The AII amacrine cell (AII) is a key information hub in the retina, allowing rod-driven signals to piggyback onto cone-dominated circuitry. In this issue, Balakrishnan et al. (2015) use capacitance recordings to unravel mechanisms of inhibitory synaptic transmission by AIIs.

We propose a piggybacking scheme for network coding where strong source inputs piggyback the weaker ones, a scheme necessary and sufficient to achieve the cut-set upper bound at high/low-snr regime, a new asymptotically optimal operational regime for the multihop Amplify and Forward (AF) networks.

Expansive playa-lake systems situated in high-altitude piggyback basins are important and conspicuous components of both modern and ancient cordilleran orogenic systems. Extant playa lakes provide vital habitat for numerous endemic species, whereas sediments from these deposystems may record signals of climate change or develop natural resources over geological time. Laguna de los Pozuelos (Nor...

PURPOSE To evaluate how soft lens power affects rigid gas-permeable (RGP) lens power and visual acuity (VA) in piggyback fittings for keratoconus. METHODS Sixteen keratoconus subjects (30 eyes) were included in the study. Piggyback contact lens fittings combining Senofilcon-A soft lenses of -6.00, -3.00, +3.00 and +6.00 D with Rose K2 RGP contact lenses were performed. Corneal topography was ...

We describe an extension of the Spin model checker that allows us to take advantage of the increasing number of cpu-cores available on standard desktop systems. Our main target is to speed up the verification process for safety properties, the mode used most frequently, but we also describe a small modification of the parallel search algorithm, called the piggyback algorithm, that is remarkably...

THIS STUDY DESCRIBES A CLINICAL OBSERVATION OF SUCCESSFUL IMPLEMENTATION OF A NEW SURGICAL MANEUVER: formation of a cross tunnel under the mouths of the major hepatic veins during removal of a tumor thrombus of the inferior vena cava. This surgical technique helps avoid the usage of   "piggyback" mobilization of the liver and the complications associated with it. However, for objective evaluati...
