In this Letter, we realized an enhanced optical rotation of the zero-order transmitted light through a silver film with an array of perforated S-shaped holes. Different from the previous studies, this effect results from the contribution of both the localized surface plasmons and surface plasmon polaritons (SPPs). The rotation angle can be modulated with the thickness due to the phase retardation of the SPPs when tunneling to the emitted surface. With a sample thickness 245 nm, a near-complete cross-polarization conversion (90 optical rotation) can be achieved, representing a major advance in performance compared to the previously reported planar chiral structures. © 2013 American Physical Society.

BiOI sensitized nano-Bi2WO6 photocatalysts with different BiOI contents were successfully synthesized by a facile deposition method at room temperature, and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) high-resolution transmission electron microscopy (HR-TEM), photoluminescence (PL) spectra, UV-vis diffuse reflection spectroscopy (UV-vis DRS) and Brunauer-Emmett-Teller (BET) surface area measurements. The photocatalytic activity of BiOI/Bi2WO6 was evaluated by the photo-degradation of Reactive Brilliant Red (X-3B) in suspended solution and toluene in gas phase. It has been shown that the BiOI/Bi2WO6 catalysts exhibit a coexistence of both tetragonal BiOI and orthorhombic Bi2WO6 phases. With increasing BiOI content, the absorption intensity of BiOI/Bi2WO 6 catalysts increases in the 380-600 nm region and the absorption edge shifts significantly to longer wavelengths as compared to pure Bi 2WO6. The 13.2% BiOI/Bi2WO6 catalyst exhibits obviously higher UV and visible light photocatalytic activities than commercial P25, pure Bi2WO6 and BiOI, for the photodegradation of toluene and X-3B. The remarkably enhanced photocatalytic activities can be attributed to the fact that the proper BiOI sensitized nano-Bi2WO6 increase its BET surface area, decrease band-gap energy, enhance absorption in the 380-600 nm region and inhibit the recombination of photo-induced carriers. © 2012 Elsevier B.V.

This paper studies numerically the temperature reached by atomic force microscope tips illuminated by femtosecond laser pulses, in which the laser focusing dependence of tip heating is investigated in detail and the laser heating effects on different tips are discussed too. The results show that tip heating can be significantly reduced if the femtosecond laser is focused tightly on the tip apex. © 2010 EDP Sciences.

We consider the discrete-time Markovian single-server queue under delayed multiple vacations. Upon arriving, the customers observe the queue length and decide whether to join or balk. We derive equilibrium threshold balking strategies in two cases, according to the information for the server's state. We also illustrate the equilibrium thresholds and the social benefits for systems via numerical experiments. © EDP Sciences, ROADEF, SMAI 2016.

This paper studies of B/S mode application model and provide relative function design modules for online English Multimedia teaching system. The system is based on J2EE technology. The development of Web layer, business logic layer and data layer for function module are discussed in detail. By the research on system structure, processing model, structured analysis techniques and object-oriented analysis we obtain the main demand and non-functional demand of system. Then according system design rules, we describe the main modules by system foreground and background data management system, to offer a detailed structure designed scheme. The system tests show that the system in this paper can well adapt the actual characteristics of online open English teaching, and meet the demand for teaching assistant functions. © 2015 IEEE.

English course online learning system is designed, the function of which includes the management function (personnel management, question library management, courseware management, security management, bulletin management and resource management), online learning (PPT, teaching video, difficulty parsing, homework problem), online test (randomly selected topic, automatic marking, chapter practice) and BBS communication. In the process of design, the MVC design pattern based on the Struts framework is used and data persistence technology uses Hibernate framework. Practice proves that the learning system has the characteristic of security, stability, high performance, cross-platform and expansion, which meets the requirements of the university students' learning. The entire system can allow students to study online. © 2015 IEEE.

Small heat shock proteins (sHSPs) are the most diverse but also the most poorly known family of molecular chaperones, and they play essential roles in various biological processes. The striped stem borer, Chilo suppressalis (Insecta: Lepidoptera: Pyralidae), is one of the most serious pests of rice, causing extensive damage and yield loss. In this study, we isolated and characterized five members of the sHSPs family - Cshsp19.8, Cshsp21.4, Cshsp21.5, Cshsp21.7a, and Cshsp21.7b - from C. suppressalis. The cDNAs of these genes encoded proteins of 177, 187, 191, 191, and 191 amino acids with isoelectric points of 7.0, 5.6, 6.1, 6.3, and 6.3, respectively. While Cshsp19.8, Cshsp21.5, and Cshsp21.7b had no introns, Cshsp21.4 and Cshsp21.7a contained one and two introns, respectively. Structural analysis indicated that all five Cshsps possessed conserved arginine and a V/IXI/V motif, which is related to hydrophobic characteristics of sHSPs. The five heat shock proteins can be classified into two main groups: an orthologous type (Cshsp21.4 and Cshsp21.7a) and a species-specific type (Cshsp19.8, Cshsp21.5, and Cshsp21.7b). Real-time quantitative PCR analyses revealed that Cshsp19.8, Cshsp21.5, Cshsp21.7a, and Cshsp21.7b all exhibited their highest expression levels within Malpighian tubules or the hindgut, while such levels were found in the head for Cshsp21.4. The expression of Csshsps at different developmental stages revealed that the mRNA levels of Cshsp19.8, Cshsp21.4, Cshsp21.5, and Cshsp21.7b peaked in adults, whereas the highest level of Cshsp21.7a was observed in first instar larvae. Cshsp19.8 and Cshsp21.7b were both upregulated dramatically by heat and cold, and Cshsp21.5 could be induced by cold stress. Neither Cshsp21.4 nor Cshsp21.7a responded to heat or cold. These results demonstrated that different Csshsps play distinctive roles in the regulation of the physiological activities in C. suppressalis. © 2013 Cell Stress Society International.

The basic helix–loop–helix (bHLH) transcription factors are one of the largest families of gene regulatory proteins and play crucial roles in genetic, developmental and physiological processes in eukaryotes. Here, we conducted a survey of the Sus scrofa genome and identified 109 putative bHLH transcription factor members belonging to super-groups A, B, C, D, E, and F, respectively, while four members were orphan genes. We identified 6 most significantly enriched KEGG pathways and 116 most significant GO annotation categories. Further comprehensive surveys in human genome and other 12 medical databases identified 72 significantly enriched biological pathways with these 113 pig bHLH transcription factors. From the functional protein association network analysis 93 hub proteins were identified and 55 hub proteins created a tight network or a functional module within their protein families. Especially, there were 20 hub proteins found highly connected in the functional interaction network. The present study deepens our understanding and provided insights into the evolution and functional aspects of animal bHLH proteins and should serve as a solid foundation for further for analyses of specific bHLH transcription factors in the pig and other mammals. © 2015, Springer-Verlag Berlin Heidelberg.

In this paper, we investigate the global exponential stability of fuzzy cellular neural networks with time-varying delays in the leakage terms and reaction-diffusion terms. By constructing a novel Lyapunov functional and applying inequality technique, we obtain some new sufficient conditions for the existence, uniqueness and global exponential stability of the equilibrium solution. Moreover, an numerical example is provided to demonstrate the feasibility of our method. © 2014 Elsevier B.V.
