Transducer model produces facilitation from opposite-sign flanks
Small spots, lines and Gabor patterns can be easier to detect when they are superimposed upon similar spots, lines and Gabor patterns. Traditionally, such facilitation has been understood to be a consequence of nonlinear contrast transduction. Facilitation has also been reported to arise from non-overlapping patterns with opposite sign. We point out that this result does not preclude the tradit...
متن کاملOpposite cerebral dominance for reading and sign language.
We present a case of right hemispheric dominance for sign language but left hemispheric dominance for reading, in a left-handed deaf patient with epilepsy and left mesial temporal sclerosis. Atypical language laterality for ASL was determined by preoperative fMRI, and congruent with ASL modified WADA testing. We conclude that reading and sign language can have crossed dominance and preoperative...
متن کاملSmall RNAs of Opposite Sign… but Same Absolute Value
In ciliates, small RNAs have been shown to target foreign sequences for silencing via elimination from the somatic genome. Fang et al. now reveal a set of Piwi-interacting RNAs (piRNAs) in Oxytricha trifallax that likewise enable genomic self versus nonself discrimination, this time by specifying self sequences for genome retention.
متن کاملHEPHY–PUB 700/98 STPHY 30/98 MULTIPLICITY DEPENDENCE OF LIKE-SIGN AND OPPOSITE-SIGN CORRELATIONS IN p̄p REACTIONS
Discussions about Bose-Einstein correlations between decay products of coproduced W-bosons again raise the question about the behaviour of correlations if several strings are produced. This is studied by the multiplicity dependence of like-sign and opposite-sign correlations in p̄p reactions at √ s = 630 GeV. To be published in Proceedings of the 8 Internat. Workshop on Multiparticle Production ...
متن کاملInitial enlargement of the opposite pupil as a false localising sign in intraparenchymal frontal haemorrhage.
Ipsilateral third nerve palsy with early pupillary enlargement is an important sign of transtentorial herniation from a supratentorial mass lesion. A case of frontal, intraparenchymal haemorrhage is reported in which the first ocular manifestation of transtentorial herniation was enlargement of the contralateral pupil. The ipsilateral pupil dilated only after complete oculomotor palsy of the co...
