Aiming at the problems of lack of potential implicit relation mining between entities and insufficient head entity information extraction in existing methods, a head entity-enhanced multi-hop attention implicit relations joint mining model Multi-Air (multi-hop attention implicit relations joint mining method) was proposed.The method first uses the
Development and testing of vertical take-off and landing aerial vehicle with tandem electric ducted fan motor
Due to the complexity of control mechanisms, vertical take-off and landing (VTOL) aerial vehicles have not found their way into widespread commercial use.Thanks to the availability of advanced technology, it is possible to develop simpler systems.Such systems could be used in transportation, the military, surveillance, etc.The research work is aime
Ubiquitous dissolved inorganic carbon assimilation by marine bacteria in the Pacific Northwest coastal ocean as determined by stable isotope probing.
In order to identify bacteria that Queen Poster Bed assimilate dissolved inorganic carbon (DIC) in the northeast Pacific Ocean, stable isotope probing (SIP) experiments were conducted on water collected from 3 different sites off the Oregon and Washington coasts in May 2010, and one site off the Oregon Coast in September 2008 and March 2009.Samples
