AP clustering arithmetic is used to cluster training samples according to their operating points. Then, the sub-models are estimated by Gaussian Process Regression (GPR). Finally, in order to get a global probabilistic prediction, Bayesian committee mactnne is used to combine the outputs of the sub-estimators. The proposed method has been applied to predict the light naphtha end point in hydrocracker fractionators. Practical applications indicate that it is useful for the online prediction of quality monitoring in chemical processes.展开更多

On the basis of the empirical investigation of countryside in Sichuan Province, the offside and vacancy of the administration of the "two committees in village" in the villagers′ autonomy are studied tentatively. The results show that the offside and vacancy of the "two committees in village" can be divided into three types, covering the village party branch-dominated, the villagers′ committee-dominated type and the antagonism of the two village committees. The reasons for the offside and vacancy of administration of the "two committees in village" are analyzed, including the fragility of the two committees of the village; the imbalanced power sources of the two committees of the village; the imbalance of the competition for interests of the two committees and the negative effects of traditional politics and culture. The countermeasures are put forward, for example, reinforcing the system construction of rural grassroots organizations; expanding the democratic election modes such as "two-vote system " and "selecting one from the two recommended"; establishing the coordinative and supervisory mechanisms between the two committees in the village and introducing into college-graduate village officials to improve the quality of rural cadres.展开更多

The enrolled patients were divided into?ⅠB and?ⅡA groups based on tumor size according to the 8^(th) edition AJCC criteria. Clinical characteristics, including age, gender, race, tumor size, primary site, and grade were summarized. Univariate and multivariate analyses were performed to explore the prognostic factors of the?ⅠB and?ⅡA stages of pancreatic cancer under new criteria.RESULTS A total of 1349 pancreatic cancer patients were included. More patients had stage?ⅠB rather than stage?ⅡA. Stage?ⅠB tumors(54.85%) were mainly located in the head of the pancreas, while stage?ⅡA tumors were more often located in the tail and head of the pancreas(35.21% and 31.75%, respectively). The survival time of stage?ⅠB and?ⅡA patients had no significant difference. Univariate and multivariate analyses indicated that the prognostic factors of survival for stage?ⅠB and?ⅡA patients were different. for stage?ⅠB patients, age and primary site were the independent prognostic factors; for stage?ⅡA patients, age and grade were the independent prognostic factors. The risk of death was lower among patients aged ≤ 65 years than those aged > 65 years.CONCLUSION The prognostic factors for stage?ⅠB and?ⅡA patients are different, but age is the independent prognostic factor for all patients. The survival time of stage?ⅠB and?ⅡA patients has no significant difference.展开更多
