scale insect specimens collected on hordeum sp. (poaceae), dated 24. v. 2003 in khorram abad, lorestan province were identified as exaeretopus tritici williams. this species, which the genus and species is newly recorded from iran, is related to e. harpazi ben-dov, differing mainly in the number of the stigmatic setae and extension of paraopercular pores.

The following four species Physcomitrium pyriforme (Funariaceae), Bryum alpinum, Pohlia elongata (Bryaceae) and Fabronia pusilla (Fabroniaceae), are reported for the first time from Iran. The specimens were collected from Makhmal-kuh mountain (situated in north of Khorram-abad, Lorestan province). The voucher specimens are preserved in the Az-Zahra University herbarium, Tehran, Iran.   

Complex network theory is a useful way to study many real systems. In this paper, an anti-attack model based on complex network theory is introduced. The mechanism of this model is based on dynamic compensation process and reverse percolation process in P2P networks. The main purpose of the paper is: (i) a dynamic compensation process can turn an attacked P2P network into a power-law (PL) netwo...

In this paper, we provide a new MILP modeling to find better/optimal choices of conditional cubes. These choices generally find new or improved attacks against the keyed constructions based on Keccak permutations, including Keccak-MAC, KMAC, Kravatte, Keyak, and Ketje, in terms of attack complexities or the number of attacked rounds. Specifically, we find new key recovery attacks against KMAC12...

A scenario where multiple air vehicles are required to prosecute geographically dispersed targets is considered. Furthermore, multiple tasks are to be successively performed on each target, i.e. the targets must be classified, attacked, and verified as destroyed. The optimal, e.g. minimum time, performance of these tasks requires cooperation amongst the vehicles such that critical timing constr...
