Background: We previously developed predictive models for 3-month mortality and modified Rankin Score (mRS) after ischemic stroke. Aim: The aim was to test model validity for 3-month mortality and mRS after ischemic stroke in two independent data sets. Methods: Our derivation models used data from 451 subjects with ischemic stroke in 1999 enrolled in the Greater Cincinnati/Northern Kentucky Stroke Study (GCKNSS). We utilized two separate cohorts of ischemic strokes through GCKNSS (460 in 2005 and 504 in 2010) to assess external validity by utilizing measures of agreement between predicted and observed values, calibration, and discrimination using Transparent Reporting of a multivariable prediction model for Individual Prognosis or Diagnosis. Results: The 3-month mortality model performed well in the validation datasets with an average prediction error (Brier score) of 0.045 for 2005 and 0.053 for 2010 and excellent discrimination with an area under the curve of 0.86 (95% CI: 0.79, 0.93) for 2005 and 0.84 (0.76, 0.92) for 2010. Predicted 3-month mRS also performed well in the validation datasets with R2 of 0.57 for 2005 and 0.50 for 2010 and a root mean square error of 0.85 for 2005 and 1.05 for 2010. Predicted mRS tended to be higher than actual in both validation datasets. Re-estimation of the model parameters for age and severe white matter hyperintensity in both 2005 and 2010, and for diabetes in 2005, improved predictive accuracy. Conclusions: Our previously developed stroke models performed well in two study periods, suggesting validity of the model predictions.

作者： Jia Li Li Xiaoping Sun Jindong department of Urban Construction Engineering Beijing Institute of Civil Engineering & Architecture Beijing, 100044 P. R. China

The annular thin film condensation of vapors of wet flue gas in vertical tubes was studied theoretically and experimentally. The convection heat transfer is increased by, the condensation of the condensable gas (water vapor) existing in the wet flue gas. This paper discusses the effects of the condensation of a small amount of water vapor (10%-20% fraction) on convection heat transfer in a vertical tube. The flows (Re=2300-5000) in vertical tube were investigated experimentally. Some interesting results were obtained. The wall temperature was an important factor affecting the condensing rate. The proportion of the sensible and latent changes with the Re number. When the wall temperature is much lower than the saturate temperature of the inlet wet flue gas, the effect of superheat can be neglected. In the concentration range researched the effect of water vapor condensation heat transfer is discussed, but the convection heat transfer of mixture gas can not be neglected.

A los solar blind UV communication channel model is presented in the paper, which consists of three sections: propagation loss section, scattering transmission section and background noise section. los transmission loss model of UV channel is deduced by Lambert law and noise power calculation is also analyzed. Base on them, a practicable calculation method of signal to noise ratio （SNR） is presented, which is a bridge between system parameters and system performances such as BER and limit communication distance in analysis of UV communication. Transmission loss and SNR of los are measured in outdoor experiments. The experiment shows that SNR calculation data agree with the experimental results quite well. The calculation also shows that the limit communication distance of los can achieve 7kms with the UV sensor at present.
