Abstract: Three polymorphs of the title compound were found, showing a head‐to‐tail (N–O)2 four‐membered ring. The aand b phases underwent a reversible structural phase transition across ca. 140 K, while the g phase was independent. The interatomic O…N distances are 79‐81% of the… read more here.

Abstract: A bstractWe construct four-center bubbled BPS solutions with a Gibbons-Hawking base space. We give a systematic procedure to build scaling solutions: starting from three-supertube configurations and using generalized spectral flows and gauge transformations to extend… read more here.

Abstract: Background Neuroblastoma, mainly affecting children, is a lethal malignancy arising from the developing sympathetic nervous system. The genetic etiology of neuroblastoma remains mostly obscure. High mobility group AT-hook 2 (HMGA2), an oncogenic gene, is up-regulated… read more here.
