Multi-level Evaluation of Load Supply Adequacy for Transmission Network  [PDF]
Zheng-lin Yang, Jian-guo Yao, Jian Geng
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.54B141
Abstract:

Considering sharp increase of central integration scale of intermittent energy generation, power system couldn’t rely on the determined model based operation schedule to assure its reliable load supply. Then, this article presents a new load supply adequacy evaluation method, which based on continuous security constrained generation optimization, and provides the functional architecture design of online multi-level short term load supply adequacy evaluation system.

A general method for identifying node spreading influence via the adjacent matrix and spreading rate
Jian-Hong Lin,Jian-Guo Liu,Qiang Guo
Computer Science , 2014,
Abstract: With great theoretical and practical significance, identifying the node spreading influence of complex network is one of the most promising domains. So far, various topology-based centrality measures have been proposed to identify the node spreading influence in a network. However, the node spreading influence is a result of the interplay between the network topology structure and spreading dynamics. In this paper, we build up the systematic method by combining the network structure and spreading dynamics to identify the node spreading influence. By combining the adjacent matrix $A$ and spreading parameter $\beta$, we theoretical give the node spreading influence with the eigenvector of the largest eigenvalue. Comparing with the Susceptible-Infected-Recovered (SIR) model epidemic results for four real networks, our method could identify the node spreading influence more accurately than the ones generated by the degree, K-shell and eigenvector centrality. This work may provide a systematic method for identifying node spreading influence.
Empirical Analysis of the Online Rating Systems
Xin-Yi Lu,Jian-Hong Lin,Qiang Guo,Jian-Guo Liu
Computer Science , 2015,
Abstract: This paper is to analyze the properties of evolving bipartite networks from four aspects, the growth of networks, the degree distribution, the popularity of objects and the diversity of user behaviours, leading a deep understanding on the empirical data. By empirical studies of data from the online bookstore Amazon and a question and answer site Stack Overflow, which are both rating bipartite networks, we could reveal the rules for the evolution of bipartite networks. These rules have significant meanings in practice for maintaining the operation of real systems and preparing for their future development. We find that the degree distribution of users follows a power law with an exponential cutoff. Also, according to the evolution of popularity for objects, we find that the large-degree objects tend to receive more new ratings than expected depending on their current degrees while the small-degree objects receive less ratings in terms of their degrees. Moreover, the user behaviours show such a trend that the larger degree the users have, the stronger purposes are with their behaviours except the initial periods when users choose a diversity of products to learn about what they want. Finally, we conclude with a discussion on how the bipartite network evolves, which provides guideline for meeting challenges brought by the growth of network.
Locating influential nodes via dynamics-sensitive centrality
Jian-Hong Lin,Qiang Guo,Jian-Guo Liu,Tao Zhou
Computer Science , 2015,
Abstract: With great theoretical and practical significance, locating influential nodes of complex networks is a promising issues. In this paper, we propose a dynamics-sensitive (DS) centrality that integrates topological features and dynamical properties. The DS centrality can be directly applied in locating influential spreaders. According to the empirical results on four real networks for both susceptible-infected-recovered (SIR) and susceptible-infected (SI) spreading models, the DS centrality is much more accurate than degree, $k$-shell index and eigenvector centrality.

trans,trans,trans-Diaquabis(nicotinamide-κN)bis(2-nitrobenzoato-κO)cadmium(II) dihydrate
Kou-Lin Zhang,Bo Yang,Jian-Guo Lin,Seik Weng Ng
Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809005479
Abstract: The cadmium atom in the title compound, [Cd(C7H4NO4)2(C6H6N2O)2(H2O)2]·2H2O, lies on a center of inversion in an all-trans octahedral environment. In the crystal, the complex interacts with the uncoordinated water molecules through O—H...O and N—H...O hydrogen bonds, forming a layered network.

Kou-Lin Zhang,Jian-Guo Lin,Seik Weng Ng
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812003467
Abstract: The 4-sulfophthalate trianion in the polymeric complex, {[Er(C8H3O7S)(C12H8N2)(H2O)2]·2H2O}n, bridges three water/phenanthroline-coordinated ErIII ions to form a three-dimensional network architecture. The metal atom is further chelated by a carboxylate group and is covalently bonded to a monodentate carboxylate group as well as to a monodentate sulfonate group in a distorted square antiprismatic geometry. The coordinating water molecules and the lattice water molecules, one of which is disordered over two positions [major component 65 (3)%], are hydrogen bonded to the network.

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536808040622
Abstract: In the title compound, C11H14N2O5, the nitro group is approximately coplanar with the benzene ring, making a dihedral angle of 4.26 (17)°. The dihedral angle between the methylcarbamate group and the benzene ring is 72.47 (6)°. There is a strong intermolecular N—H...O hydrogen bond between the N and O atoms from adjacent methylcarbamate groups, forming a one-dimensional network along the a axis.

The coordinating and the solvent water molecules are hydrogen bonded to the network. In the crystal, one solvent water molecule is disordered over two positions [major component = 59 (3)%].
Synthesis and Antitumor Activity of 3-Methyl-4-oxo-3,4-dihydroimidazo [5,1-d][1,2,3,5]tetrazine-8-carboxylates and -carboxamides
Dan Liu,Jian-Guo Yang,Jie Cheng,Lin-Xiang Zhao
Molecules , 2010, DOI: 10.3390/molecules15129427
Abstract: Seventeen novel 3-methyl-4-oxo-3,4-dihydroimidazo[5,1-d][1,2,3,5]tetrazine-8-carboxylate and -carboxamide derivatives were synthesized and evaluated for their growth inhibition in seven human solid tumor and a human leukemia HL-60 cell lines. Compound IVa showed more activity than the other compounds and the positive control temozolomide. In the presence of 40 mg/mL of IVa, the survival rate of all tested tumor cells was less than 10%. Esters displayed more potent antitumour activity than amides and temozolomide against HL-60 cells. These compounds also exhibited considerably enhanced water-solubility.
