in this paper, an algorithm , based on genetics and auxiliary nodes, to reduce energy consumption in wireless sensor networks has been presented. in this research, by considering some parameters as energy and distance, a target function has been created, which is more optimum comparing to other methods. in this research cluster head is selected by genetic algorithm. in rawsn algorithm a new tec...

agent-based negotiation is one of the interesting approaches in the field of automated negotiation in the e-commerce world. establishment an automated negotiation needs to develop a mechanism for it and it is obvious that users would accept a mechanism that is reliable alternative for negotiating individual. therefore, the need to developing efficient and reliable agent-based negotiation mechan...

Four round Feistel permutation (like DES) is super-pseudorandom if each round function is random or a secret universal hash function. A similar result is known for five round MISTY type permutation. It seems that each round function must be at least either random or secret in both cases. In this paper, however, we show that the second round permutation g in five round MISTY type permutation nee...

spermatids are the earliest male germ cells with one set of haploid chromosomes. after experiments, mainly in rodents, the spermatid injection was introduced in human assisted reproduction to the treatment of men with non-obstructive azoospermia. spermatid injection is a technique with particular difficulties that may negatively influence the outcome. the identification, isolation and the asses...

During spermiogenesis, the histone-to-protamine replacement causes the compaction of the spermatid chromatin. The genes for protamines, PRM-1 and PRM-2, are transcribed in round and elongating spermatids. The transcripts are stored in a translationally-repressed state by the binding of protein repressors before being translated in elongating and elongated spermatids. RNA extracts from homogeniz...
