Effects of hexabromocyclododecane (HBCD) on cardiac development in zebrafish embryos (Danio rerio): the mechanisms involved [PDF]
, 2015 六溴环十二烷（1,2,5,6,9,10-Hexabromocyclododecane，HBCD）是被运用最广泛的阻燃剂之一，在全球的用量仅次于四溴双酚A和多溴联苯醚。HBCD具有持久性、生物累积性和生物放大效应，因而被定义为持久性有机污染物（persistentorganicpollutants，POPs）。已有研究表明HBCD具有发育毒性、神经毒性、内分泌毒性和生殖毒性，但对心脏发育毒性的研究十分有限，尤其缺乏对心脏发育毒性机制的研究。本研究以斑马鱼和H9C2细胞系为实验模型，采用低浓度HBCD（0 ...

Environmental niche models improve species identification in DNA barcoding
Methods in Ecology and Evolution, Volume 15, Issue 12, Page 2343-2358, December 2024.Abstract Recent advances in DNA barcoding have immeasurably advanced global biodiversity research in the last two decades. However, inherent limitations in barcode sequences, such as hybridization, introgression or incomplete lineage sorting can lead to misidentifications when relying solely on barcode sequences.

Gaoya dianqi, 2020 为提升高压断路器机械故障诊断算法故障诊断效率与精度,文中提出一种基于Relief F算法和灰色关联分析的故障诊断方法。首先,从高压断路器分合闸线圈电流中提取20种特征量,采用Relief F算法计算所有特征权重;然后,使用基于重要特征构成的故障样本建立灰色关联分析模型的参考序列,并归一化对应特征权重向量;最后,计算参考序列与待测序列之间的关联度值确定待测样本故障类型。通过实例分析验证结果表明,文中提出的诊断方法能准确诊断高压断路器机械故障,同时引入Relief F算法降低诊断模型复杂度并提高故障诊断效率,

Ecological Studies of Marine Virus and its Viral Lysate [PDF]
, 2015 病毒是海洋生态系统中数量最多、多样性最为丰富的一类生命形式，具有极为重要的生态地位。为了深入认识海洋浮游病毒及其裂解浮游细菌释放的裂解产物的生态效应，本论文首先研究了西太平洋典型寡营养海区的浮游病毒对浮游细菌的致死效应；接着研究病毒裂解产物如何在不同营养水平（寡营养和富营养）特征的海洋水体中影响浮游细菌的生长、群落组成等生态特性。此外，本论文以海洋生态系统中一类生态地位非常重要的浮游细菌-玫瑰杆菌（Roseobacter）为研究对象，对其裂解性病毒进行了分离纯化和鉴定 ...

Integrative Conservation, Volume 3, Issue 3, Page 257-270, September 2024.Natural training enclosure design schematic. We selected 12 sika deer including six adults and six sub‐adults. Key considerations in the design of the natural training were to divide the training spatial ground into two parts (30 × 30 m small areas for isolation of new individuals and large areas measuring 200 × 600 m for free walking), and the ...
