The Iranian Persian chub is an endemic species of the family Cyprinidae known only from few localities in drainages of Southern Iran. It was originally described in the genus Pseudophoxinus as (Pseudophoxinus persidis) and then Petroleuciscus (as Petroleuciscus persidis). In this study, we examined phylogenetic relationships of the Iranian Persian chub with other relatives in the family Cyprini...

Abstract Transboundary water relations in the Euphrates–Tigris (ET) basin are often marked by political confrontation and rivalry between Iraq, Syria Turkey. Even absence of stability, riparian states have remained contact with one another over ET rivers at different levels establishing revitalizing joint governance mechanisms. In these processes, multiple actors—ranging from bureaucracies head...

We present Tigris, a high-performance computation and I/O substrate for clusters of workstations that is implemented entirely in Java. Tigris automatically balances resource load across the cluster as a whole, shielding applications from asymmetries in CPU, I/O, and network performance. This is accomplished through the use of a dataflow programming model coupled with a work-balancing distribute...
