Tracing change in the public perception of plants: insights from archives and social media in China
As urbanization accelerates, historic gardens serve as vital cultural treasures that offer spiritual and cultural support to the public. This study proposes an innovative approach that merges historical records from the Qing Dynasty with contemporary social media data to explore changes in public perceptions of these gardens.

黄姑鱼
黄姑鱼是我国重要的海水经济鱼类,随着养殖规模逐渐扩大,对其优良养殖种质的需求也愈加迫切。不饱和脂肪酸含量作为重要的营养品质性状,受到育种研究学者的广泛关注。测定了179尾黄姑鱼选育群体后代的肌肉脂肪酸组成,获得了以n-3长链多不饱和脂肪酸相对含量等表型性状,对这179尾个体开展全基因组重测序,经过质控、变异检测后获得2 940 251个高质量单核苷酸多态性(SNP)位点;基于混合线性模型对脂肪酸表型开展全基因组关联分析,定位到19个显著相关的SNP位点,并鉴别到27个候选基因 ...

ABSTRACT This study investigates how ordinary Taiwanese netizens perform linguistic authority by policing others’ use of Mainland Chinese expressions in everyday online interactions not originally intended to be political and how such policing is subsequently supported, resisted, or (de)legitimized in the context of Taiwan–China relations.

ABSTRACT Infrared (IR) stealth is crucial for improving the survivability of equipment. The growing demand for service in marine environments poses new challenges to the composition and structural design of existing IR stealth coatings. This study first investigates the effects of NaCl/water vapor corrosion on the IR stealth performance of GH3536 and a

目前虽未见海水淡化工程对其所在海域的生态环境造成严重破坏的相关报道,但由于浓盐水具有高盐度、高温的特点,且含有铝、重金属和杀菌剂余氯,会明显抑制部分浮游动植物的生长;而在浓盐水排放的相关海域中,鱼类丰度和物种丰富度有所提高。因此,需要进一步研究浓盐水排放对海洋生态环境的影响。综述了国内外海水淡化产生的浓盐水的排放现状和管理要求,重点分析了海水淡化工程浓盐水排放对海洋生态环境造成的影响,并提出减缓影响的相应对策与建议。通过梳理现有排放方式,发现通过优化浓盐水排放口设计,采用混合排放技术 ...

ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.

Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

[[abstract]]在過去的年代中,想要獲得海洋水文或流況的方法,唯有使用測量儀器進行現場觀測一途。但是現場觀測由於受到儀器、技術與天候等等的限制,往往無法同時間對大範圍海域進行水文與海流的觀測。我們利用數個涵蓋不同區域以及具有不同水平解析度的數值模式,針對臺灣周遭海域的水文與流況進行模擬研究。經過與現有的觀測資料驗證比較,成功地重建了臺灣周遭海域的海流與水文環境。這樣的研究成果在我國反潛作戰使用或在其他軍事應用方面皆能提供正確的、有效的海洋戰場環境資訊 ...

Neural network modeling of salinity in Qiantang Estuary(钱塘江河口盐度的神经网络模拟)
盐水入侵会对潮汐河口饮用水源地产生影响,河口盐度的合理预测对饮用水源地取水安全和水库泄水抑咸调度有重要意义.以上游流量和下游潮差为控制条件,建立模拟钱塘江河口盐度变化情况的神经网络模型.首先对输入数据作归一化处理,利用上半年观测数据对模型进行反复训练,进而后报下半年盐度.模型输出数据反归一化所得到的结果与实测盐度数据比较,两者较为一致.表明基于河口盐度与上游流量和下游潮差间映射关系所建立的神经网络模型可有效地模拟潮汐河口的盐度变化.利用神经网络方法模拟了上游流量变化条件下钱塘江河口某测站的氯化物浓度 ...

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).
