Emerging applications of large language models in ecology and conservation science

open access: yesConservation 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

A Study on the Transmitting Mechanism of Financial Risks between Chinese A-share Market and Other Major Asian Stock Markets [PDF]

open access: yes, 2016
随着经济全球化和亚洲一体化进程的深入,中国与亚洲各个国家和地区的合作取得重大突破,中国在亚洲金融市场的话语权不断提高,承担的责任也越来越大,面临来自亚洲的系统性风险越来越不容忽视。深入研究中国A股与亚洲其他主要股市金融风险的传导机制,对中国的经济发展与金融安全以及跨境资产配置都具有非常重要的理论与现实意义。 为了揭示中国A股与亚洲其他主要股市的风险传导机制,本文从风险传导的“外在”和“内在”两个视角进行研究。在“风险传导的外在表现”方面,本文从整体和局部两个层面进行分析。整体层面上 ...

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

Toxicity of BaP exposure during embryonic stage in zebrafish: the mechanisms involved [PDF]

open access: yes, 2016
多环芳烃(PolycyclicAromaticHydrocarbon,PAH)是环境中一类分布广泛的持久性有机污染物。苯并(a)芘(Benzo(a)pyrene,BaP)作为代表性的PAH具有包括神经毒性和生殖毒性在内的多种毒性。截至目前,关于BaP神经毒性的研究大多集中于高浓度或短期的暴露实验,而环境水平浓度下、长期的BaP暴露是否能引起同样的神经毒性则研究得较少;此外,胚胎时期低浓度BaP暴露对成年阶段的神经毒性、生殖毒性效应及其机制研究更为少见。因此本研究以斑马鱼为模式动物,分别进行环境水平浓度 ...

Reconceptualising Motivation as Material‐Semiotic Entanglements: Translanguaging in Graduate TESOL Education

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Multilingual students in Anglophone universities often operate in survival mode. While translanguaging supports learning, critical gaps remain in understanding how translanguaging pedagogies transform and sustain motivation in English‐dominant contexts.

Effects of hexabromocyclododecane (HBCD) on cardiac development in zebrafish embryos (Danio rerio): the mechanisms involved [PDF]

open access: yes, 2015
六溴环十二烷(1,2,5,6,9,10-Hexabromocyclododecane,HBCD)是被运用最广泛的阻燃剂之一,在全球的用量仅次于四溴双酚A和多溴联苯醚。HBCD具有持久性、生物累积性和生物放大效应,因而被定义为持久性有机污染物(persistentorganicpollutants,POPs)。已有研究表明HBCD具有发育毒性、神经毒性、内分泌毒性和生殖毒性,但对心脏发育毒性的研究十分有限,尤其缺乏对心脏发育毒性机制的研究。本研究以斑马鱼和H9C2细胞系为实验模型,采用低浓度HBCD(0 ...

Twelve Years Revisited: Translanguaging as Relational Pedagogy for Sustaining Language Learning Motivation

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

基于ACP的平行发电控制系统

open access: yes智能科学与技术学报, 2019
发电侧控制是整个电网稳定运行的基础,而现有的控制方法已不能满足能源、环境以及人类社会等对发电侧日益增长的需求。为保证发电过程的安全性、高效性和环境友好性,提出了基于 ACP 方法的平行发电控制系统理论。首先,构建与实际物理发电控制系统等价的人工发电控制系统;接下来通过人工发电控制系统的计算实验,选择最优被控对象模型及其对应的控制策略来对物理控制系统的运行进行引导,并对其行为进行评估,使其逐渐趋近人工控制系统;然后,通过发电过程中物理控制系统和人工控制系统的平行执行,确保发电侧的运行稳定性 ...

联邦生态:从联邦数据到联邦智能

open access: yes智能科学与技术学报, 2020
针对大数据时代广泛存在的数据孤岛问题,从整体入手,提出了联邦生态的基本框架,并探讨了其结构和运行机制。联邦生态以数据隐私可控为前提,以区块链技术为支撑,以联邦智能为驱动,借助联邦控制实现数据联邦化,通过联邦管理实现服务联邦化。为打破数据孤岛问题,联邦生态充分发挥了大数据和人工智能的潜力,进而为实现联邦智能提供了一种新的思路。

Molecular mechanism of the role of ROS signaling pathway in the antioxidant properties of TKE2 cells [PDF]

open access: yes, 2016
目的:目前ROS在干细胞生物学中的作用还没有得到充分说明和了解。在过氧化氢(H2O2)诱导的氧化应激条件下,我们比较小鼠角膜上皮祖细胞(TKE2)[1]和成熟的小鼠角膜上皮细胞(MCE)的不同反应,重点研究是角膜干细胞的抗氧化细胞特性及相关机制。 方法:以小鼠角膜上皮祖细胞(TKE2)和成熟的小鼠角膜上皮细胞(MCE)为细胞模型,通过CCK8细胞活性实验检测不同浓度H2O2对小鼠角膜上皮的祖细胞(TKE2)和成熟的小鼠角膜上皮细胞(MCE)的影响。利用H2O2处理细胞24小时后 ...
