A method for fast and low bit-rate compression of digital holograms based on a new vector quantization （VQ） method known as the skip-dimension VQ （SDVQ） is proposed. Briefly, a complex hologram is converted into a real off-axis hologram, and partitioned into a set of image vectors. The image vectors are passed into a graphic processing unit （GPU）, and compressed through SDVQ into a set of code indices considerably smaller in data size than the source hologram. Experimental evaluation reveals that our scheme is capable of compressing a digital hologram to a compression ratio of over 500 times, in approximately 20-22 ms.

Missing checks for untrusted inputs used in security-sensitive operations is one of the major causes of various vulnerabilities. Efficiently detecting and repairing missing checks are essential for prognosticating potential vulnerabilities and improving code reliability. we propose a systematic static analysis approach to detect missing checks for manipulable data used in security-sensitive operations of c/c++ programs and recommend repair references. First, customized securitysensitive operations are located by lightweight static analysis. Then, the assailability of sensitive data used in securitysensitive operations is determined via taint analysis. And, the existence and the risk degree of missing checks are assessed. Finally, the repair references for high-risk missing checks are recommended. we implemented the approach into an automated and cross-platform tool named Vanguard based on clang/LLVM 3.6.0. Large-scale experimental evaluation on open-source projects has shown its effectiveness and efficiency. Furthermore, Vanguard has helped us uncover five known vulnerabilities and 12 new bugs.

A series of TiO2 with different crystal phases and morphologies was synthesized via a facile hydrothermal process using titanium nbutoxide and concentrated hydrochloric acid as raw materials. The photocatalytic activity of the samples was evaluated by degradation of Methyl Orange in aqueous solution under UV-Visible light irradiation. On the basis of detailed analysis of the characterizing results of high-resolution transmission electron microscopy, X-ray powder diffraction measurements, X-ray photoelectron spectroscopy and Brunauer-Emmett-Teller measurement, it was concluded that the photo-activity of the catalyst is related directly to the 3D morphology and the crystal phase composition. An excellent catalyst should have both a futile 3D flower-like structure and anatase granulous particles. The 3D flower-like structure could enhance light harvesting, as well as the transfer of reactant molecules from bulk solution to the reactive sites on TiO2. In addition, the optimum anatase/rutile phase ratio was found to be 80：20, which is beneficial to the effective separation of the photogenerated electron-hole pairs.

[目的]旨在掌握某工业场地土壤中砷(As)的空间分布特征并揭示其迁移规律,为该工业场地土壤As污染防治提供数据与理论基础。[方法]本文选取葫芦岛市某工业场地为研究区,首先统计分析了场地内土壤As含量的空间分布特征,并比较了等温与动态吸附两种获取土壤中As(Ⅲ)吸附参数的实验方法的特点与适用性,最终利用HYDRUS-1D模型反演计算了As(Ⅲ)在供试土壤中的D_(L)、K、α、β等迁移参数。[结果]场地土壤As浓度水平分布具有显著差异,在垂向上主要富集于40 cm深度内,且随深度增加而降低。等温吸附实验的结果表明:土样中As(Ⅲ)的平衡固相浓度随液相浓度增加呈非线性增长趋势,Langmuir模型(R^(2)=0.988)对实测数据的拟合效果优于Henry和Freundlich模型。动态吸附实验结果展示了As(Ⅲ)相对浓度完全穿透土柱所需的污染液体积随As(Ⅲ)初始浓度的增加而减少的规律;HYDRUS-1D反演结果表明三类吸附模型中,Langmuir模型(R^(2)=0.990)更适用于模拟土样中As(Ⅲ)的动态吸附过程。相较于等温吸附实验,使用动态吸附实验模拟As(Ⅲ)迁移行为更接近其在土壤中的真实迁移过程。[结论]该场地中的As污染来源于工业活动,主要集中在浅层土壤;土壤中As(Ⅲ)的迁移行为表现为非线性过程,较高的初始浓度将加速As(Ⅲ)的垂向迁移。动态吸附实验方法应优先应用于土壤As迁移过程及其参数获取的研究中。

The novel epoxidized soybean oil-modified-phenolic resin/clay nanocomposites（ESO-M-PR/ cN） was prepared. The coupling agent-benzyldimethylphenylammonium chloride [c6H5cH2N^＋（cH3）2c6H5cl^- , B2MP] was adopted to modify the interface between the organic and inorganic phases. The effect of the nanocomposite structure on its physical and chemical properties was discussed. During the synthesizing process of ESO-M-PR/cN, the phenol hydroxyl was etherified by ESO or ESO epoxy resin prepolymer to provide long ESO epoxy segments. Long ESO epoxy resin chain segments enhanced the crosslink density of ESO-M- PR/cN. The thermal and mechanical properties exhibit a significant improvement. The temperature at which a weight loss of 5% occurs increases from 287.1 ℃ to 402.3 ℃. The flexural strength increases by 25%, while the flexural modulus increases by 39%. Moreover, the properties of resin were enhanced by the effect of the inorganic nanoparticles, while the size of the nanomontmorillonites in the phenolic resin was characterized with a scanning electron microscope. The particle size of inorganic montmorillonites in the modified system is less than 100 nm.
