Mangroves provide many ecosystem services including a considerable capacity to sequester and store large amounts of carbon, both in the sediment and in the above-ground biomass. Assessment of mangrove...
In flood-prone areas, the delineation of the spatial pattern of historical flood extents, damage assessment, and flood durations allow planners to anticipate potential threats from floods and to formu...
The mechanical properties of plantation Eucalyptus Nitens timber are currently assessed by applying visual stress grading (VSG) designed for the sawn timber from the mature plantation and do not repre...
Chromatic homotopy theory uses the algebraic geometry of smooth 1-parameter formal groups to separate stable homotopy theory into periodic layers. The 1st layer recovers the image of Adams’ J homomorp...

It is the second-most-disaster-prone region in the world. Latin America and the Caribbean is vulnerable to natural events like earthquakes, floods and hurricanes owing to its unique tectonic structure...
毫米波具有丰富的频率资源,已逐步应用于高速通信和高精度雷达等领域。但由于硅基工艺本身的限制,采用硅基工艺实现毫米波芯片面临巨大的技术挑战。本报告讨论了硅基毫米波芯片技术的发展以及所面临的技术挑战,介绍了本课题组在解决宽带收发链路、高精度毫米波信号源和相控阵等方面的工作,并简要介绍了本课题组开发的毫米波雷达与通信芯片。
经过近70年不间断的防控,我国提出于2030年消除血吸虫病的宏伟目标,并写进《“健康中国2030”规划纲要》。诊断工具在与血吸虫病的斗争中发挥非常重要的角色,但诊断工具应适应各防治阶段血吸虫病的流行情况和防治目标。现阶段我国血吸虫病流行水平及居民和家畜感染强度不断降低,需要具有高敏感性和高特异性的诊断工具去发现病例和满足敏感有效监测体系的需要。分子诊断技术包括变温扩增和等温扩增有可能克服传统病原学...
Research done at Cornell has uncovered from gravitation wave data the first potential signs of spin-orbit resonances in binary black holes, a step toward understanding the mechanisms of supernovas and...
The tiger rattlesnake possesses the simplest, yet most toxic, venom of any rattlesnake species. Now new research led by a University of South Florida biologist explains the genetics behind t...
Forest loss and degradation in the Brazilian Amazon due to mining activities has been intense for many years. To reverse this situation, a range of restoration programs for deforested and degraded are...
据2020年4月Essential Science Indicators(ESI)最新数据显示,Nuclear Science and Techniques(简称NST) 2017年第8期发表的“Search for the QCD critical point with fluctuations of conservedquantities in relativistic heavy-ion c...
The utilization of nanocellulose has increasingly gained attentions from various research fields, especially the field of polymer nanocomposites owing to the growing environmental hazardous of petrole...
As a part of the renewable energy cycle, forest biomass resources are considered to be important renewable materials and energy sources in many countries. It is evident from international and local re...
