Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

Conservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

How Different Patterns of Policy Attention Drive Policy Diffusion: Evidence From China's River Chief System

Policy Studies Journal, EarlyView.
ABSTRACT Despite extensive research on policy diffusion, the ways in which policy attention influences this process remain underexplored. This study addressed this gap by distinguishing between three types of policy attention—political speeches, policy issuance and field visits—and investigating their differential impacts when delivered by central and ...

Electrospinning‐Driven IGZO Nanofiber Phototransistors Bridging Adaptive Processing and Recognition Learning

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The development of neuromorphic electronics with visual perception and adaptive capability is highly desirable for advancing artificial vision systems. Herein, we have demonstrated a dual‐plasticity adaptive phototransistor based on IGZO nanofibers that exhibits the perception and dynamic adaptation behavior of rod and cone cells to varying ...

Solutionism for the Many, Regulation for the Few: How Online Media Bundles the Policies on the Future of Work in Indonesia

Review of Policy Research, Volume 43, Issue 2, March 2026.
ABSTRACT The future of work (FoW), that is, how new technologies from automation to artificial intelligence affect the workplace, has become such a salient topic that its framing matters for the evolution of important policy areas from social protection to market and labor regulation.

Tantalum‐Driven Interfacial Reconstruction Enables Ultra‐Low Contact Resistance in TiAlTa/Au GaN HEMTs

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The transformative potential of gallium nitride high electron mobility transistors (GaN HEMTs) in advancing carbon‐neutral power systems remains bottlenecked by contact resistance (Rc) at the metal–semiconductor (M‐S) interface, a critical determinant of switching losses and frequency response.

Bifunctional Competitive Structure of Biomass Carbon‐Derived Metacomposites for Tunable ε′‐Near‐Zero and ε′‐Negative Responses

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...

Informal Digital Learning of English (IDLE) as Form‐Focused and Meaning‐Focused Activities: Refining its Measurement and Examining its Predictive Role in L2 Achievement and Confidence

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 393-408, February 2026.
ABSTRACT Acknowledging the limitations of existing measurement instruments in adequately capturing the distinct cognitive processes (e.g., form‐focused vs. meaning‐focused) involved in informal digital learning of English (IDLE), this paper asserts a pressing need to develop and validate robust instruments that measure form‐focused and meaning‐focused ...

岔巴沟流域地貌形态分形特征量化研究

Shuitu Baochi Xuebao, 2004
分形理论和方法为地貌学的非线性研究开辟了新的思路。本文基于分形基本理论和GIS技术,对地处黄土高原丘陵沟壑区第一副区的岔巴沟流域地貌形态分形特征进行了量化研究,提出了流域地貌形态特征分形信息维数的计算模型和方法,并依此获得了岔巴沟流域及各支流域的地貌形态特征分形信息维数。研究表明,岔巴沟流域及各支流域的地貌形态特征分形信息维数均小于1,且与流域面积保持很强的正相关;分形信息维数揭示了流域地貌形态复杂本质的量化特征,为黄土高原小流域侵蚀产沙预报模型中宏观地貌形态因子的量化提供了新的思路和方法。

不同母质发育紫色土团粒结构的分形特征研究

Shuitu Baochi Xuebao, 2003
运用分形模型对不同紫色母质发育的土壤团聚体特征进行研究,结果表明:土壤团聚体粒径分布的分形维数与土壤团聚体结构破坏率存在极显著正相关(r=0.961**,n=8),与>0.25mm水稳性团聚体含量存在极显著负相关(r=-0.958**,n=8);不同紫色母质发育的土壤团聚体粒径分布的分形维数存在差异,棕紫泥土壤团聚体粒径分布的分形维数最高,暗紫泥土壤团聚体粒径分布的分形维数最低。土壤团聚体粒径分布的分形维数是评价土壤物理肥力和土壤抗蚀性的一个新指标。
