School of Medicine Publications

Myeloid/lymphoid neoplasms with eosinophilia and tyrosine kinase fusions (M/LN-eo-TK) are uncommon but highly treatable disorders. Among them, FIP1L1::PDGFRA–driven disease is distinguished by marked eosinophilia and multisystem involvement that can rapidly reverse with targeted therapy. We describe a 50-year-old man with uncontrolled diabetes who presented with progressive dyspnea, abdominal discomfort, and painful necrotic scrotal ulcers. Laboratory testing revealed leukocytosis with a striking absolute eosinophil count of 22.1 × 10³/µL, while imaging showed pulmonary infiltrates, small-bowel inflammation, and splenomegaly. Bone marrow examination demonstrated hypercellularity with prominent eosinophilic proliferation. Fluorescence in situ hybridization confirmed a PDGFRA rearrangement with CHIC2 deletion, establishing the diagnosis …

Digital innovations hold immense potential to transform health care delivery, particularly in sub-Saharan Africa, where financial, geographical, and infrastructural constraints continue to hinder progress toward universal health care delivery. Although a growing health tech sector offers creative solutions, few digital health interventions reach scaled implementation. In this paper, we present the digital fit/viability model-an adapted determinant framework to describe facilitators and barriers to moving from digital tools to integrated digital health implementation. We then use this model to describe the specific challenges and recommended solutions when developing digital health tools for health systems in sub-Saharan Africa.

Trusting Jesus To The End: How A Christocentric, Inductive, And Canonical Hermeneutic Best Answers Rapture Debates And Reaffirms Perseverance, James G. Davidian

Doctoral Dissertations and Projects

This dissertation compares the four premillennial end-time theories (i.e., the pretribulation, midtribulation, prewrath, and posttribulation views) to answer whether the Bible literally/explicitly describes two future descents of Christ, multiple future resurrections of saints, a pre-wrath timing, a reascent back to heaven, two last trumpets, two peoples of God, and two standards of protection (as proposed by rapture views) or whether the Scriptures describe only a single future coming of Christ for all saints “after the tribulation” (as held by the posttribulation view). By trusting what Jesus taught and relying on what is explicitly written and repeated in the Bible as …

Medulloblastoma Stem Cell Programs: Molecular Roadmaps Of Disease Progression, Jamie Zagozewski, Parthiv Haldipur, Kathleen J Millen, Tamra E Werbowetski-Ogilvie

Faculty, Staff and Students Publications

Over the last decade, an unprecedented number of sequencing studies have characterized the molecular landscape of pediatric brain cancers, including the highly heterogeneous tumor medulloblastoma (MB). Extensive MB profiling has enabled a much deeper understanding of the primitive neurodevelopmental programs that are hijacked during tumor progression. However, we have yet to successfully target and fully eradicate the putative stem and early progenitor cells that drive MB tumorigenesis. This goal will require better human models that faithfully recapitulate oncogenic events, a deeper understanding of the mechanisms governing cell fate decisions in the primary and metastatic compartments, and comprehensive validation studies of …

Representation Of Inverse Ordered Semigroups By Means Of Symmetric Inverse Semigroups On A Set, Michael Tsingelis

Turkish Journal of Mathematics

A partial one-to-one mapping on a set X is a mapping whose domain is a subset of X. The set of partial one-one mappings on a set X is an inverse semigroup (the symmetric inverse semigroup on X). An element x of an ordered semigroup (S, ·, ≤) is called an inverse element of α ∈ S if α ≤ xαx and x ≤ xαx. An inverse ordered semigroup is an ordered semigroup S for which every element of S possesses an inverse element and the inverse elements of any element of S are in …

Cospectrality Results For Signed Graphs With Two Eigenvalues Unequal To ±1, Willem H. Haemers, Hati̇ce Topcu

Turkish Journal of Mathematics

Recently the collection G of all signed graphs for which the adjacency matrix has all but at most two eigenvalues equal to ±1 has been determined. Here we investigate G for cospectral pairs, and for signed graphs determined by their spectrum (up to switching). If the order is at most 20, the outcome is presented in a clear table. If the spectrum is symmetric we find all signed graphs in G determined by their spectrum, and we obtain all signed graphs cospectral with the bipartite double of the complete graph. In addition we determine all signed graphs cospectral with the …

Beyond Icwa: Within Family Court Systems, Mixed Indigenous Families Confront Ongoing Jurisdictional Violence, Nis Wilbur

American Indian Law Journal

Mixed Indigenous families (MIFs) navigating parental custody in the United States can find themselves trapped in a Battleship®-style jurisdictional maze, where tribal, state, and federal authorities collide unpredictably. This legal mess threatens to separate children from their tribal communities, undermines tribal sovereignty, and can force families into years of costly litigation. The problem is rooted in centuries of white supremacist law and policy that systematically dispossess tribes of culture and self-governance: from the Marshall Trilogy to the boarding school era and harmful adoption schemes. Today, legal frameworks like the UCCJEA remain insufficient as they minimize or ignore tribal civil jurisdiction, …
