Asymptotic behavior of pullback attractors for non-autonomous micropolar fluid flows in 2D unbounded domains

Electronic Journal of Differential Equations, 2018
In this article, we investigate the pullback asymptotic behavior of solutions for a non-autonomous micropolar fluid flows in 2D unbounded channel-like domains. First, applying the technique of truncation functions, decomposition of spatial domain, and

Fractional Flow Reserve Directed Percutaneous Coronary Intervention Optimization Using High‐Definition Intravascular Ultrasound in Non‐ST‐Segment Elevation Acute Coronary Syndrome Versus Chronic Coronary Syndrome

Catheterization and Cardiovascular Interventions, Volume 106, Issue 1, Page 12-22, July 1, 2025.
ABSTRACT Background Intravascular ultrasound (IVUS)‐guided optimization of suboptimal fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) results in a significant increase in both post‐PCI FFR and minimal lumen and stent areas (MLA and MSA, respectively).

Virtual pullbacks in K-theory [PDF]

Annales de l’institut Fourier, 2018
We consider virtual pullbacks in $K$-theory, and show that they are bivariant classes and satisfy certain functoriality. As applications to $K$-theoretic counting invariants, we include proofs of a virtual localization formula for schemes and a degeneration formula in Donaldson-Thomas theory.

Pullback attractors for a class of semilinear nonclassical diffusion equations with delay

Electronic Journal of Differential Equations, 2016
In this article, we analyze the existence of solutions for a nonclassical reaction-diffusion equation with critical nonlinearity, a time-dependent force with exponential growth and delayed force term, where the delay term can be entrained by a ...

Coronary Plaque Characteristics Assessed by Optical Coherence Tomography and Plasma Lipoprotein(a) Levels in Patients With Acute Coronary Syndrome

Catheterization and Cardiovascular Interventions, Volume 106, Issue 1, Page 64-72, July 1, 2025.
ABSTRACT Background Lipoprotein(a) [Lp(a)] is associated with increased cardiovascular risk, but its influence on plaque characteristics at optical coherence tomography (OCT) evaluation is not fully understood. Aims This study seeks to explore the impact of Lp(a) levels on plaque morphology as assessed by OCT in a very high‐risk subset of patients ...

Unraveling Hierarchical Brain Dysfunction in Major Depressive Disorder: A Multimodal Imaging and Transcriptomic Approach

Human Brain Mapping, Volume 46, Issue 10, July 2025.
Dysfunctional hierarchy in major depressive disorder (MDD) features decreased SDI in regions linked to high‐order cognitive functions, like the prefrontal, parietal, and orbitofrontal cortices. Conversely, areas related to low‐level sensory‐motor functions, the somatosensory cortex, showed increased SDI in MDD.

A pullback theorem for cofibrations

Manuscripta Mathematica, 1987
In this note we prove a pullback theorem for cofibrations, which extends a well known theorem of Strom [5]. It also implies the pullback theorem of Heath [4] for locally equiconnected spaces. In addition, we comment on the dual problem of attaching fibrations.

Effects of Adding Transversus Abdominis Plane Block on Intravenous Nalbuphine and Dexmedetomidine for Severely Pre‐Eclamptic Parturients After Cesarean Delivery

The Kaohsiung Journal of Medical Sciences, Volume 41, Issue 7, July 2025.
ABSTRACT The use of opioids is frequently associated with the occurrence of adverse effects during cesarean delivery, especially for primiparous women with severe preeclampsia, creating a critical need for investigation of alternative analgesic strategies.

Polar Coordinates for the 3/2 Stochastic Volatility Model

Mathematical Finance, Volume 35, Issue 3, Page 708-723, July 2025.
ABSTRACT The 3/2 stochastic volatility model is a continuous positive process s with a correlated infinitesimal variance process ν$\nu $. The exact definition is provided in the Introduction immediately below. By inspecting the geometry associated with this model, we discover an explicit smooth map ψ$ \psi $ from (R+)2$({\mathbb{R}}^+)^2 $ to the ...

Moduli of finite flat torsors over nodal curves

Journal of the London Mathematical Society, Volume 112, Issue 1, July 2025.
Abstract We show that log flat torsors over a family X/S$X/S$ of nodal curves under a finite flat commutative group scheme G/S$G/S$ are classified by maps from the Cartier dual of G$G$ to the log Jacobian of X$X$. We deduce that fppf torsors on the smooth fiberss of X/S$X/S$ can be extended to global log flat torsors under some regularity hypotheses.
