Among cognitive radio networks there is a persistent trend of competition to acquire under-utilized and idle channels for data transmission. The competition for spectrum resources often results in the misuse of the spectrum resources as networks experience contention in attempt to access unoccupied spectrum bands. The competitive scenario causes cognitive radio networks to incur a huge amount of loss, which constitutes a major problem of self-coexistence among networks. As a way to minimize these losses we present a self-coexistence mechanism that allows cognitive radio networks to coexist with each other by implementing a risk-motivated channel selection based on deference structure. Cognitive radio networks form deference structure community to have more efficient access to a channel of interest and can defer transmission to one another on that channel, thereby minimizing the chances of conflicts. As part of the decision making process to become a member of a deference structure community, cognitive radio networks rely on a risk-motivated channel selection scheme to evaluate the tentative deference structure channel. We provide numerical and simulation results that demonstrates the benefits of the proposed self-coexistence mechanism and show how it helps networks to coordinate their spectrum activities, minimize contention experienced and improve their utility. We also emphasize on the importance of the deference structure community size with regards to the average performance of member networks.

We conducted sexual selection experiments to produce strains with high and low mating discrimination in females of laboratory strains of Hawaiian Drosophila, ***, then examined secondary sexual traits of these two lines, and compared them with that of standard line. In order to do this, we screened out super-males which mated successfully with females and with high mating records;and poor males which usually could not mate successfully with females and had low mating records. In the meantime,choosy females were also screened out, which almost never responded to males' nuptial dance and were difficult to be mated; but indiscriminate females were on the contrary,which were very ready to accept male's nuptial dance and were very easy to be mated. As a result, by mating supermales with choosy females, we were able to produce the high-line strain; similarly, for the low line, we mated poor males with indiscriminate females and we had a strain that was significantly different from our standard strain within just two generations of selection, i.e., morphological trait differences were measured between the standard strain and the two selected lines, which indicated that mating discrimination has affected secondary sexual traits of the lowline strain significantly: Cilia number on the foretibia of low-line males is significantly different from that of the standard line, which perhaps was the indication of incipient speciation in Hawaiian Drosophila.

A multifrontal code is introduced for the efficient solution of the linear system of equations arising from the analysis of structures. The factorization phase is reduced into a series of interleaved element assembly and dense matrix operations for which the BLAS3 kernels are used. A similar approach is generalized for the forward and back substitution phases for the efficient solution of structures having multiple load conditions. The program performs all assembly and solution steps in parallel. Examples are presented which demonstrate the code’s performance on single and dual core processor computers.
