A fundamental feature of the mind is its tendency to wander from the constraints of the perceptual moment towards internally generated thoughts and feelings. Recent interest in mind-wandering as a ...

Abstract: A 3-D bidirectional solution to the parabolic approximation of the wave equation is investigated by using a vector field representation. The backward propagating wave is integrated to the ...

It’s an underappreciated fact that the interior of every simplex Δ n \Delta^n is a real vector space in a natural way. For instance, here’s the 2-simplex with twelve of its 1-dimensional linear ...
