3Temperature effect and thermal impact in lithium-ion batteries: A review显示文摘Lithium-ion batteries, with high energy density(up to 705 Wh/L) and power density(up to 10,000 W/L), exhibit high capacity and great working performance. As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects. Accurate measurement of temperature inside lithiumion batteries and understanding the temperature effects are important for the proper battery management. In this review, we discuss the effects of temperature to lithium-ion batteries at both low and high temperature ranges.The current approaches in monitoring the internal temperature of lithium-ion batteries via both contact and contactless processes are also discussed in the review.Shuai Ma Modi Jiang Peng Tao Chengyi Song Jianbo Wu Jun Wang Tao Deng Wen Shang 2018Progress in Natural Science:Materials International2018,28,6:27
4Report on Childhood Obesity in China (9): Sugar-sweetened Beverages Consumption and Obesity显示文摘Objective To explore the associations between sugar-sweetened beverage (SSB) consumption and obesity as well as obesity-related cardiometabolic disorders among children in China. Methods A total of 6974 (boys 3558, girls 3412) children aged 6-13 years participated in the study. Each participant's height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio (95% confidence internal (CI)] of obesity was 7.6% [as the reference group (ref.)], 10.1% [1.36(1.07, 1.74)], and 11.6% [1.46(1.21, 1.75)], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio (95% CI): 1.36 (1.17, 1.59)]. The prevalence [adjusted odds ratio (95% CI)] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00(1.31, 3.07)], 12.7% [1.52(1.23, 1.88)], 11.5% [1.52(1.18, 1.95)], and 10.4% [1.41(1.03, 1.94)], respectively, which was higher than that of regular milk drinkers [7.6 % (ref.)]. The prevalence [adjusted odds ratio (95% CI)] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55(1.26, 1.90)], 16.2% [1.36(1.09, 1.70)], and 15.3% [1.24(1.03, 1.50)], respectively, which was much higher than that of regular milk drinkers [12.8% (ref.)]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design.SHANG Xian Wen LIU Ai Ling ZHANG Qian HU Xiao Qi DU Song Ming MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin LI Ting Yu MA Guan Sheng 2012Biomedical and Environmental Sciences2012,25,2:23

16Diagnostic value of gadobenate dimeglumine-enhanced hepatocyte-phase magnetic resonance imaging in evaluating hepatic fibrosis and hepatitis显示文摘AIM To evaluate the diagnostic value of gadobenate dimeglumine(Gd-BOPTA)-enhanced hepatocyte-phase magnetic resonance imaging(MRI) in evaluating hepatic fibrosis and hepatitis.METHODS Hepatocyte-phase images of Gd-BOPTA-enhanced MRI were retrospectively evaluated in 76 patients with chronic liver disease. These patients were classified into five groups according to either the histopathological fibrosis stage(S0-S4) or the histopathological hepatitis grade(G0-G4). The relative enhancement ratio(RE) of the liver parenchyma in the T1-vibe sequence was calculated by measuring the signal intensity before(SI pre) and 90 min after(SI post) intravenous injection of Gd-BOPTA using the following formula: RE =(SI post-SI pre)/SI pre. One-way analysis of variance was used to compare the difference between the relative RE in the hepatocyte phase(REh) and the stage of hepatic fibrosis and the grade of hepatitis. Pearson's productmoment correlation analysis was used to evaluate the relationship between the REh and the levels of serologic liver functional parameters.RESULTS According to histopathological hepatic fibrosis stage, the 76 patients were classified into five groups: 16 in S0, 15 in S1, 21 in S2, 9 in S3, and 15 in S4 group. According to histopathological hepatitis grade, the 76 patients were also classified into five groups: 0 in G0, 44 in G1, 22 in G2, 8 in G3, and 2 in G3 group. With regard to the stage of hepatic fibrosis, REh showed significant differences between the S2 and S3 groups and between the S2 and S4 groups(P < 0.05), but no significant difference was observed between the other groups. With regard to the grade of hepatitis, REh showed significant differences between the G1 and G2 groups and between the G1 and G4 groups(P < 0.05), but no significant difference was observed between the other groups. Increased REh showed correlations with decreased serum levels of TB, ALT and AST(P < 0.05). CONCLUSION To some extent, measuring the REh using Gd-BOPTAenhanced MRI might be a noninvasive technique for assessing the stage of hepatic fibrosis. This method is able to differentiate no/mild hepatitis from advanced hepatitis. TB, ALT and AST levels can predict the degree of liver enhancement in the hepatocyte phase of Gd-BOPTA-enhanced MRI.Xiu-Mei Li Zhu Chen En-Hua Xiao Quan-Liang Shang Cong Ma 2017World Journal of Gastroenterology2017,23,17:10
17Relationship Between Lodging Resistance and Chemical Contents in Culms and Sheaths of Japonica Rice During Grain Filling显示文摘To understand the relationship between lodging resistance and chemical component contents in culms and leaf sheaths of rice,the physical strength and maximum bearing capacity of culm,and the contents and amounts of potassium(K),silicon(Si)and soluble sugars in culms and leaf sheaths were investigated using four japonica rice varieties with different lodging resistance characteristics during grain filling.There were significant differences in the total amounts of K,Si and soluble sugars in culms and leaf sheaths among the tested rice varieties.The difference in the total amount of Si was greater than that of K or soluble sugars.The physical strength and maximum bearing capacity of culm continuously decreased from heading to ripening,with a rapid decrease at the dough stage.However,the contents and total amounts of K and Si in culms and the Si content in leaf sheaths gradually increased and an accumulation of K and Si in culms was exhibited,whereas the content and total amount of K and the total amount of Si in leaf sheaths gradually decreased and an exportation of K and Si in leaf sheaths was presented.The physical strength was positively and significantly correlated with the total amounts of K and Si in culms during grain filling except that at the heading stage,the total amount of soluble sugars in culms at the heading and milky stages,the total amounts of Si and soluble sugars in leaf sheaths at the heading stage,the total amount of K in leaf sheaths at the heading and milky stages,and the maximum bearing capacity during grain filling.It is suggested that the lodging resistance of japonica rice would be improved by increasing the amount of soluble sugars in plants at the early filling stage,and enhancing the amount of Si in plants during grain filling through topdressing Si fertilizer at the early filling stage.ZHANG Feng-zhuan JIN Zheng-xun MA Guo-hui SHANG Wen-nan LIU Hai-ying Xu Mei-lan LIU Yan 2010Rice science2010,17,4:8

19An efficient RNS parity checker for moduli set{2~n-1,2~n+1,2^(2n)+1}and its applications显示文摘Residue number system (RNS) has received considerable attention since decades before,because it has inherent carry-free and parallel properties in addition,sub-traction,and multiplication operations. For an odd moduli set,the fundamental problems in RNS,such as number comparison,sign determination,and overflow detection,can be solved based on parity checking. The paper proposes a parity checking algorithm along with related propositions and the certification based on the celebrated Chinese remainder theory (CRT) and mixed radix conversion (MRC) for the moduli set {2n-1,2n+1,22n+1}. The parity checker consists of two modular adders and a carry-look-ahead chain. The hardware implementation requires less area and path delay. Besides,the implementations of number comparison,sign determination,and overflow detection,which are based on this parity checker,are also performed in this paper. And this kind of parity checker can be used as a basic element to design ALUs and DSP module in RNS.MA Shang HU JianHao ZHANG Lin LING Xiang 2008Science in China(Series F)2008,51,10:8
20Relationship between composite structures and compressive properties in CuZr-based bulk metallic glass system显示文摘Bulk metallic glass (BMG) composites with the austenite B2 phase as reinforcement macroscopically showed strain hardening behavior due to the plasticity induced by martensitic transformation during deformation. Relationship between characteristics of the B2-CuZr reinforcing phase and uniaxial compressive properties of CuZr-based BMG composites was studied. Mechanical properties of these BMG composites were found to depend on not only the reinforced phases but also the amorphous matrix,and the yield and fracture strength can be roughly estimated by the rule of mixture principle. Distribution of the reinforced B2-CuZr phase has an important impact on the compressive plasticity even for the composites with a similar volume fraction of the crystalline phase.WU Yuan SONG WenLi ZHANG ZhongYan HUI XiDong MA Dong WANG XunLi SHANG XinCun LU ZhaoPing 2011Chinese Science Bulletin2011,56,36:8
