BUGS for a Bayesian Analysis of Stochastic Volatility Models

This paper reviews the general Bayesian approach to parameter estimation in stochastic volatility models with posterior computations performed by Gibbs sampling. The main purpose is to illustrate the ease with which the Bayesian stochastic volatility model can now be studied routinely via BUGS (Bayesian Inference Using Gibbs Sampling), a recently developed, user-friendly, and freely available software package. It is an ideal software tool for the exploratory phase of model building as any modifications of a model including changes of priors and sampling error distributions are readily realized with only minor changes of the code.

Dynamical Regimes in Semiconductor Superlattice

The method for the calculation of the spectrum of the Lyapunov exponents (LEs) has been proposed for the semiconductor superlattices (SL). Having applied the developed technique to identify the complex regimes observed in SL we have proven the presence of the dynamical chaos.

Local Modifications of Optical Glass by High-Intensity Ultrashort Laser Pulses

Ultrashort pulses are used to modify the structure and optical properties of the optical glasses. Energy of an ultrashort pulse absorbed in a highly nonlinear optical glass is evaluated within an analytical model based on approximate theoretical approach. In our numerical model, Gaussian beam is focused into a glass sample. Dispersion of nonlinear coefficients of refraction and absorption is taken into account.

The Clasterization of Plague Microbe Strains by Multilocus VNTR-Analisis

Plague is a very important social-significant problem of international importance. Solution of this problem needs a creation of new highly-effective tools of diagnostics and prevention of plague. Modern molecular-genetic systems shows high differentiating capabilities relating to different bacterial species such as PCR, sequencing and VNTR – analysis. The purpose of the work is to examine the effectiveness of three VNTR loci – ms01, ms04 and ms46 for clasterization of Yersinia pestis strains on natural focal origin.

Boundary of Generalized Synchronization in Two Unidirectionally Coupled Tunnel Diode Generators

The behavior of the boundary of generalized synchronization in two unidirectionally coupled tunnel diode generators has been studied. Peculiarities in its behavior in the field of the relatively large values of the control parameter mistuning have been found. The character of this behavior and physical mechanisms resulting in the generalized synchronization regime onset in such system have been explained by the analysis of the spectral compound of the signal from response system.
