Faculty, Staff and Students Publications

Medulloblastoma (MB) is the most common malignant pediatric brain tumor, and Group 3 (G3, MYC-driven) MB has the worst prognosis. Despite advances in molecular classification, oncogenic drivers of G3 MB remain poorly defined. To identify such drivers, we profiled transcription factor expression across MB subgroups. Our analysis revealed Ras-responsive element binding protein 1 (RREB1) as one of the most highly expressed transcription factors in G3 MB. RREB1 knockdown impaired cell proliferation in vitro and prolonged survival in orthotopic xenograft models, suggesting it plays a key role in regulating tumor growth. Mechanistically, RREB1 acts by enhancing transcription of TGF-β pathway genes. …

Varieties And Domains: A Syncretic Synthesis Of Law And Justice In India ( Including A Special Emphasis On Alternate Dispute Resolution), Amrith Bhargav B

Theses and Dissertations

From the abstract idea of Dharma that enabled the practice and sustenance of local custom and usage, law was defined without verbiage but in meanings and understandings. In the colonial age, law was constantly being defined and codified not just textually, but through projects of economies of politics, knowledge and power in a way that their transactional metrics produced social and cultural genres that changed India forever. In that state of play, lawyers and their associated players contributed to the emerging culture of power and dominance with their tool of making the law through cases and mainstreamed the colonial legal …

Targeted Delivery Of Rapamycin Via Epidermal Growth Factor Receptors In Pancreatic Cancer Cells Inhibits Cell Proliferation And Induces Apoptosis, Nawab Ali, Adeolu S. Oluremi, Christopher Baldwin, Nickolas Gustavison, Mujeebat Bashiru, Adeniyi Oyebade, Noureen Siraj, Raj Raghavendra Rao

Faculty Scholarship

Pancreatic cancer (PC) is aggressive and deadly; most PC cells overexpress an epidermal growth factor receptor (EGFR). EGFR-targeting peptide (GE11) was conjugated to gold nanoparticles (AuNPs) for delivering rapamycin (Rap), an mTOR inhibitor that reduces proliferation and induces apoptosis. Biophysical techniques confirmed the conjugation. Rap loading efficiency was 41.5%, with sustained release at a lower pH. Conjugates showed higher uptake in PANC-1 cells than unmodified AuNPs. It also inhibited proliferation and induced apoptosis via pathways involving reactive oxygen species, mitochondrial damage, and caspase activation. This approach represents a promising nanoparticle-based therapeutic strategy targeting PC cells, utilizing GE11-EGFR interactions to minimize …

The transportation sector plays a vital role in facilitating human well-being by moving people and goods. In Iraq, the sector faces significant challenges, including an annual fuel loss of up to 500 billion dinars and substantial fuel wastage. Each vehicle consumes approximately 570 liters of gasoline annually due to traffic congestion, as the number of vehicles at peak times is estimated per kilometer of the three-lane street (1,059 cars km/h). In contrast, their number is estimated at regular times (450 cars km/h), leading to increased greenhouse gas emissions from fuel combustion used to operate vehicle engines. The current study analyzed …

Solving Hierarchical Variational Inequality For Almost Mean Nonexpansive Mappings, Noor Saddam Taresh, Salwa Salman Abed

Baghdad Science Journal

A clear common method in solving some types of nonlinear problems is to exchange the original problem with a collection of regularized problems and all these regularized problems have exactly one solution. A particular solution of the original problem will be obtained as a limit of these unique solutions of the regularized problems. This idea is used to provide a method for the hierarchical fixed point approach to solving variational inequality problems (VIPs). In this work, we intend to study two new iterative schemes by examining their strong convergence to a common fixed point for mappings defined for a nonempty …

Comparing And Evaluating Contralateral Breast Dose Relative To Median Ptv Tumor Bed Dose For Hypo-Fractionated Breast Treatments Using Import High Dose Constraints., Shannon J. Nordby

Masters Projects

This study is aimed to compare two different planning constraints for post-lumpectomy whole breast radiation treatments to evaluate whether or not the mean dose to the contralateral breast can be significantly reduced while maintaining plan quality for treatment. A total of 10 patients who had first undergone a lumpectomy were included into this study. Each patient’s initial treatment plan was created using a conventional approach with a mean dose constraint of < 600 cGy (Plan A) and then was replanned using the Import High protocol of a mean dose constraint, aiming to further push for a mean dose < 150 cGy (Plan B) to the contralateral breast. Both of these plans were analyzed for PTV coverage and dose to the surrounding critical structures. The results have shown that the contralateral mean dose was significantly reduced from an average of 216.32 in Plan A to 126.53 cGy in Plan B. All while meeting the target coverage of > 95% isodose line. Statistical testing showed a significant difference between the two planning techniques of lowering the contralateral dose (p < 0.0001), and normality testing supported the validity of the data analysis. In addition to a substantial dose reduction to the contralateral breast, Plan B maintained equal or improved dose constraint to other surrounding critical organs at risk, including the heart, lungs, spinal cord, and thyroid. The Import High protocol demonstrated consistent outcomes across diverse patient anatomies. These findings suggest that by using the Import High mean dose constraint, it is possible to maintain plan quality while reducing dose to the contralateral breast. This approach may help reduce the risk of long-term side effects and improve the patient’s overall outcomes in whole breast radiation treatments.

W-Rag: Weakly Supervised Dense Retrieval In Rag For Open-Domain Question Answering, Jinming Nian, Zhiyuan Peng, Qifan Wang, Yi Fang

Computer Science and Engineering

In knowledge-intensive tasks such as open-domain question answering (OpenQA), large language models (LLMs) often struggle to generate factual answers, relying solely on their internal (parametric) knowledge. To address this limitation, Retrieval-Augmented Generation (RAG) systems enhance LLMs by retrieving relevant information from external sources, thereby positioning the retriever as a pivotal component. Although dense retrieval demonstrates state-of-the-art performance, its training poses challenges due to the scarcity of ground-truth evidence, largely attributed to the high costs of human annotation. In this paper, we propose W-RAG, a method that draws weak training signals from the downstream task (such as OpenQA) of an LLM, …
