We show how to build up a systematic bosonic field theory for a general reaction-diffusion process involving hard-core particles in arbitrary dimension. We discuss a recent approach proposed by Park, Kim, and Park [Phys. Rev. E 62, 7642 (2000)]. As a test bench for our method, we show how to recover the equivalence between asymmetric diffusion of excluding particles and the noisy Burgers equation.

Scattered intensity measurement is a commonly used method for determining the size of small particles. However, it requires calibration and is subject to errors due to changes in incident irradiance or detector sensitivity. Analysis of two-dimensional scattering patterns offers an alternative approach. We test possible techniques, including morphological image processing operations, on a divers...

objective(s): the silver nanoparticles, being very small size, can permeate the cellular membrane and interfere in the cell's natural process. in the present study, the effects of time, the dosage of these particles and their use on blood molecules and hormones, the volume of drinking water, and the urine parameters were analyzed.materials and methods: thirty six rats of the wistar race, as sub...

A dustiness test has been developed that performs both a single-drop and a continuous rotation test using a 6-g sample. Tests were completed on pigment-grade and ultrafine TiO2, two grades of corundum (Aloxite), yttrium-stabilized zirconia (Y-zirconia) granules, fumed silica, goethite, talc and bentonite. The generated particles were quantified by counting and sizing at 1-s time resolution usin...

In this article we study a charge-conserving finite-element particle scheme for the MaxwellVlasov system that is based on a div-conforming representation of the electric field and we propose a high-order deposition algorithm for smooth particles with piecewise polynomial shape. The numerical performances of the method are assessed with an academic beam test-case, and it is shown that for an app...

We consider a model in which accelerated particles experience line–elements with maximal acceleration corrections that are introduced by means of successive approximations. It is shown that approximations higher than the first need not be considered. The method is then applied to the Kerr metric. The effective field experienced by accelerated test particles contains corrections that vanish in t...

In theories with unstable particles, unitarity is satisfied by the inclusion of only stable states in sums. Hence cuts are not to be taken through particles. This raises a challenge generalized method, whose aim reconstruct amplitudes analyzing sets cuts. Nevertheless, under some general physical conditions, and perhaps methodological modifications, we prove that method still reliable for one-l...
