Stroke patients and family members should receive stroke education including recognition of stroke symptoms and prompt activation of emergency medical services (EMS). The impact of this education is unclear. We aimed to measure the associations between EMS use and timing of hospital arrival and first-ever and recurrent strokes as a proxy for stroke ...

The sequence of excitation of cardiac muscles is greatly affected by any abnormality in the conduction system of the heart. Epicardial mapping for the measurement of activation time at different points is helpful for the diagnosis of such abnormalities.

The problem of finding proper quantal operators for the time of arrival, when the source is at infinite distance from the detector, is investigated. It is shown that at least two Hermitian operators can be constructed which, in the Hilbert space of positive energy spectrum, are self-adjoint.

Finding optimal paths in stochastic networks is an important topic in many scientific and engineering fields. To cope with uncertainty, various performance measures, including expected travel time, reliability, value at risk, and expectation with chance constraint, have been introduced.

A femtosecond electromagnetic pulse propagating in a linear dispersive medium is analyzed in phase spaces of (space, wave number) and (time, frequency). First moment densities are computed as eigenvalues of differential operators acting on Hilbert ray representations of the pulse in relevant domains.

Abstract A simple derivation, using Bohm trajectories, is given of Dumont and Marchioro's expression for the distribution of arrival times of transmitted particles at a point on the far side of a 1D barrier. Calculated distributions are presented and the “quantum speed-up effect” discussed from the Bohm trajectory viewpoint.

Abstract When, at two o’clock in the afternoon on the next day, Natividade boarded the trolley to go on I don’t know what shopping errands at the Rua do Ouvidor, she carried the phrase with her. The view of the bay did not distract her, nor the people passing by, nor the bumps of the street, nothing.

Poisson Arrivals See Time Averages
Operations Research, 1982In many stochastic models, particularly in queueing theory, Poisson arrivals both observe (see) a stochastic process and interact with it. In particular cases and/or under restrictive assumptions it has been shown that the fraction of arrivals that see the process in some state is equal to the fraction of time the process is in that state.
