Application Of Ordinal Regression Models To Acquired Stress Resistance In Wild Strains Of Saccharomyces Cerevisiae, Carson Stacy

Graduate Theses and Dissertations

This thesis explores the application of ordinal regression to the analysis of semi-quantitative growth assays often used when comparing fitness for different strains of the model yeast Saccharomyces cerevisiae. For stress survival assays, yeast stress resistance is measured using an ordered survival score that ranges from 0 (no growth) to 4 (confluent growth). Traditional approaches to analyze this type of data either treats data as a nominal categorical variable or as a continuous numerical variable. These approaches risk loss of information or violation of testing assumptions. In contrast, cumulative logit ordinal regression uses the information contained in the order …

The Ai Input Class: Constitutional Urgency And Fair Licensing In Ai Copyright Class Actions, Xuan-Thao Nguyen, Elizabeth G. Porter

Articles

The humanities have long been under attack; now Big Tech is eating them for breakfast. Artificial Intelligence is undermining the cultural and constitutional values of human creativity; it is also threatening the livelihoods of the creative working class. Because neither Congress nor regulators can keep pace with AI’s pace of change, class actions have stepped into the breach. In the first wave of such litigation, authors and artists in courts on both coasts claim that AI companies violate intellectual property law when they “train” their systems on copyrighted works.

This Article analyzes what we call “input” AI claims—that is, proposed …

Computationally Guided Liquid Crystal-Based Competitive Binding Sensing Platform For Optical Detection Of Spike Protein, Homa Ghaiedi, Shubham Pandey, Sophia Ezendu, Tibor Szilvasi, Karthik Nayani

Chemical Engineering Faculty Publications and Presentations

A liquid crystal (LC)-based sensing platform for the rapid optical detection of SARS-CoV-2 ' s spike protein's receptor binding domain (RBD) domain is introduced. This platform utilizes a thermotropic LC, hosted on metal-cation decorated substrates, onto which the spike protein can competitively bind. Density functional theory (DFT) calculations guide the experiments that reveal a homeotropic-to-planar transition in the LCs upon exposure to SARS-CoV-2 spike-decorated yeast, providing a basis for sensitive virus detection. The sensor's reversibility/specificity is confirmed through antibody-induced orientation recovery of the LCs initial orientation. Strikingly, the sensor can detect approximate to 2000 copies of the spike protein per …

Accuracy Of Balance Assessment Metrics Using Wearable Sensors, Brandon Sirof

Anthropology

Balance is a critical part of remaining healthy at all ages. Poor balance can lead to life-changing injury. Balance is typically assessed in a lab using a force-platform (FP), by comparing horizontal movements of the center of mass during trials with eyes open and eyes closed. The goal of this study is to evaluate whether inertial measurement units (IMUs) can be used to accurately measure balance. Simultaneous FP and IMU data were collected for 1 subject for 45s trials with eyes open (EO) and eyes closed (EC). We evaluate whether IMU and FP metrics for COM movement (max accel and …

Using Wearable Sensors For Gait Analysis: Measurement Accuracy For Linear Measurements, Evan Block

Anthropology

Measurement and analysis of human movement are necessary in a broad range of clinical, sports performance, and artistic applications. Historically, motion data were typically collected using optical motion capture systems. However, these systems are expensive and can only be used in lab spaces, which limits the range and speeds of human behavior. More recently, inexpensive, wearable sensors called Inertial Measurement Units (IMUs) have enabled motion measurement in natural settings, but these systems require validation before use. In this study, we evaluate measurement accuracy for linear displacements obtained using Sparkfun OpenLog Artemis IMUs. We conducted a series of tests, moving the …

Comparison Of Femoral Head Loading In Chimpanzees And Humans, Kyra Kalinovsky

Anthropology

Chimpanzees are the closest living relatives of humans, despite this, the species do have very different loading on the epiphysis of the proximal head of the femur. The difference in loading is primarily due to a difference in locomotion. These differences affect the properties of subchondral and trabecular bone properties in the femoral head. Previous studies have shown that chimpanzees have thick and concave trabeculae that create a dense bone structure (Georgiou et al., 2018). These are found mostly on the inferior and central part of the femoral head. In humans, the structure of the trabecular bone volume is less …

Safe Or Not Safe? Perspectives Of Mo Gender-Affirming Care Providers In Response To Anti-Trans Care Legislation, Eric Lei

Women, Gender, and Sexuality Studies Senior Honors Papers

Receiving gender-affirming care is a life-saving intervention for many, yet the current wave of transphobic rhetoric and anti-trans legislation, such as the Missouri (MO) Senate Bill 49 “Save Adolescents From Experimentation” (SAFE) Act, continue to restrict trans individuals from accessing gender-affirming care. Previous literature depicts medical providers as enactors of medical power and authority, producing knowledges of trans subjectivities, constructing and controlling trans bodies, and gatekeeping medical care from trans individuals; however, the changing roles, labor, and acts of resistance trans care providers perform under the recent context of heightened social surveillance and legal restrictions have yet to be documented. …

Student Publications

Low-level light therapy (LLLT), particularly using light-emitting diode (LED) devices, has been an effective and non-surgical option for skin rejuvenation, treating signs of aging such as wrinkles, collagen loss, and pigmentation. Despite promising clinical outcomes, variability in treatment parameters such as wavelength, power density, fluence, and treatment regimens remains a challenge in optimizing the therapy for optimal results. Recent studies, including a prospective, randomized, placebo-controlled, double-blinded, and split-face clinical trial by Lee et al. (2007), have demonstrated significant improvements in wrinkle reduction and skin elasticity using 830 nm and 633 nm LED wavelengths. These findings highlight the importance of wavelength …

Hybrid Dc-Dc Converters For Soft Charging Capacitive Actuators: Modeling, Analysis And Design, Bahlakoana Mabetha

Dartmouth College Ph.D Dissertations

Recent trends in haptics, microrobotics and ultrasound technology have shown an increasing use of piezoelectric and other electrostatic actuators. These actuators are suited for miniaturized applications due to their high power density and favorable scalability at a small size. Their electrical impedance at lower frequency (their typical operating range) is capacitive, therefore, they can be modeled as capacitive loads.

The driving circuits for capacitive actuators need to deliver and recover (bidirectional) dominantly reactive power, unlike typical power electronics converters for resistive loads which deliver (unidirectional) real power to the load. Therefore, the circuits, operation, and optimization required to drive these …

Faculty Journal Articles

Stress superposition is one of the strategies used in metal deformation processes to increase the material formability, decrease the required forming forces, and create highly customized components. To investigate the effects of tensile and compressive stresses superposed to the single point incremental forming (SPIF) process, experiments and numerical simulations were conducted for a stainless steel 304 (SS304) truncated square pyramid geometry. Tensile stresses were superposed in-plane on the specimen blank by a custom hydraulic frame, and compressive stresses were incorporated via a polyurethane die. Identified parameters for a martensitic transformation kinetics model for SS304 were used in a two-step finite …

Cafe: Improved Federated Data Imputation By Leveraging Missing Data Heterogeneity

Faculty, Staff and Student Publications

Federated learning (FL), a decentralized machine learning approach, offers great performance while alleviating autonomy and confidentiality concerns. Despite FL's popularity, how to deal with missing values in a federated manner is not well understood. In this work, we initiate a study of federated imputation of missing values, particularly in complex scenarios, where missing data heterogeneity exists and the state-of-the-art (SOTA) approaches for federated imputation suffer from significant loss in imputation quality. We propose Cafe, a personalized FL approach for missing data imputation. Cafe is inspired from the observation that heterogeneity can induce differences in observable and missing data distribution across …

Direct Synthesis Of Cerium Oxide Nanoparticles In Reducing Sugars: Enhanced Ce3+ Surface Density For Biological Application, Balaashwin Babu, Elayaraja Kolanthai, Craig J. Neal, Samarah V. Harb, Udit Kumar, Yifei Fu, Sudipta Seal

Rowan-Virtua Research Day

Cerium oxide nanoparticles (CNPs) are recognized for their ability to scavenge reactive oxygen species (ROS), making them promising candidates for mitigating oxidative damage in biomedical applications. However, many conventional synthesis methods limit the formation of Ce³⁺ states, which are critical for this antioxidant function. Building upon previous findings that glucose can promote Ce³⁺ formation, this study investigates the broader impact of both reducing (glucose, fructose, galactose) and non-reducing (dextran, sucrose, cyclodextrin) natural sugars on CNP synthesis. CNPs were synthesized in the presence of these sugars, and the surface densities of Ce³⁺ were measured. Results showed that reducing sugars significantly increased …
