A Taxonomy of AI Governance Approaches: Distinguishing Visibility, Alignment, and Authorization

The term “AI governance” has become semantically overloaded, applied indiscriminately to logging, guardrails, model alignment, dashboards, and policy workflows. This paper introduces a formal taxonomy that distinguishes three fundamentally different governance problems: visibilit...

Westwood Multimodal Transportation Plan

Westwood is experiencing an industrial regeneration that will change the way the area is utilized by the surrounding communities. To be proactive, Henrico County is planning for the future by creating an overlay zoning district and striving for a multimodal environment to ensure...

The Association of Umbilical Cord Blood Neurofilament Light With Nonreassuring Fetal Status: A Prospective Observational Study

( Int J Gynaecol Obstet . 2026 Mar;172(3):1491–1500. doi:10.1002/ijgo.70421) A prospective observational study explored whether neurofilament light (NfL), a marker of neuronal injury, can be reliably measured in umbilical cord blood and whether it is associated with nonreassuring...

Heat and Wave Kernel Expansions for Stationary Spacetimes

Abstract The generator of time-translations on the solution space of the wave equation on stationary spacetimes specialises to the square root of the Laplacian on Riemannian manifolds when the spacetime is ultrastatic. Its spectral analysis therefore constitutes a generalization...

Revisiting localization for BPS black hole entropy

A bstract Macroscopic computation of the degeneracy / index of a BPS black hole requires carrying out string theory path integral over the near horizon geometry of the black hole. It has been suggested that the path integral can be localized to a finite dimensional subspace using...

Increasing Doctoral Student Completion Rates Within the College of Humanities and Sciences at Virginia Commonwealth University

Research on doctoral education primarily focuses on broad fields of study and general attrition. Often overlooked, is an examination of the student at each stage of their program and the challenges they face that can potentially lead to stopping out. This capstone project explore...

Centering Social Equity in the Climate Action Planning Process: Lessons for Richmond, Virginia

The client of this plan is the City of Richmond's Office of Sustainability. The purpose is to assist RVAgreen 2050's in its equity-centered climate action planning and to reach the City of Richmond's frontline communities (those impacted first and worst to climate impacts of inte...

A Framework for Forming Resident-Controlled Manufactured Housing Communities in Richmond

Despite manufactured housing representing one of the most affordable, unsubsidized housing options for families in the United States, the nature of ownership in many manufactured housing communities places families at constant risk of displacement. In mobile home parks, where a h...

Residential Fire Impacts on Richmond, Virginia: A plan for identifying and educating our most vulnerable communities

In 2017, 1.3 million fires in the U.S. caused 3,400 deaths, 14,600 injuries, and $23 billion in loss. Vulnerable populations are less resilient due to their lack of adequate access to financial, medical, and community resources as well as their propensity to reside in substandard...

Old and Unreported Collections of Alpheid Shrimp from the Zoologisches Museum, Berlin, Principally from Melanesia

The dataset comes from a report on which previously unstudied collections of 70 species of alpheid shrimp held by the Zoologisches Museum (at the time of publication, East Berlin) are reported upon. Except for four species from the west coast of the Americas, all specimens were f...

Enriched experience increases reciprocal synaptic connectivity and coding sparsity in higher-order cortex

The integration of new information during sleep reshapes cortical representations that support categorical knowledge. Auto-associative attractor network theories predict that reciprocal excitatory connections help form stable categorical attractors, but direct evidence is missing...

Quantum Pseudorandom Scramblers

Abstract. Quantum pseudorandom state generators ( PRSG s) have stimulated exciting developments in recent years. A PRSG , on a fixed initial (e.g., all-zero) state, produces an output state that is computationally indistinguishable from a Haar random state. However, pseudorandomn...

Calabi–Yau varieties of large index

Call a projective variety X Calabi-Yau if its canonical divisor is Q-linearly equivalent to zero.The smallest positive integer m with mK X linearly equivalent to zero is called the index of X.We construct Calabi-Yau varieties with the largest known index in high dimensions.In our...

Dissecting Anomalies in Conditional Asset Pricing

This paper introduces a novel methodology for analyzing anomalies in conditional asset pricing models with time-varying risk exposures and premia. Our approach extends the conventional two-pass methodology to include both ordinary and weighted least-squares estimation in a condit...

Enhancing Pragmatic Communication in Healthy Aging: A Preliminary Investigation of the Long-Term Effects of the Advanced Cognitive Pragmatic Treatment

Abstract The aging process is associated with changes in cognitive and communicative skills, including pragmatic one, the ability to appropriately use language and other expressive means in social contexts. Despite its importance for quality of life and autonomy, the decline of p...

Responsiveness of epigenetic aging biomarkers to longevity interventions in humans

Abstract Aging biomarkers can potentially allow researchers to rapidly monitor the impact of an aging intervention without the need for decade-spanning trials. However, before the use of aging biomarkers, such as epigenetic clocks, as surrogate endpoints, their responsiveness to...

Developing a model for effective public oversight of intelligence-driven surveillance through an African-focused lens

This article distils the main findings of the Special Issue on public oversight of intelligence-driven digital surveillance in Africa. We explore how the public can perform such oversight better, learning the lessons from moments when public oversight has been attempted and propo...
