Probability And Agents, Marco Valtorta, Michael N. Huhns Jan 2001

Probability And Agents, Marco Valtorta, Michael N. Huhns

Faculty Publications

To make sense of the information that agents gather from the Web, they need to reason about it. If the information is precise and correct, they can use engines such as theorem provers to reason logically and derive correct conclusions. Unfortunately, the information is often imprecise and uncertain, which means they will need a probabilistic approach. More than 150 years ago, George Boole presented the logic that bears his name. There is concern that classical logic is not sufficient to model how people do or should reason. Adopting a probabilistic approach in constructing software agents and multiagent systems simplifies some …

Functional Projections Of Predicates: Experimental Evidence From Coordinate Structure Processing, Stanley William Dubinsky, Marie Egan, A. Rene Schumauder, Matthew J. Traxler Dec 2000

Functional Projections Of Predicates: Experimental Evidence From Coordinate Structure Processing, Stanley William Dubinsky, Marie Egan, A. Rene Schumauder, Matthew J. Traxler

Faculty Publications

This paper reports the results of six experiments involving an on-line self-paced reading task that examine the processing of coordinate small clause predicate phrases versus coordinated arguments NPs. The results have particular significance for the analysis of small clause complement constructions, and support accounts wherein the small clause complement has an Agr projection associated with it. An adequate explanation of the processing of small clause coordination is shown to motivate a new parsing principle, Coordination Feature-matching, which accounts for the longer reading times observed for the coordination of predicates in small clause complements.


Proteolytic Enzymes In The Marine Bacterium Pseudoalteromonas Atlantica: Post-Secretional Activation And Effects Of Environmental Conditions, Monica Hoffman, Alan W. Decho Dec 2000

Proteolytic Enzymes In The Marine Bacterium Pseudoalteromonas Atlantica: Post-Secretional Activation And Effects Of Environmental Conditions, Monica Hoffman, Alan W. Decho

Faculty Publications

Production and activities of cellular and extracellular proteolytic enzymes associated with the marine bacterium Pseudoalteromonas atlantica were examined in response to physiological state and changing environmental variables under laboratory conditions. Enzymes evidenced by zymography were metalloproteases, as defined by substrate preference and susceptibility to inhibitors (EDTA and 1, 10-phenanthroline). Distinct bands (i.e. molecular-weight [MW] size classes) of enzymes were isolated from within cellular and extracellular compartments. Susceptibility of extracellular enzymes to environmental stressors was related, in part, to the MW size classes of the enzymes. While all bands of enzymes showed some degree of inhibition when pH was decreased, the …


A Simple Surface Temperature Assimilation Scheme For Use In Land Surface Models, Venkataraman Lakshmi Dec 2000

A Simple Surface Temperature Assimilation Scheme For Use In Land Surface Models, Venkataraman Lakshmi

Faculty Publications

This paper examines the utilization of surface temperature as a variable which can be assimilated in off-line land surface hydrological models. The connection between the surface temperature and evapotranspiration is utilized in making adjustments to the model-computed surface soil moisture. This adjustment is a function of the difference between the model-computed and the observed surface temperature. Comparisons between the model-computed and satellite-observed surface temperatures have been carried out. The assimilation of surface temperature is carried out twice a day (corresponding to the A.M. and P.M. overpass of the NOAA 10) over the Red-Arkansas basin in the southwestern United States (31°50′N-36°N, …


The Use Of Uniaxial And Triaxial Accelerometers To Measure Children's "Free-Play" Physical Activity, Alise E. Ott, Russell R. Pate, Stewart G. Trost, Dianne S. Ward, Ruth P. Saunders Nov 2000

The Use Of Uniaxial And Triaxial Accelerometers To Measure Children's "Free-Play" Physical Activity, Alise E. Ott, Russell R. Pate, Stewart G. Trost, Dianne S. Ward, Ruth P. Saunders

Faculty Publications

In order to effectively measure the physical activity of children, objective monitoring devices must be able to quantify the intermittent and nonlinear movement of free play. The purpose of this study was to investigate the validity of the Computer Science and Applications (CSA) uniaxial accelerometer and the TriTrac-R3D triaxial accelerometer with respect to their ability to measure 8 "free-play" activities of different intensity. The activities ranged from light to very vigorous in intensity and included activities such as throwing and catching, hopscotch, and basketball. Twenty-eight children, ages 9 to 11, wore a CSA and a heart rate monitor while performing …

Effect Of Harvest And Effective Population Size On Genetic Diversity In A Striped Bass Population, Marilyn Diaz, David S. Wethey, James Bulak, Bert Ely Nov 2000

Effect Of Harvest And Effective Population Size On Genetic Diversity In A Striped Bass Population, Marilyn Diaz, David S. Wethey, James Bulak, Bert Ely

Faculty Publications

A major factor that contributes to loss of genetic variation in natural populations is a small effective population size. In species with a complex life history that involves overlapping generations and delayed maturity, the impact of infrequent annual reproductive bottlenecks is likely to be small because effective population size is defined by the number of individuals contributing to a generation and not to a single year-class. The striped bass Morone saxatilis is a longlived species with overlapping generations and age structure, whose recreational and commercial importance has made it a target of intense harvest.We analyzed allele frequency fluctuation among juvenile …


Emotion And Group Cohesion In Productive Exchange, Edward J. Lawler, Shane R. Thye, Jeongkoo Yoon Nov 2000

Emotion And Group Cohesion In Productive Exchange, Edward J. Lawler, Shane R. Thye, Jeongkoo Yoon

Faculty Publications

This study refines and experimentally tests a theory of relational cohesion that explains how and when actors become committed to one another in the context of multiactor exchange. The theory asserts that frequent social exchange results in (1) positive emotions that solidify and strengthen the person-to-group bond and (2) uncertainty reduction that renders the focal group more salient in relation to others. These two mechanisms produce a sense of psychological group formation and ultimately increase observable acts of commitment. In a “productive exchange” setting, three actors negotiate a joint venture that requires the assent of all members. The exchanges featured …

Faculty Publications

We report on the spectral dynamics of the reflectivity, site-selectively excited photoluminescence,photoluminescence excitation, and time-resolved luminescence in quaternary AlInGaN epitaxial layers grown on GaN templates. The incorporation of a few percents of In into AlGaN causes significant smoothening of the band-bottom potential profile in AlInGaN layers owing to improved crystal quality. An abrupt optical bandgap indicates that a nearly lattice-matched AlInGaN/GaN heterostructure with large energy band offsets can be grown for high-efficiency light-emitting devices.

Police Accountability And Early Warning Systems: Developing Policies And Programs, Geoffrey P. Alpert, Samuel Walker Oct 2000

Police Accountability And Early Warning Systems: Developing Policies And Programs, Geoffrey P. Alpert, Samuel Walker

Faculty Publications

The identification of police officers who have potential problems has emerged as a popular approach for curbing police misconduct and achieving accountability. Early warning (EW) systems are data-driven programs whose purpose is to identify officers whose behavior is problematic and to subject those officers to some kind of intervention, often in the form of counseling or training. Because of their potential for providing timely data on officer performance and giving police managers a framework for correcting unacceptable performance, early warning systems are consistent with the new demands for performance evaluation raised by community policing and the effective strategic management of …

Faculty Publications

Collagen molecules in articular cartilage have an exceptionally long lifetime, which makes them susceptible to the accumulation of advanced glycation end products (AGEs). In fact, in comparison to other collagen-rich tissues, articular cartilage contains relatively high amounts of the AGE pentosidine. To test the hypothesis that this higher AGE accumulation is primarily the result of the slow turnover of cartilage collagen, AGE levels in cartilage and skin collagen were compared with the degree of racemization of aspartic acid (% D-Asp, a measure of the residence time of a protein). AGE (Ne- (carboxymethyl)lysine, Ne-(carboxyethyl)lysine, and pentosidine) and % D-Asp concentrations increased …

Regulation Of Sup Expression Identifies Multiple Regulators Involved In Arabidopsis Floral Meristem Development, Hajime Sakai, Beth A. Krizek, Steven E. Jacobsen, Elliot M. Meyerowitz Sep 2000

Regulation Of Sup Expression Identifies Multiple Regulators Involved In Arabidopsis Floral Meristem Development, Hajime Sakai, Beth A. Krizek, Steven E. Jacobsen, Elliot M. Meyerowitz

Faculty Publications

During the course of flower development, floral homeotic genes are expressed in defined concentric regions of floral meristems called whorls. The SUPERMAN ( SUP, also called FLO10 ) gene, which encodes a C2H2-type zinc finger protein, is involved in maintenance of the stamen/carpel whorl boundary (the boundary between whorl 3 and whorl 4) in Arabidopsis. Here, we show that the regulation of SUP expression in floral meristems is complex, consisting of two distinct phases, initiation and maintenance. The floral meristem identity gene LEAFY ( LFY ) plays a role in the initiation phase through at least two pathways, which …


An Approximation To Miscible Fluid Flows In Porous Media With Point Sources And Sinks By An Eulerian-Lagrangian Localized Adjoint Method And Mixed Finite Element Methods, Hong Wang, Liang Dong, Richard E. Ewing, Stephen L. Lyons, Guan Qin Aug 2000

An Approximation To Miscible Fluid Flows In Porous Media With Point Sources And Sinks By An Eulerian-Lagrangian Localized Adjoint Method And Mixed Finite Element Methods, Hong Wang, Liang Dong, Richard E. Ewing, Stephen L. Lyons, Guan Qin

Faculty Publications

We develop an Eulerian–Lagrangian localized adjoint method (ELLAM)-mixed finite element method (MFEM) solution technique for accurate numerical simulation of coupled systems of partial differential equations (PDEs), which describe complex fluid flow processes in porous media. An ELLAM, which was shown previously to outperform many widely used methods in the context of linear convection-diffusion PDEs, is presented to solve the transport equation for concentration. Since accurate fluid velocities are crucial in numerical simulations, an MFEM is used to solve the pressure equation for the pressure and Darcy velocity. This minimizes the numerical difficulties occurring in standard methods for approximating velocities caused …


Children's Understanding Of The Concept Of Physical Activity, Stewart G. Trost, Angela M. Morgan, Ruth P. Saunders, Gwen A. Felton, Dianne S. Ward, Russell R. Pate Aug 2000

Children's Understanding Of The Concept Of Physical Activity, Stewart G. Trost, Angela M. Morgan, Ruth P. Saunders, Gwen A. Felton, Dianne S. Ward, Russell R. Pate

Faculty Publications

This study evaluated 4th-grade students' understanding of the concept of physical activity and assessed the effects of two interventions to enhance the students' understanding of this concept. Students were randomly assigned to 1 of 3 conditions: the video group (n=40) watched a 5-min video describing physical activity; the verbal group (n=42) listened to a generic description of physical activity; the control group received no instruction (n=45). Students completed a 17-item checklist testing their understanding of the concept of physical activity. Compared to controls, students in the verbal and video group demonstrated significantly higher checklist …


Pyridoxamine, An Inhibitor Of Advanced Glycation Reactions, Also Inhibits Advanced Lipoxidation Reactions: Mechanism Of Action Of Pyridoxamine, Joelle M. Onorato, Alicia J. Jenkins, Suzanne R. Thorpe, John W. Baynes Jul 2000

Pyridoxamine, An Inhibitor Of Advanced Glycation Reactions, Also Inhibits Advanced Lipoxidation Reactions: Mechanism Of Action Of Pyridoxamine, Joelle M. Onorato, Alicia J. Jenkins, Suzanne R. Thorpe, John W. Baynes

Faculty Publications

Maillard or browning reactions lead to formation of advanced glycation end products (AGEs) on protein and contribute to the increase in chemical modification of proteins during aging and in diabetes. AGE inhibitors such as aminoguanidine and pyridoxamine (PM) have proven effective in animal model and clinical studies as inhibitors of AGE formation and development of diabetic complications. We report here that PM also inhibits the chemical modification of proteins during lipid peroxidation (lipoxidation) reactions in vitro, and we show that it traps reactive intermediates formed during lipid peroxidation. In reactions of arachidonate with the model protein RNase, PM prevented modification …
