Chimica et Natura Acta

Type 2 diabetes mellitus continues to rise and calls for safe therapeutic leads. This study assessed the potential of triterpenoids from bitter melon (Momordica charantia) as AMP-activated protein kinase (AMPK) ligands at the ATP-binding site through an in silico approach. AMPK (PDB ID: 4QFG) was prepared in YASARA; nine M. charantia triterpenoids and metformin were docked in PLANTS. Redocking of staurosporine validated the protocol (RMSD 0.2376 Å; ≤2.0 Å). Kuguacin J (-89.9934), Karavilagenin B ( 86.4084), and Kuguacin R (-85.8514) yielded lower (more favorable) docking scores than metformin (-56.5325) and interacted with hinge residues (Val96 and Glu94/Glu100). As expected, the …

From Himalayan Catastrophe To National Resilience: Lessons From The 2026 Bhote Koshi And Trishuli River Floods In Nepal, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

On the morning of 26 August 2026, the mountains above Nepal’s northern frontier delivered a disaster of almost unimaginable speed and scale. A massive mass of ice, rock, and sediment detached in the high Himalayan terrain near the Nepal–Tibet border, descended roughly 1,200 metres, interacted with the Lhende Khola system, and generated a debris-rich flood that surged through the Bhote Koshi and Trishuli river corridors, destroying settlements, markets, roads, bridges, hydropower facilities, and an international border crossing and transforming them into fields of mud, boulders, and wreckage within minutes (ICIMOD, 2026b; Reuters, 2026a). Satellite analysis indicates that a substantial section …

Sla Elastic Resin Curing Test Data, Richard Amesimenu, Johnson Nwogu, Haijun Gong

Faculty Datasets

3D printing via stereolithography (SLA) enables high-resolution polymer components, but as-printed parts may exhibit incomplete polymerization and reduced mechanical performance. This study investigates the effects of UV post-curing time on SLA-printed elastic photopolymer resin. Specimens were evaluated using Differential Scanning Calorimetry (DSC), uniaxial tensile testing (ASTM D412 Type C), and Durometer Type M hardness testing. Results show that increased post-curing enhances crosslink density, tensile strength, elastic modulus, and hardness, while extended curing may reduce ductility. An optimal post-curing window balancing stiffness and flexibility was identified. Testing datasets include DSC (dsc/), tensile testing (tensile/), and hardness testing (hardness/) results for uncured …


From Retrieval To Generation: Building And Evaluating An Ai Accompanist For Piano Duets With An Anticipatory Music Transformer, Sai Ruthvik Uppala Sep 2026

From Retrieval To Generation: Building And Evaluating An Ai Accompanist For Piano Duets With An Anticipatory Music Transformer, Sai Ruthvik Uppala

Masters Theses

Systems that accompany a live musician, such as ACCompanion, work by retrieval: they hold a written accompaniment and stretch its timing to follow the soloist, so they can only accompany music whose second part already exists as a score. This thesis asks whether that second part can instead be generated, and specifically whether a machine learning model can write an accompaniment for a piece whose score it has never seen. A player performs the primo, the melody; a model produces the secondo, the accompaniment; and a score follower places the generated notes against the live performance. If this works, a …

Studying Electromagnetic Wave Scattering From Small Dielectric Particles Using Neural Networks, Bryan Taylan, Patrick Corzo, Chris Velissaris, Theodoros Panagiotakopoulos

Undergraduate Scholarship and Creative Works

Physics-informed neural networks solve the Helmholtz equation without labeled data, but a low residual alone does not confirm that a solution preserves the physical distinction a downstream task depends on. We trained a four-layer SIREN with physics-based residuals, a Sommerfeld condition, Adam, and L-BFGS, modeling a Gaussian source and a plane wave scattering from a small dielectric inclusion. Fine-tuning from four base models produced 600 complex fields spanning omega = 4 to 20. A compact CNN, three ResNet-18 variants, and a frozen OpenCLIP encoder classified these fields under five random seeds. The CNN achieved (95.65 +/- 0.77)% accuracy, outperforming OpenCLIP …

Publications and Research

Transdermal delivery of high-molecular-weight proteins is challenging because of their large molecular size and hydrophilicity, and the barrier properties of the stratum corneum. We report a hydrated ionic liquid-in-oil (HIL/O) microemulsion for transdermal delivery of high-molecular-weight proteins. A biocompatible ionic liquid (IL) composed of cholinium cation and propionate anion, optimized at 45 wt% hydration, was developed as a protein-compatible solubilization medium that dissolved ovalbumin (molecular mass ∼ 45 kDa) and bovine serum albumin (molecular mass ∼ 66 kDa), whereas lower hydration levels were insufficient for effective protein dissolution. Following solubilization, circular dichroism spectroscopy showed recovery of the native-like secondary structures …

The Baltic Bear Trap Wargame, Connor Crookham

Space and Defense

Modern military education increasingly relies on experiential tools that allow students to explore the complexity of contemporary conflict in ways that lectures and readings alone cannot achieve. Nowhere is this more evident than in the emerging emphasis on multi-domain operations, integrated deterrence, and the blurred boundaries between competition and armed conflict. The Baltic Bear Trap wargame was developed as a student design project to meet this instructional need, offering a structured environment in which players must think, plan, and act as operational-level decision makers confronting a deteriorating security situation in the Nordic–Baltic region. Built for use at the Swedish Defense …

Cislunar space—the region between Earth’s geosynchronous orbit (about 36,000 kilometers from Earth) and the Moon (roughly 384,000 kilometers away)—is becoming a critical frontier for future space exploration and commercialization.1 This zone includes the Moon’s orbit, transfer orbits, and the Earth-Moon Lagrange points. Additionally, as more nations and corporations launch lunar missions and establish long-term infrastructure, cislunar space is increasingly becoming a strategic focus for exploration, logistics, and transportation.


Planetary Defense As The Ethico-Legal Gateway For International Space Security, Evie Kendal Sep 2026

Planetary Defense As The Ethico-Legal Gateway For International Space Security, Evie Kendal

Space and Defense

Following the news in late 2024 that there was a city-killer asteroid on a possible collision course with Earth, many members of the public were shocked to learn there was no reliable global plan for managing such asteroidal and cometary impact hazards. While calculations of Asteroid 2024 YR4’s trajectory were further refined to exclude the previously reported 2-3% chance of collision in 2032, this event highlighted a major security threat: the lack of a globally coordinated, appropriately resourced, and politically supported planetary defense strategy (Gibney, 2025). In so doing, it also provided an opportunity for security experts to consider the …


Space-Based Missile Defense With Early Interceptor Launch Strategies, William Priedhorsky, James Wells Sep 2026

Space-Based Missile Defense With Early Interceptor Launch Strategies, William Priedhorsky, James Wells

Space and Defense

There is renewed interest in space-based boost-phase intercept (SBPI) for missile defense against ICBMs of near-peer adversaries. We discuss SBPI in the context of other missile defense approaches, and address one of its challenges, which is the expense of fielding a large enough constellation of interceptors in space to counter even a small number of ICBMs. We develop an early-launch approach that could substantively reduce the required density of interceptors. Because every second matters in boost-phase defense, early launch of interceptors can significantly increase the reach of each interceptor. Early launch would require interceptors that have highly throttleable motors. Our …

Golden Dome: Seeking Space Security, Namrata Goswami

Space and Defense

The “Golden Dome” initiative [formerly Iron Dome] was announced by President Donald Trump on January 27, 2025, signifying a transformative shift in global space security policy. It fundamentally questions long-standing assumptions about deterrence, national vulnerability to missile attacks, and the role of space in strategic defense. More importantly, it emerges at a moment of acute strategic transition: the erosion of Cold War arms control frameworks, the rapid advancement of hypersonic and orbital delivery systems, and the growing integration of space into warfighting doctrines. Launched via a presidential memorandum in January 2025, Golden Dome calls for a layered missile defense system …

Individualized Bayesian Inference Identifies Novel Genetic Variants For Parkinson's Disease, Jin Ren, Yasaman J. Soofi, Md Asad Rahman, Qing Lu, Jinling Liu

Engineering Management and Systems Engineering Faculty Research & Creative Works

Parkinson's disease (PD) is a complex neurodegenerative disorder with a significant genetic component. While genome-wide association studies (GWAS) have been instrumental in identifying genetic variants associated with PD, the reliance on large sample sizes and population-level analyses may overlook variants with lower minor allele frequencies or individual-specific relevance. Individualized Bayesian Inference (IBI) offers a promising method to complement GWAS by identifying and prioritizing candidate genetic markers at both the individual and patients-like-me subgroup levels. This study evaluates the application of IBI to PD genetics, using GWAS as a baseline for comparison. We analyzed genetic data from the Fox Insight online …

Thermal And Electrical Properties Of (Cr,Mo,Ta,V,W)C High-Entropy Carbide Ceramics, Ali Sarikhani, Steven M. Smith, Suzana Filipovic, William G. Fahrenholtz, Gregory E. Hilmas

Materials Science and Engineering Faculty Research & Creative Works

The synthesis and characterization along with the resulting properties of fully dense (Cr,Mo,Ta,V,W)C high entropy carbide ceramics were studied. The ceramics were synthesized from metal oxide and carbon powders by carbothermal reduction, followed by spark plasma sintering at various temperatures for densification. Increasing the densification temperature resulted in grain growth and an increase in the lattice parameter. Thermal diffusivity increased linearly with testing temperature, resulting in thermal conductivity values ranging from ∼7 W/m•K at room temperature to ∼12 W/m•K at 200 °C. Measured heat capacity values matched theoretical estimates calculated using the Neumann-Kopp rule. Room temperature electrical resistivity decreased from …
