The accuracy of land surface hydrological simulations using an offline land surface model(LSM)depends largely on the quality of the atmospheric forcing *** this study,Global Land Data Assimilation System(GLDAS)forcing data and the newly developed China Meteorological Administration Land Data Assimilation System(CLDAS)forcing data are used to drive the Noah LSM with multiple parameterizations(Noah-MP)and to explore how the newly developed CLDAS forcing data improve land surface hydrological simulations over China's *** monthly soil moisture(SM)and evapotranspiration(ET)simulations are then compared and evaluated against *** results show that the Noah-MP driven by the CLDAS forcing data(referred to as CLDASNoah-MP)significantly improves the simulations in most cases over China's Mainland and its eight river *** increases the correlation coefficient(R)values from 0.451 to 0.534 for the SM simulations at a depth range of 0–10 cm in China's Mainland,especially in the eastern monsoon area such as the Huang–Huai–Hai Plain,the southern yangtze River basin,and the Zhujiang River ***,the root-mean-square error is reduced from 0.078 to0.068 m3 m-3 for the SM simulations,and from 12.9 to 11.4 mm month-1 for the ET simulations over China's Mainland,especially in the southern yangtze River basin and Zhujiang River *** study demonstrates that,by merging more in situ and remote sensing observations in regional atmospheric forcing data,offline LSM simulations can better simulate regional-scale land surface hydrological processes.

Understanding of metal oxidation is very critical to corrosion control,catalysis synthesis,and advanced materials *** oxidation is a very complex phenomenon,with many different processes which are coupled and involved from the onset of *** this work,the initial stage of oxidation on titanium surface was investigated in atomic scale by molecular dynamics(MD)simulations using a reactive force field(ReaxFF).We show that oxygen transport is the dominant process during the initial *** simulation also demonstrate that a compressive stress was generated in the oxide layer which blocked the oxygen transport perpendicular to the Titanium(0001)surface and further prevented oxidation in the deeper *** mechanism of initial oxidation observed in this work can be also applicable to other self-limiting oxidation.

锂（Li）盐作为一种精神科药物常被用于治疗重性抑郁障碍，然而长期服用Li盐会产生高中毒风险，及时监测患者血液中Li元素的浓度，对确保用药安全和临床治疗效果非常重要。激光诱导击穿光谱（Laser-induced breakdown spectroscopy, LIBS）作为一种快速分析技术，被广泛应用于实际场景下复杂基质的元素分析。本研究采用LIBS技术结合偏最小二乘法（Partial least squares, PLS）对血液基质中的Li元素进行定量分析。采用45组临床血液样品，分别构建血浆和全血基质下Li元素的定量分析模型，通过五折交叉验证方法对PLS算法中的潜变量数进行优化。结果表明，基于血浆基质构建的PLS定量分析模型预测决定系数（R2）为0.992，预测均方根误差（RMSEP）为0.204μg/mL，相对标准偏差（RSD）为2.14%；基于全血基质构建的PLS定量分析模型R2为0.984, RMSEP为0.728μg/mL, RSD为3.45%，因此，基于血浆定标值所建立的LIBS模型定量分析全血中锂元素的效果更佳。LIBS技术为临床血锂的快速检测评估提供了一种新的选择，具有良好的应用前景。

Electrochemical Study on the Interaction of Protein with Bromothymol Blue and Its Analytical Application

引用

Chemical Research in Chinese Universities 2008年第6期24卷 701-706页

作者： WANG Xue-liang yang Jie JIAO Kui College of Chemistry and Molecular Engineering Qingdao University of Science and Technology Qingdao 266042 P. R. China

The interaction of bromothymol blue（BB） with human serum albumin（HSA） was studied by electrochemical techniques and a sensitive method for proteins assay was developed. When BB interacted with HSA, the voltammetric peak current value of BB decreased linearly with the concentration of HSA in a range of 1.0--40.0 mg/L, and the peak potential shifted negatively. Based on the results, a sensitive assay method for proteins, such as HSA, bovine serum albumin（BSA）, and egg albumin etc. was established. This method was further applied to determining the HSA in healthy human blood samples, and the results are not significantly different from those obtained by the classic Coomassie Brilliant Blue G-250 spectrophotometic method. The detecting conditions of this method were optimized and the interaction mechanism was discussed. The results show that the electrochemical parameters（formal potential E^0, standard rate constant of the electrode reaction ks, parameter of kinetic nα） of BB have no obvious changes before and after the interaction, which indicate that BB can interact with HSA, forming an electrochemical non-active complex. The equilibrium constant（βs） and the binding ratio（m） for this complex were calculated. The m is 4 and βs is 1.41 × 10^19. This method is fast, simple, highly sensitive, and has good selectivity, which can be used in clinical measurements.

With the number of connected devices increasing rapidly,the access latency issue increases drastically in the edge cloud *** low time-constrained and data-intensive mobile applications require efficient replication strategies to decrease retrieval ***,the determination of replicas is not reasonable in many previous works,which incurs high response *** this end,a correlation-aware replica prefetching(CRP)strategy based on the file correlation principle is proposed,which can prefetch the files with high access *** key is to determine and obtain the implicit high-value files effectively,which has a significant impact on the performance of *** achieve the goal of accelerating the acquisition of implicit highvalue files,an access rule management method based on consistent hashing is proposed,and then the storage and query mechanisms for access rules based on adjacency list storage structure are further *** theoretical analysis and simulation results corroborate that CRP shortens average response time over 4.8%,improves average hit ratio over 4.2%,reduces transmitting data amount over 8.3%,and maintains replication frequency at a reasonable level when compared to other schemes.
