This paper quantitatively investigates the effect of transportation system on trade flows of four major port cities in China. Due to the significant country-pair heterogeneities in both intercept and ...
In this talk, the combined quasi-neutral and zero-viscosity limits of the two-fluid Navier-Stokes-Poisson systems (one for ion and another for electron) with boundary are rigorously proved by investig...
In this work, we propose and analyze domain decomposition methods to decouple the large system arisen from the discretization of dual-porosity-Stokes model. Robin boundary conditions are used to decou...
Computer chips are packed with billions of microscopic transistors that enable powerful computation, but also generate a great deal of heat. A buildup of heat can slow a computer processor and make it...
Scientists using NASA’s James Webb Space Telescope have captured definitive evidence of carbon dioxide in the atmosphere of a planet beyond our solar system.
The following press release was issued today by the Broad Institute of MIT and Harvard.
MIT chemists have devised a new chemical reaction that allows them to synthesize a phosphorus-containing ring, using a catalyst to add phosphorus to simple organic compounds called alkenes.
Ateam of researchers led by Harvard and Broad Institute scientists has developed a new drug-delivery system using engineered DNA-free virus-like particles (eVLPs) that is able to edit genes associated...
Twin gene-editing system gives twice the efficiency(图)     基因编辑  双胞胎  DNA片段  可编程操作       font style='font-size:12px;'> 2023/6/21
Ateam of researchers led by Harvard and Broad Institute scientists has developed twin prime editing, a new, CRISPR-based gene-editing strategy that enables manipulation of gene-sized chunks of DNA in ...
When Sharif Tabebordbar was a teenager, his father began having trouble walking. Soon, he became wheelchair-bound and was diagnosed with a rare genetic muscle disease.
近日,国家地理信息系统工程技术研究中心陈能成教授团队在地球科学领域顶级期刊《Earth-Science Reviews》(IF=12.413)上刊发研究成果—Spatiotemporal forecasting in earth system science: Methods, uncertainties, predictability and future directions。该文针对地球系统...
Smart laser cutter system detects different materials(图)     智能  激光切割机  智能材料  传感平台  SensiCut       font style='font-size:12px;'> 2023/6/7
With the addition of computers, laser cutters have rapidly become a relatively simple and powerful tool, with software controlling shiny machinery that can chop metals, woods, papers, and plastics. Wh...
System trains drones to fly around obstacles at high speeds     arithmetic  drone  aerodynamics       font style='font-size:12px;'> 2021/8/11
A new algorithm helps drones find the fastest route around obstacles without crashing. The system could enable fast, nimble drones for time-critical operations such as search and rescue.
A major Atlantic ocean current -- the Atlantic Meridional Overturning Circulation, or AMOC -- may have been losing stability in the course of the last century, according to new research. A potential c...
Freshwaters are important emitters of carbon dioxide (CO2) and methane (CH4), two potent greenhouse gases (GHGs).
