2016 International Conference on Electrical Engineering and Automation（ICEEA2016）

作者： Yun-fei ZHENG Xiong-wei ZHANG Tie-yong CAO Yong-gang HU PLA University of Science and Technology The Officer Academy of Army The Key Laboratory of Polarization Imaging Detection Technology

Due to the lack of object semantic information, existing salient region detection models using visual stimulus cues and prior knowledge are diffcult to detect some complicated salient regions with heterogeneity, low contrast or large scale. We construct a semantic salient region detection network using the fully convolutional structure in this letter. After training effectively, the proposed network can effectively extract the semantic salient regions. Aiming to the defect of inaccurate boundary of the detected semantic salient regions, we further introduce the superpixel segmentation and color appearance model to generate the superpixel-level foreground ***, we propose a new optimization model to fuse the foreground and background probability information and semantic information to derive more accurate salient region map. The experiments comparing with 11 state-of-the-art models demonstrate the effectiveness and robustness of the proposed model.

Yolk-Shell Nanostructure: An Ideal Architecture to Achieve Harmonious Integration of Magnetic-Plasmonic Hybrid Theranostic Platform

Magnetic-plasmonic hybrid nanoparticles (MPHNs) have attracted great interest in cancer theranostics. However, the relaxivity of the magnetic component is typically reduced by the plasmonic component in conventional core-shell structured MPHNs, due to the presence of a water-impenetrable coating which severely restricts the proximity of protons to the magnetic portion. To circumvent this issue, yolk-shell structured MPHNs comprising a Fe O core within a hollow cavity encircled by a porous Au outer shell are designed. As expected, the introduction of hollow cavity between the magnetic and plasmonic portions significantly prevents the decline in relaxivity of the Fe O core caused by the Au layer. Moreover, in addition to conferring high near-infrared absorption to plasmonic component, the hollow cavity and the pores in the outer shell can also provide a large storage space and release channels for anticancer drugs. Furthermore, the multicomponent nanoparticles (NPs) still have a compact size of less than 100 nm to ensure efficient tumor accumulation. Taken together, the yolk-shell Fe O @Au NPs can be regarded as an ideal magnetic-plasmonic theranostic platform for magnetic resonance/photoacoustic/positron emission tomography multimodal imaging and light-activated chemothermal synergistic therapy.

Meteorological satellites have become an irreplaceable weather and ocean observing tool. Since the first Chinese polar-orbiting meteorological satellite Feng-Yun (FY-1A) was launched successfully in 1988, there are totally 13 meteorological satellites that were launched into both sun synchronous and geostationary orbit. China is among the few countries in the world which are simultaneously operating both orbiting meteorological satellites. All the satellites have been incorporated into the global constellations of operational meteorological satellites within the WMO framework. More satellites are under construction to be the second generation ones. The status of Chinese meteorological satellite mission is introduced in this paper.

A fully integrated buck converter with a novel digital soft-start circuit

A novel digital soft-start circuit in the fully integrated buck converter is presented in this paper. The soft-start approach based on a linearly ramped-up reference is proposed to prevent massive in-rush current and overshoot voltage during the start-up phase of the buck converter. Compared with conventional soft-start circuit, the novel circuit is realized by a compact on-chip circuit that requires no external pins and is very simple as well. A fully integrated DC–DC buck converter with proposed circuit has been based on a 0.18 μm mixed signal CMOS process. The results show that this novel soft-start enables the output voltage of the converter to be linearly ramped up to the steady state. © 2015 Engineers Australia.

Dear Editors, Terahertz technology has been applied in many fields [1-3]. The protection and restoration of historical relics and cul- tural heritage, which is a new application area of terahertz technology, have been attracting much attention recently [4,5] because of its social significance and market prospects The most important premise is to obtain information of the cultural relics without damaging them again. Therefore the appropriate non-destructively testing methods are urgently needed in this area. Terahertz （THz） wave bridges the gap between microwave and infrared waves.
