Relaxation Decoupling in Metallic Glasses at Low Temperatures.

Upon cooling, glass-forming liquids experience a dynamic decoupling in the fast β and slow α process, which has greatly influenced glass physics. By exploring an extremely wide temporal and temperature range, we find a surprising gradual change of the relaxation profile from a single-step to a two-step decay upon cooling in various metallic glasses. This behavior implies a decoupling of the rel...

Electrical conductivity anomaly in silver vadadium-tellurite glasses at temperatures higher than a characteristic temperature: evidence for an ionic-nonadiabatic polaronic mixed conduction

Electrical conduction anomaly was observed in the mixed ion-polaron regime for xAg2O-40TeO2-(60-x)V2O5 glassy system with 0 ≤x≤ 50 mol%, which were prepared by common melt quenching method. For the understudied glasses, the temperature dependence of dc electrical conductivity was measured from a characteristic temperature to 380 K, which certified their semiconducting nature. The measured condu...

Monte Carlo Simulations of Vector Spin Glasses at Low Temperatures

In this paper I report results for simulations of the three-dimensional gauge glass and the four-dimensional XY spin glass using the parallel tempering Monte Carlo method at low temperatures for moderate sizes. The results are qualitatively consistent with earlier work on the threeand four-dimensional Edwards-Anderson Ising spin glass. I find evidence that large-scale excitations may cost only ...

Two-Component-System Histidine Kinases Involved in Growth of Listeria monocytogenes EGD-e at Low Temperatures.

Two-component systems (TCSs) aid bacteria in adapting to a wide variety of stress conditions. While the role of TCS response regulators in the cold tolerance of the psychrotrophic foodborne pathogen Listeria monocytogenes has been demonstrated previously, no comprehensive studies showing the role of TCS histidine kinases of L. monocytogenes at low temperature have been performed. We compared th...
