Department of Biomedical and Translational Sciences Faculty Publications

Every heartbeat depends on cyclical contraction-relaxation produced by the interactions between myosin-containing thick and actin-based thin filaments (TFs) arranged into a crystalline-like lattice in the cardiac sarcomere. Therefore, the maintenance of thin filament length is crucial for myocardium function. The thin filament is comprised of an actin backbone, the regulatory troponin complex and tropomyosin that controls interactions between thick and thin filaments. Thin filament length is controlled by the tropomodulin family of proteins; tropomodulin caps pointed ends of thin filaments, and leiomodin (Lmod) promotes elongation of thin filaments by a “leaky-cap” mechanism. The broader distribution of Lmod on the thin …

Are Csr Incidents Truly Bad News?, Chen Chen, John A. Doukas, Rongyao Gloria Zhang Jan 2025

Are Csr Incidents Truly Bad News?, Chen Chen, John A. Doukas, Rongyao Gloria Zhang

Finance Faculty Publications

We revisit whether disclosures of negative Corporate Social Responsibility (CSR) incidents adversely affect firms' stock prices. While univariate tests reveal significant negative abnormal returns around incident announcements, the effect disappears once firm characteristics, industry, and time‐fixed effects are controlled for. We find no robust evidence that CSR incidents or firms' Environmental, Social, and Governance (ESG) commitments influence stock price reactions on the event day or across broader windows. These results suggest that previously documented negative market responses may be attributable to endogeneity. Our baseline results are consistent with informed trading behavior: short‐sellers do not increase activity in incident‐related stocks relative …

Facilitation Of Chemotherapy Efficacy Through Targeted Drug Delivery In Lung Cancer Cells Via Ultrasound And Implications On Health Interventions, Ibrahim Nasim

Honors Undergraduate Theses

Lung Cancer (small cell and non-small cell) is the leading cause of cancer death in the US, accounting for about 20% of all cancer deaths. Paclitaxel (PTX) is a chemotherapeutic agent commonly used to treat lung cancer. It works by slowing and stopping cancer growth by stiffening microtubules within cells, promoting mitotic halt and cell death. Carboplatin (CP) is another agent given to lung cancer patients containing platinum and works via direct damage of oncolytic DNA. The exact mechanism of how PTX and CP cause cell death is still an under-studied area. This thesis aims to provide insight into how …

The Intersection Of Autism Spectrum Disorder And Mental Health: A Focus On College Students, Sudeepta Matha

Honors Undergraduate Theses

Rising prevalence rates of autism spectrum disorder (ASD), changes in diagnostic criteria, and increased public awareness have all contributed to the growing population of college students with ASD. However, many individuals - commonly referred to as the “lost generation” - go undiagnosed, due to experiencing negative interactions with mental health professionals. As a result, these individuals are not given the proper support and interventions required for a successful transition into adulthood, and often face heightened social isolation, academic problems, mental health challenges compared to their neurotypical peers. A combination of these factors can lead to increased suicidal ideation (SI) and …


The Gender Wage Gap In An Online Labor Market: The Cost Of Interruptions, Abi Adams, Kotaro Hara, Kristy Milland, Chris Callison-Burch Jan 2025

The Gender Wage Gap In An Online Labor Market: The Cost Of Interruptions, Abi Adams, Kotaro Hara, Kristy Milland, Chris Callison-Burch

Research Collection School Of Computing and Information Systems

This paper analyses gender differences in working patterns and wages on Amazon Mechanical Turk, a popular online labour platform. Using information on 2 million tasks, we find no gender differences in task selection nor experience. Nonetheless, women earn 20% less per hour on average. Gender differences in working patterns are a significant driver of this wage gap. Women are more likely to interrupt their working time on the platform with consequences for their task completion speed. A follow-up survey shows that the gender differences in working patterns and hourly wages are concentrated amongst workers with children.


Synthesizing Multi-Person And Rare Pose Images For Human Pose Estimation, Liuqing Zhao, Zichen Tian, Zou Peng, Richang Hong, Qianru Sun Jan 2025

Synthesizing Multi-Person And Rare Pose Images For Human Pose Estimation, Liuqing Zhao, Zichen Tian, Zou Peng, Richang Hong, Qianru Sun

Research Collection School Of Computing and Information Systems

Human pose estimation (HPE) models underperform in recognizing rare poses because they suffer from data imbalance problems (i.e., there are few image samples for rare poses) in their training datasets. From a data perspective, the most intuitive solution is to synthesize data for rare poses. Specifically, the rule-based methods apply manual manipulations (such as Cutout and GridMask) to the existing data, so the limited diversity of the data constrains the model. An alternative method is to learn the underlying data distribution via deep generative models (such as ControlNet and HumanSD) and then sample “new data” from the distribution. This works …
