Ionic conductivity data and structural relaxation times for poly(phenyl glycidyl ether)-co-formaldehyde (PPGE) are compared for the supercooled liquid under a wide range of temperatures and pressures. Conformance to the fractional Debye–Stokes–Einstein (fDSE) relation was observed under all conditions. The fDSE exponent, =0.81, provides an estimate of the relative magnitude of the activation vo...

We study nonequilibrium charge transport in a double-barrier Josephson junction, including nonstationary phenomena, using the time-dependent quasiclassical Keldysh Green’s function formalism. We supplement the kinetic equations by appropriate time-dependent boundary conditions and solve the time-dependent problem in a number of regimes. From the solutions, current-voltage characteristics are de...

The effects connected with the intermolecular relaxation in the coupled nuclear systems are studied theoretically. It was shown that, because of general properties of nuclear-spin systems, the number of parameters necessary to describe the relaxation process is reduced reduced substantially. Moreover, the structure of nuclear system and the relaxation process parameters are to a large extent se...

purpose :   this study was designed to compare the effects of two different relaxation techniques, namely progressive muscle relaxation (pmr) and autogenic relaxation (agr) on moods of young soccer players . methods :   sixteen adolescent athletes (mean age: 14.1 ± 1.3) received either pmr or agr training. using profile of mood states-adolescents, their mood states were measured one week before...

Abstact: The aims of this study were to validate the efficacy of progressive muscular relaxation technique to relieve symptoms of premenstrual syndrome and to evaluate cardiovascular and respiratory parameters that may serve as objective measures of the efficacy of progressive muscular relaxation. A total 90 participants were randomly assigned to group A an experimental group, group B as contro...

Spintronics attracts much attention because of the potential to build novel spin-based devices which are superior to nowadays charge-based microelectronic devices. Silicon, the main element of microelectronics, is promising for spin-driven applications. Understanding the details of the spin propagation in silicon structures is a key for building novel spin-based nanoelectronic devices. We inves...

Aspects of magnetic resonance relaxation measurements in human tissues are discussed. The influence of pulse sequences and parameters are compared and analyzed for different tissues. By controlling the acquisition parameters and data fitting the relaxation rate can be useful in several clinical situations. The influence of repetition and echo time, predicted in sequences of signal acquisition, ...

We studied the massive scalar wave propagation in the background of Reissner-Nordström black hole by using numerical simulations. We learned that the value Mm plays an important role in determining the properties of the relaxation of the perturbation. For Mm≪ 1 the relaxation process depends only on the field parameter and does not depend on the spacetime parameters. For Mm ≫ 1, the dependence ...

A modulated holding beam shining a VCSEL above threshold can improve modulation bandwidth by adjusting the semiconductor laser’s relaxation oscillation frequency. The improved modulation characteristics are accompanied by reduced damping rate. By choosing correct parameters, dynamical behavior of system and cavity solitons is changed.
