Symbiotic International Law: Combatting Uyghur Forced Labor, Preston Jordan Lim

Faculty Publications

Since 2017, the Chinese government has launched a campaign of repression against the Muslim Turkic minorities of Xinjiang, a region located in China’s Northwest. While most scholars have focused on the mass internment of Uyghurs and other minorities, this Article highlights an under-discussed aspect of China’s campaign: the construction of a sophisticated forced labor system. Minority forced labor supplies key sectors of the global economy—from the automotive to the energy sectors—and allows Chinese companies to outcompete foreign firms. The unprecedented scope and sophistication of what I term the “modern Xinjiang forced labor system” imperils the very future of the international …

Human Gut Commensal Alistipes Timonensis Modulates The Host Lipidome And Delivers Anti-Inflammatory Outer Membrane Vesicles To Suppress Colitis In An Il10-Deficient Mouse Model, Ethan Older, Mary K. Mitchell, Andrew Campbell, Xiaoying Lian, Michael Madden, Yuzhen Wang, Lauren E. Van De Wal, Thelma Zaw, Brandon N. Vanderveen, Rodney Tatum, E. Angela Murphy, Yan-Hua Chen, Daping Fang, Melissa Ellermann, Jie Li

Faculty Publications

Correlative studies have linked human gut microbes to specific health conditions. Alistipes is one such microbial genus negatively linked to inflammatory bowel disease (IBD). However, the protective role of Alistipes in IBD is understudied, and the underlying molecular mechanisms remain unknown. In this study, colonization of Il10-deficient mice with Alistipes timonensis DSM 27924 delays colitis development. Colonization does not significantly alter the gut microbiome composition, but instead shifts the host plasma lipidome, increasing phosphatidic acids while decreasing triglycerides. Outer membrane vesicles (OMVs) derived from Alistipes are detected in the plasma of colonized mice, carrying potentially immunomodulatory metabolites into the …

Citizen Perceptions On The Use, Management And Availability Of Green Spaces In A Mediterranean Region, Daniel Jato-Spino, Fabio Capra-Ribeiro, Vanessa Moscardo, Laura Gallardo

Water electrolysis technologies for hydrogen production are receiving significant attention due to a drastic reduction in the cost of renewable energy sources in recent years. Though traditional alkaline and proton exchange membrane water electrolyzers are receiving the most commercial attention, the anion exchange membrane water electrolyzer (AEMEL) has the potential to be much lower in cost. AEMELs have recently shown remarkable progress in terms of performance and durability. However, they are still mostly operated with expensive platinum group metal (PGM) catalysts on both the anode and cathode. To achieve low cost, either PGM-free or ultra-low loading PGM catalysts are needed. …

An International Perspective On Geography Curricula: Paving A Way Forward For Geographical Thinking, Tomáš Bendl, Hilde Storrøsæter, Lene Møller Madsen, David Trokšiar, Raphaële De La Martinière, Shanshan Liu, Sizakele Serame, Jerry T. Mitchell, Péter Bagoly-Simó, Yushan Duan, Gillian Kidman

Faculty Publications

Geographical thinking is a cornerstone of modern geography education. Despite its universal value, no large-scale international study has systematically examined its integration into diverse curricular documents. This study investigates how geographical thinking is embedded in the curricula of nine countries, focusing on content and procedural dimensions. Using a structured analytical framework, the research reveals significant patterns and gaps, particularly the underrepresentation of place as a central concept, the lack of explicit focus on geographical thinking, and the limited emphasis on its procedural dimension. The findings emphasise the need for stronger interconnections between these dimensions to promote a more comprehensive approach …

Consequently, data on the prevalence and drivers of intimate partner violence in different parts of sub-Saharan Africa are inadequate. Therefore, this study was designed to investigate the prevalence and predictors of intimate partner violence against men in Kisumu slums, Kenya.

Methods

This retrospective cross-sectional study included 398 randomly selected men in intimate relationships aged 18–54 years and residing in Kisumu slums. The sampling frame used was from Community Health Volunteers covering the area of study. Data collection …

Perceptions Of Spirituality And Of God: A Psychological Qualitative Study, Christopher E. Peck, Timothy B. Smith, Jamila Mastny

Faculty Publications

The majority of people living in the U.S. report that spirituality is an important part of their life that is influential to their well-being. However, individuals vary widely in how they conceptualize spirituality, which often stems from and overlaps with their conceptualizations of God or so-called “God image”. Examination of people’s experiences of spirituality and conceptualization of God can enable psychologists to improve their understanding of individuals’ core personal experiences. This study evaluates both spirituality and God image, as well as the relationship between these two constructs, using qualitative hermeneutic analysis of interviews with 63 adults (51% women, 49% men, …

Shedding Light On Inequities Of Power Outages Through Data Transparency, Kelly A. Stevens, Sanam K. Aksha, Mohammed Siddiqur Rahman, Elizabeth Trader, Herbert Longenecker, Rebecca Entress

Faculty Publications

In a changing climate, the electricity grid is increasingly exposed to more extreme weather that results in significant power outages. Further, lower income and racial-ethnic minority households are more likely to experience a higher frequency and duration of power outages compared to less socially vulnerable groups. The literature on the unequal impacts of power outages is a new, growing area of research that has been stymied in part due to the difficulty acquiring high spatial resolution, historical power outage data from utilities. In this Perspectives article, we review the availability of power outage data, and what can be learned from …

Prescribed Fire Leads A Pine Flatwoods Specialist Tree Frog To Seek Local Refugia, Ian Biazzo, Pedro F. Quintana-Ascencio

Faculty Publications

Pine savannas of the southeastern United States evolved with frequent low-intensity wildfires. Today, land managers use prescribed fires to restore this ecological process while also controlling vegetative fuel accumulation. Given the ubiquitous application of this management tool, studies should consider impacts on target and nontarget taxa in these systems. During fires, animal populations persist in the landscape when individuals emigrate to unburned areas or seek refugia within the burn zone; otherwise, they experience local extirpation. We examined the effect of prescribed fires on a pine flatwoods specialist frog, the pinewoods treefrog Dryophytes femoralis, in a frequently burned pine landscape. …

Perceived Adherence-Related Barriers For Youth Living With Hiv In The Southern United States, Kate Weaver, Sarah J. Miller, Sayward Harrison

Faculty Publications

Objective: Youth are at high risk for HIV, accounting for 19% of new diagnoses in the United States (US) in 2021. Highly effective HIV treatment is available in the form of antiretroviral therapy (ART), which enables individuals with HIV to achieve viral suppression. However, youth living with HIV (YLHIV) have poorer ART adherence and lower rates of viral suppression than adults. This study aimed to explore the perspectives of YLHIV and their HIV care providers on barriers and facilitators to ART adherence for YLHIV in the southern US. Methods: Semi-structured qualitative interviews were conducted with YLHIV (n = 16) …

Development And Demonstration Of The Operational Sustainability Index (Opsi): A Multidimensional Metric For Building Performance Evaluation, Oluwafemi Awolesi, Margaret Reams

Faculty Publications

In promoting sustainable cities and societies, accelerating the shift from sustainable building design to sustainable building operations is essential. A persistent challenge lies in the absence of a unified, multidimensional metric that enables meaningful performance comparisons across buildings of similar types and functions, both regionally and globally. This study develops and demonstrates the operational sustainability index (OPSi)—a novel metric grounded in case study research that integrates indoor environmental quality (IEQ) and energy utility quality (EUQ). OPSi is applied to six buildings in three comparative cases: (1) LEED-certified and non-certified dormitories, (2) LEED-certified and non-certified event buildings, and (3) male- and …

Maximum-Likelihood Estimation Of Glandular Fraction For Mammography And Its Effect On Microcalcification Detection, Bryce J. Smith, Joyoni Dey, Lacey Medlock, David Solis, Krystal Kirby

Faculty Publications

Breast tissue is mainly a mixture of adipose and fibro-glandular tissue. Cancer risk and risk of undetected breast cancer increases with the amount of glandular tissue in the breast. Therefore, radiologists must report the total volume glandular fraction or a BI-RADS classification in screening and diagnostic mammography. In this work, a Maximum Likelihood algorithm accounting for count statistics and scatter is shown to estimate the pixel-wise glandular fraction from mammographic images. The pixel-wise glandular fraction provides information that helps localize dense tissue. The total volume glandular fraction can be calculated from pixel-wise glandular fraction. The algorithm was implemented for images …

Our understanding of the γ-ray sky has improved dramatically in the past decade, however, the unresolved γ-ray background (UGRB) still has a potential wealth of information about the faintest γ-ray sources pervading the Universe. Statistical cross-correlations with tracers of cosmic structure can indirectly identify the populations that most characterize the γ-ray background. In this study, we analyze the angular correlation between the γ-ray background and the matter distribution in the Universe as traced by gravitational lensing, leveraging more than a decade of observations from the Fermi-Large Area Telescope (LAT) and 3 years of data from the Dark Energy Survey (DES). …

We report on IXPE and NuSTAR observations beginning 40 days after the 2024 outburst onset of magnetar 1E 1841−045, marking the first IXPE observation of a magnetar in an enhanced state. Our spectropolarimetric analysis indicates that both a blackbody (BB) plus double power-law (PL) and a double blackbody plus power-law spectral model fit the phase-averaged intensity data well, with a hard PL tail (Γ = 1.19 and 1.35, respectively) dominating above ≈5 keV. For the former model, we find the soft PL (the dominant component at soft energies) exhibits a polarization degree (PD) of ≈30% while the hard PL displays …

Pulsar wind nebulae (PWNe) are among the most efficient particle accelerators in the Universe; however, the physical conditions and magnetic geometry in their inner regions remain poorly understood. X-ray polarization now provides a unique opportunity to investigate the magnetic field structure and turbulence properties close to the sites where high energy particles are accelerated. Here, we report on recent X-ray polarization measurements of the PWN 3C 58 by the International X-ray Polarimeter Explorer (IXPE). 3C 58 is a young system that displays a characteristic jet-torus structure that, unlike those in other PWNe, is observed almost edge-on. This nebula exhibits a …

Anomalous Collective Modes In Atomic Nuclei Within The Proton-Neutron Interacting Boson Model, Wei Teng, Yu Zhang, Sheng Nan Wang, Feng Pan, Chong Qi, J. P. Draayer

Faculty Publications

Novel collective modes characterized by a B4/2 ratio (≡B(E2;41⁺→21⁺)/B(E2;21⁺→01⁺)) less than 1.0 that were observed recently have been identified within the proton-neutron interacting boson model (IBM-2) using the consistent-Q Hamiltonian. These modes are shown to give rise to triaxial spectral features, including significant band mixing. The results provide a compelling explanation for the deeply suppressed B4/2 ratio observed in ¹⁶⁶W, ^168,170Os, and ¹⁷²Pt, offering new insights into the B(E2) anomaly phenomenon in neutron-deficient nuclei.

Theory Of Two-Level Tunneling Systems In Superconductors, Junguang He, Wei Ting Lin, J. A. Sauls

Faculty Publications

We develop a field theory formulation for the interaction of an ensemble of two-level tunneling systems (TLSs) with the electronic states of a superconductor. Predictions for the impact of two-level tunneling systems on superconductivity are presented, including Tc and the spectrum of quasiparticle states for conventional BCS superconductors. We show that nonmagnetic TLS impurities in conventional s-wave superconductors can act as pair-breaking or pair-enhancing defects depending on the level population of the distribution of TLS impurities. We present calculations of the enhancement of superconductivity, both Tc and the order parameter, for TLS defects in thermal equilibrium with the electrons and …

Quantum Classical Algorithm For The Study Of Phase Transitions In The Hubbard Model Via Dynamical Mean-Field Theory, Anshumitra Baul, Herbert Fotso, Hanna Terletska, Ka Ming Tam, Juana Moreno

Faculty Publications

Modeling many-body quantum systems is widely regarded as one of the most promising applications for near-term noisy quantum computers. However, in the near term, system size limitation will remain a severe barrier for applications in materials science or strongly correlated systems. A promising avenue of research is to combine many-body physics with machine learning for the classification of distinct phases. We present a workflow that synergizes quantum computing, many-body theory, and quantum machine learning (QML) for studying strongly correlated systems. In particular, it can capture a putative quantum phase transition of the stereotypical strongly correlated system, the Hubbard model. Following …

Interval Spectrum For Electric Quantum Walk And Related Skew-Shift Cmv Matrices, Fan Yang

Faculty Publications

We show that for a family of quantum walk models with electric fields, the spectrum is the unit circle for any irrational field. The result also holds for the associated CMV matrices defined by skew-shifts, as well as a family of the Blattner and Browne model. Generalizations to CMV matrices with skew-shifts on higher dimensional torus are also obtained.

Unwarranted Warrants?: An Empirical Analysis Of Judicial Review In Search And Seizure, Brett James Hashimoto, Miguel F.P. De Figueiredo, Dane Thorley

Faculty Publications

Every year, police perform searches governed by the Fourth Amendment on hundreds of thousands of individuals and their property throughout the United States. Many of the academy’s most decorated scholars have focused on the genesis and jurisprudential nature of the Fourth Amendment’s warrant requirement. Surprisingly, we know almost nothing about how the Fourth Amendment regulates searches and how searches actually work in practice.

In this Article, we pull back the curtain on the search and seizure process by presenting the largest quantitative study of warrants of any kind. We analyze over 33,000 warrant applications filed through Utah’s “e-Warrants” system over …
