Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1143-1160, April 2026.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

Zhongshan Daxue xuebao. Yixue kexue ban, 1997 摘 要 将钛涂层317L 接骨板植入电子线照射的犬右下颌骨体部, 用透射电镜(TEM)观察相邻骨膜超微 结构变化, 结果显示, 钛涂层317L 接骨板组相邻骨膜超微结构损伤比未喷涂钛层的317L 接骨板对照组轻微。 可能与未喷涂钛层的317L 接骨板所释放出来的毒性较大的C r 、Ni 离子对组织细胞的再损伤有关, 而钛涂层 317 L 接骨板表面呈纯钛相, 不会造成组织细胞超微结构明显损伤。

Mechanisms of Cadmium Tolerance and Detoxification in Sesuvium portulacastrum L. [PDF]
, 2016 近年来由于电镀业、化工业、采矿业蓬勃发展导致大量镉进入水体、大气、土壤环境中，造成严重的镉污染问题，严重威胁生物生命安全。目前镉污染问题已经成为当今世界共同关注的环境问题之一，植物修复法作为一种“绿色”的污染治理手段，由于具有低成本、高净化效率等优点，成为国际上的热点研究领域。目前，植物修复方法的应用越来越广泛，但仍存在很大的局限性，大部分超累积植物生物量少，修复效果不理想，且只能适用于低盐土壤或淡水水域修复，而能够用于盐碱地、湿地及海水水域等盐度较高区域重金属修复的相关植物较少 ...

Guangtongxin yanjiu, 2016 提出了一种基于双微环引起范诺共振效应实现超窄带滤波的微环谐振滤波器,通过泵浦波导和微加热装置使其同时具备有源和可调谐性能。通过耦合模理论,推导了该结构的透射率及超窄带带宽公式,并利用MATALAB软件模拟了在滤波器结构中注入增益对超窄带带宽和滤波器的透过率的影响,以及微环波导的热光效应对滤波器谐振波长的影响。仿真结果表明,在滤波器中注入增益能增大透过率,压缩滤波器的超窄带带宽,且微环波导的热光效应可使谐振波长发生红移或蓝移。

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...
