Functional consequences of rapid evolution at Drosophila centromeres
… encode essential centromeric proteins evolve rapidly in plants and animals. However, the selective forces driving the rapid evolution of centromeres and the functional consequences of such rapid change are not well understood. I aimed to gain insight into the functional consequences of …

Formalism for the rapid evolution of primordial black holes
… on early work by Misner and Sharp, is for the evolution of a perfect fluid in spherical symmetry under its own gravity. This allows us to efficiently determine if a black hole will form, but due to the formation of a singularity, it does not allow us to extract the black hole's mass. The …

The Evolution of Recombination Landscapes and Mechanisms in Drosophila in Light of Intragenomic Conflict
… that selection acts upon and, thus, facilitates evolution. However, meiosis provides an arena for manipulation and exploitation by selfish genetic elements. Selfish elements can increase in abundance independently of their host organism and frequently at a cost to host fitness. Several types of …

Context-aware handoff support for wireless access networks
… This computing platform has been driven by the rapid evolution of mobile devices that are equipped with multiple network interfaces and the development of IP based applications.

The evolution of prezygotic reproductive isolation in the Drosophila pseudoobscura subgroup
… subgroup. I begin by evaluating how the evolution of female preferences and male sexual characters lead to reinforcement between Drosophila pseudoobscura and its congener D. persimils. In particular, I will evaluate two alternative hypotheses; Preference Evolution and Discrimination …

Causes and consequences of color polymorphism in Rambur’s forktail (Ischnura ramburii)
… in countless animal taxa, and has fascinated evolutionary biologists since Darwin and Wallace. The underpinnings of male variation have been elucidated in diverse groups; less is known about the selective forces that diversify female forms in nature. Female-polymorphic damselflies provide …

Signatures and forgeries: optimality in a coevolutionary arms race
… antagonistically, ‘arms races’ played out on coevolutionary battlegrounds can drive the rapid evolution of intricate and complex adaptations in each species. However, evolution in one species may prevent optimality in these adaptations from being realised in the other. In the Choma District of …

Paleomagnetic Investigation of Enstatite Chondrite Chondrules: Implications for the Solar Nebula
… solar system formation were characterized by the rapid evolution of the protoplanetary disk. A magnetic field governed the highly efficient mass and angular momentum transport systems. Paleomagnetic measurements of chondrites have constrained the intensity of the nebular field between ∼3-7 AU. …

Evolution at the edge: how hibernation, heat waves, and hybridization impact a range expansion
Evolutionary processes shape the diversity of life on earth. Over millennia, species diverge from one another, radiating out into the tree of life. The same processes of evolution are also acting in much shorter periods of time, selecting for traits, mixing genes across populations, and generating …

Assessing Photoelectric Fusion Technologies: Market Potential and Strategic Insights from NTT's IOWN Case
This thesis investigates the rapid evolution of technology in response to surging internet traffic, projected to increase from 33 zettabytes in 2018 to 175 zettabytes by 2025, and data processing demands, anticipated to exceed 180 zettabytes by the same year. The escalating requirements for more …

Product and program management : battling the strangler trees of system and social complexity in the software market jungle
… of software products, demonstrating the rapid evolution of a field facing unprecedented problems with product complexity and motivating the need for Product Management. The role of Product Manager is explored in detail using both extant literature and interviews conducted with current …

A Selection for Intein Splicing inPhage Assisted Continuous Evolution
… backbone. This has motivated engineering and evolution of bespoke intein properties, including extein constraints, split site, kinetics, and orthogonality. Rational approaches are highly biased and preexisting directed evolution methods are laborious and often struggle with guaranteeing …

Evolution of antiviral breadth in Mx GTPases
… hosts are engaged in a constant battle to gain evolutionary dominance. Such host-virus "arms races" drive the rapid evolution of genes in conflict to gain a fitness advantage through recurrent innovation. Herein, I leverage evolutionary signatures of these adaptive processes to gain insight into …

Deploying the right technology : a framework for digital strategy and selection at the United States Postal Service to shape the future of work
With the rapid evolution of technology from more affordable hardware and data storage to artificial intelligence, companies must evolve their technology strategy to remain relevant. Federal agencies are no exception as they continue to deploy transformational technology to improve services for the …

An Access Control Model for NoSQL Databases
… which were just network scale. There has been a rapid evolution in computing paradigm that has created the need for data storage as agile and scalable as the applications they support. Relational databases with their joins and locks influence performance in web scale systems negatively. Thus, …

Host Modulators of the Death Response to Influenza A Infection
… as vaccines require yearly development and the rapid evolution of viral proteins gives rise to drug resistance. In consequence additional intervention strategies, that target host factors required for the viral life cycle, are under investigation. Here I employed arrayed whole-genome siRNA …

Fast-track packages in colorectal surgery: an examination and development of the evidence supporting their use
… or Enhanced Recovery packages have shown rapid evolution and widespread introduction to colorectal units throughout Europe and the United States of America. The 'fast-track' approach prescribes a 'multi-modal' and 'multi-disciplinary' package of care to guide the pre-operative, …

The PCF and the question of intellectual workers : the crisis of social ideology
… a debate is that in a society given to both a rapid evolution of its social structure and an increased polarisation between Left and Right, a precise knowledge of the objective and subjective determinations of new strata would enable parties to the Left to make proper distinctions between …

Evolution of the mobile phone supply chain : the case of Ecuador
… supply chains. Ecuador is no exception, and the rapid evolution of the industry over the last decade has led to various changes in the supply chain of mobile devices. This thesis characterizes the supply chain challenges faced by the cell phone industry in Latin America. Key challenges …

Storm mergers and their role in tornado genesis during the 2011 Joplin storm
… result in local conditions more favorable for rapid intensification of vertical vorticity at the surface than found in the surrounding environment. Following the work of Lemon (1976) and Lee et al. (2006), this study uses high-resolution WRF simulations to simulate and understand the …
