System For Generating Themed Content Using A Generator-Evaluator Framework, Roy Katz

Defensive Publications Series

Manual creation of themed navigational content for user engagement campaigns can be a slow, resource-intensive, and unscalable process, while general-purpose generative models may lack domain-specific safety guidelines and struggle with thematic consistency. A disclosed system can address these challenges through a dual-model, generator-evaluator framework. A primary generative model can create multiple thematic text candidates for a given instruction. A separate, secondary evaluator model may then assess these candidates using a hybrid evaluation process that combines model-based semantic analysis for attributes, such as safety and logical contradiction, with function-based checks for criteria like length and semantic similarity. The system can iteratively …

Ai-Powered Framework For Test Redundancy Detection And Optimization In Software Projects, Hp Inc

Defensive Publications Series

This disclosure presents an AI-powered solution that leverages Large Language Models (LLMs) and machine learning techniques to identify, analyze, and consolidate redundant test cases. In enterprise projects that are maintained for long period of time, test repositories accumulate significant duplication and redundancy, due to requirement changes in the project, which create significant operational challenges.

Emergent Methodologies: Quantum Qualitative Research, Nicole Weinberg, Gabriel Huddleston, Garrison Daly, Molly Weinburgh

The Qualitative Report

This methodology paper considers the prospects for quantizing qualitative inquiry in the context of equity and program evaluation. This paper first examines how quantum logics have been applied to the social sciences. Quantum logics refers to a set of generalizations, or rules, that embrace uncertainty and relationality, challenging the linear causality of traditional social science. Then, it reflects upon the impact of the COVID-19 pandemic in the local community as a site to reframe findings and methods through the lens of quantum logic. For example, schools may be understood as quantum systems, co-constituted and rhizomatic communities shaped by entanglement and …

Faculty, Staff and Student Publications

Radionuclide-stimulated dynamic therapy (RaST) utilizes Cerenkov-radiating radiopharmaceuticals to activate light-sensitive drugs and materials, generating reactive oxygen species (ROS) that inhibit cancer progression. However, the underlying cell death mechanisms are not fully understood. Using ROS-regenerative nanophotosensitizers coated with a tumor-targeting transferrin-titanocene complex and radiolabeled 2-fluorodeoxyglucose, we found that RaST induced apoptosis and necroptosis, characterized by the activation of RIPK-1, RIPK-3, nuclear factor kappa B, and mixed lineage kinase domain-like pseudokinase, leading to membrane permeabilization, cytokine release, and the expression of immunogenic damage-associated molecular patterns. In immune-deficient breast tumor-bearing mice with adequate stroma and growth factors, RaST did not prevent tumor growth …

Bempedoic Acid: A Novel Lipid-Lowering Pharmacological Agent For The Management Of Dyslipidemia, Hajir Karim Abdul-Husseein

Maaen Journal for Medical Sciences

Bempedoic acid is a newly discovered a novel lipid-lowering non-statin agent used for the management of dyslipidemiaand the reduction of cardiovascular risk. Its therapeutic mechanism of action is mediated by the inactivation of upstream enzymatic activity of adenosine triphosphate-citrate lyase (ATP -citrate lyase) that implicated in the cholesterol biosynthetic pathway. Clinical studies have reported that the treatment with bempedoic acid alone may reduce LDL-C levels via nearly 20% when compared with placebo, and by up to 38% when administered in combination with ezetimibe. This new drug has showed a satisfactory safety and tolerability profile demonstrated by a minimal level of …

The current study examines whether state immigration enforcement policies, such as sanctuary policies that limit local police cooperation with federal immigration enforcement, are associated with female homicide rates in the United States (2016–2021). We examine crude female homicide rates from the National Violent Death Reporting System (N = 244 state-years), which we stratify by race and ethnicity (Hispanic of all races, non-Hispanic Black, and non-Hispanic White) and victim–suspect relationship (domestic vs. stranger homicide). State-years with policies that are more protective of immigrants were not associated with higher homicide rates for any group. Instead, state-years with these policies reported significantly lower …

Pdr-Stgcn: An Enhanced Stgcn With Multi-Scale Periodic Fusion And A Dynamic Relational Graph For Traffic Forecasting, Jie Hu, Bingbing Tang, Langsha Zhu, Yiting Li, Jianjun Hu, Guanci Yang

Faculty Publications

Accurate traffic flow prediction is a core component of intelligent transportation systems, supporting proactive traffic management, resource optimization, and sustainable urban mobility. However, urban traffic networks exhibit heterogeneous multi-scale periodic patterns and time-varying spatial interactions among road segments, which are not sufficiently captured by many existing spatio-temporal forecasting models. To address this limitation, this paper proposes PDR-STGCN (Periodicity-Aware Dynamic Relational Spatio-Temporal Graph Convolutional Network), an enhanced STGCN framework that jointly models multi-scale periodicity and dynamically evolving spatial dependencies for traffic flow prediction. Specifically, a periodicity-aware embedding module is designed to capture heterogeneous temporal cycles (e.g., daily and weekly patterns) and …
