Salinity stress in the black‐chinned tilapia Sarotherodon melanotheron

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 341, Issue 5, Page 553-562, June 2024.
Abstract Physiological and morphological acclimation capacities of black‐chinned tilapia, Sarotherodon melanotheron were studied from fish to gill cell level when fish are maintained in freshwater, seawater, and hypersaline conditions. Fish osmoregulatory capacity, gill ionocyte morphology, osmo‐respiratory compromise, O2 consumption rate, branchial ...

Fish gill surface area can keep pace with metabolic oxygen requirements across body mass and temperature

open access: yesFunctional Ecology, Volume 38, Issue 4, Page 755-764, April 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate warming is driving the maximum attainable size of many fish species to decrease, yet the mechanisms underlying this ‘shrinking’ phenomenon are not well understood. The gill oxygen limitation (GOL) hypothesis is perhaps the most prominent mechanistic proposition,

An Ultra-Low-Jitter 22.8-GHz Ring-LC-Hybrid Injection-Locked Clock Multiplier With a Multiplication Factor of 114

open access: yes, 2019
An ultra-low-jitter, ring-LC-hybrid injection-locked clock multiplier (ILCM) is presented to achieve a high multiplication factor of 114. The proposed hybrid ILCM cascades a ring-type voltage-controlled oscillator (VCO)-based ILCM and an LC-type VCO ...

开孔金属腔屏蔽系数快速算法宽频适用性研究

open access: yes四川大学学报. 自然科学版, 2013
本文研究了TLM、ILCM、Modal-MOM三种模型计算平面波照射下开孔矩形金属腔宽频带内屏蔽系数的适用性.通过比较这三种模型在0.5~3GHz范围腔体中心点处屏蔽系数的计算结果,并与CST模拟结果进行对比,发现Modal-MOM方法适合用于宽频段屏蔽系数的计算,但在高频时预测出的谐振点有明显频偏.TLM不适用于高频(电尺寸较大孔缝)计算,而ILCM方法不适用于较高频率情况和正方形孔缝的计算,且整体计算结果偏差较大.这些方法的适用范围在工程应用方面具有很好的指导意义.

快速算法用于带孔缝金属腔屏蔽系数计算的比较研究

open access: yes四川大学学报. 自然科学版, 2014
本文比较了TLM、ILCM和M-MOM三种快速算法在斜入射波和多面开孔情况下计算金属腔屏蔽系数(SE)的适用性,发现M-MOM在各种情况下的计算结果最为准确,ILCM无法计算多面开缝情况,而TLM不适用于电大尺寸情况.本文还研究了电磁波的入射角和极化角、孔缝长边、腔体内观测点位置及相对面孔缝位置等参数对SE的影响.结果表明单面开缝时SE随方位角、极化角增大而增大,随仰角增大而减小,而相邻面开缝的SE则由方位角和腔体尺寸决定.当孔缝长度接近或大于半波长时,SE不再随长度的增大而减小.腔体内观测点位置不同 ...
