Batch Mode Active Learning And Its Applications To Medical Image Classification, Steven C. H. Hoi, Rong Jin, Jianke Zhu, Michael R. Lyu

Research Collection School Of Computing and Information Systems

The goal of active learning is to select the most informative examples for manual labeling. Most of the previous studies in active learning have focused on selecting a single unlabeled example in each iteration. This could be inefficient since the classification model has to be retrained for every labeled example. In this paper, we present a framework for "batch mode active learning" that applies the Fisher information matrix to select a number of informative examples simultaneously. The key computational challenge is how to efficiently identify the subset of unlabeled examples that can result in the largest reduction in the Fisher …

Effects Of Advancing Age On Er Calcium Regulation In Rat Superior Cervical Ganglia, Conwin Kodel Vanterpool

Loma Linda University Electronic Theses, Dissertations & Projects

Intracellular calcium ([Ca²⁺]i) release from endoplasmic reticulum (ER) stores plays an important role in cell signaling. These stores are rapidly refilled via voltage-gated calcium channels or spontaneously via store-operated calcium channels and subsequent pumping by ER Ca²⁺-ATPases. Calcium release is triggered by the activation of the ryanodine receptor (RyR) channels and their function is in part dependent on their expression. We analyzed the [Ca²⁺]i transients in fura 2-loaded superior cervical ganglion (SCG) cells from 6, 12, 20, and 24-month-old Fischer 344 rats for their ability to rapidly and spontaneously refill. For rapid refilling, the …

Bone Morphogenic Protein Induced Repair Of The Premaxillary Cleft, Rick J. Rawson

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study is to evaluate the bony augmentation of premaxillary clefts in humans using recombinant bone morphogenic protein (rhBMP-2) in a collagen sponge carrier. 12 patients with unilateral cleft alveolar ridges were evaluated pre- and 4 months postoperatively. 10 patients were repaired with rhBMP-2 while two others were grafted with anterior iliac crest particulate marrow cancellous bone (PMCB). Computed tomographic studies were used to evaluate preoperative alveolar cleft volumes, postoperative bone bridge volumes, and pre/post operative volume ratios.

A pre/post operative volume ratio for patients repaired with rhBMP-2 ranged from 24.1% to 90.6% with a mean of …

The Effect Of Calcium Hydroxide Pastes On Root Dentin Fracture Resistance, Kurt W. Sturz

Oral Medication With Florfenicol For Black Tiger Shrimps Penaeus Monodon, Nutcharnart Tipmongkolsilp, Yanin Limpanon, Benjamas Patamalai, Pischa Lusanandana, Janenuj Wongtavatchai

The Thai Journal of Veterinary Medicine

Florfenicol (FF) and Chloramphenicol (CAP) were tested for their in vitro antimicrobial activity against 102 Vibrio isolates from clinical cases. The Minimum Inhibitory Concentration (MIC) for both antimicrobials was ≤ 8 μg/ml suggesting that all of the tested isolates were susceptible to both antimicrobials. The observed MIC range of FF (0.5-4.0 μg/ml) was more potent than that of CAP (0.5-8.0 μg/ml). The activity of both antimicrobials was not substantially influenced by the addition of sea water (5 ppt salinity) to the test system. When considering the best type of antimicrobial for food producing animals and in vitro antivibrio activity, FF …

Posttraumatic Stress Disorder And Art Making, Kelly Andrews

EVMS School of Health Professions Theses & Dissertations

Over the course of history war has brought death and destruction to the men and women who have had to partake in combat. Through advances in technology more soldiers are able to return home alive, however they are not always physically or mentally intact. There are a large number of men and women returning home from the current conflict in the Middle East with increased Posttraumatic Stress Disorder symptoms. Those who return home as amputees will most likely have amplified PTSD symptoms as they are not only returning home with mental scars, but physical wounds.

The psychological impact of war …

Representation Of Head-Centric Flow In The Human Motion Complex., Jeroen Goossens, Sean P Dukelow, Ravi S Menon, Tutis Vilis, Albert V Van Den Berg

Brain and Mind Institute Researchers' Publications

Recent neuroimaging studies have identified putative homologs of macaque middle temporal area (area MT) and medial superior temporal area (area MST) in humans. Little is known about the integration of visual and nonvisual signals in human motion areas compared with monkeys. Through extra-retinal signals, the brain can factor out the components of visual flow on the retina that are induced by eye-in-head and head-in-space rotations and achieve a representation of flow relative to the head (head-centric flow) or body (body-centric flow). Here, we used functional magnetic resonance imaging to test whether extra-retinal eye-movement signals modulate responses to visual flow in …

Preliminary Results For A Monocular Marker-Free Gait Measurement System, Jane Courtney, Annraoi Depaor

Articles

This paper presents results from a novel monocular marker-free gait measurement system. The system was designed for physical and occupational therapists to monitor the progress of patients through therapy. It is based on a novel human motion capture method derived from model-based tracking. Testing is performed on two monocular, sagittal-view, sample gait videos – one with both the environment and the subject’s appearance and movement restricted and one in a natural environment with unrestricted clothing and motion. Results of the modelling, tracking and analysis stages are presented along with standard gait graphs and parameters.

Hierarchical Models For Combining Ecological And Case-Control Data, Sebastien Haneuse, Jon Wakefield

UW Biostatistics Working Paper Series

The ecological study design suffers from a broad range of biases that result from the loss of information regarding the joint distribution of individual-level outcomes, exposures and confounders. The consequent non-identifiability of individual-level models cannot be overcome without additional information; we combine ecological data with a sample of individual-level case-control data. The focus of this paper is hierarchical models to account for between-group heterogeneity. Estimation and inference pose serious compu- tational challenges. We present a Bayesian implementation, based on a data augmentation scheme where the unobserved data are treated as auxiliary variables. The methods are illustrated with a dataset of …

An Added Dimension To The Faculty Role: The Accelerated Student, Lisa Rauch, Deborah Nelson

Master's Projects

Nursing faculty work hard at helping students achieve academic success by utilizing a variety of support services. The question guiding this study is: Do accelerated and traditional BSN students have different characteristics or different valued support services? The characteristics of accelerated and traditional BSN students were obtained from a larger longitudinal study (N=93). The Support Services Questionnaire collected data from a convenient sample of two groups of BSN students: accelerated (n=26), traditional (n=49). The results presented accelerated students as primarily female, financially supported, and holding a variety of college degrees. Traditional students were represented as female, younger, working and not …

Distinct P53 Acetylation Cassettes Differentially Influence Gene-Expression Patterns And Cell Fate., Chad D Knights, Jason Catania, Simone Di Giovanni, Selen Muratoglu, Ricardo Perez, Amber Swartzbeck, Andrew A Quong, Xiaojing Zhang, Terry Beerman, Richard Pestell, Maria Laura Avantaggiati

Kimmel Cancer Center Faculty Papers

The activity of the p53 gene product is regulated by a plethora of posttranslational modifications. An open question is whether such posttranslational changes act redundantly or dependently upon one another. We show that a functional interference between specific acetylated and phosphorylated residues of p53 influences cell fate. Acetylation of lysine 320 (K320) prevents phosphorylation of crucial serines in the NH(2)-terminal region of p53; only allows activation of genes containing high-affinity p53 binding sites, such as p21/WAF; and promotes cell survival after DNA damage. In contrast, acetylation of K373 leads to hyperphosphorylation of p53 NH(2)-terminal residues and enhances the interaction with …

Emotion And The Law: A Framework For Inquiry, Richard L. Wiener, Brian H. Bornstein, Amy Voss

Department of Psychology: Faculty Publications

This paper draws on research in social and cognitive psychology to show how theories of judgment and decision making that incorporate decision makers’ affective responses apply to legal contexts. It takes 2 widely used models of decision making, the rational actor and lens models, and illustrates their utility for understanding legal judgments by using them to interpret research findings on juror decision making, people’s obedience to the law (e.g., paying taxes), and eyewitness memory. The paper concludes with a discussion of the advantages of modifying existing approaches to information processing to include the influence of affect on how legal actors …

Feasibility Of Gdaha Hospitals Meeting The Surge Capacity And Capability Requirements Of An Avian Flu Pandemic In The Miami Valley, Raymond P. Ten Eyck

Master of Public Health Program Student Publications

Hospital surge capacity is a crucial portion of disaster preparedness planning within a community. The demands generated by a disaster require additional capacity, in the form of beds, equipment, personnel, and special capabilities. The scope and urgency of these requirements must be balanced with a practical approach addressing cost and space concerns. The advent of new infectious disease threats, particularly an avian flu pandemic, have reinforced the need to be prepared for a prolonged surge, lasting six to eight weeks, in addition to the shorter duration surges required for industrial accidents, tornados, chemical disasters and terrorists. Using a standardized data …

Mugshot Exposure Effects: Retroactive Interference, Mugshot Commitment, Source Confusion, And Unconscious Transference, Kenneth A. Deffenbacher, Brian H. Bornstein, Steven D. Penrod

Department of Psychology: Faculty Publications

More than 25 years of research has accumulated concerning the possible biasing effects of mugshot exposure to eyewitnesses. Two separate metaanalyses were conducted on 32 independent tests of the hypothesis that prior mugshot exposure decreases witness accuracy at a subsequent lineup. Mugshot exposure both significantly decreased proportion correct and increased the false alarm rate, the effect being greater on false alarms. A mugshot commitment effect, arising from the identification of someone in a mugshot, was a substantial moderator of both these effects. Simple retroactive interference, where the target person is not included among mugshots and no one in a mugshot …

Desulfovibrio Desulfuricans G20 Tetraheme Cytochrome Structure At 1.5 A˚ And Cytochrome Interaction With Metal Complexes, Mrunalini Pattarkine, J J. Tanner, C A. Bottoms, Y H. Lee, Judy D. Wall

Faculty Works

The structure of the type I tetraheme cytochrome c3 from Desulfovibrio desulfuricans G20 was determined to 1.5 A˚ by X-ray crystallography. In addition to the oxidized form, the structure of the molybdate-bound form of the protein was determined from oxidized crystals soaked in sodium molybdate. Only small structural shifts were obtained with metal binding, consistent with the remarkable structural stability of this protein. In vitro experiments with pure cytochrome showed that molybdate could oxidize the reduced cytochrome, although not as rapidly as U(VI) present as uranyl acetate. Alterations in the overall conformation and thermostability of the metal-oxidized protein were investigated …

Recruitment Of Bad By The Chlamydia Trachomatis Vacuole Correlates With Host-Cell Survival, Philippe Verbeke, Lynn Welter-Stahl, S. Ying, J. Hansen, Georg Hacker, Toni Darville, David M. Ojcius

All Dugoni School of Dentistry Faculty Articles

Chlamydiae replicate intracellularly in a vacuole called an inclusion. Chlamydial-infected host cells are protected from mitochondrion-dependent apoptosis, partly due to degradation of BH3-only proteins. The host-cell adapter protein 14-3-3β can interact with host-cell apoptotic signaling pathways in a phosphorylation-dependent manner. In Chlamydia trachomatis-infected cells, 14-3-3β co-localizes to the inclusion via direct interaction with a C. trachomatis-encoded inclusion membrane protein. We therefore explored the possibility that the phosphatidylinositol-3 kinase (PI3K) pathway may contribute to resistance of infected cells to apoptosis. We found that inhibition of PI3K renders C. trachomatis-infected cells sensitive to staurosporine-induced apoptosis, which is accompanied by mitochondrial cytochrome c …
