Social responsibility of pastoralists is one of the most important elements and an integral part of rangelands exploitation. It not only leads to better rangeland health, but also enhances exploiters’ satisfaction for continuous sustainable utilization of rangelands. The present study investigated the role of social responsibility in rangelands condition in nomadic areas of Gonbad County in Gol...

The persistence of mutualisms despite the strong incidence of exploiters could be explained if exploiters deny one or more services (i.e., cheat) while eventually supplying some subtler but critical services. Pulp feeders usually ingest fruit reward without dispersing seeds and thus are considered to be mainly cheaters or thieves of seed-disperser mutualisms. By consuming the fruit pulp, howeve...

We consider the population dynamics of two competing species sharing the same resource, which is modeled by the carrying capacity term of logistic equation. One species (farmer) increases the carrying capacity in exchange for a decreased survival rate, while the other species (exploiter) does not. As the carrying capacity is shared by both species, farmer is altruistic. The effect of continuous...

WARNING: FLUDARA FOR INJECTION should be administered under the supervision of a 6 qualified physician experienced in the use of antineoplastic therapy. FLUDARA FOR 7 INJECTION can severely suppress bone marrow function. When used at high doses in dose8 ranging studies in patients with acute leukemia, FLUDARA FOR INJECTION was associated 9 with severe neurologic effects, including blindness, co...

Turing structures, standing waves, oscillatory clusters, and accelerating waves have been found in the spatially extended Belousov-Zhabotinsky system dispersed in water droplets of a reverse AOT microemulsion. The variety of patterns is determined by the tunable microstructure of the medium, i.e., by the concentration and size of water droplets. We propose a simple model to describe this system.

Sympatric speciation can arise as a result of disruptive selection with assortative mating as a pleiotropic by-product. Studies on host choice, employing artificial neural networks as models for the host recognition system in exploiters, illustrate how disruptive selection on host choice coupled with assortative mating can arise as a consequence of selection for specialization. Our studies demo...

We propose a general model underlying the problem of designing trading strategies that leak no information to frontrunners and other exploiters. We study major scenarios in the market and design a family of algorithms that can be proven to leak no information in important scenarios. These algorithms can serve as building blocks for more challenging real-world scenarios beyond our current scope....
