The impact of pullback measurement on treatment decision in significant coronary artery disease: Insights from a retrospective multicentric study [PDF]
Background: Optimal management of coronary artery disease (CAD) requires tailoring treatment strategies to lesion characteristics. Intracoronary pullback enables hemodynamic mapping of coronary lesions, potentially improving therapeutic decision-making ...

Entropy Increase in Switching Systems [PDF]
The relation between the complexity of a time-switched dynamics and the complexity of its control sequence depends critically on the concept of a non-autonomous pullback attractor.

Classification of 1-absorbing comultiplication modules over a pullback ring [PDF]
One of the aims of the modern representation theory is to solve classification problems for subcategories of modules over a unitary ring R. In this paper, we introduce the concept of 1-absorbing comultiplication modules and classify 1-absorbing ...

Flatness properties of acts over semigroups [PDF]
In this paper we study flatness properties (pullback flatness, limit flatness, finite limit flatness) of acts over semigroups. These are defined by requiring preservation of certain limits from the functor of tensor multiplication by a given act. We give

Pullback Attractors for a Nonautonomous Retarded Degenerate Parabolic Equation
This paper is devoted to a nonautonomous retarded degenerate parabolic equation. We first show the existence and uniqueness of a weak solution for the equation by using the standard Galerkin method.

Pullback dan Pushout di Kategori Modul Topologis
A pullback of two morphisms with a common codomain $f\colon A\to C$ and $g\colon B\to C$ is the limit of a diagram consisting $f$ and $g$. The dual notion of a pullback is called a pushout. A pushout of two morphisms with a common domain $k\colon A\to B$

Degenerate pullback attractors for the 3D Navier-Stokes equations [PDF]
As in our previous paper, the 3D Navier-Stokes equations with a translationally bounded force contain pullback attractors in a weak sense. Moreover, those attractors consist of complete bounded trajectories.
