Televising The Court: A Category Mistake (Symposium On Televising The Supreme Court), Christina B. Whitman

Articles

The idea of televising Supreme Court oral arguments is undeniably appealing. Consequently, it is not surprising that reporters and politicians have been pressuring the Court to take this step. The other branches have been media-friendly for years, and Supreme Court arguments are already open to the public. Why should those of us who neither reside in Washington, D.C. nor have the time to attend Court proceedings be asked to depend on reporters for descriptions of the event? Even lower courts permit cameras. There is an understandable hunger for anything that will help us understand these nine individuals who have so …

Sources Of Presidential Papers And Documents On The Web, Barbara H. Garavaglia

Articles

The President of the United States and his staff produce a large volume of documents and other materials. These documents fall into two major categories. The first category is comprised of archival presidential materials such as papers, documents, visual and audio records of the presidency, and the personal papers of the president, his family, associates, and friends. This category of presidential material is primarily of interest to historians, political scientists, and other scholars because it provides "a comprehensive view of our Presidents and... [U.S.] history."1 The second category is comprised of presidential documents with legal effect used by the president …

Regulatory Beneficiaries And Informal Agency Policymaking, Nina A. Mendelson

Articles

Administrative agencies frequently use guidance documents to set policy broadly and prospectively in areas ranging from Department of Education Title IX enforcement to Food and Drug Administration regulation of direct-to-consumer pharmaceutical advertising. In form, these guidances often closely resemble the policies agencies issue in ordinary notice-and-comment rulemaking. However, guidances are generally developed with little public participation and are often immune from judicial review. Nonetheless, guidances can prompt significant changes in behavior from those the agencies regulate. A number of commentators have guardedly defended the current state of affairs. Though guidances lack some important procedural safeguards, they can help agencies supervise …

Creative Reading, Jessica D. Litman

Articles

Let me begin with something that Jamie Boyle wrote ten years ago in Intellectual Property Policy Online: A Young Person's Guide:' Copyright marks the attempt to achieve for texts and other works a balance in which the assumption of the system is that widespread use is possible without copying. The relative bundles of rights of the user and the owner achieve their balance based on a set of economic and technical assumptions about the meaning of normal use. For our purposes, I would like to generalize this as something that Boyle might have written if he had not in that …

On The Fortieth Anniversary Of The Miranda Case: Why We Needed It, How We Got It--And What Happened To It, Yale Kamisar

Articles

Last year (the year I gave the talk on which this article is based) marked the fortieth anniversary of Miranda v. Arizona,' one of the most praised, most maligned-and probably one of the most misunderstood-Supreme Court cases in American history. It is difficult, if not impossible, to evaluate Miranda without looking back at the test for the admissibility of confessions that preceded it.

Wireless Video Telephony Performance Enhancements: Towards Applied Network Engineering Approach, Justin Madigan, Fei Hu

Articles

The aim of this network engineering research is to improve video transmission performance (such as end-to-end delay) in video telephony applications in cellular network scenarios. There exists a definite need for quality-of-service (QoS) and guaranteed throughput when using streaming media. However, in wireless environments where resources are precious, this is often not possible, especially with a large user base that is communicating simultaneously. Not only does traffic load pose a problem, but also the inherent instability of the radio links makes the task considerably more difficult. This presents the need for a new method for undertaking the task of wireless …

Application Of Soft Computing Techniques To Estimate The Effective Young's Modulus Of Thin Film Materials, Ajay Pasupuleti, Ferat Sahin

Articles

This research aims at characterizing and predicting the Young’s Modulus of thin film materials that are utilized in Microelectromechanical systems (MEMS). Recent studies indicate that the mechanical properties such as Young’s Modulus of thin films are significantly different from the bulk values. Due to the lack of proper understanding of the physics in the micro-scale domain the state-of-art estimation techniques are unreliable and often unfit for use for predicating the mechanical behavior of slight modifications of existing designs as well as new designs. This disadvantage limits the MEMS designers to physical prototyping which is cost ineffective and time consuming. As …

Decision Theoretic Agent Design For Personal Rapid Transit Systems, Iheanyi Umez-Eronini, Ferat Sahin

Articles

This paper details a learning decision-theoretic intelligent agent designed to solve the problem of guiding vehicles in the context of Personal Rapid Transit (PRT). The intelligent agents are designed using Bayesian Decision Networks. The agents are designed to utilize the known methods of machine learning with Bayesian Networks (BN): parameter learning and structure learning. In addition, a new method of machine learning with BNs, termed utility learning in this paper, is introduced. BN software for Matlab is used to realize the proposed agent. Additional software is written to simulate the PRT problem using various intelligent agents that utilize one or …

The Acs Virgo Cluster Survey Xii: The Luminosity Function Of Globular Clusters In Early Type Galaxies, Andrés Jordán, Dean Mclaughlin, Patrick Côté, Laura Ferrarese, Eric W. Peng, Simona Mei, Daniela Villegas, David Merritt, John L. Tonry, Michael J. West

Articles

We analyze the luminosity function of the globular clusters (GCs) belonging to the early-type galaxies observed in the ACS Virgo Cluster Survey. We have obtained maximum likelihood estimates for a Gaussian representation of the globular cluster luminosity function (GCLF) for 89 galaxies. We have also fit the luminosity functions with an “evolved Schechter function”, which is meant to reflect the preferential depletion of low-mass GCs, primarily by evaporation due to two-body relaxation, from an initial Schechter mass function similar to that of young massive clusters in local starbursts and mergers. We find a highly significant trend of the GCLF dispersion …

More Complex Photogrammetry Projects, Andrew Davidhazy

Articles

Photography can be used for more than simply recording subjects and this article describes how it might be used in a science classroom as the basis for making measurements "on a shoestring". Added here in April 2007 although probably written in the early 1980s.

Making Orange Juice In A Flash, Andrew Davidhazy

Articles

A "vintage" article from June 2, 1980 in which a local newspaper (UPSTATE magazine) describes some high speed photography activities in A.Davidhazy's laboratory at RIT. Added here on a slow day in August 2007.

Basic Photogrammetry Techniques, Andrew Davidhazy

Articles

Before computers and photogrammetry related image processing programs much of the work of extracting information from aerial photographs was done by hand. Here are several very basic methods for finding out such things as the elevation above base of vertical objects, determining area of an irregular subject, determining area by graphical means and height of objects based on shadow. Added here in April 2007.

Multimodal Display Techniques With Application To Breast Imaging, Kimberly Rafferty, Karl Baum, Evan Schimdt, Andrzej Krol, Maria Helguera

Articles

Application of a multimodality approach is advantageous for detection, diagnosis and management of breast cancer. In this context, F-18-FDG positron emission tomography (PET), and high-resolution and dynamic contrast-enhanced magnetic resonance imaging (MRI) have steadily gained clinical acceptance. Obtaining the spatial relationships between these modalities and conveying them to the observer maximizes the benefit that can be achieved. Traditionally the registered images are displayed side by side. However, it is believed that a combined MRI/PET display may be more beneficial. The advantage of a combined image lies in our inability to visually judge spatial relationships between images when they are viewed …

Peroxisomes Contain A Specific Phytanoly-Coa/Pristanoyl-Coa Thioesterase Acting As A Novel Auxiliary Enzyme In Alpha-And Beta-Oxidation Of Methyl-Branched Fatty Acids In Mouse, Maria Westin, Mary Hunt, Stefan Alexson

Articles

Phytanic acid and pristanic acid are derived from phytol, which enter the body via the diet. Phytanic acid contains a methyl group in position three and therefore cannot undergo b-oxidation directly, but instead must first undergo a-oxidation to pristanic acid, which then enters b-oxidation. Both these pathways occur in peroxisomes, and in this study we have identified a novel peroxisomal acyl-CoA thioesterase, named ACOT6, which we show is specifically involved in phytanic acid and pristanic acid metabolism. Sequence analysis of ACOT6 revealed a putative peroxisomal targeting signal at the C-terminal end, and cellular localization experiments verified it as a peroxisomal …

Effects Of Mutations In The Helix G Region Of Horseradish Peroxidase, Barry Ryan, CiaráN Ó'FáGáIn

Articles

Horseradish Peroxidase (HRP) has long attracted intense research interest and is used in many biotechnological fields, including diagnostics, biosensors and biocatalysis. Enhancement of HRP catalytic activity and/or stability would further increase its usefulness. Based on prior art, we substituted solvent-exposed lysine and glutamic acid residues near the proximal helix G (Lys 232, 241; Glu 238, 239) and between helices F and F’ (Lys 174). Three single mutants (K232N, K232F, K241N) demonstrated increased stabilities against heat (up to two-fold) and solvents (up to four-fold). Stability gains are likely due to improved hydrogen bonding and space-fill characteristics introduced by the relevant substitution. …

Development And Assessment Of A Rapid Method To Detect Escherichia Coli O26, O111 And O157 In Retail Minced Beef., Mary Murphy, Anne Carroll, Paul Whyte, Micheál O'Mahoney, Wayne Anderson, Eleanor Mcnamara, Seamus Fanning, Ciara Walsh

Articles

A molecular-based detection method was developed to detect Escherichia coli O26, O111 and O157 in minced (ground) beef samples. This method consists of an initial overnight enrichment in modified tryptone soya broth (mTSB) and novobiocin prior to DNA extraction and subsequent serogrouping using a triplex PCR. This method has a low limit of detection and results are available within 24 hours of receipt of samples. Once optimized, this rapid method was utilized to determine the prevalence of these E. coli serogroups in six hundred minced beef samples all of which were previously examined by immunomagnetic separation (IMS) and selective plating …

Enterobacter Sakazakii: An Emerging Microbe With Implications For Infant Health, N. R. Mullane, B. Healy, Ciara Walsh, C. Iversen, P. Whyte, P. G. Wall, T. Quinn, Seamus Fanning

Articles

Enterobacter sakazakii (E. sakazakii) is an opportunistic pathogen and the aetiological agent in rare but life-threatening cases of meningitis, necrotizing enterocolitis, and sepsis in infants. Among infants, those at greatest risk are neonates (<28 >days), particularly those born prematurely or of low birth weight (g). Consumption of contaminated powdered infant formula (PIF) has been epidemiologically linked with cases of infection. Contamination can occur during the manufacturing process or during postmanufacture reconstitution of formula. Development of rapid, sensitive and specific detection methods will facilitate manufacturers efforts to reduce the occurrence of E. sakazakii in the final powdered product. Furthermore, since PIF …

A New Approach To The Toxicity Testing Of Carbon-Based Nanomaterials: The Clonogenic Assay, Eva Herzog, Alan Casey, Fiona Lyng, Gordon Chambers, Hugh Byrne, Maria Davoren

Articles

The cellular toxicity of three types of carbon nanoparticles, namely HiPco® single-walled carbon nanotubes (SWCNT), arc dischargeSWCNTand Printex 90 carbon black nanoparticles,was studied on three different cell models including the human alveolar carcinoma epithelial cell line (A549), the normal human bronchial epithelial cell line (BEAS-2B) and the human keratinocyte cell line (HaCaT) using the clonogenic assay. Carbon nanomaterials are known to interact with colorimetric indicator dyes frequently used in cytotoxicity assays. By employing the clonogenic assay, any such interactions could be avoided, allowing a more reliable method for the in vitro toxicity assessment of carbon-based nanoparticles. It could be shown …

Command Of The Commons Boasts: An Invitation To Lawfare?, Craig H. Allen

Articles

The first panel in this, the 2006 Naval War College, International Law Department conference on "Global Legal Challenges: Command of the Commons, Strategic Communications, and Natural Disasters," has been asked to offer a US perspective on current assertions regarding the US command of the commons. It is my privilege to moderate the discussion by a distinguished panel that includes Vice Admiral Lowell E. ("Jake") Jacoby, US Navy (retired) the immediate past director of the Defense Intelligence Agency; Vice Admiral John G. Morgan, Jr., US Navy, deputy chief of naval operations for plans and strategy (N3/N5); and Rear Admiral Joseph L. …

The Limits Of Intelligence In Maritime Counterproliferation Operations, Craig Allen

Articles

This article begins with an examination of the intelligence needs of those engaged in maritime counterproliferation efforts. It then turns to risk-management decision making under conditions of uncertainty, focusing on decisions at the operational level and exploring the question of whether decision strategies in the WMD context should seek to minimize false-negative or false-positive errors. It concludes that even vastly improved maritime intelligence will not obviate the need for national and operational commanders to make decisions under conditions of uncertainty and that such decisions should be made on the basis of established risk-assessment and management principles. At the same time, …

Public Interest Research, Collaboration, And The Promise Of Wikis, Tom Cobb

Articles

One of my central goals in teaching law is to help students find ways to apply their emerging analytical powers and professional skills to promote the public interest.A related goal is to create an engaging learning experience in which students see each other—and other members of the legal community—as key resources in their education.

To help accomplish these goals, I have been formally and informally collaborating with clinics—the traditional home of public interest law and collaborative learning in most law schools— to find ways to infuse my legal writing classes with clinical methods and values. This article describes a class …

Be Careful What You Ask For: Educacion Para Todas/Os, The Perils And The Power, Jessica Solyom, Jeremiah Chin, Kristi Ryujin

Articles

Demonstrations supporting human and civil rights, while often romanticized as a phenomenon of the past, are becoming more pervasive today, reflecting the continued forms of discrimination and oppression undocumented workers, individuals, and families experience. In the past few years, Utah residents have been engaged in their own battle to determine the level of support the state is willing to extend students of color interested in attending institutions of higher education. On the "frontstage" many of the state's universities echo a rhetoric of support for diversity. Some even go as far as to outline their commitment to diversity as part of …

Increased Mitochondrial Mass In Cells With Functionally Compromised Mitochondria After Exposure To Both Direct Y Radiation And Bystander Factors, Sharon Nugent, Carmel Mothersill, C. Seymour, B. Mcclean, Fiona Lyng, James Murphy

Articles

The bystander effect describes radiation-like damage in unirradiated cells either in the vicinity of irradiated cells or exposed to medium from irradiated cells. This study aimed to further characterize the poorly understood mitochondrial response to both direct irradiation and bystander factor(s) in human keratinocytes (HPV-G) and Chinese hamster ovarian cells (CHO-K1). Oxygen consumption rates were determined during periods of state 4, state 3 and uncoupled respiration. Mitochondrial mass was determined using MitoTracker FM. CHO-K1 cells showed significantly reduced oxygen consumption rates 4 h after exposure to 5 Gy direct radiation and irradiated cell conditioned medium (ICCM) and an apparent recovery …

Digital Watermarking And Self-Authentication Using Chirp Coding, Jonathan Blackledge

Articles

This paper discusses a new approach to ‘watermarking’ digital signals using linear frequency modulated or ‘chirp’ coding. The principles underlying this approach are based on the use of a matched filter to provide a reconstruction of a chirped code that is uniquely robust, i.e. in the case of very low signal-to-noise ratios.

Chirp coding for authenticating data is generic in the sense that it can be used for a range of data types and applications (the authentication of speech and audio signals, for example). The theoretical and computational aspects of the matched filter and the properties of a chirp are …

Quantum Dot Energy Relaxation Mediated By Plasmon Emission In Doped Covalent Semiconductor Heterostructures, A. V. Fedorov, Anna Baranov, I. D. Rukhlenko, T. S. Perova, Kevin Berwick

Articles

The interaction between interface plasmons within a doped substrate and quantum dot electrons or holes has been theoretically studied in double heterostructures based on covalent semiconductors. The interface plasmon modes, the corresponding dispersion relationship, and the intraband carrier relaxation rate in quantum dots are reported. We find the critical points in the interface plasmon density of states for multilayered structures results in enhanced quantum dot intraband carrier relaxation when compared to that for a single heterostructure. A detailed discussion is made of the relaxation rate and the spectral position dependencies on the quantum dot layer thickness as well as on …

Diffusion And Fractional Diffusion Based Models For Multiple Light Scattering And Image Analysis, Jonathan Blackledge

Articles

This paper considers a fractional light diffusion model as an approach to characterizing the case when intermediate scattering processes are present, i.e. the scattering regime is neither strong nor weak. In order to introduce the basis for this approach, we revisit the elements of formal scattering theory and the classical diffusion problem in terms of solutions to the inhomogeneous wave and diffusion equations respectively. We then address the significance of these equations in terms of a random walk model for multiple scattering. This leads to the proposition of a fractional diffusion equation for modelling intermediate strength scattering that is based …
