Casimir Interactions Of An Object Inside A Spherical Metal Shell, Saad Zaheer, Sahand Jamal Rahi, Thorsten Emig, Robert L. Jaffe 2010 University of Pennsylvania

Casimir Interactions Of An Object Inside A Spherical Metal Shell, Saad Zaheer, Sahand Jamal Rahi, Thorsten Emig, Robert L. Jaffe

Department of Physics Papers

We investigate the electromagnetic Casimir interactions of an object contained within an otherwise empty, perfectly conducting spherical shell. For a small object we present analytical calculations of the force, which is directed away from the center of the cavity, and the torque, which tends to align the object opposite to the preferred alignment outside the cavity. For a perfectly conducting sphere as the interior object, we compute the corrections to the proximity force approximation (PFA) numerically. In both cases the results for the interior configuration match smoothly onto those for the corresponding exterior configuration.

BACKGROUND: The UVB component of solar ultraviolet irradiation is one of the major risk factors for the development of skin cancer in humans. UVB exposure elicits an increased generation of reactive oxygen species (ROS), which are responsible for oxidative damage to proteins, DNA, RNA and lipids. In order to examine the biological impact of UVB irradiation on skin cells, we used a parallel proteomics approach to analyze the protein expression profile and to identify oxidatively modified proteins in normal human epithelial keratinocytes.

RESULTS: The expression levels of fifteen proteins - involved in maintaining the cytoskeleton integrity, removal of damaged proteins and ...

DePauw University is a small, liberal arts institution with 2200 undergraduate residential students and 222 faculty members, located in Greencastle, Indiana The challenges of supporting a campus with multiple and diverse facilities are further amplified by limited staff support resources. One of the strategies for addressing these challenges led to the formation of the Computing Labs and Technology Classrooms (CLTC) initiative. The CLTC recognizes and draws on the strengths of support specialists with a wide variety of professional training and experience, who regularly collaborate in the support and management of campus-wide labs and technology classrooms.


Statistical Mechanics Of Splay Flexoelectricity In Nematic Liquid Crystals, Subas Dhakal, Jonathan Selinger 2010 Kent State University - Kent Campus

Statistical Mechanics Of Splay Flexoelectricity In Nematic Liquid Crystals, Subas Dhakal, Jonathan Selinger

Chemical Physics Publications

We develop a lattice model for the splay flexoelectric effect in nematic liquid crystals. In this model, each lattice site has a spin representing the local molecular orientation, and the interaction between neighboring spins represents pear-shaped molecules with shape polarity. We perform Monte Carlo simulations and mean-field calculations to find the behavior as a function of interaction parameters, temperature, and applied electric field. The resulting phase diagram has three phases: isotropic, nematic, and polar. In the nematic phase, there is a large splay flexoelectric effect, which diverges as the system approaches the transition to the polar phase. These results show ...

High-Spatial And High-Mass Resolution Imaging Of Surface Metabolites Of Arabidopsis Thaliana By Laser Desorption-Ionization Mass Spectrometry Using Colloidal Silver, Ji Hyun Jun, Zhihong Song, Zhenjiu Liu, Basil Nikolau, Edward S. Yeung, Young Jin Lee

Chemistry Publications

High-spatial resolution and high-mass resolution techniques are developed and adopted for the mass spectrometric imaging of epicuticular lipids on the surface of Arabidopsis thaliana. Single cell level spatial resolution of ∼12 μm was achieved by reducing the laser beam size by using an optical fiber with 25 μm core diameter in a vacuum matrix-assisted laser desorption ionization-linear ion trap (vMALDI-LTQ) mass spectrometer and improved matrix application using an oscillating capillary nebulizer. Fine chemical images of a whole flower were visualized in this high spatial resolution showing substructure of an anther and single pollen grains at the stigma and anthers. The ...


Paleointensity Estimates From Ignimbrites: An Evaluation Of The Bishop Tuff, Jeffrey S. Gee, Yongjae Yu, Julie A. Bowles 2010 University of California - San Diego

Paleointensity Estimates From Ignimbrites: An Evaluation Of The Bishop Tuff, Jeffrey S. Gee, Yongjae Yu, Julie A. Bowles

Geosciences Faculty Articles

Ash flow tuffs, or ignimbrites, typically contain fine-grained magnetite, spanning the superparamagnetic to single-domain size range that should be suitable for estimating geomagnetic field intensity. However, ignimbrites may have a remanence of thermal and chemical origin as a result of the complex magnetic mineralogy and variations in the thermal and alteration history. We examined three stratigraphic sections through the ~0.76 Ma Bishop Tuff, where independent information on postemplacement cooling and alteration is available, as a test of the suitability of ignimbrites for paleointensity studies. Thermomagnetic curves suggest that low-Ti titanomagnetite (Tc = 560°C–580°C) is the dominant ...


Rapid Hydrologic Shifts And Prolonged Droughts In Rocky Mountain Headwaters During The Holocene, Bryan Shuman, P. Pribyl, T. A. Minckley, J. J. Shinker 2010 University of Wyoming

Rapid Hydrologic Shifts And Prolonged Droughts In Rocky Mountain Headwaters During The Holocene, Bryan Shuman, P. Pribyl, T. A. Minckley, J. J. Shinker

Geology and Geophysics Faculty Publications

Rapid hydroclimatic shifts repeatedly generated centuries to millennia of extensive aridity across the headwaters of three of North America's largest river systems during the Holocene. Evidence of past lake-level changes at the headwaters of the Snake-Columbia, Missouri-Mississippi, and Green-Colorado Rivers in the Rocky Mountains shows that aridity as extensive and likely as severe as the CE 1930s Dust Bowl developed within centuries or less at ca. 9 ka (thousand years before CE 1950), and persisted across large areas of the watersheds until ca. 3 ka. Regional water levels also shifted abruptly at >11.3 and 1.8-1.2 ka ...


Radiation Emission From Wrinkled Sige/Sige Nanostructure, A. I. Fedorchenko, H. H. Cheng, Greg Sun, R. A. Soref 2010 Institute of Thermomechanics, Academy of Sciences of the Czech Republic

Radiation Emission From Wrinkled Sige/Sige Nanostructure, A. I. Fedorchenko, H. H. Cheng, Greg Sun, R. A. Soref

Physics Faculty Publications

Semiconductor optical emitters radiate light via band-to-band optical transitions. Here, a different mechanism of radiation emission, which is not related to the energy band of the materials, is proposed. In the case of carriers traveling along a sinusoidal trajectory through a wrinkled nanostructure, radiation was emitted via changes in their velocity in a manner analogous to synchrotron radiation. The radiated frequency of wrinkled SiGe/SiGe nanostructure was found to cover a wide spectrum with radiation power levels of the order of submilliwatts. Thus, this nanostructure can be used as a Si-based optical emitter and it will enable the integration of ...


Panel Count Data Regression With Informative Observation Times, Petra Buzkova 2010 University of Washington

Panel Count Data Regression With Informative Observation Times, Petra Buzkova

UW Biostatistics Working Paper Series

When patients are monitored for potentially recurrent events such as infections or tumor metastases, it is common for clinicians to ask patients to come back sooner for follow-up based on the results of the most recent exam. This means that subjects’ observation times will be irregular and related to subject-specific factors. Previously proposed methods for handling such panel count data assume that the dependence between the events process and the observation time process is time-invariant. This article considers situations where the observation times are predicted by time-varying factors, such as the outcome observed at the last visit or cumulative exposure ...


Normal And Reverse Faulting Driven By The Subduction Zone Earthquake Cycle In The Northern Chilean Forearc, John P. Loveless, Richard W. Allmendinger, Matthew E. Pritchard, Gabriel González 2010 Smith College

Normal And Reverse Faulting Driven By The Subduction Zone Earthquake Cycle In The Northern Chilean Forearc, John P. Loveless, Richard W. Allmendinger, Matthew E. Pritchard, Gabriel González

Geosciences: Faculty Publications

Despite its location in a convergent tectonic setting, the Coastal Cordillera of northern Chile between 21°S and 25°S is dominated by structures demonstrating extension in the direction of plate convergence. In some locations, however, normal faults have been reactivated as reverse faults, complicating the interpretation of long-term strain. In order to place these new observations in a tectonic context, we model stress changes induced on these faults by the subduction earthquake cycle. Our simulations predict that interseismic locking on the plate boundary encourages normal slip on fore-arc faults, which may result from elastic rebound due to interplate earthquakes ...


The Use Of Olap Reporting Technology To Improve Patient Care Services Decision Making Within The University Health Center, Carlos M. Gonzalez 2010 Regis University

The Use Of Olap Reporting Technology To Improve Patient Care Services Decision Making Within The University Health Center, Carlos M. Gonzalez

All Regis University Theses

The purpose of this paper is to demonstrate that it is feasible for the student health center to leverage existing clinical data in a data warehouse by using OLAP reporting in order to improve patient care and health care services decision making. Historically, University health care centers have relied mainly on operational data sources for critical health care decision making. These sources of data do not contain enough information to allow health officials to recognize trends or predict how future changes in health care services might vastly improve overall heath care. Four proof of concept artifacts are constructed through design ...


Mapping System Management Of Two Erps (Oracle Ebusiness Suit And Peoplesoft), Eric Hernandez 2010 Regis University

Mapping System Management Of Two Erps (Oracle Ebusiness Suit And Peoplesoft), Eric Hernandez

All Regis University Theses

Due to the fact that Enterprise Resource Planning (ERP) vendors provide business solutions to address similar business challenges, most ERP products have a lot of similar components and functionalities. Using these similar components and functionalities, ERP system management of one ERP product can be mapped to a different ERP product. In this particular case, E-Business Suite's (EBS) system management is mapped against PeopleSoft (PS). By having an EBS Administrator indirectly collaborate with a PS administrator, a system management mapping table linking the two ERP systems was established. By allowing an EBS Administrator handle PS systems using the mapping solution ...


Data Summary From The Tampa Bay Interagency Seagrass Monitoring Program Through Year 2008, Walt Avery, Roger Johansson 2010 University of South Florida

Data Summary From The Tampa Bay Interagency Seagrass Monitoring Program Through Year 2008, Walt Avery, Roger Johansson

Reports

In 1997, the TBEP coordinated the creation of a bay-wide fixed transect seagrass monitoring program. The primary goal of the program is to document temporal and spatial changes in seagrass species composition, abundance, and distribution along a depth gradient. Several bay area agencies committed personnel and equipment to the program. Data collection from 60 transects began in 1998. Currently, 62 transects are monitored due to revisions in transect selection and location. This paper presents a general summary of Tampa Bay seagrass trends from 1998-2008


Determination Of Energy Level Excitation States Of Time Dependent Optogalvanic Signals In A Discharge Plasma, Michael Christopher Blosser 2010 Butler University

Determination Of Energy Level Excitation States Of Time Dependent Optogalvanic Signals In A Discharge Plasma, Michael Christopher Blosser

Undergraduate Honors Thesis Collection

When tuning a laser between two excited energy levels of the atoms in a discharge plasma, the discharge current will temporarily be disturbed. This disturbance or change in current is the optogalvanic effect (OGE). The fundamental goal of this project is to determine the exponential rates in the time-dependent OGE signals. These rates are related to the collision rates for the atoms in the plasma. The OGE data will be experimentally recorded, fitted, and analyzed to extract the exponential rates related to the energy levels of the atom in gas in the discharge lamp.


Extensions Of Nearest Shrunken Centroid Method For Classification, Tomohiko Funai 2010 Brigham Young University - Provo

Extensions Of Nearest Shrunken Centroid Method For Classification, Tomohiko Funai

All Theses and Dissertations

Stylometry assumes that the essence of the individual style of an author can be captured using a number of quantitative criteria, such as the relative frequencies of noncontextual words (e.g., or, the, and, etc.). Several statistical methodologies have been developed for authorship analysis. Jockers et al. (2009) utilize Nearest Shrunken Centroid (NSC) classification, a promising classification methodology in DNA microarray analysis for authorship analysis of the Book of Mormon. Schaalje et al. (2010) develop an extended NSC classification to remedy the problem of a missing author. Dabney (2005) and Koppel et al. (2009) suggest other modifications of NSC. This ...
