DNA barcoding is an increasingly prevalent molecular biological technology which uses a short and conserved DNA fragment to facilitate rapid and accurate species identification. Kalidium species are distributed in saline soil habitat throughout Southeast Europe and Northwest Asia, and used mainly as forage grass in China. The discrimination of Ka-lidium species was based only on morphology-based identification systems and limited to recognized species. Here, we tested four DNA candidate loci, one nuclear locus （ITS, internal transcribed spacer） and three plastid loci （rbcL9 matK and ycflb）, to select potential DNA barcodes for identifying different Kalidium species. Results showed that the best DNA barcode was ITS locus, which displayed the highest species discrimination rate （100%）, followed by matK （33.3%）,ycflb （16.7%）, and rbcL （16.7%）. Meanwhile, four loci clearly identified the variant species, Kalidium cuspidatum （Ung.-Stemb.） ***.A. J. Li,as a single species in Kalidium.

With the regarding to the demand that the parameters vary rapidly over a wide range for the highly maneuverable technology（Hi MAT） vehicle, a switched linear model with the locally overlapped characteristic is established for a full-envelope flight. Based on the mode-dependent average dwell time（MDADT） method, a stability criterion for the above switched linear model is proposed, and an application to a full-envelope flight controller is designed, which shows fewer restrictions than that of the average dwell time（ADT）. Furthermore, a numerical simulation is given to prove the correctness and feasibility of this method.

In order to understand the global health related information rapidly and timely, a global health information platform based on big data from internet is constructed. In this paper, we introduce the framework and application of the global health information platform. The functions of information platform mainly include two aspects： to analyze and disseminate theoretical and technological progress of the main research fields in global health and to monitor real-time emergencies, epidemic situation and hot topics related to the field of global health. The objective of this research is to establish a Chinese-English bilingual information platform in the global health field. The platform would help academic researchers understand and master global health progress in time; acquire information of global health comprehensively, accurately and dynamically; and eventually help deal with the risk of global diseases, formulate appropriate health policies and actively participate in the international global health affairs.

Mobile device is an important interactive platform. Due to the limitation of computation, memory, display area and energy, how to realize the efficient and real-time interaction of 3D models based on mobile devices is an important research topic. Considering features of mobile devices, this paper adopts remote rendering mode and point models, and then, proposes a transmission and rendering approach that could interact in real time. First, improved simplification algorithm based on MLS and display resolution of mobile devices is proposed. Then, a hierarchy selection of point models and a QoS transmission control strategy are given based on interest area of operator, interest degree of object in the virtual environment and rendering error. They can save the energy consumption. Finally, the rendering and interaction of point models are completed on mobile devices. The experiments show that our method is efficient.

Background Determining how an image is visually appealing is a complicated and subjective task. This motivates the use of a machine-learning model to evaluate image aesthetics automatically by matching the aesthetics of the general public. Although deep learning methods have successfully learned good visual features from images,correctly assessing the aesthetic quality of an image remains a challenge for deep learning. Methods To address this, we propose a novel multiview convolutional neural network to assess image aesthetics assessment through color composition and space formation(IAACS). Specifically, from different views of an image––including its key color components and their contributions, the image space formation, and the image itself––our network extracts the corresponding features through our proposed feature extraction module(FET) and the Image Net weight-based classification model. Result By fusing the extracted features, our network produces an accurate prediction score distribution for image aesthetics. The experimental results show that we have achieved superior performance.
