Intuitionistic trapezoidal fuzzy numbers and their operational laws are defined. Based on these operational laws, some aggregation operators, including intuitionistic trapezoidal fuzzy weighted arithmetic averaging operator and weighted geometric averaging operator are proposed. Expected values, score function, and accuracy function of intuitionitsic trapezoidal fuzzy numbers are defined. Based on these, a kind of intuitionistic trapezoidal fuzzy multi-criteria decision making method is proposed. By using these aggregation operators, criteria values are aggregated and integrated intuitionistic trapezoidal fuzzy numbers of alternatives are attained. By comparing score function and accuracy function values of integrated fuzzy numbers, a ranking of the whole alternative set can be attained. An example is given to show the feasibility and availability of the method.

In this paper, a general thermodynamic framework is developed to describe the thermo-chemo-mechanical interactions in elastic solids undergoing mechanical deformation, imbibition of diffusive chemical species, chemical reactions and heat exchanges. Fully coupled constitutive relations and evolving laws for irreversible fluxes are provided based on entropy imbalance and stoichiometry that governs reactions. The framework manifests itself with a special feature that the change of Helmholtz free energy is attributed to separate contributions of the diffusion-swelling process and chemical reaction-dilation process. Both the extent of reaction and the concentrations of diffusive species are taken as independent state variables, which describe the reaction-activated responses with underlying variation of microstructures and properties of a material in an explicit way. A specialized isothermal formulation for isotropic materials is proposed that can properly account for volumetric constraints from material incompressibility under chemo-mechanical loadings, in which inhomogeneous deformation is associated with reaction and diffusion under various kinetic time scales. This framework can be easily applied to model the transient volumetric swelling of a solid caused by imbibition of external chemical species and simultaneous chemical dilation arising from reactions between the diffusing species and the solid.

褪黑素是一种小分子神经递质,主要在脊椎动物的松果腺中合成与分泌,到达机体各部位来参与调控生物节律、生殖、生长与发育等生理过程。在鱼类中,松果腺是一个复合体,主要由类光感细胞构成,具有感光与内分泌双重功能。褪黑素的生物合成从色氨酸开始,涉及色氨酸羟化酶(TPH)、芳香族L-氨基酸脱羧酶(AAAD)、芳香烷胺-N-乙酰转移酶(AANAT)和乙酰色胺甲基转移酶(ASMT)。前期,我们通过对众多脊椎动物开展比较基因组学研究,发现这4个褪黑素合成酶系编码基因的系统进化与脊椎动物的物种进化基本一致,表明这些基因(同褪黑素一样)都很保守。有意思的是,在鱼类中各催化酶基因拷贝数出现显著增加,但四倍体与二倍体鱼中的拷贝数并不一定是2∶1,这是因为鱼类基因组复制后存在部分基因丢失的现象。此外,在大多数鱼类基因组中还鉴定到一些新基因,譬如aaad-like和asmt-like,可能拥有新的功能;有的催化酶基因缺失、出现移码突变或假基因化,可提升物种对特殊生境(诸如洞穴或深海)的生存适应性。本综述主要以我们团队近十年来的相关工作为主线,综合简介鱼类褪黑素合成酶系编码基因的系统进化与生理功能,以期深入理解褪黑素对鱼类生殖内分泌活动的影响,为进一步促进鱼类性腺发育、人工繁殖和分子育种等提供指导和支撑。

A mild and simple process for the effective oxidation of 5-hydroxymethylfurfural（HMF） into 2,5-diformylfuran（DFF） has been developed using Na NO2 as the oxidant. Some important reaction parameters were investigated to optimize the oxidation of HMF into DFF. It was found that the reaction solvent was very crucial for this reaction. Trifluoroacetic acid was the best solvent for the oxidation of HMF into DFF by Na *** the optimal reaction condition, almost quantitative HMF conversion and high DFF yield of 90.4% were obtained after 1 h at room temperature.

We investigate the evolutionary Prisoner＇s dilemma game on the simplest spatial networks constructed as geometrical graphs. The optimal cooperation enhancement against the topology randomness is found. It is proposed that the optimal behavior of the cooperation results from the competition between individuals with high degrees and with low degrees： the former assists the formation of cooperator clusters and the latter tends to prevent the formation of such dusters.
