Ecosystem responses to precipitation extremes
… changing frequencies and intensities of climate extremes have prompted ecologists to increasingly study their ecological impacts. Rising interest in this field of research reflects growing recognition that changing climatic variability can impact ecological dynamics independent of climatic means, …

Transformed-linear models for time series extremes
… the class of possible TPDFs. We also develop an extremes analogue of the classical Wold decomposition. Simulation study shows that our class of models provides adequate models for the GARCH and another model outside our class of models. The transformed-linear innovations algorithm gives us the …

Assessing and modelling extremal dependence in spatial extremes
… two types: asymptotic independence (AI) when the extremes at the two sites are unlikely to occur together, and asymptotic dependence (AD) when it is possible for both sites to be affected simultaneously. For finite samples it is often difficult to determine which type of dependence the data are …

Essays in Climatic Extremes, Agriculture and Natural Resources
… assessments are carried out of changes in extremes of rainfall. These putative changes are then assessed in relation to certain larger scale climatological phenomena which presumably impact hydrologic extremes, based on hypotheses presented in the literature. The second part of the …

Taming TinyML: deep learning inference at computational extremes
The advanced data modelling capabilities of neural networks allowed deep learning to become a cornerstone of many applications of artificial intelligence (AI). AI can be brought into our environments by deploying neural models to ubiquitous Internet-of-Things (IoT), wearable and embedded devices to …

Going to extremes : an investigation into consumers' excessive behaviours
[Essay 1] Empirical evidence has suggested that individuals adopting a maximizing decision-strategy (“only the best will do”) are victims of a “paradox”, in that the effort they expend to enlarge their choice sets and search for the best option ultimately imperils their wellbeing. However, recent …

Reaction of Tardigrades (Hypsibius) to Physical and Chemical Extremes
<p>The process of cryptobiosis is characterized by a complete state of body water dehydration and undetectable metabolic activity, which allows tardigrades {Hypsibius) to escape environmental stress when conditions become unfavorable. In our research, Hypsibius was tested in a laboratory under pH …

Evaluating Adaptive Capacity to Climatic Extremes in Rural Zambia
… strengthen their adaptive capacity to weather extremes. After reviewing the literature on how climatic extremes impact welfare in the first chapter, the second chapter uses a systematic review of randomized and non-randomized studies to evaluate the effectiveness of policy interventions in …

Materials At Extremes: Shock-induced Fracture and Phase Transitions
Owing to the high-pressures and strain-rates associated with shock waves, their study is of great interest to a host of different fields including, but not limited to, planetary sciences, medical applications, sports science, aerospace engineering, chemistry, and materials science. Most broadly, …

Nerve Cross Sectional Area in Extremes of Height and Weight
Introduction: Cross-sectional nerve area reference values have been reported for many populations including pediatric, geriatric, and middle-aged, however few studies have investigated extremely tall and heavy individuals. Previous studies are conflicting; some suggest height and others weight as …

Climate extremes over the Mid-Atlantic states: a regional approach
… no longer be applicable, as historic records for extremes such as heat waves and floods may no longer accurately predict the changing future climate. To assess extremes (present-day and future) over the contiguous United States, I used NOAA’s Climate Extremes Index (CEI), which evaluates extremes …

Three Essays on Extremes and Non-Linearities in Asset Pricing
The dissertation consists of three self-contained essays, with a focus on empirical capital market research. The first essay "Time-Varying Conditional Market Returns: Is Variance or Tail-Risk Priced", empirically investigates the question whether there is a positive relationship between aggregate …

Painting life in extremes Charles Maturin and the Gothic genre
Charles Robert Maturin (1780-1824) produced a substantial body of writing that included six novels, three plays, and two collections of sermons. Despite the large audience he reached in his own time, and the interest he aroused in a number of later poets and novelists, Maturin's work has not …

Changes in hydrological extremes and climate variability in the Severn Uplands
Hydrological extremes within the UK have increased in intensity, frequency and<br/>persistence over recent years and are predicted to increase in variability throughout the 21st<br/>century. Past and future changes in hydrological extremes relative to climate change were<br/>investigated within …
