为了改善传统钢框筒结构抗震性能差和震后不易修复的缺陷,在裙梁跨中设置可更换双槽钢耗能梁段,提出含双槽钢腹板螺栓连接的钢框筒结构(SFT-WSL)。首先介绍了SFT-WSL构件的设计要点;然后根据结构的受力变形特点得到结构的滞回耗能修正系数,用以考虑双槽钢腹板螺栓连接变形的贡献,可用于基于性能的结构塑性设计;其后提出了结构的有限元建模方法,通过子结构试验结果验证了有限元模型的准确性;最后设计了一个30层的SFT-WSL算例,并对该结构算例进行了弹塑性分析和基于增量动力分析(IDA)的结构抗倒塌易损性分析 ...

Integrating migratory connectivity data into the conservation of Australian sharks and rays
Abstract Understanding migratory connectivity is important for conserving highly mobile marine species facing escalating threats. Establishing baseline information on migratory connectivity is necessary for identifying species and regions requiring transboundary cooperation for their conservation.

Lai-Massey结构(L-M结构)是分组密码中一类重要的整体结构,任意轮的L-M结构都不具备伪随机性.Vaudenay通过对L-M结构做一个简单变换,使得3轮L-M变体结构具备伪随机性,并在FOX分组密码的设计中采用此变体结构.该文针对基于L-M变体结构来设计可调分组密码进行了研究.通过在L-M变体结构的不同位置异或可调因子(tweak),分析了3轮基于L-M变体结构设计可调分组密码的可行性.对3轮结构提出了攻击的方法.

A Systematic Scoping Review of Self‐Regulated Learning With AI in Language Education
ABSTRACT The rapid development of artificial intelligence (AI) technology has brought new opportunities for second/foreign language (L2) education while also raising concerns about the use of AI tools. This systematic scoping review provides a snapshot of the current state of research situated at the intersection of self‐regulated learning (SRL) and AI

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

ABSTRACT This study examines multilingual practices in research interviews, focusing on English lexical insertions in Chinese‐language research interviews with teachers of Chinese in Australian secondary schools, and treating these code‐switches as analytically meaningful rather than incidental.

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 ...

在风电机组预应力钢-混凝土混合结构塔筒中,转接结构是用于连接上部钢塔段与下部混凝土塔段的过渡结构,其受力复杂,采用传统的钢筋混凝土结构形式容易产生裂缝甚至发生破坏。提出了一种中空夹层钢管混凝土转接结构,并进行了4个中空夹层钢管混凝土转接结构试件及1个钢筋混凝土转接结构对比试件的轴压试验。结合有限元及理论分析揭示了中空夹层钢管混凝土转接结构的承载能力及隔板、栓钉等因素对其受力性能的影响。结果表明:在相同用钢量下,中空夹层钢管混凝土结构形式显著提高了转接结构的承载能力及变形能力 ...

ABSTRACT In English medium instruction (EMI), students face cognitive and emotional demands in second language (L2) communication, which may hamper their motivation and willingness to communicate (WTC). Adopting a mixed‐methods design, this study explores how growth mindsets affected student motivation (e.g., ideal L2 self and ideal disciplinary self ...
