An Examination of Two Possible Delineations of the REMS-Consolidation Hypothesis.
… in the 1950's demonstrated that sleep was not a homogeneous state, in fact, that it consisted of periodically recur- ring stages (Aserinsky and Kleitman, 1953). One of these stages is readily identifiable due to concurrent physiological changes: elevated temperature, increased metabolic rates, …

Topics in stringy cosmology
… properties at early times. We first study the state space of inflationary braneworld models with exponential potential and identify the past and future attractors within the homogeneous state space. Our main result is that the isotropic high energy BDL model is the generic past attractor in the …

Contributions to mixing and hypocoercivity in kinetic models
… the Vlasov–Poisson equation around the spatially homogeneous state. For the Kuramoto equation, I cover the linear analysis around general stationary states and show nonlinear stability results with algebraic and exponential decay. Moreover, I show how the mean-field estimate by Dobrushin can be …

Bayesian singular spectrum analysis with state dependent models
… may lead to degraded forecasts. In this thesis a state dependent model is proposed under the assumption that if a system moves from one homogeneous state to another rapidly that this transition may be tracked using a Bayesian model in which the state transitions are state dependent. In addition, …

Numerical simulation and modeling of two-phase flows using the volume-of-fluid method
… regime, the bubble swarm does not reach a homogeneous state. As the density ratio is increased, the centroid of the bubble swarm was found to deflect away from the center and closer to the wall. This effect is less deterministic upon varying the initial bubble distribution. Before …
