Abstract: Based on statistics of industrial pollutant yields and discharge quantity in Jilin Province, the non-residual decomposition model was applied to quantify the net amount of environmental benefits of clean production and end-pipe treatment respectively. Environmental performances of end-of-pipe and pollution prevention strategies were further analyzed to explore an appropriate way of improving regional industrial ecological transition. The results showed that industrial symbiosis did not exert a positive effect on environment improvement. Technical factor promoted environmental performance improvement in clean production, while both technical factor and scale factor did in end-pipe treatment. Clean production was superior to end-pipe treatment in pollution volume reduction, which implied that prevention strategy dominated over end-of-pipe strategy, but the improvement of clean production tended to slow down. It is necessary to construct a proper industrial ecological system for the realization of environmental goals.

Abstract: We have carried out theoretical investigations on the electronic structure of GaAs(311)A and GaAs(311)B surfaces. The bulk electronic structure of GaAs has been described by the second-neighbour tight-binding formalism and the surface electronic structure was evaluated via an analytic Green function method. First, we present the surface band structure together with the projected bulk band of both Ga-terminated and As-terminated for GaAs(311)A and GaAs(311)B surfaces, respectively. In each case, the number of surface states is determined, and the localized surface features and orbital properties of these surface states along Γ-Y-S-X-Γ high symmetry lines of the surface Brillouin zone are discussed. For the Ga-terminated GaAs(311)A (1×1) surface, we have tested two possible structure models, i.e. "the bridge site" and "the hollow site" models. In comparison with the angle-resolved photoelectron spectroscopy studied recently, the results have shown that the surface electronic states of the hollow site model are in good agreement with the experiments, whereas those of the bridge site model are not. So we have concluded that the hollow site model is favourable for the Ga-terminated GaAs(311) (1×1) surface and the bridge site model should be excluded.

The beneficial effects of RAS inhibition on the development of diabetes have been largely attributed to improvements in peripheral insulin sensitivity and glucose metabolism. This review focuses on recent experimental and clinical evidence supporting the role of RAS inhibition in the reduction of new onset type 2 diabetes and the mechanisms that may be involved.
Enhanced Quantum Reflection of Ultracold Atoms with Strong Interatomic Interaction

中国物理快报 , 2008,
Abstract: We calculate the reflection probability for ultracold alkali atoms incident on a solid surface. By considering the interatomic interaction and using the WKB method, it is shown that the repulsive interaction between atoms has the effect of increasing the reflection probability. The increasing amplitude is related with the interatomic interaction and the depth of atom-surface potential. In addition, we also perform a numerical calculation to testify the effect of the interatomic interaction, and the analytic result is proven by the numerical result.

Morphological variation of Mesobuthus martensii (Karsch, 1879) (Scorpiones: Buthidae) in Northern China.

Euscorpius , 2009,
Abstract: Comparative statistical analysis of morphology of Mesobuthus martensii and Mesobuthus eupeus (Scorpiones: Buthidae) indicated highly significant differences between these two species. Mann-Whitney U test showed that: except Ca_L/AW, Ca_AW/PW and Met-V_L/H in female, Ca_AW/PW and Met-V_L/H in male, all morphometric ratios demonstrated significant differences between M. martensii and M. eupeus. Principal component analysis (PCA) showed that M. martensii and M. eupeus are clearly different species in morphology. Three statistical analyses (Kruskal-Wallis one-way ANOVA, PCA and cluster analysis) were applied to M.martensii from 27 confirmed localities in five provinces of northern China. The results suggested that: (a) Although M. martensii is common and widespread in northern China, its morphology does not vary significantly, but there is more variation in females than males, and the variation both in males and females is below species level; (b) the populations from Hebei, Ningxia, Inner Mongolia, and Liaoning Provinces were similar to each other while the populations from Qinghai were separated from the others; (c) except Met-I_L/W and Met-V_L/W, each ratio of metasoma in both females and males of Qinghai populations was smaller and the ratio of Ca_L/AW was larger than those from other provinces.
Quantum state transfer from light to molecules via coherent two-color photo-association in an atomic Bose-Einstein condensate
Hui Jing,Ming-Sheng Zhan
Physics , 2005,
Abstract: By using a quantized input light, we theoretically revisit the coherent two-color photo-association process in an atomic Bose-Einstein condensate. Under the single-mode approximations, we show two interesting regimes of the light transmission and the molecular generation. The quantum state transfer from light to molecules is exhibited, without or with the depletion of trapped atoms.

Ni Li,Ming-Sheng Liu
Mathematics , 2015,
Abstract: In this paper, we first establish several general sufficient conditions for the biholomorphic convex mappings on the bounded convex balanced domain $D_{p}^n(p_{j}\geq 2,j=1,\cdots,n)$ in $C^{n}$, which extend some related results of earlier authors. From these, some concrete examples of biholomorphic convex mappings on $D_{p}^n$ are also provided.

Abstract: Aims Our objectives were to analyze differences of grain yield, water use efficiency (WUE) and stable carbon isotope ratio (δ13C) in various genotypes of dryland winter wheat (Triticum aestivum) and the correlation between δ13C value and grain yield and WUE under two different ecological conditions. Findings will help clarify the reliability of using δ13C to evaluate WUE and provide a basis for breeding water-saving types. Methods We studied 15 winter wheat genotypes (12 from north China and 3 from Texas, USA) on the Loess Plateau of East Gansu under dryland and supplemental irrigation treatments at the jointing stage. Important findings Different genotypes had considerable differences in grain yield, WUE and δ13C value whether under dryland or irrigation, and the δ13C value increased with grain filling proceeding. Moreover, the δ13C value under dryland condition was higher than under limited irrigation. The correlation between δ13C with grain yield and WUE is significant during the grain filling stages whether under dryland or irrigation, and the correlation under dryland is better than that under limited irrigation. With irrigation of 100 mm water at jointing stage, various genotypes of winter wheat had significant compensation or super compensation effects. The δ13C value can indicate WUE well whether under dryland or irrigated condition. Therefore, the δ13C value can be used by breeding programs as a potential selection criterion for grain yield and WUE in wheat.
Similarity-Based Classification in Partially Labeled Networks
Qian-Ming Zhang,Ming-Sheng Shang,Linyuan Lu
Physics , 2010, DOI: 10.1142/S012918311001549X
Abstract: We propose a similarity-based method, using the similarity between nodes, to address the problem of classification in partially labeled networks. The basic assumption is that two nodes are more likely to be categorized into the same class if they are more similar. In this paper, we introduce ten similarity indices, including five local ones and five global ones. Empirical results on the co-purchase network of political books show that the similarity-based method can give high accurate classification even when the labeled nodes are sparse which is one of the difficulties in classification. Furthermore, we find that when the target network has many labeled nodes, the local indices can perform as good as those global indices do, while when the data is sparce the global indices perform better. Besides, the similarity-based method can to some extent overcome the unconsistency problem which is another difficulty in classification.
