Journal of Diabetes, Volume 15, Issue 1, Page 7-14, January 2023., 2023 Highlights Red blood cell (RBC) lifespan variation, is the main cause of variation in glycosylated hemoglobin (HbA1c), independent of blood glucose levels. This study highlighted the important impact of RBC lifespan on HbA1c test value in T2DM with HbA1c test value <7%. We discovered that the HbA1c test value in type 2 diabetes (T2DM) patients with RBC

Journal of Applied Ecology, Volume 58, Issue 10, Page 2287-2304, October 2021., 2021 Field boundary features have an important role in stabilising pollinator populations and pollination service in rotational systems, although maintenance of larger semi‐natural habitat patches may be more effective for stabilising less mobile solitary bee populations.

Combined effects of life‐history traits and human impact on extinction risk of freshwater megafauna
Conservation Biology, Volume 35, Issue 2, Page 643-653, April 2021., 2021 Abstract Megafauna species are intrinsically vulnerable to human impact. Freshwater megafauna (i.e., freshwater animals ≥30 kg, including fishes, mammals, reptiles, and amphibians) are subject to intensive and increasing threats. Thirty‐four species are listed as critically endangered on the International Union for Conservation of Nature (IUCN).

Load Spectrum Compiling Based on Operation Section Recognition and Fatigue Life Prediction of Wheel Loader Axle Shaft [PDF]
, 2017 为改进轮式装载机可靠性及耐久性设计中数据清洗和分析的方法,以装载机半轴为对象,优化载荷信号去噪和作业段识别的方法。利用小波自适应阈值法去除实测载荷的噪声尖峰和突变信号,并通过迭代平滑滤波法搜寻单个作业周期内同步载荷信号的极值点,识别、划分作业段为＂行走段-铲掘段＂。结合雨流计数和频次外推法编制载荷谱,有限元静力分析,以及Miner准则对装载机半轴进行疲劳寿命分析。结果表明：雨流计数的均幅值结果符合正态分布和三参数威布尔分布的假设性检验,疲劳分析损伤最大节点出现在万向节叉连接处,其寿命为7.22×10 ...
