The study revealed a new mechanism whereby a gradient of retinoic acid (RA), a known morphogen, organizes the zebrafish vagus motor topographic map by coordinating chemoattractant signaling between ...

Learn how to calculate the equation of a line from a graph, work out the gradient from an equation, and visualise intercepts with this step-by step guide.

For stationary harmonic maps between Riemannian manifolds, we provide a necessary and sufficient condition for the uniform interior and boundary gradient estimates in terms of the total energy of maps ...

We provide an explicit gradient formula for linear chance constraints under a (possibly singular) multivariate Gaussian distribution. This formula allows one to reduce the calculus of gradients to the ...

A quantum gravity gradient sensor developed by researchers in the UK has been used outdoors to locate a small underground structure. Using a pair of vertically oriented atom interferometers that are ...
