Modification and sensitivity of equilibria in partially characterized genetic networks
Engineering intracellular biological control systems, whether to perform artificial functions or to modify existing behavior, requires accurate characterization of genetic networks. Slight errors in characterization lead to significant changes in predicted behavior, and consequently to design …

An Investigation of Three Behavioral Approaches Used in the Treatment of Chronic Muscle Contraction Headaches
The purpose. The purpose of this research was to determine the effectiveness of three behavioral methods (Relaxation Training, Biofeedback, and Systematic Desensitization) of treating muscle contraction headache pain in individual chronic headache patients. Procedure. Nine chronic muscle …

Quantifying Dynamic Stability of Musculoskeletal Systems using Lyapunov Exponents
… stability and the subtleties of the neurocontroller. Variability of kinematic data has been used as a measure of stability but these analyses are not appropriate for quantifying stability of dynamic systems. Response of biological control systems depend on both temporal and spatial inputs, …

Experimental evidnece for hysteresis in the cell cycles of Xenopus Laevis egg extracts
… difference in thresholds implies that the MPF control system is hysteretic and bistable. To measure these thresholds, extracts in interphase or M-phase were supplemented with varying concentrations of non-degradable human cyclin B1 protein. MPF activity was determined by the morphology of sperm …

Visually displayed-EMG biofeedback : training muscle relaxation in hearing impaired children :a thesis ...
… randomly assigned to either an experimental or control condition. Participants in the experimental groups were given five 15 minute EMG biofeedback training sessions. An additional group of 4 adolescents with normal hearing from Marshall Junior High School, Stockton, CA served as a hearing …

A Secure Behavior Modification Sensor System for Physical Activity Improvement
<p>Today, advances in wireless sensor networks are making it possible to capture large amounts of information about a person and their interaction within their home environment. However, what is missing is how to ensure the security of the collected data and its use to alter human behavior for …

Methods of system identification, parameter estimation and optimisation applied to problems of modelling and control in engineering and physiology
… in the development of integrated dynamic systems, such as “control-configured” aircraft or in complex robotics applications. These models usually involve combinations of linear or nonlinear ordinary differential equations or difference equations, partial differential equations and …
