This paper examines the effect of “stencil width” on surface ocean geostrophic velocity and vorticity estimated from differentiating gridded satellite altimeter sea surface height products. In oceanographic applications, the value of the first derivative at a central grid point is generally obtained by differencing the sea surface heights at adjacent...
The Brain Research through Advanced Innovative Neurotechnologies (BRAIN) initiative seeks to understand how ensembles of neurons create neural networks. The initiative has spurred the pursuit of developing novel experimental tools for investigating how individual neurons propagate electrical signals (action potentials) to produce ensemble behavior. Classical techniques to measure the internal...
