Expanding the breadth and detail of object recognition
Object recognition systems today see the world as a collection of object categories, each existing as a separate isolated entity. They exist in a closed world, never expecting to come across a new and unfamiliar object. This bleak view of the world leads to brittle systems that are limited to …

Diet Breadth Evolution and Diversification of a Generalist Insect Herbivore
… plants (bottom-up) influence an herbivore's diet breadth. In my meta-analysis evaluating the relative important of top-down and bottom-up forces on insect herbivore fitness, I found that herbivores usually have greater performance on better quality plants and in the absence or reduction of enemy …

Expanding the accuracy, resolution, and breadth of cell-free DNA investigation
… resolution, imperfect accuracy, and constrained breadth. Taken as a whole, these factors restrict the set of conditions that might in principle be detected or monitored with this molecular evidence. In this dissertation, I directly address these limitations with the goal of expanding the scope …

Design and analysis of a nondeterministic parallel breadth-first search algorithm
… have developed a multithreaded implementation of breadth-first search (BFS) of a sparse graph using the Cilk++ extensions to C++. My PBFS program on a single processor runs as quickly as a standard C++ breadth-first search implementation. PBFS achieves high workefficiency by using a novel …

The Relationship Among Organizational Justice, Trust, and Role Breadth Self-Efficacy
… and trustâ contribute to the enhancement of role breadth self-efficacy (RBSE), a form of proactive behavior. The sample consisted of 226 white-collar professionals in large and small organizations. Approximately 70% held a college degree. An a priori path model based on theoretical literature was …

Arthropod Predation in Brassica Agroecosystems: Effects of Latitude, Community Composition, and Diet Breadth
… this gradient extends to agroecosystems. Diet breadth of an arthropod predator can influence whether a predator can adequately control resident herbivore populations and can impact predation in a community context by determining whether predatory taxa will compete over shared prey, attack each …

Effects of resveratrol on development of three lepidopteran species varying in diet breadth
The polyphenolic stilbene resveratrol is a plant secondary compound associated with antioxidant and anti-pathogen functions. Knowledge of these functions prompted longevity and development studies on many different model organisms, including several insect species. Results from these studies have …

Historical and Geographic Context for the Evolution of Climate Niche Breadth in Temperate Plants
… Niche theory provides a useful framework. Niche breadth describes the range of environmental conditions necessary for population growth. Among these conditions, climate is especially important. Climate niche breadth in turn may reflect a confluence of different forces. This dissertation presents …

On the Breadth of the Jones Polynomial for Certain Classes of Knots and Links
The problem of finding the crossing number of an arbitrary knot or link is a hard problem in general. Only for very special classes of knots and links can we solve this problem. Often we can only hope to find a lower bound on the crossing number Cr(K) of a knot or a link K by computing the Jones …

Taking a Deep Breadth: The Rhetorical Construction of Solidarity in the American Labor Movement
<p>This dissertation explores the rhetorical fragments in three case studies of the American Labor Movement constituting movement members in solidarity. Using Kenneth Burke's discussion of rhetorical substance, this project explores the possibilities for developing deep and broad forms of …

Characterising the magnitude and breadth of T cell responses to SARS-CoV-2 vaccination
… only a few studies have characterised their breadth of targeting across the spike. This characterization is crucial for predicting cross-reactivity in T cell responses against emerging variants of concern (VOC) that may have mutations in the targeted regions. This study aimed to examine the …

The relationship between niche breadth and geographic range size in African Horseshoe bats (Rhinolophidae, Chiroptera)
… Brown's hypothesis, generalists have high niche breadth and can tolerate a wide variety of environmental conditions resulting in large geographic range sizes. Conversely, specialists have low niche breadth and small range sizes. I tested this hypothesis using African Horseshoe bats to determine …

The Roles of Scene Characteristics, Memory and Attentional Breadth on the Representation of Complex Real -World Scenes
… 1 investigated the role of attentional breadth and change characteristics in perceptual change detection performance. Experiment 2 expanded the objectives in Experiment 1, by additionally examining the possible effects of inhibition, perceptual speed, working memory and scene context on …

Character displacement in Burkholderia biofilm communities and the effect of adaptive history on the evolution of niche breadth
<p>Ecologists agree that biodiversity is essential for maintaining highly productive and stable ecosystems, yet the mechanisms that generate and preserve diversity are unknown in many habitats. Competition for shared resources may cause selection to favor niche specialization, which reduces …
