Toward Simulating 2d Cell Surfaces In A Disk, Myriam Allred

Mathematics & Statistics ETDs

Certain evolution models of cell surfaces (treated in two-dimensions) involve the solution of the Helmholtz equation with jump conditions enforced on an immersed closed curve. This thesis presents a sparse, modal spectral method for solving such Helmholtz problems. The solution is required to be continuous across the curve, but with a jump discontinuity in the normal derivative proportional to the planar curvature. The method relies on classical Fourier-Chebyshev basis functions, with the application of modal Chebyshev integration matrices to achieve sparse, banded approximations of the Helmholtz equation. The method achieves spectral convergence, despite the inherent low regularity of the relevant …

Derivation Of Adjoint Based Error Estimates For Nonlinear Ordinary Differential Equations With Application To Multistage Sir Models With Demographics, Daniel Alcala

Mathematics & Statistics ETDs

Ordinary Differential Equations (ODEs) are central to the mathematical modeling of various real-world phenomena, from mechanical systems governed by Newton’s laws to epidemic dynamics described by SIR-type ODEs. Since many ODEs do not admit closed-form analytic solutions, we approximate them numerically (e.g., with Euler’s, Runge–Kutta, or other such methods). This raises the key question: How accurate are these numerical solutions? In particular, reliably estimating the error in some quantity of interest (QoI) at time T without having an exact solution is of great scientific interest.

The first main contribution of this thesis is the development and analysis of adjoint-based error …

From Backstage To Front Stage : Understanding Dramaturgical Work Behavior In The Workplace, Yufei Cheng

Lingnan Theses (MPhil & PhD)

Modern organizations often reward “looking busy” rather than genuinely contributing, prompting employees to engage in superficial displays of productivity. This type of behavior can be considered as a previously unexplored yet important form of impression management. While impression management research has predominantly examined outcome-oriented tactics, it has not fully captured the subtler, non-contributory forms of performative behavior that permeate everyday work life. To address this gap, this dissertation introduces Dramaturgical Work Behavior (DWB), a concept grounded in Goffman’ s dramaturgical theory, which outlines how employees enact symbolic “front-stage” performances—such as feigned urgency or exaggerated busyness—to signal conformity without adding real …

But Who Is It For? Introducing A Framework For Critical Reflection On Design And Delivery Of Ethical Participatory Research, Hannah Gardiner, Clare Pettinger, Louise Hunt, Mary Hickson

School of Health Professions

Delivering ethical collaborative research is challenging, requiring disruption of assumptions, academic norms, and ways of working–including long-standing power dynamics. This article proposes a framework to support critical reflection on participatory practice; an adaptation of the wheel of consent. The adapted ‘ILBR’ framework explores the balance of who Initiates (makes requests/offers), does Labour (the action), gets Benefits, and takes on Risks (ILBR) in the conduct of research. This aims to support reflexive design and delivery of ethical participation, including a shift towards consent becoming an ongoing multi-way negotiation of agreements. Particularly it aims to support ‘interpersonal reflexivity’, and navigation of the …

Lessons In Longevity From Blood Stem Cells Under Protein Stress, André Catic

Center on Aging Staff Publications

Blood stem cells are among the body's longest-living cells despite being highly vulnerable to proteotoxic damage, which accelerates their aging. To maintain protein homeostasis (proteostasis), hematopoietic stem cells (HSCs) employ mechanisms such as reduced translation rates, high chaperone activity, autophagy, and selective protein degradation. These strategies mitigate protein misfolding, maintain quiescence, and preserve regenerative potential. Disruptions in proteostasis can lead to the elimination of impaired HSCs through differentiation or apoptosis, ensuring the integrity of the stem cell pool. Due to the systemic impact of the blood on aging and its experimental and clinical accessibility, investigating HSC proteostasis provides insights into …

Structural Variants: Mechanisms, Mapping, And Interpretation In Human Genetics, Shruti Pande, Moez Dawood, Christopher M Grochowski

Faculty, Staff and Students Publications

Structural variations (SVs) represent genomic variations that involve breakage and rejoining of DNA segments. SVs can alter normal gene dosage, lead to rearrangements of genes and regulatory elements within a topologically associated domain, and potentially contribute to physical traits, genomic disorders, or complex traits. Recent advances in sequencing technologies and bioinformatics have greatly improved SV detection and interpretation at unprecedented resolution and scale. Despite these advances, the functional impact of SVs, the underlying SV mechanism(s) contributing to complex traits, and the technical challenges associated with SV detection and annotation remain active areas of research. This review aims to provide an …

P250307e_Uss0068_Twip Defpub Saws As Acf, Matched Filter, And Phase Detection, Christian A. Mohr, Mark Rode, Marco Dannemann

Defensive Publications Series

This invention presents a method and device for real-time analog signal processing using Surface Acoustic Wave (SAW) technology. The system performs three core functions without digital conversion: (1) Autocorrelation Function (ACF) for time-frequency transformation, (2) Matched Filtering for pattern recognition, and (3) Phase Detection of modulated signals.

A SAW chip with interdigital transducers (IDTs) on a piezoelectric substrate decomposes input signals into parallel frequency channels ("frequency bins"). Envelope detection of each channel’s output generates an analog spectrogram. Weighting these outputs with predefined coded patterns (via analog operational circuits) enables instantaneous cross-correlation, acting as a matched filter. For phase-sensitive detection, in-phase/quadrature …
