Drosophila. Photoreceptors. TRP channels. Cellular signal transduction.
The phototransduction cascade in Drosophila is a prototypical G-protein signaling pathway and many of its components have been well-studied. Early genetic screens identified many of the major proteins involved in this pathway and study over the...
Secondhand cigarette smoke (SHCS) is a serious pollutant that significantly increases the risk for cardiovascular disease (CVD) in millions of people worldwide. A large proportion of those exposed to SHCS are children. Female C57B16 mice were...
'Orthogonal modular forms are algebraic modular forms arising from lattices in quadratic spaces. In this thesis, we define orthogonal modular forms, establish their basic properties, and then apply them to a case of ternary quadratic spaces to...
Nurses -- Health and hygiene. Employee health promotion.
Background. Worksite health promotion programs (HPP) support employees' health behaviors to prevent downstream diseases. Maximizing participation can optimize program impact. Objectives. To assess staff nurses' participation in three HPP - flu...

We begin with a presentation of the current state of Poljak and Turzik's conjecture that a matroid is sticky if and only if it is modular as described in [5] and [1]. We show that all graphic, cographic, and regular matroids must satisfy the...
In the late 1960s, Ihara began work that led to the Ihara zeta function, a zeta function which is defined on a finite graph. This function is an interesting graph invariant which gives information on expansion properties of the graph. It also...
The data presented herein demonstrate the requirement for CD154/CD40 in the development of experimental autoimmune encephalomyelitis (EAE), an animal model for multiple sclerosis. Blockade of CD154/CD40 interactions causes a decrease in T cell and...
This thesis presents two-fluid simulations of forced magnetic reconnection with finite electron inertia in two and three dimensional periodic systems. Reconnection in the system is driven by a spatially localized forcing function, added to the ion...
Metal ions confer structural stability and reactivity to a large number of proteins that use the amino acids histidine (His) and cysteine (Cys) to form stable metal-ligand complexes. The stability of metal-His and metal-Cys interactions and their...
The focus of this thesis is the study of nuclearity and exactness for groupoid crossed product C*-algebras. In particular, we present generalizations of two well-known facts from group dynamical systems and crossed products to the groupoid setting....
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...
Cataclysmic variable stars (CVs) are close, interacting binary systems comprised of a white dwarf and a companion star, which is typically a late-type dwarf star. Their progenitor systems are post common envelope binaries (PCEBs) with a white dwarf...
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...
Robots -- Control systems -- Design and construction. Mobile robots. Robots -- Dynamics.
This thesis examines the issues of vehicle and information dynamics in the control of a multi-robot system using a radial-basis potential function controller. Distributed control of multi-robot systems requires each robot to communicate state...
Partially ordered sets. ; Convex polytopes. ; Representations of groups.
This thesis deals with geometric representations of ordered sets. In a geometric representation, each element of the ordered set is assigned a geometric object, with two elements incomparable in the ordered set if and only if the corresponding...
The problem of moving rigid bodies efficiently is of particular interest in robotics because the simplest model of a mobile robot or of a manipulated object is often a rigid body. Path planning, controller design and robot design may all benefit...
Magnetic nanoparticles are promising candidates for use in biomedical applications as remote sensors of biophysical properties, thermal therapy agents, and detectors of specific biomolecules. Many approaches have been used to model magnetic...
In this thesis we look at several problems that lie in the intersection between combinatorial and multiplicative number theory. A common theme of many of these problems are estimates for and properties of the smooth numbers, those integers not...
I investigated the effects of two contemporary disturbances to soil systems: forest clearing in the northeastern U.S. and climate-driven plant succession in the Arctic. To test the effects of clear-cutting forests on mineral soil carbon (C)...
For ordinary knots in R 3 , there are no degree one Vassiliev invariants. For virtual knots, however, the space of degree one Vassiliev invariants is infinite dimensional. We introduce a sequence of three degree one Vassiliev invariants of virtual...
Toxoplasma gondii is an obligate intracellular pathogen that is able to survive in a range of hosts due to its repertoire of secreted effector proteins. Utilizing the type I and type II Δku80 strains we engineered a collection of targeted knockout...
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...
Since their discovery in laboratory plasmas in the 1920s, Langmuir waves have been observed to be ubiquitous in plasma environments, particularly in space plasmas. From the greater solar wind to planetary foreshocks and the auroral ionosphere,...
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...
How the genome is shaped directly influences how it is expressed. In fact, the genome is organized at many different levels, each imparting specific regulation over transcription. Fundamental principles regulating genome organization are poorly...
The research presented in this thesis tested the hypothesis that uterine epithelial cells (UEC) are selectively responsive to bacteria and pathogen associated molecular patterns (PAMP) and that responses are influenced by estradiol (E 2 ). We...

I tackle the problem of naming and sharing resources across administrative boundaries. Conventional systems manifest the hierarchy of typical administrative structure in the structure of their own mechanism. While natural for communication that...
Post-transcriptional pathways provide a major means of regulating eukaryotic gene expression. Reiterations of the AU-rich element (AURE) located within the 3' UTR of many labile cytokine and proto-oncogene mRNA serve as signals for rapid...
In large and complex networks such as the Internet and road networks, traffic routing is typically decentralized. Users in the network choose their routes independently to minimize their own delay, leading to complicated and nonintuitive outcomes...
Successful completion of the cell division cycle is critical for cellular duplication and survival. There are many regulators and checkpoints to ensure the proper cell cycle progression. Disruption of the machinery involved in completion, error...
