Secure Communications With An Asymptotic Secrecy Model, Bo Yuan

Articles

As knowledge based systems become more sophisticated, communications between systems or among their subsystems often conducted over public channels such as the Internet, wireless medium, etc. To secure communications over public channels, the most often used method is Diffie and Hellman’s public key infrastructure approach. This method requires a trusted third party to verify identifies, which does not play well with independent knowledge based systems, especially in the case of autonomous agents. In this paper, we proposes an asymptotic secrecy model to secure communications between and within knowledge based systems over public channels. The new model assumes that adversaries are …

Optimal Tax Compliance And Penalties When The Law Is Uncertain, Kyle D. Logue

Articles

This article examines the optimal level of tax compliance and the optimal penalty for noncompliance in circumstances in which the substance of the tax law is uncertain - that is, when the precise application of the Internal Revenue Code to a particular situation is not clear. In such situations, a number of interesting questions arise. This article will consider two of them. First, as a normative matter, how certain should taxpayers be before they rely on a particular interpretation of a substantively uncertain tax rule? If a particular position is not clearly prohibited but neither is it clearly allowed, what …

The Wait Is Over: Chevron As The Stealth Vermont Yankee Ii, Paul R. Verkuil

Articles

The article argues that the Chevron doctrine has effectively served as a means to moderate the hard-look review of agency rulemaking, rendering the anticipated Vermont Yankee II case unnecessary. It posits that Chevron's deference to agency interpretations of statutes has softened the impact of State Farm's stringent arbitrary-and-capricious review standard, aligning more closely with the judicial restraint envisioned by Vermont Yankee.

An Investigation Of Introductory Physics Students’ Approaches To Problem Solving, Laura Walsh, Robert Howard, Brian Bowe

Articles

This paper outlines ongoing research investigating students’ approaches to quantitative and qualitative problem solving in physics. This is an empirical study, which was conducted using a phenomenographic approach to analyse and interpret data from individual semi-structured interviews with students from introductory physics courses. The result of the study thus far is a preliminary set of hierarchical categories that describe the students’ problem-solving approaches when faced with various physics problems. The findings from the research presented here indicate that many introductory students in higher education do not approach problem solving in a strategic manner and many do not try to link …

Evaluation Of The Idi-Mrsa Assay On The Smartcycler Real-Time Pcr Platform For Rapid Detection Of Mrsa From Screening Specimens, Celine Herra, A. S. Rossney, M. Fitzgibbon, P. Morgan, B. O’Connell

Articles

Rapid accurate detection is a prerequisite for the successful control of meticillin-resistant Staphylococcus aureus (MRSA). The IDI-MRSA real-time polymerase chain reaction (PCR) assay was designed to provide rapid results from nasal specimens collected in Stuart’s liquid transport medium. This study has evaluated the IDI-MRSA kit for use in a clinical laboratory by investigating the following parameters: (1) limits of detection (LoD), (2) performance with Amies’ gel-based transport medium, (3) ability to detect strains of MRSA in a collection representative of MRSA in Ireland since 1974 (n 113) and (4) performance in a clinical trial with swabs from nose, throat and …

Comparisons Of Binary Black Hole Merger Waveforms, John Baker, Manuela Campanelli, Frans Pretorius, Yosef Zlochower

Articles

This a particularly exciting time for gravitational wave physics. Ground-based gravitational wave detectors are now operating at a sensitivity such that gravitational radiation may soon be directly detected, and recently several groups have independently made significant breakthroughs that have finally enabled numerical relativists to solve the Einstein field equations for coalescing black-hole binaries, a key source of gravitational radiation. The numerical relativity community is now in the position to begin providing simulated merger waveforms for use by the data analysis community, and it is therefore very important that we provide ways to validate the results produced by various numerical approaches. …

Automated Extraction Of Fire Line Parameters From Multispectral Infrared Images, Ambrose Ononye, Anthony Vodacek, Eli Saber

Articles

Remotely sensed infrared images are often used to assess wildland ¯re conditions. Separately, ¯re propagation models are in use to forecast future conditions. In the Dynamic Data Driven Application System (DDDAS) concept, the ¯re propagation model will react to the image data, which should produce more accurate predictions of ¯re propagation. In this study we describe a series of image processing tools that can be used to extract ¯re propagation parameters from multispectral infrared images so that the parameters can be used to drive a ¯re propagation model built upon the DDDAS concept. The method is capable of automatically determining …

Suction Feeding Mechanics, Performance, And Diversity In Fishes, Peter Wainwright, Andrew Carroll, David Collar

Articles

Despite almost 50 years of research on the functional morphology and biomechanics of suction feeding, no consensus has emerged on how to characterize suction-feeding performance, or its morphological basis. We argue that this lack of unity in the literature is due to an unusually indirect and complex linkage between the muscle contractions that power suction feeding, the skeletal movements that underlie buccal expansion, the sharp drop in buccal suction pressure that occurs during expansion, the flow of water that enters the mouth to eliminate the pressure gradient, and the forces that are ultimately exerted on the prey by this flow. …

Model Atmospheres For Irradiated Giant Stars: Implications For The Galactic Center, Raul Jiminez, Juliana Silva, S. Peng Oh, Uffe G. Jørgensen, David Merritt

Articles

Irradiation of a stellar atmosphere by an external source (e.g. an AGN) changes its structure and therefore its spectrum. Using a state-of-the-art stellar atmosphere code, we calculate the infrared spectra of such irradiated and transformed stars. We show that the original spectrum of the star, which is dominated by molecular bands, changes dramatically when irradiated even by a low-luminosity AGN (LX = 1033 erg s−1), becoming dominated by atomic lines in absorption. We study the changes in the spectrum of low-mass carbon- and oxygen-rich giant stars as they are irradiated by a modest AGN, similar to the one at the …

Probability Thresholds, Jonathan Masur

Articles

Scholars and lower courts have traditionally operated under the belief that cases involving direct tradeoffs between free speech and national security call for the application of straightforward cost-benefit analysis. But the Supreme Court has refused to adhere to this approach, instead deciding difficult liberty-versus-security questions with reference to a "probability threshold"--a doctrinal floor defining how likely a potential threat must be in order to register in the constitutional calculus. This doctrinal innovation has served as a necessary corrective to what would otherwise be the systematic overestimation of speech-based threats driven by the interaction of two factors. First, distinct informational asymmetries …

Effect Of Snr Of Input Signal On The Accuracy Of A Ratiometric Wavelength Measurement System, Ginu Rajan, Qian Wang, Gerald Farrell, Yuliya Semenova, Pengfei Wang

Articles

The impact of a change in SNR of the input signal on the accuracy of a ratiometric wavelength measurement system is studied. The variation of the output ratio of the system due to the change in SNR of the input signal is modeled and the experimental investigation has been carried out, and both indicate that the accuracy is influenced significantly by variations in the SNR of the input signal. The demonstration example shows a wavelength shift of 0.055 nm when the SNR of the input signal varies from 47 dB to 42 dB (the measurable range is from 1500 nm …

Using The Technology Of The Confessional As An Analytical Resource: Four Analytical Stances Towards Research Interviews In Discourse Analysis, Brendan O'Rourke, Martyn Pitt

Articles

Among the various approaches that have developed from FOUCAULT's work is an Anglophone discourse analysis that has attempted to combine FOUCAULTian insights with the techniques of Conversation Analysis. An important current methodological issue in this discourse analytical approach is its theoretical preference for "naturally occurring" rather than research interview data. A FOUCAULTian perspective on the interview as a research instrument, questions the idea of "naturally-occurring discourse". The "technology of the confessional" operates, not only within research interviews, but permeates other interactions as well. Drawing on FOUCAULT does not dismiss the problems of the interview as research instrument rather it shows …

The Acyl-Coa Thioesterase I (Acot1) Is Regulated By The Peroxisome Proliferator-Activated Receptor Alpha And Hepatocyte Nuclear Factor 4 Alpha Via A Distal Response Element In The Promotor., Bikesh Dongol, Yatrik Shah, Insook Kim, Frank J. Gonzalez, Mary Hunt

Articles

The cytosolic acyl-CoA thioesterase I (Acot1) is an enzyme that hydrolyzes longchain acyl-CoAs of C12-C20-CoA in chain-length, to the free fatty acid and coenzyme A. Acot1 was previously shown to be strongly upregulated at mRNA and protein level in rodents by fibrates. In this study, we show that Acot1 mRNA levels were increased 90-fold in liver by treatment with Wy-14,643 and that Acot1 mRNA is also increased 15-fold in the liver of hepatocyte nuclear factor 4 alpha (HNF4a) knockout animals. Our study identified a direct repeat 1 (DR1) located in the Acot1 gene promotor in mouse, which binds the peroxisome …

The Heating Mechanism For The Warm/Cool Dust In Powerful, Radio-Loud Active Galactic Nuclei, Clive Tadhunter, D. Dicken, J. Holt, K. Inskip, R. Morganti, David J. Axon, C. Buchanan, R. González Delgado, P. Barthel, I. Van Bemmel

Articles

The uncertainty surrounding the nature of the heating mechanism for the dust that emits at mid- to far-IR (MFIR) wavelengths in active galaxies limits our understanding of the links between active galactic nuclei (AGN) and galaxy evolution, as well as our ability to interpret the prodigious infrared and submm emission of some of the most distant galaxies in the Universe. Here we report deep Spitzer observations of a complete sample of powerful, intermediate redshift (0.05 < z < 0.7) radio galaxies and quasars. We show that AGN power, as traced by [OIII] 5007 emission, is strongly correlated with both the mid-IR (24μm) and the far-IR (70μm) luminosities, however, with increased scatter in the 70μm correlation. A major cause of this increased scatter is a group of objects that falls above the main correlation and displays evidence for prodigious recent star formation activity at optical wavelengths, along with relatively cool MFIR colours. These results provide evidence that illumination by the AGN is the primary heating mechanism for the dust emitting at both 24 and 70μm, with starbursts dominating the heating of the cool dust in only 20 – 30% of objects. This implies that powerful AGN are not always accompanied by the type of luminous starbursts that are characteristic of the peak of activity in major gas-rich mergers.

Performing Tourism In Venice: Local Residents In Focus, Bernadette Quinn

Articles

In contrast to the growing literature on tourist mobility as a performed art, relatively little attention has been paid to resident mobility in tourism places. This paper examines how residents encounter tourists using the concept of tourism as a performance. Drawing on the case of the historic city-center of Venice in northeastern Italy, it explores the spatialities produced through the embodied practices of local mobilities. The paper finds that their movements demonstrated a marked degree of agency. It concludes by arguing that the concept of tourism as performance affords useful insights into how local residents are proactively and intricately involved …

Polarization Dependence Of Bend Loss For A Standard Singlemode Fiber, Qian Wang, Ginu Rajan, Pengfei Wang, Gerald Farrell

Articles

Polarization dependence of bend loss caused by the polymer coating layer for a standard singlemode fiber (SMF28) is investigated theoretically and experimentally. Bend loss for SMF28 for both the TE and TM mode is calculated separately. Normalized polarization dependent loss is proposed for the characterization of the polarization sensitivity of bend loss for different bend radii. Corresponding experimental tests are presented, which agree with the theoretical results. Both the theoretical and experimental results show that the polymer coating layer has a significant influence on the polarization dependence of bend loss.

Mapping The Literature Of Health Care Management, Mary K. Taylor, Meseret D. Gebremichael, Cassie Wagner

Articles

Objectives: The research provides an overview of the health care management literature and the indexing coverage of core journal literature.

Method: Citations from five source journals for the years 2002 through 2004 were studied using the protocols of the Mapping the Literature of Allied Health Project and Mapping the Literature of Nursing Project. The productivity of cited journals was analyzed by applying Bradford's Law of Scattering.

Results: Journals were the most frequently cited format, followed by books. Only 3.2% of the cited journal titles from all 5 source journals generated two-thirds of the cited titles. When only the health care …

A Three‐Dimensional Numerical Method For Modelling Weakly Ionized Plasmas, Stephen O'Sullivan, Turlough Downes

Articles

Astrophysical fluids under the influence of magnetic fields are often subjected to single- or two-fluid approximations. In the case of weakly ionized plasmas, however, this can be inappropriate due to distinct responses from the multiple constituent species to both collisional and non-collisional forces. As a result, in dense molecular clouds and protostellar accretion discs, for instance, the conductivity of the plasma may be highly anisotropic leading to phenomena such as Hall and ambipolar diffusion strongly influencing the dynamics.

The Internationalization Of Lay Legal Decision-Making: Jury Resurgence And Jury Research, Richard O. Lempert

Articles

When I first began to study the jury more than thirty years ago, the topic of this Journal issue, jury systems around the world, was unthinkable. The use of juries, especially in civil litigation, had long been in decline, to the point of near extinction in England, the land of their birth, and the live question was whether the jury system would endure in the United States. It seemed clear that juries would not continue in their classic form, as many U.S. states, with the Supreme Court's eventual approval, mandated juries of less than twelve people and allowed verdicts to …
