We study the action of G = SL(2,R), viewed as a group definable in the structure M = (R,+,×), on its type space SG(M). We identify a minimal closed G-flow I, and an idempotent r ∈ I (with respect to the Ellis semigroup structure ∗ on SG(M)). We also show that the “ideal group” (r ∗ I, ∗) is nontrivial (in fact it will be the group with 2 elements), yielding a negative answer to a question of Ne...
nowadays, it has demonstrated that viruses can be transmitted by water and foods. therefore, it causes the research to develop for detecting different viruses in water and foods. among foods, milk can transfer potentially pathogenic viruses. on the other hand, to achieve every method for recovery and extraction of viruses in raw milk it needs to know about impact of milk components on viruses. ...
In data envelopment analyze (DEA) the scale efficiency in the input-oriented CCR model is less than or equal to the scale efficiency in DEA based on the fractional analysis (DEA-R). Also, the scale efficiency in case of multiple inputs and one output and vice versa the scale efficiencies are equal in DEA and DEA-R. In this paper, first, DEA-R model with weight restrictions when there is relativ...
