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.

The integration of algorithmic decisionmaking and artificial intelligence (“AI”) into facial recognition technology poses new, unprecedented risks to privacy and individual autonomy rights, particularly in urban settings. The murder of Brian Thompson, CEO of UnitedHealthcare, in New York City on December 4, 2024, provides a timely case study to examine the deployment of facial recognition systems by the New York Police Department and other law enforcement agencies to identify the suspect. New York City deploys some of the most sophisticated surveillance architecture in the nation, put into place following the terrorist attacks of September 11, 2001. This Article explores the …

Iberian Origins Of New Mexico's Community Acequias, Jose A. Rivera Ph.D., Thomas F. Glick Ph.D.

Faculty Publications

When Spanish officials first entered the northern region of New Spain in the late sixteenth century, they realized that irrigation would be a necessary development in the establishment of permanent communities. To sustain the early settlements, they built irrigation systems following the Iberian model, itself an extension of Arabo-Berber traditions from north Africa and the Middle East.

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 …

Faculty Publications

Individuals in Westernized countries spend most of their time indoors. However, exploration of residential building factors that may influence occupants’ mental health is limited in scientific literature. The purpose of this study was to explore investigator's perceived areas of importance in residences to mental health via survey methods. To that end, we administered the Housing, Occupancy, Materials, and Environment (HOME) survey to assess factors that may influence mental health to those working in the United States (US) Air Force (n = 230) or past military members, US Veterans (n = 180). Self-reported mental health surveys were also administered to the …

War, Wounds, And Strategy: Patient Movement Lessons From The World Wars For Great Power Competition, Phillip R. Jenkins

Faculty Publications

This thesis examines the evolution of the U.S. military's patient movement system during World War I and World War II to evaluate how well it may perform under the conditions of future large-scale combat operations. It asks whether the United States can move, treat, and sustain wounded personnel at the scale and pace required to preserve combat power in a prolonged, high-intensity conflict. Using detailed case studies of the Meuse-Argonne Offensive and the Battle of the Bulge, the analysis focuses on how transportation platforms, organizational structure, and standard operating procedures (SOPs) shaped patient movement under conditions of attrition, disruption, and …

The Risk Of Marginal Inclusion In The Fortune 500: A Quasi-Replication Of Lewis & Carlos (2023), W. Chad Carlos, Yasir Dewan, Ben W. Lewis, Brian P. Reschke, S. Isaac St. Clair

Faculty Publications

Conventional wisdom suggests that being included in an exclusive ranking leads to positive external evaluations. However, Lewis and Carlos (2023) found that firms situated near the threshold for inclusion on the 100 Best Corporate Citizen ranking were devalued by investors. To assess the generalizability of this surprising finding, we quasi-replicate and extend this finding by applying the same regression discontinuity design to the Fortune 500 ranking. We find corroborating evidence: firms near the bottom of the Fortune 500 receive lower external evaluations, not only from investors but also from industry peers. Our findings therefore quasi-replicate and extend Lewis and Carlos’ …

Enhancing Photosynthesis Under Salt Stress Via Directed Evolution In Cyanobacteria, Zhenxiong Jiang, Khondokar Nowshin Islam, Malory Wolfe, Michael O'Connell, Dykia Williams, Ashley Florance, David J. Vinyard, Xiaohui Zhang, Maxwell Brenner, Andor J. Kiss, Xianhua Liu, Xin Wang

Faculty Publications

A key aspect of enhancing photosynthesis is improving the kinetics of photochemical quenching recovery following environmental perturbation or stress. Salt stress exacerbates high light stress in cyanobacteria and leads to severe yield losses in crop plants. Genetic traits that confer salt tolerance without compromising photosynthetic performance are essential for improving photosynthesis under these conditions. Here, we applied accelerated evolution in Synechococcus elongatus PCC 7942 by conditionally suppressing its methyl-directed mismatch repair system to obtain beneficial genetic traits for enhanced photosynthesis under salt stress. We screened over 10,000 mutants and isolated 8 strains with increased biomass or sucrose productivity under salt …

Six Paths Of Global China: A Genealogy Of A Contested Geographical Imaginary, Jessica Dicarlo, Meredith J. Deboom

Faculty Publications

‘Global China’ has emerged as a shorthand for China's relationship to the global, but its axiomatic uses disguise considerable complexity. This article troubles self-evident uses and tidy categorizations of Global China by approaching it as an emergent, pluralistic geographical imaginary warranting critical analysis. Employing a genealogical approach that privileges indeterminacy and inconsistency over linearity and singularity, we draw on wide-ranging sources to reveal the contested, contextual, and contradictory uses of Global China in the contemporary moment. Our analysis identifies six ‘paths’ of Global China: Other, Integration, Bridge, Status, Threat, and Alternative. Each path facilitates distinct yet interlinked claims about …

Neo-Gender Balancing In Saudi Arabia: Divorce Under Social Exchange Theory, Abdullah F. Alrebh, Radhi H. Al-Mabuk

The Influence Of Geographic Ranges, Climatic Niches And Temperature Fluctuations On Population Variability, Cleber Ten Canten, Lauren Holian, Tad Dallas

Faculty Publications

The existence of patterns in population dynamics across species geographic ranges and climatic niches is a pervasive idea in ecology. Population variability (i.e. temporal variability in population density) should hypothetically increase near range edges or niche limits because of less suitable environments in these areas, but the occurrence of such patterns remains largely unexplored. Further, fluctuations in temperature could pose demographic constraints on populations and also influence their variability. We used Breeding Bird Survey data to show that the population variability of 97 resident North American birds consistently increases towards their niche limits and in areas with more variable temperatures, …

Snow, Ice And Permafrost Landscapes As ‘Frozen Commons’: Examples From Northern Mongolia, Mariia Kuklina, Vera Kuklina, Nikolay Shiklomanov, Alexander Shiklomanov, Kelsey Nyland, Khadbaatar Sandag, Enkh Amgalan Sandag, Natalia Krasnoshtanova, Dmitrii Kobylkin, Alexander Kholodov, Andrey Petrov

Faculty Publications

Cryosphere has a global role as a biogeophysical phenomenon. It affects the livelihoods of people inhabiting permafrost areas and is affected by human activity within and outside of the cryosphere’s geographical span. ‘Frozen commons’ (FCs) are cryosphere resources and landscapes, defined by snow, ice, and permafrost, that are experienced, used, protected and managed by groups of people together. This paper highlights collaboration between herders and scientists aimed at improving the understanding of FCs in northern Mongolia, a region of rapid cryosphere transformation. The impact of climate change on Indigenous and pastoralist communities in Mongolia is profound, leading to the damage …

Nourishing The Living Tree: Vincent Macdonald And His Constitutional Thought, Preston Jordan Lim

Faculty Publications

Since the enactment of the Canadian Charter of Rights and Freedoms, Canadian judges have increasingly approached the Constitution through a living constitutionalist lens, adapting the Constitution to contemporary realities and treating the text as but one interpretive modality alongside purpose and context. The Supreme Court has rooted this living constitutionalism in the Judicial Committee of the Privy Council’s judgment, Edwards v Attorney General of Canada, wherein Lord Sankey introduced the metaphor of the “living tree.” Justice Robert Sharpe and Professor Patricia McMahon have suggested that the “living tree metaphor remained a forgotten footnote until 1982.” Indeed, more formalist approaches towards …

The Role Of Civic Education On The Types And Causes Of Bullying In School, Besim Gollopeni, Ferdi Kamberi, William R. Henninger

The integration of Silicon Carbide (SiC) nanoparticles into Laser Powder Bed Fusion (LB-PBF) Molybdenum (Mo) printing represents a significant advancement in refractory metal additive manufacturing. Our investigation examined how varying SiC nanoparticle sizes affect the microstructural and electrical properties of LB-PBF-printed molybdenum components while maintaining a 0.01 mass fraction of Mo. At an Linear Energy Densities (LED) of 1.8 J/mm, the addition of 80 nm SiC particles achieved a 46% reduction in porosity, while sheet resistance decreased by 6% at LED of 2.0 J/mm with 80 nm SiC particles. These performance improvements stem from several mechanisms: SiC particles serve as …

The Next Four Years: Geographical Reflections On The Second Trump Administration, Caroline R. Nagel, Peter Hopkins

Faculty Publications

In this introductory essay, we reflect on the significance of the re-election of Donald Trump to the presidency in the United States, and we provide some context for interpreting Trump's second term. Two of Trump's early policy moves—the release of billions of gallons of water from reservoirs in California and the granting of refugee status to Afrikaners—portend four years of politics based on alternative facts, conspiracy theories, and racial grievances. Trump's political agenda has received a significant boost from Silicon Valley billionaires, who are keen to eliminate regulatory bureaucracy. Paradoxically, while allied with high-tech futurists, Trump's policies hearken to an …

Distinct Brain Age Gradients Across The Adult Lifespan Reflect Diverse Neurobiological Hierarchies, Nicholas Riccardi, Alex Teghipco, Sarah Newman-Norlund B.S., M.A., Roger Newman-Norlund Ph.D., Ida Rangus, Chris Rorden, Julius Fridriksson Ph.D., Leonardo Bonilha

Faculty Publications

‘Brain age’ is a biological clock typically used to describe brain health with one number, but its relationship with established gradients of cortical organization remains unclear. We address this gap by leveraging a data-driven, region-specific brain age approach in 335 neurologically intact adults, using a convolutional neural network (volBrain) to estimate regional brain ages directly from structural MRI without a predefined set of morphometric properties. Six distinct gradients of brain aging are replicated in two independent cohorts. Spatial patterns of accelerated brain aging in older adults quantitatively align with the archetypal sensorimotor-to-association axis of cortical organization. Other brain aging gradients …

Stomatal Distribution And Post-Fire Recovery: Intra-And Interspecific Variation In Plants Of The Pyrogenic Florida Scrub, Genevieve Triplett, Aaron S. David

Faculty Publications

Premise

Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss. The Florida scrub—a hot, dry, shrub-dominated habitat—historically has experienced frequent fire, yet decades of anthropogenic suppression coupled with the reintroduction of prescribed burns has led to varied fire regimes. In this study, we investigated the links between amphistomy and fire with regard to the presence of the trait across species in this pyrogenic habitat and within-species variation before and after experimental fire and across a …

Enhanced Nuclear Binding Near The Proton Drip Line Opens Possible Bypass Of The 64Ge Rapid Proton Capture Process Waiting Point, Zachary Meisel, W.-J Ong, J. S. Ranhawa

Faculty Publications

We performed astrophysics model calculations with updated nuclear data to identify a possible bypass of the ⁶⁴Ge waiting point, a defining feature of the rapid proton capture (rp) process that powers type I X-ray bursts on accreting neutron stars. We find that the rp-process flow through the 64Ge bypass could be up to 36% for astrophysically relevant conditions. Our results call for new studies of ⁶⁵Se, including the nuclear mass, β-delayed proton emission branching, and nuclear structure as it pertains to the 64As(p, γ) reaction rate at X-ray burst temperatures.
