Existence Of Solutions Of The Classical Yang-Baxter Equation For A Real Lie Algebra, Jorg Feldvoss

University Faculty and Staff Publications

We characterize finite-dimensional Lie algebras over the real numbers for which the classical Yang-Baxter equation has a non-trivial skew-symmetric solution (resp. a non-trivial solution with invariant symmetric part). Equivalently, we obtain a characterization of those finite-dimensional real Lie algebras which admit a non-trivial (quasi-) triangular Lie bialgebra structure.

Identification Of A Cellular Protein That Interacts And Synergizes With The Rta (Orf50) Protein Of Kaposi’S Sarcoma-Associated Herpesvirus In Transcriptional Activation, Shizhen Wang, Shuhong Liu, Ming-Hoi Wu, Yunqi Geng, Charles Wood

Nebraska Center for Virology: Faculty Publications

Lytic reactivation of Kaposi’s sarcoma-associated herpesvirus (KSHV), or human herpesvirus 8, from latency requires transcriptional transactivation by the viral protein RTA encoded by the ORF50 gene. Very little is known about how RTA functions and the cellular factors that may be involved in its transactivation function. Using the yeast two-hybrid system, we have identified a human cellular protein that can interact with KSHV RTA. The cellular protein, referred to as the human hypothetical protein MGC2663 by GenBank, is encoded by human chromosome 19. This protein is 554 amino acids (aa) in size and displays sequence similarity with members of the …

Direct Imaging Of Human Swi/Snf-Remodeled Mono- And Polynucleosomes By Atomic Force Microscopy Employing Carbon Nanotube Tips, Gavin R. Schnitzler, Chin Li Cheung, Jason H. Hafner, Andrew J. Saurin, Robert E. Kingston, Charles M. Lieber

Barry Chin Li Cheung Publications

Chromatin-remodeling complexes alter chromatin structure to facilitate, or in some cases repress, gene expression. Recent studies have suggested two potential pathways by which such regulation might occur. In the first, the remodeling complex repositions nucleosomes along DNA to open or occlude regulatory sites. In the second, the remodeling complex creates an altered dimeric form of the nucleosome that has altered accessibility to transcription factors. The extent of translational repositioning, the structure of the remodeled dimer, and the presence of dimers on remodeled polynucleosomes have been difficult to gauge by biochemical assays. To address these questions, ultrahigh-resolution carbon nanotube tip atomic …

Conceptual Constraints On Thinking About Genocide, David Moshman

Department of Educational Psychology: Faculty Publications

Our thinking is unavoidably constrained by our conceptual structures. To the extent that we reflect on and reconstruct our concepts, however, we can sharpen our thinking. The first section of this article considers the nature of concepts, highlighting a standard distinction between prototype-based and formal concepts.

Drawing on these insights from cognitive psychology, the second section suggests that the ability to recognize and understand genocides is greatly restricted by Holocaust-based conceptions of genocide. In turn one can enhance one’s understanding via the construction and application of formal concepts of genocide.

Extending this argument, I observe in the third section that …

Accommodating Pedestrian And Bicycle Access On Parkers Mill Road From New Circle Road To Man O War Boulevard In Lexington, Lisa Aultman-Hall, Eric Jackson

Kentucky Transportation Center Research Report

In the fall of 2000 the Kentucky Transportation Center (KTC) began a planning study on behalf of the Kentucky Transporta tion Cabinet (KYTC) to investigate the bicycle and pedestrian access on KY 1968 (Parkers Mill Road) from Man O War Boulevard to New Circle Road in Lexington. The 1-mile section has a rural design with two 9-foot lanes, limited 3-foot earth shoulders and adjacent objects in the clear zone making travel on this road uncomfortable for pedestrians and cyclists. Yet this section of Parkers Mill Road represents a line of desired non-motorized travel due to parks, neighborhoods, a local high …

Improving Incident Management Response And Coordination Of Resources, Jennifer R. Walton, Monica L. Barrett, Jerry G. Pigman

Kentucky Transportation Center Research Report

Highway crashes cause a major impact to the transportation network by critically limiting the operational efficiency of the roadway. Traveler delay is the problem most often associated with highway crashes, but by far the most serious problem is the resulting secondary crashes that occur. Another related issue is the danger posed to response personnel serving the public at the scene. The magnitude of these problems is severe. A coordinated plan for managing the scene is needed to reduce the impact of highway crashes and improve the safety for everyone.

Multifractal Analysis Of Memory Usage Patterns, Jonathan Browning Crowell

Graduate Theses, Dissertations, and Problem Reports (ETD)

The discovery of fractal phenomenon in computer-related areas such as network traffic flow leads to the hypothesis that many computer resources display fractal characteristics. The goal of this study is to apply fractal analysis to computer memory usage patterns. We devise methods for calculating the Holder exponent of a time series and calculating the fractal dimension of a plot of a time series. These methods are then applied to memory-related data collected from a Unix server. We find that our methods for calculating the Holder exponent of a time series yield results that are independently confirmed through calculation of the …

Order Effects Of Fear And Pain Induction, Kevin Erik Vowles

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although pain responding and emotional states such as fear are highly correlated and appear to interact, the causal relations between these variables have yet to be fully defined. This study sought to further illuminate these relations by investigating how exposure to one of these states (i.e., pain or fear) affects responding to the other. The order in which participants experienced fearful or painful stimuli was manipulated, as well as fear level (i.e., "low" & "high"). Measures of behavioral escape, heart rate, and verbal reports were obtained throughout four experimental trials, as well as rankings of aversiveness for all stimuli encountered. …

Potential Relations Between Extraversion And Cardiovascular Reactivity During Laboratory Stressors, Brandie K. Taylor

Graduate Theses, Dissertations, and Problem Reports (ETD)

This present study was designed to examine the relation between cardiovascular reactivity to stress and the behaviors of individuals classified as either "extraverts" or "introverts." Although experimental psychophysiological studies have been conducted to examine the relation between extraversion and physiological arousal, little is known about the ways in which extraversion and cardiovascular reactivity to stress are related. According to the optimal arousal theory, both extraverts and introverts would be expected to be more reactive to a social challenge than to a mundane non-social task, with introverts exhibiting greater reactivity to both tasks than extraverts. In contrast, a preferred task model …
