| 1 | New adaptive quasi-sliding mode control for nonlinear discrete-time systems显示文摘A new adaptive quasi-sliding mode control algorithm is developed for a class of nonlinear discrete-time systems, which is especially useful for nonlinear systems with vaguely known dynamics. This design is model-free, and is based directly on pseudo-partial-derivatives derived on-line from the input and output information of the system using an improved recursive projection type of identification algorithm. The theoretical analysis and simulation results show that the adaptive quasi-sliding mode control system is stable and convergent. | Wang Weihong1,2 & Hou Zhongsheng3 1.

| 2 | Environmental and Psycho-social Factors Related to Prostate Cancer Risk in the Chinese Population:a Case-control Study显示文摘Objective To study the risk environmental and psycho-social factors associated to prostate cancer(PCa) in Chinese population. Methods 250 PCa patients and 500 controls were enrolled in this case-control study. Information was collected and logistic regression analysis was used to estimate the odds ratios(OR) and 95% confidence intervals(95% CI) for relationship between lifestyle, eating habits and psycho-social factors with PCa risk. Results Green vegetables and green tea were associated with a decreased risk of PCa(OR=0.39, 95% CI: 0.28-0.53; OR=0.59, 95% CI: 0.40-0.87, respectively). Family history of PCa(OR=7.16, 95% CI: 2.01-25.49), history of prostate diseases(OR=2.28, 95% CI: 1.53-3.41), alcohol consumption(OR=1.97, 95% CI: 1.33-2.90), red meat consumption(OR=1.74, 95% CI: 1.20-2.52), barbecued(OR=2.29, 95% CI: 1.11-4.73) or fried(OR=2.35, 95% CI: 1.24-4.43) foods were related with increased PCa risk. Negative psycho-social factors including occupational setbacks(OR=1.61, 95% CI: 1.00-2.59), marital separation(OR=1.94, 95% CI: 1.29-2.91), self-contained suffering(OR=2.37, 95% CI: 1.58-3.55), and high sensitivity to the personal comments(OR=1.73, 95% CI: 1.18-2.54) were related to PCa. Conclusion Regular consumption of green vegetables and green tea may suggest protective effects on PCa. Alcohol consumption, red meat consumption and barbecued or fried foods were associated with PCa. Negative psycho-social factors may also play a role in the incidence of PCa in Chinese population. | LI Mei Ling LIN Ji HOU Jian Guo XU Lei CUI Xin Gang XU Xing Xing YU Yong Wei HAN Xue WANG Guo Min GUO Jian Ming XU Dan Feng THOMPSON Timothy C CAO Guang Wen ZHANG Hong Wei | 2014 | Biomedical and Environmental Sciences2014，27，9： | 5 |
| 3 | Variations in Wool Growth with Nutrient Supply in Northern China显示文摘Field studies on essessment of nutritional status of the grazing sheep were carried out in each of the three major grassland regions, the eastern Inner Mongolia and beyond grassland, the Inner Mongolia - Ningxia - Gansu grassland and the Xinjiang grassland, in northern China. The results obtained showed that the wool production of fine wool sheep in these regions varied between regions and seasons, with similar seasonal patterns in all regions and that reducing the seasonal variations in nutrient supply would enhance wool production substantially. Nutritional limitations to wool growth of the grazing sheep in these regions were suggested, those were: the shortage of protein supply in winter and early spring; the poor quality of much of the pasture and the hay used as supplements, the low energy intake during winter which probably necessitated the use of body stores to maintain body temperature. | D X Lu,Iner(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)Z C Feng,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)H R Wang,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)R Z Yang,(Xinjiang Institute of Animal Science.Xinjiang Academy of Animal Science.Yiu Hou Road.Urumqi.Xinjiang Uygur Autonomous Region PRC)C T Ma,(Chinese Academy of Agricultural Sciences.Lanzhou.Gansu.PRC)D B Purser,(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)J R Lindsay(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)D W Peter(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014) | 1997 | 畜牧与饲料科学1997，22，S1： | 3 |
