Partial differential equations (PDEs) have become an essential tool for modeling complex physical systems. Such equations are typically solved numerically via mesh-based methods, such as the finite el...
北京时间2022年9月5日12点52分 (UTC 2022-9-5 04:52:20) 在我国四川省泸定县发生了M6.8级地震。地震发生后,我们从IRIS数据中心下载了地震数据资料用于研究地震震源机制和震源破裂过程。选取其中信噪比较高并且沿方位角分布比较均匀的19个远场P波波形(震中距位于30°<△<90°范围之内)和21个SH波波形资料进行点源模型的震源机制解反演;根据反演结果构建有限断层模型进...
Reproduction is a complex process, requiring a huge variety of molecular and cellular interactions, many aspects of which remain a mystery to science.
The fast-moving decline and extinction of many species of detritivores -- organisms that break down and remove dead plant and animal matter -- may have dire consequences, an international team of scie...
Identifying and understanding functional process domains (sensu Montgomery, 1999) in rivers is paramount for linking the physical habitat template to ecosystem structure and function.
Subfossil chironomids are regarded as a useful biological proxy for palaeoenvironmental research, but picking chironomid head capsules from aquatic sediments is extremely time-consuming.
Microbes in sediment below the seafloor are sustained primarily by chemicals created by the natural irradiation of water molecules, report U.S. National Science Foundation-funded researchers at t...
The pan-sharpening is a widely used operation in remote sensing image processing, this operation aims at combining an observable high spatial resolution panchromatic image with a multispectral one, to...
Technological improvements made in recent years of mass data gathering and analyzing, influenced the traditional methods of updating and forming of the national topographic database. It has brought a ...
2018年1月,有关“南美洲新近系Orinoco三角洲大陆架及陆架边缘沉积演化”的研究成果刊发在美国地质学会国际重要期刊《Geological Society of America Bulletin》上。该文第一作者为中国地质大学资源学院副教授陈思博士。
In the process of geothermal exploitation and utilization, the reinjection amount of used geothermal water in super-deep and porous reservoir is small and significantly decreases over time. This has b...
An artificial system using a DNA-laced hydrogel can receive a chemical signal and release the appropriate protein, according to Penn State researchers. Further stimulation by the chemical signal conti...
The aim of the present research is to develop an instrument able to adequately support the conservation process by means of a twofold approach, based on both BIM environment and ontology formalisation...
