A study focus on the New Media Information Service Product(NMISP) application in university is presented in this paper. With randomly selected 200 students, a self-compiled questionnaire of [Satisfaction of NMISP in university] is carried out for investigating the tendency of NMISP, and finding the uniqueness of user experience, which helps to point out the characteristics of NMISP in campus use, compared with urban public information products. Based on the questionnaire analysis, the proposal of NMISP design suitable for the modern university students' use experience, and the suggestion of overall layout are presented in this paper. © 2017 IEEE.

A growing body of evidence suggests that inflammation may contribute toward the development of major depressive disorder. Mangiferin, a glucosylxanthone from Mangifera indica, exerts a number of biological actions, including anti-inflammatory effects. Although mangiferin has potential antidepressant activity, the mechanisms of this effect remain unclear. The present study investigated the effects of mangiferin on behavioral changes and inflammatory responses induced by chronic mild stress (CMS) in mice. We found that treatment with mangiferin for 3 weeks significantly increased the body weight of mice and ameliorated CMS-induced behavioral abnormalities by increasing sucrose consumption, improving locomotor activities, and decreasing the immobility time in the forced-swimming test and tail-suspension test. It also suppressed increased serum corticosterone levels in CMS mice. In response to CMS induction, the NLRP3 inflammasome was activated and interleukin (IL)-1β and IL-18 levels were increased in the mouse hippocampus. Mangiferin treatment downregulated the expression of NLRP3, ASC, and caspase-1, which subsequently reduced the production of IL-1β and IL-18 in CMS mice. In sum, our results indicate that mangiferin exerts antidepressant-like effects in CMS model, possibly by inhibiting IL-1β production and NLRP3 inflammasome expression.

The conversion of high-mode solitons propagating in Strongly Nonlocal Nonlinear Media (SNNM) in three coordinate systems, namely, the elliptic coordinate system, the rectangular coordinate system and the cylindrical coordinate system, based on the Snyder–Mitchell Model that describes the paraxial beam propagating in SNNM, is discussed. Through constituting the trial solution with modulating the Gaussian beam by Ince polynomials, the closed-solution of Gaussian beams in elliptic coordinate is accessed. The Ince–Gaussian (IG) beams constitute the exact and continuous transition modes between Hermite–Gaussian beams and Laguerre–Gaussian (LG) beams, which is controlled by the elliptic parameter. The conditions of conversion in the three types of solitons are given in relation to the Gouy phase invariability in stable propagation. The profiles of the IG breather at a different propagating distance are numerically obtained, and the conversions of a few IG solitons are illustrated. The difference between the IG soliton and the corresponding LG soliton is remarkable from the Poynting vector and phase plots at their profiles along the propagating axis. © 2016 Informa UK Limited, trading as Taylor & Francis Group.

We have analytically and numerically investigated the propagation of three-dimensional self-decelerating Airy-Elegant-Laguerre-Gaussian (AiELG) wave packets by solving the (3+1)D free-space Schrödinger equation. We found that their intensity profiles are determined by three parameters: the azimuthal mode number, the radial mode number and the modulation depth. The modulation depth has effect on the azimuthal mode number. If the modulation depth equals to 1, the azimuthal mode number cannot take affect. The beam dose not split along the angular orientation. The self-decelerating AiELG wave packet shows ring. Otherwise, the modulation depth equals to 0, azimuthal mode number will take affect, and the self-decelerating AiELG wave packet shows necklace. It is worth mentioning that the radial mode number of self-decelerating AiELG wave packet will change in propagation. The reason is that the direction of the energy flow is always kept away from the centre during propagation. © 2017 Informa UK Limited, trading as Taylor & Francis Group

Nanostructure-based photovoltaic devices have exhibited several advantages, such as reduced reflection, extraordinary light trapping, and so forth. In particular, semiconductor nanostructures provide optical modes that have strong dependence on the size and geometry. Metallic nanostructures also attract a lot of attention because of the appealing plasmonic effect on the near-field enhancement. In this study, we propose a novel design, the metal-core/ semiconductor-shell nanocones with the core radius varying in a linearly gradient style. With a thin layer of semiconductor absorber coated on a metallic cone, such a design can lead to significant and broadband absorption enhancement across the entire visible and near-infrared solar spectrum. As an example of demonstration, a layer of 16 nm thick crystalline silicon (c-Si) coated on a silver nanocone can absorb 27% of standard solar radiation across a broad spectral range of 300-1100 nm, which is equivalent to a 700 nm thick flat c-Si film. Therefore, the absorption enhancement factor approaching the Yablonovitch limit is achieved with this design. The significant absorption enhancement can be ascribed to three types of optical modes, that is, Fabry-Perot modes, plasmonic modes, and hybrid modes that combine the features of the previous two. In addition, the unique nanocone geometry enables the linearly gradient radius of the semiconductor shell, which can support multiple optical resonances, critical for the broadband absorption. Our design may find general usage as elements for the low cost, high efficiency solar conversion and water-splitting devices. © 2014 American Chemical Society.

The porous Fe3O4/C microbelts (FCBs) were synthesized by simple electrospinning method, combined with carbonization of the precursor microbelts at high temperature in N2 flow. Compared with α-Fe2O3 microbelt, the FCBs show better cyclic performance. The high capacity of 710 mA h g-1 is still maintained after 50 cycles. The excellent performance of FCBs in lithium-ion batteries can be attributed to the highly stable porous belt structure of FCBs and to the substantial structure carbon matrix surrounded Fe3O4 nanoparticles. The synthesis method is simple, cheap, and green and could be extended to fabricate other carbon composites. © 2013 American Chemical Society.

A 4d-4f heterometallic coordination polymer, [AgNd(pydc) 2]·2H 2O (1) (H 2pydc=pyridine-3,4- dicarboxylic acid), was synthesized under hydrothermal conditions, and further characterized by elemental analysis, IR, thermogravimetric analysis and single-crystal X-ray diffraction. Complex 1 featured a three-dimensional (3D) framework containing one-dimensional (1D) channels occupied by free water molecules, which was constructed from 1D inorganic heterometallic chains and linear pydc linkers. To our knowledge, complex 1 represented a rare example of 3D open-framework 4d-4f heterometallic coordination polymer. After removal of the water molecules from complex 1, the remaining material had high thermal stability. Moreover, the near-infrared luminescent properties of 1 were also investigated in the solid state. © 2012 The Chinese Society of Rare Earths.

We present a "master-slave-response" synchronization system of chaotic multiple-quantum-well lasers. And we study the applications of chaotic parallel synchronization for optical logic gates. An injection multiple-quantum-well laser drives two responding systems of multiple-quantum-well lasers to obtain chaotic synchronization while the injection multiple-quantum-well laser can synchronize the responding systems. We present theoretically the constructions of the fundamental all-optical gates based on the parallel synchronization of responding systems and define their computational principle. By modulating the driving light into the responding systems, all-optical logic gates characterizing logic function are realized by synchronizing or unsynchronizing appropriately the two chaotic states of responding systems. We present all-optical XNOR, NOR, NOT logic gates and their logic computational methods. Numerical simulation result validates the feasibility of the system. © 2013 Chinese Physical Society.

Based on the Snyder-Mitchell model that describes the paraxial beam propagating in strongly nonlocal nonlinear media and the trial solution with modulating the Gaussian beam by the parabolic cylinder functions, the close forms of elegant Hermite-Gaussian beams (EHGB) are accessed in Cartesian coordinate system. The collinear EHGB will evolve to be the rotating charge vortex EHGB on certain condition. It is shown that the transferring of the single EHGB and the rotating charge vortex EHGB at the critical power. The widths of the profiles of the breathers and the rotating charge vortex breathers are varied periodically in the transferring.
