Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812038901
Abstract: The crystal structure of the polymeric title complex, [Zn(C14H8O4)]n, is composed of layers parallel to (110) formed by linking of Zn–carboxylate chains with biphenyl units of the biphenyl-2,4′-dicarboxylate (bpdc) ligands. The ZnII atom is five-coordinated in a distorted square-pyramidal geometry by five O atoms from four bpdc ligands. The dihedral angle between the benzene rings is 52.32 (12)°.

Abstract: Objective: To study the serum proteomes of essential hypertension (EH) patients with abundant phlegm-dampness, and try to find special proteins associated with abundant phlegm-dampness syndrome.Methods: Fifty-nine hypertension patients were included, and the patients were divided into abundant phlegm-dampness syndrome group (39 cases) and non-phlegm-dampness syndrome group (20 cases). To find the special proteins associated with abundant phlegm-dampness, the EH patients with non-phlegm-dampness and another 30 healthy persons were regarded as control. Weak cation nano-magnetic beads were used to capture proteins in serum, and proteomic fingerprint was made by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). All the proteomic fingerprints were analyzed by Biomarker Wizard 3.1 Software. Then Biomarker Patterns Software (BPS) 5.0 was used to identify the differentiated proteins, which could induce phlegm-dampness.Results: There were 102 differentiated protein peaks between abundant phlegm-dampness and the control group. The best markers of abundant phlegm-dampness were protein peaks with the mass to charge ratio (m/z) of 9 334.958 m/z (the expression increased), 9 280.191 m/z (the expression decreased), 8 030.794 m/z (the expression increased), and 2 941.551 m/z (the expression increased). These four protein peaks found by BPS could induce abundant phlegm-dampness. They could be used to separate the abundant phlegm-dampness syndrome from the healthy persons and the hypertension patients with non-phlegm-dampness. The sensitivity of the model was 93.103% (27/29), specificity was 92% (23/25), false positive rate was 8% (2/25), false negative rate was 6.897% (2/29) and Youden’s index was 85.103%. Blind test data indicated a sensitivity of 90% (9/10) and a specificity of 88% (22/25), and the false positive rate was 12% (3/25), false negative rate was 10% (1/10), and Youden’s index was 78%.Conclusion: The differentiated proteins between the abundant phlegm-dampness group and the control group are the material foundation of abundant phlegm-dampness. The selected differentiated proteins can be used to distinguish the EH patients with abundant phlegm-dampness from the healthy persons and the EH patients with non-phlegm-dampness. The molecular biology diagnosis model can offer an objective and accurate way for TCM syndrome differentiation.

Abstract: By using SnCl2-2H2O and tetraethyl orthosilicate as raw materials, polystyrene colloidal crystal with diameter of 585nm as template, three-dimensional ordered macroporous (3DOM) SnO2 and SnO2/SiO2 were successfully synthesized. SEM observation shows that 3DOM SnO2 has a pore size of 453-500nm, and 3DOM SnO2/SiO2 has a pore size of 500nm. And such macropores connect with each other by small windows. Compared with the polystyrene colloidal crystal used, the 3DOM materials show shrinkage to some extent in pore size. The study indicates that it is difficult to obtain ordered pore structure when SnCl2 is used as precursor directly. But addition of tetraethyl orthosilicate or conversion of SnCl2 solution to oxi'de sol favors the formation of the highly ordered macroporous structure. XRD measurement indicates that the walls of the 3DOM materials are made of SnO2 nanoparticles with particle sizes around 17nm.

Abstract: 详细分析了新型高效3D圆阀的设计原理和特点.在1000 mm×350 mm规格的矩形实验塔中,应用典型的水-空气冷模实验系统对3D圆阀和F1型浮阀两种塔盘进行了对比实验研究,测定了多种气液负荷下两种圆形浮阀塔板的板压降、雾沫夹带和漏液量等流体力学性能.利用氧解吸法测定了两种浮阀塔板的传质效率.实验结果表明,在相同条件下,3D圆阀塔板的板效率比F1型浮阀塔板提高约20%左右,雾沫夹带量比F1型浮阀塔板略小,在工业应用范围内,3D圆阀的板压降和漏液量均比F1型浮阀小,是一种综合性能优良的新型圆阀.

Multi-proxy quantum group signature scheme with threshold shared verification

中国物理 B , 2008,
Abstract: A multi-proxy quantum group signature scheme with threshold shared verification is proposed. An original signer may authorize a proxy group as his proxy agent. Then only the cooperation of all the signers in the proxy group can generate the proxy signature on behalf of the original signer. In the scheme, any $t$ or more of $n$ receivers can verify the message and any $t-1$ or fewer receivers cannot verify the validity of the proxy signature.
Economical multiparty simultaneous quantum identity authentication based on Greenberger--Horne--Zeilinger states

中国物理 B , 2009,
Abstract: A multiparty simultaneous quantum identity authentication protocol based on Greenberger--Horne--Zeilinger (GHZ) states is proposed. The multi-user can be authenticated by a trusted third party (TTP) simultaneously. Compared with the scheme proposed recently (Wang et al 2006, Chin. Phys. Lett. 23(9) 2360), the proposed scheme has the advantages of consuming fewer quantum and classical resources and lessening the difficulty and intensity of necessary operations.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808009094
Abstract: The title compound, C30H26O4, is a dimer of 6,6′-dimethyldibenzo[d,f][1,3]dioxepine linked by formation of a C—C bond in the para position with respect to one O atom. The dimer is arranged around an inversion centre. As is usually observed in related compounds, the dibenzo group is twisted, the two benzene rings making a dihedral angle of 41.56 (9)°. The seven-membered ring exhibits a twisted conformation.
