Multi-component spin-singlet superconductors with competing 0- and $\pi$-pairing couplings, as in $s_{++}$ $s_{\pm}$ phases, are close to instabilities a spontaneous breaking of time-reversal symmetry. We demonstrate that the modification kinetic energy superconducting electrons doubly connected cylinder, determined by applied flux, generally drives transitions from chiral states configurations...

In order to study the elastic–plastic stress field distribution of a double-row-pipe frozen wall, temperature wall is equivalent trapezoidal distribution, and regarded as an thick-walled cylinder with functionally gradient material (FGM) characteristics in radial direction. Considering that elastic modulus cohesion change linearly radius, analysis carried out based on unified strength theory. T...

In this work, thermo – elastic analysis for functionally graded thick – walled cylinder with temperature - dependent material properties at steady condition is carried out. The length of cylinder is infinite and loading is consist of internal hydrostatic pressure and temperature gradient. All of physical and mechanical properties expect the Poisson's ratio are considered as multiplied an expone...

Coaxial nanocables of single-walled carbon nanotubes (SWNTs) sheathed with amorphous silica were synthesized by using an arc discharge method. The as-obtained nanocables were characterized by TEM, SEM and laser Raman. It was found that the nanocalbes are usually tens of microns in length and about 50 nm in diameter, and each of the cylinder-shaped nanocabels contains one to several SWNTs at the...

A thick-walled elastic cylinder contracting symmetrically is used as a model for the myocardium. The active force generated by the myocardium during systolic contraction is represented by body force (force/unit volume of myocardium). A mathematical formalism previously developed and based on large deformation analysis is used to derive a quadratic equation to represent the non-linear pressure v...

Graphene is a one-atom thick planar monolayer of sp-bonded carbon atoms organized in a hexagonal crystal lattice. A single walled carbon nanotube (SWCNT) can be thought of as a graphene sheet rolled up into a seamless hollow cylinder with extremely high length to diameter ratio. Their large surface area, and exceptional optical, mechanical and electronic properties make these low-dimensional ca...

Abstract. A hyperelastic constitutive law, for use in anatomically accurate finite element models of living structures, is suggested for the passive and the active mechanical properties of incompressible biological tissues. This law considers the passive and active states as a same hyperelastic continuum medium, and uses an activation function in order to describe the whole contraction phase. T...
