Otolith Morphology of Small Yellow Croaker (Larimichthys polyactis)in Yangtze River Estuary and the Application in Biology Study [PDF]
, 2016 耳石为硬骨鱼类内耳中的钙化结构，主要起到听觉及平衡鱼类身体的作用。目前耳石形态学已成为国内外鱼类学研究的热点，涉及鱼类年龄与生长、种群划分、群体识别、生活史反演等多个领域。本研究以长江口小黄鱼（Larimichthyspolyactis）为研究对象，研究耳石形态与体长、体质量的关系，探讨耳石生长与小黄鱼特殊生长阶段的关系，且从生物学及耳石形态学角度综合探讨小黄鱼春季群体及秋季群体间的差异，并就耳石形态在两个不同生态群体间的识别作用及年龄鉴定作用进行初步探究，旨在丰富小黄鱼耳石形态学研究 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

, 2009 银鲫(Carassius auratus gibelio Bloch)由于其独特的遗传背景和繁殖方式而成为研究进化遗传学和选择育种的一个独特的模式生物。到目前为止,我们对新疆额尔齐斯河水系银鲫群体的多样性状况一直知之甚少。为了更好地了解额尔齐斯河水系银鲫群体的克隆多样性状况,本研究中,我们采集了来自新疆额尔齐斯河水系的4个鲫鱼群体。通过流式细胞术分析血细胞样品,结果证实这些鲫鱼均为三倍体银鲫。通过血清转铁蛋白电泳表型分析,我们从这些银鲫群体中鉴定出总共8个不同的克隆。在这些鉴定的克隆中,有4个克隆 ...

A Tale of Two Programs? Stigma and Administrative Burdens in CHIP and Medicaid
World Medical &Health Policy, Volume 18, Issue 1, March 2026.ABSTRACT One contributing factor to undersubscriptions is administrative burdens. To explore whether program stigma affects attitudes about administrative burdens, a survey (N = 2204) was fielded to assess differences in attitudes about seven policies decreasing administrative burdens and two policies increasing administrative burdens.
