An ionic organic–inorganic hybrid: tetrakis[bis(1,10-phenanthroline)copper(I)] dodecatungstophosphate(V)
Fan-Xia Meng,Hong-Bo Liu,Ya-Guang Chen
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536807062903
Abstract: Single crystals of the title polyoxometallate-based organic–inorganic hybrid, [Cu(C12H8N2)2]4[SiW12O40], were grown under hydrothermal conditions. The discrete [SiW12O40]4 anions are of the Keggin type and are packed in a slightly distorted orthorhombic F-centred mode, with the complex [CuI(phen)2]+ cations (phen is 1,10-phenanthroline) located in the voids of this arrangement. The four independent CuI cations are situated in the centres of more or less distorted tetrahedra made up of N atoms from the phen ligands. The anions and cations are linked together via weak hydrogen-bonding interactions, forming an extended three-dimensional network. Additional stabilization is achieved via π–π interactions between different phen molecules of adjacent [CuI(phen)2]+ cations with shortest distances between 3.416 and 3.499 .
Connotations and extensions of comparative effectiveness research and feasibility analysis for clinical evaluation in traditional Chinese medicine

Zhong Xi Yi Jie He Xue Bao , 2012,
Abstract: Comparative effectiveness research (CER) is well developed in international medical research. This article analyzes the basic connotations of CER from five aspects, including selection of objective, positioning of target population, comparison of intervention scheme, identification of contrast condition and analysis of therapeutic effects. The inclusiveness and advanced nature of CER were revealed by comparing with modern medical research methods, such as evidence-based medicine, patient-important outcome and randomized controlled trials. Based on the superiority of CER, the feasibility of applying CER in clinical evaluation of traditional Chinese medicine is explored. CER should be combined with the holistic concept, syndrome differentiation and individuality-concerned treatment so as to facilitate its development in research of traditional Chinese medicine in China.

Cross-Cultural Communication , 2007, DOI: 10.3968/640
Abstract: The cognitive schema is one of the topics in cognitive linguistics, and a cognitive pattern formed from the interaction between people and the outside world. Based on Lakoff’s cognitive schema theory, this paper compares the cognitive schema of spatial conceptualization of UP-DOWN in Russian and Chinese, and discusses the cognitive characteristics and meanings of the conceptualization of UP-DOWN by presenting the schemata in both the two languages. It proves that spatial conceptualization, as one of the basic experience of people, influences the structures and meanings of languages. Key words: spatial conceptualization, UP, DOWN, cognitive schema Résumé: Le modèle cognitif est une problématique de la linguistique cognitive et un moyen de cognition formé sur la base de l’interaction entre l’homme et le monde extérieur. Se référant à la théorie de George Lakoff, l’article présent compare les modèles russe et chinois sur la notion spatiale(avec l’exemple de haut-bas ), examine les caractéristiques cognitives et le sens de la notion haut-bas dans les deux langues et les démontrent de fa on graphique, pour prouver que la notion spatiale, comme une des expériences fondamentales de l’homme, influe la structure et le sens de la langue. Mots-clés: notion spatiale, haut , bas , modèle cognitif 摘要:認知模式是認知語言學研究的課題之一,是人與外部世界在互動的基礎上形成的認知方式。本文以萊考夫認知模式的主要理論為依據,比較俄漢語空間概念(以“上——下”為例)的認知模式,討論“上——下”概念在兩種語言中衍生的認知特點和含義並用圖式表示出來,證明了作為人的基本經驗之一的空間概念影響著語言的結構和意義。 關鍵詞:空間概念;“上”;“下”;認知模式
On the e$^+$e$^-$ excesses and the knee of the cosmic ray spectra -- hints of cosmic rays acceleration at young supernova remnants

Abstract: Supernova remnants have long been regarded as sources of the Galactic cosmic rays up to petaelectronvolts, but convincing evidence is still lacking. In this work we explore the common origin of the subtle features of the cosmic ray spectra, such as the knee of cosmic ray spectra and the excesses of electron/positron fluxes recently observed by ATIC, H.E.S.S., Fermi-LAT and PAMELA. Numerical calculation shows that those features of cosmic ray spectra can be well reproduced in a scenario with e$^+$e$^-$ pair production by interactions between high energy cosmic rays and background photons in an environment similar to the young supernova remnant. The success of such a coherent explanation serves in turn as an evidence that at least a portion of cosmic rays might be accelerated at young supernova remnants.
Attribute Reduction in Interval and Set-Valued Decision Information Systems  [PDF]
Hong Wang, Hong-Bo Yue, Xi-E Chen
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.411204
Abstract:

In many practical situation, some of the attribute values for an object may be interval and set-valued. This paper introduces the interval and set-valued information systems and decision systems. According to the semantic relation of attribute values, interval and set-valued information systems can be classified into two categories: disjunctive (Type 1) and conjunctive (Type 2) systems. In this paper, we mainly focus on semantic interpretation of Type 1. Then, we define a new fuzzy preference relation and construct a fuzzy rough set model for interval and set-valued information systems. Moreover, based on the new fuzzy preference relation, the concepts of the significance measure of condition attributes and the relative significance measure of condition attributes are given in interval and set-valued decision information systems by the introduction of fuzzy positive region and the dependency degree. And on this basis, a heuristic algorithm for calculating fuzzy positive region reduction in interval and set-valued decision information systems is given. Finally, we give an illustrative example to substantiate the theoretical arguments. The results will help us to gain much more insights into the meaning of fuzzy rough set theory. Furthermore, it has provided a new perspective to study the attribute reduction problem in decision systems.

A new ignition scheme using hybrid indirect-direct drive for inertial confinement fusion

Physics , 2013,
Abstract: A new hybrid indirect-direct-drive ignition scheme is proposed for inertial confinement fusion: a cryogenic capsule encased in a hohlraum is first compressed symmetrically by indirect-drive x-rays, and then accelerated and ignited by both direct-drive lasers and x-rays. A steady high-density plateau newly formed between the radiation and electron ablation fronts suppresses the rarefaction at the radiation ablation front and greatly enhances the drive pressure. Meanwhile, multiple shock reflections at the fuel/hot-spot interface are prevented during capsule deceleration. Thus rapid ignition and burn are realized. In comparison with the conventional indirect drive, the hybrid drive implodes the capsule with a higher velocity ($\sim4.3\times10^7$ cm/s) and a much lower convergence ratio ($\sim$25), and the growth of hydrodynamic instabilities is significantly reduced, especially at the fuel/hot-spot interface.

Abstract: In this study, a 47-day regional climate simulation of the heavy rainfall in the Yangtze-Huai River Basin during the summer of 2003 was conducted using the Weather Research and Forecast (WRF) model. The simulation reproduces reasonably well the evolution of the rainfall during the study period’s three successive rainy phases, especially the frequent heavy rainfall events occurring in the Huai River Basin. The model captures the major rainfall peak observed by the monitoring stations in the morning. Another peak appears later than that shown by the observations. In addition, the simulation realistically captures not only the evolution of the low-level winds but also the characteristics of their diurnal variation. The strong southwesterly (low-level jet, LLJ) wind speed increases beginning in the early evening and reaches a peak in the morning; it then gradually decreases until the afternoon. The intense LLJ forms a strong convergent circulation pattern in the early morning along the Yangtze-Huai River Basin. This pattern partly explains the rainfall peak observed at this time. This study furnishes a basis for the further analysis of the mechanisms of evolution of the LLJ and for the further study of the interactions between the LLJ and rainfall.

Laser Induced Damage Threshold at 355 and 1064nm of Ta2O5 Films of Different Phases

中国物理快报 , 2008,
Abstract: Ta2O5 films are deposited on fused silica substrates by conventional electron beam evaporation method. By annealing at different temperatures, Ta2O5 films of amorphous, hexagonal and orthorhombic phases are obtained and confirmed by x-ray diffractometer (XRD) results. X-ray photoelectron spectroscopy (XPS) analysis shows that chemical composition of all the films is stoichiometry. It is found that the amorphous Ta2O5 film achieves the highest laser induced damage threshold (LIDT) either at 355 or 1064nm, followed by hexagonal phase and finally orthorhombic phase. The damage morphologies at 355 and 1064nm are different as the former shows a uniform fused area while the latter is centred on one or more defect points, which is induced by different damage mechanisms. The decrease of the LIDT at 1064nm is attributed to the increasing structural defect, while at 355nm is due to the combination effect of the increasing structural defect and decreasing band gap energy.
