Lengthening the timescale reach of molecular dynamics
… biological systems on nanosecond to microsecond timescales. Using MD, researchers can utilize experimental data from crystallography and cryo-electron microscopy to explore the functional dynamics of biological systems. The timescale reach of the molecular dynamics tool is limited by how fast …

Atomistic calculations of rate of long-timescale microstructural evolution
… quantities that require sampling over a timescale too large for traditional atomistic methods to probe. New methods and techniques have to be developed in order to obtain useful information of rate from atomistic simulations. In this thesis, we explore a set of four problems, related to …

Multi-timescale mechanics of an active low-angle normal fault
Detachment faults dipping < 30° commonly accrue 10’s of kms of offset and accommodate a large portion of crustal extension in moderately-to-highly extended regions. Slip on these high-offset low-angle normal faults remains perplexing due to their apparent misorientation relative to Andersonian …

Nonlinear filtering of high dimensional, chaotic, multiple timescale correlated systems
… theory for high dimensional, chaotic, multiple timescale correlated systems. The research is motivated by problems in the geosciences, in particular oceanic or atmospheric estimation and climate prediction. As the capability and need to further resolve the physics models on finer scales …

Investigation of Long-timescale Behavior of Positive DC Streamer Coronas
… from the inter-electrode gap over inter-pulse timescales. However, this theory has not been validated, either experimentally or numerically. Most prior works investigating DC streamers have focused on the streamer propagation phase (a few tens of nanoseconds) - few have investigated longer …

A Multi-Region Multi-Timescale Burning Plasma Dynamics Model for Tokamaks
… to the edge and ion orbit loss. The various timescales of radiation and transport processes in different regions are vital to the determination of tokamak operation. A multi-region multi-timescale transport model is developed to simulate burning plasma dynamics in tokamaks. Regions including …

Drainage Timescale Estimates and Storage Change Analysis on A Basin Scale
… travel time depicts the characteristic timescale of the catchment drainage process and is therefore also known as drainage timescale (K). Catchment drainage timescale can be estimated empirically from recession flow analysis as well as from hydraulic theory. Applicability of is critical …

Exploring the timescale limitations of RoboClam : a biologically inspired burrowing robot
… of the animal. This paper tests the theoretical timescale limits for running RoboClam while still achieving the soil fluidization that Ensis achieves. Needle valves were used on the robot's pneumatic control system to vary its expansion and contraction times in a series of tests, then each test …

Understanding long timescale phenomena in atomic systems from accelerated molecular simulation methods
… have limited attempts to capture long timescale dynamics of material systems, such as phase transitions or dynamics of supercooled liquids. This class of phenomena often requires the crossing by thermal activation of large energy barriers, which represent transition states separating …

Characterization of the Intrinsic Neural Timescale Indices as a Reliable Fingerprint of Brain Dynamics
<p>Intrinsic neural timescales (INTs) characterize the persistence of neural activity over time and offer insight into the brain’s temporal hierarchy. This thesis evaluates and compares six autocorrelation-based INT metrics—AR(1) Coefficient (Autoregressive Coefficient at 1), First Zero Lag, Lag at …

Application of All-Atom and Coarse-Grained Molecular Dynamics Simulations to Long Timescale Structural Transitions of Proteins
… MD simulations are limited, however, both in the timescales that they can access (usually on the order of nanoseconds) and by the accuracy of MD potential energy functions and parameters. This thesis presents a series of applications of MD to systems which are generally beyond the reach of such …

Design of the electron spectrometer for the HUNTER experiment and timescale of electron thermalization in liquid Argon for directional detection of WIMP dark matter
Neutrino physics has been going through rapid developments since the particle was first proposed by Pauli. The observation of neutrino oscillations has prompted an investigation of the issue of neutrino mass, with the "seesaw" mechanism garnering theoretical support. The HUNTER (Heavy Unseen …
