Nitric Oxide Mediates Seasonal Muscle Potentiation In Clam Gills, Louis F. Gainey Jr., Michael J. Greenberg

Faculty Publications

The physiology and timing of gill muscle potentiation were explored in the clam Mercenaria mercenaria. When isolated demibranchs were exposed twice (with an intervening wash) to the same concentration of 5-hydroxytryptamine, the second contraction was larger than the first. This potentiation was seasonal: it was present from November through June, and absent from July through October. Potentiation was not affected by the geographic origin of the clams, nor by their acclimation temperature. Potentiation was inhibited by the nitric oxide synthase (NOS) inhibitor L-NAME and mimicked by the nitric oxide (NO) donor DEANO. During the season of potentiation, immunoreactive NOS appeared …

Ten Things Deans Can Do With Students, R. Lawrence Dessem

Faculty Publications

A healthy relationship with students is beneficial to one's deanship, law school, and to the dean herself. An experienced provost once told me that serving as dean was the best job that he had ever had because he still had significant contact with students. Deans should take advantage of the possibilities for student interactions that their deanships afford them. What follows is my “top ten list” of ways in which deans can build a positive relationship with their students.

Follow The Worker, Not The Work: Hard Lessons From Failed London Music Hall Magazines, Scott B. Fosdick

Faculty Publications

London’s music hall stages and the variety entertainment that flourished there at the turn of the 20th century gave rise to a raft of magazines hopeful of gaining an audience from fans and/or performers and theater managers. Some flourished for a time, but all died with the artform, unlike their American cousin, Variety, which still thrives nearly a century after its first issue. This article compares the founding missions of these magazines to that of Variety in search of guiding principles for magazine management, particularly of business publications, in industries undergoing rapid change. The conflict between two long-standing principles of …

Toward Common Content: An Analysis Of Online College And University Collecting Policies, Jennifer A. Marshall

Faculty Publications

Collecting policies have been advocated as tools to help archivists build stronger collections. The model proposed by Faye Phillips in 1984 is the most detailed framework for collecting policies in the archival literature. This paper presents the results of a pilot study of the collecting policies of college and university archives available online to investigate whether a consensus has been reached about the content of these documents. Future studies of this kind for other types of archives could facilitate the identification, refinement, and dissemination of professional best practice and standards for collecting policies.

Long Memory Inflationary Dynamics: The Case Of Brazil, Mark E. Jensen, Valderio A. Reisen, Francisco Cribari-Neto

Faculty Publications

It has been argued by several authors that the inflationary dynamics in Brazil follow a unit root process, thus displaying some inertia. Indeed, Cati, et al. (Journal of Applied Econometrics, 1999) have found that the inflationary dynamics in Brazil are nearly fully inertial. We estimate the fractional differencing parameter using an ARFIMA specification for the inflation rate in that country and our results suggest that the inflationary dynamics are better modeled by a long memory process than by a unit root mechanism, thus implying that there is no inertia in inflation, contrary to what has been found by other researchers. …

Quantum Noise In Gravitational-Wave Interferometers: Overview And Recent Developments, Thomas Corbitt, Nergis Mavalvala

Faculty Publications

We present an overview of quantum noise in gravitational wave interferometers. Gravitational wave detectors are extensively modified variants of a Michelson interferometer and the quantum noise couplings are strongly influenced by the interferometer configuration. We describe recent developments in the treatment of quantum noise in the complex interferometer configurations of present-day and future gravitational-wave detectors. In addition, we explore prospects for the use of squeezed light in future interferometers, including consideration of the effects of losses, and the choice of optimal readout schemes.

Trust Negotiation For Authentication And Authorization In Healthcare Information Systems, Charles D. Knutson, Kent E. Seamons, Tore L. Sundelin, David K. Vawdrey

Faculty Publications

The expanding availability of health information in an electronic format is strategic for industry-wide efforts to improve the quality and reduce the cnst of health care. The implementation of electronic medical record systems has been hindered by inadequate security provisions. This paper describes the use of frust negotiation as a framework for providing authentication and access control services in healthcare information systems. nust negotiation enables two parties with no pre-existing relationship to establish the trust necessary to perform sensitive transactions via the mutual disclosure of attributes contained within digital credentials. An extension of this system, surrogate irusf negoikiion is introduced …

Evaluating Tmr Techniques In The Presence Of Single Event Upsets, Paul S. Graham, Nathaniel Rollins, Michael J. Wirthlin, Michael P. Caffrey

Faculty Publications

Sponsorship: Los Alamos National Labs (LA-UR-03-7525). Field programmable gate arrays (FPGAs) are sensitive to radiation-induced single event upsets (SEUs) within the configuration memory. Triple modular redundancy (TMR) is a technique commonly used to mitigate against design failures caused by SEUs. This paper evaluates the effectiveness and cost of TMR on two different counter designs in the presence of SEUs. The evaluation measures the reliability, area cost, and speed of different TMR styles. The tests show that when feedback TMR is used with triplicated clocks, it is possible to have counter design which is insensitive to any single configuration upset.

Can Joy And Reverence Coexist? A Look At Worship And Culture, Lilianne Douhkan

Faculty Publications

"What is the right form of worship? Is there only one correct form or style of worship? Have worship forms changed over time? Who is to decide which form or format is appropriate for worship? Almost everyone involved in the organization of worship has been confronted with such questions.

"Within the ensuing discussions there is an abundance of good intent, but also a plethora of personal opinions, and very often little understanding of what worship really is. I would like to suggest that when we inquire about forms and formats of worship, we are asking the wrong questions. Rather than …

A Stochastic Sediment Delivery Model For A Steep Mediterranean Landscape, Emmanuel Gabet, Thomas Dunne

Faculty Publications

It is a truism in geomorphology that climatic events operate on a landscape to drive sediment transport processes, yet few investigations have formally linked climate and terrain characteristics with geomorphological processes. In this study, we incorporate sediment transport equations derived from fieldwork into a computer model that predicts the delivery of sediment from hillslopes in a steep Mediterranean landscape near Santa Barbara, California. The sediment transport equations are driven by rainstorms and fires that are stochastically generated from probability distributions. The model is used to compare the rates and processes of sediment delivery under two vegetation types: coastal sage scrub …

The New Economy Is Dead, Long Live The Information Economy, Phillip J. Bryson

Faculty Publications

The arrival of the 2001-2003 recession caused many to suppose that the so-called "New Economy" was now defunct. This article addresses a number of related issues, including the question of the durability and viability of business cycles in the face of the technological developments of the information age. It asks what went wrong with the New Economy and examines its characteristics as well as its remaining possibilities and prospects for the future. Finally, it considers the spread of the Information Economy to Europe, especially to Germany, the country that one might expect to be the leading European player, but which …

Scientific Collaboratories In Higher Education: Exploring Learning Style Preferences And Perceptions Of Technology, Diane H. Sonnenwald, Bin Li

Faculty Publications

Scientific collaboratories hold the promise of providing students access to specialized scientific instruments, data and experts, enabling learning opportunities perhaps otherwise not available. However, evaluation of scientific collaboratories in higher education has lagged behind their development. We conducted a repeated-measures study that provided data regarding social interaction learning styles and perceptions of a scientific collaboratory system from 40 university science students working face-to-face and remotely. Students with a strong competitive learning style preference or who worked with a student with a strong competitive learning style reported a slightly more positive perception of the relative advantage, compatibility and complexity of the …

Well Posed Constraint-Preserving Boundary Conditions For The Linearized Einstein Equations, Gioel Calabrese, Jorge Pullin, Oscar Reula, Olivier Sarbach, Manuel Tiglio

Faculty Publications

In this paper we address the problem of specifying boundary conditions for Einstein's equations when linearized around Minkowski space using the generalized Einstein-Christoffel symmetric hyperbolic system of evolution equations. The boundary conditions we work out guarantee that the constraints are satisfied provided they are satisfied on the initial slice and ensures a well posed initial-boundary value formulation. We consider the case of a manifold with a non-smooth boundary, as is the usual case of the cubic boxes commonly used in numerical relativity. The techniques discussed should be applicable to more general cases, as linearizations around more complicated backgrounds, and may …

Autonomous Vehicle Technologies For Small Fixed Wing Uavs, Derek B. Kingston, Randal Beard, Timothy Mclain, Michael Larsen, Wei Ren

Faculty Publications

Autonomous unmanned air vehicle flight control systems require robust path generation to account for terrain obstructions, weather, and moving threats such as radar, jammers, and unfriendly aircraft. In this paper, we outline a feasible, hierarchal approach for real-time motion planning of small autonomous fixed-wing UAVs. The approach divides the trajectory generation into four tasks: waypoint path planning, dynamic trajectory smoothing, trajectory tracking, and low-level autopilot compensation. The waypoint path planner determines the vehicle's route without regard for the dynamic constraints of the vehicle. This results in a significant reduction in the path search space, enabling the generation of complicated paths …

Modular Verification Of Timed Circuits Using Automatic Abstraction, Eric G. Mercer, Chris Myers, Hao Zheng

Faculty Publications

The major barrier that prevents the application of formal verification to large designs is state explosion. This paper presents a new approach for verification of timed circuits using automatic abstraction. This approach partitions the design into modules, each with constrained complexity. Before verification is applied to each individual module, irrelevant information to the behavior of the selected module is abstracted away. This approach converts a verification problem with big exponential complexity to a set of subproblems, each with small exponential complexity. Experimental results are promising in that they indicate that our approach has the potential of completing much faster while …

Dynamic Sociometry In Particle Swarm Optimization, Mark Richards, Dan A. Ventura

Faculty Publications

The performance of Particle Swarm Optimization is greatly affected by the size and sociometry of the swarm. This research proposes a dynamic sociometry, which is shown to be more effective on some problems than the standard star and ring sociometries. The performance of various combinations of swarm size and sociometry on six different test functions is qualitatively analyzed.

A Narrative Approach To Exploring Responsible Involvement Of Fathers With Their Special-Needs Children, David C. Dollahite

Faculty Publications

This chapter briefly summarizes the main findings from research employing narrative methodologies on fathers of children with special needs conducted by me and my students (Brotherson & Dollahite, 1997; Dollahite, 2003; Dollahite, Marks, & Brotherson, 1998; Dollahite, Marks, & Olson, 2002; Marks & Dollahite, 2001; Olson, Dollahite, & White, 2002). This research is consistent with recent emphasis on narrative methods in the social sciences generally (Dollahite, Hawkins, & Brotherson, 1996; Josselson & Lieblich, 1993; McAdams, 1993; Riessman, 1993; Sarbin, 1986) and with recent narrative studies of fathers of special-needs children (Brotherson, 1995) and fathers and religion, (Latshaw, 1998; Marshall, Olsen, …

Thirty-one students from the United States and 30 students from Europe participated in this program, which was by the U.S. Department of Education and the European Union. The project commenced with a 3-week meeting of faculty and students to design the 8-week exchange program and cultural preparation module. This article describes institutional issues …

Development And Evolution Of The Amniote Integument: Current Landscape And Future Horizon, Cheng Ming Chuong, Dominique G. Homberger

Faculty Publications

This special issue on the development and evolution of the amniote integument begins with a discussion of the adaptations to terrestrial conditions, the acquisition of water-impermeability by the reptilian integument, and the initial formation of filamentous integumentary appendages that pave the way towards avian flight. Recent feather fossils are reviewed and a definition of feathers is developed. Hierarchical models are proposed for the formation of complex structures, such as feathers. Molecular signals that alter the phenotype of integumentary appendages at different levels of the hierarchy are presented. Tissue interactions and the roles of keratins in evolution are discussed and linked …

High-Field Measurements Of Electron Decoherence Time In Metallic Nanowires: Switching Off Magnetic Impurity Spins, P. Mohanty, Richard A. Webb

Faculty Publications

We report low-temperature measurements of electron decoherence time in a series of pure gold wires, 18 nm thick and 30 nm wide. At fields up to 15 T, large enough to polarize any concentration of magnetic impurity spins, conductance fluctuation measurements show almost no temperature dependence of the decoherence time below 300 mK, both in the correlation field for interference and the root-mean-square value of the fluctuations. Combined with previous low-field weak localization measurements on samples from similar material, our experiment suggests that the ubiquitous saturation of decoherence time in these samples is not due to any mechanism based on …
