Sarcopenia in alcohol-related liver disease (ALD) is of high clinical significance, but there are no effective treatments. Hyaluronan 35 kDa (HA35), a glycosaminoglycan polymer, modulates responses to Toll-like receptor 4 (TLR4), a lipopolysaccharide receptor, to improve hepatic and macrophage function in ALD. We evaluated skeletal muscle responses to HA35 in preclinical models of ALD. Responses to ethanol, lipopolysaccharide (LPS), and HA35 were studied in differentiated murine C2C12/human-induced pluripotent stem cell (hiPSC)-derived myotubes, and wild-type/HA receptor CD44 knockout (CD44^—/—) mouse models of ALD (mALD). Signaling molecules and measures of protein homeostasis (proteostasis) were quantified by immunoblots, mitochondrial oxidative function …

Efficiency Evaluation Of Different Methods For Nitrogen Removal In Municipal Wastewater Treatment Plants: An Integrative Review, Cristiane G. Ferrarezzi, Juliana Canto Duarte

The School of Sustainability Engineering and Environmental Engineering (SEE) Graduate Student Publications

Domestic wastewaters present high nitrogen levels due to the urea and ammonia, which are excreted into urine. Municipal wastewater treatment plants (WWTP) normally face some challenges in keeping their treated wastewater at a low total nitrogen concentration, since the majority of their wastewater is domestic. Low nitrogen levels in the treated wastewater are important to avoid increasing eutrophication of the receptor body, which receives the treated wastewater. This work presents an integrative review considering studies related to denitrification in domestic WWTPs published from January 1st, 2018, to April 30th, 2023. This review aims to identify the most effective methods for …

Tip Penetration Test For Rapid In-Line Assessment Of Static Yield Stress During 3d Concrete Printing Process, Ali Fasihi, Nicolas A. Libre

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The static yield stress of printable cementitious materials is a critical parameter governing the shape stability and buildability of 3D printed concrete structures. Among various testing techniques, the penetration test has emerged as a promising method for in-situ measurement of static yield stress during printing process. However, the applicability of the penetration test for in-line monitoring of static yield stress remains limited due to the necessity for substantial material thickness. To address this challenge, this study proposes a novel tip penetration test, which enables static yield stress determination without the requirement for full cone submergence, thereby facilitating assessment of thin …

Rheological And Micro Properties Of High-Viscosity Binder-Incorporated Polyphosphoric Acid And Rock Asphalt, Feng Ma, Xinye Jiang, Zhen Fu, Chongxin Zhu, Jenny Liu, Ke Shi, Yalu Wen, Yao Zhang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

To enhance the performance of high-viscosity modified asphalt (HVMA), polyphosphoric acid (PPA) and North American rock asphalt (NA-RA) were incorporated into styrene-butadiene-styrene (SBS)/crumb rubber (CR) composite modified asphalt, resulting in two distinct types of HVMA. The two HVMA types were evaluated at various dosages using a dynamic shear rheometer (DSR), bending beam rheometer (BBR), fluorescence microscope (FM), and Fourier infrared spectroscopy (FT-IR) tests. These tests provided both macroscopic and microscopic insights into their properties. The findings indicated that both PPA and NA-RA modify the asphalt's internal structure, enhancing its temperature resistance. PPA primarily improved high-Temperature performance, while NA-RA enhanced low-Temperature …

A Rapid Field Moisture Measurement Unit For Compaction Acceptance Of Unbound Materials, Chuanjun Liu, Xiong Zhang, Jenny Liu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The moisture content (MC) was a critical parameter that needed to be monitored in geomaterial compaction. Nuclear density gauges (NDGs) had been the practice in MC and density measurement for decades but had become less desirable due to cost, regulatory, and safety concerns. Meanwhile, lightweight deflectometers (LWDs), proposed as an alternative to NDGs, did not have a function of MC measurement. This study aimed to identify a rapid field moisture analyzer to work with LWDs for evaluating the compaction acceptance of unbound materials in situ. The study started with evaluating the effectiveness and practicability of two existing moisture analyzers recommended …

There Is No One-Size-Fits-All Approach To Sovereign Finance, Guan Seng Khoo, Annie Koh

Research Collection Lee Kong Chian School Of Business

In a commentary, SMU Professor Emeritus of Finance (Practice) Annie Koh and Khoo Guan Seng, Asia-Pacific advisory council member of the SWF Academy and EU-Asean Centre, opined that in a volatile world, the strength of a sovereign wealth fund lies in its ability to fulfil its specific, sovereign purpose. Prof Koh and Mr Khoo said that sovereign wealth funds are bespoke instruments of national policy, and in the world of sovereign capital, one size does not, and cannot, fit all. They noted that each fund is a reflection of a country’s unique ambitions, its resource endowments and its specific fears …

Perceptions Of Game-Based Assessments: The Role Of Test Takers' Occupational Background, Marie L. Ohlms, Klaus G. Melchers, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Game-based assessments (GBAs) have become increasingly popular in personnel selection. However, research on perceptions of GBAs has yielded mixed results, highlighting the need to explore variables that may shape perceptions of GBAs. Therefore, we examined whether test takers' occupational background and other person-related characteristics (i.e., gender, age, video game usage, openness to experience) are associated with their perceptions of GBAs. N = 179 individuals from technical and social occupational backgrounds rated their perceptions of GBAs and non-gamified tests. We found that GBAs were generally rated more positively than non-gamified tests in terms of organizational attractiveness, behavioral intentions toward the organization, …

Defending Code Language Models Against Backdoor Attacks With Deceptive Cross-Entropy Loss, Guang Yang, Yu Zhou, Xiangyu Zhang, Xiang Chen, Terry Yue Zhuo, David Lo, Taolue Chen

Research Collection School Of Computing and Information Systems

Code Language Models (CLMs), particularly those leveraging deep learning, have achieved significant success in code intelligence domain. However, the issue of security, particularly backdoor attacks, is often overlooked in this process. The previous research has focused on designing backdoor attacks for CLMs, but effective defenses have not been adequately addressed. In particular, existing defense methods from natural language processing, when directly applied to CLMs, are not effective enough and lack generality, working well in some models and scenarios but failing in others, thus fall short in consistently mitigating backdoor attacks. To bridge this gap, we first confirm the phenomenon of …

Property Law For Positive Externalities: Carving New Sticks For The Bundle, J.B. Ruhl, James Salzman

William & Mary Law Review

Property law has long confronted a troubling puzzle: Why does doctrine focus so much on eliminating harms flowing as negative externalities from uses of property—curbing pollution, nuisances, and other harmful land uses—while largely ignoring the potential to encourage positive externalities? Why such a strong focus on preventing bads instead of promoting goods? Using a case of a natural capital resource and the ecosystem services of flood control, water purification, and pollination it provides, this Article explains how and why existing doctrine fails to recognize these benefits as distinct property interests, leading to systematic underinvestment in conservation and service provision. We …

Digital Ecosystems And Data Regulation, Andrew Rhodes, Jidong Zhou, Junjie Zhou

Cowles Foundation Discussion Papers

This paper develops a framework in which a multiproduct ecosystem competes with multiple single-product firms in both price and innovation. The ecosystem can use data from one product to improve the quality of its other products. We use the framework to study three regulatory policies aimed at leveling the playing field. Restricting the ecosystem’s cross-product data usage, or forcing it to share data with single-product firms, benefits those firms and induces them to innovate more. However, these policies also dampen the ecosystem’s incentive to collect data and innovate, potentially raising prices. Consumers are better off only when single-product firms are …

Digitally Branded: The Developmental Catastrophe Of Juvenile Sex Offender Registries, Tammi Walker

University of Richmond Law Review

Juvenile sex offender registration was never a natural fit for the youth justice system, but in the digital age, it has become deeply harmful. What began as a paper-based precaution has evolved into a sprawling digital regime that permanently brands adolescents at the most formative stage of life. This Article examines how techno- logical change has turned registration into a publicly searchable network of stigma—amplified by data aggregators, search engines, neighborhood apps, and real estate platforms—that makes youthful misbehavior both permanent and inescapable. Drawing on insights from developmental neuroscience and criminology, the Article explains why adolescent sexual misconduct is often …

Integration Of One Health Activities Into Professional Student Education: Successes, Challenges, And Considerations, Karen Gruszynski, Mary Beth Babos, Reagan Bishop, Debra Sullivan, Laroy Brandt

All Faculty and Staff Scholarship

Interprofessional Education (IPE) creates opportunities for multiple disciplines to learn from each other and develop soft skills to improve patient care. One Health similarly emphasizes collaborative and interdisciplinary practice while recognizing the interconnectedness between human, animal, and environmental health. Despite the intersection of IPE and One Health, the meaningful integration of One Health within IPE remains uneven and difficult to operationalize. This perspective synthesizes experiences from multi-college programs implementing One Health-oriented IPE, highlighting successes, challenges, and structural requirements. We argue that for One Health to be successfully integrated into IPE for professional students, it requires extensive logistical planning, coordinated institutional …

Secondary School Students' Engagement In Learning Activities: Validation Of A Short Scale, Feliciano Henriques Veiga, Zi Yang Wong, Johnmarshall Reeve, Shane Jimerson, Antonio Leite, Joan Perales, Sonia Valente, Isabel Martinez

Research Collection School of Social Sciences

Student engagement is a multidimensional construct strongly associated with learning outcomes and academic success. However, its measurement remains challenging, as existing instruments often conflate engagement in learning activities with engagement in the school community. In addition, brief measures are scarce despite their increasing value, and most available instruments do not incorporate agentic engagement. Assessing student engagement in learning activities is, therefore, crucial for monitoring academic progress, identifying students at risk of dropping out, and predicting academic success. This study aimed to validate the 12-item Secondary School Student Engagement in Learning Activities: Short Scale, adapted from a higher education measure, which …

Reconceiving Safety Regulation For Ai And Ml Medical Software, Barbara J. Evans, Eric S. Rosenthal, Azra Bihorac

Vanderbilt Journal of Entertainment & Technology Law

This article explores the challenges of regulating AI and ML clinical decision support tools intended to assist trained health care professionals in delivering clinical care. Two old, twentieth-century regulatory models have dominated discussions of medical AI policy since 2013. Thinking inside these old regulatory boxes has not produced effective regulatory solutions to address the novel risks AI poses in clinical care. The first regulatory box treats software as a medical device, which tasks medical device regulators with making software safe but neglects the crucial roles physicians, nurses, administrators, medical practice regulators, and other health oversight bodies must also play to …

Engineering Enac Constructs To Examine Pip2 And Ubiquitin Competition On Enac Regulation And Stability, Lacie Johnson

Chemistry & Biochemistry Undergraduate Honors Theses

The epithelial sodium channel (ENaC) plays a critical role in sodium homeostasis, fluid balance, and blood pressure regulation. ENaC activity is tightly controlled by post-translational mechanisms, including ubiquitination-mediated degradation and phosphatidylinositol 4,5-bisphosphate (PIP2) dependent channel activation. PIP2 is a phospholipid necessary to facilitate the maximal channel opening. Previous studies suggest that intracellular PIP2 binding sites are located in proximity to ubiquitination sites on ENaC subunits, raising the possibility of PIP2 binding to influence channel stability and function. This thesis aimed to engineer and validate molecular tools capable of examining the interplay between PIP2 binding and ubiquitination in ENaC regulation. A …

Animal and Food Sciences Faculty Publications

An emerging paradigm in public health focuses on enhancing nutrition in existing food staples to reduce chronic disease at the population scale, rather than relying on individuals to change their behavior. This paradigm leverages plant and animal breeding, production practices, and processing to enhance nutrition, whereby foods consumed by millions can be improved at low incremental cost. This article supports and operationalizes this paradigm, illustrating the potential to improve diets through a case study that increases the arabinoxylan fiber content of commodity wheat through classical plant breeding (a non-GMO technology). The approach described in this article proposes to link agricultural …
