Form and function of Poly(A) tails
Central to mRNA metabolism is the poly(A)-tail, a stretch of adenosine nucleotides at the mRNA 3' end. In this dissertation, I investigate the role of the tail in the dynamics of mRNA decay, and describe the predominant mechanisms of decay for thousands of mammalian mRNAs. Next, I examine the …

Heavy Tails and Anomalous Diffusion in Human Online Dynamics
In this dissertation, I extend the analysis of human dynamics to human movements in online activities. My work starts with a discussion of the human information foraging process based on three large collections of empirical search click-through logs collected in different time periods. With the …

Long-range interatomic interactions: Oscillatory tails and hyperfine perturbations
<p>"We study the long-range interaction between two hydrogen atoms, in both the van der Waals and Casimir-Polder regimes. The retardation regime is reached when the finiteness of the speed of light becomes relevant. Provided that both atoms are in the ground states, the retardation regime is …

On Compound Variables and the Asymptotic Behaviour of Their Tails
… Before delving into the results concerning the tails of compound variables, we aim to present an overview about the general theory and treat the average behaviour of compound variables first. We familiarize the reader with rudimentary concepts such as moment and cumulant generating functions. …

Tails through time: leopard population dynamics in the Little Karoo
Large carnivores play a vital role in structuring our ecosystems, yet they face mounting threats such as habitat loss, prey reduction and persecution. These threats reduce their global distribution and impacts their population numbers. Protected areas can offer refuge for large carnivores, however …

The Roles of the Mcm2-7 Tails in Replication Initiation
… and Mcm6 contain long unstructured N-terminal tails, which are unrelated to each other and whose role in replication initiation is not well understood. In the following thesis, I describe the use of reconstituted helicase loading and helicase activation reactions to determine the specific …

Hyperredundant Dynamic Robotic Tails for Stabilizing and Maneuvering Control of Legged Robots
… and stabilization behaviors. Looking to nature, tails assist a variety of animals with these functionalities separate from the animals' legs. However, prior research into robotic tails primarily focuses on single-mass pendulums driven in a single plane of motion and designed to perform a specific …

Tails as Teachers: Animal-Assisted Therapy and Children with Autism Spectrum Disorder
<p>Building on the foundation of past research that highlights the benefits of animal- assisted therapy with a variety of populations, such as the institutionalized, the developmentally disabled and geriatric populations, this study investigated the potential benefits of animal-assisted therapy for …

Real-Time Planning and Nonlinear Control for Robust Quadrupedal Locomotion with Tails
… be added in future work to examine the affect of tails on agile and high-speed motions. Initially, this work presents a unified method in which bio-inspired articulated serpentine robotic tails may be integrated with walking robots, specifically quadrupeds, in order to produce stable and highly …

Analytical Estimation of Value at Risk Under Thick Tails and Fast Volatility Updating
Despite its recent advent, value at risk (VaR) became the most widely used technique for measuring future expected risk for both financial and non-financial institutions. VaR, the measure of the worst expected loss over a given horizon at a given confidence level, depends crucially on the …

Silent tails : giving a voice to the voiceless : animal welfare in narrative literary journalism
This creative project offers three stories that explore the value and objectives of animal welfare using the genre of narrative literary journalism. The project required extensive fieldwork specific for each article, as well as the careful analysis of the style and history of narrative literary …

A Systematic Design Methodology for Articulated Serpentine Robotic Tails to Assist Agile Robot Behaviors
… have begun to explore the application of robotic tails. This thesis will explore the design, optimization, construction, and implementation of an articulated serpentine robotic tail. Numerous serpentine tail prototypes have been designed and tested; however, they have not yet been integrated with …

Tail-biting in growing-finishing pigs with intact tails: evaluating group size and litter origin
… risk factors of tail-biting in pigs with intact tails, using group-level and individual-level approaches, and to evaluate associated welfare outcomes across diverse contexts. Two major research projects were conducted, which are presented across four data-driven chapters that collectively address …

On the Tails of the Trade: Enslaved Women, Slave Traders, and the Households they Shared
Throughout the antebellum period, enslaved women engaged in intimate relationships with white men, some of whom were actually slave traders, upholding the institution that kept them in bondage. While each individual’s experience varied, the origins and subsequent circumstances of these women …

'Bunnies with steel tails?' : an exploration of gender identities within an independent single-sex girls' school
… ethos where girls can be 'bunnies with steel tails', combining traditional femininities with a masculine desire to compete and succeed. Yet the school also reproduces traditional, accepted ways of being feminine that can limit the range of gender identities a girl can adopt. This is partly due …
