This way of writing it makes the grouping part of the computation more explicit. And thegroupbyfunction is more versatile, so if you only want to learn one thing, you might prefer this version. Theunstackat the end is only needed if you want a wide table (with time down the rows and ...
He described an ongoing 4-year research project to determine the probability of eye injury from handheld lasers at a distance; results may be available in 2020. Finally, he discussed Swedish law which includes a requirement for a license to own a handheld laser over 1 milliwatt. The final ...
(a) The parametric down-conversion based photon pair source with quarter-waveplates (QWP), half-waveplates (HWP) and a polarisation beamsplitter cube (PBS) used as a polariser, to control the initial state before input into the chip. Down conversion in the nonlinear bismuth borate (BiBO) ...
