in this paper, we consider a class of column-weight two quasi-cyclic low-density paritycheck codes in which the girth can be large enough, as an arbitrary multiple of 8. then we devote a convolutional form to these codes, such that their generator matrix can be obtained by elementary row and column operations on the parity-check matrix. finally, we show that the free distance of the convolution...

background: related multidrug resistance (mdr) to efflux pumps is a significant problem in treating infections caused by pseudomonas aeruginosa (p. aeruginosa). plant compounds have been identified as pump inhibitors (epis). in the current study, the potential effect of berberine and palmatine as epis were investigated on efflux pump inhibition through focusing on different gene patterns in p. ae...

background: the pathogenesis of nontypeable haemophilus influenzae (nthi) begins with adhesion to the rhinopharyngeal mucosa. almost 38-80% of nthi clinical isolates produce proteins that belong to the high molecular weight (hmw) family of adhesins, which are believed to facilitate colonization. methods: in the present study, the prevalence of hmwa, which encodes the hmw adhesin, was determined...

background: the presence of rennin-angiotensin components in mammalian ovaries and their involvement in ovarian physiology have been established. in the present study, effects of angiotensin ii (ang ii) on sodium-potassium adenosine triphosphatase (na+/k+/atpase) expression and development of sheep embryos was evaluated. methods: the abattoir-derived cumulus oocyte complexes (coc) were randomly...

Multilength variable-weight optical orthogonal codes(MLVWOOCs) are recently proposed for supporting multirate and integrated multimedia services in code division multiple access (OCDMA) networks. Some work had been done on MLVWOOCs with weight set \begin{document}$ W = \{3, 4\} $\end{document}, id="M2">\b...
