Diierential cross sections for pp elastic scattering have been measured for very small momentum transfers at six diierent incident antiproton momenta in the range 3.7 to 6.2 GeV/c by the detection of recoil protons at scattering angles close to 90. Forward scattering parameters T , b, and have been determined. For the-parameter, up to an order of magnitude higher level of precision has been ach...

The introduction of internet auction has significantly widened the pool of consumers who participate in auctions and increased the number of companies attempting to sell their products in an auction format. Previous empirical research on auctions has focused almost exclusively on the behavior of professional bidders. In this study, we collect data on a large number of internet auctions to explo...

In integrable field theories the S-matrix is usually a product of a relatively simple matrix and a complicated scalar factor. We make an observation that in many relativistic integrable field theories the scalar factor can be expressed as a convolution of simple kernels appearing in the nested levels of the nested Bethe ansatz. We formulate a proposal, up to some discrete ambiguities, how to re...

1 I n t r o d u c t i o n The combination of different declarative paradigms (specially functional and logic programming) has been widely treated in the literature (see [12] for a survey). Many approaches to the integration of functional and logic programming take constructor-based conditional term rewriting systems as programs. In order to deal properly with non-strict functions, lazy function...

Background: The effectiveness of high-voltage pulsed current (HVPC) treatments in humans as a means of controlling edema and posttraumatic pain has not yet been established. Objective: To analyze the effects of HVPC plus conventional treatment on lateral ankle sprains. Methods: This was a randomized, controlled, double-blind clinical trial with three intervention groups: CG (control group with ...

In terms of social groups, “formalist” syntacticians are roughly those who follow some variant of the program of Generative Grammar (Principles & Parameters, LFG, HPSG, Minimalism, etc.). Their analyses tend to be based on assumptions of Modularity (including the “Autonomy of Syntax” as a special case) and categoriality, among other principles. In more general terms, however, it can be argued t...

One of the most important contributions of A Church to logic is his invention of the lambda calculus We present the genesis of this theory and its two major areas of application the representation of computations and the resulting functional programming languages on the one hand and the representation of reasoning and the resulting systems of computer mathematics on the other hand Acknowledgeme...

Microphysical properties and chemical compositions of aerosol particles determine polarized radiance distribution in the atmosphere. In this paper, the influences of different aerosol properties (particle size, shape, real and imaginary parts of refractive index) on Stokes parameters of polarized skylight in the solar principal and almucantar planes are studied by using vector radiative transfe...

The fixed energy scattering matrix is defined on a perturbed stratified medium, and for a class of perturbations, its main part is shown to be a Fourier integral operator on the sphere at infinity. This is facilitated by developing a refined limiting absorption principle. The symbol of the scattering matrix is shown to determine the asymptotics of a large class of perturbations.

In this work we compare two different approaches to calculation of the three-body resonances on the basis of Faddeev differential equations. The first one is the complex scaling approach. The second method is based on an immediate calculation of resonances as zeros of the three-body scattering matrix continued to the physical sheet.
