Jugular Vein Catheterization in Critically Ill Patients with Coronavirus Disease 2019 Can Increase the Surgeon’s Exposure

Vascular Specialist International, 2020
Mechanochemical ablation (MOCA) is a non-thermal, non-tumescent technique for the treatment of incompetent saphenous vein. It is sometimes difficult to maintain consistency when simultaneously implementing wire rotation, sclerosant injection, and wire ...

Nontautological cycles on moduli spaces of smooth pointed curves

Bulletin of the London Mathematical Society, EarlyView.
Abstract In recent work by Arena, Canning, Clader, Haburcak, Li, Mok, and Tamborini, it was proven that for infinitely many values of g$g$ and n$n$, there exist nontautological algebraic cohomology classes on the moduli space Mg,n$\mathcal {M}_{g,n}$ of smooth genus g$g$, n$n$‐pointed curves.

W-JAFFARD DOMAINS IN PULLBACKS [PDF]

Journal of Algebra and Its Applications, 2012
In this paper we study the class of w-Jaffard domains in pullback constructions, and give new examples of these domains. In particular we give examples to show that the two classes of w-Jaffard and Jaffard domains are incomparable. As another application, we establish that for each pair of positive integers (n, m) with n + 1 ≤ m ≤ 2n + 1, there is an (

Existence of a random attractor for non-autonomous stochastic plate equations with additive noise and nonlinear damping on R n $\mathbb{R}^{n}$

Boundary Value Problems, 2020
Based on the abstract theory of pullback attractors of non-autonomous non-compact dynamical systems by differential equations with both dependent-time deterministic and stochastic forcing terms, introduced by Wang in (J. Differ. Equ. 253:1544–1583, 2012),

On the finiteness of maps into simple abelian varieties satisfying certain tangency conditions

Bulletin of the London Mathematical Society, EarlyView.
Abstract We show that given a simple abelian variety A$A$ and a normal variety V$V$ defined over a finitely generated field K$K$ of characteristic zero, the set of non‐constant morphisms V→A$V \rightarrow A$ satisfying certain tangency conditions imposed by a Campana orbifold divisor Δ$\Delta$ on A$A$ is finite.

Pullbacks of Prüfer rings

Journal of Algebra, 2008
AbstractIn this paper we consider five extensions of the Prüfer domain notion to commutative rings with zero-divisors and investigate their behavior in a special type of pullback called a conductor square. That is, for a pair of rings R⊂T with non-zero conductor of T into R, we find necessary and sufficient conditions on the rings T, T/C, and R/C in ...

Stability of random attractors for non-autonomous stochastic $ p $-Laplacian lattice equations with random viscosity

AIMS Mathematics
In this paper, we investigate the stability of pullback random attractors for non-autonomous stochastic $ p $-Laplacian lattice systems, which are influenced by random viscosity and multiplicative white noise. Under appropriate conditions, we first prove

On the Dimension of the Pullback Attractors for g-Navier-Stokes Equations

Discrete Dynamics in Nature and Society, 2010
We consider the asymptotic behaviour of nonautonomous 2D g-Navier-Stokes equations in bounded domain Ω. Assuming that f∈Lloc2, which is translation bounded, the existence of the pullback attractor is proved in L2(Ω) and H1(Ω).

Exponential actions defined by vector configurations, Gale duality, and moment‐angle manifolds

Bulletin of the London Mathematical Society, EarlyView.
Abstract Exponential actions defined by vector configurations provide a universal framework for several constructions of holomorphic dynamics, non‐Kähler complex geometry, toric geometry and topology. These include leaf spaces of holomorphic foliations, intersections of real and Hermitian quadrics, the quotient construction of simplicial toric ...

Motivic p$p$‐adic tame cohomology

Bulletin of the London Mathematical Society, EarlyView.
Abstract We construct a comparison functor between (A1$\mathbf {A}^1$‐local) tame motives and (□¯${\overline{\square }}$‐local) log‐étale motives over a field k$k$ of positive characteristic. This generalizes Binda–Park–Østvær's comparison for the Nisnevich topology.
