智能科学与技术学报, 2019 发电侧控制是整个电网稳定运行的基础，而现有的控制方法已不能满足能源、环境以及人类社会等对发电侧日益增长的需求。为保证发电过程的安全性、高效性和环境友好性，提出了基于 ACP 方法的平行发电控制系统理论。首先，构建与实际物理发电控制系统等价的人工发电控制系统；接下来通过人工发电控制系统的计算实验，选择最优被控对象模型及其对应的控制策略来对物理控制系统的运行进行引导，并对其行为进行评估，使其逐渐趋近人工控制系统；然后，通过发电过程中物理控制系统和人工控制系统的平行执行，确保发电侧的运行稳定性 ...

大数据跨域算力网络希望整合多个算力中心的计算和数据资源，但现有的方案对跨域文件和数据管理关注不够。提出了一种轻量级的跨域算力网络数据管理方案：通过文件系统协议转换，接入远程算力中心的并行文件系统存储资源；算力中心内部的存储资源作为一种补充，应对高IOPS应用；通过容器绑定技术，将远程存储挂载并绑定到指定目录。基于该方案的原型系统已经在高校校级计算平台部署运行。实测数据和用户体验显示，该方案能够满足常见高性能计算应用需求。

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
Policy Studies Journal, EarlyView.ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.

Jianzhu Gangjiegou Jinzhan, 2021 中空夹层圆钢管混凝土短柱在轴压作用下,混凝土材料受到内外钢管约束处于三向受压状态,其抗压承载力较普通混凝土有较大提升。提升幅度与侧压应力有直接关系,侧压应力大小取决于截面尺寸及其所受轴力。现行设计方法认为同一构件在轴压和纯弯状态下侧压应力大小相同,对于偏压状态下的侧压应力如何考虑未明确说明。对此,引入与轴力相关的侧压应力系数β修正混凝土的本构关系,明确在各种受力状态下如何考虑侧压应力的影响。还提出一种应力积分算法用于计算短柱构件的极限承载力,得到短柱截面的轴力-弯矩(N-M)曲线。最后 ...

Equine Veterinary Journal, Volume 58, Issue 6, Page 1627-1635, November 2026.Abstract Background The middle conchal sinus (MCS) (ethmoidal sinus) remains one of the least understood equine paranasal compartments. Despite recognition of its involvement in sinonasal disease, disorders of the MCS often remain underdiagnosed in the absence of computed tomographic (CT) imaging due to limited anatomical understanding and challenges ...

Shiyou jixie, 2014 目前注水管柱在井筒液体中所受浮力主要采用浮重法计算，与现场实际情况不符。为此，开展了管柱单元结构浮力研究，引进了修正因子——侧浮力，用以对现有单元浮力计算公式进行修正。通过等效原理建立注水管柱单元结构浮力的力学计算公式，并在定向井上对注水管柱浮力进行计算，通过理论验证，证明了改进后的单元结构浮力计算公式的正确性。建议管柱力学分析采用修正后的单元结构浮力计算公式，以提高分析计算结果的准确性。

World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT Household food expenditure continues to be a key factor in ensuring the realization of the Human Right to Adequate Food. Particularly in Brazil, access to food can be limited by economic constraints in vulnerable families, especially among farming families, who have been more vulnerable to food insecurity in recent years in the country.

Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT Public consultations are a cornerstone of democratic policymaking, yet the sheer volume and heterogeneity of submissions often overwhelm traditional analysis. Emerging large language models (LLMs) offer new opportunities for making sense of such data, but their performance in contexts with high linguistic and technical diversity remains ...

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 ...
