While microbial competition during infection has most often been examined at the genus or species level [1, 2], the dissertation work described herein asked whether interstrain competition plays an important role in determining which bacterial lineages emerge to cause disease. The goal of this dissertation was to examine the strain...
When a collection of individual units behave synchronously, it is often useful to describe the actions of the group. Broadly speaking in Physics, individuals are described as particles and collective actions are described using waves. However, the dynamic symphony of life ordains that orchestral sections play in harmony for a...
Despite its demonstrated effectiveness, exposure therapy – repeatedly approaching a fear/anxiety trigger – is not widely used in the treatment of anxiety disorders. This may be due to its image as an aversive (and even harmful) approach to treatment and its reduced rates of compliance among patients. However, if exposure...
Molecular self-assembly is a process in which molecules spontaneously form ordered aggregates, the process of which is important in the natural world, considering those ordered systems and complex architectures contained in a living cell. The goal of chemists is to design simple molecules or chemical systems that can undergo molecular...
A significant portion of material science research is concerned with understanding theway that defects affect the properties materials. In the field of thermoelectrics introducingor removing point (0D), dislocation (1D), grain boundary (2D), or precipitate (3D) defectsare popular methods for altering a materials thermoelectric efficiency. Herein I discussdifferent studies conducted during...
Formed through self-assembly of polynuclear node clusters and multitopic organic linkers, metal–organic frameworks (MOFs) are a class of three-dimensional crystalline materials. Due to their exceptional porosity, high surface areas, amenability to construction, chemical diversity, uniformly arrayed metal-containing nodes, and highly modular nature, MOFs are an ideal class of materials for...
Pragmatic language refers to the use of language in social contexts and encompasses a broad range of verbal and nonverbal skills, which are critical to effective communication (Berko-Gleason & Bernstein-Ratner, 2009; Mey, 1993). Difficulties in pragmatic communication are a hallmark characteristic of autism spectrum disorder (ASD). Similar deficits are also...
This dissertation describes modifications to the surface of colloidal semiconductor quantum dots (QDs) to improve their use as photocatalysts for charge transfer reactions. The surface atoms and ligands of these nanoparticles can interfere with direct charge transfer to a reagent by inhibiting binding, forming trap states, or acting as competitive...
Understanding the photophysical processes of organic materials is important for utilizing them as functional photonic materials. Typical photophysical processes include intersystem crossing, charge transfer (CT), symmetry-breaking charge separation (SB-CS), singlet fission (SF), etc. There are serval factors that can lead to different photophysical processes, such as the molecular energy levels,...
During influenza A virus (IAV) infection, severe lung injury and death result from an exuberant host inflammatory response, or “cytokine storm”, orchestrated by pulmonary epithelial cells. The linear ubiquitin assembly complex (LUBAC), composed of SHARPIN, HOIL-1L and HOIP, is a critical regulator of NF-κB-dependent inflammation. To determine the impact of...
