Methods of genetic toxicology in the assessment of genomic damage induced by electromagnetic ionizing radiation
Ryzhkin S.; Margulis A.; Kurinenko B.
Medical or occupational exposure of patients and healthcare personnel to ionizing radiation (IR) can be a cause of genetic disorders. In this article we discuss the efficiency of the following tests used to comprehensively assess the effects of ionizing radiation on the genetic apparatus of a cell: The Ames test, the micronucleus test and the FISH method. We provide examples of their use, outline their advantages and drawbacks, estimate the possibility of designing more advanced test systems and discuss requirements for their implementation.

Unified approach to the entropy of an extremal rotating BTZ black hole: Thin shells and horizon limits
Lemos J.; Minamitsuji M.; Zaslavskii O.
© 2017 American Physical Society. Using a thin shell, the first law of thermodynamics, and a unified approach, we study the thermodymanics and find the entropy of a (2+1)dimensional extremal rotating BañadosTeitelbomZanelli (BTZ) black hole. The shell in (2+1) dimensions, i.e., a ring, is taken to be circularly symmetric and rotating, with the inner region being a ground state of the antide Sitter spacetime and the outer region being the rotating BTZ spacetime. The extremal BTZ rotating black hole can be obtained in three different ways depending on the way the shell approaches its own gravitational or horizon radius. These ways are explicitly worked out. The resulting three cases give that the BTZ black hole entropy is either the BekensteinHawking entropy, S=A+4G, or an arbitrary function of A+, S=S(A+), where A+=2πr+ is the area, i.e., the perimeter, of the event horizon in (2+1) dimensions. We speculate that the entropy of an extremal black hole should obey 0≤S(A+)≤A+4G. We also show that the contributions from the various thermodynamic quantities, namely, the mass, the circular velocity, and the temperature, for the entropy in all three cases are distinct. This study complements the previous studies in thin shell thermodynamics and entropy for BTZ black holes. It also corroborates the results found for a (3+1)dimensional extremal electrically charged ReissnerNordström black hole.

Analytical synthesis of a functional observer of the state of a bilinear dynamic system
Asanov A.; Dem’yanov D.
© 2017, Allerton Press, Inc. The problem of asymptotic estimation of a linear combination of the state variables of a bilinear dynamic system using a minimumorder observer is considered. An algorithm for calculating the matrix coefficients of a functional observer using the technology of canonization of matrices is proposed, and solvability conditions for synthesis problem are derived.

Phase space analysis of the accelerating multifluid Universe
Odintsov S.; Oikonomou V.; Tretyakov P.
© 2017 American Physical Society. We study in detail the phase space of a FriedmannRobertsonWalker universe filled with various cosmological fluids that may or may not interact. We use various expressions for the equation of state, and we analyze the physical significance of the resulting fixed points. In addition, we discuss the effects of the stability or an instability of some fixed points. Moreover, we study an interesting phenomenological scenario for which there is an oscillating interaction between the dark energy and dark matter fluid. As we demonstrate, in the context of the model we use, at early times the interaction is negligible, and it starts to grow as the cosmic time approaches the latetime era. Also the cosmological dynamical system is split into two distinct dynamical systems that have two distinct de Sitter fixed points, with the earlytime de Sitter point being unstable. This framework gives an explicit example of the unification of the earlytime with latetime acceleration. Finally, we discuss in some detail the physical interpretation of the various models we present in this work.
