pancreatic β-cells by acetylcholine requires ongoing cyclic electrical activity initiated by other depolarizing secretagogues. Patch-clamp recordings in glucose-free solutions were made from the clonal β-cell line HIT-T15 to determine whether the muscarinic agonist bethanechol (BCh) modulated voltage-dependent Ca2+ channels independent of effects on membra...

Apricitabine (ATC) is a novel deoxycytidine analog reverse transcriptase inhibitor in development for the treatment of human immunodeficiency virus infection. Studies were performed to characterize the excretion of ATC and its metabolite, BCH-335 (-1-(2-hydroxymethyl-[1,3]oxathiolan-4-yl)-1H-pyrimidine-2,4-dione), in the isolated perfused rat kidney (IPK). A second objective was to investigate ...

Error Correcting Codes are required to have a reliable communication through a medium that has an unacceptable bit error rate and low signal to noise ratio. In IEEE 802.15.6 2.4GHz Wireless Body Area Network (WBAN), data gets corrupted during the transmission and reception due to noises and interferences. Ultra low power operation is crucial to prolong the life of implantable devices. Hence sim...

The decoding beyond the Bose-Chaudhuri-Hocquenghem (BCH) bound is always an interesting research topic in block error correction codes. However, searching a complete decoding algorithm is not easy since all the error patterns that belong to the coset leaders of the standard array need to be correctable [1]. Both the well-known standard algebraic method and the step-by-step method can be used to...

Amino acids have an important role in the pre and post implantation of placenta and embryo development. l-type amino-acid transporter 1 (lat1) is responsible for the transportation of large neutral amino acids and is mainly expressed in human fetal liver, placenta, brain, etc. This study is the first to investigate the expression of lat1 in the early pregnancy of mouse uteri and its role in the...

This paper presents a two-iteration concatenated Bose-Chaudhuri-Hocquenghem (BCH) code and its highspeed low-complexity two-parallel decoder architecture for 100 Gb/s optical communications. The proposed architecture features a very high data processing rate as well as excellent error correction capability. A low-complexity syndrome computation architecture and a high-speed dual-processing pipe...

The Bose, Chaudhuri and Hocquenghem (BCH) codes form a large class of powerful random-error correcting cyclic codes. However, the implementation of its decoder requires high-complexity computation resources with a huge number of sequential circuits. This paper presents a low-complexity register transfer level (RTL) circuit design of a BCH decoder. In accordance with the table relationship betwe...

Still Image/Video is one of the most important and also one of the most challenging types of traffic on communication networks. One of the challenges arises because communication networks can insert errors into still Image/Video, and also compressed image or compressed Video is fragile in the presence of errors; that are a single error can propagate over a large portion of the Image/Video. This...

Il faut distinguer les codes correcteurs d’erreurs de la cryptographie. Les codes correcteurs d’erreur servent à protéger l’information d’erreurs de transmission ou de stockage. On peut trouver dans ce texte, avec des références bibliographiques précises, des idées d’exposés ou d’applications pour plusieurs leçons portant sur l’algèbre linéaire ou les polynômes. (Les titres des leçons sont ceux...
