Stimulus response latency is the delay between stimulus onset and the evoked modulation in neural activity. A common technique to estimate latencies involves binning the spike arrival times to form a peri-stimulus histogram. This histogram is smoothed using a fixed bandwidth. The estimated latency is the first time following stimulus onset in which the smoothed histogram exceeds the midpoint be...

BACKGROUND AND PURPOSE Patient delays in seeking treatment for stroke and delays within the Emergency Department (ED) are major factors in the lack of use of thrombolytic therapy for stroke. The Genentech Stroke Presentation Survey was a multicentered prospective registry of patients with acute stroke. The study was designed to characterize prehospital delays and delays within the ED. METHODS...

This paper gives an exact analysis of mean response time of fork-join systems. The response time is shown to be the sum of parallel wait and parallel service times which are analogous to wait and service times in non-parallel systems. It is shown that the parallel service time of a job is dependent on the state at arrival time of the job. A formal parallel wait time analysis, similar to the wai...

This descriptive, hospital-based study, performed in western Turkey, was designed to assess the level of pre-hospital delay and reasons for such delay in acute stroke patients, taking into consideration certain factors such as socioeconomic status, availability of transport options at onset of symptoms. Data were collected from hospital records, and a questionnaire was administered that include...

In many passive localization applications, the reference waveform of received electromagnetic signals is partly known. The in such scenarios are formulated by modelling relationship between data and known signal parameters interest, as time-difference-of-arrival (TDOA) frequency-difference-of-arrival (FDOA). By exploiting prior information carried signal, negative impact random noise can be sig...

We propose an efficient semi‐numerical approach to compute the steady‐state probability distribution for the number of requests at arbitrary and at arrival time instants in Ph/M/c‐like systems in which in the inter‐arrival time distribution is represented by an acyclic set of memoryless phases. Our method is based on conditional probabilities and results in a ...

A time-difference-of-arrival-based partial discharge (PD) location system that utilises prior knowledge of substation layout is presented. We propose a new time delay estimator employs onset detection techniques and demonstrate, through experimental results, it at least 2.8 times more accurate than other conventional estimators. Using substation’s layout, we develop minimum mean-square-error (M...
