We demonstrated a 400Gb/s Ethernet end-to-end circuit, inclusive of 400GbE client card with CPF8 interface and dual-carrier 16QAM line-side, on a production 100G core network segment between New York City and Washington DC. During the field trial, we demonstrated the feasibility of SDN-enabled creation, deletion, and re-routing of the 400G service.

In the title compound, [Zn(C(4)H(5)O(2))Cl(C(6)H(6)N(4)S(2))]·H(2)O, the Zn(II) cation is coordinated by a bidentate diamino-bithia-zole (DABT) ligand, a but-2-enoate anion and a Cl(-) anion in a distorted tetra-hedral geometry. Within the DABT ligand, the two thia-zole rings are twisted to each other at a dihedral angle of 4.38 (10)°. An intra-molecular N-H⋯O inter-action occurs. The centroid-centroid distance of 3.6650 (17) Å and partially overlapped arrangement between nearly parallel thia-zole rings of adjacent complexes indicate the existence of π-π stacking in the crystal structure. Extensive O-H⋯Cl, O-H⋯O, N-H⋯Cl and N-H⋯O hydrogen bonding helps to stabilize the crystal structure.

In the crystal structure of the title compound, [Pb(2)(C(4)H(5)NO(4))(2)(C(6)H(6)N(4)S(2))(2)]·4H(2)O, the dinuclear Pb(II) complex mol-ecule is centrosymmetric. The Pb atom is chelated by a tridentate imino-diacetate anion (IDA) and a diamino-bithia-zole (DABT) ligand, while a carboxyl-ate O atom from an adjacent IDA anion further bridges the Pb atom with a longer Pb-O bond [2.892 (3) Å]. The lone-pair electrons of the Pb atom occupy an axial site in the Ψ-penta-gonal-bipyramidal coordination polyhedron. The IDA anion displays a facial configuration: its chelating five-membered rings assume an envelope configuration. Within the DABT ligand, the two thia-zole rings are twisted relative to each other, making a dihedral angle of 9.51 (17)°. Extensive N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonding helps to stabilize the crystal structure.

In the title compound, [Zn(C4H5O2)Cl(C6H6N4S2)]·H2O, the ZnII cation is coordinated by a bidentate diaminobithiazole (DABT) ligand, a but-2-enoate anion and a Cl− anion in a distorted tetrahedral geometry. Within the DABT ligand, the two thiazole rings are twisted to each other at a dihedral angle of 4.38 (10)°. An intramolecular N—H...O interaction occurs. The centroid–centroid distance of 3.6650 (17) Å and partially overlapped arrangement between nearly parallel thiazole rings of adjacent complexes indicate the existence of π–π stacking in the crystal structure. Extensive O—H...Cl, O—H...O, N—H...Cl and N—H...O hydrogen bonding helps to stabilize the crystal structure.

In the crystal structure of the title compound, [Pb2(C4H5NO4)2(C6H6N4S2)2]·4H2O, the dinuclear PbII complex molecule is centrosymmetric. The Pb atom is chelated by a tridentate iminodiacetate anion (IDA) and a diaminobithiazole (DABT) ligand, while a carboxylate O atom from an adjacent IDA anion further bridges the Pb atom with a longer Pb—O bond [2.892 (3) Å]. The lone-pair electrons of the Pb atom occupy an axial site in the Ψ-pentagonal-bipyramidal coordination polyhedron. The IDA anion displays a facial configuration: its chelating five-membered rings assume an envelope configuration. Within the DABT ligand, the two thiazole rings are twisted relative to each other, making a dihedral angle of 9.51 (17)°.

In the title complex, [Zn(C(17)H(11)N(6)O)Cl(C(3)H(7)NO)], the Zn(II) atom has a distorted square-pyramidal coordination formed by one Cl, two O and two N atoms. In the crystal structure, intermolecular N-H center dot center dot center dot Cl hydrogen bonds link molecules into centrosymmetric dimers, which are further assembled by pi-pi interactions [centroid-centroid distances = 3.809 (3) and 3.834 (3) angstrom] into layers parallel to the ab plane. The crystal packing exhibits also weak intermolecular C-H center dot center dot center dot Cl interactions.

In the title salt, C6H8N4S22+center dot 2C(7)H(4)NO(4)(-), the diprotonated diaminobithiazole dication is located on an inversion center. The carboxylate group of the anion is twisted with respect to the benzene ring, with a dihedral angle of 13.6 (4)degrees. N-H center dot center dot center dot O hydrogen bonds involving the amino and ammonium groups of the dication and the carboxylate functionality of the anion generate supramolecular chains in the crystal.

In the title compound, [Cr(C(6)H(7)N(4)S(2))(C(6)H(4)O(7))(H(2)O)]·2H(2)O, the Cr(III) atom is in a distorted octa-hedral environment, coordinated by one water mol-ecule, two N atoms from a protonated diamino-bithia-zole ligand and three O atoms from a citrate(4-) anion. The complex is zwitterionic, with the H atom from the uncoordinated carboxyl-ate group of the citrate anion transferred to one amino group of the diamino-bithia-zole ligand. O-H⋯O and N-H⋯O hydrogen bonds link the complexes into layers including the two uncoordinated water mol-ecules.

IIF9D8, a new monoclonal anti-idiotypic catalytic antibody with a CPA esterase-like activity was elicited by ID11D7, the monoclonal competitive inhibitory antibody to CPA. The hydrolysis of hippuryl-DL-phenyllactic acid by McAb IIF9D8 follows the Michaelis-Menten kinetics. The K-m value and k(cat) are 0.036 M and 0.598 min(-1), respectively, and the rate acceleration (k(cat)/k(uncat)) is 30500. Compared with the previous McAb 32C3 induced by polyclonal antibodies to CPA, McAb IIF9D8 shows higher catalytic efficiency. The catalytic antibodies with the catalytic properties similar to natural enzymes could be obtained by this approach. (C) 1999 Elsevier Science Ltd. All rights reserved.

Resonance Raman spectra of chlorosomes, isolated from the green bacteria Chloroflexus aurantiacus and Chlorobium tepidum, have been obtained with excitation in their near-infrared (Qy) absorption bands by using shifted-excitation Raman difference spectroscopy. Both spectra exhibit strong low-frequency (50−300 cm-1) modes, although these modes are relatively more intense in the Chloroflexus aurantiacus spectrum than in the Chlorobium tepidum spectrum. These intensity differences indicate that the low-frequency electron−nuclear coupling is strongest in the Chloroflexus aurantiacus chlorosome. The Raman spectrum of the Chloroflexus aurantiacus chlorosome is independent of excitation wavelength, and the scattering intensity tracks the absorption band and relative Raman intensities. A model comprised of more than one transition having similar vibronic parameters most successfully reproduces the Chloroflexus aurantiacus Qy absorption band shape. The resonance Raman mode frequencies and intensities agree qualita...
