We describe some simulations that compare cultural transmission between and within generations (inter-generational vs intra-generational transmission) in populations of embodied agents controlled by neural networks. Our results suggest that intra-generational transmission has the role of adding variability to the evolutionary process and that this function seems particularly useful when the pop...

BACKGROUND Antisocial behavior and substance dependence disorders exact a heavy financial and human cost on society. A better understanding of the mechanisms of familial transmission for these "externalizing" disorders is necessary to better understand their etiology and to help develop intervention strategies. OBJECTIVES To determine the extent to which the family transmission of externalizi...

This study develops a form of digital baseband Intra-Body communication for wideband transmission. A simplified circuit model of signal and noise is constructed to analyze the contribution of the high pass filter function of the electrostatic coupling Intra-Body communication system to wideband digital transmission in electrostatic coupling Intra-Body communication. A unit step function is pres...

The authors describe the application of multivariate analysis to the problem of estimating intra-family correlations and testing them for statistical significance. This is illustrated by a re-analysis of survey data collected by Miall and Oldham (Clin Sci 1958;17:459-87) on the familial aggregation of blood pressure. The multivariate analysis provides collective tests of significance for parent...

We report an autopsy case of a 35-yr-old man with familial visceral myopathy, a cause of primary intestinal pseudo-obstruction. The patient died from complications of familial visceral myopathy, sepsis, and generalized signet-ring cell carcinomatosis. The patient had massive distension of the large and small intestines, a dilated thickened esophagus, and fibroneoplastic adhesions between intra-...

BACKGROUND There is increasing evidence that substance use disorders are familial and that genetic factors explain a substantial degree of their familial aggregation. To perform a controlled family study of probands with several different predominant drugs of abuse, including opioids, cocaine, cannabis, and/or alcohol. METHODS The subjects for the present study included 231 probands with depe...
