ATC Suicide Rates
Abdullah Alasmri, Mohammed Alfawaz, Tyler DeBettignies, Darren Mushkin, Hudson Pettit, Minsu Song
Mental health is a crisis today, and the aviation industry has no shortage. Air traffic controllers are vital to the successful operation of every flight every single day. Finding ways to support air traffic controllers in their extremely stressful job needs to happen, and one of the first steps is determining some of the factors. Our group wants to study and identify possible casualties of stress and mental health crises for air traffic controllers, and how to prevent them.
Exhibit #25
Pilot Fatigue
Grace Appelbaum, Matthew Liguori, Mallory Machala, Hafsa Mou and Rebecca Treis
This study aims to identify the cognitive and psychomotor impairments that pilots can experience due to sleep deprivation and how those impairments can impact decision-making abilities in stressful environments such as those encountered in emergencies. Our study aims to show the effects of sleep deprivation on pilots and how it affects them in stressful situations on the flight deck. That encompasses multiple avenues of situations, such as effective teamwork, correctly going through the entire checklist, split decision-making, and so on. The ability to perform these tasks perfectly is complex, and adding fatigue to this equation opens pilots up to making errors. In a high-consequence environment, errors such as not following the checklist could have devastating consequences..

Accidents and Implications for Training and Protocol Enhancement
Savannah Baker, Jack Liu, Nolan Mank, Ricardo Romero, Tinghao Zhang
Looking to the twenty years preceding Avianca Flight 52, what aviation accidents existed in that time frame that regarded miscommunications between flight crews and air traffic controllers? How did those incidents influence the protocol and training procedures within this accident, and what factors were not accounted for? How did those failures influence communication between flight crews and ATC for the next ten years?

Airline Organizational Culture and Its Correlation to Aviation Accidents
Mary Cortesi, Yichen Liu, Woo Cheon Park, Ellie Volansky, Bojian Yu
Our research will focus on investigating the relationship between airline organizational culture and aviation accidents between 2010 and 2024, in order to understand how basic beliefs, practices, and values within aviation organizations affect safe operations. We will study specific aspects of organizational culture, such as leadership style and communication practices and the connection between them and the frequency and severity of aviation accidents. And we will report what we can be learned from accidents caused by distrust or power imbalance among crew members in the past? How do these events affect changes in aviation policies, procedures, and training? So as to reduce the possibility of future accidents.
Exhibit #21
Influence of Organizational Culture on Aircraft Safety
Addison Brazile, Nicholas Carey, Mike Morell, Jongchan Park, Will Weaver
Aviation safety has been an integral part of the industry for as long as it has existed. However, it has been a reactive type of safety, instead of a proactive type. We wanted to look into what exactly causes that in different companies and organizations. Specifically with Boeing, ValuJet, Southwest, and other aviation corporates, we hope to find interesting information when we look into these. Potentially shedding some light on what exactly is going on behind the scenes in these operations.

Chuck's Chompers
Atticus Edge, Ben Haukap, Alfonso Morales, Maksim Juric, Gavin Ryan, Shayne Murphy, Michael Davies, Shiyan Nejat
Your print failed, and once again all of the filament you purchased has gone to waste. What should you do? Typically, many individual users of 3D printers are forced to buy more filament or send their failed prints off to larger recycling companies, as traditional desk size recycling systems range from $6,000 - $18,000.
Chuck鈥檚 Chompers decided that we wanted to find a way to design an affordable recycling system to safely recycle used filament and failed prints. Hence, the goal of our project (R3fil) is to design an automated machine that will perform grinding, heating, extrusion, and automatic spooling to recycle 3D filament while also being small enough to be used in an individual setting.

Natural Language Control for a Robotic Arm
Lucy Billadeau, Pascal Sikorski, Kaleb Yu
In this project, we introduce an approach for controlling robotic arms through natural spoken language. Unlike traditional methods that rely on a predefined set of explicit commands, our system is designed to interpret the user's intent. By leveraging Large Language Models, the system is able to process human speech and draw upon the appropriate robot action. This advances verbal control of the robotic arm such that it will be able to execute tasks with precision and flexibility given complex verbal instructions.

Project RADARS (Rocket Altitude Determination and Response System)
Colin Cummins, Tim Drake, Matthew Muetzel, Mary Otten
Every year, collegiate rocketry propulsion teams participate in nationwide competitions, such as, the Spaceport America Cup and NASA Student Launch. These competitions have various altitude requirements that the student-designed and built rockets must reach, in order to qualify. Teams will often use solid rocket motors for these competitions, which are not controllable once launched. However, this is where issues may arise, due to the various motor and atmospheric differences between initial testing and the competition launch. Project RADARS, Rocket Altitude Determination and Response System, aims to resolve this problem by integrating a dynamic altitude control system onboard the rocket. The system is a minor air braking mechanism that will autonomously extend or pull back flaps, either increasing or decreasing the drag and thus controlling the altitude.

Self-Launch Sailplane Utilizing Electric Driven Propulsion
Spencer Cochran, Sophia Collins, Amanda Kohne, Isabel Korzilius, and Camilyn Newbanks
Sailplanes, also known as gliders, are aircraft with no propulsion system. This project utilizes a self-launching propulsion system which are often powered by small jets, pistons, rotary or electric engines. The project requirements for an electric powered self-launching aircraft are broken into the subcategories of performance, design, manufacturing, and operation. The requirements for this design were selected from the 2023-2024 AIAA Electric Training Sailplane RFP, but not all requirements from the RFP will be applied. The design of this electric sailplane will be made up of two phases. The first phase includes the design and computations for a full-scale theoretical model. The theoretical model, with its 20 meter wingspan, will utilize computer modeling and ANSYS Fluent simulations to verify the aircraft鈥檚 performance. The second phase consists of the design, construction and flight of a test flight model. This flight model will be constructed as a scaled version, 4 meter wingspan, of the theoretical model to test the model鈥檚 configuration with a retractable propulsion system.

Fluidix - Lymphedema Treatment Device
Julia Brockhouse, Ether Dharmesh, Ryan Hilty, Jessica Robinson, Saloni Shringarpure
Each year, 1 in 1000 Americans suffer from lymphedema, a build-up of lymph fluid in the fatty tissues under the skin causing swelling and discomfort. Lymphedema pump devices have been proven to reduce swelling through at-home usage, but they do not match the superior effectiveness of lymphatic massages delivered by physical therapists. Such suboptimal efficiency extends the time patients spend in each pump treatment session, and this inactivity worsens lymphedema. Here, we have developed a pneumatic pump device to push fluid back into lymphatic vessels through sequential pumping from foot to groin, with segmented bladders that inflate from the back to the front of the leg to emulate a physical therapy massage. Pressure sensors embedded in the sleeve of the device allow precise measurement of the applied pressure and adjustment of the degree of inflation. This design is simultaneously adjustable and effective, allowing for patient-directed treatment without compromise of quality.

Optimization of Electrospraying for the Creation of Large Diameter Microsphere for
Vessel Occlusion
Rose Viguerie
This project aims to optimize the creation of PEG microspheres via electrospraying for use in several applications, one being vessel occlusion at the site where they are injected. The primary variable tested, the needle gauge, will be varied to obtain microspheres in a range of 100渭m to 500渭m while having a coefficient of variance lower than 20% (ideally around 10%). If time permits, further variable analysis will be performed (such as considering varying the voltage between the needle tip and the oil bath). After the microspheres鈥� physical parameters have been tweaked to fit the requirements, injection testing will be performed. The microspheres must be able to be injected via an insulin needle without aggregation occurring (this would interfere with the process of injection). The data gathered in this experiment will serve as a guideline for further electrospraying research by providing expected values for diameter.
Exhibit #66
Piezoelectric Hydrogels
James Baker
Biocompatible piezoelectric materials are a growing area of interest for biomedical engineering researchers for their potential rehabilitative and regenerative properties for electrically excitable cells. By further developing these materials, it may be possible to use them to better address issues such as volumetric muscle loss and nerve damage. For researchers to produce these piezoelectric devices, they must be able to robustly validate these materials as reliable forms of treatment. To accomplish this, researchers need systems that can measure the electrical properties of materials created in the laboratory before moving to clinical settings. Researchers often run into the problem that systems used for detecting
small currents produced by these materials are too expensive or too big for practical use. This project demonstrates the successful synthesis of Poly(vinylidene fluoride)-poly(ethylene glycol) hydrogels and proposes a low cost, portable design for a device to measure electric currents produced by piezoelectric hydrogels.

Shear Wave Tensiometer for Achilles Load Measurement in Animal Models
Patrick Hinkle
Shear wave tensiometry is a recently developed technique to directly measure in-vivo muscle-tendon loading in humans noninvasively by tracking the velocity of propagating
shear wave vibrations within a tendon to evaluate muscle-tendon loading. Though a proven technique in quantifying muscle-tendon loading in humans, shear wave tensiometry has not been scaled for use in animal models. A rodent animal model is an ideal platform for developing a shear wave tensiometer, but there are many challenges due to the size constraints of a rodent Achilles tendon. By mounting sensors to measurement probes in a free-floating support structure above the animal, the size constraints can be mitigated. The successful development of the device will allow future studies on changes in in vivo muscle function due to injury and potential treatment protocols for these injuries.

SmartCane Technology
Robert Bucks, Megan Chermack, Owen Miller, Jonel Olar, Cati Welby
Smart Cane aims to satisfy our goals of increasing both safety and independence for the large percentage of the population that rely on the use of canes for walking assistance. With this device, injuries can be prevented, and help will be alerted in the event of a fall. Our design utilizes Inertial Measurement Units (IMUs), which have the ability to track velocities and accelerations using the combination of a built-in accelerometer and gyroscope on a three-axis coordinate system. The IMU works hand-in-hand with a SMS radio to allow for SMS text messages to be sent from the cane directly to any cellular phone. With the combination of an IMU and SMS radio, the cane is capable of accurately sensing when a fall occurs and sending an immediate text message to a pre-selected emergency contact.

WaveBags
Michael McCormick, David Ruetten, Rebekah Weimholt
Our senior design project focuses on innovating the classic game of cornhole by incorporating an electronic scoring system through RFID (Radio-Frequency Identification) technology. This project aims to improve the gaming experience by eliminating manual scoring, giving players a seamless and automated scoring process. The cornhole boards are equipped with several antennas that read chips that are embedded in each of the cornhole bags. As the cornhole bag is thrown onto the boards, the RFID technology will be received and will accurately record the score following the throw of the final black cornhole bag. This system will not only add a technological edge to the traditional game of cornhole, but also will introduce a more efficient and engaging way to play the popular recreational game.

尾-mannosylation by hydrogen-bond-mediated aglycone delivery
Cece Fitz
Stereocontrolling the glycosylation reactions is a constant quest in the field of glycosciences, and often proves to be quite cumbersome. The hydrogen-bond-mediated aglycone delivery (HAD) method provides control of the stereoselectivity in the glycosylation of a variety of sugar substrates, allowing for the formation of difficult 1,2-cis glycosides. The HAD method relies on the formation of an intermolecular hydrogen bond between the nitrogen atom on the protecting group of the glycosyl donor with the hydroxyl group of the glycosyl acceptor. This interaction allows for a subsequent syn-attack by the approaching nucleophile, allowing to achieve a powerful stereocontrolling mode for the glycosidic bond formation. Reported herein is the synthesis of a novel mannosyl donor capable of HAD and its applications in glycosylation.

Characterization of Photoreactive Dibenzothiophene Sulfoximine Derivatives
Nicolas Keller
The Bolm-McCulla reaction describes a photolysis of dibenzothiophene sulfoximine which yields two reactive intermediates via S鈥揘 and S鈥揙 bond cleavage. Photocleavage of DBT sulfoximines releases a nitrene product followed by atomic oxygen [O(3P)] upon irradiation with UV-A light. Studies of O(3P) in solution have been hindered by the high energy photons needed to generate this intermediate from known methods. Additionally, previous work by the McCulla group has demonstrated that the rate of reactive atomic oxygen release may be altered by the electronic effects of substituent groups placed on DBTO. A water-soluble molecule 4,6-diacetoxymethyl DBT sulfoximine has been synthesized which may produce O(3P) and nitrene upon photolysis. Further investigation of this process can contribute to building a framework for the development of additional chromophores capable of releasing two distinct reactive intermediates in a specified order.

Chemical Synthesis Of 3-Fucosyllactose, An Iimportant Human Milk Oligosaccharide
Joey Wise
Human milk oligosaccharides (HMO) are very important and the third most abundant constituent of human milk component after lactose and lipids. They are a structurally and biologically diverse class of glycans. Developing new methods for the chemical synthesis of HMO has been an active area of research. One way of synthesizing glycans in general and HMO in particular is application of thioglycoside building blocks. Many thioglycosides are known, and among these S-benzoxazolyl (SBox) found some application to the synthesis of various glycans. As a part of our ongoing efforts toward the development of novel methods for glycosylation and glycan synthesis, presented herein is our discovery that SBox donors are excellent substrates for the synthesis of HMO. That is because the SBox glycosides can be activated over other thioglycosides with excellent yield and stereoselectivity. The initial studies dedicated to the synthesis of simple glycosidic linkages and investigation of the reaction mechanism have now been extended to the streamlined synthesis of 3-fucosyllactose, a common HMO trisaccharide found in human milk.

Cooperatively-Catalyzed Koenigs-Knorr Glycosylation for Complex Glycan Synthesis
Chau Ta
Reported herein is an expansion of a recent development in glycoscience, namely the formation of glycosidic linkages under cooperatively catalyzed Koenigs-Knorr reaction conditions, to glycan synthesis. Previously, cooperatively-catalyzed Koenigs-Knorr glycosylations was a multi-step procedure that relied on the formation of a glycosyl halide intermediate with interim drying and evaporation. The optimized glycosylation can now be achieved in a single step in the presence of molecular iodine, silver sulfate, and triflic acid. This methodology has been applied to the synthesis of a novel, complex trisaccharide in a 1 + 1 + 1 fashion. Our synthetic approach comprised alternating deprotection and glycosylation steps.

Determining Bond Dissociation Enthalpies of Sulfoxides: What computational method
best predicts experimental values?
Sydney Lahm
Computational analysis was conducted to determine the bond dissociation enthalpies (BDE) of S=O bonds in eight molecules, which were subsequently compared to their experimentally derived BDEs. Computational BDE calculations were conducted utilizing various combinations of density functional theory (DFT) and basis sets. Specifically, DFT methods including M06-2X, mPW1LYP, 蠅B97X-D3, PBE0, and B3P86 were paired with basis sets def2-TZVP/J, def2-TZVP, aug-cc-pV(T+d)Z, 6-311++G(2df,2p), and def2-QZVP. The comparison between computational and experimental BDEs was evaluated through graphical representation, yielding slope and coefficient of determination (R2) metrics. Among the methods tested, mPW1LYP/aug-cc-pV(T+d)Z, PBE0/def2-TZVP, and B3P86/aug-cc-pV(T+d)Z performed best in terms of assessed metrics. Additionally, comparative analyses were expanded to include complete basis sets methods (CBS-QB3 and CBS-4m), which, exhibited comparatively lower accuracy in predicting experimentally calculated S=O BDEs compared to the combination methods.

Experimental Determination of Thermodynamic Parameters for Pseudouridine-Guanine Pairs
in Duplexed RNA: Terminal Mismatches, Tandem Pairs, and Bulge Loops
Sebastian J Arteaga, Julia W Stone, Brent M Znosko
Pseudouridine (唯), an isomer of uridine where the nucleobase is attached to the C1 of the ribose sugar via C5 rather than the standard N1, results in an additional hydrogen bond donor which can increase the stability of RNA. 唯 has been found to affect tRNA, rRNA, and snRNA function. This project aims to investigate the thermodynamic parameters of G-唯 pairs in various secondary structures to allow the incorporation of 唯 in secondary structure prediction algorithms. Data from optical melting experiments of selected oligonucleotides were analyzed to determine average 螖H藲 , 螖S藲 , 螖G藲 37, and Tm for each and compared these to their canonical counterpart. As expected, the addition of 唯 has been found to be stabilizing to a degree proportional to the number of 唯 in each sequence. These thermodynamic parameters can be used to predict likely secondary structure of RNAs containing 唯 improving RNA technology design ability.

Exploration of GPR183 Antagonist Derivatives for the Treatment of Neuropathic Pain
Olivia Farris, Elise Stuertz, Ivy Yang
Neuropathic pain presents multiple unique challenges for clinical treatment. Current treatment guidelines include prescription of tramadol, tapentadol, and other low-dose opioids. The efficacy of opioids for neuropathic pain has been called into question, along with obvious concerns regarding addiction and over-prescription. Alternatives to opioid-based treatments include neuromodulation, treatment with tricyclic antidepressants, and serotonin and norepinephrine reuptake receptors (SNRIs). While these treatments show some clinical efficacy, the lack of knowledge of their mechanisms of action has slowed the development of potentially more efficacious treatments. Thus, elucidation of the pathways involved in neuropathic pain is essential for research into the next generation of neuropathic pain treatment. Transcriptomic screening revealed that upregulation of GPR183 is pronociceptive. Oxysterol, 7伪,25-dihydroxycholesterol, an endogenous GPR183 ligand, produces such upregulation upon binding. A previously discovered inhibitor for GPR183 has been shown to reverse critical constriction injury (CCI)- induced neuropathic pain in mice. Taking advantage of the structure-activity relationship revealed by this research, selected cinnamic compounds are now being explored as part of GPR183 inhibitor derivatives that seek to produce increased bioavailability.

Exploring reverse migration in 2D and 3D environments using subcellular optogenetics
Aditya Chandu, Ajith Karunarathne, Waruna Thotamune
Cell migration is essential to the dynamic processes throughout the body such as wound healing and embryonic development. Fluid viscosity, concentration gradients, flow rate, and the presence of other cells or compounds are external factors that alongside internal factors like expression of adhesion molecules, intracellular pathways, and membrane tension, affect the cellular movement. Current literature has established that GPCRs play a unique role in cellular migration. Using typically adhered cells seeded on glass-bottomed dishes, iso-dense layers of Ficoll400 to mimic the body鈥檚 3D environment, and GPCRs coupled to light-sensitive GPCR agonists our aim is to unveil the cellular mechanisms behind reverse migration: migration away from stimuli. Advanced microscopic techniques, receptor or agonist photoactivation using confined light, and optogenetic techniques pave our way to exploring and comparing reverse migration to more conventional behavior. A deeper grasp of chemical-based reverse migration is crucial for better understanding important pathophysiological conditions, such as tumor metastasis and blood-brain barrier permeability.

Identification and Characterization of RNA Dinucleotide Bulge Sequence Families
Esha Dani
The secondary structure of RNA, which forms from intramolecular base pairing, consists of structural motifs such as bulges, hairpin loops, internal loops, etc. RNA bulges occur when one or more extra nucleotides are found on one strand of a double helical region. Dinucleotide bulges are prevalent secondary structure motifs and serve important roles in biological processes. The RNA Characterization of Secondary Structure Motifs (CoSSMos) database was used to identify dinucleotide bulges in previously solved 3D structures. Python scripts and Dissecting the Spatial Structure of RNA (DSSR) were used to annotate and compare these dinucleotide bulges. Dinucleotide bulge sequence families, different dinucleotide sequences that adopt similar 3D structures, and their structural features are reported here. These families and features can be used to improve the prediction of RNA 3D structure.

Identification and characterization of single nucleotide bulge loops in RNA
Dr. Jie Hou, Annie Jung, Dr. Brent Znosko
Despite the presence of methods that accurately determine RNA structures, they demand significant time, financial resources, and effort, rendering them inefficient for promptly solving RNA sequences. An approach to address this issue involves the utilization of computer programming to predict RNA structures from their primary sequences. Correlations found between the primary and tertiary structures of previously solved sequences would be used to predict structures of unsolved RNA sequences. When identifying these patterns, particular emphasis is placed on the tertiary structures of secondary structural motifs. Among these motifs, the investigation of structural patterns specific to single nucleotide bulge loops has received relatively less attention. Single nucleotide bulges obtained from the RNA Characterization of Secondary Structure Motifs (CoSSMos) website were clustered and characterized using Root-Mean-Square Deviation (RMSD) and Dissecting Spatial Structure of RNA (DSSR), respectively. This resulted in the characterization of 18 clusters of single nucleotide bulges with unique traits.

Isolation of DNA Aptamers That Bind Agarose Gel
Emily Falk
This study employs SELEX to isolate DNA aptamers with a high affinity for agarose. Agarose's gel-forming ability makes it valuable for drug delivery and molecular immobilization, yet its utilization without chemical modifications remains a challenge. A randomized single-stranded DNA pool is introduced to agarose gel plugs under varied binding conditions. Unbound oligonucleotides are washed away, followed by recovery, then PCR amplification of the binding sequences. The resulting aptamers demonstrate enhanced binding activity, and the isolated aptamers are reintroduced into the agarose gel plugs. Each round of SELEX enriches the pool of aptamers for those with a higher affinity for agarose. Once the desired binding activity is achieved, the aptamer pools will be further characterized to understand their specificity, affinity, and potential applications. Agarose-binding aptamers promise diverse applications in biotechnology and medicine specifically in the delivery and release of therapeutic biomolecules.

Lead (II) carbonate-alginate nanocomposite materials as contrast agents for fine vascular
MicroCT imaging
Kyan Ho
My research focuses on the synthesis of an improved nanoparticle-containing composite gel for imaging the fine vasculature of biological systems using X-ray techniques. The composite is composed of nanoparticles containing a lead carbonate phase (LNPs) distributed in an alginate hydrogel to produce a nanocomposite that gels after perfusion into the fine vasculature. LNPs are produced by an arrested precipitation process with capping provided by tetraethylene glycol, which controls nanocrystal growth and confers water dispersibility to the system. The LNPs have controllable X-ray contrast by variation of their concentration within the composite structure. Preliminary data and testing using X-ray and micro-CT imaging demonstrates that the LNPs have excellent X-ray contrast comparable to or greater than that of bone. The characteristics of the developed nanocomposite gel were shown to be improved over that of commercially available Microfil and a previously reported barium sulfate nanocomposite with a similar structure.

Phenothiazine Synthesis Through Electrochemical and Photochemical Decarboxylative
Radical Coupling Reaction Development
Travis LaPonsie
Phenothiazine-based compounds are of interest in medicinal chemistry as both antifungals and for treating mental disorders. However, in some instances generating the phenothiazine core has proven difficult, with current synthetic pathways proving unreliable or not reproducible. Developing new and efficient reactions for phenothiazine generation could allow for synthesis of a wider variety of phenothiazine cores. The goals of this research project are to expand upon the traditional reaction schemes aimed at generating phenothiazines with the addition of either electrochemistry or photochemistry. This work explores routes to C-N bond formation to form phenothiazines via two methods. One direction involves the use of electrochemistry to assist catalyst turnover in poor-yielding Buchwald couplings. The other is the use of photochemistry and copper catalysis to induce decarboxylative C-N bond formation, a route that has not been explored in phenothiazine synthesis to date.

Production of high energy density materials is an important research area with applications in many areas such as energy storage and delivery, chemical processing, and propellants. Reactive metal nanoparticles (RMNPs) are particularly useful as high energy density systems but reactivity challenges arise due to their inherent instability. We present two methods for the stabilization of RMNPs for specific applications in hydrogen production and in solid-state propellants. RMNPs were successfully passivated within the pores of metal organic frameworks (MOFs) and by capping with polyethylene. We hereby present results for RMNPs@MOF composites as hydrogen generators and polyethylene-capped RMNPs (PEN particles) as a rocket propellant material.

Structure activity relationships of core replacements in a phosphodiesterase inhibitor
for the treatment of cryptosporidiosis
Caroline Christ
Cryptosporidiosis is a diarrheal disease caused by the parasites C. parvum and C. hominis which can be life-threatening for children and immunocompromised patients. The only currently approved treatment for cryptosporidiosis, nitazoxanide, is only moderately effective in children and not effective in patients with immunodeficiencies. This study explores the role of core structure in the potency of a series of phosphodiesterase inhibitors in the Cryptosporidium parasites. By changing the heterocyclic core structure of the lead compound (鈥渃ore-hopping鈥�), the structure activity relationship can be determined and used to optimize the structure of the potential drug molecule. Inhibition of the Cryptosporidium parasites by the synthesized analogs indicates that the pyrazole core structure in lead compound 91女神-2815 may not be essential for activity and could be equally or more efficacious with an alternate core.

Synthesis and SAR Studies of the 3-position of 91女神-10482 for the Identification of
Novel Anti-Cryptosporidium Drug Analogues
Caitlin Hamill
Cryptosporidiosis is a leading waterborne infection caused by the Cryptosporidium parasite that causes diarrhea, dehydration, and malnutrition. In severe cases, the parasitic infection can result in death, most notably in young children and immunocompromised patients. Nitazoxanide is the only FDA-approved treatment, but is only modestly effective, suggesting a critical need for a new anti-Cryptosporidium drug that effectively treats all patient populations. Previous work identified triazolopyridazine MMV665917 as an analogue, which has an EC50 of 2.1 碌M. This finding led to the synthesis of 91女神-10482, an analogue with an improved EC50 of 0.070 碌M. The current work seeks to replace the 3-trifluoromethyl group on 91女神-10482 and develop structure-activity relationships (SAR) in that position. Twenty-six novel analogues were synthesized and evaluated for potency against Cryptosporidiosis, with the most potent replacement to date being the propylene 91女神-11358 analogue (EC50 = 0.56 碌M).

Synthesis of a Novel Macromolecular Drug Delivery System Based on Cyclic Galactose
Alexei Demchenko, Daniel Hoard, Anastasiia Vinogradskaia
Recent studies have shown that cyclodextrins (CD), cyclic oligosaccharides composed of linked glucose units, exhibit anti-inflammatory activity. CD possesses a hydrophobic inner cavity capable of encapsulating cancer drugs, while their hydrophilic surface increases the drug鈥檚 solubility. However, while CDs show an increase in stability, solubility, and reduced toxicity, they still have limited therapeutic effects and can cause complications. The current goal in drug delivery system development is to efficiently deliver drugs to their target binding sites, protecting them from degradation and digestion, enhancing pharmacokinetics, and enabling the crossing of biological membranes without disruption. In this study, we present a new approach for the synthesis of cyclogalactin, a cyclic carbohydrate structure containing galactose units that shows promise for pharmaceutical applications. It possesses a similar structure to CD, but its hydrophobic site significantly extends. Currently, attempts to synthesize cyclogalactin have been unsuccessful. Reported herein is our attempt to create a 6-membered galactose.

Synthesis of Novel Efflux Pump Inhibitors in the Multidrug Resistant Acinetobacter baumannii
Makaila Leask
Acinetobacter baumannii is a multidrug resistant bacterium that is largely associated with hospital-acquired infections. Multidrug efflux pumps, belonging to the Resistance-Nodulation-Division (RND) superfamily, are the major mechanisms that contribute to antibiotic resistance in bacteria. The RND pumps AdeABC and AdeIJK are the efflux pumps of interest that are responsible for the drug resistance in A. baumannii. The development of efflux pump inhibitors for A. baumannii will allow for the potentiation of antibiotics. In this research, analogs of 4,6-diaminoquoniline and benzamidines had inhibitory activity against A. baumannii efflux pumps. The best analogs had target specificity, inhibited AdeIJK efflux, and potentiated antibiotics erythromycin and novobiocin.

Probabilistic Problem: Incorporating Feedback from Emergency Managers to Improve Probabilistic
Forecast Messaging
Jack Rotter
Probabilistic forecasting is the future of forecasting from the National Oceanic and Atmospheric Administration鈥檚 (NOAA鈥檚) National Weather Service (NWS). Rather than providing a deterministic forecast to emergency managers and local decision makers, probabilistic forecasts use basic statistics to lay out a variety of possible scenarios. In addition to providing multiple scenarios, there is also more room for error in emergency managers鈥� interpretation of these forecasts. Working with NWS Fort Worth forecaster, Madi Gordon, the interpretation of graphical probabilistic forecasts by emergency managers was studied and best practices were developed for the NWS Fort Worth office. After establishing best practices at the local level, further research is being conducted at the national level with the intent of gaining further understanding of any biases emergency managers have across the United States. This, in turn, will lead to guidelines to improve graphical probabilistic forecast messaging across all NWS forecast offices.

Using Supervised Machine Learning and HYSPLIT Backwards Trajectories to Predict Airborne
VOC Concentrations
Victor Geiser
It is known that Volatile Organic Compounds (VOCs) in the atmosphere have harmful and adverse effects on human health. Recent literature suggests some VOCs may also have an effect on global radiative forcing, despite making up a very small fraction of the total atmospheric composition. Due to this, making accurate predictions of these concentrations within the context of the dynamic atmosphere is both a challenging yet imperative problem. While the fields of atmospheric chemistry and meteorology are often addressed in adjacent but related contexts, this study looks to examine the importance of meteorological variables on the concentrations of these VOCs at parts per trillion level precision, based on fully open-source meteorological data alone. Through this study it was found that although considering meteorology data alone is not enough to predict these concentrations, meteorological variables such as potential temperature, solar radiation, and mixing depth appear to have elevated importance across a standard array of meteorological variables. Moreover, this study proves that additional considerations are necessary to address the differences in data types of whole air sampling data and meteorology data when incorporated into machine learning workflows. The results of this study show that it is possible to predict airborne VOC concentrations using meteorological variables, but the accuracy of these results is currently limited by discrepancies between the spatial resolution of meteorology data and the discrete nature of whole air samples. However, given that these structural challenges exist, applying modern techniques in imbalanced regression may help address these challenges.

Graphene, a single or few layer carbon film, has been shown to have antimicrobacterial and antibacterial properties, with excellent thermal and electrical conductivity that allows for the material to be used in medical devices and implants. Here we explore direct growth of high-quality, few layered graphene on metal alloy substrates using chemical vapor deposition (CVD) and characterize its structural integrity. CVD is a scalable and controlled method of synthesis, often used in industry for large scale applications. By using CVD synthesis on FDA approved metal alloys, we can study the morphology and structural characteristics of graphene samples to investigate the most optimal growth conditions for high quality graphene with strong adhesion to its host substrate. We also discuss the design and construction of an additional smaller scale CVD system which will be dedicated predominately to high quality carbon materials growth, such as graphene and carbon nanotubes, for medically relevant applications.
