The transition amplitude is obtained for free massive particle of arbitrary spin by calculating the path integral in the index–spinor formulation within BFV–BRST approach. None renormalizations of the path integral measure were applied. The calculation has given the Weinberg propagator written in index–free form with the use of index spinor. The choice of boundary conditions on the index spinor...

rainfall erosivity is the ability of rainfall to detach the soil particles. this study was conducted to evaluate spatial variability of rainfall erosivity indices in khouzestan province. the point data of indices (ei30, aim, ke>1 and onchev indices) in 74 stations were used to generate spatial erosivity maps through deterministic and geostatistical interpolation methods (radial basis functions,...

In the open ocean, many animals are highly transparent, some achieving near invisibility. However, little is known about how this transparency is attained. The effects of cellular ultrastructure on tissue transparency were mathematically modeled. Given a specific constant volume or surface area of a higher refractive index material (e.g. protein, lipid, etc.), within a lower refractive index cy...

A distinctive contribution of the unemployment model of Diamond, Mortensen, and Pissarides is the creation of an economically coherent concept of labor-market tightness. In a tighter market, jobseekers find jobs more quickly and employers take longer to fill jobs. The evidence in this paper on individual job-finding rates and on job-filling rates of employers shows that a single index factor de...

Small-angle ( similar10(-3) rad) scattering of light by ocean water is quantitatively analyzed. The two mechanisms that give rise to such scatterings are suspended biological particles having an index of refraction close to that of water and refractive effects due to large-scale (compared to the laser beam diameter) index of refraction variations. Results of recent experiments performed at the ...

The growing use of clusters in diverse applications, many of which have real-time constraints, requires Qualityof-Service (QoS) support from the underlying cluster interconnect. In this paper, we propose an analytical model that captures the characteristics of a QoS capable wormhole router, which is the basic building block of cluster networks. The model captures the behavior of integrated traf...

We study the effects of particle shape on the absorption and scattering cross sections of randomly oriented particles in the Rayleigh domain, i.e. particles that are very small compared to the wavelength of radiation both inside and outside the particle. In particular, we investigate the validity of the so-called statistical approach. In this approach it is assumed that the scattering and absor...
