, 2007 电解沉积方法制备的纳米晶镍经650℃退火处理后，晶粒发生了长大，在晶内沿特定晶面析出了第二相颗粒，样品的拉伸断口为沿晶断口。利用EDS和EBSD对这种第二相析出物进行的成份分析和结构／取向分析表明：这种第二相颗粒是NiS2颗粒，其晶格取向与基体镍保持一致。NiS2颗粒沿基体镍的（001 ...

微藻油脂合成的转录调控研究进展Advances in transcriptional regulation of lipid synthesis in microalgae
Zhongguo youzhi生物燃料是传统化石燃料的理想替代品，微藻是生产生物燃料的优良原料,通过对微藻油脂合成和调控的了解，能够有效提高微藻生产生物柴油的效率。转录因子是一种具有特殊功能结构、行使调控基因表达功能的蛋白质分子，在复杂的油脂合成代谢过程中，转录因子能对代谢过程中多个酶系进行集体调控，从而促进藻细胞中油脂积累。从微藻油脂的合成途径出发，简要介绍了合成途径中的关键酶，重点综述了bZIP、MYB、Dof、bHLH转录因子对于微藻油脂合成的调控影响。微藻油脂合成涉及多个亚细胞单位的多条途径，是一个十分复杂的代谢网络过程 ...

Journal of Analytical Psychology, EarlyView.Abstract Written as a letter to my 28‐year‐old self, this paper explores the development of my engagement with cultural complexes. On August 18, 2009, I finished a chapter applying cultural complexes to a history of China, complete with elaborate charts that seemed to confirm a process by which cultural complexes are formed, and how China’s then recent

, 2002 发展了一种毛细管色谱切割-反吹方法分析汽油中的芳烃。利用OV-2330强极性毛细管预柱将芳烃保留至n-C10之后，并反吹到非极性毛细管柱中按沸点详细分离分析。从预柱先流出的组伊从分析柱流出的组分都先后进入同一检测器中，因此可用响应因子校正的归一化方法定量分析汽油中的芳烃。该方法在15min内完成汽油中苯至C10芳烃的分析，结果的重复精度误差≤3%（RSD），切割误差±5s时对分析结果的影响≤4%（RSD ...

Jungian Approaches to Sound and Music: A Critical Review of Margaret Tilly’s Music Therapy Practice
Journal of Analytical Psychology, EarlyView.Abstract This paper is grounded in the 1956 meeting between Carl Gustav Jung and the music therapist Margaret Tilly, as documented in William McGuire’s C. G. Jung Speaking: Interviews and Encounters (1977). It draws on both published and archival primary sources related to Tilly, examining them with particular attention to treatment style ...

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Emerging applications of large language models in ecology and conservation science
Conservation Biology, EarlyView.Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature
