TL;DR: SSG is superior to commercial voice synthesizers because it yields speech stimuli of a highly natural quality due to the contribution of the man-originating glottal excitation, making SSG suitable for cognitive experiments using speech sounds as stimuli.

TL;DR: The auditory cortex activation to a visual change occurred later in the visual than in the audiovisual experiment, suggesting that interaction between modalities accelerates the detection of visual change in speech.

TL;DR: In this paper, an analysis of a sample of 458 acquisitions demonstrates that although higher premia are paid for R&D-related assets, the premia do not cause negative abnormal returns.
Abstract: Several studies argue that paying high acquisition premia is value destroying for acquirer shareholders. There are studies that have even used the size of premium as a measure of low-quality decision making. This paper departs from the earlier research and shows that acquisition premia may be justified when target firms' resources are difficult for the market to value. An analysis of a sample of 458 acquisitions demonstrates that although higher premia are paid for R&D-related assets, the premia do not cause negative abnormal returns. Abnormal returns are more strongly affected by the overall target price levels independent of premia. Copyright © 2007 John Wiley & Sons, Ltd.

TL;DR: The results for several metals and semiconductors show that the GGA systematically improves the predictive power of positron lifetime calculations over those based on the LDA.
Abstract: First-principles calculations of positron-annihilation characteristics in solids are usually based on the local-density approximation (LDA) for positron-electron correlation. The LDA systematically overestimates the annihilation rate. As a remedy we introduce a generalized gradient approximation (GGA). Our results for several metals and semiconductors show that the GGA systematically improves the predictive power of positron lifetime calculations over those based on the LDA. We compare also the resulting positron energy levels in solids with data from slow-positron experiments.

TL;DR: The detection of magnetic mu rhythm in four subjects using a large-area seven-channel first-order superconducting quantum interference device gradiometer suggests that the mu rhythm is generated mainly at the primary somatosensory hand projection area.
