Kongjian kexue xuebao, 2023 精确的恒星星等信息是开展导航星表建立、航天器定姿、红外相机定标等工作的基础，现有公开星表涵盖测光波段不全且带宽普遍较窄，难以找到与任务传感器响应波段相匹配的星等信息。为此提出了一种基于恒星辐射光谱的传感器响应波段星等计算方法。该方法利用公开星表数据信息，建立星表测光波段与传感器响应波段星等差值模型，对星表星等与传感器响应波段星等差值进行估算；将色指数计算的恒星近似表面温度作为先验信息，在传感器响应波段区间进行普朗克方程求解，进而推算恒星在传感器响应波段的星等。星表数据计算验证表明 ...

Methodology to identify ecologically matching areas and its applications in conservation planning
Conservation Biology, EarlyView.Abstract Identifying ecologically matching areas is both challenging and critical for understanding spatial patterns of biodiversity and advancing conservation planning. However, existing approaches often lack spatial flexibility, overlook shape and size constraints, or rely on limited environmental parameters, reducing their effectiveness in real ...

野生动物学报, 2022 通过查验2018年11月以来在山西蟒河猕猴国家级自然保护区38个相机位点红外相机所拍摄的影像资料，发现该保护区有4个位点共4次记录了黄腹鼬（Mustela kathiah）的影像。经比较核查，确证黄腹鼬为山西省的新纪录物种，其分布北界扩展到了山西南太行山区域，刷新了该物种分布的最北界。

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 9, September 2026.ABSTRACT Ultrathin sodium (Na) metal anodes (< 40 μm) with superior electrochemical performance are essential in developing high‐energy‐density sodium metal batteries (SMBs). Nonetheless, Metallic Na's poor processability hinders its practical application.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Platinum‐based electrocatalysts are fundamentally constrained by strong oxygen binding, which restricts the oxygen reduction reaction (ORR) kinetics, and by severe CO poisoning, which hinders the methanol oxidation reaction (MOR). To address these limitations, we synthesized PdPtRuIrRhNi high‐entropy alloy (HEA) mesoporous nanotubes that ...

Wildlife Letters, Volume 4, Issue 3, Page 131-138, September 2026.Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...

Shuitu Baochi Xuebao, 2001 应用磁测方法并结合土壤理化指标 ,对相同母质发育但利用方式和熟化程度不同的浙西红壤磁性特征进行研究。结果表明 ,6种利用方式的红壤中 ,耕植年限长、熟化程度高的红壤由于土壤结构、p H值和有机质含量的改善 ,磁性特征有明显变化 ,磁性矿物由亚铁磁性矿物向不完整反铁磁性矿物方向发展 ,且超顺磁性矿物和单畴磁性矿物含量减少。此外 ,耕植年限相同的红壤磁性相近 ,裸地红壤的磁性低值反映了裸地表土强烈侵蚀状况。

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.
