Highlights Patients with type 2 diabetes (T2D) are prone to developing chronic diabetes‐related complications at the microvascular and macrovascular levels. The Computerized Nailfold Video‐Capillaroscopy (CNVC) provides specific information on both quantitative and qualitative characteristics of microvasculature at the level of fingers.

Abstract Surging demand for medicinal plant products may lead to unsustainable harvesting practices, which could put pressure on wild populations. Yet little is known about indigenous harvesters' preferences on key traditional Chinese medicinal plant resources, and how these might affect sustainable use and management.

Highlights This long‐term longitudinal study demonstrates the association between alcohol consumption and health outcomes in patients with abnormal glucose metabolism including type 2 diabetes mellitus and prediabetes. Occasional drinking (less than once a week) reduces the risk of all‐cause mortality, while heavy alcohol consumption (≥30 g/day for men

基于小波变换的2013年芦山MS7.0地震前姑咱台钻孔应变异常时频分析
2013年4月20日芦山MS7.0地震前,四川省姑咱台四分量YRY-4型钻孔应变仪记录到显著的高频应变畸变信号。为了避免该畸变信号的高频部分在时频演化过程中发生频率混叠现象,同时便于讨论同一研究频段内震前更早记录到的弱应变异常时段与显著应变异常时段的相关性,本文对2012年1月1日至2013年4月20日期间姑咱台的钻孔应变数据进行了时频分析,并使用时域分段的小波变换方法,在局部时频谱中提取了应变异常,分析了各应变异常的频率相关性。结果表明,研究频段内存在两个峰值频率 ...

笔者选取了2018年8月3日发生在南京地区的一次正地闪放电过程,利用6站同步的VLF/LF(甚低频/低频)三维闪电探测数据,重点分析了不同频段的地闪回击脉冲波形的定位结果差异性。首先,针对这次地闪回击的原始时域波形,利用巴特沃斯滤波器进行了回击频域信号的任意提取,分别为10 kHz~50 k Hz、10 k Hz~100 kHz、10 kHz~200 kHz、10 kHz~300 kHz、10 kHz~400 kHz、10 k Hz~500 kHz,从而得到不同频段的回击时域波形。然后 ...

一次特大地震会对震中及附近区域热辐射背景场造成较大影响。应用中国静止气象卫星风云二号系列(FY-2C/2E/2F/2G)的亮温资料,通过时频相对功率谱法对2007—2016年(30°N—45°N,135°E—150°E)范围的时频数据进行全时空全频段扫描,得到了2011年3月11日日本MW9.1特大地震的热辐射异常,该异常特征明显且与地震发震构造对应较好。应用时频分析方法分析MW9.1地震对上述扫描区域热辐射背景场的影响,得出2011年的热辐射异常出现时间长、范围大且与其它年份不同 ...

Automating the analysis of public saliency and attitudes toward biodiversity from digital media
Abstract Measuring public attitudes toward wildlife provides crucial insights into human relationships with nature and helps monitor progress toward Global Biodiversity Framework targets. Yet, conducting such assessments at a global scale presents challenges.

ABSTRACT Previous research has established the relationships between motivation, anxiety, teachers’ support, and self‐regulated learning (SRL) in English‐as‐a‐foreign‐language (EFL) learning. Most of the studies, however, have taken a variable‐centered approach in addressing the variable correlations, while learners’ characteristics and variable links ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Abstract As the global protected area (PA) network expands to meet international targets, it is important to assess whether traditional reliance on public land will suffice for projected PA growth or whether other tenures, such as Indigenous or pastoral lands, may increasingly contribute.
