Quantum Mechanics, Non-Locality, And The Space Discreteness Hypothesis, Wilson A. Zuniga-Galindo

School of Mathematical & Statistical Sciences Faculty Publications

The space discreteness hypothesis asserts that the nature of space at short distances is radically different from that at large distances. Based on the Bronstein inequality, here, we use a totally disconnected topological space X as a model for the physical space at short distances. However, we consider the time as a real variable. In this framework, the Dirac–von Neumann formalism can be used. This discreteness hypothesis implies that given two different points in space, there is no continuous curve (a world line) joining them. Consequently, this hypothesis is not compatible with the theory of relativity. We propose R×(R×X)3 as …

Study Of A Nonlinear Delayed Parabolic Model For Prion Disease Dynamics With The Unfolded Protein Response, Gangadhara Boregowda, Laurent Pujo-Menjouet, Zhaosheng Feng, Michael R. Lindstrom

School of Mathematical & Statistical Sciences Faculty Publications

Prion diseases are neurodegenerative disorders characterized by the dynamic spread of misfolded toxic proteins in the brain. In this process, the normal cellular prion protein (PrPC) produced by neurons misfolds into a toxic form known as scrapie prion protein (PrPSc). These misfolded proteins propagate through the brain by converting healthy prions into their toxic form. This biological mechanism can be modeled by a system of nonlinear parabolic partial differential equations, accompanied by a nonlinear delayed integral boundary condition. Our primary objective is to establish the existence of nonnegative classical solutions to this system. Furthermore, we derive a priori estimates for …

Anedo, Dennis Beesigamukama, Benson Mochoge, Nicholas K. Korir, Solveig Haukeland, Xavier Cheseto, Moses Nyongesa, Patrick Pwaipwai, Sevgan Subramanian, Abdou Tenkouano, Chrysantus M. Tanga

All Peer-Reviewed Publications

The utilization of insect frass fertilizer in crop production systems has recently gained significant global interest, but there has been limited evidence of its residual benefits in rotational cropping systems. The legacy effects of black soldier frass fertilizers (BSFFF), conventional organic fertilizer (SAFI), inorganic fertilizer (NPK), synthetic nematicide, and their combinations on potato cyst nematode (PCN) management under potato-African nightshade rotational farming systems were investigated. Eight treatments were evaluated: BSFFF, SAFI, chitin-fortified BSFFF (BSFFF+5chitin), NPK + nematicide, combination of BSFFF and NPK so that each supplies 50% of the nitrogen required by potato (50BSFFF+50NPK), combination of SAFI and NPK so …

Hein, Michelle Whirl-Carrillo, Andrea Gaedigk, Michael T. Eadon, Rodney F. Minchin, Sotiria Boukouvala, Adalberto Rezende Santos, Roseann S. Donnelly, José A G Agúndez, Kelly E. Caudle

Manuscripts, Articles, Book Chapters and Other Papers

NAT2 encodes arylamine N-acetyltransferase 2, a key enzyme in the phase II metabolism of arylamines and arylhydrazines. NAT2 is highly polymorphic, resulting in variable distributions of rapid and poor metabolizers across global populations. Here, we detail the process undertaken by the Clinical Pharmacogenetics Implementation Consortium (CPIC) NAT2 Pharmacogene Curation Expert Panel (PCEP) to assign clinical function to NAT2 star (*) alleles using CPIC's standard terminology. Given the observed impact of NAT2 genetic variability on drug response, CPIC convened the NAT2-PCEP to standardize clinical allele function assignments. The NAT2-PCEP is comprised of multidisciplinary and international members, including researchers, clinicians, and implementers …

Algorithmic Oversight: Caremark's Fiduciary Framework Applied To Artificial Intelligence, Samar Singh

Political Science and International Relations: Student Scholarship & Creative Works

Artificial intelligence now drives core corporate decision, such as loan approvals and hiring screens, yet corporate boards have largely treated its governance as a management-level policy questions rather than a fiduciary obligation. This paper argues that this framing is mistaken, using Delaware's Caremark doctrine, as refined by Marchand v. Barnhill, In re Boeing, and In re McDonald's. The relevant cases already impose an enforceable duty on boards to actively oversee mission algorithmic systems, and by applying Marchand's mission-critical standard, this paper demonstrates that AI performs core business functions that expose companies to anti-discrimination, consumer protection, and …

Research outputs 2022 to 2026

Understanding internal hydrodynamics of Direct Contact Membrane Distillation (DCMD) is crucial for desalination performance and mitigating temperature polarization. Despite its importance, quantitative experimental characterization of hydrodynamics governing boundary-layer development and transport enhancement within DCMD channels remains limited. This study presents the first spatially resolved Particle Image Velocimetry PIV measurement of velocity fields inside a smooth, actively operating flat-sheet DCMD channel, linking observed hydrodynamic structures to permeate flux. Two-dimensional velocity fields were captured at different streamwise positions for feed flow rates ranging from 0.7 to 4 L·min−1, enabling analysis of flow evolution and turbulence characteristics relevant to mass transfer. The results …

Regulating Religious Coexistence : The Intricacies Of Interfaith Cooperation In Coastal Kenya, Erik Meinema

Ohio University Press Open Access Books

Regulating Religious Coexistence offers a compelling ethnographic analysis of how Muslims, Christians, and practitioners of indigenous African religions negotiate coexistence in Kenya’s coastal region. The book conceptualizes religious diversity as a dynamic field shaped by multiple partly intersecting and partly conflicting models of interaction. These include the political secularism promoted by the Kenyan state and civil society organizations focused on interfaith harmony, forms of competition between religious groups, and pluralistic practices in which individuals draw on multiple traditions to meet spiritual needs.

Through a close examination of civil society initiatives funded by Western donors to foster peacebuilding and to counter …

Nightside Electron Precipitation Patterns As Observed By Elfin And Cirbe Cubesats, Kun Zhang, Anton V. Artemyev, Xinlin Li, Xiao-Jia Zhang, Vassilis Angelopoulos, Yang Mei, Zheng Xiang, Niklas Grimmich

Publications

The rapidly expanding fleet of low-altitude CubeSats equipped with energetic particle detectors brings new opportunities for monitoring the dynamics of the radiation belt and near-Earth plasma sheet. Despite their small sizes, CubeSats can carry state-of-the-art instruments that provide electron flux measurements with finer energy resolution and broader energy coverage, compared to conventional missions such as POES satellites. The recently launched CIRBE CubeSat measures 250–6,000 keV electrons with extremely high energy resolution, however, CIRBE typically only measures locally-trapped electrons and cannot directly measure the precipitating electrons. This work aims to develop a technique for identifying indications of nightside precipitation using the …
