Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...

Community‐informed and codesigned research to understand the impacts of railways on wildlife
Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...

Research on Life Distribution Model of Cancer Patients Under Random Censoring Life Test——based on the Survey of Tumor Patients in a Hospital in Fujian Province from 2003 to 2007 [PDF]
本文基于福建省某医院对2003-2007年肿瘤患者的调查,按住院人数统计,对顺位前三类癌症患者的寿命分布模型进行了研究。研究发现:(1)40-50岁是女性子宫肿瘤发病的高峰期,并且有逐年增长的趋势;(2)剔除女性患子宫肿瘤人数的影响,肿瘤发病的高峰期转移到60-70岁这个年龄段,表现出其它肿瘤多发于老年人,而且肺癌、胃癌、肝癌患者人数尤为突出;(3)肺癌、胃癌、肝癌患者的寿命分布属同一分布族,并且均能通过随机截尾数据下的H-P检验。Based on the survey of tumor ...

Monitoring population extinction risk with community science data
Our modelling framework provides a robust, computationally efficient and easy‐to‐apply tool for monitoring local persistence probability that can support global conservation efforts. This will complement the monitoring of species population viability in places where standardized monitoring is still lacking, but community science observations are common.

The Application of Competing Risk Model on the Prediction Study of Prognosis for Female Breast Cancer [PDF]
目的:通过研究女性乳腺癌患者的术后生存结果,分析评价临床预后因素对女性乳腺癌的影响,探索竞争风险模型在乳腺癌患者预后预测中的应用,并与传统生存分析结果进行比较。 方法:通过调查的方法,获取厦门市及武汉市4家医院1998年至2008年入院接受手术治疗的乳腺癌患者的临床资料。生存分析中的单变量分析以K-M方法进行,用Log-rank法检验生存差异,采用Cox比例风险模型进行多因素分析。在考虑竞争风险的情况下,采用非参数方法计算累积风险率。采用原因别风险模型进行多因素分析,并评价复发的影响因素 ...

Abstract Objectives Neonates with critical congenital heart disease (CCHD) are at risk for adverse early brain development and long‐term neurodevelopmental sequelae. Insulin‐like growth factor‐1 (IGF‐1) and insulin‐like growth factor binding protein‐3 (IGFBP‐3) are essential contributors to brain growth and maturation.
