The present investigation shows that the aftereffect of induced rotation is observable when there is a large separation of inducing and static areas; it also has a substantial monocular component. These points are consistent with the possible involvement of lateral inhibition in movement detectors, (a) A recent study shows the importance of a peripheral inducing stimulus, and therefore presumably peripheral movement detectors; other psychophysical evidence shows that such detectors have large receptive fields and inhibitory surrounds. (b) Other effects probably involving lateral inhibition in movement detectors have a large monocular component.

And Control

Integrated optical components (mostly single-mode fibers and couplers) can be used to achieve several functions that are needed in interferometry: coherent beam transportation and recombination, pathlength modulation and control for fringe tracking and double Fourier interferometry, spatial filtering of the wavefront and interferogram calibration. Their potential is assessed and the main problems encountered in their implementation are discussed: dispersion, polarization behavior, and especially starlight injection.

AbstractThe inclusive hadroproduction of two heavy quarks, featuring a large separation in rapidity, is proposed as a novel probe channel of the Balitsky–Fadin–Kuraev–Lipatov (BFKL) approach. In a theoretical setup which includes full resummation of leading logarithms in the center-of-mass energy and partial resummation of the next-to-leading ones, predictions for the cross section and azimuthal coefficients are presented for kinematic configurations typical of current and possible future experimental analyses at the LHC.
