- In the clinical settings, different anthropometric indicators like neck circumference (NC), waist circumference (WC), midupper arm circumference (MUAC), waist-to-height ratio (WHtR), and arm-to-height ratio (AHtR) have been suggested for evaluating overweight and obesity in children. The comparative ability of these indicators in Pakistan is yet unknown. This study is aimed at examining the validity of different anthropometric indicators of overweight and obesity simultaneously and at determining their superlative cut-off values that would correctly detect overweight and obesity in children. For this purpose, the dataset of anthropometric measurements height, weight, WC, MUAC, and NC of 5,964 Pakistani children, aged 5-12 years collected in a cross-sectional multiethnic anthropometric survey (MEAS), was used. Receiver operating characteristic (ROC) curve analysis was performed to assess the validity of different anthropometric indicators. The most sensitive and specific cut-off points, positive and negative predictive values of each indicator were also calculated. The results of the ROC curve indicated that all the studied indicators had a good performance but the indicators AHtR and WHtR had the highest value of the area under the curve (AUC) for the screening of children with overweight and obesity (AUC > 0.80). In the overall sample, AHtR, WHtR, MUAC, WC, and NC cut-off points indicative of overweight, in both boys and girls, were 0.14, 0.46, 18.41 cm, 62.86 cm, and 26.36 cm and 0.14, 0.47, 18.16 cm, 64.39 cm, and 26.54 cm, respectively; the corresponding values for obesity were 0.14, 0.47, 18.67 cm, 62.10 cm, and 26.36 cm and 0.14, 0.48, 20.19 cm, 64.39 cm, and 25.27 cm. We concluded that the sex-specific cut-off points for AHtR, WHtR, MUAC, WC, and NC can be used to diagnose overweight and obesity in Pakistani children.

- Purpose - The concept of Triple Helix relates to collaboration between universities, governments and industry. Such collaboration can take different forms in different countries. This paper examines collaboration between universities and industry in China, specifically in the city of Hefei in Anhui province, one of the most rapidly developing regions in the country. In so doing, it seeks to address the research question: How does industry collaborate with universities in order to acquire commercialized knowledge? Design/ Methodology/ Approach - The study is qualitative, based on interviews with experts in R & D, and Intellectual Property Rights from high-tech companies based in Hefei. We analyzed our findings using a conceptual framework that focuses on Knowledge Transfer and Innovation Diffusion (Liyanage et al, 2012). Our study describes and discusses the entire process, from an initial awareness of new knowledge to its eventual acquisition.Findings and implications - We conclude that Chinese high-tech companies design comprehensive strategies for the acquisition of knowledge generated from external sources. These strategies are based on local, provincial and state government industrial policies that aim to support collaboration with universities and implement external knowledge in existing systems.Originality - Commercialized knowledge put into practice by industries for their own innovation and commercial purposes.Limitation - We interviewed industrial experts from three high-tech companies in the city of Hefei, which is located in an industrial area of Anhui province.

- Introduction. This paper focuses on knowledge generation and the way in which it is transferred from universities to industry. Most well reputed universities have several departments and university-run enterprises that engage in research. The purpose of these research units is to help universities provide breakthrough innovation through the generation of new knowledge.Problem Statement. For this we chose to study China's University Technology Transfer Offices (UTTOs) to gather concrete evidence of university knowledge generation for commercial use in industry. The objective of this study is get indepth information about the role of UTTOs in the transfer of such knowledge.Purpose. The generation of new knowledge contributes to the field of science and technology; in turn, industry can use this knowledge to produce new innovative products or improve existing ones. This study aims to identify the process of knowledge transfer from universities to industry in China.Materials and Methods. Our study was carried out as a qualitative case study in the Anhui province of China. Data was mainly collected through semi-structured interviews with technology transfer experts working in technology transfer offices. Collected data were analyzed using a knowledge transfer model with six phases: 1) awareness, 2) acquisition, 3) transformation, 4) association, 5) application, and 6) feedback.Results. In China, universities and their research groups dominate in the generation and commercialization of research results, with UTTOs acting as technology bridges between the two parties, as well as providing legal and business services.Conclusions. This paper contributes by offering a detailed description of the knowledge transfer process and specifically the role and activities of UTTOs. This research also helps Chinese and international researchers currently carrying out research on the technology transfer process in China.

- The concept of Triple Helix relates to collaboration between universities, governments and industry. Such collaboration can take different forms in different countries. This paper describes collaboration between universities and government in China, specifically in the city of Hefei in Anhui province, one of the most rapidly developing regions in the country. The research question is: How can bi-lateral research collaboration be a source of knowledge generation and commercialization for use in industry?The study is qualitative, involving individual and group interviews with university team leaders and team members from successful projects. Government representatives in China were also interviewed. We used the SECI knowledge creation method to analyze the findings. We also describe the collaboration process from idea and application through to review, funding, realization and commercialization. Our study shows that the government in China plays a dominant role in the process of knowledge creation and commercialization. We conclude that collaboration is a source of new knowledge generation and that the government plays a key role by funding universities and creating a research environment that meets the policy requirements of industry today. In particular, we show that universities and their research groups use resources, such as skilled manpower, laboratories and equipment, to accomplish tasks within a set timeframe.

- Cadmium (Cd) contamination and soil salinity are the main environmental issues reducing crop productivity. This study aimed to examine the combined effects of salinity (NaCl) and Cd on the physiological and biochemical attributes of quinoa (Chenopodium quinoa Willd.). For this purpose, 30-day-old plants of quinoa genotype “Puno” were transplanted in Hoagland's nutrient solution containing diverse concentrations of Cd: 0, 50, 100, 200 µM Cd, and salinity: 0, 150, and 300 mM NaCl. Results demonstrated that plant growth, stomatal conductance, and pigment contents were significantly lower at all Cd concentrations than the control plants. Quinoa plants exhibited improved growth and tolerance against Cd when grown at a lower level of salinity (150 mM NaCl) combined with Cd. In contrast, the elevated concentration of salinity (300 mM NaCl) combined with Cd reduced shoot and root growth of experimental plants more than 50%. Combined application of salinity and Cd increased Na (25-fold), while lessened the Cd (twofold) and K (1.5-fold) uptake. A blend of high concentrations of Na and Cd caused overproduction of H2O2 (eightfold higher than control) contents and triggered lipid peroxidation. The activities of antioxidant enzymes: ascorbate peroxidase (APX), catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD) were 13, 12, 7 and ninefold higher than control to mitigate the oxidative stress. Due to restricted root to shoot translocation, and greater tolerance potential against Cd, the quinoa genotype, Puno, is suitable for phytostabilization of Cd in saline soils.

- Coarse Grained Reconfigurable Architectures (CGRAs) are emerging as enabling platforms to meet the high performance demanded by modern applications (e.g. 4G, CDMA, etc.). Recently proposed CGRAs offer runtime parallelism to reduce energy consumption (by lowering voltage/frequency). To implement the runtime parallelism, CGRAs commonly store multiple compile-time generated implementations of an application (with different degree of parallelism) and select the optimal version at runtime. However, the compile-time binding incurs excessive configuration memory overheads and/or is unable to parallelize an application even when sufficient resources are available. As a solution to this problem, we propose Transformation based dynamic Parallelism (TransPar). TransPar stores only a single implementation and applies a series for transformations to generate the bitstream for the parallel version. In addition, it also allows to displace and/or rotate an application to parallelize in resource constrained scenarios. By storing only a single implementation, TransPar offers significant reductions in configuration memory requirements (up to 73% for the tested applications), compared to state of the art compaction techniques. Simulation and synthesis results, using real applications, reveal that the additional flexibility allows up to 33% energy reduction compared to static memory based parallelism techniques. Gate level analysis reveals that TransPar incurs negligible silicon (0.2% of the platform) and timing (6 additional cycles per application) penalty.

- Background Up-to-date evidence on levels and trends for age-sex-specifi c all-cause and cause-specifi c mortality is essential for the formation of global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013) we estimated yearly deaths for 188 countries between 1990, and 2013. We used the results to assess whether there is epidemiological convergence across countries. Methods We estimated age-sex-specifi c all-cause mortality using the GBD 2010 methods with some refinements to improve accuracy applied to an updated database of vital registration, survey, and census data. We generally estimated cause of death as in the GBD 2010. Key improvements included the addition of more recent vital registration data for 72 countries, an updated verbal autopsy literature review, two new and detailed data systems for China, and more detail for Mexico, UK, Turkey, and Russia. We improved statistical models for garbage code redistribution. We used six different modelling strategies across the 240 causes; cause of death ensemble modelling (CODEm) was the dominant strategy for causes with sufficient information. Trends for Alzheimer's disease and other dementias were informed by meta-regression of prevalence studies. For pathogen-specifi c causes of diarrhoea and lower respiratory infections we used a counterfactual approach. We computed two measures of convergence (inequality) across countries: the average relative difference across all pairs of countries (Gini coefficient) and the average absolute difference across countries. To summarise broad findings, we used multiple decrement life-tables to decompose probabilities of death from birth to exact age 15 years, from exact age 15 years to exact age 50 years, and from exact age 50 years to exact age 75 years, and life expectancy at birth into major causes. For all quantities reported, we computed 95% uncertainty intervals (UIs). We constrained cause-specific fractions within each age-sex-country-year group to sum to all-cause mortality based on draws from the uncertainty distributions. Findings Global life expectancy for both sexes increased from 65.3 years (UI 65.0-65.6) in 1990, to 71.5 years (UI 71.0-71.9) in 2013, while the number of deaths increased from 47.5 million (UI 46.8-48.2) to 54.9 million (UI 53.6-56.3) over the same interval. Global progress masked variation by age and sex: for children, average absolute diff erences between countries decreased but relative diff erences increased. For women aged 25-39 years and older than 75 years and for men aged 20-49 years and 65 years and older, both absolute and relative diff erences increased. Decomposition of global and regional life expectancy showed the prominent role of reductions in age-standardised death rates for cardiovascular diseases and cancers in high-income regions, and reductions in child deaths from diarrhoea, lower respiratory infections, and neonatal causes in low-income regions. HIV/AIDS reduced life expectancy in southern sub-Saharan Africa. For most communicable causes of death both numbers of deaths and age-standardised death rates fell whereas for most non-communicable causes, demographic shifts have increased numbers of deaths but decreased age-standardised death rates. Global deaths from injury increased by 10.7%, from 4.3 million deaths in 1990 to 4.8 million in 2013; but age-standardised rates declined over the same period by 21%. For some causes of more than 100 000 deaths per year in 2013, age-standardised death rates increased between 1990 and 2013, including HIV/AIDS, pancreatic cancer, atrial fibrillation and flutter, drug use disorders, diabetes, chronic kidney disease, and sickle-cell anaemias. Diarrhoeal diseases, lower respiratory infections, neonatal causes, and malaria are still in the top five causes of death in children younger than 5 years. The most important pathogens are rotavirus for diarrhoea and pneumococcus for lower respiratory infections. Country-specific probabilities of death over three phases of life were substantially varied between and within regions. Interpretation For most countries, the general pattern of reductions in age-sex specifi c mortality has been associated with a progressive shift towards a larger share of the remaining deaths caused by non-communicable disease and injuries. Assessing epidemiological convergence across countries depends on whether an absolute or relative measure of inequality is used. Nevertheless, age-standardised death rates for seven substantial causes are increasing, suggesting the potential for reversals in some countries. Important gaps exist in the empirical data for cause of death estimates for some countries; for example, no national data for India are available for the past decade.

- Significant technological advancement in the current electronic era has influenced the work processes of private and government business entities. E-Government is one such area where almost every country is emphasizing and automating their work processes. Software architecture is the integral constituent of any software system with not only cumbersome modeling and development but require heedful evaluation. Considering this aspect we have highlighted in this paper, security evaluation of an ongoing e-society project ESAM using Architectural Tradeoff Analysis Method (ATAM). ESAM is a web based system intended to provide e-services to the Swedish community residents. ATAM is primarily used for architectural evaluation aligned with the quality goals i.e. performance, availability and modifiability of an organization. We present research analysis for characterization, stimuli, and architectural decisions to evaluate software architecture with respect to security measures using ATAM. This security characterization will serve as a tool to evaluate security aspects of a software architecture using ATAM. We believe that ATAM capability of evaluating software security will provide potential benefits in secure software development.
