We describe the use of reverse Monte Carlo refinement to extract structural information from angle-resolved data of a Bragg peak. Starting with small-angle neutron scattering data, the positional order of an ensemble of flux lines in superconducting Nb is revealed. We discuss the uncovered correlation functions in the light of topical theories, in particular, the "Bragg glass" paradigm.

We examine the problem of generation mixing in realistic superstring derived standard–like models, constructed in the free fermionic formulation. We study the possible sources of family mixing in these models. In a specific model we estimate the Cabibbo angle. We argue that a Cabibbo angle of the correct order of magnitude can be obtained in these models.

objectives: patellar maltracking is the main reason for pain and disability in patellofemoral pain syndrome (pfps). patellar taping can considerably reduce such pain and disability. this study compared the effectiveness of physiotherapy exercises and kinesio taping on the patellar position in women with pfps (mean age 32.2±1.12 years) by using magnetic resonance imaging (mri). methods: thirty w...

Mixed convection of Cu-Water nanofluid is studied numerically in a shallow inclined enclosure by applying lattice Boltzmann method. The D2Q9 lattice and internal energy distribution function based on the BGK collision operator are used in order to develop the thermal flow field. The enclosure's hot lid has the constant velocity of U0 while its cold lower wall has no motion. Moreover, sidewalls ...

In this paper, we consider the problem of computing, for a given rectilinear angle sequence, a “small” rectilinear polygon. A rectilinear angle sequence S is a sequence of left (90◦) turns and right (270◦) turns, that is, S = (s1, . . . , sn) ∈ {L, R}, where n is the length of S. As we consider only rectilinear angle sequences, we usually drop the term “rectilinear.” A polygon P realizes an ang...

Abstract. Chemical shift tensors in 13C solid-state NMR provide valuable localized information on the chemical bonding environment organic matter, and deviations from isotropic static-limit powder line shapes sensitively encode dynamic-averaging or orientation effects. Studies natural abundance require magic-angle spinning (MAS), where analysis must thus focus sidebands. We propose an alternati...
