Low-voltage cascode current mirrors are reviewed with respect to the design limitations imposed if all transistors in the mirror are required to operate in the saturation region. It is found that both a lower limit and an upper limit exist for the cascode transistor bias voltage. Further, the use of a signal dependent cascode bias voltage is discussed and a selfbiased cascode configuration is p...

Mirror neurons and canonical neurons are two classes of visuomotor neurons that are activated by different visual stimuli (Rizzolatti and Kalaska, 2012). Mirror neurons respond to a biological effector interacting with an object (Gallese et al., 1996), suggesting their role in action recognition, while canonical neurons respond to the presentation of a graspable object (Murata et al., 1997), an...

This paper discusses the relevance of the discovery of mirror neurons in monkeys and of the mirror neuron system in humans to a neuroscientific account of primates' social cognition and its evolution. It is proposed that mirror neurons and the functional mechanism they underpin, embodied simulation, can ground within a unitary neurophysiological explanatory framework important aspects of human ...

The discovery of mirror neurons (e.g., Gallese et al., 1996) has reignited interest in theories that postulate a tight functional link between perception and action. According to these theories, perception and action share a common representational code, with actions coded in terms of the distal perceptual effects that they produce (Prinz, 1997). Accordingly, action representations should be ac...

In the Omega EP laser, the pulse must be stretched in time, amplified, and subsequently compressed in a grating compressor in order to obtain high peak power. A model was used to characterize the temporally resolved near-field and far-field beam distributions for several different compressor configurations that included grating alignment errors and grating surface figure errors. The spatio-temp...

We compute the Coifman-Meyer-Wickerhauser measure μ for certain families of quadrature mirror filters (QMFs), and we establish that for a subclass of QMFs, μ contains a fractal scale.

The mirror foot is a rare congenital foot anomaly which is often associated with 6- to 8-toed polydactyly. Postaxial polydactyly is the most common form of this anomaly, while central polydactyly is seen infrequently. We report on 2 cases of the central mirror-foot anomaly. Calcaneus duplication and fibular hypoplasia were present in 1 case. We treated both patients by resecting the middle foot...
