Twist And Snout: Head And Body Morphologies Determine Feeding Kinematics In Substrate-Biting Fishes, Tal Perevolotsky, Jacob M. Brotman-Krass, Yarden Ratner, Yael Avigad, Adam P. Summers, Cassandra M. Donatelli, Roi Holzman

Engineering Faculty Articles and Research

Synopsis

Across teleosts, feeding by biting substrate-attached prey has evolved multiple times and is associated with convergent morphologies that include a deep body and an elongated, tapered head. However, the functional role of these morphologies in substrate-biting fish is not established. Here, we tested the hypothesis that these morphologies function as control surfaces that affect feeding kinematics during biting. To test this hypothesis, we used simplified physical models of substrate-biting reef fish and examined the role of head, body, and fin morphology in determining feeding kinematics that facilitate the removal of substrate-attached prey. Models simulated the swift lateral movement of …

Attitudes Toward Seeking Mental Health Services Among Young African American Same-Sex-Oriented Men, Anthony Earl Fox

Walden Dissertations and Doctoral Studies

In 2018 suicide was the second leading cause of death for young people between the ages of 15 and 24 (CDC, 2018). Suicide and other factors like HIV, depression, and oppression may serve as barriers to seeking counseling among African American same-sex-oriented men ages 18-26. Due to a previous gap in the literature regarding barriers to seeking counseling, this study may support counselors in finding ways to address the disparity in counseling utilization among this population. Grounded in queer and social identity theories, the purpose of this quantitative study was to examine if adverse childhood experiences, current civic unrest, HIV, …

Towards Scalable Taxi Demand Prediction, Yifei Shen

Lingnan Theses (MPhil & PhD)

Accurate taxi demand prediction is essential for optimizing urban mobility systems across varying spatial-temporal resolutions and data conditions. Scalable taxi demand prediction refers to the capability of forecasting models to adapt to different granularities of spatial and temporal data while maintaining prediction accuracy, a critical requirement for practical urban applications ranging from fleet management to transportation planning. However, two fundamental challenges impede this scalability: data sparsity and multi-resolution forecasting requirements. Data sparsity, particularly pronounced in high-resolution predictions where numerous regions exhibit minimal activity, significantly compromises model performance. Concurrently, different urban applications necessitate predictions at varying temporal and spatial granularities, requiring …

Stuart, Ji Li, Rui Hou, Peiwen Liu, Shelby Margolius, Claire Kim, Yu Suk Choi, Edward R. Bastow, Dianne J. Beveridge, Lisa Spalding, Ziyi Li, Florent Ginhoux, Pierce Chow, Michael Phillips, Andrew D. Redfern, George C. Yeoh, Alistair Forrest, Andrew J. Woo, Ankur Sharma, Jacob George, Geoffrey Mccaughan, Peter Leedman

Research outputs 2022 to 2026

Resistance to multi-tyrosine kinase inhibitors (TKI) is a major clinical concern in advanced hepatocellular carcinoma (HCC). Herein, we aimed to uncover the mechanisms underlying pan-TKI resistance and to identify potential therapeutic targets. We used multiple TKI-resistant HCC cell lines to identify caveolin-1 (CAV1) as a key driver of therapeutic resistance. CAV1 downregulation induced apoptosis, inhibited metastasis and restored TKI sensitivity in both inherent and acquired TKI-resistant HCC cells. Mechanistically, in acquired TKI-resistant cells aberrant CAV1/STAT3/P70S6K signalling is required for their survival, motility, and invasiveness. CAV1 inhibition reduced expression of dormancy regulators E-cadherin, RAC1 and p21, enhanced cancer stemness markers, and …

The Impact Of Teaching Multiple Responses On Resurgence Of Target Behavior And Persistence Of Alternative Responding., Brittany H. Loder-Lafferty, Amanda N. Zangrillo, Alexandra M. Cicero, Cynthia P. Livingston, Jessica P. Tran, Mark Connelly

Manuscripts, Articles, Book Chapters and Other Papers

This study evaluated the effects of teaching multiple alternative responses on the resurgence of a target response and the persistence of an alternative response in an applied setting. Using a between-participants design, we examined how teaching multiple alternative responses impacted resurgence and persistence upon exposure to extinction. Additionally, we investigated the role of preference in response allocation and shifts in participant preference following extinction. Results indicated resurgence across both conditions, with no consistent difference in severity between single and multiple alternative response conditions. However, within-session analyses revealed greater persistence of the alternative response for participants taught multiple alternative responses, suggesting …

U-Rich Elements Drive Pervasive Cryptic Splicing In 3' Utr Massively Parallel Reporter Assays, Khoa Dao, Courtney F Jungers, Sergej Djuranovic, Anthony M Mustoe

2020-Current year OA Pubs

Untranslated RNA sequences play essential roles in orchestrating gene expression. However, the sequence codes and mechanisms underpinning post-transcriptional regulation remain incompletely understood. Here, we revisit the finding from a prior massively parallel reporter assay (MPRA) that AU-rich elements in 3' untranslated regions (3' UTRs) can drive upregulation or downregulation of mRNA expression depending on 3' UTR context. We unexpectedly discover that this variable regulation arises from widespread cryptic splicing, predominately from an unannotated splice donor in the coding sequence of GFP to diverse acceptor sites in reporter 3' UTRs. Splicing is activated by U-rich sequences, which function as potent position-dependent …
