This study evaluates ensemble forecasts with a stochastic kinetic energy backscatter scheme(SKEBS)to predict tropical cyclone(TC)genesis and also to characterize the related ensemble *** sets of ensemble forecasts are generated using an advanced research version of the Weather Research and Forecasting model at 5 km horizontal resolution to predict the genesis of Hurricane Ernesto(2006)and Typhoon Nuri(2008).Ensemble forecasts with SKEBS are compared against a control ensemble forecast with the WRF model using downscaled initial conditions derived from the NCEP Global Ensemble Forecasting *** is found that ensemble forecasts with SKEBS are able to generate probabilistic forecasts for TC genesis and also capable of indicating the forecast *** with the deterministic forecast that fails to predict the genesis of Typhoon Nuri,the ensemble forecast with SKEBS is able to produce the genesis ***,the underdispersion of ensemble forecasts with SKEBS is also present in all cases in terms of the simulation period and over the whole model domain,TC environment,and inner core regions,although it is reduced near the TC inner core *** addition,the initial perturbation–based ensemble forecasts shows slightly less underdispersion compared with the SKEBS ensembles.

The energy consumption of the information and communication technology sector has become a significant portion of the total global energy consumption, warranting research efforts to attempt to reduce it. The pre-requisite for effectual energy management is the availability of the current power consumption values from network devices. Previous works have attempted to estimate and model the consumption values or have measured it using intrusive approaches such as using an in-line power meter. Recent trends suggest that information models are being increasingly used in all aspects of network management. This paper presents a framework developed for enabling the collection of real-time power consumption information from the next generation of networking hardware non-intrusively by employing information models. The experiment results indicate that it is feasible to gather power consumption data using standardized IETF information models, or non-standard customized information models, or through abstracting and exposing the information in a uniform format when no support for the required information models exists. Functional validation of the proposed framework is performed and the results from this research could be leveraged to make energy-efficient network management decisions.

2006全国时间生物医学学术会议

作者： levi Francis

In Southern China,chrono-chemotherapy has been tried to treat nasopharyngeal carcinoma (NPC) patients using 5-Fu combined with platinum complexes. However,there was no enough data about circadian profiles of the circadian profiles of dihydropyrimidine dehydrogenase (DPD), thymidylate synthase (TS) in mRNA level on Chinese NPC patients. In present study,total of 13 NPC patients were involved,9 males and 4 *** veinal blood was collected at 6 time points (12:00,16:00,20:00,and 24:00,04:00,08:00) during a single 24 hours from all the participants. The circadian gene expression profiles of DPD,TS in PBMC were measured using the real-time quantitative RT-PCR method. In addition, the whole-blood reduced Glutathione (GSH), Dihydrouracil and uracil ratios (UH2/U ratios)(an indirect method for measuring DPD activity, HPLC method), plasma cortisol level were also measured. In present study, Mesor (rhythm-adjust mean) of DPD gene copies was 6.21×107±7.76±106 copy/μg RNA (mesor±SEM), and it was 828×103±8.33×102 copy/ug RNA for TS gene. It was of no statistical significance for DPD mRNA expression according to sampling time (ANOVA for Repeated Measures,F= 1.067,P=0.369;Cosinor,P=0.078), and for TS (ANOVA for Repeated Measures, F= 0.505, P = 0.765, Cosinor, P = 0.1068). The plasma cortisol displayed a clearly circadian rhythm and the peak time located at 09:14±01:11 (Corsinor, P < 0.0001). The mean value of UH2/U was 4.80±0.20 and a significant circadian rhythm was not displayed (ANOVA for Repeated Measures, F= 0.352,P = 0.862;Corsinor, P = 03053). The mesor value of GSH was 19.60±1.11 (nmol/L) and GSH displayed a possible circadian rhythm and the acrophase located at 05:02 (ANOVA for Repeated Measures,F= 3.985, P = 0.050;Corsinor, P=0.0645). In conclusion, a clear circadian rhythm was not displayed for DPD gene and TS gene in mRNA level, also not found for DPD activity on Chinese NPC patients, although these patients still maintained an obvious circadian rhythm in
