aTo accomplish this, we develop a structural model linking a firmís R&D effort with its decision to patent, recognizing that R&D and patenting affect one another and are both driven by many of the same factors. 完成这,我们发展以其决定连接一种 firmis R&D 努力将注册专利,承认的一个结构的模型...
3. How do neighborhood built environment influences on young children’s outdoor free play differ across child gender, cultures, and geographies? Methods Search Strategy We prospectively registered our review protocol (PROSPERO, CRD42020173288) and searched seven research databases: Avery Index, ERIC, ...
Thiophenes Fusion of the thiophene ring with the pyrone ring of coumarin(benzopyrane) leads to three structural isomers, viz. 4H-thieno[2,3-c]chromen(benzopyran)-4-one, 4H-thieno[3,4- c]chromen(benzopyran)-4-one, and 4H-thieno[3,2-c] chromen(benzopyran)-4-on...

However, PZT pumps with a valve might be easily fatigued and damaged, have relatively high structural complexity, and can generally obtain higher flow rate and back pressure than valveless PZT pump. The valveless PZT pumps, however, have simpler structures and are easier to be miniaturized [1,...
Hangouët [10] focuses on grouping of buildings along roads using thiessen polygons and structural data. Regnauld [11,12] uses minimum spanning tree and proximity graphs for typification. He then analyzes their structure in compliance with the criteria of gestalt theory by Wertheimer [13]. ...
