1基于Logistic的大兴安岭雷击火预测模型显示文摘利用大兴安岭雷击数据、雷击火数据、气象数据和GIS空间分析,引入加拿大雷击火预测模型和Logistic回归模型,建立了黑龙江大兴安岭雷击火预测模型。模型除了使用加拿大雷击火预测模型的固有参数外,还引入了影响火灾蔓延的地形因子作为模型参数。利用实际数据进行模型检验,结果表明:修正后的预测模型在特定区间的雷击火预测结果较为理想,总体预测正确率能达到30%以上,与加拿大预测正确率基本一致;也说明了基于logistic回归的加拿大雷击火预测模型,经过参数修正后同样适用于我国大兴安岭地区,可为该地区的雷击火预防提供可靠的数据支持。彭欢 史明昌 孙瑜 Mike Wotton 2014东北林业大学学报2014,42,7:13
2黑龙江大兴安岭雷击火概率预测模型研究显示文摘结合黑龙江大兴安岭雷击火发生特点及该地区的气象条件,引用加拿大天气指标(FWI)系统,使用2005年至2010年每日的闪电定位数据、天气数据、雷击引发的火灾数据,利用二元Logistic回归模型,采用全部进入法建立回归模型,最后检验分析显示:模型拟合效果较为理想,为预测黑龙江大兴安岭地区雷击火发生概率提供依据。朱沛林 史明昌 Mike Wotton 方艳霞 刘思林 孙瑜 2014中南林业科技大学学报2014,34,8:11
3cffdrs: an R package for the Canadian Forest Fire Danger Rating System显示文摘Introduction:The Canadian Forest Fire Danger Rating System(CFFDRS)is a globally known wildland fire risk assessment system,and two major components,the fire weather index system and the fire behavior prediction system,have been extensively used both nationally and internationally to aid operational wildland fire decision making.Methods:In this paper,we present an overview of an R package cffdrs,which is developed to calculate components of the CFFDRS,and highlight some of its functionality.In particular,we demonstrate how these functions could be used for large data analysis.Results and Discussion:With this cffdrs package,we provide a portal for not only a collection of R functions dealing with all available components in CFFDRS but also a platform for various additional developments that are useful for the understanding of fire occurrence and behavior.This is the first time that all relevant CFFDRS methods are incorporated into the same platform,which can be accessed by both the management and research communities.Xianli Wang B.Mike Wotton Alan S.Cantin Marc-AndréParisien Kerry Anderson Brett Moore Mike D.Flannigan 2017Ecological Processes2017,6,1:4

6Perinatal and early life risk factors for inflammatory bowel disease显示文摘AIM:To investigate associations between perinatal risk factors and subsequent inflammatory bowel disease (IBD) in children and young adults.METHODS:Record linked abstracts of birth registrations,maternity,day case and inpatient admissions in a defined population of southern England.Investigation of 20 perinatal factors relating to the maternity or the birth:maternal age,Crohn's disease (CD) or ulcerative colitis (UC) in the mother,maternal social class,marital status,smoking in pregnancy,ABO blood group and rhesus status,pre-eclampsia,parity,the infant's presentation at birth,caesarean delivery,forceps delivery,sex,number of babies delivered,gestational age,birthweight,head circumference,breastfeeding and Apgar scores at one and five minutes.RESULTS:Maternity records were present for 180 children who subsequently developed IBD.Univariate analysis showed increased risks of CD among children of mothers with CD (P=0.011,based on two cases of CD in both mother and child) and children of mothers who smoked during pregnancy.Multivariate analysis confirmed increased risks of CD among children of mothers who smoked (odds ratio=2.04,95% CI=1.06-3.92) and for older mothers aged 35+ years (4.81,2.32-9.98).Multivariate analysis showed that there were no significant associations between CD and 17 other perinatal risk factors investigated.It also showed that,for UC,there were no significant associations with the perinatal factors studied.CONCLUSION:This study shows an association between CD in mother and child;and elevated risks of CD in children of older mothers and of mothers who smoked.Stephen E Roberts Clare J Wotton John G Williams Myfanwy Griffith Michael J Goldacre 2011World Journal of Gastroenterology2011,17,6:2
7Rejection of Permacol~ mesh used in abdominal wall repair:A case report显示文摘Permacol mesh has shown promise when used in abdominal wall repair,especially in the presence of a contaminated surgical field.This biomaterial,derived from porcine dermis collagen,has proposed advantages over synthetic materials due to increased biocompatibility and reduced foreign body reaction within human tissues.However,we present a case report describing a patient who displayed rejection to a Permacol mesh when used in the repair of abdominal wound dehiscence following an emergency laparotomy.Review of the English language literature using PubMed and Medline, showed only two previously published cases of explantation of Permacoldue to sepsis or wound breakdown. The authors believe this is the first case of severe foreign body reaction leading to rejection of Permacol.Both animal and human studies show conflicting evidence of biocompatibility.There are several reports of successful use of Permacolto repair complex incisional herniae or abdominal walls in the presence of significant contamination.It appears from the literature that Permacolis a promising material,but as we have demonstrated,it has the potential to evoke a foreign body reaction and rejection in certain subjects.Franchesca T Wotton Jacob A Akoh 2009World Journal of Gastroenterology2009,15,34:2
