平行智能风沙防护治理决策支持系统——塔克拉玛干沙漠公路及其防沙体系
针对风沙防护治理系统难以建模、难以解析预测等问题,以塔克拉玛干沙漠公路及其防沙体系为研究对象,提出平行智能风沙防护治理决策支持系统。基于防沙专家常年积累的经验知识,结合实际系统风沙环境信息,模拟风沙防护治理过程,构建沙漠公路防沙体系人工系统;基于计算实验,评估防沙体系人工系统的防沙效果,通过与实际系统进行比较与学习,对系统进行评估与校准;基于平行智能理论,分析风沙防护治理决策支持系统,实现人工系统与实际系统的相互学习、相互借鉴,为风沙防护治理提供决策支持,促进风沙环境可持续化发展。

ABSTRACT Multifunctional thermal protective ceramic thermal/environmental barrier coatings (T/EBCs) are of great significance for applications of various high‐temperature components, and we propose an effective strategy for designing high‐entropy ceramics (HECs) as T/EBCs for SiC ceramic matrix composites (CMCs), where low thermal expansion ...

Scientists’ warning on the global destruction of rock outcrop ecosystems
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

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 ...

Canine Distemper Virus Research in China and Future Directions for Conservation 中国犬瘟热病毒研究现状与保护策略展望
ABSTRACT Canine distemper is a highly contagious, severe disease caused by the canine distemper virus (CDV). With a worldwide distribution and ever‐expanding list of susceptible hosts, CDV poses a growing risk for many threatened wildlife species, both in captivity and their native habitats. As a megadiverse country, China is home to myriad endemic and

ABSTRACT Aqueous zinc batteries hold great promise for large‐scale energy storage, yet their practical application is hindered by dendrite growth and interfacial side reactions on the zinc anode. Inspired by the industrially mature chromate passivation technology, this work reports an in situ construction of a chromium‐rich passivation layer (Zn@Cr) on
