The response of a strong bainitic–steel to tempering at high temperatures is investigated, because a softened state is sometimes necessary during the manufacture of engineering components, prior to the final heat–treatment which hardens the material. Thermodynamic calculations conducted to determine the maximum temperature at which the steel could be annealed without forming austenite were foun...

converges when |z| < 1, defining the classical polylogarithm function, equal to − log(1 − z) when s = 1. In general, the behavior of these functions at z = 1 is complicated: it is known, for example, that Lis has an analytic continuation to the cut plane C − 1,∞). The fact that the ‘modified’ polylogarithm of Bloch, Ramakrishnan, Wigner, Wojtkowiak, Zagier, . . . , defined as the real, or imagi...

We present a novel simulation algorithm based on tempering a fraction of relaxation-limiting interactions to accelerate the process of obtaining uncorrelated equilibrium configurations of self-associating polymer solutions. This approach consists of tempering (turning off) the attractive interactions for a fraction of self-associating groups determined by a biasing field h. A number of independ...

We obtain upper bounds on the spectral gap of Markov chains constructed by parallel and simulated tempering, and provide a set of sufficient conditions for torpid mixing of both techniques. Combined with the results of [22], these results yield a two-sided bound on the spectral gap of these algorithms. We identify a persistence property of the target distribution, and show that it can lead unex...

This paper summarizes existing and describes ongoing work on securit ypolicy definition and particularly enforcement in heterogeneous distributed systems. Based on a formal model of operating systems and interactions among networked nodes in a distributed system axiomatizing relations among and abstractions in distributed systems, arbitrary security policies can be defined over the same model; ...

Developing efficient MCMC algorithms is indispensable in Bayesian inference. In parallel tempering, multiple interacting chains run to more efficiently explore the state space and improve performance. The advance independently through local moves, performance enhancement steps are exchange where pause their current sample amongst each other. To accelerate independent they may be performed simul...

A tempered stable Lévy process combines both the α–stable and Gaussian trends. In a short time frame it is close to an α–stable process while in a long time frame it approximates a Brownian motion. In this paper we consider a general and robust class of multivariate tempered stable distributions and establish their identifiable parametrization. We prove short and long time behavior of tempered ...
