Transfer-To-Transfer Learning Approach For Computer Aided Detection Of Covid-19 In Chest Radiographs, Barath Narayanan Narayanan, Russell C. Hardie, Vignesh Krishnaraja, Christina Karam, Venkata Salini Priyamvada Davuluru

Electrical and Computer Engineering Faculty Publications

The coronavirus disease 2019 (COVID-19) global pandemic has severely impacted lives across the globe. Respiratory disorders in COVID-19 patients are caused by lung opacities similar to viral pneumonia. A Computer-Aided Detection (CAD) system for the detection of COVID-19 using chest radiographs would provide a second opinion for radiologists. For this research, we utilize publicly available datasets that have been marked by radiologists into two-classes (COVID-19 and non-COVID-19). We address the class imbalance problem associated with the training dataset by proposing a novel transfer-to-transfer learning approach, where we break a highly imbalanced training dataset into a group of balanced mini-sets and …

Polarization-Selective Modulation Of Supercavity Resonances Originating From Bound States In The Continuum, Chan Kyaw, Riad Yahiaoui, Joshua A. Burrow, Viet Tran, Kyron Keelen, Wesley Sims, Eddie C. Red, Willie S. Rockward, Mikkel A. Thomas, Andrew M. Sarangan, Imad Agha, Thomas A. Searles

Electro-Optics and Photonics Faculty Publications

Bound states in the continuum (BICs) are widely studied for their ability to confine light, produce sharp resonances for sensing applications and serve as avenues for lasing action with topological characteristics. Primarily, the formation of BICs in periodic photonic band gap structures are driven by symmetry incompatibility; structural manipulation or variation of incidence angle from incoming light. In this work, we report two modalities for driving the formation of BICs in terahertz metasurfaces. At normal incidence, we experimentally confirm polarization driven symmetry-protected BICs by the variation of the linear polarization state of light. In addition, we demonstrate through strong coupling …

Unhinging The Machismo Binary Through A Third Space Lens: Reframing Latinx Males Postsecondary Academic Decision-Making, Matthew A. Witenstein, Alejandro Cervantes

Educational Leadership Faculty Publications

This critical and conceptual analysis problematizes the machismo binary and situates it in a third space framework. It explores Latinx males’ higher education experiences and how machismo influences academic decision-making. Situating Latinx males’ college-going in the third space provides a more nuanced portrayal of their academic decision-making across diverse postsecondary settings. In doing so, the Latinx Gender Identity Development Model for Latinx Males in the Third Space is proposed and connects machismo with other domains such as marianismo, caballerismo and familismo. The proposed framework is illustrated by applying it to Latinx males across critical dimensions that impact their decision-making in …

The 2019 P-Mig Student Survey Report And Capturing The Undergraduate Perspective Of Physiology Programming, Jennifer Rogers, Jenny L. Mcfarland, Claudia I. Stanescu, Patrick L. Crosswhite, Anne R. Crecelius

Health and Sport Science Faculty Publications

The aim of the 2019 Student Survey was to inform the Physiology Majors Interest Group (PMIG) of characteristics of undergraduates enrolled in physiology courses or degree programs from across the United States, to be used as one input source for development of program-level guidelines. 1389 participants from seven universities completed the 2019 P-MIG Student Survey. 37% reported enrollment in a physiology/human physiology major; allied health related programs were the second most common (24%). 61% of respondents reported attending a community college, the majority of whom enrolled in one or more courses at a community college while in high school (44%). …

The Role Of Culture In The Transfer Of Training, Corinne Brion

Educational Leadership Faculty Publications

Organizations interested in raising their performance and results spend large sums of money on training their employees, but unless the resultant learning is transferred to the work situation, that investment will not yield a return. This study's initial premise is that national cultures may play a part in the transfer process. The study’s purpose is to identify national cultural factors which may influence training and learning transfer. Leadership trainings among school leaders in Ghana and Burkina Faso, West Africa were observed and recorded using Hofstede, Hofstede, and Minkov’s (2010) Six Cultural Dimensions model as a framework of analysis. Some cultural …

A Two-Clone Approach To Study Signaling Interactions Among Neuronal Cells In A Pre-Clinical Alzheimer’S Disease Model, Catherine J. Yeates, Ankita Sarkar, Prajakta Deshpande, Madhuri Kango-Singh, Amit Singh

Biology Faculty Publications

To understand the progression of Alzheimer's disease, studies often rely on ectopic expression of amyloid-beta 42 (Aβ42) throughout an entire tissue. Uniform ectopic expression of Aβ42 may obscure cell-cell interactions that contribute to the progression of the disease. We developed a two-clone system to study the signaling cross talk between GFP-labeled clones of Aβ42-expressing neurons and wild-type neurons simultaneously generated from the same progenitor cell by a single recombination event. Surprisingly, wild-type clones are reduced in size as compared with Aβ42-producing clones. We found that wild-type cells are eliminated by the induction of cell death. Furthermore, aberrant activation of c-Jun-N-terminal …

Does The Presence Of Multiple Β-Lactamases In Gram-Negative Bacilli Impact The Results Of Antimicrobial Susceptibility Tests And Extended-Spectrum Β-Lactamase And Carbapenemase Confirmation Methods?, Fred C. Tenover, Caitlin M. Dela Cruz, Scott Dewell, Victoria M. Le, Isabella A. Tickler

Biology Faculty Publications

Objectives: Many multidrug-resistant Gram-negative bacilli (MDR-GNB) harbour multiple β-lactamases. The aim of this study was to assess the impact of multiple β-lactamase carriage on the accuracy of susceptibility tests and extended-spectrum β-lactamase (ESBL) and carbapenemase confirmation methods.

Methods: A total of 50 MDR-GNB, of which 29 carried multiple β-lactamases, underwent broth microdilution (BMD) and disk diffusion (DD) testing as well as confirmation tests for ESBLs and carbapenemases. Whole-genome sequencing (WGS) was used for β-lactamase gene identification.

Results: Categorical agreement of BMD and DD testing results ranged from 86.5 to 97.7% for 10 β-lactam agents. BMD and DD algorithms for ESBL …

Hvac Zoning Control Systems And Building Energy Management, Vibhu Sharma, Vrushank Mistry

Mechanical and Aerospace Engineering Graduate Student Publications

This research paper delves into the intricate integration of HVAC Zoning Control Systems with Building Energy Management (BEM), unveiling a symbiotic relationship poised to revolutionize the dynamics of modern building environments. HVAC zoning, an innovative approach to climate control, permits precise regulation of temperatures in distinct zones within a structure, offering unprecedented customization. Simultaneously, BEM, a strategic framework, is dedicated to orchestrating holistic energy consumption optimization. This study navigates the intersection of HVAC zoning and BEM, meticulously exploring their synergies, applications, and the potential transformative impacts on energy efficiency, occupant comfort, and operational cost savings within the built environment. The …
