Computers A garbled communication between 2 devices in a local area network (LAN) that results when both attempt to transmit data simultaneously; after colliding, each device waits for a period of time and retries; increased devices on a LAN increase the likelihood of collision
Obstetrics A mechanical obstruction to the birth of twins, such that the lay of one foetus impedes the engagement of the other; the most extreme collision is known as interlocking
Public health Road traffic accident/motor vehicle accident
Radiation physics The interaction between 2 particles—e.g., photons, atomic nuclei, electrons—during which energy, momentum, and charge may be altered

What is necessary to explain within variational electrodynamics is the mechanism to switch from the circular trajectory to a quasi-luminal head-on collisional trajectory at a discontinuous rate above threshold, a collapse caused by the bursting attractions between particles.

This hybrid LC-MS approach also features various dissociation methods, including Higher-energy Collisional Dissociation in the HCD collision cell (Figure 1) and Collision-Induced Dissociation in the linear ion trap.
At face value, it looks like Haumea's collisional family and the moons are one and the same--the product of some extraordinary event" early in the history of the solar system, comments Daniel Fabrycky of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass.

Recent advances are addressed under a wide variety of topics including, orbital properties; nomenclature; taxonomy; physical characteristics such as sizes, composition, colours, shapes and rotations; forma tion processes and collisional evolution; the largest objects; binaries; atmospheres; links with Jupiter-family comets, planetary satellites and other solar system populations; extrasolar dust disks; laboratory studies; and prospects for the future including stellar occultations, NASA's Pluto--Kuiper Belt mission New Horizons due to arrive at Pluto in 2015, and future surveys.
Holdren's knowledge and involvement in fusion goes back to the early 1970s, when he published a paper "Analytic Approximation to Collisional Distribution in Mirror Plasmas" while working in the magnetic fusion energy program at the Lawrence Livermore National Laboratory.
In support of this model, Collins (2002) points out that the mineralogy of many granulite facies complexes requires geothermal gradients between 20[degrees] and 50[degrees]C per km, which is much higher than gradients in collisional environments, but is consistent with those expected in backarc settings.
The continental collisional setting is analogous to gem provinces within the India-Asia collision zone, such as the Mogok Stone Tract in Burma (Myanmar).
