Pacing strategy optimization for time trial cyclists with physiological constraints
… for time-trial cyclists by integrating physiological constraints with course-specific environmental factors. Two complementary methods are developed: one directly optimizes velocity profiles using total energy expenditure as a proxy for current energy, while the other optimizes power …

AUFLIP : teaching front flips with auditory feedback towards a system for learning advanced movement
… of implicit motor learning by analogy, our physiological constraints, and the state of the art in augmented motor learning by feedback. AUFLIP presents and validates a physics simplification of an advanced movement, the front flip, and details the implementation of a wearable system, …

Coarticulation in American Sign Language Fingerspelling
… are discussed in terms of frequency patterns, physiological constraints, and spoken coarticulation models.

Genetic diversity and distribution of the ringed salamander (Ambystoma annulatum) across multiple spatial scales
… geologic time, in conjunction with the species physiological constraints are strong regulators of local population dynamics, and thus the global abundance and distribution of a species. Since shifts in distributions leave lasting effects on the genetic diversity and structure of a species, …

How does temperature affect Fork-tailed Drongo, Dicrurus adsimilis, foraging effort, nestling provisioning and growth rates?
… it remains unclear whether this results from physiological constraints on behaviour, from declining food availability and or access to prey items at high temperatures. In this study, I aimed to identify how temperature affects the foraging and provisioning behaviour of wild Fork-tailed …

Phonological pitch
… levels arise from learnability and perceptual constraints, which can be precisely formalized, that also play a role in nonlinguistic domains. Similarly, the Contiguity Hypothesis is derived from psychoacoustic constraints on discriminating between acoustically similar pitches. Other perceptual …

Salt in the Wound: Trophic Mismatches Emerge Between Macroinvertebrate Secondary Production and Basal Food Resources Along a Salinity Gradient in Central Appalachian Headwaters
… detritivores maintains community biomass. The physiological and trophic mechanisms behind salt-induced community shifts remain debated and largely untested in field experiments. I investigated how functional feeding groups (FFGs) respond to freshwater salinization by measuring macroinvertebrate …

Physiological and Ecological Constraints on the Evolution of Viviparity in Sceloporine Lizards
… purpose of this study was to evaluate putative physiological and ecological constraints on the evolution of viviparity in sceloporine lizards. In Chapters one and two, I investigated the role of in utero oxygen availability as a constraint on the capacity to support embryonic development during …

Exploring the dimensionality of speech using manifold learning and dimensionality reduction methods
… fact that articulatory movement is limited by physiological constraints and thus the speech production apparatus has only limited degrees of freedom. Also, the set of sounds used in human spoken communication is only a small subset of all producible sounds. A number of dimensionality reduction …

Tracking and modelling motion for biomechanical analysis
… approaches. It is capable of supporting constraints for most of the known joint types and it can be extended to solve problems with multiple end effectors, multiple targets and closed loops. FABRIK was compared against the most popular IK approaches and evaluated in terms of its …

The Role of Sirtuin Inhibitors on the Proteomic Responses of the Mussels Mytilus galloprovincialis and Mytilus trossulus to Menadione Induced Oxidative Stress
<p>Global climate change imposes physiological constraints on marine ecosystems that can alter the distribution of intertidal organisms. In one such instance, the native cold-adapted mussel <em>Mytilus trossulus</em> is being replaced along its southern range by the invasive warm-adapted …

Dissecting adult epithelial cell plasticity using a model of oesophageal-to-skin lineage conversion
… – known as cell fate plasticity – extends beyond physiological constraints. When exposed to ectopic cues, epithelial cells can alter their identity as directed by the surrounding microenvironment. A deeper understanding of the mechanisms that govern these changes in cell identity holds great …

Effects of environmental warming on lentic freshwater communities and the behavioral and physiological responses by fishes to warming
… events, shifts toward smaller body sizes, physiological constraints, and changes in behaviors. Warming temperatures can affect aquatic ecosystems through multiple mechanisms simultaneously. Temperature can affect ecosystems through ecological interactions, including both abiotic and biotic …

Methods and good practice guidelines for human joint kinematics estimation through magnetic and inertial wearable sensors
… function is minimized through the definition of physiological constraints. This thesis proposed the methods to accurately estimate the human joint kinematics starting from the MIMU signals. Three main contributions were provided. The first consisted in the design of a comprehensive battery of …
