Phenomenological implications of an SU(5) × S4 × U(1) SUSY GUT of flavor
No full textWe discuss the characteristic low energy phenomenological implications of an SU (5) supersymmetric (SUSY) grand unified theory whose flavor structure is controlled by the family symmetry S4×U(1), which provides a good description of all quark and lepton masses, mixings as well as charge parity violation. Although the model closely mimics minimal flavor violation (MFV) as shown in M. Dimou, S.?F. King, and C. Luhn, J. High Energy Phys. 02 (2016) 118., here we focus on the differences. We first present numerical estimates of the low energy mass insertion parameters, including canonical normalization and renormalization group running, for well-defined ranges of SUSY parameters and compare the naive model expectations to the numerical scans and the experimental bounds. Our results are then used to estimate the model-specific predictions for electric dipole moments (EDMs), lepton flavor violation (LFV), B and K meson mixing as well as rare B decays. The largest observable deviations from MFV come from the LFV process µ → e γ and the electron EDM

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Transplantation reveals regional differences in oligodendrocyte differentiation in the adult brain
No full textTo examine the role of gray and white matter niches for oligodendrocyte differentiation, we used homo- and heterotopic transplantations into the adult mouse cerebral cortex. White matter-derived cells differentiated into mature oligodendrocytes in both niches with equal efficiency, whereas gray matter-derived cells did not. Thus, white matter promotes oligodendrocyte differentiation, and cells from this niche differentiate more easily, even in the less supportive gray matter environment
NONPERTURBATIVE DYNAMICS OF ATOMS IN STRONG LASER FIELDS - ADIABATIC STABILITY OF HYDROGEN-ATOM
No full textFaisal F, DIMOU L. NONPERTURBATIVE DYNAMICS OF ATOMS IN STRONG LASER FIELDS - ADIABATIC STABILITY OF HYDROGEN-ATOM. In: Acta Physica Polonica A. ACTA PHYSICA POLONICA A. Vol 86. POLISH ACAD SCIENCES INST PHYSICS; 1994: 201-211.Recent investigations of laser-atom interaction at high intensities have led to the discovery of several unexpected phenomena, and their studies have deepened our understanding of non-perturbative dynamics of quantum systems subjected to unusually strong radiation fields. For the analysis and interpretation of these phenomena. We have developed an ab initio non-perturbative method, the Floquet close-coupling method, and applied it to analyse the highly non-perturbative problem of adiabatic stability of hydrogen atom. Ab initio rates of ionization as a function of the laser intensity for the excited circular states as well as related non-circular states are obtained. Our quantitatively accurate results clearly show that the predictions of the previous approximate theories such as the well-known ''high-frequency'' theory are qualitatively similar but differ quantitatively. The analysis of the dependence of adiabatic stability on the principal quantum number, the angular momentum, as well as on the magnetic quantum number for the Rydberg states are complemented by investigations of the behavior of the ground state for frequencies below the ionization threshold. In the latter situation we found the existence of stability windows within which the ionization probability decreases with increasing intensity but outside of which the atom becomes more unstable. It is shown here that the mechanism for the occurrence of stability windows is the self-tuned anti-resonance at specific intensities
