With a vast territory, the space-time distribution of water resources is uneven in China. There is a great dif ference in natural conditions and farmland management of agricuttural production in different regions. The areal differentiation of agricultural products virtual water is obvious. Comparison with the agricultural products virtual water from 1995 to 2007 in China shows an increase in the first ten vears and a little decrease in recent years. There has been a tendency of increase all the time in Northeast and Northwest. but a decrease after an increase firstly in other regions. The virtual water offood crops is the maximum which accounts for more than 70% in China. and that of vegetables is in a fast growth. The proportion of agricultural products virtual water to the total water resources in each region has a large difference, showing the imbalance of agricultural water in different regions, which accounts for 50%-90% in Northeast, and 125%-185% in North China. Under the guidance of virtual water strategy, based on the differences of resource endowment, each region should adjust agricultural structure, decide production by water, and select water suitable crops. In water-rich region, agricultural produets of high water consumption should be planted appropriately, which will make full use of the abundant local water resources. In water-shortage region the crop production of high water consumption and low efficiency should be depressed, and that of low water consumption and high efficiency should be supported and increased. It will achieve reasonable disposition of water resources, promote ecological restoration and environmental protection, as welt as ensure food security.

当前,消费对中国经济发展的基础性作用越来越重要,这就意味着内需市场规模持续扩张和消费结构优化升级能力,愈发成为决定中国经济高质量发展模式形成的基础条件。打造国民收入可持续增长动力机制,则是推动内需市场规模持续扩张和消费结构优化升级的决定性因素。因此,有必要重新审视和深入分析供给侧—需求侧的共生关系及相互决定关系理论,以及国民收入分配体制中初次分配和再次分配机制及相互关系理论。通过系统性分析可得出,现阶段中国实施“国民收入倍增计划”战略的可行途径及其突出障碍。从国民初次分配机制的角度来看,合理地发挥促进各部门全员劳动生产率和全要素生产率共同可持续提升的基础作用,加快促进生产率和工资收入协同增长机制的形成。从国民再次分配机制的角度来看,加快构建符合中国特色社会主义基本原则的新型企业制度以及金融制度,将之作为“拓宽最为广泛的居民财产性收入渠道”的重要渠道机制。最为重要的是,要切实落实中国的“国民收入倍增计划”战略,在国民初次分配机制和再次分配机制中,均需要政府和市场功能有机结合式的干预和融合发展途径。

研究场景构建中纹理图像的三维特征识别,提高识别准确率。由于图像的效果取决于纹理识别,在三维空间中分析纹理图像时,仅使用聚类算法利用三维图像的空间坐标和三维像素灰度特征对其进行分类识别,忽略了不同方向光照对纹理图像的影响而简单聚类分类,导致因提取的特征信息不足而造成识别准确率不高的问题。因此,提出了一种机器学习的三维特征识别方法。通过变换光照的角度得到不同光照下的纹理图像,提取出多面光照下的三维图像特征信息,并利用机器学习算法对特征信息进行准确训练和分类识别,可避免聚类算法利用信息不足的特征进行分类而造成的识别准确率不高的问题。实验表明,这种方法能够有效提取出特征信息并进行准确分类,具有较高的识别准确率,取得了满意的结果。

Role of Diffusion-weighted and Contrast-enhanced Magnetic Resonance Imaging in Differentiating Activity of Ankylosing Spondylitis

引用

Chinese Medical Journal 2017年第11期130卷 1303-1308页

作者： Ying-Hua Zhao Yan-Yan Cao Qun Zhang Ying-jie Mei Ji-jie Xiao Shao-yong Hu Wei Li Shao-Lin Li Oepartment of Radiology Third Affiliated Hospital of Southern Medical University Orthopaedic Hospital of Guangdong Province Guangzhou Guangdong 510630 China Department of Rheumatology Hospital of Integrated Traditional Chinese Medicine and Western Medicine of Southern Medical University Guangzhou Guangdong 510315 China Department of Rheumatology Third Affiliated Hospital of Southern Medical University Orthopaedic Hospital of Guangdong Province Guangzhou Guangdong 510630 China Department of MR Clinical Science Philips Healthcare Guangzhou Guangdong 510055 China

Background： Previous studies showed that combining apparent diffusion coefficient （ADC） value with the Spondyloarthritis Research Consortium of Canada （SPARCC） index value might provide a reliable evaluation of the activity of ankylosing spondylitis （AS）, and that contrast-enhanced （CE） magnetic resonance imaging （MRI） is unnecessary. However, the results were based on confirming only a small random sample. This study aimed to assess the role of CE-MRI in differentiating the disease activity of AS by comparingADC value with a large sample. Methods： A total of l 15 patients with AS were enrolled in accordance with Bath AS Disease Activity Index and laboratory indices, and 115 patients were divided into two groups, including active group （n = 69） and inactive group （n 46）. SPARCC, ASI, and ADC values were obtained from the short tau inversion recovery （STIR）, diffusion-weighted imaging （DWI）, and CE-MRI, respectively. One-way analysis of variance and receiver operating characteristic analysis were performed for all parameters. Results： The optimal cutoff values （with sensitivity, specificity, respective area under the curve, positive likelihood ratio, and negative likelihood ratio） for the differentiation between active and inactive groups are as follows： SPARCC = 6 （72.06%, 82.61%, 0.836, 4.14, 0.34）; ASI （%） 153 （80.6%, 84.78%, 0.819, 5.3, 0.23）; ADC value - 1.15 × 10 3 mm2/s （72.73% 81.82%, 0.786, 4, 0.33）. No statistical differences were found among the predictive values of SPARCC, △SI, and ADC. Multivariate analysis showed no significant difference between the combination of SPARCC and ADC values with and without ASI. Conclusions： Using large sample, we concluded that the combination of STIR and DWI would play significant roles in assessing the disease activity, and CE-MRI sequence is not routinely used in imaging of AS to avoid renal fibrosis and aggravation of kidney disease.

Molecular marker-assisted selection(MAS) can significantly accelerate and improve the efficiency of the breeding process in seedless grape cultivars. In this study, we developed the KASP_VviAGL11 and VviAGL11_410 markers based on a single nucleotide polymorphism(SNP) site(Chr18: 26889437(A/C)) of the VviAGL11 gene, and compared them with previously reported SSR markers p3_VvAGL11 and 5U_VviAGL11 by testing 101 cultivars and 81 F1 hybrid progenies. The results showed that both of the proposed markers obtained 100% accuracy rates in detecting allele A, which was closely associated with the seedless trait in grapes, while p3_VvAGL11 and 5U_VviAGL11 had lower accuracy rates due to their tendency to produce false positives. After careful evaluation of the technical advantages and disadvantages associated with these markers, we concluded that KASP_VviAGL11 was superior in terms of simplicity,cost-effectiveness, efficiency, and accuracy. Thus, we optimized the process of molecular MAS for seedless grapes,focusing on the KASP_VviAGL11 marker as a central component, to provide key technical support for the development of new seedless grape cultivars.

品牌社区是指一种特定的,不受地域限制的,基于某一品牌崇拜者之间结构化的社会关系而建立的社区。大量研究围绕社会认同理论、计划行为理论等相关理论,试图揭示品牌社区的形成、发展及作用机制。现有研究发现消费者对品牌的态度及其所感受到的主观行为规范等因素会影响个体的社区参与水平,而参与品牌社区有助于社区成员产生品牌认同,进而有效地维持并提高其品牌忠诚度。未来研究应该更多地关注自尊、自我意识以及社会认同威胁等变量。此外,国内研究者还应当考虑到东西方文化差异,促进相关理论及概念的本土化。
