基于移动窗解卷积法的2011年日本东北 MW9.0大地震场地非线性时变识别

open access: yesDizhen xuebao, 2022
利用模拟记录和2011年日本东北MW9.0大地震观测记录分析了基于移动窗解卷积法识别场地非线性时变特征的可行性,并与移动窗谱比法的结果进行了对比分析。研究表明:基于移动窗解卷积法可以较好地揭示场地非线性随地震动水平的变化过程,识别非线性发生的阈值、非线性变化程度及强震动后的恢复程度;与移动窗谱比法相比,移动窗解卷积法更容易获得较为稳定的土体非线性时变过程,但对于存在强阻抗比的浅表层土体,移动窗谱比法可以获得更准确的非线性程度。对2011年日本东北MW9.0大地震中8个KiK ...

基于CFD/CSD耦合的间隙非线性气动弹性数值研究

open access: yes, 2021
在飞行器操纵面的铰链处往往存在间隙非线性,会导致在低于线性颤振速度下就出现了流固耦合振动,如极限环振荡。对于实际工程应用,结构模型往往是三维的,流动也是复杂的,会存在跨音速流动、粘性效应等气动非线性因素。建立基于计算流体力学/计算结构力学(CFD/CSD)耦合的间隙非线性气动弹性分析方法(JSV, 494 (2021), 115896)。流场网格变形采用径向基函数方法,减缩结构运动方程的建立采用虚拟质量法,间隙非线性切换点的捕捉采用二分法,通过二分法确定的自适应时间步长要返回到CFD程序 ...

Physical Model for Quantitative Organization Design on Mechanical Performance of Nanotwin Unit in Face‐Centered Cubic Metal

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Arranging functional units into a specific organization is a practical structural strategy for achieving fabulous performance, known as the functional unit and organization (FUO) paradigm. This paradigm offers a concise shortcut to establishing structure–performance relationships.

“The Land's Been Queer Longer Than the Colonizers Have Been Here. Hiy Hiy.” Impacts of Anti‐Queer and Trans Policies and Resistance Through Art, Queer Joy, and Worldmaking Among Youth

open access: yesSexuality, Gender &Policy, Volume 9, Issue 4, November 2026.
ABSTRACT This study explores how 2SLGBTQ+ youth in Alberta, Canada—the country's most Conservative province—mobilize queer joy as a form of resistance amid rising anti‐queer and anti‐trans policies under a settler colonial, cisheteropatriarchal regime. Drawing from youth‐produced collages, we demonstrate that this visual arts‐based participatory method

Partisanship, Deservingness, and the Attitudinal Policy Feedback Process for Social Policy

open access: yesPolicy Studies Journal, Volume 54, Issue 4, November 2026.
ABSTRACT In an era of identity‐based partisan polarization, we examine whether social policies can still generate positive attitudinal feedback among beneficiaries. Drawing on nationally representative survey data, we demonstrate that partisanship conditions the policy feedback process through divergent perceptions of group deservingness.

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention

open access: yesPolicy Studies Journal, Volume 54, Issue 4, November 2026.
ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.

Laser‐Induced Graphene/AuNPs‐Gated OECT Biosensor for Sensitive Detection of PD‐L1‐Positive Exosomes Associated With Non‐Small Cell Lung Cancer

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lung cancer remains a major cause of cancer‐related mortality worldwide, and non‐small cell lung cancer (NSCLC) accounts for the largest proportion of diagnosed lung cancer cases. Exosomal programmed death‐ligand 1 (PD‐L1) has attracted increasing attention as a potential liquid‐biopsy biomarker associated with tumor immune regulation; however,

Removal Thickness Prediction and Process‐Window Identification in Laser Cleaning of Multilayer Aerospace Coatings

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Precise control of removal thickness is critical for laser cleaning of multilayer aerospace coatings particularly for selective removal without substrate exposure. However, the process response becomes highly sensitive near coating interfaces, making reliable parameter selection difficult.

Behavioral interventions to reduce demand for threatened freshwater turtles as pets

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...
