The general analysis of the reaction , in case longitudinally polarized electron beam, has been performed one-photon-nnihilation approximation, accounting for polarization states final nucleon. This is useful description continuum (non-resonant) and resonant (with different possible vector mesons or excited baryons intermediate virtual Feynman diagrams) contributions. conservation hadron electr...

Let Ñt be a standard compensated Poisson process on [0, 1]. We prove a new characterization of anticipating integrals of the Skorohod type with respect to Ñ , and use it to obtain several counterparts to well established properties of semimartingale stochastic integrals. In particular we show that, if the integrand is sufficiently regular, anticipating Skorohod integral processes with respect t...

The present work investigated early hatching differences in naturally occuring field populations and newly reared populations of potato cyst nematodes from the Canary Islands. Hatching behavior of the two species appears to be distinct, with more juveniles hatched from G. pallida that hatch earlier and over a shorter time than G. rostochiensis. The hatching rate of 3-year-old PCN populations wa...

Inferring the causal structure of a set of random variables from a finite sample of the joint distribution is an important problem in science. Recently, methods using additive noise models have been suggested to approach the case of continuous variables. In many situations, however, the variables of interest are discrete or even have only finitely many states. In this work we extend the notion ...

Ñ Large-Eddy Simulation of In-Cylinder Flows Ñ Advances in physical models, numerical methods, and computational power together have brought large-eddy simulation (LES) to the point where it warrants serious consideration for computing in-cylinder turbulent flows. This article includes: a discussion of LES and how it differs from Reynolds-averaged Navier Stokes (RANS) modeling; motivation for t...

Ñ State of the Art of Multi-Dimensional Modeling of Engine Reacting Flows Ñ An overview is provided of the state of art and future prospects for the use of CFD simulation in engine analysis and design. The aspects covered include geometry handling and mesh generation, numerical solvers, mathematical modeling of key physical phenomena, exploitation of parallel computers and industrial applicatio...

On a closed Riemannian manifold pM, gq, the geodesic heat flow deforms loops through an energydecreasing homotopy uptq. It is known that there is a sequence tn Ñ 8 so that uptnq converges in C to a closed geodesic, but it is also known that convergence fails in general. We show that for a generic set of metrics on M , the heat flow converges for all initial loops. We also show that convergence,...
