In a multi-group multicast sparse code multiple access (SCMA) system, one base station multicasts common messages to groups via different books. To accommodate more user terminals (UTs), traditional systems have transmitters, each of which works in one-to-many mode. this way, UT is subject inter-transmitter interference. Considering the high degrees freedom for transmitting and receiving, it di...

There are two main shortcomings in the existing models for generating checking sequences based on distinguishing sequences. First, these models require a priori selection of state recognition sequences (called αsequences) which may not be the best selection for yielding substantial reduction in the length of checking sequences. Second, they do not take advantage of overlapping to further reduce...

The genetic basis for bacterial mercury methylation has been described recently. For insights into the physiology of mercury-methylating bacteria, we present genome sequences for Desulfococcus multivorans strain DSM 2059, Desulfovibrio alkalitolerans strain DSM 16529, and Desulfovibrio species strain X2.

for any lacunary sequence $theta = (k_{r})$, we define the concepts of $s_{theta}-$limit point and $s_{theta}-$cluster point of a sequence of fuzzy numbers $x = (x_{k})$. we introduce the new sets  $lambda^{f}_{s_{theta}}(x)$, $gamma^{f}_{s_{theta}}(x)$ and prove some inclusion relaions between these and the sets $lambda^{f}_{s}(x)$, $gamma^{f}_{s}(x)$ introduced in ~cite{ayt:slpsfn} by aytar [...

Sixty-two partial formyltetrahydrofolate synthetase (FTHFS) structural gene sequences were recovered from roots of salt marsh plants, including Spartina alterniflora, Salicornia virginica, and Juncus roemerianus. Only S. alterniflora roots yielded sequences grouping with FTHFS sequences from known acetogens. Most other FTHFS or FTHFS-like sequences grouped with those from sulfate-reducing bacte...

boophilus genus ticks are responsible for transferring some pathogens and reducing production factors in cattle. tropomysin (tpm) protein has actin regulator activity and playing important role in immune and allergic reactions. the main goal is to determine different aspects of phylogenetic, similarity, homology, structure and allergenicity of tpm protein. in prior study, we identified tpm by u...

background:   human fascioliasis is an important health problem in the province of gilan, at the caspian sea, iran. there is the overlapping of both fasciolid species, fasciola hepatica and f. gigantica . recent studies on both domestic animal and lym­naeid infection furnished evidence suggesting that f. gigantica and radix gedrosiana may be the main fasciolid and lym­naeid involved in the dise...
