Changes In The Statistical Properties Of Stochastic Anisotropic Electromagnetic Beams On Propagation In The Turbulent Atmosphere, Xinyue Du, Daomu Zhao, Olga Korotkova

Physics Articles and Papers

We report analytic formulas for the elements of the e 2 X 2 cross-spectral density matrix of a stochastic electromagnetic anisotropic beam propagating through the turbulent atmosphere with the help of vector integration. From these formulas the changes in the spectral density (spectrum), in the spectral degree of polarization, and in the spectral degree of coherence of such a beam on propagation are determined. As an example, these quantities are calculated for a so-called anisotropic electromagnetic Gaussian Schell-model beam propagating in the isotropic and homogeneous atmosphere. In particular, it is shown numerically that for a beam of this class, unlike …

Application Of Correlation-Induced Spectral Changes To Inverse Scattering, Daomu Zhao, Olga Korotkova, Emil Wolf

Physics Articles and Papers

It is shown how the phenomenon of correlation-induced spectral changes generated on scattering of a polychromatic plane wave on a spatially homogeneous random medium may be used to determine the correlation function of the scattering potential of the medium.

Tetraspanin Kai1/Cd82 Inhibits Cell Migration-Related Cellular Events Via Reorganizing Actin Network, Wei Liu

Theses and Dissertations (ETD)

To determine how tetraspanin KAI1/CD82, a tumor metastasis suppressor, inhibits cell migration, we assessed which motility-related cellular events are altered by KAI1/CD82 and how KAI1/CD82 regulates these events. We found that KAI1/CD82-overexpressing cancer cells exhibit various morphologies but typically display elongated cellular extensions and a lack of lamellipodia. Live imaging demonstrated that the formation of lamellipodia and retraction of extensions were deficient upon KAI1/CD82 overexpression.

The deficiency in developing motility-related cellular events was accompanied by defects in actin cortical network and stress fiber formations. Notably, actin polymerization was attenuated by KAI1/CD82. Although Rac1 activity was diminished upon KAI1/CD82 expression, Rac1 …

Enzyme Architecture And Flexibility Affect Dna Topoisomerase I Function, Mariè Van Der Merwe

Theses and Dissertations (ETD)

DNA topoisomerase I (Top1) is a highly conserved enzyme composed of four domains: a positively charged N-terminus; a DNA binding/core domain that circumscribes duplex DNA; a non-conserved linker domain; and a C-terminal/catalytic domain. Top1 catalyzes changes in DNA topology by transient cleavage of a single DNA strand and the concomitant formation of a phosphotyrosyl linkage between the enzyme and the 3’ DNA end. This covalent Top1-DNA complex is the binding site for camptothecin (CPT), which selectively inhibits religation of the cleaved DNA strand. CPT binding stabilizes the covalent complex, while the collision of replication forks with CPT-Top1-DNA adducts produces DNA …

Construction And Analysis Of An Ozone Profile Climatology Over Houston, Texas, Gary A. Morris, Anne M. Thompson, Ryan Perna, John Yorks, Bernhard Rappengluek, Greg Ostermann, Barry Lefer, Renee Boudreaux, Aaron Chow, Bonnie Ford, Elizabeth Thompson, Scott Hersey, Brittni Emery

Physics and Astronomy Faculty Presentations

Since the summer of 2004, over 200 ozonesondes have been launched from the campuses of Rice University or the University of Houston (29.7 N, 95.3 W), each about 3 miles from downtown Houston. These sounding launches have been sponsored by NASA, the Shell Center for Sustainability of Rice University, and the Texas Commissions for Environmental Quality as part of a large effort to understand Houston’s ozone problem. Data from these soundings have provided valuable insight into the seasonal and diurnal variations of the vertical ozone distribution and their relationship to changes in atmospheric conditions. In this presentation, we show annual …

An Integral Philosophy And Definition Of Nursing, Olga F. Jarrin

School of Nursing Scholarly Works

A unifying meta-theory of nursing is suggested, building from the foundation of the AQAL framework. A definition of nursing as situated caring is presented, along with a historical discussion of nursing epistemology and theory for context. Implications for practice, education, and research are also discussed. A unifying meta-theory will enable nurses at both the practical and academic levels to appreciate the complexity and simplicity of nursing, allowing them to articulate confidently what we do and why we do it.

A Regulator Of Dscam Mutually Exclusive Splicing Fidelity, Sara Olson, Yiannis Savva, Jung Park, Brenton R. Graveley

UCHC Articles - Research

The Down syndrome cell adhesion molecule (Dscam) gene has essential roles in neural wiring and pathogen recognition in Drosophila melanogaster. Dscam encodes 38,016 distinct isoforms via extensive alternative splicing. The 95 alternative exons in Dscam are organized into clusters that are spliced in a mutually exclusive manner. The exon 6 cluster contains 48 variable exons and uses a complex system of competing RNA structures to ensure that only one variable exon is included. Here we show that the heterogeneous nuclear ribonucleoprotein hrp36 acts specifically within, and throughout, the exon 6 cluster to prevent the inclusion of multiple exons. Moreover, hrp36 …

The Future Of Television: An Analysis On The Impact Of The Internet On Both National And Local Television, Sarae Rodriguez

Theses & Dissertations

Television has served as the most influential medium in the 20th century. Its popularity soared as programming developed on broadcast TV in the 1950s. Like television, the Internet was developed slowly in stages, over a number of years. Today, both mediums are widely used. However, more people are starting to read, view and download television news and entertainment content on the Internet. In order tor the major networks and local TV stations to transition in the media broadcasting industry, station websites have become a requirement, so viewers may have the alternative to watch television on the Internet. This transition has …

The Potential For Transformation In Second Generation Afghan Women Through Graduate Education, Mahmud Yusuf

Theses & Dissertations

This dissertation examines the educational experiences of Afghan women in graduate education whose parents are Afghan immigrants. Afghan immigrants are from one of the smallest ethnic groups in the United States and have only started arriving here after the 1980s. Their participation in the educational system has gone largely undocumented. Afghan Americans have been educated in the American system by immigrant parents who have had little experience with this system. Data were collected through in-depth interviews with Afghan American women about education, family, ethnicity, and relationships. The women’s experiences are discussed in the interconnected contexts of the Afghan American experience, …

Effects Of An Inserted Endoscope On Chyme Movement In Small Intestine – A Theoretical Model, V. P. Srivastava

Applications and Applied Mathematics: An International Journal (AAM)

The effects of an inserted endoscope on chyme movement in small intestine (gastrointestinal tract) have been investigated. The flow of chyme is induced by a progressive wave of area contraction along the length of intestinal wall under long wavelength approximation. It is found that the chyme movement is significantly influenced due to the presence of the endoscope. The pressure drop assumes lower values for higher values of the endoscope radius for small flow rates but the property reverses with increasing flow rates. The friction forces at intestinal wall and endoscope possess character similar to the pressure drop for any given …

Bayesian Analysis For Penalized Spline Regression Using Win Bugs, Ciprian M. Crainiceanu, David Ruppert, M.P. Wand

Johns Hopkins University, Dept. of Biostatistics Working Papers

Penalized splines can be viewed as BLUPs in a mixed model framework, which allows the use of mixed model software for smoothing. Thus, software originally developed for Bayesian analysis of mixed models can be used for penalized spline regression. Bayesian inference for nonparametric models enjoys the flexibility of nonparametric models and the exact inference provided by the Bayesian inferential machinery. This paper provides a simple, yet comprehensive, set of programs for the implementation of nonparametric Bayesian analysis in WinBUGS. MCMC mixing is substantially improved from the previous versions by using low{rank thin{plate splines instead of truncated polynomial basis. Simulation time …

The Politics Of Vodou: Aids, Access To Health Care And The Use Of Culture In Haiti, Catherine Benoît

Anthropology Faculty Publications

During the past few years, the AIDS campaign in Haiti has been targeting Vodou officiants and organizations. These awareness and training programmes in- form officiants about the transmission and prevention of AIDS, tests for HIV and anti- retroviral drugs, or even try to encourage them to become involved in a medical referral system. These culturalist interventions are grounded in an essentialist concept of culture that can have harmful effects on the targeted groups. The concept of culture underlying such interventions is deconstructed along with the categories of tradi- tional medicine and the ‘tradipractitioner’. An approach to public health is advocated …
