In the title compound, C13H8BrClOS, the thienyl ring is not coplanar with the benzene ring, their planes forming a dihedral angle of 13.2 (4)°. In the crystal, mol-ecules stack along the a axis, with the inter-planar separation between thienyl rings and between benzene rings being 3.925 (6) Å. The sample is an inversion twin.

In the title hydrated mol-ecular salt, C12H14N2S2 (2+)·2Cl(-)·2H2O, the dihedral angle between the benzene rings in the dication is 9.03 (17)° and the C-S-S-C torsion angle is 96.8 (2)°. The crystal packing can be described as alternating organic and anionic water layers lying parallel to (100), which are linked by N-H⋯Cl and N-H⋯O hydrogen bonds. O-H⋯Cl hydrogen bonds and aromatic π-π stacking...

In the title compound, C(15)H(16)N(2)O(5), the dihedral angle between 1,3-diazinane and benzene rings is only 4.27 (1)°. The essentially planar mol-ecular structure is characterized by a short intra-molecular C-H⋯O separation and by an exceptionally large bond angle of 138.25 (14)° at the bridging methine C atom. The meth-oxy groups deviate somewhat from the plane of the benzene ring, with C-C-...

In the title compound, C15H15NO4S, the dihedral angle between the benzene rings is 88.87 (1)°. In the crystal, adjacent mol-ecules form inversion dimers through pairs of strong N-H⋯O hydrogen bonds, generating R 2 (2)(8) loops. Two C-H⋯π inter-actions and an aromatic π-π inter-action [centroid-centroid separation = 3.8191 (1) Å] are also observed.

Small-angle neutron scattering experiments by interpenetrating networks of poly(carbonate-urethane) and polyvinyl pyridine reveal that there is some degree of microphase separation at all compositions, possibly, in some compositions, into a bicontinuous phase. The domain size is some undred angstroms in the samples with only one glass transition

In the title compound, C12H7N3O2S, the dihedral angle between the planes of the thia-zolo-pyridine ring system (r.m.s. deviation = 0.005 Å) and the benzene ring is 3.94 (6)°. The nitro group is rotated by 7.6 (2)° from its attached ring. In the crystal, extensive aromatic π-π stacking [shortest centroid-centroid separation = 3.5295 (9) Å] links the mol-ecules into (001) sheets.

In this contribution we study azimuthal angle decorrelation in inclusive dijet cross sections taking into account the next–to–leading (NLO) corrections to the BFKL kernel while keeping the jet vertices at leading order. We show how the angular decorrelation for jets with a wide relative separation in rapidity largely decreases when the NLO corrections are included.

In the title compound, C(15)H(11)BrO(3), the dihedral angle between the naphtho-furan ring system (r.m.s. deviation = 0.022 Å) and the side chain is 4.50 (2)°. In the crystal, short Br⋯Br [3.4435 (7) Å] contacts propagating along [010] in a zigzag manner and weak π-π inter-actions [shortest centroid-centroid separation = 3.573 (2) Å] directedalong [100] are observed.

In the title compound, C(14)H(12)N(2)O(4)S, the dihedral angle between the two aromatic rings is 35.65 (12)°. The crystal packing is stabilized by weak C-H⋯O hydrogen bonds and aromatic π-π ring stacking inter-actions [minimum ring centroid separation = 3.697 (3) Å].

A new crossing detector is presented which also permits orientation estimation of the underlying structures. The method relies on well established tools such as the structure tensor, the double angle mapping and descriptors for second order variations. The performance of our joint crossing detector and multi-orientation estimator is relatively independent of the angular separation of the underl...
