Distal Adding-On As A Complication Of Posterior Spinal Fusion In Adolescent Idiopathic Scoliosis: A Scoping Review Of Contemporary Evidence, Hussein Hashem, Hassan Abou Adma, Joseph Hayek, Ali Rezazadeh Shirazi, Karim Gaber, Waleed Kishta

Western Journal of Orthopaedics

Distal adding-on (DAO) is a complication of spinal fusion characterized by postoperative deformity progression distal to the fusion construct. DAO after posterior spinal fusion for adolescent idiopathic scoliosis (AIS) is variably defined and inconsistently managed. This scoping review synthesizes evidence on DAO detection, management, and outcomes. A PRISMA-ScR–guided search identified relevant studies. Thirty-one studies (2,998 patients; median follow-up, 30 months) met inclusion criteria. Reported DAO incidence ranged from 3.5% to 62.5%, reflecting heterogeneity in definitions, patient factors, surgical constructs, and follow-up duration. Revision surgery was infrequent and typically delayed. When performed, it was most often prompted by progressive coronal decompensation …

A Historical Analysis Of The Squatter Settlements (Sukumbasi) In Nepal And The Role Of Smart Settlements, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

In Nepal, landless populations can broadly be categorized into two groups: urban squatters and rural landless families. Each group can further be distinguished by its level of political connection and access to power.

Among urban squatters, politically connected groups often occupy open public spaces in cities with some degree of protection or tolerance from political parties. In contrast, less powerful urban squatters usually settle on public land because they cannot afford formal housing. These settlements are commonly located in unsafe or marginal areas, such as riverbanks, flood-prone zones, and unused public spaces. Despite these risks, many remain in urban areas …

Acoustic Black Hole Structures Using 3d-Printed Polymer Concrete, Siham S. Al Shanti

Civil Engineering ETDs

Mitigating unwanted vibrations is essential in the design of structural and mechanical systems to ensure safety, reliability, and long-term performance. This dissertation advances the Acoustic Black Hole (ABH) concept, passive vibration control strategy, by replacing geometric tapering with controlled material properties. Using Euler–Bernoulli beam theory, elastic modulus variation in polymer concrete (PC) enabled wave velocity reduction without compromising fatigue resistance. The high strength, excellent damping, and rheological properties of PC makes it ideal for 3D-printed ABH structures. This work examined bond performance between normal concrete properties, developed PC mixes with tailored rheological and mechanical properties, and evaluated their 3D-printability. A …

Puf-Based Digital Money With Propagation-Of-Provenance And Offline Transfers Between Two Parties, Benjamin Bean, Cyrus Minwalla, Eirini Eleni Tsiropoulou, Jim Plusquellic

Electrical and Computer Engineering ETDs

Building on prior concepts of electronic money (eCash), we introduce a digital currency where a physical unclonable function (PUF) engenders devices with the twin properties of being verifiably enrolled as a member of a legitimate set of eCash devices and possessing of a hardware-based root-of-trust. A hardware-obfuscated secure enclave (HOSE) is proposed as a means of enabling a PUF-based propagation-of-provenance (POP) mechanism, which allows eCash tokens (eCt) to be securely signed and validated by recipients without incurring any third party dependencies at transfer time. The POP scheme establishes a chain of custody starting with token creation, extending through multiple bilateral …

The Sexual Assault And Violence Experiences Questionnaire: Community-Developed Items For Gathering Sexual Violence Histories With Displaced Women, Meredith A. Blackwell

Psychology ETDs

Improving measurement of sexual violence has contributed to major policy changes in the United States. However, research on sexual violence largely overlooks those exposed to conflict and displacement: a population especially at risk. Assessment measures often ignore contextual features and use phrasing that is vulnerable to underreporting. This community-based participatory research project collaborated with cultural experts from Mexico/Central America and Afghanistan to develop a preliminary item list for a self-report measure of prior sexual violence. Analysis of focus group data from 30 women revealed a range of sexual violence experiences, and provided critical phrasing used to form an item list …

Fedchae: Federated Learning With Client Clustering And Hybrid Adaptive Engagement, Chaeeun Park

Electrical and Computer Engineering ETDs

As machine learning adoption expands, data privacy concerns have grown significantly. Federated Learning (FL) addresses this challenge by allowing clients to train locally and share only their model parameters with the server. However, conventional FL methods such as FedAvg suffer from high communication overhead, as all clients must participate in every global round.

This paper proposes FedChae (Federated Learning with Client Clustering and Hybrid Adaptive Engagement) to balance communication efficiency and model accuracy. FedChae alternates between Grouping Rounds, where all clients perform clustering, and Conventional Rounds, where one client per cluster updates the model.

Simulations with 100 clients using Multi-class …

How To Talk To A Seahorse: Communication In Transmasculine Gestational Experiences As Told Through Narrative, Emerson Armstrong

Communication ETDs

Transmasculine experiences before, during, and after pregnancy were evaluated using focus groups and autoethnographic research. As transgender people are more likely to experience inequality in healthcare encounters, this project aims to shed light on, and counter sensationalized accounts of male pregnancy, as transmasculine gestational individuals sought normalization in their experiences of pregnancy. Seven focus groups consisted of 90 minute sessions, with a total of 15 participants. Transcripts were analyzed using a trans narrative approach to find a greater understanding about identity construction, challenges, and changes around trans pregnancy. Asking about communities and healthcare experiences worked to create a complete picture …

From Energy Abundance To Blackouts: Political Explanations For Ecuador’S 2024 Electricity Crisis, Selene V. E. Diaz Martinez

Political Science ETDs

Ecuador’s growing reliance on hydropower has positioned it as a regional leader in renewable energy development. However, recent droughts have exposed the vulnerability of this energy model in the face of climate change. In 2024, widespread blackouts underscored the risks of overdependence on hydroelectricity in the country. The media suggested that the cause of the blackouts was due to an abnormal drought that year. However, climate change alone cannot explain the lack of use of other generation sources to meet demand. suggesting that a review of political choices could provide insight into the sector's failure. This research examines the political …

Kakeya Sets Over The Heisenberg Group, Gabriel Jacob Gress

Mathematics & Statistics ETDs

The Hausdorff dimension of Kakeya sets is an interesting problem where the two-dimensional case can be proven directly, but even obtaining bounds on the higher dimension analogues can require highly technical machinery. The difficulty of the general case has inspired analysts to look at Kakeya sets from non-Euclidean viewpoints.

In this paper, we explore a construction of the Kakeya set in the first Heisenberg group H^1. By utilizing the sub-Riemannian manifold of H^1 we can apply tools in geometric measure theory which at this time cannot be applied in R^3. We restate and provide a detailed proof for a sharp …

On Sharpest Tail Bounds For Functions Of Tail Bounded Random Variables, Stephen Harrison

Mathematics & Statistics ETDs

Consider n real/complex, independent/dependent random variables with respective tail bounds and g a measurable function of the r.v.’s. Consider f the “sharpest” tail bound of g (sharpest in the sense, if f were any less, then for some X1, ..., Xn satisfying the conditions, g(X1, ..., Xn) would not satisfy the tail f). Significant research has been done to approximate f often with high accuracy. These results are often of the form, for g in this family, and tail bounds of Xk in this family, f is bounded by some f′ with high accuracy. However, the question “what would it …

Dense Temporary Array Investigation Of Jemez Uplift Seismicity, Jillian D. Podmore

Earth and Planetary Sciences ETDs

A protracted multi-stage tectonic and magmatic evolution combined with low regional crustal strain rates make it challenging to characterize active structure that may host earthquakes in the Jemez Mountains of New Mexico. Here, we leverage temporary 1-month deployments of nodal seismometers to gain new insights into seismicity of the Jemez Mountains, which only have continuous seismic monitoring on their eastern flank as a result of the Los Alamos Seismic Network. Our catalog is built using 4 steps: phase picking in continuous seismic data, association of picks to detect unique events, event magnitude estimation, and absolute hypocenter estimation. We detect and …

Application Of Bimetallic Transition Metal Oxides Electrocatalysts For Li-Co2 Batteries And Li-O2 Batteries, Jianda Wang

Chemical and Biological Engineering ETDs

Li-ion batteries are the dominant commercial rechargeable batteries nowadays, which are used in electronic devices and electrified transportation widely. However, undesirable energy density of Li-ion batteries prohibits them from meeting requirements of new generation electronic devices. Therefore, it is important to find more alternative electronic energy storage systems with higher capacity. Fortunately, Li-CO2 batteries, featured high capacity and ability to convert CO2, have become a promising candidate to replace Li-ion batteries. In addition, Li-O2 batteries also attract people’s attention due to their high energy density and low cost. However, Li-CO2 batteries and Li-O2 batteries both face challenges of terrible cycle …

Thermally Stable And Regenerable Catalysts For Alkane Dehydrogenation, Ryan Alcala

Chemical and Biological Engineering ETDs

Shale gas upgrading reactions have gained much interest since production dramatically increased around 2010. These reactions occur at high temperatures (600°C +) where undesired processes like sintering and/or coking often occur. It is of interest to use materials like ceria as a catalyst support in these alkane conversion reactions, but ceria is prone to losing active surface area through sintering. It is also of interest to understand the behavior of PtMn and PtZn intermetallics for propane dehydrogenation as they have been identified as some of the best catalysts by theory-based prediction in literature. This manuscript explores ways of utilizing ceria’s …

Neurobehavioral Mechanisms Of Psychotic-Like Experiences And Cannabis Use, Ethan Campbell

Psychology ETDs

As cannabis use has increased steadily over the past decade, there is critical need to evaluate early cannabis use as a potential risk factor for the development of psychosis. Neurobehavioral mechanisms underlying novelty salience could clarify how cannabis exposure may influence subclinical psychotic-like experiences (PLEs). The present study leveraged dynamic functional connectivity and task-fMRI to assess the role of novelty processing in cannabis use and PLEs. A group of brain regions dynamically tied to the salience network while viewing short films were found to increase their activation as a function of stimulus novelty during a novelty bandit task. PLEs were …

Contemporary Martian Geomorphic Processes And The Suitability Characterization Of Terrestrial Analogues, Daniel Paul Mason
