We study the normal state spectral properties of the fermionic excitations in the Boson-Fermion model. The fermionic single particle excitations show a flattening of the dispersion as the Fermi vector k F is approached from below, forshadowing a Bogoliubov spectrum of a superconducting ground state. The width of the quasiparticle excitations near k F increases monotonically as the temperature i...

SmFeAsO1−xFx was irradiated in a fission reactor by a fast (E > 0.1 MeV) neutron fluence of 4 × 1021 m−2. The introduced defects increased the normal state resistivity due to a reduction in the mean free path of the charge carriers. This leads to an enhancement of the upper critical field at low temperatures. The critical current density within the grains, Jc, increases upon irradiation. The se...

This paper deals with the problem of predicting the average intelligibility of noisy and potentially processed speech signals, as observed by a group of normal hearing listeners. We propose a prediction model based on the hypothesis that intelligibility is monotonically related to the the amount of Shannon information the critical-band amplitude envelopes of the noisy/processed signal convey ab...

A recent experiment has shown “inverted drafting” in flags: the drag force on one flag is increased by excitation from the wake of another. Here we use vortex sheet simulations to show that inverted drafting occurs when the flag wakes add coherently to form strong vortices. By contrast, normal drafting occurs for higher-frequency oscillations, when the vortex wake becomes more complex and mixed...

The next lemma shows that odd and even rescaled squared singular values, sn(R), are monotonically decreasing for n ≥ 0 and monotonically increasing for n ≤ 0. ∗Submitted to the editors July 22, 2016. †Institut für Mathematik, Universität Würzburg, 97074 Würzburg, Germany ([email protected]). ‡Department of Mathematics, University of Washington, Seattle, Washington 98195, U.S.A....

Numerical modelling of the soil in seismic design structures is always a daunting task. The goal this article to develop simplistic numerical technique for shallow founded buildings on compliant soils. An existing large-scale experimental research (TRISEE) was used calibration. physical model comprised rigid square foundation placed sand bed connected column and subjected dynamic sine loading. ...

We build stochastic models for analyzing Jaya and semi-steady-state algorithms. The analysis shows that (a) the maximum expected value of number worst-index updates per generation is a paltry 1.7 regardless population size; (b) size, expectation best-index decreases monotonically with generations; (c) exact upper bounds as well asymptotics best-update counts can be obtained specific distributio...
