This study presents critical buckling of functionally graded soft ferromagnetic porous (FGFP) rectangular plates, under magnetic field with simply supported boundary condition. Equilibrium and stability equations of a porous rectangular plate in transverse magnetic field are derived. The geometrical nonlinearities are considered in the Love-Kirchhoff hypothesis sense. The formulations are compa...

the entanglement at zero-temperature is studied in a two-qubit xz spin-1/2 chain model in anexternal magnetic field which is applied in the z direction. we have obtained an analytical relation forthe effect of the external magnetic field on the concurrence. it is shown that the ground state of thesystem depends on the strength of exchange coupling. we have shown that the analytical relation oft...

polyhydroxyalkanoates (phas) are naturally occurring polyester that can be accumulated in bacterial cells as a carbon and energy storage compound. they are metabolized by many microorganisms. these biopolymers accumulate in microbial cells under stress conditions such as limitation of nitrogen, phosphate, sulfur, oxygen, and excess carbon source. currently, phas have attracted increasing intere...

2014 Peaks in magnetoresistance at the same magnetic field as the steps in the Hall voltage are observed in (TMTSF)2ClO4. These measurements were performed between 0.1 and 1.2 K, in magnetic fields up to 8.3 T, on a sample having a resistivity ratio R(T = 300 K, H = 0)/R(T ~ 0, H ~ 0) > 1 600. These results are discussed within a model associating the quantum Hall effect with phase transit...

We study the relativistic van Alphen–de Haas effect in cold dense quark matter in a homogeneous magnetic field which arises from oscillations in the effective potential of an underlying extended NJL-model. Finally, we discuss the phase structure of the model in the parameter plane (μ,H) and the solution of the mass gap equation.

We investigate the two-dimensional magnetic operatorHc0,B,β = (−i∇−A) − βδ(.−Γ), where Γ is a smooth loop. The vector potential has the form A = c0 ( −y x2+y2 ; x x2+y2 )

Certain magnetic recording applications call for a large number of sequences whose differences do not include certain disallowed binary patterns. We show that the number of such sequences increases exponentially with their length and that the growth rate, or capacity, is the logarithm of the joint spectral radius of an appropriately defined set of matrices. We derive a new algorithm for determi...
