Not So Freakish After All: Foreseeability And The Limits Of Statutory Compliance, Logan A. Blaylock Jun 2026

Not So Freakish After All: Foreseeability And The Limits Of Statutory Compliance, Logan A. Blaylock

Missouri Law Review

When substitute school bus driver Tomika Richardson began her route one October afternoon, the only map she had was a scribbled list of intersections—a rough substitute for the detailed, software-generated route plan with turn-by-turn directions that First Student, Inc. (“First Student”) normally provided to its drivers. The handwritten sheet, reproduced below, was the sole document Richardson received to guide her through a complex urban bus run:


The Disability Discrimination Dilemma: Resolving The Circuit Split Regarding Culpability Standards In Education, Brooklyn N. Cross Jun 2026

The Disability Discrimination Dilemma: Resolving The Circuit Split Regarding Culpability Standards In Education, Brooklyn N. Cross

Missouri Law Review

“Our anger was a fury sparked by profound injustices. Wrongs that deserved ire. And with that rage we ripped a hole in the status quo.” In 1949, eighteen-month-old Judith Heumann contracted polio, losing her ability to walk. Heumann’s parents, German Jewish immigrants to New York, were unaware of the consequences using a wheelchair would have on their daughter’s ability to participate in certain activities. When it became time for Heumann to begin kindergarten, the principal refused to allow the family into the school, stating that Heumann was a “fire hazard.” But Heumann’s mother was tenacious, and the principal eventually admitted …

Mythbusting The Moment Of Threat: Barnes V. Felix In The Context Of Unreasonable Police Seizures, Coleson Manade

Missouri Law Review

A traffic stop for unpaid toll violations should not end in death. Yet on April 28, 2016, Officer Roberto Felix shot and killed Ashtian Barnes during a routine traffic stop for a non-arrestable offense. The legal battle that followed exposed a fundamental tension in Fourth Amendment jurisprudence: how should courts balance officers’ safety concerns with citizens’ rights when analyzing excessive force claims?

Clonal hematopoiesis of indeterminant potential (CHIP) is an age-related phenomenon associated with increased risk of hematologic malignancy. Preclinical studies have shown that infection is a driver of CHIP; clinical studies in people living with HIV suggest a relationship between chronic infection and CHIP, but the association between infection frequency and incident CHIP in the general population remains unknown. We leveraged the atherosclerosis risk in communities study to design a closed prospective cohort study. CHIP was determined based on whole-exome sequencing at 2 time points 20 years apart. Included were 3,367 individuals without cancer or CHIP at time 1 and without …

Corneal innervation research has faced long-standing clinical challenges that only recent technological breakthroughs now make tractable. Advances in single-cell analysis, viral vectors, clinical imaging, and artificial intelligence provide integrated approaches for uncovering molecular mechanisms underlying functional outcomes and facilitating clinical applications. The National Eye Institute's U01-funded consortium on ocular surface innervation addresses major knowledge gaps in characterizing corneal-projecting neurons, understanding neuroimmune and epithelial interactions in the cornea, and translating animal model findings to human pathology. The unique properties of the cornea (transparent, avascular, and densely innervated) make it ideal for neurobiology research on peripheral and central sensory processing. Through a …

BACKGROUND:

Identifying genetic variants conferring resilience to Alzheimer’s disease and related dementia (ADRD) may hold promise for developing therapeutics.

OBJECTIVE:

To determine genetic associations with being dementia-free at age 85 (DF85).

METHODS:

We examined genetic associations, using whole genome sequencing data, with DF85 in three Trans-Omics for Precision Medicine cohorts and the Alzheimer’s Disease Sequencing Project Phenotype Harmonization Consortium. We tested common variants individually and aggregation of rare (MAF≤1%) coding and non-coding variants in DF85 participants (n=3,657) against individuals who were not DF85 (n=20,010). We verified associations using a stricter control set who developed dementia before age 85 (n=5,552).

Treatment Of Obsessive-Compulsive Disorder Via Mental Health Technology, Erika S Trent, Nisha Jagannathan, Eric A Storch Jun 2026

Treatment Of Obsessive-Compulsive Disorder Via Mental Health Technology, Erika S Trent, Nisha Jagannathan, Eric A Storch

Faculty, Staff and Students Publications

Obsessive-compulsive disorder (OCD) is a debilitating neuropsychiatric disorder that remains chronic unless intervened with evidence-based intervention. Cognitive behavioral therapy (CBT) with exposure and response prevention is the gold-standard psychological intervention for OCD, but many individuals do not receive this intervention due to barriers to accessing treatment. Mental health technology tools such as telehealth, computerized programs, internet-delivered CBT, and mobile applications have been adopted to expand the accessibility of CBT. An up-to-date summary of the evidence base of technology-mediated formats of CBT for OCD treatment is provided. Clinical benefits offered by such approaches, current limitations, and future research directions are discussed.

Translational equity means ensuring that diagnostics, treatments, care models, and prevention strategies are developed and implemented so they work for populations with the greatest burden and least access to care. In Alzheimer's disease and related dementias (ADRD), where most evidence derives from highly educated, non-Hispanic White participants at large academic centers, translational equity is critical to prevent misclassification, limited access, and widening disparities and to ensure that underrepresented communities shape how new knowledge moves into practice. Hispanic and other populations in the United States are disproportionately affected by ADRD yet remain underrepresented in research, with gaps especially pronounced in high-poverty …

Non-Isolated Dandy-Walker Malformation: Exome Sequencing Efficacy And Phenotypic Expansions, Sarah Araji, Xiaonan Zhao, Jill A Rosenfeld, Seema R Lalani, Daryl A Scott

Faculty, Staff and Students Publications

Dandy-Walker malformation (DWM) is a rare congenital abnormality of the posterior fossa and the cerebellum and has an incidence of 1 in 10 000 to 30 000 births. Although DWM can present in isolation, it is often associated with other central nervous system (CNS) abnormalities or extra-CNS anomalies (DWM+). A molecular cause is not identified in the majority of individuals with DWM+. This is due, in part, to uncertainty regarding optimal testing strategies and an incomplete understanding of the genetic causes of DWM+. In this study, we analyzed clinical exome sequencing (cES) data from 91 individuals with DWM+ to determine …


Owning Geothermal Energy, Gabriel Eckstein Jun 2026

Owning Geothermal Energy, Gabriel Eckstein

Faculty Scholarship

Geothermal energy holds vast potential for decarbonizing the U.S. energy system, yet the sector remains significantly underdeveloped, supplying only 0.4% of the nation's electricity. A principal barrier to growth is the fragmented and ambiguous legal landscape currently governing ownership of geothermal resources: thirty-three states lack any clear statutory or common-law framework identifying who owns subsurface thermal energy. This Article examines the physical characteristics of geothermal energy, recent developments in the U.S. geothermal sector, and the principal doctrinal approaches that might govern ownership of subsurface heat, including the ad coelum doctrine, common-pool and open-access frameworks, the rule of capture, and public …


Pso-Style Social Influence In An Ant Colony Algorithm For Continuous-Domain Optimization, Ashraf M. Abdelbar, Donald C. Wunsch Jun 2026

Pso-Style Social Influence In An Ant Colony Algorithm For Continuous-Domain Optimization, Ashraf M. Abdelbar, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

ACOR is a well-established Ant Colony Optimization (ACO) algorithm for continuous-domain optimization. In this paper, we propose an extension (which we call ACOR∗) in which several fundamental modifications are made to ACOR's solution construction process, including the incorporation of a social influence mechanism borrowed from Particle Swarm Optimization (PSO). Our modifications to the ACOR algorithm are intended to promote search diversity and combat premature convergence. We experimentally evaluate our proposal in the context of training feedforward neural networks for classification using 65 widely used datasets from the University of California Irvine (UCI) repository, as well as the optimization of several …

Multiplexed Fabry-Pérot High-Temperature Sensing Based On Dispersive Microwave-Photonic Frequency-Time Domain Analysis, Ruimin Jie, Chen Zhu, Bohong Zhang, Koustav Dey, Jie Huang

Electrical and Computer Engineering Faculty Research & Creative Works

We propose and experimentally demonstrate a multiplexed high-temperature Fabry-Pérot (FP) fiber sensing system interrogated by dispersive microwave-photonic frequency-time domain analysis (DM-FTDA). In the proposed architecture, incoherent broadband probing light is modulated by radio-frequency (RF) signals and then reflected by a parallel network of hollow-core photonic crystal fiber FP (HCPCF-FP) sensors. A chirped fiber Bragg grating provides strong dispersion to map the composite FP spectral response into a well-defined microwave transfer function. Unlike conventional optical Fourier-domain multiplexing that requires deliberate cavity-length allocation, the proposed approach achieves multiplexing via delay-dominated discrimination. Distinct delay fibers are assigned to each sensor branch, and an …

To keep up with the ever-increasing performance demand from wireless applications, wireless networks necessitate to operate following an efficient use of the available radio spectrum. Since the radio spectrum is a limited resource, the increasing demand for wireless services and applications to support a wide spectrum of users is a challenge in itself and therefore requires advanced techniques to manage and utilize radio resources efficiently. Dynamic spectrum access (DSA) and sharing play a crucial role in improving the utilization of the radio spectrum, as it departs from the traditional approach of static radio spectrum band allocation which usually leads to …


Golden Hour Open Conceptual Architecture For Citizen-Initiated Structured Urgency Signaling, Jaime Gerardo Figoni Him May 2026

Golden Hour Open Conceptual Architecture For Citizen-Initiated Structured Urgency Signaling, Jaime Gerardo Figoni Him

Defensive Publications Series

Abstract Golden Hour proposes a minimalist, open, and low-bandwidth emergency signaling architecture that enables any citizen to transmit structured urgency information during the critical first hour (“Golden Hour”) of a disaster. The system combines a single-tap severity code (Red / Yellow / Green), a brief guided question sequence, and resilient transmission paths (including SMS/USSD fallback) to generate a live, color-coded situational heat map for emergency responders.

By treating emergency response as a problem of controlling informational entropy, Golden Hour enables a near-instantaneous reduction in chaos while fostering voluntary human solidarity. It is designed as a supplement to — not a …

Black Educology Mixtape "Journal"

As Black academics, researchers, and educators, we navigate the twin topographies of the academy and the open territories of possibility. Connecting these realms, we construct “backyard project” spaces—semi-enclosed areas linking academic spaces and liberated spaces. We use our creation of the backyard as a locality wherein we challenge oppressive, antiquated academic systems and anti-Blackness without waiting for reform. For example, our collective project, the Black Educology Mixtape “Journal,” exemplifies this concept.
