Adiabatic excitation of multilevel systems
Physical Review A, 1985We derive and discuss the behavior of several multilevel models relevant to the problem of molecular multiphoton excitation under the action of a quasimonochromatic laser field, the amplitude of which rises slowly and falls rapidly on a certain internal time scale.

Emulation of IEEE Excitation System Models Using Micro-Alternator’s Excitation System
2020 IEEE 29th International Symposium on Industrial Electronics (ISIE), 2020This paper proposes an approach to emulate the behaviour of different IEEE excitation system models or industry provided excitation system models using a micro-alternator in the laboratory. An IGBT based buck converter is used as an exciter for the alternator.

Controllability of Excitable Systems
Bulletin of Mathematical Biology, 2001Mathematical models of cell electrical activity typically consist of a current balance equation, channel activation (or inactivation) variables and concentrations of regulatory agents. These models can be thought of as nonlinear filters whose input is some applied current I (possibly zero) and output is a membrane potential V. A natural question to ask

Excitation and Conduction in the Nervous System
Annual Review of Physiology, 1953It is appropriate to open this review by recording the death of Sir Charles Scott Sherrington, on March 4, 1952. The great indebtedness of neurophysi ology to him and to his students is amply recognized and has been sketched by one who knew him well (63).

Exciters and Systems of Excitation
Transactions of the American Institute of Electrical Engineers, 1920IN laying out excitation systems for central power stations continuity of service is the primary requirement. First cost and economy in operation are secondary requirments which must be given due weight.

Solitonlike excitations in biological systems
Physical Review A, 1985A model for solitonlike excitation in DNA is presented and assessed in the context of previous models of collective excitations in other biological systems. A qualitative analysis describes the mechanisms of some DNA function, in particular opening of DNA base pairs to initiate protein synthesis.

Chaotic Behavior in Excitable Systems
Annals of the New York Academy of Sciences, 1990This paper has dealt with biophysically accurate, or plausible, excitation systems. These are obtained from experiments, and so are complicated, often of high order, and are continually being updated by new experimental results. This is especially true for the excitation equations that represent cardiac tissue.

Muscle fiber excitation system
2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016Persons unable to exercise due to old age, immobility or medical condition may develop low bone density, decline in muscle contraction, blood pooling or clot. Due to musculoskeletal fragility caution is required in bone and muscle strengthening. Similarly, caution is required to use anticoagulant drug to prevent blood clot due to side effect, and ...

Excitable chemical reaction systems I. Definition of excitability and simulation of model systems
Journal of Mathematical Biology, 1975Using a computer program based on the well-known Crank-Nicolson method, a number of onedimensional chemical reaction-diffusion systems showing “regenerative excitability” are simulated, both on a finite interval and on a circle. Hereby several phenomena known from nerve physiology as travelling trains and pulse omissions have been reproduced.

Excitation Spectrum of a Fermion System
Journal of Mathematical Physics, 1962By the method of ``modes'' introduced by Sawada, the excitation spectra of a fermion system with singular interactions have been obtained in three cases; (1) with one additional particle above and and one hole below the Fermi surface, (2) with one additional particle above the Fermi surface, and (3) with two particles above the Fermi surface.
