Mechanoluminescent Mixed‐Anion Borate Sr2B5O9Cl:Eu for Dynamic Anticounterfeiting
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Mechanoluminescence (ML)—the emission of light in response to mechanical stimuli—offers a direct and visually intuitive route for transducing mechanical information into optical signals. Herein, we report a mixed‐anion strategy to prepare mixed‐anion borate Sr2B5O9Cl:Eu phosphors through a facile, low‐temperature, and ambient‐atmosphere solid ...

基于红外相机对额仁淖尔苏木盘羊(Ovis ammon)生存现状的研究
野生动物学报, 2015 自2012年12月～2013年12月,利用红外相机技术及样线法首次对额仁淖尔苏木的盘羊生存现状进行研究。结果表明:该种群由3只成体(2♂1♀)2只亚成体(1♂1♀)和1只幼体(1♂)组成; 平均每台红外相机的拍摄率为38%; 以拍摄率作为衡量盘羊活动频率的标准,冬季盘羊的活动频率达到高峰,春季和夏季较为稳定,秋季降到最低。盘羊对水源点的利用强度占2%,肉食性野生动物占21%,家畜占77%; 盘羊对隐蔽度的要求较高,占总生境的59%。

Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

降钙素原与C反应蛋白对神经外科重症患者呼吸机相关性肺炎的诊断价值
Zhongguo shiyan zhenduanxue, 2021 呼吸机相关性肺炎（VAP）常发生于重症监护病房[1]。文献报道VAP在重症患者中均有较高的发病率和死亡率[2-3]。早期诊断VAP对提高神经外科重症患者的预后具有重要意义。本研究测定了吉林大学中日联谊医院80例神经外科重症监护室（ICU）的VAP患者血清C反应蛋白（CRP）和降钙素原（PCT）的水平,观察这两项指标对VAP的早期诊断价值。
