In the title salt, C6H9ClN3 (+)·C6H3O4S(-), the cations and anions are linked via O-H⋯O and N-H⋯O hydrogen bonds, forming R 6 (6)(37) ring motifs that are inter-connected with each other, producing sheets. Separate parallel inversion-related sheets are linked through N-H⋯N and π-π stacking inter-actions [centroid-centroid distance = 3.5414 (13) Å], forming double layers parallel to (101). Weak ...

The asymmetric unit of the title salt, C8H14N2 (2+)·2NO3 (-), contains two independent dications and four independent nitrate anions. The crystal structure consists of discrete nitrate ions, three of which stack in layers parallel to (001) at z = 0 and 0.5. These layers are connected via m-xylylenediaminium dications. The fourth anion is sandwiched by the two independent organic cations in the ...

In this paper, both the architecture and learning procedure underlying the parallel layer perceptron is presented. This topology, di1erent to the previous ones, uses parallel layers of perceptrons to map nonlinear input–output relationships. Comparisons between the parallel layer perceptron, multi-layer perceptron and ANFIS are included and show the e1ectiveness of the proposed topology. c © 20...

The title compounds, C16H15N5OS, (I), and C12H12FN5OS, (II), are [(di-amino-pyrimidine)-sulfan-yl]acetamide derivatives. In (I), the pyrimidine ring is inclined to the naphthalene ring system by 55.5 (1)°, while in (II), the pyrimidine ring is inclined to the benzene ring by 58.93 (8)°. In (II), there is an intra-molecular N-H⋯N hydrogen bond and a short C-H⋯O contact. In the crystals of (I) an...

In the crystal of the title mol-ecular salt, C6H7BrN(+)·C7H7O3S(-), the anions and cations are linked via N-H⋯O hydrogen bonds forming layers, enclosing R 2 (2)(4) ring motifs, lying parallel to (001). Within the layers there are short O⋯O contacts of 2.843 (2) Å.

The title butterfly-shaped mol-ecule, C(11)H(6)N(2)O(2), is folded slightly along the O=C⋯C=O line, the dihedral angle between the two parts being 6.42 (3)°. In the crystal, adjacent mol-ecules are linked through C-H⋯O hydrogen bonds into infinite layers parallel to the ac plane. The layers are further connected into a three-dimensional netweork via π-π inter-actions formed between pairs of ant...

• We identify a novel strategy to parallelize composite and filter across individual depth fragments, and describe an implementation on a modern GPU. We demonstrate that this technique is applicable to several areas with four examples: a particle system, a volume renderer, a polygon rasterizer and an interactive Reyes pipeline. • We compare the performance of the proposed fragment-parallel stra...

Self-assembly of ABC star triblock copolymers confined in cylindrical nanopores is studied using real-space self-consistent mean-field theory. Specifically, the investigation focuses on the confined self-assembly of a triblock copolymer which forms hierarchical lamellae in the bulk. Generically, the hierarchical lamellae can be parallel or perpendicular to the pore surfaces. Concentric rings of...

In the title compound, NH(4) (+)·(C(2)H(5)O)(2)PS(2) (-), the ammonium cation is connected by four charge-assisted N-H⋯S hydrogen bonds to four tetra-hedral O,O'-diethyl dithio-phosphate anions, forming layers parallel to (100). The polar and non-polar constituents of the layers are stacked alternately along [100]. Inter-lacing of the external ethyl groups through van der Waals inter-actions co...

The crystal structure of the title compound, C(8)H(12)N(+)·Cl(-)·H(2)O, consists of hydro-phobic layers of dimethyl-anilinium cations parallel to the bc plane alternated by hydro-philic layers of chloride anions and water mol-ecules. The layers are linked by N-H⋯O and N-H⋯Cl hydrogen bonds involving the ammonium groups of the cations. The cohesion of the ionic structure is further stabilized by...
