The NPPCDS consists of two modules: an automatic correction module and a graphical display module. The automatic correction module automatically corrects the T213 NPP at regularly scheduled time intervals, while the graphical display module interacts with users to display the T213 NPP and its correction results. The system helps forecasters extract the most relevant information at a quick glance without extensive post-processing. It is simple, easy to use, and computationally efficient, and has been running stably at Huludao Meteorological Bureau in Liaoning Province of China for the past three years. Because of its low computational costs, it is particularly useful for meteorological departments that lack advanced computing capacity and still need to make short-range weather forecasting.展开更多

This emerging market, called class C, which is incorporated in part by the low-income segment, presents distinct characteristics and needs and for this precise reason eventually burdens the short-term production of Brazilian companies, which feel the need to opt for the importation of basic commodities, manufactured, and semi-manufactured goods, in order to maintain a market share and return on their investments. Although this fact is actually part of a trend of global economic transformation, here it is due to a number of irregular actions taken by the Brazilian government facing a short-term political need. Stemming from quantitative researches and qualitative data, this paper sought to learn more about the consumers' profile and draw up some recommendations for the organizations, in order to be better prepared to face this new demand. This paper also sought to know the actions already undertaken by a large cosmetics company, parts of whose products aim at class C.展开更多

Three interactive versions (low, medium, and high) of a website for a fictitious laptop brand were designed. An online experiment was conducted 180 students participated in the study. Data analysis indicated that higher levels of trust and satisfaction were generated when participants were exposed to the low interactive version of the website. Regarding the four facets of Experiential Value, aesthetics and customer return on investment (croi) have positive relationship with both trust and satisfaction in the brand website. Playfulness appears to have negative whereas excellence does not have significant relationship with trust and satisfaction. Limitations and guidelines for future research are provided.展开更多

Methods A 6-year-old girl was diagnosed muscular ventricularseptal defect and left ventricular aneurysm 2d after automobile accident and underwent ventricular septal defect re-pair 2 weeks after injury. Another 9-year-old boy was diagnosed severe mitral regurgitation resulted from rupture ofposterior papillary muscle 9d after automobile accident and underwent mitral valvuloplasty 2 weeks after injury.Results Heart function of the first patient was in New York Heart Association (NYHA) class echocardiographyshowed no residual septal defect and the size of left ventricular aneurysm reduced. Heart function of the second pa-tient is in NYHA class echocardiography showed mild mitral regurgitation. Conclusion Blunt traumaticheart disease occurs either because of heart compression between sternum and the spine and/or because of myocardi-al contusion; A more aggressive strategy with surgical treatment earlier before deterioration of heart function is ad-vocated; Earlier surgical correction of anatomic deformity will achieve a good result and a long time follow-up isnecessary.展开更多

High correlations ranging from 0.973 to 0.999 indicate that ERA-Interim could capture the annual cycle very well. However, an average root-meansquare error(rmse) of 3.7°C for all stations reveals that ERA-Interim could not be applied directly for the individual sites. The biases can be mainly attributed to the altitude differences between ERA-Interim grid points and stations. An elevation correction method based on monthly lapse rates is limited to reduce the bias for all stations. Generally, ERA-Interim captured the Plateau-Wide annual and seasonal climatologies very well. The spatial variance is highly related to the topographic features of the TP. The temperature increases significantly(10°C- 15°C) from the western to the eastern Tibetan Plateau for all seasons, in particular during winter and summer. A significant warming trend(0.49°C/decade) is found over the entire Tibetan Plateau using station time series from 1979-2010. ERA-Interim captures the annual warming trend with an increase rate of 0.33°C /decade very well. The observation data and ERA-Interim data both showed the largest warming trends in winter with values of 0.67°C/decade and 0.41°C/decade, respectively. We conclude that in general ERA-Interim captures the temperature trends very well and ERA-Interim is reliable for climate change investigation over the Tibetan Plateau under the premise of cautious interpretation.展开更多

Therefore, the valuation, even if reflected in accounting reports, is far from objective, and each company considers it in accordance with their sectors or auditors. Auditors, consultants, and business schools are developing alternative tools for measuring these assets, but there is not a consensus formula that quantifies the business value of intangibles. In recent years, communication analysts and consultants have developed brand valuation and reputation methodologies, which are starting to have a relative weight in business management. The proposed research work is a review of the current methodologies of reputation valuation as a starting point for creating a reference model formula for the valuation of intangibles that provide professionals and experts in the field with a worldwide recognized tool.展开更多

The ICM makes use of the continuity in time of the forecast errors at different forecast times to improve the accuracy of large scale NPP. To apply the ICM in China, an ensemble correction scheme is designed to correct the T213 NPP(the most popular NPP in China) through different statistical methods. The corrected T213 NPP(ICM T213 NPP) are evaluated by four popular indices: Correlation coefficient, climate anomalies correlation coefficient, root-mean-square-errors(RMSE), and confidence intervals(CI). The results show that the ICM T213 NPP are more accurate than the original T213 NPP in both the training period(2003–2008) and the validation period(2009–2010). Applications in China over the past three years indicate that the ICM is simple, fast, and reliable. Because of its low computing cost, end users in need of more accurate short-range weather forecasts around China can benefit greatly from the method.展开更多

These modifications facilitated soybean transformation manipulation and improved transformation reproducibility and efficiency. Using a linear minimal gus gene cassette as the foreign DNA, a maximum transformation frequency of 11% was obtained in flowers of the soybean cultivar ‘Liaodou 14’ with their styles mostly removed, whereas removal of only the stigma, partial style cutting and partial ovary cutting gave transformation frequencies of 0%, 1%, and 2%, respectively. An average transformation frequency of 8.2% was obtained when 619 flowers from three soybean cultivars (‘Liaodou 14’, ‘Liaodou 13’, and ‘Tiefeng 29’) were transformed by this optimized method. Southern blotting analysis showed that the gus reporter gene (encoding β-glucuronidase) was stably inherited with a simple pattern. Reverse transcription-polymerase chain reaction (RT-PCR) and GUS staining confirmed the expression of the gus gene in transgenic plants.展开更多

This paper provides an example of how to choose and devise verification methods and techniques according to different space weather forecast products. Solar proton events(SPEs) are hazardous space weather events, and forecasting them is one of the major tasks of the Space Environment Prediction Center(SEPC) at the National Space Science Center of the Chinese Academy of Sciences. Through analyzing SPE occurrence characteristics, SPE forecast properties, and verification requirements at SEPC, verification methods for SPE probability forecasts are identified, and verification results obtained. Overall, SPE probability forecasts at SEPC exhibit good accuracy, reliability, and discrimination. Compared with climatology and persistence forecasts, the SPE forecasts are more accurate. However, the forecasts for SPE onset days are substantially underestimated and need to be considerably improved.展开更多
