 Stability of Hartmann flow with the convective approximation / Kalashnikov, I Yu This research is focused on linear analysis of a plane-parallel flow stability in a transverse magnetic field (Hartmann flow) within a convective approximation. We derive and solve equations describing the perturbation growth. [...] arXiv:1502.07683.- 2015 - Published in : Magnetohydrodynamics: 50 (2014) , pp. 353-359 External link: Preprint

 Review of Some Promising Fractional Physical Models / Tarasov, Vasily E Fractional dynamics is a field of study in physics and mechanics investigating the behavior of objects and systems that are characterized by power-law non-locality, power-law long-term memory or fractal properties by using integrations and differentiation of non-integer orders, i.e., by methods of the fractional calculus. This paper is a review of physical models that look very promising for future development of fractional dynamics.

 Monitoring and optimization of energy consumption of base transceiver stations / Spagnuolo, Antonio ; Petraglia, Antonio ; Vetromile, Carmela ; Formosi, Roberto ; Lubritto, Carmine The growth and development of the mobile phone network has led to an increased demand for energy by the telecommunications sector, with a noticeable impact on the environment. Monitoring of energy consumption is a great tool for understanding how to better manage this consumption and find the best strategy to adopt in order to maximize reduction of unnecessary usage of electricity.

 Relativistic Remnants of Non-Relativistic Electrons / Kashiwa, Taro ; Yamaguchi, Taisuke Electrons obeying the Dirac equation are investigated under the non-relativistic $c \mapsto \infty$ limit. General solutions are given by derivatives of the relativistic invariant functions whose forms are different in the time- and the space-like region, yielding the delta function of $(ct)^2 - x^2$.

 Entropy of finite random binary sequences with weak long-range correlations / Melnik, S S ; Usatenko, O V We study the N-step binary stationary ergodic Markov chain and analyze its differential entropy. Supposing that the correlations are weak we express the conditional probability function of the chain through the pair correlation function and represent the entropy as a functional of the pair correlator.

 Observation of the nuclear magnetic octupole moment of $^{173}$Yb from precise measurements of hyperfine structure in the ${^3P}_2$ state / Singh, Alok K ; Angom, D ; Natarajan, Vasant We measure hyperfine structure in the metastable ${^3P}_2$ state of $^{173}$Yb and extract the nuclear magnetic octupole moment. We populate the state using dipole-allowed transitions through the ${^3P}_1$ and ${^3S}_1$ states. [...] arXiv:1206.1663.- 2015 - 5 p. - Published in : Phys. Rev.

 Constraints on axion and corrections to Newtonian gravity from the Casimir effect / Klimchitskaya, G L ; Mostepanenko, V M Axion is a light pseudoscalar particle of much interest for physics of elementary particles and for astrophysics. We review the recently obtained constraints on axion to nucleon coupling constants following from different experiments on measuring the Casimir interaction.

 Hamilton-Jacobi Formalism for Tachyon Inflation / Aghamohammadi, A ; Mohammadi, A ; Golanbari, T ; Saaidi, Kh Tachyon inflation is reconsidered by using the recent observational data obtained from Planck-2013 and BICEP2. The Hamilton-Jacobi formalism is picked out as a desirable approach in this work, which allows one to easily obtain the main parameters of the model.

 Gravitational Casimir effect / Quach, James Q We derive the gravitonic Casimir effect with non-idealised boundary conditions. This allows the quantification of the gravitonic contribution to the Casimir effect from real bodies. [...] arXiv:1502.07429.- 2015 - 6 p. - Published in : Phys. Rev.

 Elliptical Solutions to the Standard Cosmology Model with Realistic Values of Matter Density / Oztas, Ahmet Mecit ; Smith, Michael L We have examined a solution to the FRW model of the Einstein and de Sitter Universe, often termed the standard model of cosmology, using wide values for the normalized cosmological constant Omega_L and spacetime curvature Omega_k with proposed values of normalized matter density. These solutions were evaluated using a combination of the third type of elliptical equations and were found to display critical points for redshift z, between 1 and 3, when Omega_L is positive.
