Course-based research experiences (CREs) are powerful strategies for spreading learning and improving persistence for all students, both science majors and nonscience majors. Here we address the crucial components of CREs (context, discovery, ownership, iteration, communication, presentation) found across a broad range of such courses at a variety of academic institutions. We also address how the design of a CRE should vary according to the background of student participants; no single CRE format is perfect. We provide a framework for implementing CREs across multiple institutional types and several disciplines throughout the typical four years of undergraduate work, designed to a variety …

Energy-Conserving Numerical Scheme For The Poisson-Nerst-Plank Equations, Julienne Kabre

Mathematics Faculty Proceedings, Presentations, Speeches, Lectures

Preliminary report.
The Poisson-Nernst-Planck equations are a system of nonlinear partial differential equations that describe flow of charged particles in solution. In particular, we are interested in the transport of ions in the biological membrane proteins (ion channels). This work is about the design of numerical schemes that preserve exactly (up to roundoff error) a discretized form of the energy dynamics of the system. We will present a scheme that achieves the goal of preserving the energy dissipation law and some preliminary numerical results.

Model Based Security Testing For Autonomous Vehicles, Seana Lisa Hagerman

Electronic Theses and Dissertations

The purpose of this dissertation is to introduce a novel approach to generate a security test suite to mitigate malicious attacks on an autonomous system. Our method uses model based testing (MBT) methods to model system behavior, attacks and mitigations as independent threads in an execution stream. The threads intersect at a rendezvous or attack point. We build a security test suite from a behavioral model, an attack type and a mitigation model using communicating extended finite state machine (CEFSM) models. We also define an applicability matrix to determine which attacks are possible with which states. Our method then builds …

Peccit: An Omniscient Debugger For Web Development, Zachary Ryan Azar

Electronic Theses and Dissertations

Debugging can be an extremely expensive and time-consuming task for a software developer. To find a bug, the developer typically needs to navigate backwards through infected states and symptoms of the bug to find the initial defect. Modern debugging tools are not designed for navigating back-in-time and typically require the user to jump through hoops by setting breakpoints, re-executing, and guessing where errors occur. Omniscient debuggers offer back-in-time debugging capabilities to make this task easier. These debuggers trace the program allowing the user to navigate forwards and backwards through the execution, examine variable histories, and visualize program data and control …

Photoassisted Generation Of Complex N, O, S Polyheterocycles, Weston James Umstead

Electronic Theses and Dissertations

This research set out to continue the exploration and diversification of excited state o-azaxylylene cycloadditions, utilizing both pre-photochemical and post-photochemical modifications.

Pre-photochemical modifications came through the addition of heteroatoms, namely nitrogen and oxygen, to the tether that links the unsaturated photopendant to the photogenerated o-azaxylylene. Photochemistry resulted in the formation of new, interesting N, O, S polyheterocycles.

Post-photochemical modifications took place through several different cycloaddition reactions, including a [4+2] hetero-Diels Alder reaction, a [4+2] Povarov cyclization, a [3+2] nitrile oxide addition, and a [3+2] nitrone cyclization. These reactions were applied first to a model system, and then to …

Can The Children Of Immigrant Mothers Have Levels Of Health And Achievement As High As Those Of Children Of Mothers In The Host Population? Longitudinal Data From Australia, Julie Robinson

Papers from the International Association for Cross-Cultural Psychology Conferences

The high levels of immigration currently experienced by many Western counties have seen the development and wellbeing of the children of immigrants become an important research issue. However, findings about the developmental trajectories and outcomes for children of immigrants are highly inconsistent. In addition, identifying the factors that predict these outcomes has been hampered by the widespread confounding of parents’ immigration status with other predictors (e.g., mothers’ education, and fluency in the language of the host country). Immigration to Australia offers a context in which the influence of some of these variables can be untangled. Most recent immigrants are highly …

Measuring Urban High School Student Outcomes In A Protein Design Course, James Gillahan

Undergraduate Research Posters 2016

STEM (Science Technology Engineering and Mathematics) focused high schools have previously shown promising outcomes in the urban districts, where low income students have lower graduation rates, college acceptance and less access to advanced fields of study as compared to students of wealthier school districts. Modeling a protein design course from a private school, we aim to develop curriculum for a biotechnology course for an urban high school. Biotech is an emerging multidisciplinary field that could have similar outcomes to STEM education. We also aim to measure outcomes including student perspective of resulting STEM and career choice, using ethnographic methods.

Sequential And Dynamic Rna:Rna Base-Pairing Interactions Between U6atac And U12 Snrnas Predicted To Form Helix 1a And Helix 1b, Maitri Patel, Jagjit Singh

Undergraduate Research Posters 2016

In eukaryotes, pre-mRNA splicing is important step for gene expression. Splicing is a two-step process which is carried out by a multi-megadalton molecular weight ribonucleoprotein (RNP) machinery called spliceosome. Spliceosome converts pre- mRNA to mRNA by removing non-coding sequence (introns) and splice together coding sequence (exons). Mammalian pre-mRNA are spliced by two different class of spliceosomes which are known as U2- and U12- dependent spliceosomes. U12 dependent spliceosome is composed of five small nuclear RNAs (snRNA). As compared to U2-dependent spliceosome, there is very less known about the catalytic process of U12-dependent splicing. U6atac and U12 snRNA are central to …

Bioinformatic Analysis Of The Sodium Hydrogen Exchanger Protein In Plasmodium Yoelii, Jamira Virk, Raghavendra Yadavalli

Undergraduate Research Posters 2016

Since its discovery over 100 years ago, malaria has been the most important parasitic disease in the world. Malaria affects about 300 to 500 million people every year; killing 5 million people every year. The most virulent causative agent in humans is Plasmodium falciparum; it is an important member of the phylum Apicomplexa, which also includes Toxoplasma gondii. These organisms contain specialized, unique structures, including rhoptry organelles. In Plasmodium and Toxoplasma gondii, they assist invasion into the host cell. Analyses have been performed on proteins located in rhoptries in Toxoplasma and Plasmodium. Among the proteins that have been analyzed, the …

Synthesis And Characterization Of Lectin Mimetics (Neo-Lectins), Czharena Kay Rama, Joshua Whited

Undergraduate Research Posters 2016

The cell surface expresses a variety of carbohydrates such as glycoproteins, proteoglycans and glycolipids. They play critical roles in pathological and physiological processes, including cell signaling, immune responses, pathogen-host interactions, tumor metastasis, and other cellular events. Due to its function and uses in cell communication, it is a curious subject of observation for scientific research. The molecular mechanism of carbohydrate recognition is still undetermined, and lectins, sugar binding proteins, are used to analyze the particular structures expressed on the cell surface. Lectins are normally found in plants and animals, and the isolation process of lectins is laborious, toxic, immunogenic and …

Dialects Accents And Intelligence: A Study On Dialectal Perceptions, Taylor Moore

Undergraduate Research Posters 2016

Speech language pathologists are given the tools to help clients with a wide range of pathologies. Issues relating to speech, hearing, swallowing, etc can all benefit from a Speech language pathologist's insight. One area that can be difficult is dialect. People across America speak with many different dialects and speech language pathologists are taught to recognize these differences but not correct them. Dialect showcases culture but does not define intelligence. Dialects like African American Venacular English are rule governed systems of communication (Carter, 2012). The research done on AAVE is seemingly endless (Baugh, 1983; Pearson,2013; Robinson,2011; Carter 2010; Bronstein,1970......) and …

Elimination Of Acoustical Noise For Stm Examination Of Pentacene Crystallization On Si (001), William Myers, Mark Bowling

Undergraduate Research Posters 2016

Organic electronics are used in traditional solar cells and also in flexible electronics. Unfortunately, the conductivities of organic semiconductors are significantly lower than their inorganic counterparts. This project examines crystallization by directed selfassembly of the organic molecules via a surface reconstruction as a method to increase conductivity. The crystallization is characterized by Scanning Tunneling Microscopy (STM). In order to achieve optimal STM images, this work examined: (1) noise isolation, (2) etching sharp STM tips and (3) achieving reconstructed Si surface. The STM is housed in a glovebox to keep the surface reconstructions and organic molecules from degrading. However, acoustical noise …

Synchronization Of Cell Growth Makes Capture Of G2 Phase Cells Possible, Maryam Assar, Noopur Joshi

Undergraduate Research Posters 2016

During meiosis, homologous chromosomes, one set maternal and the other set paternal, pair with one another. Pairing is a prerequisite for crossing over, where allelic regions on homologs break and recombine with the corresponding homolog. This crossing over results in recombinant chromosomes that in turn increase genetic diversity. What causes the homologs to pair at specific sites is unknown. We are investigating whether specific DNA sequences are involved in pairing. Our first step to identify pairing sites involves mitotic cells of budding yeast in order to isolate pairing regions in sister chromatids. Mitotic cells are used instead of meiotic cells …

Identification Of Factors That Mediate Strand Exchange During Early Meiosis At Low Double Strand Break Levels, Isaac Kuragayla, Rima Sandhu

Undergraduate Research Posters 2016

Genetic recombination is essential in order to create diversity amongst all of the genetic information. Crossovers also contribute to segregation of homologous chromosomes to opposite spindle poles during the first meiotic division. Meiotic strand exchange in Saccharomyces cerevisiae, budding yeast, aims to diversify genetic information in the resulting gametes which in budding yeast are called spores. While Dmc1 and Rad51 are two proteins that are known to play a role in double strand break (DSB) repair, the exact function of Rad51 is still unclear. It is known that Rad51 is responsible for strand exchange in mitosis, but it is still …

Biostatistical Analysis On The Effects Of The Circadian Clock & Glucose Genes On Different Feeding Regimens, Rana Faraj, Nikkhil Velingkaar

Undergraduate Research Posters 2016

Circadian clocks are internal biological systems that control many physiological processes. The circadian clock is considered to be the master regulator of metabolism in mammals. The molecular metabolism is not very well known. The circadian clock regulated expression in metabolic enzymes and in turn, diet also regulates circadian clock on a molecular level. To better understand the interaction between circadian clock and metabolism, mice were subjected to different feeding regimens and metabolic tissue, such as liver and skeletal muscles, have been collected across the circadian cycle. Expression of genes have been analyzed in the liver using RT-QPCR. Large set of …

Understanding The Expression And Trafficking Of Plasmodium Falciparum Maurer’S Clefts Proteins, Sophia Degeorgia, Katharine Komisarz, Ashka Patel, Raghavendra Yadavalli

Undergraduate Research Posters 2016

Malaria is a potentially fatal disease caused by parasites in the genus Plasmodium. Of the five species that cause human malaria, P. falciparum causes an estimated 1 million deaths annually, particularly in young children in sub-Saharan Africa. Plasmodium falciparum is most commonly found in tropical and subtropical regions of the world. After invasion into human red blood cells, parasite induced transport structures known as Maurer's clefts, are formed within red cells. In previous studies, two Maurer's clefts proteins were identified; an approximately 130 kDa peripheral membrane protein and a 20-kDa integral membrane protein. Immunofluorescence and confocal microscopy identified both proteins …

Effect Of Calorie Restriction On Circadian Rhythms Of Glycolytic Enzymes In Mice, Enas A. Muhammad, Artem Astafev, Kuldeep Makwana

Undergraduate Research Posters 2016

Multicellular and unicellular organisms have all proven to exhibit circadian rhythms which persist over approximately 24 hours. This internal time keeping system is responsible for regulating the body's biological functions. It has been known that calorie restriction effects circadian rhythms by causing a response in clock gene expression. These clock genes react to food intake and become either upregulated or downregulated accordingly. With glycolysis being a biological pathway that occurs in most organisms, measuring glycolytic gene expression in the liver tissue of young male mice becomes of interest. More specifically, hexokinase, PFK-1, and pyruvate kinase are the enzymes of interest. …
