Bench Testing Analysis of Perforation Management in the Setting of Bifurcation Coronary Intervention
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Management of coronary perforation in bifurcation lesions with covered stents remains challenging. Aims We aimed to describe a proper practice and toolbox for “jailed‐branch” management after covered stent deployment. Methods Using a bench model, we tested various wires with a 120° angulated microcatheter for their ability to ...

Transfer of the GPIT Property in Pullbacks [PDF]
International Journal of Mathematics and Mathematical Sciences, 2012 Summary: Let \(T\) be a commutative ring, \(I\) a prime ideal of \(T, D\) a subring of \(T/I\), and \(R\) the pullback \(T\times_{T/I}D\). Ascent and descent results are given for the transfer of the \(n\)-PIT and GPIT (generalized principal ideal theorem) properties between \(T\) and \(R\). As a consequence, it follows that if \(I\) is a maximal ideal

Pullback of parabolic bundles and covers of ${\mathbb P}^1\setminus\{0,1,\infty\}$
, 2010 We work over an algebraically closed ground field of characteristic zero. A $G$-cover of ${\mathbb P}^1$ ramified at three points allows one to assign to each finite dimensional representation $V$ of $G$ a vector bundle $\oplus \mathscr{O}(s_i)$ on ...

, 2009 Let f: P^1 \to P^1 be a rational map with finite postcritical set P_f. Thurston showed that f induces a holomorphic map _f of the Teichmueller space T modelled on P_f to itself fixing the basepoint corresponding to the identity map (P^1, P_f) \to (P^1, P_f).

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Introduction Moderate‐to‐severe calcification is present in ~20%–30% of patients undergoing coronary angiography. Coronary lesion modification is often necessary to facilitate optimal stent delivery and expansion, with several dedicated devices now approved for calcium modification before stent implantation. The CYCLOPES study aims to evaluate

Equivariant toric geometry and Euler–Maclaurin formulae
Communications on Pure and Applied Mathematics, EarlyView.Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.

Pullback attractors for the non-autonomous complex Ginzburg–Landau type equation with p-Laplacian
Nonlinear Analysis, 2015 In this paper, we are concerned with the long-time behavior of the non-autonomous complex Ginzburg–Landau type equation with p-Laplacian. We first prove the existence of pullback absorbing sets in L2(Ω)∩W01,p(Ω)∩Lq(Ω) for the process {U(t,τ)}t⩾τ ...

Statistical solution and piecewise Liouville theorem for the impulsive discrete Zakharov equations
AIMS Mathematics, 2022 This article studies the discrete Zakharov equations with impulsive effect. The authors first prove that the problem is global well-posed and that the process formed by the solution operators possesses a pullback attractor. Then they establish that there

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons
Communications on Pure and Applied Mathematics, EarlyView.Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\
