(rail transport) An at-grade junction between two crossing railroad tracks.

(rail transport) An at-grade junction between two crossing railroad tracks.

(railways) A location where two railroad tracks cross, without switches, as where different roads intersect.

(physics) A device in which the detection of radiation takes place at the depletion junction of a reverse-biased semiconductor junction.

(genetics) A non-linear strand of DNA where certain cruciform binding proteins can compete for binding.

(physics) a weak insulating barrier between two superconductors, used as an ultrafast switch

(physics) A semiconductor rectifying device in which the barrier between the two regions of opposite conductivity (n-type and p-type) type produces the rectification. All solar cells are junction diodes.

(physics) A transistor in which the emitter and collector barriers are formed by p-n junctions between semiconductor regions of opposite conductivity type.

A small city in Union County, Arkansas, United States. / A census-designated place in Trinity County, California, United States.

A junction designed to prevent congestion and gridlock. Vehicles may only enter the box-shaped area (usually marked with crossing diagonal lines) if their exit from the junction is clear, or in some cases if they intend to make a turn.
