The equilibration of hot and dense nuclear matter produced in the central region in central Au+Au collisions at √ s = 200A GeV is studied within the microscopic transport model UrQMD. The pressure here becomes isotropic at t ≈ 5 fm/c. Within the next 15 fm/c the expansion of the matter proceeds almost isentropically with the entropy per baryon ratio S/A ≈ 150. During this period the equation of...

Experiments were carried out using a flowing-afterglow Langmuir-probe apparatus to measure rate constants for electron attachment to SF6 and thermal detachment from SF6'. In a recent series of papers, these results were combined with new and existing data on nondissociative and dissociative attachment to SF6 and compared to statistical modeling of the various processes involved in the stabiliza...

The encircled energy fraction and its quantiles, notably the half-energy width, are routinely used to characterize the quality of x-ray optical systems. They are, however, always quoted without a statistical error. We show how nonparametric statistical methods can be used to redress this situation, and we discuss how the knowledge of the statistical error can be used to speed up the characteriz...

Standard methods for describing the intensity distribution of mechanical and acoustic wave fields in the high frequency asymptotic limit are often based on flow transport equations. Common techniques are statistical energy analysis, employed mostly in the context of vibro-acoustics, and ray tracing, a popular tool in architectural acoustics. Dynamical energy analysis makes it possible to interp...

We introduce a new supervised algorithm for image classification with rejection using multiscale contextual information. Rejection is desired in image-classification applications that require a robust classifier but not the classification of the entire image. The proposed algorithm combines local and multiscale contextual information with rejection, improving the classification performance. As ...

Abstract – Time-series of global outgoing radiation fields have been reconstructed for the last 20 years using satellite observations from various space systems including some Russian systems. It was detected that during the past two decades global outgoing longwave radiation (OLR) increased (considerably...

an analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. theoretical anisotropies obtained with the transition state model are compared with their corresponding values deduced from the statistical scission model. the nuclear moment of inertia extracted from the model calculations are compared with their estimat...

In this paper un-binned statistical tools for analyzing the cosmic ray energy spectrum are developed and illustrated with a simulated data set. The methods are designed to extract accurate and precise model parameter estimators in the presence of statistical and systematic energy errors. Two robust methods are used to test for the presence of flux suppression at the highest energies: the Tail-P...

We have initiated an entirely new approach to statistical mechanical models of strongly interacting systems where the configurational parameters and the potential energy function are both constructed so that the canonical partition function can be evaluated analytically. For a simplified model of proteins consisting of a single, fairly short polypeptide chain without cross-links, we can adjust ...
