1Effects of Malnutrition on Economic Productivity in China As Estimated by PROFILES显示文摘To calculate the effects of malnutrition on economic productivity in China.Methods PROFILES was used to quantify the function consequences of malnutrition in term of protein energy malnutrition, iron deficiency and iodine deficiency. Results Productivity gained due to improved iodine nutrition. The reduction in the TGR in 1992 to 2001 increased the net present value of further economic productivity by $142 billion. Reduction of the TGR rate to 5% over next 10years would result in future productivity gains with value of $40 billion. Productivity gain due to reductions in child stunting would result in future economic productivity gains with the value of$101billion. Reducing stunting further over the next 10 years would gain $20 billion. Productivity gain due to reduction of iron deficiency anemia reduced by 30% over the next 10 years would gain worth $107billion and if childhood anemia reduced by 30% over next 10 years would gain $348 billion.Conclusion These interventions have huge economic payoff. That is likely to exceed their costs many times over.JAYROSS CHUN-MINGCHEN WuHE GANGFU YU-YINGWANG ZHEN-YINGFU MING-XIACHEN 2003Biomedical and Environmental Sciences2003,16,3:21
2Effects of Malnutrition on Child Survival in China As Estimated by PROFILES显示文摘To estimate the benefits of reductions in underweight and Vitamin A deficiency for child survival in China that might be expected as a result of lowering the prevalence of these conditions. Methods Profiles, a process of nutrition policy analysis was used to quantify the functional consequences of malnutrition in terms of child survival. Results Underweight The actual reduction in underweight between 1992 and 2001 (from 15.7% to the current 10.1 %) resulted in saving of 176 000 child lives. As estimated, without improvements, 612 000 children will die due to underweight between 2001 and 2010, 281 000 (46%) of them living in western provinces. Reducing underweight prevalence from 10.1% to 8% could overall save 62 000 lives. The reduction of underweight prevalence in the west alone might save 56 000 lives. Vitamin A in China as a whole, vitamin A deficiency accounts, as estimated, for 7.5% of deaths of children 6-59 months old, representing 206 000 deaths over the past ten years. Halving the prevalence over the period would save 49 000 child lives. The higher prevalence and higher mortality rates in western provinces mean that even with only 28% of the Chinese population, over half of child deaths there are related to vitamin A.JAYROSS CHUN-MINGCHEN WUHE GANGFU YU-YINGWANG ZHEN-YINGFU MING-XIACHEN 2003Biomedical and Environmental Sciences2003,16,2:6
3Geochemical identification of coal-sourced oils and inter-bedded shale-sourced oils as revealed by compound specific carbon isotopic analysis显示文摘To date, questions remain as to how to differentiate between coal- and interbedded shale-sourced oils in coal measures. Based on the hypothesis that δ13C value of sedimentary organic matter is controlled by the depositional environment and productivities of biota grown in such depositional setting, this note examines compound specific carbon isotopic profiles from coal and interbedded shale extracts using the gas chromatography-isotope ratio mass spec-trometry technique (GC/IRMS). The results show that compound specific carbon isotope values from coal extracts are enriched in 13C relative to that of interbedded shale extracts, and provide useful information in characterizing coal- and interbedded shale-sourced oils in coal measures. An example for its successful application from the Turpan Basin, Northwestern China is presented.SUN Yongge WANG Zhiyong SHENG Guoying ZHANG Shihuan PENG Ping’an FU Jiamo WANG Wuhe YUAN Mingshen 2001Chinese Science Bulletin2001,46,20:2

5All-angle optical switch based on the zero reflection effect of graphene–dielectric hyperbolic metamaterials显示文摘We have studied a switchable hyperbolic metamaterial composed of a graphene–dielectric periodic structure.By tuning the chemical potential of all graphene sheets simultaneously, the isofrequency curve can switch between an ellipse and a hyperbola conveniently. In particular, a special hyperbolic isofrequency curve with its asymptote perpendicular to the interface is obtained and used to realize the zero reflection effect. Furthermore, a zeroreflection-based optical switch working in the terahertz spectrum is demonstrated. Its bandwidth can be efficiently adjusted by geometric parameters such as permittivity and period. Such an optical switch possesses the merits of low loss, high transmittance contrast, high response speed, compact size, high tolerance of chemical potential, and having all incident angles(0°–90°) simultaneously. Such an optical switch holds great potential in many fields,such as data storage, beam steering, and integrated photonic circuits.WENYAO LIANG ZHENG LI YU WANG WUHE CHEN ZHIYUAN LI 2019Photonics Research2019,7,3:1
