Review of Policy Research, Volume 43, Issue 6, November 2026.ABSTRACT Nature conservation conflicts increasingly extend beyond ecological objectives to disputes over decision‐making legitimacy, institutional authority, and competing understandings of landscape and expertise. This article examines the conflict over the proposed designation of Křivoklátsko as a national park in the Czech Republic between 2021 and ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Surface‐enhanced Raman scattering (SERS) has emerged as a highly sensitive and specific technique for tumor imaging, owing to its narrow spectral features, resistance to photobleaching, and capability for multiplexed detection. However, its clinical translation remains limited by poor tissue penetration and the absence of intrinsic anatomical ...

Light‐Synergistic Enhanced Synaptic Devices Toward Superadditive In‐Sensor Computing
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Conventional neuromorphic devices face challenges in achieving efficient integration of light sensing and synaptic computation because of structural and material limitations. In this work, we developed an indium‐tin‐zinc oxide/transparent gelatin electrolyte synaptic transistor incorporating rare metal indium.

四川大学学报. 自然科学版, 2008 我们提出了基于"认识"事物的人脸识别.以同类样本全体的连续性规律为基本出发点把人脸识别看成人脸"认识"的问题而不是人脸分类划分,与以"最佳划分"为目标的传统统计模式识别相比,本文的方法更接近于人类"认识"事物的特性.同一人脸的分布在低维空间中具有一定的类聚性而不同人脸的覆盖范围相互交织.随着空间维数增加,同类样本内聚性减弱,不同类样本互斥性增强;空间维数继续增加,同类样本内聚性与不同类样本互斥性反而都会减弱.将待识别人脸在某一空间进行覆盖范围的识别.若属于多个侯选人脸覆盖范围 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The use of Ti6Al4V alloy in dental implantation is constrained by its high elastic modulus and biological inertness, which lead to delayed osseointegration and a high failure risk. Additionally, its chemical incompatibility with hydroxyapatite (HA) impedes the development of stable bioactive composites.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Developing rapid, precise gas sensors for Listeria monocytogenes (LM) biomarker detection faces challenges due to suboptimal gas‐solid interactions. Herein, we report the rational synthesis of amino‐functionalized mesoporous SiO2 hollow nano‐doughnuts (MS‐2‐NH2‐2) via modification with (3‐aminopropyl) trimethoxysilane (AAPTMS), which enables ...
