The goal of our research is to synthesize new iron complexes that can reduce carbon dioxide. Increasing the electron richness of iron tricarbonyl diimine complexes, which have been synthesized previously in the Carroll research group, will increase the likelihood of a reaction with carbon dioxide occurring. We have taken two approaches to changing the electron density in the complexes. First, we reacted the complex Fe((CF3)2ArDABMe)(CO)¬3 with the reducing agent potassium on graphite, in order to reduce either …
Kinetic Analysis Of Glu115ala Cytosolic Human Malate Dehydrogenase Mutation Shows A Change In Activity On Non-Native Substrate Phenylpyruvate, Kailey Paar
Chemistry & Biochemistry Student Scholarship
The cytosolic human enzyme, malate dehydrogenase (MDH1), is believed to have a significant effect on the proliferation of cancerous cells. This enzyme oxidizes NADH to NAD+ as it converts oxaloacetate (OAA) to malate. This oxidation of NADH provides the needed NAD+ to cancer cells, which require NAD+ as they upregulate glycolysis in aerobic conditions. Targeting MDH1 can reveal new therapeutic treatments for cancer by preventing the conversion of OAA to malate and depleting NAD+ stores in cancer cells, which can be done by mutating residues in the enzyme and assessing the change in activity. Here we show the replacement of …

Francis Radics ’22
Major: Biochemistry
Faculty Mentor: Dr. John Breen, Chemistry and Biochemistry
Indicator displacement assays are based on the optical signal modulation of a noncovalently bound indicator upon dissociation by an analyte species. Our work has focused on exploring the lower detection limits for luminescent displacement assays for inorganic phosphate in seawater using complex ions containing two di(2-picolyl)amine ligands (also called DPA or bis(2-pyridylmethyl)amine), each coordinating a zinc cation. Following the work of B.D. Smith and coworkers, we have prepared three ligands by covalently attaching two DPA moieties, 2,6-bis(chloromethyl) benzene, and 2,6-bis(chloromethyl)-4-methylphenol, and 1,2-phenylenedimethylamine, for assays with 6,7-dihydroxy-4-methanesulfonic acid …

Mentor: Dr. Maria Carroll, Chemistry and Biochemistry
Our research focuses on synthesizing and studying the properties of metal complexes that contain redox active ligands. Ligands are molecules or ions that can bind to a metal ion, and this particular class of ligands is interesting because they can either accept or lose electrons. We synthesized zinc complexes, in order to measure the reduction potentials of the ligands, which provide information about the ease with which they accept electrons. We then synthesized iron complexes and determined their structures. These complexes are potentially …

Jordan DeMoura ’22
Major: Mathematics
Faculty Mentor: Dr. Su-Jeong Kang, Math
This research is to investigate lines on a smooth projective surface. A quadric surface contains two families of planes that provide a ruling of the surface. A cubic surface contains twenty-seven lines, and we provide a complete description of these lines for a Fermat cubic surface. Furthermore, under the Plucker embedding, we show that each family of the lines on a quadric surface corresponds to plane conic curves lying on complementary planes in the projective space of dimension five.
A Damaged Reputation: Nuclear Depictions In Entertainment Media, Alexander Cannon
A Damaged Reputation: Nuclear Depictions In Entertainment Media, Alexander Cannon
Chemistry & Biochemistry Student Scholarship
This paper, originally written for Dr. Adamus Liotta in an honors chemistry class, explores the possibility of a significant influence over public common sense found in the depictions of entertainment media. Through careful analysis and interpretation of Godzilla, The Simpsons, Fallout, and Call of Duty, this paper finds a synergy throughout this diverse range of audience, medium and historical origin, which culminates in an effect much greater than the sum of its parts. This effect frames nuclear science, of any kind, in a hyperbolically catastrophic and horrific light, reinforcing an excessively cautious, pessimistic public perspective on nuclear technology …

We evaluate the ability of self-supervised deep learning for Poisson denoising of Single-Molecule Localization Microscopy (SMLM) in addition to the impact denoising can have on the ability to locate molecules within the Single-Molecule Localization Microscopy images. SMLM images are predominantly corrupted with Poisson noise. There is a need for a superior technique to provide accurate SMLM images in order for scientists to gain a better understanding of the functions of live cells at the nanoscale. By denoising SMLM images prior to the images undergoing the current state- of-the-art super-resolution …

Faculty Mentor: Dr. Su-Jeong Kang, Mathematics
The process of dividing shapes into triangles is called triangulation, and it is possible to abstract the idea of a triangle to higher dimensions, where it will be called a simplex in n-dimensions, or an n-simplex. I studied this process of generalized triangulation, or decomposition, in order to find an optimal decomposition of a 5-cube to help improve the bounds on the general case of an n-cube.

Mathematics & Computer Science Student Scholarship
Major: Finance and Mathematics
Faculty Mentor: Dr. Joseph Shomberg, Mathematics
The Black-Scholes model was developed by Fisher Black and Myron Scholes in the 1970s to price stock options. Since then the model has been suited to price so-called intangible assets such as trademarks and patents. In this paper, we investigate the related Black-Scholes-Merton model and the relevant characteristics of patents in order to associate patents as real options. After describing patents as options, we apply the Black-Scholes-Merton model to the valuation of the intangible assets. Special attention is given to modeling volatility and the cost of delay in order to …

ZoeJ and Marcoliusprime are mycobacteriophage capable of infecting tuberculosis causing bacteria via the lytic and lysogenic cycles. The lytic cycle is the form of viral replication that results in cell death. Lysogeny involves phage DNA being integrated with the DNA of the host cell and preserved through binary fission. However, the bacteria causing tuberculosis do not die in the lysogenic phase. This research project will involve creating mutants of ZoeJ and Marcoliusprime that will not contain the genes …

Phages are viral bodies that infect bacterial hosts, and have shown promising applications as alternatives to antibiotics for the treatment of bacterial infections. This project examines the morphology of siphoviridae mycobacteriophage, which have long, flexible, non-contractile tails as well as the characteristic head, called a capsid. Using electron microscopy photos of sequenced phages, tail length and capsid diameter were measured and compared to further characterize morphological relationships between genetically distinct phages. The data presented has the potential to work as a diagnostic tool to classify unsequenced phages to genetically …

We designed two neural networks that can learn how to classify three different types of partial differential equations (PDEs). Our data consists of numerical solutions to three categories of PDEs: Burger’s, Diffusion, and Transport equations. Using TensorFlow and the Keras library, we performed two tasks – the first a binary classification of Burger’s and Diffusion equation data, and the second a multi-label classification incorporating the Transport Equations as well. Our binary classification network requires vector labels to perform efficiently. Furthermore, our tertiary classification network …

Surface Mutation Thr34his Facilitates Purification Of Haemophilus Influenza Carbonic Anhydrase Via Metal Affinity Chromatography, Caroline Foley, Dr. Kathleen Cornely
Surface Mutation Thr34his Facilitates Purification Of Haemophilus Influenza Carbonic Anhydrase Via Metal Affinity Chromatography, Caroline Foley, Dr. Kathleen Cornely
Chemistry & Biochemistry Student Scholarship
In order to pursue Haemophilus influenza carbonic anhydrase (HICA) as a potential drug target, easy and efficient purification methods must be developed. While immobilized metal affinity chromatography (IMAC) may be used, complications with polyhistidine tags is a concern. Inspired by the endogenous metal affinity of Escherichia coli β-carbonic anhydrase (ECCA), we suggest that the generation of histidine clusters on HICA’s surface will facilitate its purification by metal affinity chromatography without the potential interference of His-tags. Here we investigate the Thr34His mutation as a method to generate metal affinity in HICA. Since Thr34His is located only 5.3 Å away from His32, …

Engineering & Physics Faculty Publications
Lifetimes of individual Na2 ro-vibrational levels of the 21Σ + u double well-state have been measured using a delayed photoionization technique. Ground state Na2 produced in a molecular beam is excited resonantly by the doubled output of a pulsed dye laser in the range 333 – 357 nm and then ionized by a 532 nm photon from a time-delayed Nd:YAG laser. By appropriate excitation laser tuning and systematic variation of the probe laser delay, ro-vibrational level resolved lifetimes are obtained for v=25- 49. The double well state lifetime values are found to decrease from about 50 ns at v=25 to …

E56h + E59h Mutation Affects Binding Of The Recombinant Haemphilus Influenza Carbonic Anhydrase To A Ni-Nta Column, Eric D. Lebel, Kathleen Cornely
Chemistry & Biochemistry Student Scholarship
The Haemophilus influenzae carbonic anhy- drase (HICA) is important in converting carbon dioxide to bicarbonate in bacteria. Endogenous cellular proteins, like Escherichia coli carbonic anhydrase (ECCA), have been observed to bind to a Ni-NTA column, which can be used as a means of protein purification. The possibility ex- ists that proteins that do not normally bind to Ni-NTA, like HICA, can be engineered using site directed mutagenesis to introduce histidine resi- dues that would give the protein the capability to bind, allowing for a one-step purification method. Site-directed mutagenesis was used to introduce the double mutation of E56H + E59H …

Comparison Of Absorption, Fluorescence, And Polarization Spectroscopy Of Atomic Rubidium, Seth T. Ashman, Cayla Stifler, Joaquin Romero
Engineering & Physics Faculty Publications
An ongoing spectroscopic investigation of atomic rubidium utilizes a two-photon, single-laser excitation process. Transitions accessible with our tunable laser include 5P1/2 (F ′ ) ← 5S1/2 (F) and 5P3/2 (F ′ ) ← 5S1/2 (F). The laser is split into a pump and probe beam to allow for Doppler-free measurements of transitions between hyperfine levels. The pump and probe beams are overlapped in a counter-propagating geometry and the laser frequency scans over a transition. Absorption, fluorescence and polarization spectroscopy techniques are applied to this basic experimental setup. The temperature of the vapor cell and the power of the pump and …
Transubstantiation And Quantum Physics: The Parallels Of Mystery In Religion And Science, Zachary Sexton
Transubstantiation And Quantum Physics: The Parallels Of Mystery In Religion And Science, Zachary Sexton
Spring 2013, Science and Religion
As the study of physics has progressed into the abstract realm of quanta, some have argued that the notion of transubstantiation is an unreasonable understanding of the Eucharist. However, when confronted with the uncertainty that modern physics presents, sharp parallels between this uncertainty and the metaphysical mysteries of transubstantiation. If it is reasonable to accept uncertainty in quantum physics, then it should be reasonable to accept the mysteries within the metaphysical world.
Heisenberg’S Uncertainty Principle, Matthew Santos
Heisenberg’S Uncertainty Principle, Matthew Santos
Spring 2013, Kuhn's Philosophy of Science
In 1926 Werner Heisenberg’s Uncertainty Principle set the field of quantum mechanics on a trajectory riddled with indeterminacy, a trajectory which stood in stark contrast with the classical Newtonian world causality and origin. In doing so, Heisenberg effectively created a new standard by which physicists conducted their science, broadened the scope of that science, and altered the very worldview of those physicists. Such paradigmatic upheaval fits the philosophical model of scientific progress posited by Thomas Kuhn. However, in the ever-changing and still-evolving world of quantum mechanics, Heisenberg’s revolutionary work uniquely strays from Kuhn’s model in its further implications.
Diffusion Of Mobile Payment Systems Among Microentrepreneurs In Kenya And Tanzania, Dionne Nickerson
Diffusion Of Mobile Payment Systems Among Microentrepreneurs In Kenya And Tanzania, Dionne Nickerson
Annual Celebration of Student Scholarship and Creativity
The rapid rise of Kenya's mobile payment system, M-PESA , has grasped the attention of policy makers and private enterprise alike. In just six years M-PESA has transformed how money flows throughout Kenya, and similar systems are gaining traction elsewhere in Africa. This project examines the impact of mobile payment system adoption on the economic advancement of Kenyan and Tanzanian microentrepreneurs. This work will further the understanding of mobile payment systems’ contribution to the economic growth of microenterprises, which may have implications for poverty reduction in these two nations.
