Journal of Integrative Plant Biology 2015年第8期57卷 673-687页

作者： Kai Fan Hao Shen Noreen bibi Feng Li Shuna Yuan Ming Wang Xuede Wang Institute of Crop Science College of Agriculture and Biotechnology Zhejiang University

he NAP（NAC-Like, Activated by AP3/PI） subfamily is one of the important plant-specific transcription factors, and controls many vital biological processes in plants. In the current study, 197 NAP proteins were identified from 31 vascular plants,but no NAP members were found in eight non-vascular *** NAP proteins were phylogenetically classified into two groups（NAP I and NAP II）, and the origin time of the NAP I group might be relatively later than that of the NAP II ***, species-specific gene duplications, caused by segmental duplication events, resulted in the expansion of the NAP subfamily after species-divergence. Different groups have different expansion rates, and the NAP group preference was found during the expansion in plants. Moreover, the expansion of NAP proteins may be related to the gain and loss of ***, functional divergence was limited after the gene duplication. Abscisic acid（ABA） might play an important role in leaf senescence, which is regulated by NAP subfamily. These results could lay an important foundation for expansion and evolutionary analysis of NAP subfamily in plants.

Present contribution is concerned with the construction and application of a numerical method for the fluid flow problem over a linearly stretching surface with the modification of standard Gradient descent Algorithm to solve the resulted difference *** flow problem is constructed using continuity,and Navier Stoke equations and these PDEs are further converted into boundary value problem by applying suitable similarity transformations.A central finite difference method is proposed that gives third-order accuracy using three grid *** stability conditions of the present proposed method using a Gauss-Seidel iterative procedure is found using Von-Neumann stability criteria and order of the finite difference method is proved by applying the Taylor series on the discretised *** comparison of the presently modified optimisation algorithm with the Gauss-Seidel iterative method and standard Newton’s method in optimisation is also *** can be concluded that the presently modified optimisation Algorithm takes a few iterations to converge with a small value of the parameter contained in it compared with the standard descent algorithm that may take millions of iterations to *** present modification of the steepest descent method converges faster than Gauss-Seidel method and standard steepest descent method,and it may also overcome the deficiency of singular hessian arise in Newton’s method for some of the cases that may arise in optimisation problem(s).

Graphene has become a worldwide admired material among researchers and scientists equally due to its unique richness in mechanical strength, electrical conductivity, optical and thermal properties. Re- searchers have explored that the composite materials based on graphene and metal/metal oxide nanostructures possess excellent potential for energy storage technologies. In particular, supercapacitors based on such composite materials have engrossed the extreme interest of researchers for its rapid charging/discharging time, safe operation and longer cyclic constancy. Till now, several fabrication techniques for composite materials and their energy storage applications have been explored. Here, specially, we have concentrated on the hottest research progress for the fabrication of graphene oxide and metal/metal oxide nanocomposites. We also emphasized on the characteristics and properties of supercapacitors fabricated using these composite materials. Moreover, our study is focused on the specific capacitance and cyclic stability of various composites to haul out the most efficient material for supercapacitor applications.

Function of note strings in Japanese Tit alarm calls to the Common Cuckoo:a playback experiment

Avian Research 2017年第3期8卷 141-146页

Background: Birds produce alarm calls to convey information about threats. Some Passerine alarm calls consist of several note strings, but few studies have examined their function. Previous studies have shown that Japanese Tits(Parus minor) can alter the calling rate and number and combination of notes in response to predators. We previously found the combinations of note types in Japanese Tit alarm calls to be significantly different in response to the Sparrowhawk(Accipiter nisus) and Common Cuckoo(Cuculus canorus).Methods: Through playback experiments, we tested whether the note strings in Japanese Tit alarm calls to the Common Cuckoo have different functions in conveying information. The note strings of selected alarm calls were divided into the categories of C and D, and different calls were then constructed separately based on the two note string categories. Original alarm calls(C–D), C calls and D calls were played back to male Japanese Tits during the incubation ***: Male Japanese Tits had a significantly stronger response to C calls than to C–D calls, and they showed a significantly stronger response to both C and C–D calls than to D calls, suggesting that Japanese Tits discriminated between the C and D ***: Our study demonstrated that the C-and D-category note strings of Japanese Tit alarm calls to the Common Cuckoo have different functions, which supports the previous finding that different note strings in an alarm call can provide different information to receivers. However, the exact meanings of these note strings are not yet known, and further investigation is therefore required.

开发了一种磁性Fe_3O_4纳米粒子和2-(3,4-二羟苯基)苯并噻唑(DPB)修饰的磁性棒碳糊电极(MBCPE)用于电化学检测肼.首先将DPB自组装在Fe_3O_4纳米粒子上,然后将此复合物吸附于设计的MBCPE上.MBCPE电极将磁性纳米粒子吸引到电极表面.所得新型电极具有高的导电性和大的有效比表面积,因而对肼的电催化氧化反应有非常大的电流响应.采用伏安法、扫描电镜、电化学阻抗谱、红外光谱和紫外-可见光谱对修饰电极进行了表征.采用伏安法研究了在磷酸盐缓冲溶液(pH=7.0)中MBCPE/Fe_3O_4NPs/DPB电极上肼的电化学行为.作为电化学传感器,MBCPE/Fe_3O_4NPs/DPB电极对肼氧化反应表现出极高的电催化活性.在DPB存在下,肼的氧化电势下降,但其催化电流增加.电催化电流与肼浓度在0.1–0.4和0.7–12.0μmol/L二个区间内表现出线性关系,检测限为18.0 nmol/L.另外,研究了MBCPE/Fe_3O_4NPs/DPB电极同时检测肼和苯酚的性能.伏安实验结果显示,苯酚的线性区域为100–470μmol/L,检测限为24.3μmol/L.采用此电极检测了水样品中的肼和苯酚.
