Photovoltaic Effect In Bent Quantum Wires In The Ballistic Transport Regime, Yuriy V. Pershin Dr, Carlo Piermarocchi

Faculty Publications

A scheme for the generation of a photocurrent in bent quantum wires is proposed. We calculate the current using a generalized Landauer-Büttiker approach that takes into account the electromagnetic radiation. For circularly polarized light, it is demonstrated that the curvature in the bent wire induces an asymmetry in the scattering coefficients for left and right moving electrons. This asymmetry results in a current at zero bias voltage. The effect is due to the geometry of the wire which transforms the photon angular momentum into translational motion for the electrons. Possible experimental realizations of this scheme are discussed.

A General Imputation Methodology For Nonparametric Regression With Censored Data, Dan Rubin, Mark J. Van Der Laan

U.C. Berkeley Division of Biostatistics Working Paper Series

We consider the random design nonparametric regression problem when the response variable is subject to a general mode of missingness or censoring. A traditional approach to such problems is imputation, in which the missing or censored responses are replaced by well-chosen values, and then the resulting covariate/response data are plugged into algorithms designed for the uncensored setting. We present a general methodology for imputation with the property of double robustness, in that the method works well if either a parameter of the full data distribution (covariate and response distribution) or a parameter of the censoring mechanism is well approximated. These …

Grid-Enabling A Vibroacoustic Analysis Application, Brian Bentow, Jon Dodge, Aaron Homer, Christopher D. Moore, Robert M. Keller, Matthew T. Presley, Robert Davis, Jorge Seidel, Craig Lee, Joseph Betser

All HMC Faculty Publications and Research

This paper describes the process of grid-enabling a vibroacoustic analysis application using the Globus Toolkit 3.2.1. This is the first step in a project intended to grid-enable a suite of tools being developed as a service-oriented architecture for spacecraft telemetry analysis. Many of the applications in the suite are compute intensive and would benefit from significantly improved performance. In this paper we show the advantage of using Globus to grid-enable a single tool in a vibroacoustic analysis flow, with the result that using as few as eleven nodes, that tool’s runtime improved by a factor of eight. While communication overhead …

Hispanic Physicians' Tobacco Intervention Practices: A Cross-Sectional Survey Study, Francisco G. Soto Mas, Richard L. Papenfuss, Holly E. Jacobson, Chiehwen E. Hsu, William M. Kane

Faculty, Staff and Student Publications

Background U.S. Hispanic physicians constitute a considerable professional collective, and they may be most suited to attend to the health education needs of the growing U.S. Hispanic population. These educational needs include tobacco use prevention and smoking cessation. However, there is a lack of information on Hispanic physicians' tobacco intervention practices, their level of awareness and use of cessation protocols, and the type of programs that would best address their tobacco training needs. The purpose of this study was to assess the tobacco intervention practices and training needs of Hispanic physicians.

Methods Data was collected through a validated survey instrument …

Developing A Spectral And Colorimetric Database Of Artist Paint Materials, Yoshio Okumura

Theses

As the project of the author's Master's thesis, the development of a spectral and colorimetric database of artist paint materials for acrylic paints was started. The goal of this research project was to: - provide the academic resource of colorant spectral characteristics - give scientifc explanations on various paint-particular phenomena (paint mixing, gloss effects and color gamut expansion by varnishing) These tasks were planned to satisfy possible interests on paint research from not only conservators in museums but also color educators in schools and color reproduction engineers in imaging companies.

Social Structure And Social Learning In Delinquency: A Test Of Akers’ Social Structure-Social Learning Model, Stephen W. Verrill

USF Tampa Graduate Theses and Dissertations

Social learning theory (Akers, 1973, 1977, 1985, 1998; Burgess & Akers, 1966) is an established general theory of criminal, deviant, and conforming behavior that finds substantial empirical support (e.g., Akers, Krohn, Lanza-Kaduce & Radosevich, 1979; Akers, La Greca, Cochran & Sellers, 1989; Alarid, Burton & Cullen, 2000; Krohn, Skinner, Massey & Akers, 1985). Although the theory provides insight into the processes that influence criminal behavior, the theory does not speak to the environments that produce such behavior--the domain of structural theories.

Akers (1998) has suggested that social learning theory accounts for differences in crime rates through its mediation of structural …

Structural And Chiroptical Properties Of The Two Coordination Isomers Of Ybdota-Type Complexes, Lorenzo Di Bari, Gennaro Pescitelli, A. Dean Sherry, Mark Woods

Chemistry Faculty Publications and Presentations

Studies of the structural, physical, and chemical properties of the lanthanide(III) complexes of DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) and related ligands are often complicated by the presence of two coordination isomers in solution. Since these coordination isomers are in exchange and cannot be separated, many techniques offer information only on the weighted average of the two isomers. Lanthanide ion complexes formed with the ligands S(RRRR)NO₂BnDOTMA and S(SSSS)NO₂BnDOTMA preferentially adopt only one of the two common coordination isomers in solution, so the ytterbium complexes of these ligands offer a unique opportunity to study …

Estimating A Treatment Effect With Repeated Measurements Accounting For Varying Effectiveness Duration, Ying Qing Chen, Jingrong Yang, Su-Chun Cheng

UW Biostatistics Working Paper Series

To assess treatment efficacy in clinical trials, certain clinical outcomes are repeatedly measured for same subject over time. They can be regarded as function of time. The difference in their mean functions between the treatment arms usually characterises a treatment effect. Due to the potential existence of subject-specific treatment effectiveness lag and saturation times, erosion of treatment effect in the difference may occur during the observation period of time. Instead of using ad hoc parametric or purely nonparametric time-varying coefficients in statistical modeling, we first propose to model the treatment effectiveness durations, which are the varying time intervals between the …

Implementation Of Operational Framework In The Nlp (Based On Mof And Itil Standards), James Kapp

Regis University Student Publications (comprehensive collection)

An operational framework, as proposed by the Microsoft Operational Framework (MOF) and the Information Technology Infrastructure Library (ITIL) provides a process model for controlling and managing Information Technology (IT) operations. With a strict focus on IT operations, it provides the processes and terminology to coordinate and integrate the functional elements of an IT department. The Systems Engineering and Applications Development (SEAD) practicum is composed of four main groups; Data Access, Network, Integrated Services and Development. This professional project will propose the beginning framework for overall operation and integration of the SEAD Practicum with an emphasis on service support and documentation. …

Inhibition Of Cellular Respiration By Doxorubicin, Zhimin Tao, Henry G. Withers, Harvey S. Penefsky, Jerry Goodisman, Abdul Kader Souid

Chemistry - All Scholarship

Doxorubicin executes apoptosis, a process known to produce leakage of cytochrome c and opening of the mitochondrial permeability transition pores. To define the loss of mitochondrial function by apoptosis, we monitored cellular respiration during continuous exposure to doxorubicin. A phosphorescence analyzer capable of stable measurements over at least 5 h was used to measure [O(2)]. In solutions containing glucose and cells, [O(2)] declined linearly with time, showing that the kinetics of oxygen consumption was zero order. Complete inhibition of oxygen consumption by cyanide indicated that oxidations occurred in the respiratory chain. A decline in the rate of respiration was evident …

Detection Avoidance, Chris William Sanchirico

ExpressO

In practice, the problem of law enforcement is half a matter of what the government does to catch violators and half a matter of what violators do to avoid getting caught. In the theory of law enforcement, however, although the state’s efforts at "detection" play a decisive role, offenders’ efforts at "detection avoidance" are largely ignored. Always problematic, this imbalance has become critical in recent years as episodes of corporate misconduct spur new interest in punishing process crimes like obstruction of justice and perjury. This article adds detection avoidance to the existing theoretical frame with an eye toward informing the …

Modeling Differentiated Treatment Effects For Multiple Outcomes Data, Hongfei Guo, Karen Bandeen-Roche

Johns Hopkins University, Dept. of Biostatistics Working Papers

Multiple outcomes data are commonly used to characterize treatment effects in medical research, for instance, multiple symptoms to characterize potential remission of a psychiatric disorder. Often either a global, i.e. symptom-invariant, treatment effect is evaluated. Such a treatment effect may over generalize the effect across the outcomes. On the other hand individual treatment effects, varying across all outcomes, are complicated to interpret, and their estimation may lose precision relative to a global summary. An effective compromise to summarize the treatment effect may be through patterns of the treatment effects, i.e. "differentiated effects." In this paper we propose a two-category model …

Palladium-Imidazolium Carbene Catalyzed Heck Coupling Reactions And Synthesis Of A Novel Class Of Fluoroanthracenylmethyl Ptc Catalysts, Jiuqing Zhang

Theses and Dissertations

Palladium catalyzed Heck coupling with aryl and alkenyl halides has become a powerful means of carbon-carbon bond formation. This standard synthetic method has been developed to a high level of utility using various catalysts, conditions and substrates. Yet significant drawbacks remain, including poor reactivity, the need for high temperatures and base, limited substrate generality, and selectivity. Mixed products often suffer from olefin migration following insertion. N-Heterocyclic carbenes (NHC) have proven to be electron-rich donors which provide higher stability and reactivity than phosphines. In a previous paper reported by our research group the imidazolium-palladium carbene has proven to be highly efficient …

Facing An Uncertain Future: An Investigation Of The Preparation And Readiness Of First-Time Superintendents To Lead In A Democratic Society, Theodore J. Kowalski, George J. Peterson, Lance D. Fusarelli

Educational Leadership Faculty Publications

The preparation of superintendents is a critical component, an essential element, of systemic education reform, although as (Cooper, Fusarelli, Jackson, & Poster, 2002) observed, “the process is rife with difficulties,” including synchronization of preparation and actual practice, the theory-practice disconnect, the need for life-long learning, and development of an adequate knowledge base (Cooper et al., 2002, p. 242).

The vast majority of research on the efficacy of administrator preparation programs focuses on principals. Most doctoral programs in educational administration serve as de facto preparation programs for superintendents, even though some contain little coursework specifically tailored for the position (Andrews & …
