A method for rapid detection and characterization of reversible associations of macromolecules in solution is presented. A programmable dual-syringe infusion pump is used to introduce a solution of time-varying composition into parallel flow cells for concurrent measurement of laser light scattering at multiple angles and ultraviolet-visible absorbance. An experiment lasting less than 15 min pr...

We study the influence of solid friction on the structure of the force network sustaining a regular bidimensional granular piling. We show how the mechanical equations describing local equilibrium may couple naturally with a stochastic variable. A Monte Carlo method is designed to extract the force networks satisfying static equilibrium conditions. A statistical ensemble is constructed and we s...

In this paper we study the on and oo-equilibrium properties of the four dimensional Gaussian spin glass. In the static case we determine with more precision that in previous simulations both the critical temperature as well as the critical exponent. In the oo-equilibrium case we settle the general form of the autocorrelation function , and show that is possible to obtain dynamically, for the rs...

We study the dynamics of density fluctuations in purely diffusive systems away from equilibrium. Under some conditions the static density correlation function becomes long-ranged. We then analyze this behavior in the framework of nonequilibrium fluctuating hydrodynamics.

− The study presented in this paper aims to develop a new method for active and reactive power balancing in a four-wire stand-alone microgrid (MG), which feds single phase loads. Two unbalance compensation controllers are used, for active and reactive powers. The compensation is based on a dump load (DL) and a static compensator (STATCOM), which ensure the balance of the active and reactive pow...

The cardiovascular responses to combined static-dynamic effort, postprandial dynamic effort and dynamic effort alone were evaluated by upright bicycle ergometry during equilibrium-gated blood pool scintigraphy in 24 men, mean age 59 ± 8 years, with chronic ischemic heart disease. Combined static-dynamic effort and the postprandial state elicited a peak cardiovascular response similar to that of...
