Inferring alternative ecosystem states with field survey data

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

Conservation Biology, EarlyView.
Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

利用力致分子动力学模拟方法构建剪切流场 [PDF]

, 2009
在传统计算力学的研究领域,利用Fluent等软件实现连续介质流体的模拟,已有很成熟的经验及范例;同时,分子动力学模拟也在其擅长的微观结构分析及预测领域有了长足的发展。但是到目前为止,连续介质力学仍无法和分子动力学方法有机地结合起来。因此,仍无法在分子动力学模拟体系构建理想的(即速度梯度和温度可控的)剪切流场。Grattona与Delgado-Buscalioni等的研究表明,在分子动力学模拟中 ...

Psychometric framework for coexistence with large carnivores

Conservation Biology, EarlyView.
Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

Comparing the Effects of Collaborative and Independent Writing on EFL Learners’ Individual Writing Performance: An Intervention Study

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Collaborative writing has attracted increasing attention in English as a Foreign Language (EFL) instruction due to its potential to enhance learners’ writing competence. However, few studies have examined the comparative effects of collaborative versus independent writing on EFL learners’ individual performance, especially in higher‐order ...

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective

Policy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.

生物分子间二维与三维反应动力学的比较研究 [PDF]

, 2005
生物大分子间反应可分为束缚分子的二维反应和游离分子的三维反应。根据描述二维反应动力学的概率动力学模型,可以设计实验来测定分子间二维反应动力学,例如微管吸吮(Micropipette)、光镊(OpticalTrap)、原子力显微镜(AFM)等技术,但上述方法较复杂,一般只用于实验室研究。基于表面等离子体共振技术的生物传感器是成熟的、商业化测定三维反应动力学方法,该方法简单、易掌握,已经广泛应用于药物的设计、筛选和评价,但难以反映在体条件下大部分生理现象和生物学过程是由二维反应所介导的实际。

Facile and Efficient Synthesis of Dual‐Defect NiFe Layered Double Hydroxides for Enhanced Oxygen Evolution Reaction

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...

Mechanoluminescent Mixed‐Anion Borate Sr2B5O9Cl:Eu for Dynamic Anticounterfeiting

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Mechanoluminescence (ML)—the emission of light in response to mechanical stimuli—offers a direct and visually intuitive route for transducing mechanical information into optical signals. Herein, we report a mixed‐anion strategy to prepare mixed‐anion borate Sr2B5O9Cl:Eu phosphors through a facile, low‐temperature, and ambient‐atmosphere solid ...

Chloride Coordination‐Engineered Fe–NC Catalyst for Directed Singlet Oxygen Generation Through Peroxymonosulfate Activation

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Heteroatom coordination regulation is an effective strategy to enhance Fenton‐like catalysis of single atom catalysts, yet its impact on the local microenvironment of active sites still requires in‐depth investigation. Herein, Cl2–Fe–NC catalysts with axial Cl coordination are prepared.
