Vertical Gan Diode Bv Maximization Through Rapid Tcad Simulation And Ml-Enabled Surrogate Model, Albert Lu, Jordan Marshall, Yifan Wang, Ming Xiao, Yuhao Zhang, Hiu Yung Wong

Faculty Research, Scholarly, and Creative Activity

In this paper, two methodologies are used to speed up the maximization of the breakdown voltage (BV) of a vertical GaN diode that has a theoretical maximum BV of ∼ 2100 V. Firstly, we demonstrated a 5X faster accurate simulation method in Technology Computer-Aided-Design (TCAD). This allows us to find 50 % more numbers of high BV (>1400 V) designs at a given simulation time. Secondly, a machine learning (ML) model is developed using TCAD-generated data and used as a surrogate model for differential evolution optimization. It can inversely design an out-of-the-training-range structure with BV as high as 1887 …

Best Practices In Disaster Public Communications: Evacuation Alerting And Social Media, Frannie Edwards, Kaikai Liu, Amanda Lee Hughes, Jerry Zeyo Gao, Dan Goodrich, Alan Barner, Robert Herrera

Mineta Transportation Institute

This research project examines the current state of the practice for disaster public communication, the distrust of government, the training available to public information officers, and the literature available to guide the design of effective public outreach messaging, especially for rapid on-set events. Growing distrust in government had led to lack of public confidence in public agency messaging during emergencies, yet public agency public information officers are using multiple pathways, including both traditional and social media resources, to try to reach impacted communities effectively. The introduction explains the development of wildfire events in the West and their context. A literature …

Healthcare Mistreatment, State-Level Policy Protections, And Healthcare Avoidance Among Gender Minority People, Kristen D. Clark, Sean Luong, Mitchell R. Lunn, Elena Flowers, Esmaeil Bahalkeh, Micah E. Lubensky, Matthew R. Capriotti, Juno Obedin-Maliver, Annesa Flentje

Faculty Research, Scholarly, and Creative Activity

Introduction: This study examined whether past experiences of mistreatment in healthcare were associated with greater healthcare avoidance due to anticipated mistreatment among gender minority (GM) people. We evaluated whether state-level healthcare policy protections moderated this relationship. Methods: Data from the 2018 Annual Questionnaire of The PRIDE Study, a national longitudinal study on sexual and gender minority people’s health, were used in these analyses. Logistic regression modeling tested relationships between lifetime healthcare mistreatment due to gender identity or expression and past-year healthcare avoidance due to anticipated mistreatment among GM participants. Interactions between lifetime healthcare mistreatment and state-level healthcare policy protections and …

Qualitatively Exploring The Impact Of A Relationship-Centered Communication Skills Training Program In Improving Patient Perceptions Of Care, Marie C. Haverfield, Robert Victor, Brenda Flores, Jonathan Altamirano, Magali Fassiotto, Merisa Kline, Barbette Weimer-Elder

Faculty Research, Scholarly, and Creative Activity

Objective: To explore qualitative patient experience comments before and after a relationship-centered communication skills training to understand patient experience, program impact, and opportunities for improvement. Methods: Qualitative patient experience evaluation data was captured from January 2016 to December 2018 for 483 health care clinicians who participated in the skills training. A random sampling of available open-ended patient comments (N = 33,223) were selected pre-training (n = 668) and post-training (n = 566). Comments were coded for valence (negative/neutral/positive), generality versus specificity, and based on 12 communication behaviors reflective of training objectives. Results: No significant difference was found in the valence …

Leaving More Than Footprints: Anthropogenic Nutrient Subsidies To A Protected Area, A. S. Guerra, A. Bui, M. Klope, D. A. Orr, S. A. Shaffer, H. S. Young

Faculty Research, Scholarly, and Creative Activity

Mobile animals that traverse ecosystem boundaries can fundamentally reshape environments by providing critical nutrient and energy inputs to the ecosystems they inhabit. In particular, aggregations of seabirds often transform coastal and island ecosystems through large amounts of nutrient-rich guano deposition. Anthropogenically driven losses of these subsidies can occur through changes in abundance of mobile species, including seabirds, and have been shown to drive whole-scale ecosystem state change on islands. However, even though many species that forage on anthropogenic food sources are highly mobile and may thus play important roles in moving nutrients from urban systems to otherwise conserved ecosystems, the …

Exploring The Microgeography And Typology Of U.S. High-Tech Clusters, Ahoura Zandiatashbar, Shima Hamidi

Faculty Research, Scholarly, and Creative Activity

Despite the principal role of high-tech clusters in local planning practice and research, their location and sectoral typology at the granular level have been rarely studied. This study explores the location of U.S. high-tech clusters at a micro-scale by employing firm-level data sets and spatial statistics and examines their sectoral typology using market concentration indices in 52 large U.S regions. The majority (80 %) of the 627 tech clusters we identify have multiple dominant tech industries or are specialized in professional services. Furthermore, while clusters form the major regional hubs for the high-tech economy, they are home to a very …

Secure Human Action Recognition By Encrypted Neural Network Inference, Miran Kim, Xiaoqian Jiang, Kristin Lauter, Elkhan Ismayilzada, Shayan Shams

Faculty Research, Scholarly, and Creative Activity

Advanced computer vision technology can provide near real-time home monitoring to support “aging in place” by detecting falls and symptoms related to seizures and stroke. Affordable webcams, together with cloud computing services (to run machine learning algorithms), can potentially bring significant social benefits. However, it has not been deployed in practice because of privacy concerns. In this paper, we propose a strategy that uses homomorphic encryption to resolve this dilemma, which guarantees information confidentiality while retaining action detection. Our protocol for secure inference can distinguish falls from activities of daily living with 86.21% sensitivity and 99.14% specificity, with an average …

A Multitask Deep Learning Approach For Pulmonary Embolism Detection And Identification, Xiaotian Ma, Emma C. Ferguson, Xiaoqian Jiang, Sean I. Savitz, Shayan Shams

Faculty Research, Scholarly, and Creative Activity

Pulmonary embolism (PE) is a blood clot traveling to the lungs and is associated with substantial morbidity and mortality. Therefore, rapid diagnoses and treatments are essential. Chest computed tomographic pulmonary angiogram (CTPA) is the gold standard for PE diagnoses. Deep learning can enhance the radiologists’workflow by identifying PE using CTPA, which helps to prioritize important cases and hasten the diagnoses for at-risk patients. In this study, we propose a two-phase multitask learning method that can recognize the presence of PE and its properties such as the position, whether acute or chronic, and the corresponding right-to-left ventricle diameter (RV/LV) ratio, thereby …

Towards The Ionizing Radiation Induced Bond Dissociation Mechanism In Oxygen, Water, Guanine And Dna Fragmentation: A Density Functional Theory Simulation, Santosh Kc, Ramin Abolfath

Faculty Research, Scholarly, and Creative Activity

The radiation-induced damages in bio-molecules are ubiquitous processes in radiotherapy and radio-biology, and critical to space projects. In this study, we present a precise quantification of the fragmentation mechanisms of deoxyribonucleic acid (DNA) and the molecules surrounding DNA such as oxygen and water under non-equilibrium conditions using the first-principle calculations based on density functional theory (DFT). Our results reveal the structural stability of DNA bases and backbone that withstand up to a combined threshold of charge and hydrogen abstraction owing to simultaneously direct and indirect ionization processes. We show the hydrogen contents of the molecules significantly control the stability in …
