Conservation Biology, EarlyView.Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Synthesizing Empirical Research on Learner Metacognition in Second Language Writing
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite considerable research interest in learner metacognition in second language (L2) writing, there is not yet a review that synthesizes the existing empirical findings and discusses their implications. To fill the void, this systematic review synthesized 39 empirical studies on learner metacognition in L2 writing and examined their salient

, 2011 准确对事件诱发电位(ERPs)进行分类，对于各种人类认知研究和临床医学评估非常有意义．由于ERPs 信号是非常高维的数据，而且其中包含非常多的与分类无关的信息，从ERPs 信号中提取特征尤显重要．分析了共空间模式(CSP)的原理和不足，引入自回归(AR)模型与白化变换相结合，提出了针对ERPs 分类的时空特征提取方法，并设计了验证该方法的认知实 验，在认知实验数据上分别用时空特征提取方法与CSP 提取特征，用同样的分类器支持向量机(SVM)训练分类器，比较它们的分类效果．实验表明，在ERPs分类问题上，

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Lightweight and lead‐free radiation shielding materials remain urgently needed. This work designed a fluorite high‐entropy oxide (FHEO) system through a combined computational–experimental route. Density functional theory based on special quasi‐random structures was used to identify thermodynamically stable fluorites from a wide compositional ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Multimodal luminescent materials are crucial for advanced information encryption, real‐time dosimetry, and high‐resolution bioimaging, yet integrating orthogonal stimulus‐responsiveness into a single‐component system is challenging. Herein, we report a Pr3+‐doped Ca3Ga2Ge3O12 (CGGO: Pr3+) garnet phosphor that exhibits orthogonally addressable ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

A hybridized method for remote sensing digital images matching(一种遥感数字图像匹配的合成算法)
Zhejiang Daxue xuebao. Lixue ban, 2005 分析了传统的基于灰度和基于特征的匹配算法，提出了一种基于边缘特征和相关系数的新匹配算法.该算法首先对潜在匹配图像和模板图像利用高斯拉普拉斯(LOG)算子和梯度算子提取影像的边缘，然后提取二值化图像，最后再利用相关系数法对二值化后的边缘影像进行匹配运算，得到正确的匹配结果.该算法融合了传统算法的优点.利用该算法对上海的SPOT5 m分辨率不同波段的卫星影像进行了匹配试验，获取了比较好的匹配效果.
