Repetition of the same stimulus leads to a reduction in neural activity known as repetition suppression (RS). In functional magnetic resonance imaging (fMRI), RS is found for multiple object categories. One proposal is that RS reflects locally based "within-region" changes, such as neural fatigue. Thus, if a given region shows RS across changes in stimulus size or view, then it is inferred to h...

Abstract We construct moduli spaces of complex affine and dilation surfaces. Using ideas Veech [W. A. Veech, Flat surfaces, Amer. J. Math. 115 1993, 3, 589–689], we show that the space

OBJECTIVES Bilobectomy is considered to be a risky procedure due to space mismatch between the pleural space and the remnant lung. The objective of this study was to evaluate if postoperative complications related or not to size mismatch are more frequent after bilobectomy compared with right lobectomy cases. METHODS Retrospective case-control study on a series of matched non-small-cell lung ...

In this paper we explicitly prove the invariance of the time-dependent string gravity Lagrangian with up to four derivatives under the global O(d, d) symmetry.

In the hippocampus, interneurons provide synaptic inhibition via the transmitter GABA, which can activate GABA(A) and GABA(B) receptors (GABA(A)Rs and GABA(B)Rs). Generally, however, GABA released by a single interneuron activates only GABA(A)Rs on its targets, despite the abundance of GABA(B)RS. Here, I show that during hippocampal rhythmic activity, simultaneous release of GABA from several i...

The recombination signals (RS) that guide V(D)J recombination are phylogenetically conserved but retain a surprising degree of sequence variability, especially in the nonamer and spacer. To characterize RS variability, we computed the position-wise information, a measure correlated with sequence conservation, for each nucleotide position in an RS alignment and demonstrate that most position-wis...
