A simple model of a polypeptide multi-chain layer was designed and studied. Each chain was constructed on a flexible [310] lattice and terminally attached to an impenetrable surface. The chains consisted of hydrophilic and hydrophobic amino acid residues. The force field consisted of the...

The model of a polypeptide chains was designed. The linear chain consisting of amino acid residues was approximated by an alpha carbon chain and embedded to a very flexible [310] lattice. The force field consisted of the long-range contact potential between residues and of the local helical...

Summary We introduce and study no-good-deal valuation bounds defined in terms of expected utility. A utility-based good deal is a payoff whose expected utility is too high in comparison to the utility of its price. Forbidding good deals induces, via duality, restrictions on pricing kernels and...

The reduction of energy consumption for heating and cooling services in the existing building stock is a key challenge for global sustainability today and buildings’ envelopes retrofit is one the main issues. Most of the existing buildings’ envelopes have low levels of insulation, high...

In this work we study the nonequilibrium dynamical properties of an ultra-thin magnetic film model. Previous works on this system revealed the presence of novel dynamical properties that were difficult to interpret within a single physical scenario: on one hand the analysis of the aging...

It is purpose of this paper to evidence, in the behaviour of the Mini-DMS model for the French economy, some stochastic properties which may confirm, strengthen or sometimes contradict the results obtained from the standard simulation analysis, which is purely deterministic. In particular, the...

The one-dimensional XXZ model (s=12) in a transverse field, with uniform long-range interactions among the transverse components of the spins, is studied. The model is exactly solved by introducing the Jordan–Wigner transformation and the integral Gaussian transformation. The complete critical...

A simple model for the dynamics of a granular system under tapping is studied. The model can be considered as a particularization for short taps of a more general one-dimensional lattice model with facilitated dynamics. The steady state reached by the system is discussed and the results are...

We consider the 2D critical Ising model with spatially periodic boundary conditions. It is shown that for a suitable reparameterization of the known Boltzmann weights the transfer matrix becomes a polynomial in the variable csc(4u), u being the spectral parameter. The coefficients of this...

We study the dynamical properties of recently introduced frustrated lattice gas models (IFLG and Tetris) for granular media under gentle shaking. We consider both the case where grains have inter-grain surface interactions other than contact forces and the case where they have not,...
