Thoracoscopic division of vascular rings
Journal of Pediatric Surgery, 2017Vascular rings are traditionally treated via an open thoracotomy. In recent years the use of thoracoscopy has increased. Herein we report our experience with thoracoscopic division of vascular rings in pediatric patients.We reviewed all patients who underwent thoracoscopic or open division of a vascular ring at our institution between 2007 and 2015. We

The following results (9, Exercise 26, p. 10; 1, Theorem 9.2; 8, Theorem III. 1.11) are known.(A) Let R be a ring with more than one element. Then R is a division ring ifand only if for every a ≠0 in R, there exists a unique b in R such that aba = a.(B) Let R be a near-ring which contains a right identity e ≠ 0.

In this chapter we introduce the central object of study in this book: valuations on a division algebra D finite-dimensional over its center F. In §1.1 we define valuations and describe the associated structures familiar from commutative valuation theory: the valuation ring \(\mathcal {O}_{D}\), its unique maximal left and maximal right ideal ...

The study of quantum polynomial rings was initiated by J. C. McConnell and J. J. Pettit [MP] as multiplicative analog of the Weyl algebra. They are of considerable interest in non-commutative algebraic geometry.
