A Gpu Accelerated Genetic Algorithm For The Construction Of Hadamard Matrices, Andras Balogh, Raven Ruiz

School of Mathematical & Statistical Sciences Faculty Publications

We use a genetic algorithm to construct Hadamard Matrices. The initial population of random matrices is generated to have a balanced number of +1 and −1 entries in each column except the first column with all +1. Several fitness functions are implemented in order to find the most effective one. The crossover process creates offspring matrix population by exchanging columns of the parent matrix population. The mutation process flips +1 and −1 entry pairs in random columns. The use of CuPylibrary in Python on graphics processing units enables us to handle populations of thousands of matrices and matrix operations in …

Background: We investigated whether surveillance imaging had an impact on post-relapse survival in patients with rhabdomyosarcoma (RMS). We hypothesized that relapse detected by imaging (group IM) would be associated with longer survival compared with relapse detected with a clinical sign or symptom (group SS).

Materials and methods: We performed an observational multi-institutional study in 127 patients with relapsed RMS comparing overall survival (OS) after relapse using Kaplan-Meier and Cox proportional hazards analyses.

Results: Relapse was detected in 60 (47%) group IM and 67 (53%) SS patients. Median follow-up in survivors was 4 years (range 1.0 to 16.7 y). Four-year OS …

Joubert syndrome (JS), a well-established ciliopathy, is characterized by the distinctive molar tooth sign on brain MRI, ataxia, and neurodevelopmental features. Other manifestations can include polydactyly, accessory frenula, renal, or liver disease. Here, we report individuals meeting criteria for JS with de novo heterozygous variants in SLC30A7 (Chr1p21.2). The first individual is a female with history of unilateral postaxial polydactyly, classic molar tooth sign on MRI, macrocephaly, ataxia, ocular motor apraxia, neurodevelopmental delay, and precocious puberty. Exome sequencing detected a de novo heterozygous missense variant in SLC30A7: NM_133496.5: c.407 T > C, (p.Val136Ala). The second individual had bilateral postaxial polydactyly, molar …

Medicaid Expansion: Changes In Individual Health Outcomes, Julie Norman

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Affordable Care Act is one of the biggest changes in the American healthcare system in the 21st century. One element of the ACA is medicaid expansion, which opened up federal funding for states to cover any individual earning below 138% of the federal poverty line. 21 states expanded medicaid in 2014 while 12 haven’t expanded. This paper utilizes the disparity for a natural experiment to determine the efficacy of the program. Outcome variables of interest include measurements of individual health, health access and utilization, and premature death rates. The results indicate positive, but small improvements due to the policy, …

A Bayesian Hierarchical Approach For Modeling Virtual Species With Realistic Functional Trait Relationships, Sarah Bogen

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Understanding the spatial and temporal dynamics of plant populations has important implications for the fields of ecology and conservation. A rich body of mathematical modeling approaches, including reaction-diffusion equations and integrodifference equations, have been developed to mechanistically model population spread based on species demography and seed dispersal characteristics. However, with over 390,000 plant species on Earth, it is not feasible to collect complete information on all species for the purpose of drawing generalized conclusions. One means of overcoming such a problem is through trait-based modeling, which seeks to represent realistic combinations of organismal traits rather than focusing on individual species. …

Applied Deep Learning: Case Studies In Computer Vision And Natural Language Processing, Md Reshad Ul Hoque

Electrical & Computer Engineering Theses & Dissertations

Deep learning has proved to be successful for many computer vision and natural language processing applications. In this dissertation, three studies have been conducted to show the efficacy of deep learning models for computer vision and natural language processing. In the first study, an efficient deep learning model was proposed for seagrass scar detection in multispectral images which produced robust, accurate scars mappings. In the second study, an arithmetic deep learning model was developed to fuse multi-spectral images collected at different times with different resolutions to generate high-resolution images for downstream tasks including change detection, object detection, and land cover …

Nursing Perspectives And Opinions On Early Or Delayed Sepsis Treatment: A Mixed Methods Approach, Pamela L. Harris

Theses and Dissertations (ETD)

Purpose. Each year at least 1.7 million adults in America develop sepsis. Sepsis can lead to life threatening organ dysfunction, severe hypotension, and death when severe sepsis or septic shock is involved. Sepsis is responsible for 50% of acute kidney injury (AKI), which is the most common form of organ dysfunction seen in critical care. Sepsis associated AKI results in loss of, or decreased renal function, is associated with adverse long-term outcomes, and carries a higher mortality rate than non-septic AKI, sepsis without AKI, or septic shock without AKI. Surviving sepsis guidelines suggests a 1-hour window from the time of …

Inflammatory Response Following Hemorrhagic Stroke: The Role Of Cytokines, Patrick Devlin

Theses and Dissertations (ETD)

Hemorrhagic stroke is a dangerous form of stroke resulting from the rupturing of weakened blood vessels, releasing blood that increases intracranial pressure and causes the death of surrounding tissue. Treatment options are improving but remain limited, as evidenced by this condition being characterized by high rates of mortality as well as long-term morbidity. Unregulated inflammatory responses that occur following injury may be partially to blame for these poor outcomes. In response to any injury, the immune system releases cytokines to recruit immune cell activation and promote inflammation. But after hemorrhagic stroke, whether aneurysmal subarachnoid hemorrhage (aSAH) or intracerebral hemorrhage (ICH), …

Patients With Lung Cancer Of Different Racial Backgrounds Harbor Distinct Immune Cell Profiles, Yitian Xu, Licheng Zhang, Jose Thaiparambil, Sunny Mai, Dimuthu Nuwan Perera, Jilu Zhang, Ping-Ying Pan, Cristian Coarfa, Kenneth Ramos, Shu-Hsia Chen, Randa El-Zein

Faculty, Staff and Students Publications

UNLABELLED: Tumors accumulated with infiltrated immune cells (hot tumors) have a higher response rate to immune checkpoint blockade, when compared with those with minimal T-cell infiltration (cold tumors). We report here that patients with lung cancer with different racial backgrounds harbored distinct immune cell profiles in the tumor microenvironment. Compared with African Americans (AA), Caucasian Americans (CA) exhibited increased immune cell infiltration and vasculature, and increased survival. Changes of survival and immune profile were most pronounced among active smokers and nonsmokers, compared with former smokers and total patients. Neighborhood analysis showed that immune cells accumulated around cancer cells in CAs …

Exploring Clinical Implications Of Consensual Non-Monogamy: A Proposed Intake Assessment Tool, Rebecca Tuttle

Dissertations

Relationships in the United States are often assumed to adhere to heteronormative and mononormative standards, which is problematic because a significant minority of individuals are neither heterosexual nor monogamous (approximately 4.5% and 4% of the United States population, respectively). As a result of mononormative biases in particular, alternatives to monogamy, such as consensually non-monogamous relationships, are often socially stigmatized and clinically pathologized. The existing research on consensually non-monogamous individuals indicates, despite negative assumptions, those who engage in consensually non-monogamous relationships demonstrate psychological well-being, physical health, and levels of relationship satisfaction comparable to their monogamous counterparts. While engaging in consensually non- …

The Effect Of Increasing Intestinal Short‐Chain Fatty Acid Concentration On Gut Permeability And Liver Injury In The Context Of Liver Disease: A Systematic Review, Keith Pohl, Prebashan Moodley, Ashwin Dhanda

Peninsula Medical School

Background and AimThe gut barrier protects the liver through tight junctions, which are disrupted in liver disease either from dysbiosis, inflammation, or the effects of ingested compounds such as alcohol. Strengthening of the gut barrier may ameliorate liver injury of varying etiologies. Short chain fatty acids (SCFAs) have been shown to improve gut barrier function. This systematic review aims to synthesize all studies that have trialed SCFA supplementation as a therapy for liver disease.MethodsA systematic review assessing the impact of SCFA supplementation on liver injury and intestinal permeability was conducted. All forms of intervention that specifically increased intestinal SCFA concentration …

Development Of Microsatellites Markers For The Deep Coral Madracis Myriaster (Pocilloporidae: Anthozoa), Diana C. Ballesteros-Contreras, Lina M. Barrios, Richard Preziosi

School of Biological and Marine Sciences

AbstractIn 2013 Colombia made an important step towards the construction and management of Marine Protected Areas (MPAs) by establishing the first Deep Corals National Park (PNNCP). Inside this MPA, the coral Madracis myriaster (Cnidaria: Pocilloporidae) was found as the main reef builder, offering habitat for many species of fish and invertebrates. In order to improve the study of deep-sea coral habitats, their connectivity and prospective management, nine new genetic markers (microsatellites) were developed for M. myriaster and tested in samples from PNNCP. We present the assessment of these markers, with a specificity for the deep coral, and its prospective use …

School of Biological and Marine Sciences

Globally, zoological collections may host public events after usual opening hours including festivals, special tours and evening events, in order to generate income. During the summer of 2014, The Zoological Society of London held a series of nine evening events during which zoos’ opening hours were extended, with entertainment offerings such as tours and visitor events provided. This study investigated the effect of evening events on the behaviour and enclosure use of five Sumatran tigers (Panthera tigris sumatrae) at ZSL London Zoo. Instantaneous focal sampling was utilised to collect behavioural data and enclosure zone occupancy. Measures of visitor density, crowd …

A Multidimensional Metabolomics Workflow To Image Biodistribution And Evaluate Pharmacodynamics In Adult Zebrafish, Madelyn M Jackstadt, Casey A Chamberlain, Steven R Doonan, Leah P Shriver, Gary J Patti

2020-Current year OA Pubs

An integrated evaluation of the tissue distribution and pharmacodynamic properties of a therapeutic is essential for successful translation to the clinic. To date, however, cost-effective methods to measure these parameters at the systems level in model organisms are lacking. Here, we introduce a multidimensional workflow to evaluate drug activity that combines mass spectrometry-based imaging, absolute drug quantitation across different biological matrices, in vivo isotope tracing and global metabolome analysis in the adult zebrafish. As a proof of concept, we quantitatively determined the whole-body distribution of the anti-rheumatic agent hydroxychloroquine sulfate (HCQ) and measured the systemic metabolic impacts of drug treatment. …

Just Strict Liability, Cristina Carmody Tilley

Cardozo Law Review

Theorists who contend that tort is designed to do justice cannot explain strict liability. The strict sector plagues these scholars because it extracts payment from defendants who have acted reasonably and are therefore considered innocent. If tort is about wronging and recourse, then strict liability makes no sense. Stymied, justice theorists have ceded the sector to economically minded counterparts who are concerned primarily with efficient market outcomes. As this theory has taken hold, some have declared strict liability “dead.” This Article offers a justice theory of the interpersonal wrong that permits liability in the absence of traditional fault—namely, the delegation …

Lgbtq Youth And The Promise Of The Kennedy Quartet, Michael J. Higdon

Cardozo Law Review

The Supreme Court has only issued four opinions endorsing the constitutional rights of sexual minorities, each of them authored by Justice Anthony Kennedy. These four cases, which this Article refers to collectively as “the Kennedy Quartet,” have done much to advance the equality of LGBTQ adults in the United States. The question remains, however, as to what extent those cases likewise protect LGBTQ children. Far from simply being an academic question, this issue has taken on increased urgency as legislators in a number of states—thwarted by the Kennedy Quartet in their ability to target LGBTQ adults—have turned their attentions to …

The incidence of diastolic dysfunction increases with age in both humans and mice. This is characterized by increased passive stiffness and slower relaxation of the left ventricle. The stiffness arises at least partially from progressively increased interstitial collagen deposition because of highly secretory fibroblasts. In the past, we demonstrated that AMPK activation via the drug 5-aminoimidazole-4-carboxamide riboside (AICAR) in middle-aged mice reduced adverse remodeling after myocardial infarction. Therefore, as an attempt to normalize the fibroblast phenotype, we used 21-mo-old male and female mice and treated them with AICAR (0.166 mg/g body wt) where each mouse was followed in a functional …
