Abstract: Phthalhydrazide is proved to be an elegant N=N source to undergo tandem dual-C−N coupling/deprotection/oxidation with not only cyclic/linear diaryliodoniums but also rarely explored diarylbromoniums, giving benzo[c]cinnolines (up to 99% yield)... read more here.

Abstract: BACKGROUND Volumetric lung tumor segmentation is difficult due to the diversity of the sizes, locations and shapes of lung tumors, as well as the similarity in the intensity with surrounding tissue structures. OBJECTIVE We propose… read more here.
