It has been shown that the Boltzmann equation for the viscosity of the A-phase of superfluid 3He at low temperatures has the same form as for a normal Ferrni liquid. The viscosity coefficients A, B, C, D and E are derived exactly. The h , parameter plays an important role in determining the temperature dependence of the viscosity coefficients

Pancharatnam’s [1] notion of ‘in-phase’ is the underlying principle of the quantal geometric phase [2, 3]. It is based on the physical condition of maximal interference: the vector representatives |A〉 and |B〉 of two nonorthogonal quantal states A and B are in-phase if they produce a maximum in intensity when added. This amounts to the condition 〈B|A〉 > 0, and any deviation from it defines the P...

Background: To compare the effect of GnRH agonist administration with vaginal progesterone on serum progesterone in Luteal phase in control ovarian hyper stimulation and intrauterine insemination cycles Materials and Methods: In this clinical trial, 242 infertile patients because of UEI (unexplained inferetility candidate for ovarian stimulation and intrauterine insemination reffering to infert...

abstract   introduction: the purpose of present research was the study of the effect of sensory feedback on speed of the relative phase transition in anti-phase bimanual coordination pattern across old adults. materials and methods: therefore 15 intact male old adults selected in available with age range 60-70 years that were all of them hand-right. participants started their movement on bimanu...

Here, we present the first observation of a smectic B (Sm(B)) phase in a system of charged colloidal gibbsite platelets suspended in dimethyl sulfoxide (DMSO). The use of DMSO, a polar aprotic solvent, leads to a long range of the electrostatic Coulomb repulsion between platelets. We believe this to be responsible for the formation of the layered liquid crystalline phase consisting of hexagonal...

Several information-theoretic studies on channels with output quantization have identified the capacity-achieving input distributions for different fading 1-bit in-phase and quadrature (I/Q) quantization. However, an exact characterization of distribution multi-bit phase has not been provided. In this paper, we consider four channel models at identify optimal each model. We first a complex Gaus...

In this work, we analyze the influence of milling device in microstructural evolution two Fe-X-B-Cu (X = Nb, NiZr) alloys produced by mechanical alloying (MA). The devices are a planetary mil (P7) and shaker mill (SPEX 8000). Microstructural analysis X-ray diffraction detects formation Fe rich solid solution. Fe-Nb-B-Cu alloy also appears Nb(B) minor phase, whereas Fe-NiZr-B-Cu mill, disordered...
