Is it better to move first, or second– to innovate, or to imitate? We look at this in a context with both asymmetric information and payoff externalities. Suppose two players, one with superior information about market quality, consider entering one of two new markets immediately or waiting until the last possible date. We show that the more accurate the informed player’s information, the more ...

The detection of human and spoofed (synthetic/converted) speech has started to receive more attention. In this study, relative phase information extracted from a Fourier spectrum is used to detect human and spoofed speech. Because original/natural phase information is almost entirely lost in spoofed speech using current synthesis/conversion techniques, a modified group delay based feature, the ...

background:the different duration of delay to first contact with a psychiatrist in depressive disordered patients has been observed in western and non western cultures. this study aimed to examine the duration and predictive factors of delay in contact with a psychiatrist in depressive patients in isfahan city of iran. methods:in this cross sectional study 156 depressive patients were recruited...

conclusions penetrating trauma from wooden fragments provides a diagnostic challenge. a stubborn discharge from a wound must always raise the suspicion of retained fragment. early and appropriate surgical exploration is imperative. introduction in contrast with victims of major trauma, patients who suffer minor injuries receive little specialist input. in most cases, this causes no difficulty, ...

In general, information about the environment (for instance a target) is not instantaneously available for the nervous system. A minimal delay for visual information to affect the movement of the hand is about 110 ms. However, if the movement of a target is predictable, humans can pursue it with zero delay. To make this prediction, information about the speed of the target is necessary. Our res...

We address the problem of formalizing an information diffusion process on a social network as a generative model in the machine learning framework so that we can learn model parameters from the observation. Time delay plays an important role in formulating the likelihood function as well as for the analyses of information diffusion. We identified that there are two different types of time delay...

In this work, the uplink of a CDMA system with two user classes is considered. One of the classes consists of delay intolerant users requiring support for a constant information bit rate R, while the other consists of delay tolerant users needing support for an information bit rate of at least Rm. It is assumed that when not transmitting information, both classes maintain synchronization contac...
