Feasibility Of Measuring The Shapiro Time Delay Over Meter-Scale Distances, Stefan Ballmer, S. Marka, P. Shawhan

Physics - All Scholarship

The time delay of light as it passes by a massive object, first calculated by Shapiro in 1964, is a hallmark of the curvature of space-time. To date, all measurements of the Shapiro time delay have been made over solar-system distance scales. We show that the new generation of kilometer-scale laser interferometers being constructed as gravitational wave detectors, in particular Advanced LIGO, will in principle be sensitive enough to measure variations in the Shapiro time delay produced by a suitably designed rotating object placed near the laser beam. We show that such an apparatus is feasible (though not easy) to …

Supersymmetric Lattices - A Brief Introduction, Simon Catterall

Physics - All Scholarship

Recently, new theoretical ideas have allowed the construction of lattice actions which are explicitly invariant under one or more supersymmetries. These theories are local and free of doublers and in the case of Yang-Mills theories also possess exact gauge invariance. In this talk these ideas are reviewed with particular emphasis being placed on ${\cal N}=4$ super Yang-Mills theory.

Transit Time Measurements Of Charge Carriers In Disordered Silicons: Amorphous, Nanocrystalline, And Nanoporous, Eric A. Schiff

Physics - All Scholarship

We summarize published hole transit-time measurements for hydrogenated amorphous silicon, microcrystalline silicon, and light-emitting nanoporous silicon in terms of drift mobilities and dispersion parameters. For amorphous and microcrystalline silicon, the anomalously dispersive measurements are broadly consistent with multiple-trapping by bandtail traps with an exponential distribution of energy depths. One unexplained result has been that the trap emission prefactor frequency is about 1000 times smaller in microcrystalline silicon than in amorphous silicon. We present a model incorporating both detailed-balance effects and a previously proposed Meyer–Neldel variation of with trap-depth; the model accounts for the factor 1000. We discuss general trap distributions …

Solvent-Washable Polymer Templated Synthesis Of Mesoporous Materials And Solic-Acid Nanocatalysts In One-Pot, Richard E. Mishler Ii, Ankush V. Biradar, Cole T. Duncan, Eric A. Schiff, Tewodros Asefa

Physics - All Scholarship

We report a new and simple one-pot synthetic method to produce mesoporous silica and nanoporous solid acid catalyst capable of catalyzing pinacole-pinacolone rearrangement and esterification reactions, by preparing a solvent washable phosphonated triblock copolymer template and self-assembling it in the presence of alkoxysilane.

One Of These Things Is Not Like The Other: Art Education And The Symbolic Interaction Of Bodies And Self-Images., James Haywood Rolling

Teaching and Leadership - All Scholarship

This article begins with the premise that self-imagery is constituted as a shape-shifting aggregate of symbolic systems that incorporates the human body itself as one of its representations. At intermittent points of the body’s embodiment of visual culture and tacit social experience, alternative representations accrete into varying symbolic systems, the multiple shapes a self-image may take over a lifetime. Given that social identity is derived from the interaction of various symbolic systems, how do some bodies and self-images come to be taken as that of identities incompatible with most others? In this exploration of the self-image and identity, the author …

A Framework For Managing Engineering Change Propagation, Krishna Reddi, Young Moon

Mechanical and Aerospace Engineering - All Scholarship

Engineering Changes (ECs) are facts of life for any company developing and introducing new products, despite a commonly held notion that they are distractions from normal operation. Companies can become more innovative by utilising ideas from the ECs or by learning how to handle the ECs. This paper presents a framework to manage the ECs effectively, particularly the issue of EC propagation. An EC seldom confines itself to a single change, but triggers other changes in different components. The framework is designed to identify the affected components automatically, capture the required knowledge during the design phase of the product life …

Policy Relevant Heterogeneity In The Value Of Statistical Life: New Evidence From Panel Data Quantile Regressions, Thomas J. Kniesner, W. Kip Viscusi

Center for Policy Research

We examine differences in the value of statistical life (VSL) across potential wage levels in panel data using quantile regressions with intercept heterogeneity. Latent heterogeneity is econometrically important and affects the estimated VSL. Our findings indicate that a reasonable average cost per expected life saved cut-off for health and safety regulations is $7 million to $8 million per life saved, but the VSL varies considerably cross the labor force. Our results reconcile the previous discrepancies between hedonic VSL estimates and the values implied by theories linked to the coefficient of relative risk aversion. Because the VSL varies elastically with income, …

The Value Of Statistical Life: Pursuing The Deadliest Catch, Kurt E. Schnier, William C. Horrace, Ronald G. Felthoven

Center for Policy Research

Observed tradeoffs between monetary returns and fatality risk identify estimates of the value of a statistical life (VSL), inform public policy and quantity preferences for environmental quality, health and safety. To date, few investigations have estimated the VSL associated with tradeoffs between returns from natural resource extraction activities and the fatality risks they involve. Furthermore researchers have been unable to determine whether or not one's VSL is stable across multiple decision environments using revealed preference methods. Understanding these tradeoffs (and the VSL that they imply) may be used to inform resource management policy and safety regulations, as well as our …

Extending The Skill Test For Disease Diagnosis, Shu-Chuan Lin, Paul H. Kvam, Jye-Chyi Lu

Department of Math & Statistics Faculty Publications

For diagnostic tests, we present an extension to the skill plot introduced by Briggs and Zaretski (Biometrics 2008; 64:250–261). The method is motivated by diagnostic measures for osteopetrosis in a study summarized by Hans et al. (The Lancet 1996; 348:511–514). Diagnostic test accuracy is typically defined using the area (or partial area) under the receiver operator characteristic (ROC) curve. If partial area is used, the resulting statistic can be highly subjective because the focus region of the ROC curve corresponds to a set of low false‐positive rates that are chosen by the experimenter. This paper introduces a more …

Common Cyclic Vectors For Unitary Operators, William T. Ross, Warren R. Wogen

Department of Math & Statistics Faculty Publications

In this paper, we determine whether or not certain natural classes of unitary multiplication operators on L²(dƟ) have common cyclic vectors. For some classes which have common cyclic vectors, we obtain a classification of these vectors.

Preferential Utilization Of Nadph As The Endogenous Electron Donor For Nad(P)H:Quinone Oxidoreductase 1 (Nqo1) In Intact Pulmonary Arterial Endothelial Cells, Robert D. Bongard, Brian J. Lindemer, Gary S. Krenz, Marilyn P. Merker

Mathematics, Statistics and Computer Science Faculty Research and Publications

The goal was to determine whether endogenous cytosolic NAD(P)H:quinone oxidoreductase 1 (NQO1) preferentially uses NADPH or NADH in intact pulmonary arterial endothelial cells in culture. The approach was to manipulate the redox status of the NADH/NAD⁺ and NADPH/NADP⁺ redox pairs in the cytosolic compartment using treatment conditions targeting glycolysis and the pentose phosphate pathway alone or with lactate, and to evaluate the impact on the intact cell NQO1 activity. Cells were treated with 2-deoxyglucose, iodoacetate, or epiandrosterone in the absence or presence of lactate, NQO1 activity was measured in intact cells using duroquinone as the electron acceptor, and …

Identification, Individualization, Uniqueness, David H. Kaye

Faculty Scholarship

Criminalists and many forensic scientists concerned with the identification of trace evidence have distinguished between identification and individualization, but they have not distinguished as precisely between individualization and uniqueness. This paper clarifies these terms and discusses the relationships among identification, individualization, and uniqueness in forensic-science evidence.

Dendrites, Topological Graphs, And 2-Dominance, Paul Bankston

Mathematics, Statistics and Computer Science Faculty Research and Publications

For each positive ordinal α, the reflexive and transitive binary relation of α-dominance between compacta was first defined in our paper [Mapping properties of co-existentially closed continua, Houston J. Math., 31 (2005), 1047-1063] using the ultracopower construction. Here we consider the important special case α =2, and show that any Peano compactum 2-dominated by a dendrite is itself a dendrite (with the same being true for topological graphs and trees). We also characterize the topological graphs that 2-dominate arcs (resp., simple closed curves) as those that have cut points of order 2 (resp., those that are not trees).

A Nonlinear Extremal Problem On The Hardy Space, William T. Ross, Stephan Ramon Garcia

Complementary Responses To Mean And Variance Modulations In The Perfect Integrate-And-Fire Model, Joanna R. Wares, Todd W. Troyer

Department of Math & Statistics Faculty Publications

In the perfect integrate-and-fire model (PIF), the membrane voltage is proportional to the integral of the input current since the time of the previous spike. It has been shown that the firing rate within a noise free ensemble of PIF neurons responds instantaneously to dynamic changes in the input current, whereas in the presence of white noise, model neurons preferentially pass low frequency modulations of the mean current. Here, we prove that when the input variance is perturbed while holding the mean current constant, the PIF responds preferentially to high frequency modulations. Moreover, the linear filters for mean and variance …

Background

High density genetic maps of plants have, nearly without exception, made use of marker datasets containing missing or questionable genotype calls derived from a variety of genic and non-genic or anonymous markers, and been presented as a single linear order of genetic loci for each linkage group. The consequences of missing or erroneous data include falsely separated markers, expansion of cM distances and incorrect marker order. These imperfections are amplified in consensus maps and problematic when fine resolution is critical including comparative genome analyses and map-based cloning. Here we provide a new paradigm, a high-density consensus genetic map of …

The Classification Of Simple Lie Algebras In Maple, D. Russell Sadler

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Lie algebras are invaluable tools in mathematics and physics as they enable us to study certain geometric objects such as Lie groups and differentiable manifolds. The computer algebra system Maple has several tools in its Lie Algebras package to work with Lie algebras and Lie groups. The purpose of this paper is to supplement the existing software with tools that are essential for the classification of simple Lie algebras over C.

In particular, we use a method to find a Cartan subalgebra of a Lie algebra in polynomial time. From the Cartan subalgebra we can compute the corresponding root system. …

Biological Sciences Faculty Publications

As part of the Coral Reef Targeted Research (CRTR) Program, a partnership between the Global Environment Facility and the World Bank, our research team examined the recruitment patterns of Caribbean spiny lobster (Panulirus argus) postlarvae among regions in the Caribbean, with a particular focus on Mesoamerica. Our goal was to collect comparable information on postlarval supply among regions and to provide data to test predictions of connectivity generated from a coupled biophysical oceanographic model of lobster larval dispersal. Here we present the results of the postlarval recruitment monitoring program. We monitored the catch of postlarvae on Witham-style collectors …

Individual And Group Performance On Insight Problems: The Effects Of Experimentally Induced Fixation, Christine M. Smith, Emily Bushouse, Jennifer Lord

Peer Reviewed Articles

Recent research has shown that the benefits associated with incubation periods during individual problem solving can be explained in terms of forgetting the material or of any strategy that serves to block progress toward success (e.g., Smith & Blankenship, 1991). While interacting groups reliably outperform individuals on both problem-solving and recall tasks, groups’ superior memory capacity may serve to hinder problem solving, especially when fixation has occurred. In the present study, individuals and three-person groups attempted to solve a set of 20 rebus puzzles on two different occasions. In the first session rebuses were accompanied by “clues,” that were designed …

Fundamentals For Using Geographic Information Science To Measure The Effectiveness Of Land Conservation Projects, Robert G. Pontius Jr., Shaily Menon, Joseph Duncan, Shalini Gupta

Other Scholarly Publications

Some humans spend a tremendous amount of effort to change landscapes from a “natural” state to a “developed” state for a variety of desirable economic uses, such as urban, agriculture, transportation, and mining. Others spend a tremendous amount of effort to prevent such development in order to conserve the landscapes for a variety of important environmental uses, such as biodiversity maintenance, carbon storage, water filtration, and landslide prevention. It would be efficient in theory if a society were to focus its development efforts at locations that give the largest economic utility per area developed, and to focus its conservation efforts …

On Uncertainty, Ambiguity, And Contractual Conditions, Eric L. Talley

Faculty Scholarship

This article uses the recent Delaware Chancery Court case of Hexion v. Huntsman as a template for motivating thoughts about how contract law should interpret contractual conditions in general – and "material adverse event" provisions in particular – within environments of extreme ambiguity (as opposed to risk). Although ambiguity and aversion there to bear some facial similarities to risk and risk aversion, an optimal contractual allocation of uncertainty does not always track the optimal allocation of risk. After establishing these intuitions as a conceptual proposition, I endeavor to test them empirically, using a unique data set of 528 actual material …

Post-Modern Meditations On Punishment: On The Limits Of Reason And The Virtues Of Randomization, Bernard E. Harcourt, Alon Harel, Ken Levy, Michael M. O'Hear, Alice Ristroph

Faculty Scholarship

In this Criminal Law Conversation (Robinson, Ferzan & Garvey, eds., Oxford 2009), the authors debate whether there is a role for randomization in the penal sphere - in the criminal law, in policing, and in punishment theory. In his Tanner lectures back in 1987, Jon Elster had argued that there was no role for chance in the criminal law: “I do not think there are any arguments for incorporating lotteries in present-day criminal law,” Elster declared. Bernard Harcourt takes a very different position and embraces chance in the penal sphere, arguing that randomization is often the only way to avoid …

Reaction of [Re₂(CO)₉(NCMe)] with tri(2-thienyl)phosphine (PTh₃) in refluxing cyclohexane affords three substituted dirhenium complexes: [Re₂(CO)₉(PTh₃)] (1), [Re₂(CO)₈(NCMe)(PTh₃)] (2), and [Re₂(CO)₈(PTh₃)₂] (3). Complex 2 was also obtained from the room-temperature reaction of [Re₂(CO)₈(NCMe)₂] with PTh₃ and is an unusual example in which the acetonitrile and phosphine ligands are coordinated to the same rhenium atom. Thermolysis of 1 and 3 in refluxing xylene …
