A twisted pair of photonic crystals integrated with MEMS can dynamically control the handedness of light on a chip.
They are not exactly extra-terrestrials, but encoders, with their ability to mysteriously translate disparate TV signals, of competing compression levels, so that they can be passed along the workflow ...
Abstract: Modern transient electromagnetic (TEM) surveys, either ground-based or airborne, may yield thousands of line kilometers of data. Parts of these data, especially in areas with dense ...
Abstract: As the helical gear is widely used as transmission part in the planetary gear train system, a six-degree-of-freedom bending-torsion-axis coupling dynamic model is established for the helical ...
