We investigate the statistics of the time taken for a system driven by recruitment to reach fixation. Our model describes a series of experiments where a population is confronted with two identical options, resulting in the system fixating on one of the options. For a specific population size, we show that the time distribution behaves like an inverse Gaussian with an exponential decay. Varying...

Thrombolysis for stroke is being used in some developing countries. This study was designed to evaluate the problems of thrombolysis therapy in Iran. During January-July 2008, all patients with ischemic stroke admitted to Ghaem Hospital, Mashhad, northeast Iran, were enrolled in a prospective observational study. Ghaem Hospital is a tertiary care hospital that includes infrastructure for thromb...

The short-time Fourier transform of a discrete-time signal, which is the Fourier transform of a “windowed” version of the signal, is interpreted as a sliding-window spectrum. This sliding-window spectrum is a function of two variables: a discrete time index, which represents the position of the window, and a continuous frequency variable. It is shown that the signal can be reconstructed from th...

finite affine groups are given by groups of translations and di-lations on finite cyclic groups. for cyclic groups of prime orderwe develop a time-scale (wavelet) analysis and show that for alarge class of non-zero window signals/vectors, the generatedfull cyclic wavelet system constitutes a frame whose canonicaldual is a cyclic wavelet frame.

Modern microprocessors schedule instructions dynamically in order to exploit instruction level parallelism. It is necessary to increase instruction window size for improving instruction scheduling capability. However, it is di cult to increase the size without any serious impact on processor performance, since the instruction window is one of the dominant deciding processor cycle time. The reas...
