Evocation of motor representations during sentence comprehension was examined by training subjects to make a hand action in response to a visual cue while listening to a sentence. Sentences referred to manipulable objects that were either related or unrelated to the cued action. Related actions pertained either to the function of the object or to its volumetric properties (e.g., shape). The res...

Network Quality of Service (QoS) criteria of interest include conventional metrics such as throughput, delay, loss, and jitter, as well as new QoS criteria based on power utilization, reliability and security. In this paper we suggest a theoretical framework for the characterization and comparison of adaptive routing algorithms which use QoS as the criterion to select between different paths th...

We introduce a general contagionlike model for competing opinions that includes dynamic resistance to alternative opinions. We show that this model can describe candidate vote distributions, spatial vote correlations, and a slow approach to opinion consensus with sensible parameter values. These empirical properties of large group dynamics, previously understood using distinct models, may be di...
