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 ...

Rare 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,

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Spent automotive exhaust catalysts represent the largest secondary resource of palladium (Pd), and their efficient recovery is essential to support the sustainability of Pd‐related industries. Inspired by supramolecular chemistry, a novel calixarene derivative, 5,11,17,23‐tetra‐tert‐butyl‐25,27‐bis[(N′‐hydroxyacetimidamide)ethoxy]‐26,28 ...

Toward a Concept of ASEAN Autonomy: Actors, Entities, and Regional Space
Asian Politics &Policy, Volume 18, Issue 4, October 2026.ABSTRACT Widely discussed across disciplines, autonomy is often used in ASEAN studies to describe what actors associated with ASEAN seek. Yet its meaning remains underspecified and differs from dominant approaches of international organization autonomy.

Shuitu Baochi Xuebao, 2001 湿地土壤养分是时空连续的变异体,不论尺度大小均具有高度的空间异质性.湿地土壤养分变量属于区域化变量,同时具有随机性和结构性,仅运用经典的Fister统计方法已经不能满足土壤空间异质性研究的需要.地统计学是近几十年发展起来的一门新的空间分析方法,其变异函数则适合于定量研究区域化变量空间结构变异特征,能够全面反映区域化变量的结构性.作者在前人的工作基础上意欲用地统计学的区域化变量理论和变异函数对湿地土壤养分的空间异质性进行定量研究,并对其研究方法进行了构想.＃

Shuitu Baochi Xuebao, 2020 研究黄土高原侵蚀环境下林地开垦后坡面土壤养分空间分布状况，确立林地开垦后侵蚀驱动的坡地土壤养分空间变异特征。以黄土高原丘陵区子午岭林地和开垦28年的侵蚀坡面为研究对象，分析土壤主要性质和养分含量的变化情况，运用经典统计学和地统计法分析坡面土壤基本性质和养分空间分布规律。林地开垦后坡面土壤pH增加了0.24个单位，有机质、全氮、全磷和铵态氮、硝态氮、速效磷和速效钾分别降低了13.77，1.14，0.10 g/kg和6.05，1.63，4.99，58.44 mg/kg。林地的土壤有机质 ...

Role of funders in embedding tests in conservation practice
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Effective conservation practice requires decisions based on reliable and relevant evidence, but significant gaps in the evidence base exist. Incorporating well‐designed tests of the effectiveness of interventions for biodiversity in conservation projects is one of the best ways to scale up the rate of evidence generation.

Shuitu Baochi Xuebao, 2007 通过对沙坡头地区不同植被类型沙地土壤表层水分时空变化特征的研究表明，该区不同植被类型沙地土壤表层水分的分布均符合正态分布，降雨使表层土壤水分的空间变异性减小，空间自相关性减弱，分维数减小，空间自相关范围由干旱时的5m左右内变化扩大到几十米，土壤表层水分的空间依赖性增强；在土壤表层水分含量极低的情况下，土壤表层水分的空间变异性规律与土壤水分含量的变化规律一致；在土壤水分含量不是很低的情况下，其空间变异性与土壤表层水分含量变化趋势相反，流沙地、柠条地A、柠条地B、油蒿地 ...

Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

, 2014 利用分街道(乡、镇)一级人口普查和调查数据,分析了2011年乌鲁木齐城区人口密度、流动人口、老龄人口、不同学历人口、不同职业、行业人口等主要社会指标的空间分异特征,并运用信息熵、分异指数模型测算1982年、2000年和2011年3个时间截点城市各社会要素的分异变化趋势。研究表明:乌鲁木齐城市社会空间分异主要体现在居民职业既经济状况的差异上,教育水平等其他因素的差异造成的空间分异相对较小。1982-2011年的30 a间,除哈萨克族人口、回族人口、大专及以上学历人口等部分指标外 ...
