Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.

Design and Implementation of Students’ Comprehensive Evaluation System Based on SSH Framework [PDF]
, 2015 随着各高校进一步加强综合素质教育，全面客观评价大学生在校期间的表现显得尤为重要。因此，建立一个方便易用的学生综合评价系统，并提出一种能相对客观准确的进行学生评价的方法以方便奖学金发放等具有十分积极的意义。依据上述相关类教务系统的需求以及数据与服务相分离的原则，采用集成SSH框架的JavaEE技术，构建一种B/S模式的Web应用，能够将需求划分为表现层、业务逻辑层、数据持久层的简明体系结构，方便清晰，可复用、易维护。同时，为了客观评价学生，以广泛收集学生在校期间表现的活动数据为基础 ...

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

Gaoya dianqi, 2013 为了解决在线油色谱受外界环境和设备误差影响导致数据失真的问题,笔者提出了一种基于萤火虫支持向量机的油色谱在线数据校正的方法。首先将支持向量机中的一组错误惩罚因子,不敏感参数和核参数作为萤火虫个体,通过萤火虫算法对影响支持向量机性能的重要参数进行优化。然后计算油色谱离线数据间的分段函数,当在线数据超出分段函数误差允许的范围时,认为在线数据异常。利用少数准确的油色谱离线数据对支持向量机回归模型进行训练,当在线数据出现异常时,通过支持向量机回归模型对异常的在线数据进行校正 ...

Remote sensing of the extent of the Bohai sea ice and temperature anomaly of ocean interior during recent global surface warming hiatus [PDF]
, 2015 自1998年起，全球表面出现增暖减缓，全球气候处在深度调整中。我国近岸对此出现不同程度的响应，极端海洋灾害事件频发。2009-2010年冬季，受北方持续寒潮的影响，渤海出现了历史罕见的严重海冰冰情，海冰成为2010年中国海洋主要灾害之一。通过冰冻区遥感影像分类准确有效地提取海冰分布信息对于检测和评估海冰演化过程是至关重要的。我们提出一种新的基于融合多特征的机器学习影像分类技术，有效地用于MODIS冰冻区影像分类及海冰分布范围估算。通过灰度共生矩阵（GLCM）纹理特征分析提取MODIS影像纹理特征 ...

Integrative Conservation, Volume 4, Issue 4, Page 600-615, December 2025.Only 1541 (34.2%) of 4503 recognized non‐passerine bird species are held in ZIMS institutions worldwide. Approximately ~83% of the species kept globally are classified as non‐threatened and ~16% as threatened. To improve the conservation of threatened birds, a shift toward keeping threatened species should be considered within ex situ management ...
