A rational design of efficient low-band-gap non-fullerene acceptors(NFAs)for high-performance organic solar cells(OSCs)remains challenging;the main constraint being the decrease in the energy level of the lowest unoccupied molecular orbitals(LUMOs)as the bandgap of A-D-A-type NFAs ***,the short current density(J_(sc))and open-circuit voltage(V_(oc))result in a trade-off relationship,making it difficult to obtain efficient ***,three NFAs(IFL-eD-4 F,IDT-eD-4 F,and IDTT-eD-2 F)were synthesized to address the above-mentioned issue by introducing 3,4-ethylenedioxythiophene(eDOT)as aπ-*** NFAs exhibit relatively low bandgaps(1.67,1.42,and 1.49 eV,respectively)and upshifted LUMO levels(-3.88,-3.84,and-3.81 eV,respectively)compared with most reported low-band-gap ***,the photovoltaic devices based on IDT-eD-4 F blended with a PBDB-T donor polymer showed the best power conversion efficiency(PCe)of 10.4%with a high J_(sc) of 22.1 mA cm^(-2) and Voc of 0.884 V among the examined *** contrast,IDTT-eD-4 F,which was designed with an asymmetric structure of the D-p-A type,showed the lowest efficiency of 1.5%owing to the poor morphology and charge transport properties of the binary ***,when this was introduced as the third component of the PM6:BTP-BO-4 Cl,complementary absorption and cascade energy-level alignment between the two substances could be ***,the IDTT-eD-4 F-based ternary blend device not only improved the Jscand Voc,but also achieved a PCe of 15.2%,which is approximately 5.3%higher than that of the reference device with a minimized energy loss of 0.488 *** addition,the universality of IDTT-eD-2 F as a third component was effectively demonstrated in other photoactive systems,specifically,PM6:BTPe C9 and PTB7-Th:ieICO-4 *** work facilitates a better understanding of the structure–property relationship for utilizing efficient eDOT-bridged NFAs in high-performance OSC applications.

The rapid technological convergence between Internet of Things （loT）, Wireless Body Area Networks （WBANs） and cloud computing has made e-healthcare emerge as a promising application domain, which has significant potential to improve the quality of medical care. In particular, patient-centric health monitoring plays a vital role in e-healthcare service, involving a set of important operations ranging from medical data collection and aggregation, data transmission and segregation, to data analytics. This survey paper firstly presents an architectural framework to describe the entire monitoring life cycle and highlight the essential service components. More detailed discussions are then devoted to {／em data collection} at patient side, which we argue that it serves as fundamental basis in achieving robust, efficient, and secure health monitoring. Subsequently, a profound discussion of the security threats targeting eHealth monitoring systems is presented, and the major limitations of the existing solutions are analyzed and extensively discussed. Finally, a set of design challenges is identified in order to achieve high quality and secure patient-centric monitoring schemes, along with some potential solutions.

This paper proposes an optimal tracking control of completely unknown affine nonlinear systems using a system augmentation scheme and a modified discounted performance function, where the feedforward and feedback control actions can be obtained simultaneously. We first present an adaptive identifier to estimate the unknown dynamics, where the estimated parameters are updated based on a new adaptive law such that these estimated parameters converge to a small neighborhood around their true values. An augmented system consisting of the tracking error and the generator of the trajectory to be tracked are then constructed, which derives an augmented tracking Hamilton-Jacobi-Bellman（HJB） equation. An online critic neural network（NN） is finally presented to approximate the optimal value function of HJB equation, and then calculate the optimal control action. This leads to an identifier-critic based adaptive dynamic programming（ADP） structure. Simulation results are presented to demonstrate the effectiveness of the proposed method.

In this paper, precise tracking control of a class of high-order hydraulic servo systems is studied, where the dynamics of the electrohydraulic actuator are considered. Different to available results, a new control method is proposed without using the backstepping scheme and any function approximators. The model of the hydraulic servo system is transformed into a Brunovsky form, so that the tracking control of the original system can be carried out by controlling the transformed system. In this case, the widely-used backstepping scheme is avoided. The Levant’s differentiator is then employed to observe the unknown system states of the transformed system. Finally, an unknown dynamics estimator is constructed and then incorporated into the feedback control, which avoids using function approximators（e.g. neural network, fuzzy systems） for addressing unknown nonlinearities. Only the output of the original system needs to be measured. The closed-loop control system stability is rigorously proved. Simulation results based on a realistic plant are provided to illustrate the effectiveness of the proposed control method.

Ryanodine receptors（RyRs） activator has become one class of popular insecticide because of its unique mode of action. In order to find more new RyRs activators as insecticidal agents, a series of 18 novel chiral anthranilic diamides were designed by introducing the D-alanine acid and D-serine acid esters as well as trifluoroethoxyl group into the anthranilic diamide skeleton and synthesized successfully based on anthranilic diamide and FKI-1033 structures. The structures of the title compounds Ia–i and IIa–i were confirmed by melting points,~1H NMR,^（13）C NMR, elemental analysis and specific optical rotation *** preliminary bioassay results indicated that most of the title compounds exhibited considerable larvicidal activities against oriental armyworm at 10 mg/L, especially Ib, ie and IIh showed remarkable insecticidal activities at 0.5 mg/L. The larvicidal activity against diamondback moth of Ia and IId were 80%and 90% respectively at 0.0001 mg/L, which was similar to that of chlorantraniliprole. The relationship between structure and insecticidal activity was analyzed to reveal a possible co-regulated effect of the chiral amino acid ester, halogen atom or cyano group, and trifluoroethyloxyl group of the skeleton structures of the title compounds, which will provide useful information for guiding the design and discovery of new RyRs activators and insecticidal agrochemicals.

Design, Synthesis, Biological evaluation and SARs of Novel N-Substituted Sulfoximfnes as Potential Ryanodine Receptor Modulators

Chinese Journal of Chemistry 2018年第2期36卷 129-133页

The sulfoximine group has been evaluated as a pharmacophore. Introducing the sulfoximine structure into medicinal compounds as exciting motifs has brought opportunities in drug discovery. In order to develop new ryanodine receptor （RyR） modulators, a series of phthalamides containing sulfoximine derivatives were designed, synthesized, and evaluated against oriental armyworm and diamondback moth for their insecticidal activities. These studies helped to elucidate the electronic and structural requirements around the sulfoximine motif for insecticidal activity. All new structures were synthesized and characterized by ^1H NMR, ^13C NMR, HRMS and bioassay and a preliminary structure-activity relationship （SAR） was discussed. The biological assessment indicated that most title compounds showed good to excellent larvicidal activities. Compounds la, le, and If gave excellent insecticidal activity against oriental armyworm, which showed 100% larvicidal activity at 0.5 mg/L. All compounds showed 100% larvicidal activity at 0.1 mg/L against diamondback moth. In particular, the larvicidal activities of le, If, and lh at 0.0001 mg/L were 50%, 20%, and 40%, respectively, reaching an activity as high as that of the commercial flubendiamide （40%, 0.0001mg/L）. Therefore, Ia, ie, If and Ih could be considered as new lead structures for the development of new ryanodine receptor （RyR） modulators.

深入研究了在1 550和1 330nm波长条件下光纤传输中机械对准误差导致的损耗问题。MATLAB仿真结果表明:高阶模比低阶模有更严重的衰减,单模光纤横向对准误差是最严重的损耗因素;较大的数值孔径时角度对准误差导致的耦合损耗减小,而在数值孔径一样时匹配液折射率越高耦合效率越低,这与端面间隙导致的损耗影响相反。文中的研究对于光纤通信的稳定性发展具有一定的理论和实际意义。

19世纪末20世纪初,伴随《共产党宣言》在东亚的知识旅行,马克思主义中用以描述革命对象的"Kapitalist(en)"(资本家)和"Bourgeois(ie)"(资产阶级)概念进入中国语境,并在1920年以后迅速成为中国革命话语体系中的重要组成部分。《共产党宣言》中国化的过程也是一个概念中国化的过程,它的东传不可简单地理解为一个文本的知识旅行,还有肇启亚洲革命的作用。随着《共产党宣言》汉译本的变迁,"Kapitalist(en)"和"Bourgeois(ie)"的译词及其内涵也经历了从突出道德、社会、经济内涵向突出政治阶级斗争的转变,与之对应的是不同时期中国革命者关于中国革命对象的不同描述。
