Ablation Properties of HfC-SiC-WC Ultra-High Temperature Ceramics Produced by Pressureless Sintering

Description: HfC-SiC is one of the leading thermal insulation ceramics that has the potential to perform well under high thermomechanical loads. In this study, we explore the use of pressureless sintering to produce this material at relatively low temperatures (2100 oC) and focus on understanding the effect of adding WC, in the 0 to 20 wt.% range, on its ablation resistance. The sintered samples were evaluated for their relative density, phase composition, morphology, microstructure, Vickers hardness, … more

An Analysis, Software Implementation, and Applications of Discrete-Time K-Winners-Take-All Neural Network

Description: The K-Winners-Take-All Neural Networks (KWTA NNs) identify the K largest or smallest among N inputs, where 1 ≤ K < N, and both K and N are any finite integers. These networks produce positive outputs corresponding to the K largest inputs, and negative (or zero) outputs for the remaining N − K inputs. KWTA NNs are used in numerous applications such as pattern classification, pattern recognition, parallel sorting, parallel filtering, adversarial defense, dynamic tracking of robot systems, and tel… more

At The Polls: Analyzing Vote Choice in a Presidential Election by American Indians Utilizing Linked Fate

Description: Does linked fate apply to every minority group, or are there groups where linked fate does not hold? Utilizing the largest American Indian survey sample in political science, I test whether “Native Linked Fate” has a significant relationship with vote choice in the 2020 Presidential Election, analyzed by utilizing a multinomial logistic regression. I find that there is no significant relationship between Native Linked Fate and Vote Choice in the analysis; though I do find significant relationsh… more

Automated Methods to Evaluate the Quality of Distractors in College-Level MCQS

Description: Generative artificial intelligence holds significant potential to transform the field of education, particularly by assisting researchers in creating course materials and assessment items. One critical component in the generation of multiple-choice questions (MCQs) is the construction of distractors or incorrect answer options. Effective distractors must maintain a delicate balance between plausibility, i.e., the ability to mislead students who lack full mastery of the subject, and clarity: to … more

Beyond Deception: AI Ethics, Consumer Influence, and Corporate Governance in Authoritarian Contexts

Description: This study advances information systems theory by examining the complex convergence of AI-driven consumer influence, technological deception, and ethical governance in authoritarian contexts. While previous research has explored these challenges independently, their intersection creates unprecedented theoretical and practical complexities that remain inadequately addressed. Drawing on sociotechnical systems theory and institutional logic perspectives, we develop comprehensive frameworks address… more

Compatibility Evaluation of Hydrogen Blends in Current and Next Generation Regulator Alloys

Description: For the past several decades, there has been increasing interest in renewable energy sources that can be easily integrated into our existing energy infrastructure to reduce greenhouse gas emissions. One practical solution to reduce emissions in the current energy economy is to blend hydrogen into the existing natural gas pipeline infrastructure. However, hydrogen embrittlement (HE) is a major concern preventing this from becoming a reality. This work looks at the effects of hydrogen-natural gas… more

Computational Methods for Peptide Identification and Protein Inference in Metaproteomics

Description: Metaproteomics enables the functional profile of complex microbiomes in human, environmental and ecosystem contexts. However, accurate protein identification remains the computational bottleneck. Tandem mass spectra must be searched against vast, sample-specific protein sequences spanning hundreds of taxa; database incompleteness, sequence variation, post-translational modifications, and chimeric spectra degrade sensitivity and calibration. Cross-laboratory comparisons further reveal variabilit… more

Development of a Computational Model to Assess the Thermal Impact of Photothermal Hearing Preservation Methods

Description: More than 30% of adults above 65 suffer from some form of hearing loss un the United States, which is expected to double by the year 2060. Hearing loss is often treated through the use of cochlear implants or hearing aids. Prevention methods such as photobiomodulation (PBM) could reduce the need for these treatments. PBM has been shown to reduce hearing loss in animals but has not been effective in human studies. However, human studies have been performed using shorter wavelengths and lower pow… more
