antiparallel

[¦an·tē′par·ə‚lel]
(genetics)
The opposite orientation of the two complementary strands or deoxyribonucleic acid, 5′ to 3′ and 3′ to 5′.
(mathematics)
Property of two nonzero vectors in a vector space over the real numbers such that one vector equals the product of the other vector and a negative number.
(physics)
Property of two displacements or other vectors which lie along parallel lines but point in opposite directions.

10-stranded antiparallel (3- barrel and an N-terminal helix-turn-helix
1 electron in the N = 1 shell, and the second electron in any of the N>1 shells), helium can exist either as a singlet (parahelium--spins remaining antiparallel to one another) or as a triplet (orthohelium --spins assume a parallel configuration).
Similarly coupling to magnetic field happens between the resonator and backside conductive plane, which manifests itself, as antiparallel surface currents as shown in the Fig.

It should be noted that some of the higher-energy binding poses obtained for PCB sulfates exhibited an antiparallel orientation with the sulfate group pointing towards the central Ser117.
As can be seen in Figure 3(a), for one-layer MMA, charges accumulate mainly at the two ends of the square loop, indicating a response to the electric field component, while the currents are antiparallel on the loop and ground, which induces a strong response to the magnetic field component.
FAD domain consists five stranded parallel beta sheets (7-10, 31-35, 119-124, 155-158 and 322-324), three stranded antiparallel beta sheets (126-129, 134-138 and 149-152) and four alpha helices (14-26, 50-78, 92-116 and 335-349).
