A new method for constructing maps from radiation hybrid data is proposed. It uses maximization of a pseudo-likelihood based on information from all marker pairs. The pseudo-likelihood is a relatively smooth function of the marker position, allowing us to use gradient-based computational tools. Multi-dimensional scaling is used to provide starting positions for the markers. The method is fully ...
در فرایند نابودی الکترون ـ پوزیترون، تبدیل کوارک ها به هادرون های نهایی به کمک تابع ترکش توصیف می شود. روش های متعددی برای بدست آوردن تابع ترکش روی گستره وسیعی از مقیاس ها وجود دارد. فرضیه scaling ایجاب می کند که این تابع از انرژی مرکز جرم مستقل باشد. تابش گلوئون باعث نقض ویژگی scaling می شود. توزیع تکانه عرضی یک نقش مهم را در نقض scaling توابع ترکش به عهده دارد. در این پایان نامه با استفاده ا...
Recent experimental observations on the ‘bulk’ features of particle production at high (pseudo)rapidities will be reviewed. This kinematic region is of interest mostly because of its relevance to the theoretical description of initial state effects of nuclei at ultrarelativistic energies. Measurements of the charged hadron multiplicity density as well as the pseudorapidity dependence of the ell...
An efficient numerical quadrature is proposed for the approximate calculation of the potential energy in the context of pseudo potential electronic structure calculations with Daubechies wavelet and scaling function basis sets. Our quadrature is also applicable in the case of adaptive spatial resolution. Our theoretical error estimates are confirmed by numerical test calculations of the ground ...
The differential cross section and charge asymmetry for inclusive pp → W ± + X → μ ± ν + X production at √ s = 8 TeV are measured as a function of muon pseudo-rapidity. The data sample corresponds to an integrated lumi-nosity of 18.8 fb −1 recorded with the CMS detector at the LHC. These results provide important constraints on the par-ton distribution functions of the proton in the range of th...
Abstract. Multivariate problems are typically governed by anisotropic features such as edges in images. A common bracket of most of the various directional representation systems which have been proposed to deliver sparse approximations of such features is the utilization of parabolic scaling. One prominent example is the shearlet system. Our objective in this paper is three-fold: We firstly de...
We consider QCD3 with an odd number of flavors in the mesoscopic scaling region where the field theory finite-volume partition function is equivalent to a random matrix theory partition function. We argue that the theory is parity invariant at the classical level if an odd number of masses are zero. By introducing so-called pseudo-orthogonal polynomials we are able to relate the kernel to the k...
abstract to estimate spatial variability of soil hydraulic functions, scaling methods were developed and have been widely used. among these functions, physically based methods have been found more desirable because of possibility of estimating soil hydraulic functions from soil physical properties. in this paper, a new and physically based method has been described for scaling soil hydraulic co...
Gas reservoirs with low permeability (k<0.1 mD) are among the unconventional reservoirs and are commonly termed as "Tight Gas Reservoirs". In conventional gas reservoirs that have high permeability, the flow of gas is basically controlled by the reservoir permeability and it is calculated using the Darcy equation. In these reservoirs, gas flow due to gas diffusion is ignored compared to Dar...
