| 1 | Moving collocation methods for time fractional differential equations and simulation of blowup显示文摘A moving collocation method is proposed and implemented to solve time fractional differential equations. The method is derived by writing the fractional differential equation into a form of time difference equation. The method is stable and has a third-order convergence in space and first-order convergence in time for either linear or nonlinear equations. In addition, the method is used to simulate the blowup in the nonlinear equations. | MA JingTang1 & JIANG YingJun2 1School of Economic Mathematics, Southwestern University of Finance and Economics, Chengdu 611130, China 2Department of Mathematics and Scientific Computing, Changsha University of Science and Technology, Changsha 410076, China | 2011 | Science China Mathematics2011，54，3： | 7 |
| 2 | The Development of Leisure Agriculture Based on Characteristics of Land Resource Utilization显示文摘Based on analysis of geographical and location advantages of Qiaocheng District,we discussed characteristics of land utilization and local industry.

| 3 | Benzylphenethylamine Alkaloids from the Bulbs and Flowers of Lycoris radiata显示文摘Objective To study the benzylphenethylamine alkaloids from the bulbs and flowers of Lycoris radiata.Methods Alkaloids were isolated by various column chromatographic methods and their structures were identified by spectral data.Results Fifteen known benzylphenethylamine alkaloids were isolated and identified as lycoramine(1),O-demethyllycoramine(2),N-demethyllycoramine(3),galanthamine(4),lycorine(5),caranine(6),ungminorine(7),narciclasine(8),5-hydroxy-10-O-demethyl-homolycorine(9),hippeastrine(10),ungerine(11),hippeastrine N-oxide (12),O-demethylhaemanthamine(13),haemanthidine(14),and 8-demethoxyhostasine(15).Conclusion Compound 15 is first isolated from the plants in Amaryllidaceae,compounds 3,6,9,and 11 are first reported from the plants in Lycoris Herb.,and compounds 2,7,and 14 are isolated from L.radiata for the first time.The1 3C-NMR data of compouds 3,7,and 12 are first reported in the present study.Furthermore,the galasine-type alkaloid is isolated from the plants of Lycoris Herb.for the first time. | WANG Huan1,2,3,WANG Yue-hu2,ZHAO Fu-wei2,HUANG Qiao-qin2,3,XU Jin-jin2,3,MA Li-juan1,2,LONG Chun-lin1,2 1.College of Life and Environmental Sciences,Minzu University of China,Beijing 100081,China 2.Key Laboratory of Economic Plants and Biotechnology,Kunming Institute of Botany,the Chinese Academy of Sciences,Kunming 650204,China 3.Yunnan Agricultural University,Kunming 650201,China | 2011 | Chinese Herbal Medicines2011，3，1： | 4 |
| 4 | BATE curve in assessment of clinical utility of predictive biomarkers显示文摘In this paper,for time-to-event data,we propose a new statistical framework for casual inference in evaluating clinical utility of predictive biomarkers and in selecting an optimal treatment for a particular patient.This new casual framework is based on a new concept,called Biomarker Adjusted Treatment Effect (BATE) curve.The BATE curve can be used for assessing clinical utility of a predictive biomarker,for designing a subsequent confirmation trial,and for guiding clinical practice.We then propose semi-parametric methods for estimating the BATE curves of biomarkers and establish asymptotic results of the proposed estimators for the BATE curves.We also conduct extensive simulation studies to evaluate finite-sample properties of the proposed estimation methods.Finally,we illustrate the application of the proposed method in a real-world data set. | ZHOU XiaoHua 1,2,3,& MA YunBei 4,5 1 Northwest HSR&D Center of Excellence,VA Puget Sound Health Care System,Seattle,WA 98198,USA 2 Department of Biostatistics,University of Washington,Seattle,WA 98198,USA 3 Beijing International Center for Mathematical Research,Peking University,Beijing 100871,China 4 Department of Operations Research and Financial Engineering,Princeton University,Princeton,NJ 08540,USA 5 School of Statisitcs,Southwest University of Finance and Economics,Chengdu 611130,China | 2012 | Science China Mathematics2012，55，8： | 2 |
| 5 | Research on Rural Consumer Demand in Hebei Province Based on Principal Component Analysis显示文摘By selecting the time sequence data concerning influencing factors of rural consumer demand in Hebei Province from 2000 to 2010,this paper uses the principal component analysis method in multiplex econometric statistical analysis,constructs the principal component of consumer demand in Hebei Province,conducts regression on the dependent variable of consumer spending per capita in Hebei Province and the principal component of consumer demand so as to get principal component regression,and then conducts quantitative and qualitative analysis on the principal component.The results show that total output value per capita (yuan),employment rate,and income gap,are correlative with rural residents' consumer demand in Hebei Province positively;consumer price index,upbringing ratio of children,and one-year interest rate are correlative with rural residents' consumer demand in Hebei Province negatively;the ratio of supporting the elderly and medical care spending per capita are correlative with rural residents' consumer demand in Hebei Province positively.The corresponding countermeasures and suggestions are put forward to promote residents' consumer demand in Hebei Province as follows:develop county economy in Hebei Province and increase rural residents' consumer demand;use industry to support agriculture and coordinate urban-rural development;improve rural medical care and health system and resolve actual difficulties of the masses. | MA Hui-zi,ZHAO Bang-hong,XUAN Yong-sheng College of Economics and Trade,Agricultural University of Hebei,Baoding 071000,China | 2011 | Asian Agricultural Research2011，3，5： | 2 |
