Do correlations create an energy gap in electronic bilayers? Critical analysis of different approaches

This paper investigates the effect of correlations in electronic bilayers on the longitudinal collective mode structure. We employ the dielectric permeability constructed by means of the classical theory of moments. It is shown that the neglection of damping processes overestimates the role of correlations. We conclude that the correct account of damping processes leads to an absence of an energy gap.Comment: 4 page

If jeremiah wrote it, it must be ok: on the attribution of lamentations to jeremiah in early rabbinic texts

Despite the absence of any formal attribution of the book of Lamentations to the prophet Jeremiah in the Hebrew Bible, the rabbis of the Talmudic period chose to perpetuate and reinforce this idea. The question explored is how this benefited them. Using Jorge Gracia’s discussion of the “pseudo-historical author,” the influence of the rabbinic assumption of Jeremiah’s authorship of Lamentations on their exegesis of the book is explored. The rabbis were troubled by a number of theologically challenging verses and the claim of authorship opened the door to their use of the book of Jeremiah to explain away these difficulties

Management Decision Making and Political Viability Criteria in Large Corporate Organizations

This thesis focuses on the magnitude of political viability in managerial decision making in large corporate organizations . Political viability ls defined as perpetuating shrewdness to flourish one\u27s career within an organization. Recent economic conditions and global competitiveness have forced corporations to examine their traditional managerial roles. As a result, many corporations have totally revamped goals and objectives in an attempt to present a clear and unobstructed vision of their mission. Over the last decade research done by organizational psychologists, consultants, independent ·think· tanks, and decision experts have bombasted corporations with many management philosophies . Decision making is an integral part of all these management philosophies and political viability is an integral part of decision-making. The purpose of this study ls to Investigate the possibility, that, within a large corporate organization, managers may bias decision making to ensure harmonious superior-subordinate relationships. Specifically, it ls hypothesized that management decision making ls primarily driven by internal political viability rather than the business objectives in large corporations. Ninety-six (96) managers participated in the evaluation. The subjects were administered a self-assessment survey for the purposes of distinguishing the political viability relationship as related to the subjects\u27 decision making processes. In all, 54 subjects responded for a 56% return ratio. Each respondents\u27 selections were coded and tabulated. A frequency polygon (distribution) for raw scores showed 42.6% of the sample population were conducive to the HO, the null hypothesis, 9.2% were neutral, and 48.2% were presumed conducive to H1, the research hypothesis. The inferential test was a t distribution with 53 degrees of freedom . Based on the critical t value, the obtained t value did not fall into the 5% probability area. Therefore, the null hypothesis could NOT be rejected and It cannot be statistically inferred that political viability exists within management decision- making in large corporations

Fano-like anti-resonances in strongly coupled binary Coulomb systems

Molecular Dynamics (MD) simulations of a strongly coupled binary ionic mixture have revealed the appearance of sharp minima in the species resolved dynamical density fluctuation spectra. This phenomenon is reminiscent of the well-known Fano anti-resonance, occurring in various physical processes. We give a theoretical analysis using the Quasi Localized Charge Approximation, and demonstrate that the observed phenomenon in the equilibrium spectrum is a novel manifestation of the Fano mechanism, that occurs at characteristic frequencies of the system different from the conventional classical Fano frequencies

Single shot parameter estimation via continuous quantum measurement

We present filtering equations for single shot parameter estimation using continuous quantum measurement. By embedding parameter estimation in the standard quantum filtering formalism, we derive the optimal Bayesian filter for cases when the parameter takes on a finite range of values. Leveraging recent convergence results [van Handel, arXiv:0709.2216 (2008)], we give a condition which determines the asymptotic convergence of the estimator. For cases when the parameter is continuous valued, we develop quantum particle filters as a practical computational method for quantum parameter estimation.Comment: 9 pages, 5 image
