A new species of Blattisocius Keegan, Blattisocius thaicocofloris n. sp., is described from Thailand from adult females and males, raising to 18 the number of species known in this genus. This is the first species of this genus described from flowers (of Cocos nucifera L.; Arecaceae), although two species, Blattisocius apis Basha & Yousef and Blattisocius apisassociae Chinniah & Mohanasundaram,...

A mathematically simple example of a high-dimensional (many-species) Lotka-Volterra model that exhibits spatiotemporal chaos in one spatial dimension is described. The model consists of a closed ring of identical agents, each competing for fixed finite resources with two of its four nearest neighbors. The model is prototypical of more complicated models in its quasiperiodic route to chaos (incl...

this research was conducted to evaluate the effect of different nitrogen and zinc combination on grain yield and its component in maize by path analysis. this experiment was carried out through split plot based on rcbd, varieties as main plot and fertilizers as sub plot, with three replication at badjgah (experimental farm of shiraz university). nitrogen fertilizer in (120,260 and 400 kg/ha) an...

Maize is one of the most important crops, both worldwide and in Romania, preserving diversity biological material used breeding this plant particular importance. The Agricultural Research Development Station (ARDS) Turda, inbred lines collection includes its own genotypes some obtained as a result germplasm exchanges with other institutions country or abroad. In present study, 575 created at Tu...

planting pattern can be adjusted by changing row spacing and row width, one row and two- row planting and plant interval on rows. in order to obtain the optimum planting pattern of a monogerm hybrid cultivar and its effect on the quantitative and qualitative characteristics of this cultivar, an experiment was conducted in two years (2001-2002) in zarghan area of farsprovince. the measured chara...

Objective: An experiment was conducted at Wondo Genet Agricultural Research Center in the production season of 2013/14 and 2014/15 with the objective of identifying the best combination of intra and inter-row spacing for optimum plant population density of stevia. Methods: The experiment was conducted using five intra-row spacing (20cm, 25cm, 30cm, 35cm, and 40...

Abstract The Pilsung cipher is part of the North Korean Red Star operating system, which was leaked to West in 2014. Initial analysis by Kryptos Logic reported a possibility class weak keys due use pseudo-random diffusion. Following this lead, we analyzed and identified small such keys. We developed techniques for searching key that belongs class. After spending thousands CPU hours, found suppo...

We present a row-by-row (RBR) method for solving semidefinite programming (SDP) problem based on solving a sequence of problems obtained by restricting the n-dimensional positive semidefinite constraint on the matrix X. By fixing any (n − 1)-dimensional principal submatrix of X and using its (generalized) Schur complement, the positive semidefinite constraint is reduced to a simple second-order...
