We pose several adversarial variants of the multi-armed bandit scenario and propose new approaches for their play and analysis. Our casino patron seeks to discover information about an unknown system as a means to long-term payoff -- exploration...
This thesis contains material relating to two separate subjects. The first section determines when the C*-algebra affiliated to a directed graph has continuous trace. We use groupoid methods and the focus is on producing conditions on a graph that...
Objectives: This dissertation comprises three essays on geographic variations in healthcare, and the association between utilization and health outcomes. I first explore associations between outpatient visits and Medicare beneficiaries'...
The advent of hypervisors revolutionized the computing industry in terms of malware prevention and detection, secure virtual machine managers, and cloud resilience. However, this has resulted in a disjointed response to handling known threats...
Clinical medicine -- Decision making. ; Medical informatics. ; Patient participation. ; Osteoarthritis -- Treatment. ; Knee -- Diseases -- Treatment. ; Decision Making. ; Decision Support Techniques.
Problem Statement. Effective patients' decision aids (PtDAs) help patients understand clinical information and reduce decisional conflict. PtDAs that also explicitly provide guidance through four """"Deliberative Steps"""" may achieve additional...
For the most part, research on self-regulation has focused on behavior-control, which is how people self-regulate in the face of immediate urges and temptations (e.g., resisting cookies that are close at hand, or resisting beer that is being freely...
The objective of this thesis was to examine the neural and physiological substrates underlying the processing of aversive information, and how individual differences in anxiety influence these responses. In a series of experiments, we utilized skin...
'The control of waves using periodic structures is crucial for modern optical, electromagnetic and acoustic devices such as diffraction gratings, filters, photonic crystals, solar cells, sensors, and absorbers. We present a high-order accurate...
In this thesis, we consider several problems relating to cyclic subgroups of the group [mathematical equation]. Each element of [mathematical equation] has a unique representative in one of the two intervals [mathematical equation] and...
Renewable energy sources are becoming increasingly important as sustainable alternatives to fossil fuels. One of these renewable sources, cellulosic biomass, is a relatively inexpensive and abundant resource that can be converted into liquid fuels...
A fuller understanding of cost and utilization, per discharge and for all-payers, is needed at the hospital level. I conducted three studies to address this need. In study 1, I examine the amount of variation in costs and LOS per discharge that can...
We provide a theoretical model for a design involving a dc voltage biased Josephson junction (JJ) that strongly drives a high quality factor microwave cavity via the ac Josephson effect. We explore the rich classical dynamics of the resultant...
Violent video games are immensely popular among children and adults, making it crucial to understand how these games affect the thoughts, feelings, and behaviors of those who play them. The present research proposed an account by which video game...
In this thesis, we characterize and enumerate the permutations which are realized by the orbits of signed shifts, a family of discrete dynamical systems on words. The permutations, which are called patterns of the signed shifts, are given by the...
Constructibility (Set theory). Trees (Graph theory).
This thesis investigates possible initial segments of the degrees of constructibility. Specifically, we completely characterize the structure of degrees in generic extensions of the constructible universe L via forcing with Souslin trees. Then we...
Casimir effect. Zero-point field. Electric conductivity. Quantum electrodynamics.
The Casimir force arises from an alteration of boundary condition in vacuum and is often regarded as a manifestation of quantum zero point energy. Considerable progress has been made in the last decade with an impressive achievement of experimental...
We present a number of findings concerning groupoid dynamical systems and groupoid crossed products. The primary result is an identification of the spectrum of the groupoid crossed product when the groupoid has continuously varying abelian...
Polynomials. Finite fields (Algebra). Algebraic functions. Number theory.
The ring of univariate polynomials over a finite field shares many foundational arithmetic properties with the ring of rational integers. This similarity makes it possible for many problems in elementary number theory to be translated 'through the...
The great strength of the C-F bond has enabled fluorocarbons to find many industrial and domestic applications, and makes C-F activation a chemical and technical challenge akin to that of C-H bond activation in hydrocarbons. In our mission to...
Stigma (Social psychology). Aging -- Psychological aspects. Cognition -- Age factors. Older people -- Attitudes.
Extensive research on aging has demonstrated that normal aging debilitates executive function, a system that is critical for regulating stereotypes. However, there is a paucity of research on whether age-related declines to executive function...
Behavior during interracial contact is sometimes positive but often negative. Previous work has examined individual differences, such as racial attitudes and motivations to respond without prejudice, as predictors of behavior during interracial...
Background
Smoking is the number one cause of preventable premature death and disease. Social anxiety disorder is strongly associated with nicotine dependence in adults. The aims of this research were to determine whether social anxiety symptoms...
