The flux-pinning mechanism and activation energy of 10 wt % malic acid-doped MgB2 were investigated by measuring of the critical current density and resistivity as a function of magnetic field and temperature. A crossover field, Bsb, was observed from the single vortex to the small vortex bundle pinning regime. For the sintered sample, the temperature dependence of Bsb(T) at low temperature i...

The expression for the dynamical spectral structure of density fluctuation near QCD critical point has been derived using linear response theory within purview Israel–Stewart relativistic viscous hydrodynamics. change in system as it approaches studied. effects have introduced through a realistic equation state and scaling behaviour various transport coefficients thermodynamic functions. We fou...

We study the influence of global baryon number conservation on non-critical baseline net cumulants in heavy-ion collisions a given acceptance, accounting for asymmetry between mean-numbers baryons and antibaryons. derive probability distribution restricted phase space from canonical partition function that incorporates exact full system. Furthermore, we provide tools to compute any order genera...

We find empirically a characteristic sharp peak-flat trough pattern in a large set of commodity prices. We argue that the sharp peak structure reflects an endogenous inter-market organization, and that peaks may be seen as local “singularities” resulting from imitation and herding. These findings impose a novel stringent constraint on the construction of models. PACS numbers : 01.75+m Science a...
