Partisan Differences In Risk-Taking In A Simulated Pandemic, Jan K. Woike, Sebastian Hafenbrädl, Patricia Kanngiesser, Ralph Hertwig

School of Psychology

Responses to COVID-19 in the United States were split along partisan political lines throughout the pandemic. People on the political left tended to take the medical threat more seriously and were more likely to adopt preventive health behaviors than those on the political right, resulting in clear differences in state-level policies and health consequences. Here, we examine the origins of these differences, investigating whether they are based on interindividual differences or in party dynamics. Two groups of participants (N=819), who had voted either for Donald Trump or Hillary Clinton in 2016, played the Transmission Game. Players made repeated decisions in …

An Integrated Tracking Technique For Underwater Navigation Using Acoustic And Imu Measurements, Mainul Islam Chowdhury, Quoc Viet Phung, Iftekhar Ahmed, Daryoush Habibi

Research outputs 2022 to 2026

Accurate navigation is essential for underwater vehicles like AUVs, which often operate in deep or remote areas. However, complex ocean dynamics, cumulative inertial-measurement unit (IMU) drift, and diverse noise sources often result in erratic and unreliable position estimates. To overcome these challenges, we proposed a method that combines underwater acoustic signals with onboard motion sensor data to improve the underwater position tracking system. The proposed system uses a long baseline (LBL) acoustic array of surface buoys to capture the Time-difference-of-Arrival (TDoA) of a multi-pulse beacon. We extract arrival times using a superimposed-envelope-spectrum (SES) detector, which exploits the beacon’s periodic structure …

A Review Of Reproductive Cycling In Batoid Dentition Morphology With New Data On Two Dasyatid Stingrays From The Western North Atlantic, Lacey Adamik

Undergraduate Student Symposium

Elasmobranchs continuously replace their teeth throughout their lifespan, allowing changes in tooth morphology associated with feeding and reproduction to occur. In many batoid species, males will bite females during pre-copulatory behavior, placing male dentition under selective pressure to meet the demands of both diet and grasping of females. Previous research has documented sexual dimorphism and seasonal dentition changes in several species of batoids, suggesting that this phenomenon is widespread. Much of this research is observation-based, and quantitative studies of dentition are limited, particularly in pelagic species. Pelagic Stingray (Pteroplatytrygon violacea) specimens were previously collected by commercial fishermen, and …

Investigating The Structural And Functional Roles Of Transcriptionally Active Rice Transposons, Eimaan Admad

Undergraduate Student Symposium

Transposable elements (TEs) are crucial contributors to genome dynamics, evolution, gene structure, and regulation of gene expression. Once considered "junk DNA," TEs are now recognized for their significant roles in genome function and organization. TEs are epigenetically regulated through chromatin modifications, genomic imprinting, and the production of small RNAs and long non-coding RNAs (lncRNAs), which in turn can influence gene expression. Despite a wealth of data from sequencing projects advancing TE research, their large size—often exceeding the read lengths of many sequencing platforms—has limited comprehensive analysis. Moreover, the high copy number and sequence similarity (often >80%) within TE families can …
