A modeling study of the history-dependence of conduction delay in unmyelinated axons
… effect). This dissertation investigates how the history-dependence of conduction delay is generated and the contributions of different ionic currents to conduction delay. This dissertation is comprised of three parts. In the first part, we build a biophysical model that includes several …

Mechanics Analysis of Semiconductor Nanotube Formation Driven By Residual Mismatch Strain
… second objective discusses whether or not the history dependence affects the formation process. It was found that while the enegetics of the process largely dictates the formation characteristics, under special conditions the history dependence in the process may be the source of the …

The structure and spatial distribution of dark matter halos
… a wealth of information regarding its evolution history and environment. In particular, I study halo assembly bias, which refers to the assembly history dependence of spatial clustering for dark matter halos at fixed mass, using observational and cosmological simulation data. Understanding and …

From thought to action
… In the first part, I show that temporal and history dependence contributes to the representation of targets in the ensemble spiking activity of neurons in primate dorsal premotor cortex (PMd). Point process modeling of target representation suggests that local and possibly also distant neural …

Force potentiation as a modulator of contractile performance: Implications for control of skeletal muscle force and energetics of work
… experiments studied the contraction-type dependence for PTP and demonstrated that the enhancement of contractile function was dependent on force level. Surprisingly, in the absence of RLC phosphorylation, skMLCK-/- muscles exhibited significant concentric PTP; consequently, up to ~50% of …

Nonlinear structural design using multiscale topology optimization
… sensitivity formulation, we account for the history dependence of internal state variables. Using these sensitivities and topology optimization, we distribute two elastoplastic materials within a design domain to effectively dissipate the energy in an impact problem.

Dynamic aggregation and dispersal of Escherichia coli under cycles of feast and famine
… (feast) and scarcity (famine) results in history-dependent dynamics whereby the planktonic populations appear to achieve increasing resilience to perturbation, as measured by the maximum apparent growth rate during periods of feast. By varying the frequency and amplitude of feasts we find …

Multiscale physics-based modeling of friction
… models proposed in this work account for loading-history dependence, partial slip, gross slip, nonlinear stiffness and energy dissipation characteristics of frictional contacts. In doing so, the models require no curve-fit or look-up parameters. Instead, the formulations are developed from …

Device design and process technology for sub-100 nm SOI MOSFET's
… Another consequence of floating-body behavior is history dependence in I-V behavior. Rapid switching of terminal voltages induce nearly-negligible changes in body majority carrier content since body majority carriers are trapped by body-source/drain junction diodes. However, the change in body …

Smoothing consumption across households and time : essays in development economics
… another's incomes. I show that the way in which "history" matters can be used to distinguish insurance constrained by hidden income from insurance constrained by limited commitment or moral hazard. This history dependence can be tested with a simple empirical procedure: predicting current marginal …
