Beyond Climate In Placencia, Belize: Navigating Environmental Change In The Anthropocene, Rory E. Mckenna Nov 2024

Beyond Climate In Placencia, Belize: Navigating Environmental Change In The Anthropocene, Rory E. Mckenna

USF Tampa Graduate Theses and Dissertations

Examining opportunities for climate resilience requires an evaluation of lived experiences of environmental change which benefits from transdisciplinary perspectives. This research examines those experiences through the lens of anthropogenic change which allows for a critical focus on local conditions of environmental change specific to Placencia Village, Belize, over time. An anthropology of the anthropocene framing shifts the focus from the results of the global phenomenon responsible for climate change to the implications of local human-caused environmental change on natural systems, human-environment relationships and dynamics, and the future trajectories of these relationships. Through the use of interviews, go-alongs, participatory mapping, transdisciplinary …

A B-Polynomial Approach To Approximate Solutions Of Pdes With Multiple Initial Conditions, Muhammad I. Bhatti, Md. Habibur Rahman Nov 2024

A B-Polynomial Approach To Approximate Solutions Of Pdes With Multiple Initial Conditions, Muhammad I. Bhatti, Md. Habibur Rahman

Physics & Astronomy Faculty Publications

In this article, we present a novel B-Polynomial Approach for approximating solutions to partial differential equations (PDEs), addressing the multiple initial conditions. Our method stands out by utilizing two-dimensional Bernstein polynomials (B-polynomials) in conjunction with their operational matrices to effectively manage the complexity associated with PDEs. This approach not only enhances the accuracy of solutions but also provides a structured framework for tackling various boundary conditions. The PDE is transformed into a system of algebraic equations, which are then solved to approximate the PDE solution. The process is divided into two main steps: First, the PDE is integrated to incorporate …


"The Political Philosophy That Kant Did Not Write": The Potential For Politics And Political Community In Kant's Third Critique, Rizalino Noble Malabed Nov 2024

"The Political Philosophy That Kant Did Not Write": The Potential For Politics And Political Community In Kant's Third Critique, Rizalino Noble Malabed

Budhi: A Journal of Ideas and Culture

In his Critique of Judgement, Immanuel Kant claims that judgement provides (1) a transition from the theoretical to the practical and unifies philosophy and (2) the principles for an alternative politics and founds the ideal political community. Vital to understanding Kant’s second claim is the idea of sensus communis, which arises from his contention that the judgement of taste appears as universal because taste not only presupposes common sense but is also community sense. This article shows that in his discussion, which moves from reflective judgement, to the judging subject, and to the sensus communis, Kant argues for a potential …

“We Are As We Are, And Ye Are As We Find You” (Or, Finrod Elfsplains The Gift Of Ilúvatar): The ‘Athrabeth Finrod Ah Andreth’ As Core Text In Tolkien’S Legendarium, Sara Brown Nov 2024

“We Are As We Are, And Ye Are As We Find You” (Or, Finrod Elfsplains The Gift Of Ilúvatar): The ‘Athrabeth Finrod Ah Andreth’ As Core Text In Tolkien’S Legendarium, Sara Brown

Journal of Tolkien Research

The "Athrabeth Finrod ah Andreth" is a highly problematic text that directly challenges, if not overturns, the eschatology of Tolkien’s legendarium. In combination with the "Tale of Adanel," we are confronted with the possibility that, in the beginning, the Atani were also deathless and that mortality was a punishment, calling into question the nature of the ‘gift of Ilúvatar’.

Network Differentiation And Identification Of Singletons In Gaussian Networks Under The Bayesian Framework, James Olusegun Adefisoye Nov 2024

Network Differentiation And Identification Of Singletons In Gaussian Networks Under The Bayesian Framework, James Olusegun Adefisoye

Electronic Theses and Dissertations Archive

This dissertation explores Bayesian approaches for network analysis in the context of epigenetic modifications, specifically focusing on Deoxyribonucleic acid methylation (DNA-m) at cytosine-phosphate-guanine (CpG) sites. DNA-m is a key epigenetic modification associated with diseases and infections. Recent research suggests that analyzing joint activities across multiple CpG sites could provide more powerful insights, which can be achieved using network-based approaches, such as Gaussian networks. The first project introduces a Bayesian variable selection method for detecting singletons and reconstructing networks that incorporate singleton status. Singletons, or isolated nodes, can lead to false connections and biased interpretations. The proposed method effectively detects singletons, …

Separating A Particle's Mass From Its Momentum, Mordecai Waegell, Jeff Tollaksen, Yakir Aharonov Nov 2024

Separating A Particle's Mass From Its Momentum, Mordecai Waegell, Jeff Tollaksen, Yakir Aharonov

Mathematics, Physics, and Computer Science Faculty Articles and Research

The Quantum Cheshire Cat experiment showed that when weak measurements are performed on pre- and post-selected system, the counterintuitive result has been obtained that a neutron is measured to be in one place without its spin, and its spin is measured to be in another place without the neutron. A generalization of this effect is presented with a massive particle whose mass is measured to be in one place with no momentum, while the momentum is measured to be in another place without the mass. The new result applies to any massive particle, independent of its spin or charge. A …


Unified Worldline Treatment Of Yukawa And Axial Couplings, James Edwards Nov 2024

Unified Worldline Treatment Of Yukawa And Axial Couplings, James Edwards

School of Engineering, Computing and Mathematics

We provide a worldline representation of the one-loop effective action for a Dirac particle coupled to external scalar, pseudoscalar, vector and axialvector fields. Extending previous work by two of the authors on the pure vector-axialvector case to all four couplings, it allows one to treat the real and the imaginary parts of the effective action in a unified manner, at the price of having a non-Hermitian Hamiltonian. Unlike existing worldline representations, our new worldline action contains terms with an odd number of Grassmann fields, leading to ordering problems that in the worldline formalism are usually encountered only in curved space. …

The Average Number Of Goldbach Representations And Zero-Free Regions Of The Riemann Zeta Function, Keith Billington, Maddie Cheng, Jordan Schettler, Ade Irma Suriajaya Nov 2024

The Average Number Of Goldbach Representations And Zero-Free Regions Of The Riemann Zeta Function, Keith Billington, Maddie Cheng, Jordan Schettler, Ade Irma Suriajaya

Faculty Research, Scholarly, and Creative Activity

In this paper, we prove an unconditional form of Fujii's formula for the average number of Goldbach representations and show that the error in this formula is determined by a general zero-free region of the Riemann zeta function, and vice versa. In particular, we describe the error in the unconditional formula in terms of the remainder in the Prime Number Theorem which connects the error to zero-free regions of the Riemann zeta function.


Understanding Mechanisms For Coastal Marsh Sustainability In A Changing Climate, Ashley R. Booth Nov 2024

Understanding Mechanisms For Coastal Marsh Sustainability In A Changing Climate, Ashley R. Booth

LSU Doctoral Dissertations

In the Chenier Plain of Louisiana and Texas, coastal marshes are subject to high rates of relative sea level rise (RSLR), restricted sedimentation, and declining elevation attributed to subsidence and decades of intensive management. These marshes were created via mineral sedimentation but now largely accrete via organic matter accumulation. This organic matter accumulation (OMA) – or the balance between plant productivity and decomposition – is essential for maintaining elevation and thus long-term sustainability. However, management for elevation is complicated by a poor understanding of how abiotic factors like flooding and salinity impact processes driving OMA and elevation. To better understand …
