Laser &Photonics Reviews, EarlyView.This work introduces two types of bound states in the continuum (BICs) and their merging in a waveguide‐resonator system, which significantly enhances the quality factor (Q$Q$). Benefiting from the high‐Q$Q$ characteristics of quasi‐BICs, a sensitivity‐tunable complex permittivity sensor is developed based on this system, achieving improvements of 93 ...

, 2012 通过比较D系三倍体银鲫(Carassius auratus gibelio Bloch)与异源四倍体银鲫,我们发现异源四倍体的外周血与精巢组织跟三倍体银鲫存在明显差异。HE染色结果表明,异源四倍体银鲫外周血红细胞有明显的分裂倾向。利用流式细胞术对D系三倍体银鲫与异源四倍体银鲫外周血的DNA直方图进行比较,结果表明异源四倍体外周血的DNA直方图有两个主峰。此外,我们观察到异源四倍体银鲫精巢的三种类型,其中Ⅰ型精巢可以产生正常精子,Ⅱ型可观察到精小囊结构,但不能产生精子,Ⅲ型精巢未发育出精小囊结构 ...

Haiyang yu huzhao伪雄鱼是由雌鱼性逆转而成的生理性雄鱼，在全雌鱼苗种的规模化繁育过程中有着至关重要的作用，但国内外对其精子活力的研究较少。为研究黄姑鱼伪雄鱼繁殖期精子活力及环境因子对其活力的影响，利用计算机辅助精子活力分析系统(CASA)对伪雄鱼的精子密度、运动率、寿命和运动速度等指标进行测定；并且设置不同的温度和pH梯度组，探究不同环境因子对伪雄鱼精子活力的影响。结果显示，伪雄鱼精子密度为(2.60~2.24)×1010个/mL；在繁殖期内，伪雄鱼精子密度呈逐渐下降的趋势，且在排精中期和晚期 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Metal‐doped carbon‐based nanomaterials (M‐CNM) play a strategically significant role in next‐generation precision antibacterial and antitumor therapies, as they integrate synergistic photothermal ablation, catalytic reactive oxygen species (ROS) generation, and multimodal imaging capabilities. However, their clinical translation is hindered by
