Motivated by the recent observations of the peak effect in high-Tc YBCO superconductors, we reexamine the origin of this unusual phenomenon. We show that the mechanism based on the k-dependence (nonlocality) of the vortex-lattice tilt modulus C44(k) cannot account for the essential feature of the peak effect. We propose a scenario in which the peak effect is related to the melting of Larkin dom...

Cíle: Cílem projektu bylo zjistit, zda znečištění arzenem a kovy ze spalování těžby uhlí mohou ovlivňovat incidenci nemelanomových kožních nádorů (C44) u obyvatel Podkrušnohoří, kde se historicky těžily i polymetalické rudy. Metodika: V GA ČR, probíhajícím v letech 2017-2019 jsme pomocí dotazníků pacientů sledovali vztah faktorů životního prostředí, stylu, ko...

this paper studies housing choice under fuzzy circumstances. in this article, fuzzy distance method is employed for selection process. methodology of housing choice with fuzzy distance approach is based on the minimizing fuzzy distance of features from desired amount under fuzzy condition. meanwhile, in the discrete choice models, housing choice is based on utility maximizing of available optio...

the mechanical properties including elastic stiffness constants as well as bulk modulus of palladium (pd) nanowire were calculated in the constant temperature and pressure (npt), ensemble by molecular dynamics (md) simulation technique. the quantum sutton-chen (q-sc) many-body potential was used to calculate the cohesive energy as well as forces experience by every atoms. the temperature and pr...

A proper understanding of the mechanical behavior clay minerals is crucial importance in earth sciences, soil mechanics, and geotechnical engineering. Although more than seventy percent all clays are mixed layer types, vast majority previous studies devoted to pure clays, which make hydraulic properties widespread mixed-layer (MLC) its role soils little understood, especially most common illite...

We apply the gaussian variational method (GVM) to study the equilibrium statistical mechanics of the two related systems: (i) classical elastic manifolds, such as flux lattices, in presence of columnar disorder correlated along the τ direction (ii) interacting quantum particles in a static random potential. We find localization by disorder, the localized phase being described by a replica symme...
