Nowadays,distance is usually used to evaluate the error of trajectory *** methods can effectively indicate the level of geometric similarity between the compressed and the raw trajectory,but it ignores the velocity error in the *** fill the gap of these methods,assuming the velocity changes linearly,a mathematical model called SVE(Time Synchronized Velocity Error)for evaluating compression error is designed,which can evaluate the velocity error effectively,conveniently and *** on this model,an innovative algorithm called SW-MSVE(Minimum Time Synchronized Velocity Error Based on Sliding Window)is proposed,which can minimize the velocity error in trajectory compression under the premise of local *** elaborate experiments are designed to demonstrate the advancements of the SVE and the SW-MSVE *** the first experiment,we use the PED,the SED and the SVE to evaluate the error under four compression algorithms,one of which is the SW-MSVE *** results show that the SVE is less influenced by noise with stronger performance and more *** the second experiment,by marking the raw trajectory,we compare the SW-MSVE algorithm with three others algorithms at information *** results show that the SW-MSVE algorithm can take into account both velocity and geometric structure constraints and retains more information of the raw trajectory at the same compression ratio.

Large area uniform plasma sources,such as high-density magnetized inductively coupled plasma(ICP)and helicon plasma,have broad applications in industry.A comprehensive comparison of ICP and helicon plasma,excited by a single-loop antenna,is presented in this paper from the perspectives of mode transition,hysteresis behavior,and density *** E-H mode transition in ICP and the E-H-W mode transition in helicon plasma are clearly observed in the ***,the considerable variation of hysteresis behavior from inverse hysteresis to normal hysteresis by the influence of the magnetic field is *** bi-Maxwellian and Maxwellian electron energy distribution functions in each discharge are used to explain this phenomenon,which is essentially related to the transition from a nonlocal kinetic property to a local kinetic property of *** addition,we notice that the plasma density,in the radial direction,is peaked in the center of the tube in ICP,but a complicated distribution is formed in helicon *** the axial direction,the maximum plasma density is still in the center of the antenna in ICP,whereas the highest plasma density is located downstream,far away from the antenna,in helicon *** is believed that the reflected electrons in the sheath and pre-sheath by the upper metallic endplate and downstream propagated helicon wave will be responsible for this plasma density profile in helicon *** to the constrained electron motion in the magnetic field,an extremely uniform density distribution will be obtained with an appropriate axial magnetic field in the wave discharge mode.

Graphene is the most attractive carbon-based material at present and attracting increasing attention as promising candidates for applications in numerous areas, because of its extraordinary chemical, thermal and mechanical properties. In this paper, we discussed an innovative and simple method to synthesize titanium dioxide （TiO2） nanoclusters, using graphene as a mid-step template not as a component of final product. Using this method, the graphene was firstly fully coated with TiO2 nanoparticles by the thermal decomposition of titanium （IV） isopropoxide in a supercritical carbon dioxide （SC-CO2） at 200 ℃; the developed TiO2/graphene composites then were heated in an oxygen atmosphere. Eventually the TiO2 nanoclusters were obtained. The prepared TiO2 nanoclusters showed irregular features with high surface coverage, providing promises in a wide range of applications, especially for photo-degradation of organic compounds in aqueous solution under the radiation of UV-light.

Dear Editor ：The sustainable cultivation of rice, which serves as staple food crop for more than half of the world＇s population, is under serious threat due to the huge yield losses inflicted by rice blast disease caused by the globally destructive fungus Magnaporthe oryzae （Pyricularia oryzae）（Dean et al., 2012; Nalley et al., 2016; Deng et al., 2017）. This filamentous ascomycete fungus is also capable of causing blast infection on other economically important cereal crops, including wheat, millet, and barley, making it the world＇s most important plant pathogenic fungus （Zhong et al., 2016）.
