Capillary Electrophoresis With Amperometric Detection for Neurotransmitter Analysis: Principles, Electrode Materials, Methodologies, and Applications

ELECTROPHORESIS, EarlyView.
This review provides a comprehensive summary of monoamine neurotransmitter analysis by capillary electrophoresis with amperometric detection. Fundamental principles of amperometric detection, electrode positioning strategies, and approaches to high‐voltage decoupling are described, followed by a critical comparison of electrode materials, selection of ...

Quantitative electroencephalographic measures during postmalarial epileptogenesis

Epilepsia, EarlyView.
Abstract Objective Severe malaria with neurologic involvement contributes significantly to the global burden of acquired pediatric epilepsy. We studied quantitative electroencephalographic (EEG) measures in postmalarial epileptogenesis. Methods A total of 186 patients, aged 6 months to 11 years, with confirmed central nervous system malaria were ...

Creativity and its link to epilepsy

Epilepsia Open, EarlyView.
Abstract Creative thinking represents one of our highest‐order cognitive processes, involving multiple cortical structures and an intricate interplay between several cortical and subcortical networks. It results in novel ideas that translate to useful products or concepts. The evolutionary purpose of creativity is therefore apparent, as it advances our

Robust disturbance rejection

Proceedings of 1995 34th IEEE Conference on Decision and Control, 2002
The problem of robust asymptotic disturbance rejection for systems involving parametric uncertainties is studied. A design method is proposed that is based on polynomial techniques. Various uncertainty structures are considered including single and multiple parameters as well as affine, polynomic and even non-polynomic cases.

Fractional active disturbance rejection control

ISA Transactions, 2016
A fractional active disturbance rejection control (FADRC) scheme is proposed to improve the performance of commensurate linear fractional order systems (FOS) and the robust analysis shows that the controller is also applicable to incommensurate linear FOS control.

On perfect disturbance rejection

Proceedings of 32nd IEEE Conference on Decision and Control, 2002
A new observer-based approach to perfect disturbance rejection in linear continuous systems is introduced. A technique of continuous deadbeat observation is exploited to estimate the disturbance signal described by a known dynamic model. A realization condition in the form of linear algebraic equations is derived.

Adaptive disturbance rejection

[1991] Proceedings of the 30th IEEE Conference on Decision and Control, 2002
Using averaging analysis a novel direct adaptive algorithm applied to a linear plant is analyzed. The prior knowledge includes a nominal model and a stabilizing controller for the plant. It is shown that the stabilizing controller can be augmented with an adaptive controller solely aimed at disturbance rejection/trajectory following. The overall scheme

Steering Torque Disturbance Rejection

SAE International Journal of Vehicle Dynamics, Stability, and NVH, 2017
<div class="section abstract"><div class="htmlview paragraph">The layout of a vehicle steering system has to resolve a compromise. While it is important for lateral vehicle control to feel steering torque feedback of lateral tire to ground interaction, disturbing forces shall not be present in the feedback steering torque.

Decoupling and disturbance rejection

IEEE Transactions on Automatic Control, 1975
For the linear multivariable system \dot{x} = Ax + Bu + Er, z_{i} = D_{i}x(i \in k), x \in X , with disturbance \Gamma(\cdot) , it is shown that the decoupling problem and disturbance rejection problem are simultaneously solvable, so as to yield a stable closed-loop system, if and only if Im(E)\subset V_{g}^{*} and R_{i}^{*} + \ker D_{i} = X, i \in k .
