Simulation Research On Influence Of Blood Flow On Heating During Hifu Treatment, Suqin Dai, Shengyou Qian, Yaosheng Gui, Xiao Sheng

Journal of System Simulation

Abstract: When blood vessel exists in the tumor tissue, and its boundary portion close to the vessel will be strongly influenced by the cooling effect of the blood vessel. This influence will lead to the incomplete cancer treatment. To study the influence of blood flow on heating towards the above situation, concave spherical transducer was used as the heat source, and sound intensity distribution was obtained by Rayleigh integral. Pennes equation was solved with finite difference method, then the dose distribution was calculated to determine the thermal damage degree of tissue using quantitative relationship between the heating time and temperature. …

OBJECTIVE: Uncoupling protein 3 (UCP3) is a mitochondrial carrier related to fatty acid metabolism. Although gene variants of UCP3 are associated with human obesity, their contribution to increased adiposity remains unclear. This study investigated the impact that loss of UCP3 has on diet-induced obesity in rats.

METHODS: Male UCP3 knockout rats (ucp3

RESULTS: Loss of UCP3 decreased fat mass gain, white adipocytes size, and systemic inflammation. The ucp3

CONCLUSIONS: Loss of UCP3 partially protects rats from diet-induced obesity. This phenotype is related to induction of a compensatory antioxidant mechanism and prevention of iBAT whitening.

Promoting Resident Emotional Health Meaningful Connections: An Evaluation Of A Wellness Game, Bruce St. Amour, William B. Dehart

Journal of Wellness

Introduction

Physician wellness is a topic of significant national interest. Physician burnout is at its highest point during residency and is linked to many negative outcomes. The Core Emotional Needs are a useful framework to guide thinking toward wellness in residents: connection and acceptance, healthy autonomy and performance, reasonable limits, and healthy responsibility and standards. We examined the efficacy of a game (“Well, For Me…”) designed to improve social connection and acceptance among residents to reduce social isolation. We hypothesized that this activity would be viewed positively by the residents as an intervention to improve resident wellness.

Detectif: Unified Detection And Correction Of Iot Faults In Smart Homes, Madhumita Maliick, Archan Misra, Niloy Ganguly, Youngki Lee

Research Collection School Of Computing and Information Systems

This paper tackles the problem of detecting a comprehensive set of sensor faults that can occur in IoT-instrumented smart homes customized to infer Activities of Daily Living (ADL) from the activation of sensor sets. Specifically, sensors can suffer faults that (a) span durations that vary between several seconds to hours, (b) can result in both missing or false-alarm sensor-events. Previous fault detection approaches are geared primarily to identify missing faults (absence of sensor readings) of a permanent (very long-lived) nature, or sporadic false-alarm events. We propose DetectIF, a fault-detection framework that detects faults of varying time duration, and identifies both …

Gamifying Place, Reimagining Publicness: The Heterotopic Inscriptions Of Pokémon Go, Orlando Woods

Research Collection School of Social Sciences

This paper explores the transformative effects of augmented reality mobile games on society and space. By layering playfulness onto public space through a digital interface, augmented reality mobile games create a pervasive sense of play that can be accessed by players potentially anywhere, and at any time. Games like these can therefore be understood as heterotopic inscriptions on otherwise mundane environments. Since being released in 2016, Pokémon Go has become one of the most popular augmented reality games in the world. It gamifies place by embedding digital objects within public spaces; in doing so, it can bring about a reimagination …

Masculinized Second-To-Fourth Digit Ratio (2d:4d Ratio) Is Associated With Lower Cortisol Response In Infant Female Rhesus Monkeys (Macaca Mulatta), Elizabeth K. Wood, Parker Jarman, Elysha Cash, Alexander Baxter, John P. Capitanio, James Dee Higley

Faculty Publications

The second-to-fourth digit ratio (2D:4D ratio) is considered a postnatal proxy measure for the degree of prenatal androgen exposure (PAE), which is the primary factor responsible for masculinizing the brain of a developing fetus. Some studies suggest that the organizational effects of PAE may extend to the hypothalamic-pituitary-adrenal (HPA) axis response to stress. This study investigates the relationship between 2D:4D ratio and HPA axis functioning using a rhesus monkey (Macaca mulatta) model. Subjects were N = 268 (180 females, 88 males) rhesus monkey infants (3–4 months of age). Plasma cortisol concentrations were assayed from two blood samples obtained …

Application Of Quantum-Markov Open System Models To Human Cognition And Decision, Jerome Busemeyer, Qizi Zhang, S. N. Balakrishnan, Zheng Wang

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Markov processes, such as random walk models, have been successfully used by cognitive and neural scientists to model human choice behavior and decision time for over 50 years. Recently, quantum walk models have been introduced as an alternative way to model the dynamics of human choice and confidence across time. Empirical evidence points to the need for both types of processes, and open system models provide a way to incorporate them both into a single process. However, some of the constraints required by open system models present challenges for achieving this goal. The purpose of this article is to address …

The Quest Of Love: A Liturgical Reading Of The Pilgrim's Progress, Matthew Charles Fox

Masters Theses

John Bunyan’s The Pilgrim’s Progress has been enjoyed for its imaginative story by a wide variety of readers since its publication in 1678, but criticism has long treated Bunyan’s imaginative story-telling as separate from and at odds with his Puritanism. If this were the case and expositing theological doctrine was Bunyan’s main purpose, then why would he write a fiction? Using James K. A. Smith idea of “liturgical pedagogy” from his Cultural Liturgies series, this thesis argues that Bunyan’s story does more than vividly convey theological doctrine to the reader’s mind; rather, it captures the imagination of the reader’s heart, …

Sodium Butyrate Reduces Salmonella Enteritidis Infection Of Chicken Enterocytes And Expression Of Inflammatory Host Genes In Vitro, Anamika Gupta, Mohit Bansal, Basanta Raj Wagle, Xiaolun Sun, Narayan Rath, Annie Donoghue, Abhinav Upadhyay

Poultry Science Faculty Publications and Presentations

Salmonella Enteritidis (SE) is a facultative intracellular pathogen that colonizes the chicken gut leading to contamination of carcasses during processing. A reduction in intestinal colonization by SE could result in reduced carcass contamination thereby reducing the risk of illnesses in humans. Short chain fatty acids such as butyrate are microbial metabolites produced in the gut that exert various beneficial effects. However, its effect on SE colonization is not well known. The present study investigated the effect of sub-inhibitory concentrations (SICs) of sodium butyrate on the adhesion and invasion of SE in primary chicken enterocytes and chicken macrophages. In addition, the …

Suitability Of Resampled Multispectral Datasets For Mapping Flowering Plants In The Kenyan Savannah, David Masereti Makori, Elfatih M. Abdel-Rahman, Tobias Landmann, Onisimo Mutanga, John Odindi, Evelyn Nguku, Henry E. Tonnang, Suresh Raina

All Peer-Reviewed Publications

Pollination services and honeybee health in general are important in the African savannahs particularly to farmers who often rely on honeybee products as a supplementary source of income. Therefore, it is imperative to understand the floral cycle, abundance and spatial distribution of melliferous plants in the African savannah landscapes. Furthermore, placement of apiaries in the landscapes could benefit from information on spatiotemporal patterns of flowering plants, by optimising honeybees’ foraging behaviours, which could improve apiary productivity. This study sought to assess the suitability of simulated multispectral data for mapping melliferous (flowering) plants in the African savannahs. Bi-temporal AISA Eagle hyperspectral …

Neurotoxicity Of Isomers Of The Environmental Toxin L-Bmaa, Thomas Schneider, Catherine Simpson, Prachi Desai, Madeleine Tucker, Doug Lobner

Biomedical Sciences Faculty Research and Publications

There is evidence that the environmental toxin β-N-methylamino-L-alanine (L-BMAA) may be involved in neurodegenerative diseases. However, a number of controversies exist regarding L-BMAA, one of which is the possibility that when assaying for L-BMAA, its isomers are being detected instead. There are at least four isomers of BMAA that are known to occur: L-BMAA, β-N-methylamino-D-alanine (D-BMAA), 2,4-diaminobutyric acid (DAB), and N-(2-aminoethyl)glycine (AEG). The fact that isomers of BMAA exist in nature also leads to the possibility that they are involved in toxicity. We set out to determine both the potency and the mechanism of toxicity of L-BMAA, D-BMAA, DAB, and …

The Relationship Among Children Born With A Congenital Heart Defect, Effects Of General Anesthesia, And Special Academic Needs, Lorilynn Bowie

Dissertations

Abstract

I initiated this study due to experience in the public education system in one state in the United States. I noted a lack of understanding among educators on how to meet the educational needs of children born with a congenital heart defect (CHD) who had undergone general anesthesia related to their CHD. A lack of communication between the medical sector and the educational world led to extensive delays in children receiving the educational support they needed to be successful academically. There were two primary exploratory questions that drove my study: 1.) Is there a relationship between children born with …

Functions Of Fibroblast Growth Factor Homologous Factor 2 In Excitable Tissues, Christopher Marra

Dissertations, Theses, and Capstone Projects

Purpose: Fibroblast Growth Factor Homologous Factors (FHFs) are a group of proteins known to associate with and modulate voltage-gated sodium channels (Na_v) in excitable cells. The four FHF genes are differentially expressed in specific cell-types, with FHF2 expressed prominently in the hippocampus, cerebral cortex, heart and dorsal root ganglia. Due to previous unavailability of an Fhf2 knockout mouse, this gene’s functions have been understudied in comparison to other those encoding other FHFs. The purpose of this research has been to better understand the normal physiological functions of FHF2 at the cellular and system levels in the heart, sensory …

Emotion In Mind, Kathryn E. Pendoley

Dissertations, Theses, and Capstone Projects

Emotions consume our thoughts and drive our actions. If you had different emotions, or no emotions at all, the way you move in the world and understand your place in it would be completely different. We need a satisfactory theory of emotion for a complete science of the mind. In this dissertation, I consider two of the most compelling theories of emotion: broad perceptualism – the view that emotions either are themselves perceptual or include a perceptual aspect as at least a part – and constructionism – the theory that emotions are self-interpretive thoughts. I find that perceptualist thinking fails …

360º Video And Language Documentation: Towards A Corpus Of Kanien'kéha (Mohawk), Joseph Pentangelo

Dissertations, Theses, and Capstone Projects

Robust documentation is a major goal of documentary linguistics. Recognizing spoken language as a multimodal phenomenon, researchers working in this field broadly agree that video is an improvement over audio-only recording. At the same time, video is limited by the format’s frame, which permits only a relatively small portion of the visual field to be recorded at any given time. This results in much data being lost, as the documenter must decide where to aim their camera, necessarily leaving out more than they record.

In this dissertation, I apply 360º video to language documentation for the first time. 360º video, …

The Women That No One Wanted To See: The Duality Of The Women Within The Holocaust, Valerie Cabezas-Iacono

Dissertations, Theses, and Capstone Projects

This paper is a brief historiography of the complexities of unraveling how gender constructs inform how society perceives both female perpetrators of the Third Reich and victims of sexual assault during the Holocaust. The women within these categories experienced vastly different power dynamics from 1939-1945 with the implementation of anti-Semitic ideology that would go on to forge the genocidal policies of the Nazi State. Seemingly, Aryan and Jewish women had no traits that linked them besides their biological sex, and this one factor determined how their experiences would translate within the male-centered discourse of the Holocaust. The framework of Holocaust …
