The standard account is that the original beam is a superposition of electrons with their magnetic moments aligned with the field, and of electrons with magnetic moments antiparallel to the field.
Except for oxygen, all known bi-atomic molecules, such as [N.sub.2], [Br.sub.2], [Cl.sub.2], [H.sub.2], and [He.sub.2], have their electrons spin in an antiparallel manner allowing the electrons from the two atoms to share a single orbital and, consequently form a covalent bond [14].
The latter is composed of antiparallel homodimers that crosslink the thin actin filaments of neighboring sarcomeres (Yu et al., 2003).
A "jelly-roll" fold of a six stranded antiparallel [beta]-sheet packing on the outside of a nine-stranded mostly antiparallel [beta]-sheet curved around an active site cleft.
The structure of one of these, an antiparallel G-quadruplex structure composed of only two tetrads, was also confirmed using NMR [4].
In previous studies, anionic PL vesicles could accelerate adoption of antiparallel [beta]-sheet structure with the formation of large fibril aggregation which is the toxicity of A[beta] toward PL [8, 9].
To deal with the power transfer degradation due to frequency splitting, the schemes of nonidentical transmitting and receiving coils, antiparallel resonant loop transmitter (TX), and mixed magnetic and electric coupling have been proposed to prevent frequency splitting via suppressing the coupling strength in references [4-6].
The eigensolutions of the supersymmetric conformal algebra thus have a 2 x 2 Pauli matrix representation, where the upper-left component corresponds to mesonic q[bar.q] colorsinglet bound states; the two off-diagonal eigensolutions [[psi].sup.[+ or -]] correspond to a pair of Fock components of baryonic quark-diquark states with equal weight, where the quark spin is parallel or antiparallel to the baryon spin, respectively.
CLPs are stochastically ordered structures oriented antiparallel to the direction of the incident laser beam.
This inverter is formed using five switches with antiparallel diodes, where S11 to S14 are arranged as the traditional CHB inverter, while, however, S15 is added to increase the output voltage levels by selecting the appropriate voltage source.
The coexistence of [alpha]-form crystals (i.e., (200) and (002, 220) reflections at 2[theta] = 20.3[degrees] and 23.3[degrees], respectively) and [gamma]-form crystals (i.e., (001, 200) reflection at 2[theta] = 21.3[degrees]) of PA6 are consistent with previously reports [22, 25, 26], Generally, the [alpha] crystalline phase is thermodynamically stable for PA6 and consists of sheets of hydrogen-bonded chains formed between antiparallel chains, while the [gamma] crystalline phase is meta-stable and consists of random hydrogen bonding between parallel chains [25-27].
