The aim of the research presented in this thesis is to generate compact, lightweight, low-energy, reversible, and dynamic burrowing systems for use in subsea applications such as anchoring, oil recovery, underwater cable installation, mine detonation, and sensor placement. As many organisms have evolved to embed themselves within undersea substrates,(More)
— A mobile system's maneuverability describes the scale and span of the velocities with which it can move. In this paper, we present a new geometric framework for describing the maneuverability of kinematic locomoting systems, inspired by the manipulability analysis of robotic arms. This framework describes both the local maneuverability in the neighborhood(More)
In preparation for evaluating hormone effects and hormone receptor gene influences on fundamental processes of behavioral arousal, we subjected 48 ovariectomized female mice to a rigid protocol of several tests bearing on arousal concepts. The central hypothesis was that results would organize themselves according to capacities for sensory alertness, motor(More)
Despite the inherent difficulty of connecting individual genes with integrated mammalian behaviors, it has been determined that a series of genes are turned on by estrogenic hormones acting in forebrain. Their products are, in turn, facilitatory for female reproductive behaviors such as lordosis. The causal routes by which two genes contribute to the(More)
We present the results of a recent collaboration between scientists, engineers and chefs. Two particular devices are developed, both inspired by natural phenomena reliant on surface tension. The cocktail boat is a drink accessory, a self-propelled edible boat powered by alcohol-induced surface tension gradients, whose propulsion mechanism is analogous to(More)
Neuro-sensory systems are critical for integrating environmental stimuli and providing a framework for resolving decision-making tasks. Remarkably, the molecular mechanisms mediating transduction of sensory information in neu-rons are also found in other cellular tissues, including sperm. One mechanism facilitating such behavior is a sperm's ability to(More)

In this thesis, we conduct research toward understanding coupled physics-biology processes in ocean straits. Our focus is on new analytical studies and higher-order simulations of idealized dynamics that are relevant to generic biological processes. The details of coupled physics-biology models are reviewed and an in-depth global equilibrium and local(More)
