In optics, an ARROW (anti-resonant reflecting optical waveguide) is a type of waveguide that uses the principle of thin-film interference to guide light with low loss. It is formed from an anti-resonant Fabry–Pérot reflector. The optical mode is leaky, but relatively low-loss propagation can be achieved by making the Fabry–Pérot reflector ...
Image destriping is the process of removing stripes or streaks from images and videos without disrupting the original image/video. These artifacts plague a range of fields in scientific imaging including atomic force microscopy , [ 2 ] light sheet fluorescence microscopy , [ 3 ] and planetary satellite imaging .
As with static strip photography, videos can be produced both in "tableau" format (conventional almost square aspect ratio), or in "strip" format (very wide), and in fact can have exactly the same dimensions as the input video if input frames = input x-resolution (so the (,,) array is square in the (,) dimensions); in this case if input and ...

Traditional target arrow (top) and replica medieval arrow (bottom) Modern arrow with plastic fletchings and nock An arrow is a fin-stabilized projectile launched by a bow.A typical arrow usually consists of a long, stiff, straight shaft with a weighty (and usually sharp and pointed) arrowhead attached to the front end, multiple fin-like stabilizers called fletchings mounted near the rear, and ...
An arrow is a graphical symbol, such as ← or →, or a pictogram, used to point or indicate direction. In its simplest form, an arrow is a triangle , chevron , or concave kite , usually affixed to a line segment or rectangle , [ 1 ] and in more complex forms a representation of an actual arrow (e.g. U+27B5).
Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [1] It was first developed by Sir Robert Robinson . In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism .
