Unified Hybrid Censoring Samples From Power Pratibha Distribution And Its Applications, Mahmoud Mansour, Hebatalla H. Mohammad Dr, Khalaf S. Sultan Prof.

Basic Science Engineering

This paper suggests an extensive inferential method for the Power Pratibha Distribution (PPD) under Unified Hybrid Censoring Schemes (UHCSs), since there is a growing interest in flexible models in both reliability and service operations. This work studies the PPD model using standard Maximum Likelihood Estimation methods and modern Bayesian approaches too. Using a complex architecture, UHCS simulates tests more closely to what is done in practice than by using more basic censoring schemes. Using analysis, the probability and statistical ranges are carefully calculated for the parameters. Tests demonstrate that Bayesian estimation gives better results than many other methods for estimation, …

Acute Effect Of A Multi-Ingredient Pre-Workout Supplement On Pacing And Kinetic Expression During Shorter And Longer Bouts Of High Intensity Functional Training, Gerald Mangine, Christopher Staples, James W. Henley, Ashley Hines, Kristyn C. Mcgeehan, Wysmark Chaves, Wil King, Tiffany A. Esmat, John R. Mclester, Jacob L. Grazer

Faculty Articles

Background: High-intensity functional training (HIFT) varies daily workout programming, and trainees are often tasked with completing “as many repetitions as possible” (AMRAP) within a set time. Successful performance depends on fatigue management skills and maintaining a consistent expression of force and velocity when performing and transitioning between exercises over the duration of the workout. Multi-ingredient preworkout (MIPS) supplement formulations often contain ingredients shown to facilitate energy availability and mitigate fatigue, and therefore, might positively affect HIFT performance. This study aimed to assess a multi-ingredient pre-workout supplement’s acute effect on pacing and the expression of kinetics throughout a 5- and 15-minute …

Current Continuity In Auroral System Science, Jules Van Irsel

Dartmouth College Ph.D Dissertations

The Earth relies on the Sun's energy, but at times this energy can be overwhelming; the Sun expels plasma which, were it not for our humble magnetic field, would erode our atmosphere (Mars, c. 4 Ga). The protective interaction Earth has with the solar wind results in spectacular auroral displays---one such auroral form is discussed in this thesis: quiet discrete auroral arcs.

Such arcs have long been studied; they are abundant, have usable symmetries, and they can predict magnetic substorms that wreak havoc in our magnetosphere. The auroral emissions, albeit beautiful, are however only the visible end of a self-consistent …

The Benefits Of Exercise Training In Combination With Weight Loss Therapies

Faculty, Staff and Students Publications

The primary treatment for obesity involves calorie restriction (CR) to promote dietary weight loss achieved through interventions including behavioral modification, bariatric surgery, and antiobesity medications. In adults with obesity, CR-induced weight loss enhances physical function and improves quality of life, while also reducing the burden of various obesity-related chronic conditions, including hypertension, diabetes, obstructive sleep apnea, and atherosclerotic heart disease. However, it is also associated with a decline in lean mass and bone mineral density, which increases the risk of sarcopenia and osteoporosis. When performed alongside CR, progressive resistance training (RT) attenuates this loss of lean mass and bone mass, …

Psilocybin Treatment Extends Cellular Lifespan And Improves Survival Of Aged Mice, Cristian Coarfa, Ali J Zarrabi, Louise Hecker

Faculty, Staff and Students Publications

Psilocybin, the naturally occurring psychedelic compound produced by hallucinogenic mushrooms, has received attention due to considerable clinical evidence for its therapeutic potential to treat various psychiatric and neurodegenerative indications. However, the underlying molecular mechanisms remain enigmatic, and few studies have explored its systemic impacts. We provide the first experimental evidence that psilocin (the active metabolite of psilocybin) treatment extends cellular lifespan and psilocybin treatment promotes increased longevity in aged mice, suggesting that psilocybin may be a potent geroprotective agent.

CD16A is an activating Fc receptor on NK cells that mediates antibody-dependent cellular cytotoxicity (ADCC), a key mechanism in antiviral immunity. However, the role of NK cell-mediated ADCC in SARS-CoV-2 infection remains unclear, particularly whether it limits viral spread and disease severity or contributes to the immunopathogenesis of COVID-19. We hypothesized that the high-affinity CD16AV176 polymorphism influences these outcomes. Using an in vitro reporter system, we demonstrated that CD16AV176 is a more potent and sensitive activator than the common CD16AF176 allele. To assess its clinical relevance, we analyzed 1,027 patients hospitalized with COVID-19 from the Immunophenotyping Assessment in a COVID-19 …

Edge-Streamer: A Lightweight, Self-Supervised Event Segmentation Model, Lucas Miller

USF Tampa Graduate Theses and Dissertations

Event segmentation is the practice of autonomously detecting the boundaries of semantically connected sequences of actions within a video. It is connected to many areas of computer vision, including action recognition and event understanding. Nearly all current work requires the entire video to be stored in memory to be processed in multiple passes. This takes up valuable resources, increases processing time, prevents the use of low-power, low-memory devices, and precludes long-form content and live videos from undergoing event segmentation.

This thesis introduces EDGE-STREAMER, a real-time, lightweight, self-supervised, transformer architecture capable of performing event segmentation in a single pass. EDGE-STREAMER uses …

Design For Additive Manufacturing: Simultaneous Optimization Of Structural Integrity And Minimal Support Structures, Naresh Ahuja

Doctoral Dissertations and Master's Theses

This dissertation addresses two core challenges limiting the widespread application of Topology Optimization (TO): the difficulty in fabricating its complex designs, especially for Additive Manufacturing (AM), and its significant computational costs. It develops a unified design framework that directly embeds AM constraints such as overhang angles and build direction into robust TO formulations. To enhance manufacturability, two distinct methodologies are proposed. Firstly, a Solid Isotropic Material with Penalization (SIMP) framework introduces a three-stage robust optimization algorithm. Secondly, the Geometric Projection Topology Optimization (GPTO) method inherently integrates overhang constraints by controlling individual geometric components and their inclined angles relative to a …

Food Noise: Definition, Measurement, And Future Research Directions, Emily J Dhurandhar, Kevin C Maki, Nikhil V Dhurandhar, Theodore K Kyle, Sydney Yurkow, Misty A W Hawkins, Jon Agley, Emily H Ho, Lawrence J Cheskin, Thorkild I A Sørensen, Xi Rita Wang, David B Allison

Children’s Nutrition Research Center Staff Publications

The term food noise has been recently popularized by individuals managing their weight or adhering to specific diets for health reasons. Anecdotal evidence from patients and clinical observations suggests that food noise involves constant preoccupation with food-related decisions-such as which foods to eat, caloric intake, macronutrient balance, and meal timing-which can become intrusive and unpleasant. Food noise also appears to affect cognitive burden and quality of life, and is being cited as one reason weight-loss attempts fail. The increase in public discourse about food noise has highlighted its potential significance, yet a formal clinical definition and method of measurement of …

Magnetic Field Enabled Assembly And Propulsion Of Colloidal Particles In A Magnetic Medium, Hashir M. Gauri

LSU Doctoral Dissertations

Colloidal particles are nano/micro meter-sized particles dispersed in a fluid medium and serve as diverse building blocks for assembling complex structures. The ease of tunability of the shape, size, and interparticle interactions of colloidal particles facilitates their assembly into rich structures and phases that mirror the assembly process of atomic systems. Often regarded as "big atoms" colloidal particles provide an ideal model system for investigating complex phenomena in condensed matter, such as crystallization and nucleation. While the assembly of colloids under thermodynamic equilibrium has been extensively studied, recent interest has shifted toward exploring colloids in non-equilibrium conditions to create dynamic …

Mtor Signaling Regulates The Development Of Airway Mucous Cell Metaplasia Associated With Severe Asthma, Katrina M. Kudrna, Luis F. Vilches, Evan M. Eilers, Shailendra K. Maurya, Steven L. Brody, Amjad Horani, Kristina L. Bailey, Todd A. Wyatt, John D. Dickinson

2020-Current year OA Pubs

In asthma, airway epithelial remodeling is characterized by aberrant goblet cell metaplastic differentiation accompanied by epithelial cell hyperplasia and hypertrophy. These pathologic features in severe asthma indicate a loss of control of proliferation, cell size, differentiation, and migration. MTOR is a highly conserved pathway that regulates protein synthesis, cell size, and proliferation. We hypothesized that the balance between MTOR and autophagy regulates mucous cell metaplasia. Airways from individuals with severe asthma showed increased MTOR signaling by RPS6 phosphorylation, which was reproduced using an IL-13-activated model of primary human airway epithelial cells (hAEC). MTOR inhibition by rapamycin led to a decrease …
