This paper analyzes the dynamic stability of moral codes in a two population trust game. Guided by a moral code, members of one population, the Trustors, are willing to punish members of the other population, the Trustees, who defect. Under replicator dynamics, adherence to the moral code has unstable oscillations around an interior Nash Equilibrium (NE), but under smoothed best response dynami...

We studied the detection of chromoluminance patterns in the presence of chromoluminance pedestals. We examined how thresholds depend on the color directions of the target and the pedestal. Both targets and pedestals were spatial Gabor patterns (horizontal, 1 cpd) .The patterns were spatially modulated in color, luminance or both. Equidiscrimination contours describe contrast thresholds for targ...

This paper applies quantal response equilibrium (QRE) models (McKelvey and Palfrey, Games and Economic Behavior 10 (1995), 6-38) to a wide class of symmetric coordination games in which each player's best response is determined by an order statistic of all players' decisions, as in the classic experiments of Van Huyck, Battalio, and Beil (American Economic Review 80 (1990), 234-248; Quarterly J...

This paper studies properties of equilibrium selection based on quantal response equilibrium (QRE) models (McKelvey and Palfrey, Games and Economic Behavior 10 (1995), 6-38). In a QRE, the chances of playing sub-optimal strategies by mistakes are proportional to expected payo ̄ s, and QRE produces a distinct prediction from other noise-based re§ nements. A selection based on QRE coincides with r...

We analyze data from the second-price maximum-value auction experiment reported in Ivanov, Levin and Niederle (2010) in order to investigate the extent to which the winner’s curse can be explained by quantal response, in combination with diffferent assumptions about equilibrium (QRE) or nonequilibrium beliefs (QCH or QCE). We find a close correspondence between the theoretical predictions of th...

This research is on improving the efficiency of our previous work for removing semantically equivalent expressions in program search results.

    Background: Intelligibility refers to understandability of speech; and lack of it can negatively affect children’s overall communication effectiveness. Children with repaired cleft lip and/or cleft palate (CL/P) may experience poor speech intelligibility. This study aimed at evaluating speech intelligibility in children with repaired CL/P who had not been referred to sp...

In this paper an estimator for speech enhancement based on Laplacian Mixture Model has been proposed. The proposed method, estimates the complex DFT coefficients of clean speech from noisy speech using the MMSE  estimator, when the clean speech DFT coefficients are supposed mixture of Laplacians and the DFT coefficients of  noise are assumed zero-mean Gaussian distribution. Furthermore, the MMS...
