The authors propose a practical and accurate cross site script prevention method based on delimiters for UTF-8 encoded web applications. Only trusted delimiters are tainted into corresponding UTF-8 shadow bytes, and these tainted shadow bytes are automatically propagated in web applications and can be directly delivered into output pages. Cross site script is prevented by analyzing the tainted delimiters and HTML context of output pages. A prototype called XSSCleaner is implemented on PHP. The evaluation shows that XSSCleaner can accurately protect web applications from real world cross site script attacks with an average overhead 12.9%.

The Qingcaoshan granitic pluton, located in the Zhapu-Duobuza magmatic arc in southern Qiangtang, consists of granite porphyry and quartz monzonitic porphyry. However, the age and genesis are not studied due to absence of geochemical and geochronological data. The weighted average 206Pb/238U age of 122±1 Ma (MSWD=3.9) for quartz monzonitic porphyry and 114.6±1.2 Ma (MSWD=1.1) for granite porphyry is present by LA-ICPMS and SHRIMP zircon U-Pb dating. The intrusion have minor muscovite and cordierite, no hornblende. The granitic pluton is characterized by enriched Al (A1₂O₃: 14.81%-15.86%), depleted Ca (CaO: 1.10%-2.44%), and high content of alkali (K₂O+Na₂O: 6.86%-8.80%). Father more, it is also characterized by ASI of 1.1 (A/CNK: 1.06-1.20), corundum (1.20%-2.86%) and absence of diopside showed through CIPW calculation, which are indicative of peraluminous sub-alkaline S-type graniten. The intrusive rock is relatively enriched in large ion lithophile elements (Rb, Th, U, K, La, Ce) and depleted in high field strength elements (Ta, Nb, P, Ti, Y), and exhibits LREE-enriched ((La/Yb)N: 3.24-16.20) with right-inclined REE distribution patterns. A synthesis of all these characteristics indicates that the Qingcaoshan granitic pluton was probably derived from partial melting of greywacke components in the upper crust as a result of norward subduction of the Bangong Co-Nujiang oceanic crust towards the Qiangtang block.

In order to study the initiate mechanism of pulse detonation engine ignited by low temperature plasma through numerical simulation method, the low temperature plasma ignition discharge area was simplified into heat kernel with high temperature and high pressure considering the propane/air chemical reaction kinetics mechanism. The laminar finite-rate model in the FLUENT was used to simulate the combustion process from deflagration to detonation transition (DDT) initiated by low temperature plasma, and the process was analyzed minutely. The experimental results show that it is feasible to simplify the low temperature plasma ignition to the fire kernel of a certain pressure and temperature in numerical simulation under a reasonable boundary condition that the pressure is atmospheric pressure and the wall temperature is normal temperature. The ignition delay and measurement error results in that the detonation wave development time of the numerical simulation is shorter than that of experimental result. The measurement value of the experiment is close to the result in numerical simulation under the condition of normal pressure heat kernel and normal temperature wall.

The authors review the self-other decision-making differences, and propose that such differences are derived from decision makers’ cognitive differences in construal level. The mental construals are low when people make decisions for themselves, whereas the mental construals are high when they decide for others. Theoretically, self-other decision-making differences are illustrations of bounded rationality. Practically, understanding such differences as well as their mechanisms helps to achieve optimal decisions.

Isotopic composition of nonmethane hydrocarbons, sampled by Tenax TA adsorption tube and detected by thermal desorption-gas chromatography-isotope ratio mass chromatography was analyzed in the main functional area, Lanzhou. The results show that the average δ¹³C values of transportation related sources is - 28. 7‰, significantly below the value of coal-combustion exhaust( - 24. 1‰) . In summer the average δ¹³C values of atmospheric NMHCs are close to each other( from - 29. 5‰ to - 27.4‰), while in winter the average δC values in Xigu industrial estate(-25.5‰) is larger than that in Panxuanlu(-28.8‰) and Erdianchang(- 31.2‰). The results of source analysis indicate that the atmospheric NMHCs in Panxuanlu are mainly emitted by transportation related sources both in summer and winter; the atmospheric NMHCs in Xigu industrial estate in winter are mainly influenced by coal-combustion exhaust, while in summer n-alkanes and benzene are mainly from transportation related sources; in winter atmosphere in Erdianchang pentane, hexane and benzene are from transportation related sources; in summer atmosphere in residential area the NMHCs are mainly influenced by transportation related sources and some unknown sources; benzene is mainly emitted by transportation related sources and was detected in every sampling site both in winter and summer. To reduce the pollution of NMHCs, it is important to control transportation related sources.

The Daqing River is the most seriously polluted river in the Dianchi Lake watershed. A bypass demonstration work of step-feeding biological contact oxidation process ( SBCOP), with the treatment scale of 1000 m³day and the hydraulic retention time (HRT) of 4.75 hours, was built aroundthe river bank to purify the river water. During the winter dry seasonfrom Nov. 2007 to Mar. 2008, three sets of parameters of the demonstration work were operated by regulating step-feeding ratio and air-water rate according to the influent qualities and climatic conditions. The results show that the SBCOP demonstration work kept good removal efficiencies for COD and NH⁺₄ - N, and the averager emoval rates were 37.3% and 32.9% each. The step-feeding ratio of 1∶1∶1 was beneficial for removing COD and NH⁺₄ - N. The removal rate of NH⁺₄ - N decreased when the concentration of NH⁺₄ - N increased. The average removal rate of TN was as lowas 10.5%, owing to the negative impacts of low temperature, carbon source shortage, high DO level of the influent, and loose and porous bio film. Theremoval of TP depended on the deposition of sludge and adsorption of Spirogyra sp., and the average removal rate of TP was 13.7%. To avoid the minus removal rate of TP, sludge discharge and removing of dead Spirogyra sp. were needed. The air-water rate of 2 ∶1 was suitable when influent was Dianchi Lake water.

The authors shows a quantum local theory that can explain the interference experiment which is designed based on the nonlocal double slits experiment. The theoretical results are consistent with the experimental data perfectly.

The authors review current brain imaging (fMRI and PET) studies of semantic representations in bilinguals and point out that the three issues have taken central ground in these studies: (1) whether semantic representations of different languages have identical neural mechanisms? (2) What effects do the proficiency in languages and the age of second language acquisition have on semantic representation in the brain? (3) Which brain areas are responsible for the switching and translation between languages? And whether these areas are devoted exclusively to language switching and/or translation?
