Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Existence and non-degeneracy of the normalized spike solutions to the fractional Schrödinger equations

Advances in Nonlinear Analysis
The present study investigates the existence and non-degeneracy of normalized solutions for the following fractional Schrödinger equation: (−Δ)su+V(x)u=aup+μu,x∈RN,u∈Hs(RN){\left(-\Delta )}^{s}u+V\left(x)u=a{u}^{p}+\mu u,\hspace{1.0em}x\in {{\mathbb{R}}}^

Fourier Mass Lower Bounds for Batchelor‐Regime Passive Scalars

Communications on Pure and Applied Mathematics, Volume 79, Issue 6, Page 1449-1466, June 2026.
ABSTRACT Batchelor predicted that a passive scalar ψν$\psi ^\nu$ with diffusivity ν$\nu$, advected by a smooth fluid velocity, should typically have Fourier mass distributed as |ψ̂ν|2(k)≈|k|−d$|\widehat{\psi }^\nu |^2(k) \approx |k|^{-d}$ for |k|≪ν−1/2$|k| \ll \nu ^{-1/2}$.

Viscoelastic and Morphologic Changes in the Lumbar Intervertebral Discs of the 5xFAD Mouse Model of Alzheimer's Disease

JOR SPINE, Volume 9, Issue 2, June 2026.
The intervertebral discs (IVDs) from mice with amyloid pathologies are larger, flatter, and exhibit increased energy absorption, making these IVDs more susceptible to damage. This heightened vulnerability may predispose elderly individuals with AD to disc injuries, accelerating IVD degeneration and spinal pain. ABSTRACT Background Chronic low back pain,

The Phoenix Project: Master Constraint Programme for Loop Quantum Gravity

, 2003
The Hamiltonian constraint remains the major unsolved problem in Loop Quantum Gravity (LQG). Seven years ago a mathematically consistent candidate Hamiltonian constraint has been proposed but there are still several unsettled questions which concern the ...

Power and clinical utility of mesopic microperimetry analysis strategies in age‐related macular degeneration

Acta Ophthalmologica, Volume 104, Issue 3, Page e292-e299, May 2026.
Abstract Purpose This study evaluates whether mesopic microperimetry (MMP) provides a more robust measure of retinal function compared to visual acuity (VA) in age‐related macular degeneration (AMD) clinical trials, with a focus on optimal analysis strategies. Method Fellow‐eyes of unilateral neovascular AMD were prospectively studied.

Identification and Estimation of Large Network Games with Private Link Information

International Economic Review, Volume 67, Issue 2, Page 411-432, May 2026.
ABSTRACT We study the identification and estimation of large network games in which individuals choose continuous actions while holding private information about their links and payoffs. Extending the framework of Galeotti et al., we build a tractable empirical model of such network games and show that the parameters in individual payoffs are ...

Closure and commutability results for Gamma-limits and the geometric linearization and homogenization of multi-well energy functionals

, 2013
Under a suitable notion of equivalence of integral densities we prove a $\Gamma$-closure theorem for integral functionals: The limit of a sequence of $\Gamma$-convergent families of such functionals is again a $\Gamma$-convergent family.

Multimodal Cross‐Attentive Graph‐Based Framework for Predicting In Vivo Endocrine Disruptors

Advanced Science, Volume 13, Issue 21, 13 April 2026.
A multimodal cross‐attentive graph neural network integrates molecular graphs with androgen and estrogen adverse outcome pathway (AOP)–anchored in vitro assay signals to predict in vivo endocrine disruption. By fusing information on Tier‐1 AOP logits with chemical structures, the framework achieves high accuracy and provides assay‐traceable ...

Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs

Communications on Pure and Applied Mathematics, Volume 79, Issue 4, Page 1012-1072, April 2026.
Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure
