RP-3高温氧化初始阶段反应机理的ReaxFF MD模拟

, 2016
本文采用ReaxFFMD方法对一种较新的RP-3四组分替代燃料模型的高温氧化过程进行了研究。利用作者所在课题组研发的独特分析工具VARxMD,对燃烧过程中主要物种（燃料分子、O_2、C_2H_4、·CH_3）随时间和温度的演变规律及其化学反应进行了系统分析。ReaxFFMD模拟得到的燃料和氧气消耗量、乙烯和甲基自由基的生成量与相同温度和初始压力条件下CHEMKIN的计算结果处于同一量级,同时获得了详细的物质结构信息和反应列表。进一步对模拟得到的反应机理形式进行观察后发现 ...

Comparative species distribution model framework for marine conservation and its application to loggerhead turtles in the Mediterranean

Conservation Biology, EarlyView.
Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

Using the capabilities approach to achieve people‐centered conservation

Conservation Biology, EarlyView.
Abstract Top‐down interventions carried out by state and nonstate institutions to conserve biodiversity and improve the lives of forest‐proximate people (FPP) in the Global South tend to reflect economistic understandings of human well‐being. More progressive and people‐centered conservation projects are guided by normative visions of how the world ...

Artificial Intelligence for Language Learning: A Systematic Review of its Design, Theoretical Foundations, Implementation, and Impact

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Although the use of AI technologies (e.g., chatbots and automated writing evaluations (AWE)) has gained considerable attention in language learning fields in recent years, how AI technologies have been designed and implemented in language learning education, as well as their effectiveness, is understudied.

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

International 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.

Unraveling Student Anxiety in EFL Classrooms in China: The Roles of the Classroom Environment and Control–Value Appraisals

International Journal of Applied Linguistics, EarlyView.
ABSTRACT In this study, control–value theory (CVT) was used to investigate how students’ perceptions of the classroom environment shape their anxiety in the context of English as a foreign language (EFL) learning through the mediating effects of control and intrinsic value appraisals.

Accountability in Government Use of AI: Citizen Concerns and Preferences

Public Administration, EarlyView.
ABSTRACT Government adoption of AI opens the “pandora's box” of accountability, a core aspect of public value. Despite the centrality of governmental AI accountability, citizens' concerns and preferences in holding governments accountable for AI usage remain poorly understood.

Running With Scissors? Integrating GPT Models Into Public Policy Research

Policy Studies Journal, EarlyView.
ABSTRACT The integration of large language models (LLMs) into public policy research presents both exciting opportunities and methodological challenges. This research note explores how OpenAI's GPT can be used to semi‐automate the annotation of legislative testimony within the Advocacy Coalition Framework, focusing on emotion‐belief dyads.
