Grotesque Evolutions
This original collection of poems explores personal transformation, specifically through three overarching themes: the dream and its significance to waking life and the psyche, the hybridization of the human body with animals or the dismemberment of the body, and the discovery of self through human …

Quadratic differentials and Loewner evolutions
Oded Schramm's discovery of stochastic Loewner evolution (SLE) in 1999 as the scaling limit of many important 2-dimensional random processes on lattices has opened up an exciting area of research. One of the central ideas in his theory is the use of a classic tool in function theory, the Loewner …

Generalised Loewner Evolutions and their driving measures
… interior or at a boundary point. Radial Loewner Evolutions are usually defined on the unit disc D = {z in C: |z| < 1} and normalised in the origin. Alternatively, chordal Loewner Evolutions are normally defined on the upper halfplane H := {z in C: Im(z) > 0} and are normalised at infinity. The …

Asymptotic behavior of some stochastic evolutions in continuum
Diese Dissertation umfasst zwei Teile. Der erste Teil behandelt Invarianzprinzipien für die Diffusion eines Teilchens, das mit einer zufälligen Konfiguration von unendlich vielen anderen Teilchen wechselwirkt, sowie für einen sogenannten "Tagged-Particle"-Prozess. Letzterer beschreibt die Bewegung …

Aural evolutions: intersections of sound with the physical space
This is a practice-based research project situated at an intersection between the fields of electroacoustic composition, experimental composition, and sound art. The general research context for this project is a territory that engages with sound as a physical medium, and is concerned with the …

First-order geometric evolutions and semilinear evolution equations : a common mutational approach
… of "solution" for completely different types of evolutions. Such a common approach is to lay the foundations for solving systems whose components have their origins in diverse applications. The analytical touchstone of the general character consists of (1.) a semilinear evolution equation in a …

Prediction of Microstructural and Conformational Evolutions through Application of Steepest-Entropy-Ascent Quantum Thermodynamics
Steepest Entropy Ascent Quantum Thermodynamics (SEAQT) is a novel theoretical framework unifying quantum mechanics and thermodynamics. This framework employs an equation of motion governed by the principle of steepest entropy ascent to determine the thermodynamic state evolution of modeled systems. …

Modeling and Characterization of Structural, Thermophysical, and Dynamical Evolutions of Small Bodies in the Solar System
… their structural, thermophysical, and dynamical evolutions to provide a more comprehensive view of their life cycle. Asteroids exhibit a remarkable diversity of shapes, reflecting their complex evolutionary pathways. This dissertation begins by exploring their structural condition through the …

A Numerical Study of Three-Dimensional Black Hole Spacetimes
We present results from numerical evolutions of vacuum black hole spacetimes in 3D Cartesian coordinates. We first studied the Schwarzschild spacetime, comparing extensively with 1D studies. We show that although accurate 3D evolutions are possible, there are a number of difficulties in evolving 3D …

A numerical study of 3D black hole spacetimes
We present results from numerical evolutions of vacuum black hole spacetimes in 3D Cartesian coordinates. We first studied the Schwarzschild spacetime, comparing extensively with lD studies. We show that although accurate 3D evolutions are possible, there are a number of difficulties in evolving 3D …

Numerical Simulations Of Black Hole Binaries: Second Order Spectral Methods
… a new penalty method for pseudo-spectral evolutions of second order in space wave equations. The penalties are constructed as functions of Legendre polynomials and are added to the equations of motion everywhere, not only on the boundaries as is typical in first-order formulations. …

Quantum computational chemistry methods for early-stage quantum computers
… correspond to a product of unitary evolutions of fermionic excitation operators. Owing to their fermionic structure, UCC ans\"atze preserve the symmetries of electronic wavefunctions, and thus are accurate and easy to optimize. Nevertheless, UCC ans\"atze are implemented by high …

Quantum Wiener chaos
… stochastic cocycles and quantum stochastic evolutions. The corresponding quasifree case is also studied and the constructions extended to fit in that formalism. We construct the multiple quantum Wiener integral as one operator on a family of operators which we dub operator kernels. This in …

Molecular Evidence Suggests Multiple Evolutionary Origins of Sociality in the Polyphenic Spider <em>Anelosimus studiosus</em> (Araneae: Theridiidae).
… or 2) pockets of social behavior represent local evolutions, thus leading to multiple origins of evolution. Microsatellite loci were used to determine genetic structure of the population and to estimate the origins of social behavior. All loci showed lower observed than expected heterozygosities …

Functional inequalities in quantum information theory
… properties of certain quantum Markovian evolutions. In this thesis, we study various extensions and problems arising from the specific noncommutative nature of such processes. The first logarithmic Sobolev inequality to be proved, due to Gross, was for the Ornstein Uhlenbeck semigroup, …
