The Occurence Of Expansive Clay Soils In Illinois And Their Effects On Shallow Lightly Loaded Foundations, Greg James Gollaher Jan 2026

The Occurence Of Expansive Clay Soils In Illinois And Their Effects On Shallow Lightly Loaded Foundations, Greg James Gollaher

Masters Theses

"The damage caused to shallow foundations and slabs on grade by the shrink-swell activity of clay soils is well documented across the United States. There are local and national resources available that delineate areas that are problematic and areas that are not. These resources paint Illinois as an undemanding foundation environment. However, our experience differs from this. Our experience tells us that damage related to the shrink-swell activity of clay soils is widespread, and commonly severe causing not only cosmetic damage to structures and hard improvements but also affecting the serviceability and longevity of structures.

Acute Correction Of Acquired Genu Valgum Secondary To Post-Traumatic Growth Arrest At The Time Of Distal Femur Fracture., Josiah Wolf, Nicholas Pelz, Adam Mansour, Christopher Iobst, Allen Kadado

Surgery Articles

A 14-year-old male patient sustained a distal femur fracture after a ground-level fall. His history was notable for severe acquired genu valgum secondary to a childhood lawnmower accident, which had required multiple limb salvage procedures including a Syme amputation and soft-tissue skin grafting. Acute correction of the limb deformity was performed concurrently with fracture fixation using a retrograde intramedullary nail and poller blocking screws. Retrograde intramedullary nailing represents a viable treatment option for simultaneous acute correction of acquired genu valgum and stabilization of distal femur fractures.

A Universal Hybrid Model-Free Deep Quantum–Transfer Learning Controller Enhanced By Grey Wolf Optimization For Dc–Dc Boost Converters With Hardware-In-Loop Validation, Seyyed Morteza Ghamari, Asma Aziz

Research outputs 2022 to 2026

This paper proposes a universal hybrid model-free quantum–transfer learning controller with enhanced online grey wolf optimization algorithm (GWO–QTL) for DC–DC boost converter. This system has the characteristics of non-minimum phase behavior, parasitic effects, and fractional-order dynamics because of high frequency operation. These characteristics make analytical modeling complicated and make it difficult to have a single traditional controller that will operate reliably over different converter types. This motivates the creation of a unified model-free control framework that is able to learn directly from the behavior of the converter without relying on the topology specific models. Reinforcement learning, where an agent interacts …

Customer Participation In Service Recovery: Accounting For The Role Of Customers’ Perceived Control And Empowerment In Hotel Services, Aron O'Cass, Shahin Sharifi, Vida Siahtiri, Atefeh Saniee

Research outputs 2022 to 2026

Customer participation in service recovery is common, yet little is known about how different participation roles shape recovery evaluations. This gap is especially salient in hotels, where recovery often unfolds under time pressure and heightened emotions. We conceptualize participatory service recovery as involving two distinct customer roles: solution identification and solution implementation. Across three studies, we examine how these roles shape recovery satisfaction and whether perceived control and psychological empowerment help shape these effects. Study 1 uses the critical incident technique to identify role-specific participation behaviours and customers' interpretations of their recovery involvement. Studies 2 and 3 use scenario-based experiments …

Development Of A Clinical Prediction Model To Guide The Selective Use Of Spect/Ct In Papillary Thyroid Cancer, Liya Zhu, Junik Son, Lu Wang, Haifeng Hou, Byeong Cheol Ahn

Research outputs 2022 to 2026

Background: Radioiodine whole-body scan (WBS) is routinely performed after radioiodine therapy in papillary thyroid cancer (PTC), but its two-dimensional nature limits anatomical localization. The addition of single-photon emission computed tomography/computed tomography (SPECT/CT) improves diagnostic accuracy; however, routine use exposes patients to additional radiation, longer imaging time, and higher costs. This study aimed to establish a predictive model to identify which patients with PTC are more likely to benefit by adding SPECT/CT imaging after WBS, enabling selective rather than routine use. Methods: This retrospective study included 265 patients with pathologically confirmed PTC who underwent postoperative radioiodine therapy followed by WBS and …

Clinical liquid biopsy (e.g., blood or urine) specimens, as a minimally invasive source of crucial molecular information, continue to grow in importance for efficacious targeted cancer treatment. Yet, current molecular profiling technologies are still confined to centralized laboratory testing, which escalates testing costs, result turnaround time, and patient anxiety. Crucially, there is also a scarcity of purposeful clinical validation studies to rigorously evaluate emerging liquid biopsy technologies from research settings to facilitate clinical translation. Here, we report liquid biopsy biosensor advancements in achieving rapid, accurate, and decentralized molecular profiling of a clinically accredited prostate cancer (PCa) urinary circulating RNA biomarker …
