Chaotic dynamics from interspike intervals.
Considering two different mathematical models describing chaotic spiking phenomena, namely, an integrate-and-fire and a threshold-crossing model, we discuss the problem of extracting dynamics from interspike intervals (ISIs) and show that the possibilities of computing the largest Lyapunov exponent (LE) from point processes differ between the two models. We also consider the problem of estimati...
متن کاملApplication of qualitative research in management (why, when and how)
Application of qualitative research in management (why, when and how) Qualitative research has been increasingly used in all sciences. In this paper we will discuss about the applications of qualitative research methods in management sciences. The differences between quantitative and qualitative researches will be clarified and the statistical methods which are suitable for such researches will...
متن کاملSystem Reconstruction and Analysis Using Interspike Intervals
Statistical measures of determinism for spikes train are described and analyzed. The analysis is focused on two dynamical invariants: nonlinear forecastability and correlation dimension. Two simple, generic, biologically motivated methods for generating spikes from the system are surveyed: an integrate-and-fire model (IF) and a threshold-crossing method (TC). The effect on the statistical measu...

The gene miR-17-92 encodes six different microRNAs, with one of these acting as an internal brake that opposes the oncogenic activity of the others in some cancer contexts.
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
