Processing And Characterization Of Non-Speech Human Sounds -- A Step Towards Automatic Reporting Of Respiratory Disease Symptoms, Sudip Vhaduri, Siva Simhadri, Katherine S. Xiong, Bethany Grace Tennyson

Discovery Undergraduate Interdisciplinary Research Internship

Non-speech human sounds, such as coughing and wheezing are common symptoms of many respiratory diseases, including chronic obstructive pulmonary disease (COPD), asthma, and COVID-19. Thereby, an objective reporting of these symptoms from smartphone microphones can help physicians to monitor and treat patients with different respiratory diseases. However, most often audio recordings from smartphones come with different types of background noises and other non-desired sounds, such as laughing, crying, and snoring. Therefore, it is crucial to first process the raw audio clips to extract desired events, such as coughing and wheezing. In our work, we use the Audacity desktop application to …

Hhl Algorithm On The Honeywell H1 Quantum Computer, Adrik B. Herbert, Eric A. F. Reinhardt

Discovery Undergraduate Interdisciplinary Research Internship

The quantum algorithm for linear systems of equations (HHL algorithm) provides an efficient tool for finding solutions to systems of functions with a large number of variables and low sensitivity to changes in inputs (i.e. low error rates). For complex problems, such as matrix inversion, HHL requires exponentially less computational time as compared with classical computation methods. HHL can be adapted to current quantum computing systems with limited numbers of qubits (quantum computation bits) but a high reusability rate such as the Honeywell H1 quantum computer. Some methods for improving HHL have been proposed through the combination of quantum and …

The Bisection: Still A Reliable Treatment Option Of The First Mandibular Molar: A 3 Years Follow Up Case Report, Rahma Bounaouara, Amel Labidi, Sana Bekri, Sameh Rzigui, Lamia Mansour

International Arab Journal of Dentistry

Conservation of mandibular molar teeth exhibiting furcation involvement and perforation of the pulp floor have always been a challenge. Section of the affected tooth at the furcation zone, and preservation of the mesial and distal roots individually with its crown portion, helps to preserve the tooth structure, alveolar bone and avoids sacrificing a strategic tooth. Therapeutic planning is multidisciplinary. It contains surgical, endodontic and prosthetic phase. Long-term success depends on thorough diagnosis and careful selection of cases.

Miscalibrated: A Search For Better Outcomes In Legal Punishment, Pretrial Systems, And Beyond, Matthew Peters

Lawrence University Honors Projects

The seeds of this project were sown in Harrisburg, Pennsylvania in 2017. Having recently graduated high school, I found myself in a studio apartment. I was enrolled at Harrisburg Area Community College and wanted to devote all my time to school so that I could transfer to a nice university. I had signed a lease and had to come up with rent each month. This resulted in an unfortunate reality: given that I was only a high school graduate, it was nearly impossible for me to command an hourly rate high enough to cover my expenses without working at least …

The Influence Of Blm And The Death Of George Floyd On Medical And Pre-Med Students And Their Views On Institutional Racism, Asia Susko, Jason A. Wasserman

Posters

INTRODUCTION
Racial inequalities present in medical education in a multitude of ways, including basing disease prevalence on majority populations and using images that disproportionately represent white patients. George Floyd’s death was not only a sentinel event of police violence, but underscored broader systemic racism, including medicine’s potential for complicity. This study highlights the perspectives of premedical and medical students in light of George Floyd’s death and the Black Lives Matter movement. Their views help elaborate ways to better support students and staff of color in medical education.

Emergency Department Recidivism Due To Skin Lesions Among The Homeless Population, Kylee Jb Kus, Jason A. Wasserman

Posters

INTRODUCTION
Ample research supports the correlation between homelessness and poor health generally. Individuals experiencing homelessness face a higher risk of dermatological health problems due to exposure and sanitation concerns and comprise a disproportionately large share of emergency department (ED) visits. This study assesses whether and how the interaction between homelessness and dermatological health contributes to ED recidivism.

The Divergence Of Medical Ethics And State Laws Regarding Life Sustaining Treatment, Hannah Vandusen, Jason A. Wasserman

Posters

INTRODUCTION
Research reveals that cardiopulmonary resuscitation (CPR) rarely leads to prolonged survival in patients with chronic illnesses in whom death is expected in the relative near-term. There is strong ethical consensus favoring a physician’s right to refuse to provide CPR when it is physiologically futile or medically inappropriate. State laws governing medical treatment, however, sometimes diverge from this guidance. This study examines laws related to life sustaining treatment, analyzing both physician and surrogate authority in decision making about resuscitation orders in the national context.

An Analysis Of Mitochondrial Distribution Across Neuron Types In C. Elegans, Reggie Joseph

Harriet L Wilkes Honors College Theses 2020 - Present

Parkinson’s disease is known to have a greater impact on dopaminergic neurons when compared with other neurons. Dopaminergic neurons regulate muscle movement and coordination, and mitochondria supply the energy needed for that function in the form of ATP. Along with ATP production, mitochondria play an essential role in various other cell processes, and it is quite plausible that neurons of different functional and neurotransmitter types have different dependencies on mitochondria. To further investigate this possibility, mitochondrial distribution was analyzed in different neuron types in electron micrographs of Caenorhabditis elegans. Mitochondria were longest (1.65±0.12 μm) in cholinergic interneurons, and shortest in …

Do Sponges Niphates Digitalis And N. Erecta Survive A Multi-Year Coral Reef Bleaching Event?, Alexandra Perez

Harriet L Wilkes Honors College Theses 2020 - Present

The 2014-17 El Niño Southern Oscillation (ENSO) created a multi-year thermal anomaly that had a severe global impact on coral reefs; however, it is unknown if all reef organisms were negatively impacted. Previous studies suggest that sponges (phylum Porifera) utilize their regenerative capability to survive stress-inducing conditions; however, it is unknown if they employ this ability to survive multi-year thermal stress. This honors thesis determined if populations of the conspicuous Caribbean sponges, Niphates erecta and Niphates digitalis, were affected by the 2014-17 ENSO event in Florida, Broward County Reefs, and evaluated if sponges utilize their regenerative ability under extreme thermal …

Unraveling The Mysteries Of Undiagnosed Disorders With Drosophila Crispr Mutants, Rishiraj Bandi

Harriet L Wilkes Honors College Theses 2020 - Present

Worldwide, the medical community struggles to identify undiagnosed diseases in nearly 25 million patients per year. Even with advances in medical research, physicians cannot determine the mechanisms by which these disorders progress within patients, resulting in a lack of proper treatment. A recent study identified patients who passed away with symptoms of hypotonia and lactic acidosis while having specific mutations in the mitochondrial enzyme, malate dehydrogenase (MDH2). Yet, little is known about the way in which such disorders arise from MDH2 mutations. Intriguingly, the mutations led to destabilization in hypoxia-inducible factor 1-alpha (HIF-1α). Using the CRISPR-Cas9 gene editing technique, we …

Feature Selectivity Of Hippocampal Ca1 Neurons During Memory Encoding, Aden Eagle

Harriet L Wilkes Honors College Theses 2020 - Present

The hippocampus is central to the formation of episodic memories, or memories of personally-experienced events. Episodic memories, in turn, are crucial for navigation along familiar pathways as they can encode information about both external sensory events and internal understandings of position and behavior. The contributions of individual cells in the hippocampus to episodic memory formation and recall during navigation, however, are not well-understood. We recorded the activity of hippocampal CA1 neurons as mice were trained on a particular navigation task which required running a specified distance on a treadmill and then licking on a lick port. Using gradient-boosted decision trees, …

Ethnic Differences In Obsessive-Compulsive Disorder Symptomatology: Comparing Symptom Profiles Of Asian-American, Caucasian-American, And Hispanic-American Groups, Tristan Stinchcomb

Harriet L Wilkes Honors College Theses 2020 - Present

This study investigated whether there exist variations in the presentation of obsessive-compulsive disorder symptomatology across ethnic boundaries and, if so, what these differences are. Padua Inventory and Disgust Emotion Scale scores were collected from Asian-American, Caucasian, and Hispanic individuals. The results showed that the Asian-American and Hispanic groups both had significantly higher mean obsessive-compulsive symptom and trait disgust scores than the Caucasian group. Additionally, Asian-American obsessive-compulsive total scores were significantly higher than Hispanic scores. This study replicates and extends previous findings by comparing the Padua Inventory scores of these three groups with larger samples, and suggests that the overall severity …

Assessment Of A New Mouse Model For Chronic Fatigue Syndrome: Studies Of The Viral Mimetic Poly I:C On Biochemical Measures Of Brain Inflammation And Serotonin Signaling, Tiffany Zhang

Harriet L Wilkes Honors College Theses 2020 - Present

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating, multisystem disease characterized by severe fatigue without medical explanation. Due to the complexity of the disease, treatments only partially alleviate symptoms and currently there is no cure. To develop more effective treatments and better understand its etiology, valid preclinical models need to be developed. Evidence suggests infection and serotonin homeostasis plays a role in the development of ME/CFS. Therefore, I aimed to examine whether a viral mimetic (Poly I:C) triggers long-term fatigue behavior and neuroinflammation in a mouse model. C57 and CD1 male mice were treated with Poly I:C and only CD1 …

Competition And Labour Law In Canada: The Contestable Margins Of Legal Toleration, Eric Tucker

Articles & Book Chapters

In Canada, as elsewhere, the norms of capitalist legality include an aversion to permitting collective action by sellers of commodities to increase their price. Labour law, however, is built on the norm of freedom of association and the right of commodified workers to combine for the purpose of improving the terms of their labour contracts. This gives rise to a recurring regulatory dilemma. In Canada, this conflict has been resolved by granting workers a legal immunity from liability under competition law for engaging in approved collective action to improve or defend their terms and conditions of work. However, the zone …

Exploration Of Chemical Space With Partial Labeled Noisy Student Self‑Training And Self‑Supervised Graph Embedding, Yang Liu, Hansaim Lim, Lei Xie

Publications and Research

Background Drug discovery is time-consuming and costly. Machine learning, especially deep learning, shows great potential in quantitative structure–activity relationship (QSAR) modeling to accelerate drug discovery process and reduce its cost. A big challenge in developing robust and generalizable deep learning models for QSAR is the lack of a large amount of data with high-quality and balanced labels. To address this challenge, we developed a self-training method, Partially LAbeled Noisy Student (PLANS), and a novel self-supervised graph embedding, Graph-Isomorphism-Network Fingerprint (GINFP), for chemical compounds representations with substructure information using unlabeled data. The representations can be used for predicting chemical properties such …
