Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

浙江大学学报. 医学版过继细胞输注（ACT）疗法在血液系统肿瘤的治疗中疗效显著，但在实体瘤的治疗中存在归巢不良、免疫抑制及潜在毒副作用等问题。近年来，不同尺寸的生物材料（如纳米粒、微球/微贴片和水凝胶）在细胞体外工程化、在体递送及肿瘤微环境调控等方面展现出独特优势。纳米粒可用于基因递送、人工抗原呈递系统构建和免疫微环境重塑；微球和微贴片增强了免疫细胞的扩增、靶向激活及局部滞留；水凝胶则通过在体基因工程化、三维培养支持和细胞因子共递送等方式提升ACT疗效。本文综述了ACT中不同尺寸生物材料在提升递送效率 ...

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Conservation Biology, EarlyView.Abstract In the western United States, conservation practitioners are increasingly working with private landowners to restore habitat for North American beavers (Castor canadensis) and to use nonlethal mitigation techniques when beavers damage crops and infrastructure.

Haiyang yu huzhao在南海海盆区分离得到一株侵染海洋聚球藻的噬藻体QB2，分析表明其基因组全长为171 898 bp，GC含量为41.49%。在噬藻体QB2基因组中检测到212个开放阅读框（ORFs）和7个tRNA基因。所预测到的ORFs根据功能可分为病毒粒子结构模块、DNA复制与调控模块、包装模块和辅助代谢功能模块。其携带有与光合作用、碳代谢、磷代谢、能量获取和应激调节等相关的20个辅助代谢基因，可能在调控噬藻体侵染过程中宿主的能量代谢方面发挥关键作用 ...

Dianci bileiqi, 2022 特高压变压器中性点经小电抗接地在降低线路单相短路电流的同时，提高了中性点的过电压水平，为中性点配置合适的过电压保护十分重要。本研究运用EMTP对华东某特高压变电站进行等值建模，对变压器中性点串接多个阻值小电抗后限制短路电流能力进行量化分析，从而确定中性点小电抗的最佳取值。根据工程实际，变压器中性点串接小电抗后，在中性点并联氧化锌避雷器和放电间隙可以提供一定的过电压保护。由于避雷器动作后残压过高，会使放电间隙击穿放电，考虑用可控避雷器替代氧化锌避雷器以实现最佳的绝缘配合。

Basic study on the current signals caused by one line grounding fault in distribution lines consisting of neutral system with grounding reactors [PDF]
, 1995 There is ground fault as one of the most impotant problems in distribution lines. It is urgently necessary to establish the technology to distinguish the causes of their faults for preventing them beforehand or finding their locations at the early stages.
