Based on the newly constructed input-output model that distinguishes firm size categories and the structural decomposition analysis method, this study quantitatively calculates the employment effects ...
The versatility of the nervous system comes from not only the diversity of ways in which neurons communicate in circuits, but also their “plasticity,” or ability to change those connections when new i...
Identifying and understanding functional process domains (sensu Montgomery, 1999) in rivers is paramount for linking the physical habitat template to ecosystem structure and function.
近日,中国地质大学资源学院马奔奔副教授团队在国际顶级石油地质期刊《AAPG Bulletin》上刊发研究成果,研究成果主要揭示了深埋藏条件下致密砂岩储层水-岩相互作用过程、潜在成岩物质迁移方式及其成岩响应机制。
近日,资源学院博士生王雨轩在国际著名地质学期刊《GSA Bulletin》上刊发研究成果,研究成果主要揭示了重庆涪陵地区五峰-龙马溪组富有机质页岩的多尺度非均质性特征,探讨了富有机质页岩非均质的成因及其对页岩纳米孔隙体系的影响。
近日,中国地质大学生物地质与环境地质国家重点实验室李超教授团队在国际著名地球化学期刊《Geochimica et Cosmochimica Acta》(Nature Index)上发表题为“Spatiotemporal redox heterogeneity and transient marine shelf oxygenation in the Mesoproterozoic ocean”(中...
People learn language from their social environment. As individuals differ in their social networks, they might be exposed to input with different lexical distributions, and these might influence thei...
The problem of urban mobility is complicated by traffic delay, resulting from poor planning, high population density and poor condition of roads within urban spaces. This study assessed traffic conges...
Geochemical studies of shergottites (Martian basalts) based on Rb-Sr, Sm-Nd, and Lu-Hf isotopic systematics have provided clues to understanding the geochemical evolution of the Martian mantle and id...
Extensive structural studies of enzymes have revealed that biological catalysis occurs within sequestered active site crevices, where reacting substrates are surrounded by an anisotropic and chemicall...
The evolution of proteins with novel function is thought to start from precursor proteins that are conformationally heterogeneous. The corresponding genes may be duplicated and then mutated to select ...
Research on income risk typically treats its proxy—income volatility, the expected magnitude of income changes—as if it were unchanged for an individual over time, the same for everyone at a point in ...
Multi-scale segmentation is an essential step toward higher level image processing in remote sensing. This paper presents a new multi-scale segmentation method based on Statistical Region Merging (SRM...
This paper analyzes autoregressive time series models where the errors are assumed to be martingale difference sequences that satisfy an additional symmetry condition on their fourth order mom...
We estimate local multipliers from the ARRA (Obama stimulus) bill using cross-county variation in expenditure. We use within-state variation, and include other demographic controls as well as a pred...
