Predicting On-Ice Performance Using Off-Ice Anaerobic Testing in Ice Hockey Ian Malbec This study was to help understand and see any correlation between on-ice performance and anaerobic capacity testing. The PSU Women's Club Ice Hockey volunteered to help (n=23) perform the tests and to be involved in the study. Using a Monarch Wingate test we measured their anaerobic power and capacity and then gave them a workout plan for the season to see if there was any positive increase in those measures. Two tests were administered. Christopher Bopp 199 Alumni Hall, HUB-Robeson Center
Predicting Political Stance of News Articles using Machine Learning Elijah Reber In this project, we look at how effective a support vector machine (SVM) is in classifying the political bias of a news article. A set of 15,000 articles was obtained and the bias was gauged using crowd-sourced information. Articles were classified with a bias rating of "Far Right", "Right", "Unbiased", "Left" or "Far Left". The SVM performed well amongst the labels, with an average of 82% correct and slightly better Far Right classification results. Dongwon Lee 321 Heritage Hall, HUB-Robeson Center
Preliminary evaluation of cryoablation as autovaccination for breast cancer Zachary Aukers Triple-negative breast cancer (TNBC) is an aggressive form of breast cancer with few treatment options. Therefore, we tested if cryoablation of TNBC can induce immune responses using a mouse model. Cryoablation triggered robust increases of Th1 and Th2 cytokines in both spleen and lymph nodes. These immune responses might explain why animals treated with cryoablation, though having circulating tumor cells at the time of treatment, had fewer metastatic foci compared to other forms of treatment.

Psychosocial risk factors of food insecurity in Puerto Rican Adults from baseline to 5-year follow up Dixin Xie

Food insecurity(FI) is prevalent among Puerto Rican(PR) adults. In this study, we did a secondary data analysis on the Boston Puerto Rican Health Study Cohort(n=923). We aimed to explore the longitudinal association between several psychosocial factors (Acculturation, depression, stress, social and community support, and life events) and FI status over 5 years. We found depression and stress may increase the risk of FI among PR adults.

Puppy raiser experience and early behavior patterns of service dogs in training: A pilot study Katrina Heckman Service dogs are widely used in the United States to assist people living with a wide array of disabilities. The objective of this project is to determine the effect of raiser experience on puppy behavior. This study showed that the top four behavior issues seen were jumping (23.5%), mouthing (21.7%), chewing (18.0%), and housesoiling (17.9%). The results may be used by the service dog organizations to equip their raisers to handle these issues with training. Nancy Dreschel 272 Alumni Hall, HUB-Robeson Center
Purification and crystallization of the Staphylococcus aureus heme-regulating proteins HemA and HssR Donovan Brown Staphylococcus aureus is a highly virulent bacterium that infects over 1 million people each year, with the ability to colonize and infect every organ in the human body. Specifically, we know S. aureus protein HemA controls synthesis of heme, while protein HssR regulates the export of heme when it reaches toxic cellular levels. Towards the goal of understanding HemA and HssR's functions, we applied protein expression, purification, and crystallization techniques to solve both molecules' structures.

Quantitation of DNA Collected on microFLOQ™ Direct Collection Device Nina Matulis Items touched and left at a crime scene, often contain minute amounts of body fluids. The cells from these objects can be collected by various methods. Using the microFLOQ(tm) direct collection device, which contains a swab with lysing reagent at the tip, epithelial cells from various touched evidence were collected, and extracted. The extracted DNA was quantified using Real Time PCR. The results indicated that STR DNA profiles can be successfully generated from touched evidence. Reena Roy 278 Alumni Hall, HUB-Robeson Center
Quorum Sensing Between Vibrio fischeri Populations within the Squid Light Organ Andrew Murtha Microbes impact the development and physiology of animals. Quorum sensing describes a signaling mechanism that coordinates behaviors among bacterial cells. How quorum sensing functions within a host remains poorly understood. Vibrio fischeri is a bacterium that colonizes the light organ of the Hawaiian bobtail squid, where the resulting populations produce bioluminescence via quorum sensing. I found that separate populations of dark V. fischeri mutants communicate by quorum sensing within the host to produce luminescence. Tim Miyashiro 196 Alumni Hall, HUB-Robeson Center
Reality in Unity Kadijah Nurudeen Creating the real word in virtual reality has been a challenge for a long time. NVIDIA has managed to make a very good representation of fluids and its associated components that can be integrated into Unity. However, mastering the physics of aerodynamics and implementing it into a computer platform has not been properly accomplished yet. When completed, this will pose an adequate environment to test the performance of the planes being made in the lab. Conrad Tucker 226 Alumni Hall, HUB-Robeson Center

Recovery and regrowth after sampling by deep water octocorals in the Gulf of Mexico Lena Bullock Minimizing the effects of sampling is important for responsible scientific research, as well as for the preservation of deep water coral communities. However, in many cases deep sea corals are still being sampled without special tools resulting in unnecessary damage to the corals and in some cases even inadvertent destruction of entire colonies. In this study, we examined growth of Callogorgia delta after the removal of portions of the colonies using a specially designed cutter. Charles Fisher 146 Alumni Hall, HUB-Robeson Center
Recruitment and survival of gray catbirds and white-throated sparrows calculated from age ratios Wendy Davis From 2011 to present, the Penn State Arboretum has been hosting a bird-banding program under the direction of Mr. Nick Kerlin. Two of the most common birds captured are gray catbirds and white-throated sparrows. This stud compares the number of juvenile and adult birds captured each year to assess how the populations of these species have changed through time. Results indicate there are consistently relatively more juveniles in the fall than in the spring. Margaret Brittingham 137 Alumni Hall, HUB-Robeson Center
Release from proactive interference? Memory for words in segmentally similar contexts Daniel Wheeler Interference effects on memory for words in a Brown-Peterson paradigm as a function of segmental overlap in terms of the presence of orthographic and phonological constituents were investigated. Results are interpreted within a working memory model assuming observed improvement in recall reflects a decrement in interference. Steven Berg 167 Alumni Hall, HUB-Robeson Center
Representation and Dissemination of Unconventional Architecture through Unconventional Mediums Yumih Chang This project aimed to explore and develop a new approach to representing unconventional architecture using unconventional mediums.

Screening the Human Dopamine Transporter gene (DAT1) for Taq1 site variability Georgia Bastos The region around exon 7 of the DAT1 gene was screened for Taq1 sites to determine if distinct individuals have significantly different genotypes. Regions were amplified by PCR and cut with restriction enzyme; gel electrophoresis was done to asses variability by comparing fragment. length. Results point to the conclusion that Taq1 sites are not responsible for individual variability within the region around exon 7 of DAT1 gene. David Vandenbergh 172 Alumni Hall, HUB-Robeson Center
Searches for Dark Matter Using the LZ Experiment Joshua Norfolk I am working on the LUX-ZEPLIN project (LZ), which is an international experiment aiming to detect dark matter particles using a 10-tonnes liquid xenon detector. I worked on the assembly of a test cryostat, which is crucial for the commissioning of the cryogenics and xenon circulation systems of the LZ experiment. I am also performing studies of the sensitivity of LZ to dark matter particles, using profile likelihood ratio techniques. Carmen Carmona 162 Alumni Hall, HUB-Robeson Center
Searching for the Target of KKL-896 Isabel Hunsberger Bacteria continuously become resistant to current antibiotics; thus, scientists must continuously synthesize new antibiotics. KKL-896 inhibits a bacterial pathway called trans-translation; however, its molecular target is unknown. To discover the target, resistant mutants were created and whole-genome sequencing of these mutants led to five genes of interest. Each gene has been studied in hopes of defining KKL-896's target. By knowing KKL-896's target, drug development may advance, ultimately unveiling a new way to combat tuberculosis. Kenneth Keiler 222 Alumni Hall, HUB-Robeson Center
Seasonal Influences on Active Transport James Burton Kauffman

Active transport (AT, walking or biking) to, from, and on campus can help students be active and benefit their health. This study examined how AT varied based on the time during the semester and season. Students reported demographics, residence, distance from campus, and AT behaviors. In fall semester there was a significant decline in AT. By contrast, AT remained unchanged in spring semester. Findings indicate that season influences the college students' AT behaviors.

Self-Regulation does not Moderate the Relationship between Traumatic Life Events and Student Academic Performance Samantha Dawn Long

Traumatic life events can have serious consequences on college students and their education. The current study investigated the relationship between students' self-regulation and how it may predict perseverance to succeed in college, despite traumatic life events. There was no significant correlation between traumatic life events and GPA. High self-regulators had marginally significant higher GPAs, but there was no support for the hypothesis that self-regulation moderates the relationship between traumatic life events and GPA.

Sensor development for chronic measurement of brain oxygenation in epilepsy. Santiago Lopez We observe both seizure and spreading depression events in animal models of epilepsy. In this field, an unresolved question is the role of tissue oxygenation on the brain's susceptibility to these events. Thereby, my work has been focused on fabricating customized electrochemical sensors to monitor brain oxygenation in long-term chronic recordings. Bruce Gluckman 223 Alumni Hall, HUB-Robeson Center
Severe Somatic Bottleneck in Mitochondrial DNA of Human Hair Alison Barrett Heteroplasmy is the presence of a genetically heterogeneous population of mitochondrial DNA within the same individual, tissue, or cell, which can result from de novo mutations or from inheritance of variants via the maternal lineage. We analyzed heteroplasmy allele frequency at specific sites in human hairs and estimated the somatic bottleneck using population genetics modeling. These findings have important implications in forensic investigations and for our understanding of mtDNA dynamics in the human body. Kateryna Makova 330 Heritage Hall, HUB-Robeson Center
Sexual Scripts and Social Media Use Valeria Mercado As humans, there is an inherent need for relationships. Social media and communication are rapidly changing, consequently affecting these relationships and the psychological perspective of individuals. Having identified a gap in the literature, this research focuses on examining how social media has changed social norms, specifically sexual scripts. Through an online questionnaire, we analyze how age and social media usage correlates to their perceptions on sexuality. Alicia Drais-Parrillo 203 Alumni Hall, HUB-Robeson Center
Sexual Size Dimorphism in the Common House Spider, Parasteatoda tepidariorum Kathryn Bruce This research is an investigation of the mechanisms behind sexual dimorphisms in spiders. Specifically, my aim is to understanding why female spiders are typically larger than their male counterparts by answering the following three questions. 1. When does sexual size dimorphism (SSD) become noticeable in Parasteatoda tepidariorum's (common house spider) development? 2. What are the molecular signals involved in SSD? 3. What is the evolutionary benefit of SSD? Jessica Petko 294 Alumni Hall, HUB-Robeson Center

Sleep as it Relates to Performance Across Three Cognitive Batteries Lauren Gerlin, Dominique Prawl and Terrance Knox

This study examined the performance of two computer-based batteries (CogState and Joggle), and a paper/pencil battery (Neruopsych) as it relates to worse sleep within older black adults (n= 87, females= 68). The computer-based batteries, particularly Joggle, appear to be most sensitive for detecting an association between worse sleep and poor cognitive performance. Results suggest type of cognitive battery administered to older Blacks may influence the ability to detect associations between sleep and cognitive functioning.

Small Molecule Signaling Between Bacterial Populations within a Host Taylor Yount Quorum sensing describes the small molecule signaling mechanism that bacteria use to coordinate population-level behaviors. Bacterial expression of these behaviors can significantly impact the health of their host. The marine bacterium Vibrio fischeri colonizes specific sites in the Hawaiian Squid Euprymna scolopes, forming a mutually beneficial symbiosis where the V. fischeri populations produce bioluminescence through quorum sensing. This symbiosis serves as a model system to study quorum sensing within a host environment. Tim Miyashiro 192 Alumni Hall, HUB-Robeson Center
Small Oligonucleotide Models of the Twister Ribozyme Active Site Show That Tertiary Structure is Necessary for Catalysis Matthew Tracey Since the initial discovery of catalytic RNAs, or ribozymes, various examples such as the twister ribozyme have been discovered. We hypothesized that part of the twister catalytic mechanism could be studied in isolation via RNA hexamers that were shown to cleave at UA or CA motifs, similar to twister. I found that these UA and CA motifs in small hexamers do not possess intrinsic reactivity as originally observed, illustrating the importance of twister's 3D structure.

Spin-Dicke Effect in Inorganic Devices Nathaniel Donaher The Spin-Dicke effect is a phenomenon observed in electrically detected magnetic resonance (EDMR) in organic devices. The EDMR effect involves changing electron spin-states to control a recombination current. In the Spin-Dicke phenomenon, the oscillating field, B1, which causes resonance and changing spin-states, is approximately equal to the quasi-static magnetic field, B0. In these experiments, the EDMR effect under the Spin-Dicke regime was observed in an inorganic semiconductor device (SiC p-n junction) via spin-dependent recombination. Patrick Lenahan 4 Flex
Spontaneous Seizure-Associated Spreading Depolarization Relationship with Heart Rate in a Chronic Rodent Model of Temporal Lobe Epilepsy Carlos Curay Previous studies assumed that Spreading Depression and seizure dynamics were closely associated. This correlation is significant because it supports the framework that Sudden Unexpected Death in Epileptic Patients (SUDEP) is mediated by SD invasion of brainstem. The Gluckman lab has consistently found SD alongside seizures in a tetanus toxin model. Now, the group is looking at EKG data alongside SD data as a potential explanation for SUDEP, which could ultimately lead to new treatment approaches.

Stationary Wave Profiles for Nonlocal Particle Models of Traffic Flow on Rough Roads Jereme Chien We study a nonlocal particle model describing traffic flow on rough roads. Each car adjusts its speed according to the condition over an interval, leading to a system of nonlocal ODEs. We seek stationary wave profiles and show that depending on the case, there exists one, infinitely many, or no profiles. Various numerical simulations are presented. We establish convergence of these profiles to a local particle model and a nonlocal PDE model. Wen Shen 128 Alumni Hall, HUB-Robeson Center
