Effective Field Theory Program For Conformal Quantum Anomalies, Horacio E. Camblong

Physics and Astronomy

The emergence of conformal states is established for any problem involving a domain of scales where the long-range SO(2,1) conformally invariant interaction is applicable. Whenever a clear-cut separation of ultraviolet and infrared cutoffs is in place, this renormalization mechanism is capable of producing binding in the strong-coupling regime. A realization of this phenomenon, in the form of dipole-bound anions, is discussed.

Rank Distribution In A Family Of Cubic Twists, Mark Watkins

Mathematics - All Scholarship

In 1987, Zagier and Kramarz published a paper in which they presented evidence that a positive proportion of the even-signed cubic twists of the elliptic curve x³+y³=1 should have positive rank. We extend their data, showing that it is more likely that the proportion goes to zero.

Circular Dichroism In Classical Coulomb Scattering Involving Bremsstrahlung, A. A. Krylovetsky, N. L. Manakov, S. I. Marmo, Anthony F. Starace

Department of Physics and Astronomy: Faculty Publications

Classical orbit derivations of the triply differential cross section for electron bremsstrahlung (BrS) in a Coulomb field are presented; the classical origin of the circular dichroism effect in the electron scattering angular distributions is established for both spontaneous and laser-stimulated BrS.

Activation Of Carboplatin By Carbonate, Anthony J. Di Pasqua, Jerry Goodisman, Deborah J. Kerwood, Bonnie B. Toms, James C. Dabrowiak

Chemistry - All Scholarship

Carboplatin, [Pt(NH3)2(CBDCA-O,O')], 1, where CBDCA is cyclobutane-1,1-dicarboxylate, is in wide clinical use for the treatment of ovarian, lung, and other types of cancer. Because carboplatin is relatively unreactive toward nucleophiles, an important question concerning the drug is the mechanism by which it is activated in vivo. Using [1H,15N] heteronuclear single quantum coherance spectroscopy (HSQC) NMR and 15N-labeled carboplatin, we show that carboplatin reacts with carbonate ion in carbonate buffer to produce ring-opened products, the nature of which depends on the pH of the medium. The assignment of HSQC NMR resonances was facilitated by studying the reaction of carboplatin in strong …

Further Studies Of Single-Sided Charge-Sharing Czt Strip Detectors, B Donmez, John R. Macri, Mark L. Mcconnell, James M. Ryan, Mark Widholm, T Narita, L A. Hamel

Space Science Center

We report progress in the study of a thick CZT strip detector module designed to perform gamma-ray spectroscopy and 3-D imaging. We report preliminary performance measurements of 7.5 mm thick single-sided charge-sharing strip detector prototype devices. This design features both row and column contacts on the anode surface. This electron-only approach addresses problems associated with poor hole transport in CZT that limit the thickness and energy range of double-sided strip detectors. This work includes laboratory and simulation studies aimed at developing compact, efficient, detector modules for 0.05 to 1 MeV gamma measurements while minimizing the number and complexity of the …

Importance Resampling For Global Illumination, Justin F. Talbot

Theses and Dissertations

This thesis develops a generalized form of Monte Carlo integration called Resampled Importance Sampling. It is based on the importance resampling sample generation technique. Resampled Importance Sampling can lead to significant variance reduction over standard Monte Carlo integration for common rendering problems. We show how to select the importance resampling parameters for near optimal variance reduction. We also combine RIS with stratification and with Multiple Importance Sampling for further variance reduction. We demonstrate the robustness of this technique on the direct lighting problem and achieve up to a 33% variance reduction over standard techniques. We also suggest using RIS as …

1,3-Bis(9-Ethyl­Carbazol-3-Yl)Propane, Erol Asker, John Masnovi

Chemistry Faculty Publications

In the title compund, C₃₁H₃₀N₂, π–π overlap is absent in the region where carbazole groups of two adjacent mol­ecules are inclined toward each other. The eth­yl groups which protrude from the plane of the carbazole groups and the alkyl­ene chain connecting the two carbazole groups are responsible for the poor mol­ecular stacking.

Loss Functions And Framework For Regional Flood Damage Estimation In Residential Area, Jui-Lin Kang, Ming-Daw Su, Ling-Fang Chang

Journal of Marine Science and Technology–Taiwan

The risks of flooding damages for a region increase as the population and economy development increased in that area. Damage assessment and risk analysis are important issues for risk management and hazard mitigation. There are huge amount of data involved in the process of regional damage assessment and most of these data are spatially and temporally distributed. This paper focuses on the use of spatial data for capture of spatial characteristics of damage in natural calamities. Because it affects a large number of persons and families, flood damages in the residential area usually attract major attentions in regional flood hazard …

Effects Of Closure Models On Supercavitating Bubble Development, Bin-Chen Wu, Jiahn-Horng Chen

Journal of Marine Science and Technology–Taiwan

Effects of different cavity closure models on the development sheet supercavitation of two-dimensional hydrofoils were examined in this report. The study was carried out under the assumption of potential flow for which a cavity closure model was needed. A potential-based boundary element method has been developed for this purpose. The models we employed included the constant velocity model and the short plate termination model. Several different airfoil shapes were tested. Their effects on the cavity shape, lift coefficient, cavity volume and computation efficiency were studied. Careful investigations show that closure models have insignificant influence on physical quantities, but do have …

Furthermore, based on the Structured Query Language (SQL) Command and adopting the technology of Active Server Pages (ASP) and Active Data Object (ADO), a three-tier maritime …

A Study Of Non-Linear Vibrational Behavior Of Cracked Structures By The Finite Element Method, Tzuo-Liang Luo, James Shih-Shyn Wu, Jui-Pin Hung

Journal of Marine Science and Technology–Taiwan

Numerical and experimental investigations provide a link to the location and size of cracks caused by natural vibrations. Cracks may generally result in the variation of structural stiffness and hence enable structures to vibrate nonlinearly. In order to understand the vibrational behavior of crack structures accurately, the study proposes a general and efficient algorithm based on the finite element assumptions and the bilinear vibrational theory. All formulae are derived from the time domain properly and may apply to the overall non-linear motion cycle completely. The contact effect is also considered by introducing the degree of penetration on the cracked surface. …

A Grid-Based Gis Approach To Regional Flood Damage Assessment, Ming-Daw Su, Jui-Lin Kang, Ling-Fang Chang, Albert S Chen

Journal of Marine Science and Technology–Taiwan

Regional flood risk assessment is the base for a sound and comprehensive risk planning or management. The regional flood loss is the sum of the damages in all the flooded parcels. The data involved in this process are multifarious and difficult to establish and maintain especially in the developing countries that suffer most often from the flood hazard. A grid-based GIS approach to regional flood damage assessment is proposed in this paper. Aggregated census data that are relatively available were used instead of the data at parcel level. An algorithm was proposed to disaggregated these aggregated census data into spatially …

Electrochemical Attachment Of Motile Bacterial Cells To Gold, Sergey Rozhok, Richard C. Holz

Chemistry Faculty Research and Publications

Selective attachment of Escherichia coli K-12 bacterial cells to charged gold surfaces was demonstrated. Electrostatic binding of E. coli K-12 bacterial cells to positively charged surfaces was observed starting at +750 mV. The binding of E. coli K-12 cells to positively charged gold surfaces is proposed to occur due to long-range electrostatic interactions between the negatively charged O-chain of lipopolysaccharide (LPS) molecules protruding the bacterial cell body and the electrode surface. Removing LPS alters the cellular surface charge and results in cellular attachment to negatively charged surfaces. Thus, applying an electrical potential allows for the direct, real time detection of …

Persistent And Radiation-Induced Currents In Distorted Quantum Rings, Yuriy V. Pershin Dr, Carlo Piermarocchi

Faculty Publications

Persistent and radiation-induced currents in distorted narrow quantum rings are theoretically investigated. We show that ring distorsions can be described using a geometrical potential term. We analyze the effect of this term on the current induced by a magnetic flux (persistent current) and by a polarized coherent electromagnetic field (radiation-induced current). The strongest effects in persistent currents are observed for distorted rings with a small number of electrons. The distortion smoothes the current oscillations as a function of the magnetic flux and changes the temperature dependence of the current amplitude. For radiation-induced currents, the distortion induces an ac component in …

Teaching Strategies In Mathematics: Differences In Sign Language Use, Heather A. Rowley

Theses

Problem: The proposed project addresses a critical problem facing most schools serving Deaf students in grades Kindergarten through college- insufficient clarity of sign communication by teachers due to wide variation in sign abilities. Today a very small number of teachers of the Deaf use American Sign Language in the classroom. Most teachers use other variations of sign language such as (1) Pidgin Signed English, (2) Signed English, (3) Simultaneous Communication, (4) Total Communication. Clear and effective communication is critically important to both students' learning in school and their success in future careers. Proposed Project Activities: This project will develop and …
