A Method For Fine-Scale Identification Of Collapse Columns Based On Offset Vector Tile Domain Seismic Data, Zhang Guangzhong, Liu Song, Shan Rui, Cai Wenrui

Coal Geology & Exploration

Objectives and Methods The YQ mining area in the Qinshui Basin is characterized by complex seismic and geological conditions, as well as well-developed collapse columns and flexure structures. Consequently, conventional three-dimensional (3D) seismic exploration fails to meet the precision requirements for safe coal mining. By constructing a physical model based on the actual geological conditions of the study area, this study conducted forward modeling for the seismic responses of collapse columns under varying azimuths. Accordingly, the azimuthal anisotropy of the collapse columns were systematically analyzed. By employing a regular noise suppression technique based on curvelet transform, combined with prestack migration …

Algebraic Invariants Of Multi-Virtual Links, Louis H. Kauffman, Sujoy Mukherjee, Petr Vojtěchovský Mar 2026

Algebraic Invariants Of Multi-Virtual Links, Louis H. Kauffman, Sujoy Mukherjee, Petr Vojtěchovský

Mathematics: Faculty Scholarship

Multi-virtual knot theory was introduced in 2024 by the first author. In this paper, we initiate the study of algebraic invariants of multi-virtual links. After determining a generating set of (oriented) multi-virtual Reidemeister moves, we discuss the equivalence of multi-virtual link diagrams, particularly those that have the same virtual projections. We introduce operator quandles (that is, quandles with a list of pairwise commuting automorphisms) and construct an infinite family of connected operator quandles in which at least one third of right translations are distinct and pairwise commute. Using our set of generating moves, we establish the operator quandle coloring invariant …

K2p Channels As Key Regulators Of Cardiovascular And Pulmonary Vascular Function, Bradley K Mcconnell Mar 2026

K2p Channels As Key Regulators Of Cardiovascular And Pulmonary Vascular Function, Bradley K Mcconnell

Faculty, Staff and Students Publications

Two-pore domain potassium (K2P) channels are the most recently identified family of potassium channels. They are regarded as the largest group of background “leak” channels, encoded by 15 mammalian KCNK genes, and divided into six subfamilies (TWIK, TREK, TASK, TALK, THIK, and TRESK). These channels have a role in stabilizing the resting membrane potential. Their widespread presence in the heart and vasculature supports cellular homeostasis by regulating cardiac rhythm, vascular tone, and protection against ischemic stress. The TASK, TWIK, and TREK subfamilies are the most abundantly expressed K2P channel subfamilies in the cardiovascular system, and dysregulation of specific members has …

Neurodegenerative diseases feature diverse pathological protein aggregates, including Lewy bodies in Alzheimer's disease (AD) and skein-like filaments in amyotrophic lateral sclerosis (ALS). The physical mechanisms underlying this morphological diversity remain unclear. Here, we demonstrate that aggregation of the prion-like domain of hnRNPA1 (A1PrD), implicated in AD and ALS, is driven by solution composition and phase transition dynamics. Utilizing 3D timelapse and fluorescence lifetime imaging microscopy, we show that solution conditions modulate phase separation, gelation, and fibrillation, resulting in distinct structures such as fibril, gel, and starburst morphologies. Homotypic and heterotypic interactions between A1PrD and RNA were observed to shift the …

Comparative Analysis Of Clearing Methods For 3d Imaging Of The Vasculature In Mineralized Mouse Tissues, Re-Join Consortium, Chih-Wei Hsu, Brendan Lee, Nele Haelterman, Joshua D Wythe

Faculty, Staff and Students Publications

Historically, visualization of vascular networks within the musculoskeletal system, particularly in mineralized tissues such as bones and joints, has been limited to conventional 2D histological approaches. Recent advances in optical tissue clearing technologies and fluorescence imaging approaches in whole, intact tissues offer an entrée to interrogate the vasculature at unprecedented resolution during both musculoskeletal development and in pathologic contexts in three dimensions. However, these clearing techniques were originally not developed for imaging hard mineralized tissues, such as the femur and tibia. Herein, we have optimized tissue decalcification conditions and compared aqueous- and solvent-based tissue clearing approaches to establish an optimal …

Critical Discourse Analysis Of Turnaround Leadership Competencies Using A Transformative Leadership Framework, Kevin D. Mcdonald Mar 2026

Critical Discourse Analysis Of Turnaround Leadership Competencies Using A Transformative Leadership Framework, Kevin D. Mcdonald

USF Tampa Graduate Theses and Dissertations

School turnaround leadership has become a leading strategy to address school underperformance emphasizing rapid and dramatic improvement in a school within the bottom five percent of schools as measured by gains in both mathematics and English Language Arts. However, prevailing turnaround leadership discourse largely centers technical and managerial competencies, often marginalizing leadership practices oriented toward equity, advocacy, and social transformation. This narrowing of leadership is particularly consequential for Black male principals, who are disproportionately assigned to low-performing and turnaround schools and whose leadership practice frequently reflects core elements of transformative leadership.

The purpose of this dissertation was to explore current …
