anti-parallel

Space physicists have made a distinction between reconnection when both fields are in opposite directions, or anti-parallel, and component reconnection, when the IMF is neither parallel nor anti-parallel to the terrestrial magnetic field.

"These observations support the idea that both anti-parallel and component reconnection occur at the dayside magnetopause under the same IMF conditions and that both phenomena might be the local signatures of a global reconnection picture", says Professor Malcolm Dunlop from the Rutherford Appleton Laboratory, Didcot, UK.

For the first time, four spacecraft flying in constellation the ESA Cluster mission, have provided unambiguous evidence of anti-parallel reconnection at high latitude on the dayside magnetopause, occurring quasi-simultaneously with a period of low-latitude component reconnection detected by the Sino-European Double Star TC-1 satellite.

The distinction is important since component and anti-parallel reconnection have different onset characteristics and lead to different duration of the fissures in the magnetic shield.

She measured the unit cell dimensions and classified the space group as C2, but did not realize, as Crick did, its implication that the two sides of the sugar-phosphate backbone must run in opposite directions (anti-parallel).

So it was possible with this system to get a system in which it was possible to change from parallel to anti-parallel polarizers.

And based on this expectation then we expected that there should be a difference for the resistance between the parallel and the anti-parallel magnetization alignment in such double-layered structures.

FliI seems to have several short alpha-helices, an anti-parallel beta-sheet, and maybe a little beta-strand.

They turned out to be the transition to phase A, where the individual members of the boson pairs have parallel spins, and to the phase B, in which they have both parallel and anti-parallel spins.

He found that for certain crystals adjacent elementary magnets could align themselves anti-parallel and not parallel as in ferro-magnetic materials.
