Pseudo-Soft-Switching Switched-Capacitor Drive Circuits For Small-Scale Dielectric Actuators, Yanqiao Li

Dartmouth College Ph.D Dissertations

Applications including micro-robotics and haptics have motivated extensive exploration of dielectric actuators due to their high bandwidth and high efficiency at cm and mm scales. To maximize their benefits, dielectric actuators, including piezoelectric and electrostatic actuators, typically require high driving voltages, ranging from 100V to several kV. Generating such high driving voltages presents a challenge for drive circuits, particularly when powered by a small battery. Dielectric actuators are predominantly capacitive in most circumstances, necessitating the drive circuits to deliver and recover reactive energy for efficient operation. In some applications, such as micro-robotics, the drive circuits may need to have a …

The Scintillator Surface Detector Of The Pierre Auger Observatory, A. Abdul Halim, P. Abreu, M. Aglietta, I. Allekotte, K. Almeida Cheminant, A. Almela, B. Fick, K. Nguyen, D. Nitz, Et Al.

Michigan Tech Publications

Data collected so far by the Pierre Auger Observatory have enabled major advances in ultrahigh energy cosmic ray physics and demonstrated that improved determination of masses of primary cosmic-ray particles, preferably on an event-by-event basis, is necessary for understanding their origin and nature. Improvement in primary mass measurements was the main motivation for the upgrade of the Pierre Auger Observatory, called AugerPrime. As part of this upgrade, scintillator detectors are added to the existing water-Cherenkov surface detector stations. By making use of the differences in detector response to the electromagnetic particles and muons between scintillator and water-Cherenkov detectors, the electromagnetic …

Differing Impacts Of Cardiac Implantable Electronic Device Leads On Tricuspid Regurgitation, Sophie A. Leon, Melissa Austin, Nayeem Nasher, Daler Rahimov, Faizaan Siddique, Chitra Parikh, Danial Ahmad, Vakhtang Tchantchaleishvili, Behzad B. Pavri

Division of Cardiology Faculty Papers

BACKGROUND: Placement of cardiac implantable electronic devices (CIED) with leads that traverse the tricuspid valve is thought to contribute to tricuspid regurgitation (TR). However, there are relatively limited data comparing the impact of different CIED lead types on the incidence and progression of TR. This study sought to quantify the change in TR severity following implantation of CIEDs with different lead types.

METHODS: Patient data were collected on individuals with implantable cardioverter defibrillators (ICD), right ventricular-paced pacemakers (RV-PM), and His bundle-paced pacemakers (His-PM) placed by a single provider at a single institution between 2016 and 2019. Patients with extravascular CIED …

Not All Political Ties Are The Same: Firms' Ties To The Government And Pollution, Wen Helena Li, Ilya R. P. Cuypers, Gokhan Ertug, Hari Bapuji, Wei Liu

Research Collection Lee Kong Chian School Of Business

Complementing research on the implications of political ties for firms’ strategic decisions and financial performance, recent studies are increasingly focusing on the environmental consequences of firms’ political connections. We contribute to this stream of work by integrating insights from the literature on political ties and the multifaceted nature of governments to explore how the level of government influences the pollution implications of firms’ political ties. Specifically, we theorize and demonstrate that, in China, firms' achieved political ties with high levels of the government reduce pollution, while such ties with low levels of the government increase it. Furthermore, we examine how …

What Values Best Distinguish The World's Cultures? The Machine Learning-Based Cultural Values Inventory, Abhishek Sheetal, Shilpa Madan, Rui Ling Lee, Krishna Savani

Research Collection Lee Kong Chian School Of Business

Scientists studying culture typically focus on a small number of theoretical constructs, such as individualism–collectivism, when seeking to explain cultural differences in psychological tendencies and behaviors. However, existing theories of culture could have missed out on important constructs that are useful for explaining cross-cultural differences. We used an abductive approach combining prediction and explanation to uncover important cultural values. In the prediction phase, based on 594 attitudes, values, and beliefs included in the World Values Survey, a neural network could classify respondents’ nationalities with 90% accuracy in out-of-sample data. In the explanation phase, a feature importance analysis identified the values …

Issues In Contrasting Conservative And Considered Estimation: A Reply To Bobko Et Al. (2024), Paul R. Sackett, Christopher M. Berry, Filip Lievens, Charlene Zhang

Research Collection Lee Kong Chian School Of Business

Bobko et al. (2024) responded to Sackett et al.'s (2022) compilation of meta-analytic evidence for the validity of a wide variety of measures used as predictors of overall job performance, offering a set of alternative methodological choices which they term “considered estimation” to counter the Sackett et al. approach of “conservative estimation.” Here we offer a rebuttal to Bobko et al. A primary concern is that Bobko et al. apply the label “conservative estimation” to the full range of methodological choices made by Sackett et al. Yet, we clarify the narrow and specific meaning of “conservative estimation,” and note that …

Is R&D Rivalry Slowing The Growth Of Productive Firms?, Yoshiki Ando, James Bessen, Xiupeng Wang

Research Collection School Of Economics

The reallocation of jobs to more productive firms is a substantial component of aggregate productivity growth, yet job reallocation rates have declined substantially in the United States. This paper explores the hypothesis that greater technological rivalry has exacerbated adjustment costs, slowing reallocation. Using microdata at the US Census and estimates of technological rivalry in firm growth regressions, we find that technological rivalry slows firm responses to productivity shocks. Firms do not expand as rapidly in the face of higher obsolescence risk. Estimating counterfactual firm growth from 1997-2018, we find that growing technological rivalry accounts for most of the decline in …

Guest Editorial: Who’S Special Now?, Michael Maihofer Dds

The Journal of the Michigan Dental Association

This editorial discusses a controversial change in Michigan's dental specialty advertising law, which occurred in 2020. Previously, only state-recognized specialists, undergoing rigorous advanced training, could advertise their specialty status. However, a new rule, resulting from an out-of-court settlement, paradoxically allows general dentists not recognized as specialists to advertise as such without following advertising rules. This change is criticized for undermining public protection and creating unethical, misleading situations where general dentists advertise as pediatric dentists, for instance. The Michigan Dental Association (MDA) is actively working to revert this law by supporting House Bills 4593 and 4594 to ensure only recognized specialists …

Staff Matters: Adding Background Checks And Drug Testing To The Hiring Process, Jodi Schafer Sphr, Shrm-Scp

The Journal of the Michigan Dental Association

This article advises dental practices on legally and carefully implementing pre-employment background checks and drug testing. It emphasizes ensuring non-discriminatory practices by consistently applying policies and clearly defining screening criteria. Practices must obtain written applicant authorization and provide notification of Fair Credit Reporting Act (FCRA) rights before conducting checks. When evaluating results, relevance to the job and timing of convictions should be considered, avoiding blanket bans. For drug testing, transparency is key. Given Michigan's recreational marijuana legality, a positive THC test does not automatically indicate impairment, requiring practices to define their approach. Using a reputable third-party provider for both screenings …

The Back Page: Hospital General Dentistry: Needed Now More Than Ever, Tanaya K. Porter Dds, Craig C. Spangler Dds

The Journal of the Michigan Dental Association

This commentary emphasizes the increasing necessity of hospital-based general dentists. Historically, dentists faced challenges for privileges in hospitals, but today they are crucial, especially for neurodivergent adult patients and those with complex chronic illnesses requiring general anesthesia for dental care. Untreated oral issues can lead to severe infections, complicating acute medical conditions and threatening the success of life-saving surgeries like organ transplants. Hospital dentists provide vital pre-surgical evaluation, diagnosis, and follow-up care to prevent dental complications and improve patient quality of life post-surgery. Despite their critical role, the article highlights a concerning trend of fewer hospitals having general dentists on …

Using grounded theory and thematic analysis of 152 qualitative responses drawn from experts in technology, healthcare, government, defense, and education, we coded interview data in ATLAS.ti to surface three interdependent control layers—Strategic Governance Controls, Operational Controls, and Technical Controls—that map closely to the NIST Privacy Framework and …

Mechanoregulation Of Osteogenesis And Adipogenesis Of Human Mesenchymal Stem Cells, Justin Caron

Master's Theses

Bone-related diseases (e.g., osteoporosis) are primarily treated with pharmacologic therapies that often exhibit limited efficacy and substantial side effects. Currently, bone marrow derived mesenchymal stem cells (MSCs) have become one of most important cell options in bone regeneration due to readily available sources, strong proliferation abilities, weak immune rejection responses, and strong osteogenic differentiation potential. While identifying the most effective approach to enhance osteogenic differentiation of MSCs for bone regeneration is challenging, understanding the regulatory mechanisms is crucial for improving therapeutic efficacy. Recent research has focused on developing strategies to enhance osteogenesis, which involve biophysical and biochemical stimulation. Mechanical and …

Individual Noise-Tolerance Profiles And Neural Signal-To-Noise Ratio: Insights Into Predicting Speech-In-Noise Performance And Noise-Reduction Outcomes, Subong Kim, Susan Arzac, Natalie Dokic, Jenn Donnelly, Nicole Genser, Kristen Nortwich, Alexis Rooney

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Background/Objectives: Individuals with similar hearing sensitivity exhibit varying levels of tolerance to background noise, a trait tied to unique individual characteristics that affect their responsiveness to noise reduction (NR) processing in hearing aids. The present study aimed to capture such individual characteristics by employing electrophysiological measures and subjective noise-tolerance profiles, and both were analyzed in relation to speech-in-noise performance and NR outcomes. Methods: From a sample of 42 participants with normal hearing, the neural signal-to-noise ratio (SNR)—a cortical index comparing the amplitude ratio between auditory evoked responses to target speech onset versus noise onset—was calculated, and individual noise-tolerance profiles were …

One Step Closer To Greater Understanding! Does A Correlation Exist Between Fluid Intelligence And Player Rank In League Of Legends?, Evan Miller

Dissertations

Chess, one of the oldest modern games, has long been a model domain for expertise research. In comparison, research on video games has historically been influenced by moral panic. Cycles of moral panic tend to revolve around preconceived notions of threats, held at a societal level (typically by older generations). Politicians, quick to capitalize, then advocate for policy change based upon their constituents’ fears. Concurrent media reports draw further attention to the issue, amplifying the perception of harm. As the panic escalates, pressure is placed on scientific communities to perform confirmatory (not exploratory) research. This fundamentally biased approach to research …

The European energy crisis, driven by geopolitical conflicts, has created a significant supply-demand gap in Europe’s fine chemical sector, necessitating reliance on imports from the United States and China. This quantitative study examined how energy, labor, and logistics costs interacted to shape the cost competitiveness of U.S. and Chinese fine chemical exports to Europe, using a Monte Carlo simulation parameterized with historical data from 2015-2023, to provide a probabilistic forecast of competitive outcomes. The findings revealed that while China holds a 76.55% probability of being the lower-cost supplier, its advantage is characterized by high volatility primarily due to its logistics …

Saliva & Circadian Rhythm In Medical Profiling For Early Disease Prevention, Joseph Lewis

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Circadian rhythms affect almost every biological process from hormone secretion, gene expression, immune regulation, and metabolism. Studies show that disruption to these internal rhythms through irregular sleep, artificial sleep, and irregular sleep can significantly increase risk for chronic disease such as diabetes, cardiovascular disorders, neurodegeneration, and cancer. Saliva presents a viable alternative for capturing biomarkers found through blood or cerebrospinal fluid, offering substantial utility for diagnostic and chronobiological profiling. Saliva contains hormones such as cortisol and melatonin while containing inflammatory markers that fluctuate rhythmically throughout the day. Due to its ease of collection, saliva is well suited for longitudinal monitoring, …
