Biochemical Separation of Geographical Strains of Plum Curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), and Evaluation of Olfactory Attractants in Virginia Orchards
… strains. Of the tested primers four, OPE 01, OPE 03, OPE 04, and OPE 07, gave 21 amplimers that are useful for distinguishing individuals from the univoltine and multivoltine populations. Gene targeted PCR revealed the presence of Wolbachia in both populations. Analysis of the wsp gene …

Benchmarking Reinforcement Learning and Off Policy Evaluation for Medical Decision Making
… no standardized benchmark has yet been developed. To address this gap, this thesis introduces Episodes of Care (EpiCare), a benchmark designed to mimic the challenges associated with applying RL to longitudinal healthcare settings. I leverage this benchmark to test seven state-of-the-art …

Applications of QCD sum rules at finite temperature
… QCD analytically. This technique is based on the Operator Product Expansion (OPE) and Cauchy's Theorem in the complex energy plane. OPE factorizes the short and long distance interactions where the former are calculated using perturbative theory, and the latter are parameterized in terms of the …

Structural Influences on the Photochemistry and Photophysical Properties of p-Phenylene Ethynylenes: Aggregation Effects and Solvent Interactions
… due to their solubility in water, sensing properties, and biocidal activity against bacteria, viruses, and fungi. A series of oligomers based on these polymers were synthesized (OPEs), and several interesting questions about their photophysical and biocidal properties were raised by earlier …

Single π° production in proton-proton interactions at 2.8 Bev/c
… agreement with the One Pion Exchange (OPE) model. The Treiman-Yang test has been applied to test the validity of OPE. The nearly isotropic distribution of the Treiman-Yang angle is indicative of the fact that one pion exchange is by far the predominant interaction mechanism. The Dalitz …

Crystal engineering of novel organic-inorganic compounds of N- and O-donor dipyridyl ligands
… (BPE) and 1,2-di(4-pyridyl)ethylene (OPE) Compounds prepared were characterised by x-ray diffractometry. Thermal analysis (thermogravimetry (TG), differential scanning calorimetry (DSC) and hot stage microscopy (HSM)) was used to determine the thermal behaviour of these compounds. …

Multiparty Protocols for Tree Classifiers
… We start with Order-preserving encryption (OPE) which allows encrypting data, while still enabling efficient range queries on the encrypted data. However, OPE is symmetric limiting, the use case to one client and one server. Imagine a scenario where a Data Owner (DO) outsources encrypted …

Orbital Polarization in Relativistic Density Functional Theory
The description of the magnetic properties of interacting many-particle systems has been one of the most important goals of physics. The problem is to derive the magnetic properties of such systems from quantum mechanical principles. It is well understood that the magnetization in an atom described …

EXPLORATIONS IN QUANTUM GRAVITY AND CONFORMAL BOOTSTRAP
… microcausality and isolation of the ANEC in the OPE of primary operators in the lightcone limit. I discuss a no-go theorem for massive higher spin particles in chapter three. The no-go theorem is established on analytic properties of the S-matrix in the Eikonal limit. In chapter four, I explore …

Dynamic mode decomposition with application to optimal control
… model constructed from data acquired at a single operating point may not be robust to changes in control inputs or boundary conditions, thereby limiting the model’s utility in control. In order to evaluate the quality of a given data set, we use a condition called Persistence of Excitation (PE). …

Development of a new test protocol for the permit Ion migration test
… (called the Permit ion migration test) was developed at Queen's University Belfast in the late 90s. The validity of this test was established for concretes containing normal Portland cement, by comparing the in situ migration coefficient with both the coefficient of diffusion (from both steady …

Development and applications of novel optimal control algorithms
… a dynamic optimal control technique known as DISOPE. so as to make it attractive on one hand for its implementation in the process industry and, on the other hand, as a novel nonlinear optimal control algorithm. The main feature of the technique is that it has been designed so as to achieve the …

The oppositional gaze: contemporary image-making practice and the implications of skin colour ideals
The thesis explores the uneven distribution of power between and of the black/white female dichotomy and, while using them as a strategic tool within the visual work, questions the implications of skin colour in constructions of femininity within visual representations. Historically as a marker of …

Landscape and environmental controls on soil organic matter decomposability in the High Arctic
I employed 90 day-laboratory soil incubations, proximate carbon fraction analysis, diffuse reflectance infra-red Fourier transform spectroscopy (DRIFTS) and Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy to explore how variability in vegetation and soil moisture across the High …

Light Scattering Study of Aqueous Sucrose Solutions
Aqueous sugar solutions are good cryopreservation agents and yet some of these sugars have not been studied extensively. Here we report results of light scattering studies of aqueous sucrose solution at concentrations ranging from 10 wt% to 50 wt%. Photon correlation spectroscopy was performed on …
