A bstract We investigate the effect of superradiant scattering gravitational perturbations on stability rotating black strings, focusing six dimensional equal-spinning Myers-Perry string. find that rapidly strings are unstable to modes within a bounded range string lengths. The instability occurs because momentum along direction creates potential barrier allows for confinement modes. Yet, five ...

In this paper, we obtain the metric of space-time generated by a charged and rotating gravitational body surrounded loud strings, namely, Kerr–Newman black hole with addition cloud strings. background, find radial solutions Dirac equation for massive particles show that they are given in terms Generalized Heun functions. The dependence these on parameter codifies presence strings is pointed out.

In this paper, by applying three functional operators the previous results on the (Poisson) variance of the external profile in digital search trees will be improved. We study the profile built over $n$ binary strings generated by a memoryless source with unequal probabilities of symbols and use a combinatorial approach for studying the Poissonized variance, since the probability distribution o...

Iran's proved natural gas reserves are the world's second largest reserves. Mainly, because of different climate changes and different reservoirs characterizations, studying the behavior of producing outcome fluids and their transportation, is of major interest. One of the main problems occur in the gas reservoirs is related to the hydrate formation while producing from a well, either in produc...

objective: the usage of pesticides has increased during the recent years. one the other hand, presence of harmful pesticides residue in rice and other food has caused a great concern among the consumers. therefore, it is important to develop some pragmatic procedures to increase the food safety along with the reduction in consumption of pesticide residues. methods: a gas chromatograph with elec...

The two previous papers in this series introduced a class of infinite binary strings, called two-pattern strings, that constitute a significant generalization of, and include, the much-studied Sturmian strings. The class of two-pattern strings is a union of a sequence of increasing (with respect to inclusion) subclasses TPλ of two-pattern strings of scope λ, λ = 1, 2, · · · . Prefixes of two-pa...
