Valvular Heart Failure Is A Distinct Heart Transplant Phenotype With Comparable Adjusted Survival To Other Heart Failure Etiologies, Devon Kelley, Varun Kathawate, Joyce Ho, Andrew Belec, Takahiro Tashima, Kazuhiro Ueno, Jessica Dominic, Pavan Atluri

Division of Cardiology Faculty Papers

PURPOSE: Valvular heart failure (VHF) accounts for 1-5% of heart transplant listings. Comparative outcomes relative to other heart failure etiologies remain poorly characterized. This study defines the VHF phenotype and compares waitlist and transplant outcomes to other heart failure recipients.

METHODS: This retrospective cohort study uses the UNOS thoracic transplant database to analyze adult, first-time, heart-only listings with a diagnosis of heart disease. Patients were grouped by diagnosis as VHF or non-VHF. The primary outcome was waitlist events; post-transplant survival and outcomes were secondary analyses. Subgroup analysis was performed in the post-2018 allocation era.

RESULTS: VHF recipients were older (55.3 …

Magnetic Balancing For Microvibration Reduction In Passive Magnetic Bearings For Smallsat Reaction Wheels, Deckers Niel, Baekeland Mante, Cuypers Cedric, Seiler Rene, Vandepitte Dirk, Delabie Tjorven

Small Satellite Conference

Reduction and mitigation of microvibrations constitutes a crucial field of interest in the research of spacecraft reaction wheels. This applies all the more so in small satellites, where even minimal sources of vibrations lead to imprecision of onboard instruments. To address this, magnetic bearings offer contactless support, and thus prevent several sources of microvibrations that exist in classical ball bearings, for instance the mechanical imperfections in rolling elements. The inherently low stiffness of magnetic bearings also significantly reduces the transmitted forces in reaction wheels. Another advantage of contactless support is its potential longer lifetime because of the absence …

Delay/ Disruption Tolerant Networking In Cislunar Space, Sara Garcia-Beech, Rebecca Besser, Elizabeth Geist, Theresa Beech, Mike Palsson, Krishnan Narayanan, Ben Anderson

Small Satellite Conference

DTN (Delay/Disruption Tolerant Networking) is at foundation of NASA's LunaNet architecture, which will enable the robust communications, navigation, and networking capabilities needed to establish a long-term presence on the Moon. DTN is a network architecture composed of several different protocols that are designed to provide internetworking functionality and standardized multi-hop, end-to-end data delivery in highly stressed environments that are not optimal for traditional Internet Protocols. Bundle Protocol (BP) version 7, a store-and-forward protocol intended to run at the application layer on top of convergence layer protocols, provides the key delay tolerance functionality of DTN and is designed to handle intermittent …

Recovery Of Grus-1e From Magnetic Torquer Loss Using Data-Driven Open-Loop Attitude Steering, Nader Ganaba, Takanori Iwata, Minoru Kurata

Small Satellite Conference

In typical low Earth orbit (LEO) operations, the inability to remove excess angular momentum often leads to the decommissioning of a satellite. This paper presents the on-orbit recovery of GRUS-1E, a hundred kg class Earth observation satellite in Axelspace Corporation’s GRUS-1 constellation. The recovery followed the permanent loss of magnetic torquer commanding capability, which in turn disabled the satellite’s nominal reaction wheel momentum unloading. In addition, the satellite experienced persistent disturbance torques that significantly exceeded the combined contributions predicted by standard models, including gravity gradient, solar radiation pressure, aerodynamic drag, and the estimated residual magnetic dipole moment. The magnitude of …

Towards Designing And Performing Biological Sex: Explorations Of The Cyborg And The Inanimate, Beja Puskas

Theatre and Dance Honors Projects

While gender has been largely debunked as a form of performance, biological sex remains an irreducible point of departure. This essay challenges biological sex as a category through the Foucauldian lens of bio-power and technologies of the self. It merges findings from interviews surrounding intersectionally marginalized experiences with menstruation with trans and disability studies. Utilizing Mel Chen’s theory of animacies, and Margrit Shildrick’s human-technology amalgamation theory, this essay blurs the biological-artificial binary. While there are obstacles, limiting what is biologically possible for humans, the body can be significantly augmented through imagination, body modification, and the invention of newly gendered practices.

Unboxing Relations: An Ethnographic Study Of Blind Box Consumption In The U.S., Wendy Zheng

Sociology Honors Projects

Blind box consumption is a format for purchasing packaged toys without knowing the specific item in advance. It has become a global trend and is often viewed as irrational or gambling-like behavior in past literature. Drawing on ethnographic observations and interviews conducted in retail settings, this study examines how consumers make sense of uncertainty through social interaction. This study proposes a two-layer model of consumption. In the first layer, social interaction during the consumption process helps consumers negotiate risk, generate meaning, and become more skilled buyers. In the second layer, consumers engage in moral and value judgments that involve distancing …

Disksat: On-Orbit Performance And Lessons Learned From The Inaugural Flight Of Two-Dimensional Satellites, Darren Rowen, Catherine Venturini, Garrett Kinum, Brian Hardy, Joseph Gangestad, Lisa Toda, Chris Day, Thomas Pridy, Eddson Alcid, Ziba Shahriary

Small Satellite Conference

DiskSat is a novel spacecraft design that uses a disk-shaped form factor, 1 meter in diameter but only 2.5 cm in depth, to provide unprecedented power-to-mass ratio in a nanosatellite and the potential to operate long-term in very low Earth orbit (VLEO). The inaugural flight of four DiskSats launched on 18 December 2025 from NASA’s Wallops Flight Facility on an Electron rocket, which delivered the satellites to a 550-km altitude orbit at an inclination of 45 deg. Developing DiskSat’s two-dimensional form factor presented a myriad of challenges for power generation, thermal management, attitude control, and deployment that could only be …

Unsustainable Stories: Agricultural Knowledge On The Great Plains, 1880-1934, Philomena Shuffelton-Sobe

History Honors Projects

This thesis explores stories about how people farmed and learned about farming on the Great Plains from 1880-1920 through three inter-connected narratives: the Allotment system, agricultural education programs at federal Indian Boarding Schools, and the rapid rise and fall of the Dry Farming movement. These systems were built on stories about how people should live with and on the land that promoted unsustainable, destructive ways of farming and knowledge production. This scholarship places Assimilation Era agricultural education for Native and non-Native farmers within the context of the increasing reliance on systems and science and the institutionalization of agricultural knowledge.

Somewhere Far And Somewhere Near: A Short Story Collection, Jizelle Villegas

English Honors Projects

Somewhere Far and Somewhere Near is a short story collection that positions body horror, “where corporeality constitutes the main site of fear, anxiety and disgust,” alongside Gloria Anzaldúa’s concept of la facultad, or “see[ing] deeper realities within surface phenomena,” which is heightened in the Latina body. Stories range from depicting realistic body horror like cancer and disordered eating to the grotesque and supernatural, like spirits and vampires. I draw on Latina speculative fiction writers, Tejana scholars and my own lived experiences to explore how location and identity presses upon the emotional and psychological stakes of my Latina characters

Systemic Progress Regeneration Protocol (Sprp), Volodymyr Kotegov

Defensive Publications Series

This protocol defines the mandatory rules for the creation, evaluation, acceptance, and long-term stewardship of engineering work by parties that voluntarily adopt it.

The protocol exists to counteract a fundamental process: the spontaneous decay of civilizationally critical engineering knowledge. Its objective is not the production of superior individual artifacts. Its objective is the sustained growth of the survivable mass of engineering knowledge — the quantity of knowledge that remains comprehensible, reproducible, and extensible after complete institutional rupture, generational turnover, and loss of external infrastructure.

The protocol claims no universal authority. It applies only to nodes and Inheritance Lines that have …

Brief Of Amici Curiae Scholars For The Advancement Of Children’S Constitutional Rights In Support Of Respondents: St. Mary Catholic Parish V. Roy, Catherine Smith, Tanya Washington, Robin Walker Sterling, Suzette Malveaux, Barbara Bennett Woodhouse, Sara S. Hildebrand, Abigail L. Fleming, Jeremiah Chin

Scholarly Articles

This Court should consider those most directly impacted by the decision in this case: the intended beneficiaries of Colorado’s Universal Preschool Program (“UPK”), Colorado’s children. To paraphrase Shakespeare, though they be but little, they are constitutional rights-bearers and are thus entitled to be free from state-funded discrimination.

Amici are scholars of children and the law, education law, family law, and anti-discrimination law. Amici draw this Court’s attention to the significant harms children in the LGBT community would bear should Colorado be compelled to allow state-funded religious schools to discriminate against preschoolers. Exempting religious schools from the State’s equal-opportunity and antidiscrimination …

The Role Of Seed Mix Characteristics And Soil Amendments During Post-Agricultural Prairie Restoration, Valerie N. Thurston, Michaela J. Woods, Madelaine Gregory, Mary C. Lloyd, Ryan W. Mcewan

Biology Faculty Publications

Introduction: Prairie restoration on degraded lands may be influenced by seed mix characteristics, including species richness and legume establishment. Soil amendments may facilitate restoration; however, the practical usefulness of techniques such as applications of whole soil and leaf mulch remains relatively unclear.

Objectives: We assessed whether increasing species richness and legume content in seed mixes enhances prairie restoration success and examined how soil amendments interact with seed mix composition to influence cover, species richness, diversity, and legume establishment.

Methods: We conducted a field experiment on a 12-ha post-agricultural site in Ohio, U.S.A. Twenty 50 × 50 m plots received one …

Trade Measures—Relationships And Implications, Peijie Wang, Zhiyuan Liu

Plymouth Business School

Various value-added trade measures have been developed to address the concern in the growing volume of trade in intermediates that are double counted when crossing international borders more than once. This paper raises a query and makes an inquiry into the query. How trade figures in these measures would look like if comparisons are made in net terms and in the context of trading with the rest of the world, given that some double counted elements offset themselves in a series of crossing border processes in opposite traffic? Examined among them in this study are domestic value added in gross …

Hydrogels For Local Drug Delivery In Biofilm-Associated Periprosthetic Joint Infection: Current Progress And Future Directions, Karolina Kraus, Pawel Mikziński, Bindu Subhadra, Emil Paluch

Faculty Publications - Biological Sciences

Periprosthetic joint infection (PJI) remains one of the most serious complications of arthroplasty, largely due to the formation of microbial biofilms on implant surfaces. Biofilm-associated infections exhibit increased tolerance to antimicrobial therapy and host immune responses, making eradication difficult and often requiring repeated surgical interventions. Consequently, there is a growing need for effective local therapeutic strategies capable of delivering high concentrations of antimicrobial agents directly to the site of infection while minimizing systemic toxicity. Hydrogels have emerged as promising drug delivery platforms for the management of biofilm-associated PJI. Their biocompatibility, injectability, high water content, and tunable physicochemical properties enable controlled …

Advanced Ai Deployment On Smallsats: A Mixed Precision Approach To Onboard Perception And Fpga-Gated Inference, Margaret Michelsen, Jackson Gardner, Shawn Jones, Jackson Kulik, Mario Harper

Small Satellite Conference

MOTIVATION:

SmallSats are asked to make time-sensitive calls (vessel detection, cloud filtering, debris tracking) but CubeSat-class compute is starved for power, memory, and radiation-tolerant silicon.

Most missions still downlink raw imagery for ground processing, costing hours-to-days of latency and scarce bandwidth. Running inference onboard means solving two separate problems:

• When to run inference: compute and power budgets can’t tolerate a neural network firing on every frame.
• Whether it fits when it does run: the model has to live inside a memory and compute envelope measured in megabytes, not gigabytes.
