W-JAFFARD DOMAINS IN PULLBACKS [PDF]
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 (

The Existence of Weak D-Pullback Exponential Attractor for Nonautonomous Dynamical System
First, for a process U(t,τ)∣t≥τ, we introduce a new concept, called the weak D-pullback exponential attractor, which is a family of sets M(t)∣t≤T, for any T∈R, satisfying the following: (i) M(t) is compact, (ii) M(t) is positively invariant, that is, U(t,

Criteria for strong and weak random attractors
The theory of random attractors has different notions of attraction, amongst them pullback attraction and weak attraction. We investigate necessary and sufficient conditions for the existence of pullback attractors as well as of weak ...

Coherentlike conditions in pullbacks.
Let \(M\) be a (nonzero) maximal ideal of a domain \(T\), let \(k=T/M\) be the residue field, let \(\varphi: T\to k\) be the natural projection, and let \(D\) be a proper subring of \(k\). Let \(R= \varphi^{-1} (D)\) be the domain arising from the following pullback of canonical homomorphisms: \[ \begin{matrix} R & \to & D \\ \downarrow & & \downarrow \

Pullback incremental attraction
AbstractA pullback incremental attraction, a nonautonomous version of incremental stability, is introduced for nonautonomous systems that may have unbounded limiting solutions.

Compactified universal jacobian and the double ramification cycle
Using the compactified universal jacobian over the moduli space of stable marked curves, we give an expression in terms of natural classes of the zero section of the compactified universal jacobian the (rational) Chow ring.

Herein, a patient‐mounted neuro optical coherence tomography system that integrates a 5 degrees‐of‐freedom skull‐mounted robot (Skullbot) with a 0.6 mm neuroendoscope for targeted, minimally invasive deep brain imaging, is developed. The system offers high‐resolution imaging with precise deployment, demonstrated through successful tumor imaging in a ...

Effect of Pullback Speed and the Distance between the Skin and Vein on the Performance of Endovenous Laser Treatment by Numerical Simulation [PDF]
Introduction: Endovenous laser treatment (ELT) is a new treatment method for the reflux of the great saphenous vein. A successful ELT is dependent on the selection of optimum parameters required to achieve optimal vein damage while avoiding side effects ...

Bench Testing Analysis of Perforation Management in the Setting of Bifurcation Coronary Intervention
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 ...
