Considering that ensemble learning is an effective method of reducing the classifmation error of the classifier, this paper proposes a double-layer Bayesian classifier ensembles (DLBCE) algorithm based on frequent itemsets. DLBCE constructs a double-layer Bayesian classifier (DLBC) for each frequent itemset the new instance contained and finally ensembles all the classifiers by assigning different weight to different classifier according to the conditional mutual information. The experimental results show that the proposed algorithm outperforms other outstanding algorithms.展开更多

Methods: 90 patients with primary liver cancer who received interventional therapy from January 2021 to June 2022 in the First Affiliated Hospital of Nanjing Medical University were selected and divided into two groups. The control group received routine nursing, while the observation group received continuous nursing and nutritional support. The differences of each index between the two groups were compared. Results: the changes of serum total protein, albumin and quality of life scores in the observation group were higher than those in the control group (P<0.05);The satisfaction of the observation group was higher than that of the control group (P<0.05). Conclusion: the combination of continuous nursing and nutritional support has a good application effect, which can improve the total protein and albumin levels of patients and can be popularized.展开更多

How to transfer NPP at one scale by the algorithm with smaller error to at another is the urgent problem. Nonlinearity and effects from land cover type are two main problems in NPP scaling. In this paper, the contextural approach based on mixed pixels and support vector machine (SVM) algorithm are used to make the scaling model from the fine resolution (TM) to the coarse resolution (MODIS). Spatial scaling from NPP retrieved from fine resolution data to NPP derived from coarse resolution images is performed, and the correction of scale effect to NPP retrieved from coarse resolution data of MODIS is accomplished. The result shows that the correlation between Rj_coereted of the correction factor for scale effect and 1-Fmiddle dessity grassland estimated by SVM regression model is higher (R2=0.81). Before the correction for scale effect, the correlation between NPPMODIS and NPPTM is lower (R2=0.69; RMSE=3.47), while the correlation between NPPTM and corrected NPPMODIS_corrected is higher (R2=0.84; RMSE= 1.87). Therefore, NPP corrected for scale effect has been greatly improved in both correlation and error.展开更多

Remote sensing technology has been used to monitor net primary productivity (NPP) of ecological system for several years. In this paper, the remotely sensed NPP simulation model of alpine vegetation in Qinghai Province of Tibet Plateau was set up based on the theory of light use efficiency. Firstly a new approach based on mixed pixels and Support Vector Machine (SVM) algorithm were used to correct simulated NPP values derived from Moderate Resolution Imaging Spectroradiometer (MODIS) data. Finally, spatial distribution and monthly variation characteristics of NPP in Qinghai Province detail. The result showed in 2006 were analyzed in that NPP of vegetation in Qinghai Province in 2006 ranged from o to 422 gC/m2/a and the average NPP was 151 gC/m2/a. NPP gradually increased from northwest to southeast. NPP of different vegetation types were obviously different. The average NPP of broad-leaved forest was the largest (314 gC/m2/a), and sparse shrub was the smallest (101 gC/m2/a). NPP in Qinghai Province significantly changed with seasonal variation. The accumulation of NPP was primarily in the period (from April to September) with better moist and heat conditions. In July, the average NPP of vegetation reached the maximum value (43 gC/m2). In our model, the advantage of traditional LUE models was adopted, and our study fully considered typicalcharacteristics of alpine vegetation light use efficiency and environmental factors in the study area. Alpine vegetation is the most important ecological resource of Tibet Plateau, exactly monitoring its NPP value by remote sensing is an effective protection measure.展开更多

Completed responses were received from 193 pharmacies (55.1%). Fifty-five (28.5%) of these pharmacies were approved as meeting the HSP criteria. Some difficulties encountered in registering as an HSP included the preparation of the numerous required documents and placing a health support pharmacist. The obstacles that prevented pharmacists from registering were physical, including “placement of two or more health support pharmacists” and “placement of the required over-the-counter drugs (OTCs).” Based on these, 51.8% of supervising pharmacists stated the opinion that the government should “loosen current criteria.” However, a survey conducted among the 724 participant pharmacists, working in a pharmacy, showed no significant difference in their answering tendencies depending on whether or not they worked at an HSP. This could be attributed to the effort that Min- Iren pharmacies have been putting into health support and primary care functions. Overall, 64.5% of pharmacists working at HSPs were proud that the pharmacy they worked had HSP status. The present survey revealed the physical obstacles of HSP registration. Conformity to the criteria of HSP is essential for performing their fundamental functions as pharmacies. The relaxation of the criteria is anticipated.展开更多
