Comparative Trust Management With Applications: Bayesian Approaches Emphasis, Krishnaprasad Thirunarayan, Pramod Anantharam, Cory Andrew Henson, Amit P. Sheth

Kno.e.sis Publications

Trust relationships occur naturally in many diverse contexts such as collaborative systems, e-commerce, interpersonal interactions, social networks, and semantic sensor web. As agents providing content and services become increasingly removed from the agents that consume them, the issue of robust trust inference and update becomes critical. There is a need to find online substitutes for traditional (direct or face-to-face) cues to derive measures of trust, and create efficient and robust systems for managing trust in order to support decision-making. Unfortunately, there is neither a universal notion of trust that is applicable to all domains nor a clear explication of its …

Cursing In English On Twitter, Wenbo Wang, Lu Chen, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

Cursing is not uncommon during conversations in the physical world: 0.5% to 0.7% of all the words we speak are curse words, given that 1% of all the words are first-person plural pronouns (e.g., we, us, our). On social media, people can instantly chat with friends without face-to-face interaction, usually in a more public fashion and broadly disseminated through highly connected social network. Will these distinctive features of social media lead to a change in people's cursing behavior? In this paper, we examine the characteristics of cursing activity on a popular social media platform - Twitter, involving the analysis of …

The Preliminary Study Of Effects Of Tolfenamic Acid On Cell Proliferation, Cell Apoptosis, And Intracellular Collagen Deposition In Keloid Fibroblasts In Vitro, Dan Yi, Mackenzie S. Newman, Yanfang Chen, Richard Simman

Pharmacology and Toxicology Faculty Publications

Keloid scarring is a fibroproliferative disorder due to the accumulation of collagen type I. Tolfenamic acid (TA), a nonsteroidal anti-inflammatory drug, has been found to potentially affect the synthesis of collagen in rats. In this preliminary study, we aimed to test the effects of TA on cell proliferation, cell apoptosis, and the deposition of intracellular collagen in keloid fibroblasts. Normal fibroblasts (NFs) and keloid fibroblasts (KFs) were obtained from human dermis tissue. Within the dose range 10−3–10−6 M and exposure times 24 h, 48 h, and 72 h, we found that 0.55 × 10−3 M TA at 48 h exposure …

Ultraviolet Rayleigh Scatter Imaging For Spatial Temperature Profiles In Atmospheric Microdischarges, James E. Caplinger

Browse all Theses and Dissertations

Spatially resolved temperature measurements within a microdischarge in atmospheric pressure air have been conducted using Rayleigh scattering of a pulsed ultraviolet laser. Scattering intensity images were used to generate a radial profile of translational temperature, with the analysis based on the ideal gas inverse relationship of temperature and gas density. Rayleigh scattering results were compared to standard optical emission spectral analyses of N2(C3Πu - B3Πg) bands, where the calculated rotational temperatures from emission were in reasonable agreement with the Rayleigh translational temperature profiles.

Tcdd Represses 3'IghRr Activation Through An Ahr-Dependent Shift In The Nf-Κb/Rel Protein Complexes Binding To Κb Motifs Within The Hs1,2 And Hs4 Enhancers, Richard L. Salisbury Jr.

Browse all Theses and Dissertations

Transcriptional regulation of the murine immunoglobulin heavy chain gene involves several regulatory elements including the 3'Igh regulatory region (3'IghRR) composed of at least four enhancers (hs3A; hs1,2; hs3B; hs4). Enhancers hs1,2 and hs4 contain binding sites for several transcription factors including NF-κB/Rel proteins and the AhR. Interestingly, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) profoundly inhibits 3'IghRR and hs1,2 activation induced by the B-cell activator lipopolysaccharide (LPS), but enhances the activation of the hs4. Within the hs4, the AhR binding site overlaps an NF-κB/Rel binding site suggesting that both the AhR and the NF-κB together may modulate of the 3' …

A Comparison Of Monocular Camera Calibration Techniques, Richard L. Van Hook

Browse all Theses and Dissertations

Extensive use of visible electro-optical (visEO) cameras for machine vision techniques shows that most camera systems produce distorted imagery. This thesis investigates and compares several of the most common techniques for correcting the distortions based on a pinhole camera model. The methods being examined include a common chessboard pattern based on (Sturm 1999), (Z. Zhang 1999), and (Z. Zhang 2000), as well as two "circleboard" patterns based on (Heikkila 2000). Additionally, camera models from the visual structure from motion (VSFM) software (Wu n.d.) are used. By comparing reprojection error from similar data sets, it can be shown that the asymmetric …

Day-Of-Discharge Planning At Acute Care Hospitals, Kylie M. Bertsch

Browse all Theses and Dissertations

Hospitals provide a complex array of services to patient populations with highly variable conditions, needs, and preferences. These services are delivered with limited resources, and therefore, the synchronization of patient flow between various units in the hospital is essential for minimizing patient delay and congestion. Unfortunately, patient flow optimization is a topic in its research infancy, and, in current practice, hospitals struggle with the numerous ramifications of delays in care provision and increased costs. Emergency Department (ED) crowding and boarding have become a topic of increased interest as the ED becomes an increasingly popular entry point to acute care hospitals. …

The Role Of The Nurse In Family Coping After Miscarriage, Wesley Hannebaum

Celebration of Undergraduate & Graduate Research, Scholarship, and Creative Activities Materials

When a miscarriage occurs, it affects the entire family unit, making coping an important part of healing during this time. After miscarriage, women are at increased risk for developing mental disorders such as anxiety and depression. Miscarriage is seldom seen as a concern for the father of the lost child, and thus their feelings are often ignored. It is important for the nurse to know how to best help these men, women, and the rest of the involved family cope after miscarriage so they can move on in a healthy way. The following is a review of the literature to …

Piwi Homologs Mediate Histone H4 Mrna Localization To Planarian Chromatoid Bodies, Labib Rouhana, Jennifer A. Weiss, Ryan S. King, Phillip A. Newmark

Biological Sciences Faculty Publications

The well-known regenerative abilities of planarian flatworms are attributed to a population of adult stem cells called neoblasts that proliferate and differentiate to produce all cell types. A characteristic feature of neoblasts is the presence of large cytoplasmic ribonucleoprotein granules named chromatoid bodies, the function of which has remained largely elusive. This study shows that histone mRNAs are a common component of chromatoid bodies. Our experiments also demonstrate that accumulation of histone mRNAs, which is typically restricted to the S phase of eukaryotic cells, is extended during the cell cycle of neoblasts. The planarian PIWI homologs SMEDWI-1 and SMEDWI-3 are …

Is There Light After Depth? Distribution Of Periphyton Chlorophyll And Productivity In Lake Littoral Zones, Yvonne Vadeboncoeur, Shawn P. Devlin, Peter B. Mcintyre, M. J. Vander Zanden

Biological Sciences Faculty Publications

Periphyton and phytoplankton contribute to the base of lake food webs, and both groups of microalgae are influenced by resources and physical forcing. Spatial variation in light availability interacts with the physical dynamics of the water column to create predictable depth gradients in resources and disturbance that may differentially affect periphyton vs phytoplankton. We characterized the depth distribution of chlorophyll and productivity of periphyton on sediments (epipelon) and phytoplankton in the euphotic zones of 13 oligomesotrophic lakes that span a large size gradient (0.017–32,600 km²). Epipelic chlorophyll usually increased with depth in the epilimnion. Light was the primary …
