Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536807062319
Abstract: The crystal structure of the title compound, C10H8N2·2C2H4O2, is built up from 4,4′-bipyridine and acetic acid molecules linked by strong O—H...N hydrogen bonds. The 4,4′-bipyridine and the two acetic acid molecules are further connected through weak C—H...O hydrogen bonds to form a supramolecular two-dimensional network parallel to the (001) plane. The two pyridine rings make a dihedral angle of 31.8 (1)°.

Cross-Cultural Communication , 2005, DOI: 10.3968/550
Abstract: In the long history of western literature there has long been a tradition of folly literature. I. B. Singer ,a distinguished contemporary Jewish writer ,fabricated a series of typical literature figures called fools in yiddish ,who are thought to be the original Jewish figures. One example is Gimple the Fool .By analyzing the “fool” in this article, we can see that Singer is always longing for the peaceful humanitarianism. Key words: I.B.Singer,fool, implication, the peaceful humanitarianism Résumé Dans la littérature occidentale existe une longue tradition de la littérature des imbéciles . I.B. Singer, célèbre écrivain juif contemporain des Etats-Unis, a créé une série d’ images imbéciles littéraires qui sont vues comme les modèles de la nation juive, et dont L’Imbécile Gimple est considéré comme le chef-d’oeuvre. En analysant l’image imbécile de cet ouvrage, l’article traite l’humanitarisme pacifique de Singer. Mots clés : I.B.Singer, l’imbécile, la signification, l’humanitarisme pacifique 摘 要 在西方文學中有一個源遠流長的“愚人文學”傳統。當代美國著名猶太作家辛格以垂死的猶太民族語言意第緒語,創造出了一系列被西方人認為是猶太民族原型的文學典型——愚者形象,《傻瓜吉姆佩爾》可謂其代表作。通過分析本文中的“傻瓜”形象,探討辛格的和平人道主義理想.。 關鍵詞: 辛格;傻瓜;意蘊;和平的人道主義

Abstract: The electronic structures of H,O and OH chemisorbed on Si nano-clusters were calculated with local density functional formalism. Atomic force calculations were used to reach at an optimized chemisorption site for the adsorbates. Different models were used. For all H adsorbed clusters, wider energy gaps are opened up compared with that of bulk Si, and quantum size effect is obviously shown. When a shell of the adsorbed H atoms is replaced by oxygen atoms, oxygen induced tail states appear in the gap. Both occupied and unoccupied states exist, and the gap is reduced from that in all H-terminated cases. For O atoms replaced by OH, the tail states become all occupied, but the gap widths do not differ much. No quantum size effects are observable for both O and OH adsorption.

Abstract: The reconstruction of diamond C(100) surface is studied with local density functional theory and extended numerical basis set. A cluster C49H36 is adopted to simulate the surface, where H atoms are saturation atoms. According to the calculation of forces exerted on the surface C atoms, an optimized C(100) surface atomic structure is achieved with the surface dimerized bond length, C-C, equals 1.415?. The nature of the bonding and the corresponding electronic structures, especially the distribution of surface states, are investigated and discussed.

Abstract: Microwave digestion and inductively coupled plasma mass spectrometry (ICP-MS) method was used to determine the contents of 25 inorganic elements in basal part, meat and shell of bamboo shoots. It could be concluded that the method could be applied to determine 25 inorganic elements in bamboo shoots. The elements with a dry basis content higher than 10 mg/kg were listed in the order of content decrease as follows, basal part of bamboo shoots: K > Ca > Mg > Mn > P > Al > Fe > Zn > Na; bamboo shoots meat: K > P > Ca > Mg > Mn > Fe > Al > Zn > Na > Ba > Sr; bamboo shoots shell: K > P > Mg > Ca > Mn > Al > Fe > Na > Zn; B, Pb, Cu, Cr ranged from 1.0 - 10 mg/kg; Ga, As, Se, Cd, Sn, Sb, V, Co, Ni were lower than 0.80 mg/kg. The harmful elements Cd, As, Cr, Hg, Pb were commonly monitored in feeds. The wet basis content (mg/kg) of Cd, As, Cr was lower than: 0.028, 0.022 and 0.42 respectively; no Hg was found; the content of Pb(mg/kg) in basal part, meat and shell of bamboo shoots was 0.82, 0.35 and 0.41 respectively. The results provide basic data for the development of bamboo shoots and its byproduct.

Journal of Nanomaterials , 2012, DOI: 10.1155/2012/607870
Abstract: Manganese dioxide nanostructures with controllable morphological structures and crystalline phases were synthesized via a facile hydrothermal route at low temperatures without using any templates or surfactants. Both the aging duration and aging temperatures were the main synthesis parameters used to influence and control the rate of morphological and structural evolution of MnO2 nanostructures. MnO2 nanostructures comprise of spherical nanoparticulate agglomerates and highly amorphous in nature were formed at lower temperature and/or short aging duration. In contrast, MnO2 nanostructures of sea-urchin-like and nanorods-like morphologies and nanocrystalline in nature were prepared at the combined higher aging temperatures and longer aging durations. These nanostructures underwent notable phase transformation from δ-MnO2 to α-MnO2 upon prolonged hydrothermal aging duration and exhibited accelerated rate of phase transformation at higher aging temperature.

Suh Cem Pang,Suk Fun Chin,Chian Ye Ling
Journal of Nanotechnology , 2011, DOI: 10.1155/2011/789305
Abstract: Thin films of manganese dioxide (MnO2) were prepared by self-assembly of MnO2 nanoparticles directly unto nickel-coated poly(ethylene terephthalate) flexible films using the newly developed horizontal submersion process. The thickness of deposited thin films was controllable by the deposition duration. This horizontal submersion deposition process for thin-film deposition is relatively easy, simple, and cost effective. Effects of deposition duration and calcination temperatures on the microstructure and electrochemical properties of self-assembled MnO2 thin films were investigated. Optimized MnO2 thin films exhibited high charge capacity, good cycling reversibility, and stability in a mild aqueous electrolyte and are thus promising electrode materials for the fabrication of thin-film electrochemical capacitors. 1. Introduction Manganese dioxide- (MnO2-) based thin film electrochemical capacitors have received numerous attentions since Pang et al. reported a specific capacitance value of 720?F/g for ultra-thin MnO2 films in a mild aqueous electrolyte [1, 2]. MnO2 thin films appear to be a promising electrode material in batteries and electrochemical capacitors due to the low cost of raw materials, low toxicity and environmentally benign, and their excellent electrochemical properties [3, 4]. Many routes for the preparation of MnO2 thin films have currently been developed, which include the sol-gel process, electrodeposition [5–7], and atomic layer deposition [8]. More recently, the self-assembly technique has emerged as one of the most promising methods for thin film fabrication [9]. Self-assembly is the spontaneous adsorption process by which molecules or nanoparticles are arranged into organized aggregates, networks, or patterns onto a supporting substrate. It is characterized as being relatively simple, inexpensive, and requires low energy consumption. In this study, we have attempted to prepare self-assembled manganese dioxide (MnO2) thin films directly on nickel-coated poly(ethylene terephthalate) (Ni/PET) flexible supporting substrate using the newly developed horizontal submersion process under ambient conditions. This thin film deposition process is very cost effective, rapid, and conformal in the preparation of nanostructured thin films which are suitable for the fabrication of thin film electrochemical capacitors. Most notably, the thickness of deposited film is controllable simply by the duration of submersion or by repeating the deposition process a desired number of times.

Detection of Outliers and Patches in Bilinear Time Series Models
Ping Chen,Ling Li,Ye Liu,Jin-Guan Lin
Mathematical Problems in Engineering , 2010, DOI: 10.1155/2010/580583
Abstract: We propose a Gibbs sampling algorithm to detect additive outliers and patches of outliers in bilinear time series models based on Bayesian view. We first derive the conditional posterior distributions, and then use the results of first Gibbs run to start the second adaptive Gibbs sampling. It is shown that our procedure could reduce possible effects on masking and swamping. At last, some simulations are performed to demonstrate the efficacy of detection and estimation by Monte Carlo methods.
