Flow field through a gate valve installed in a circular pipe and loss coefficient

open access: yesNihon Kikai Gakkai ronbunshu, 2015
The loss coefficient and the flow fields downstream of the typical models of gate valves are investigated experimentally from the surface pressure and velocity distributions measured in the air-pipe flow at Reynolds number 4×104 and the various ...

Magneto‐Electrocatalysis: A Multiscale Perspective on Designing High‐Efficiency Electrocatalysts for Clean Energy

open access: yesBattery Energy, Volume 5, Issue 4, July 2026.
This review presents a multiscale framework for magnetic field‐assisted electrocatalyst synthesis. By synergizing quantum‐scale spin polarization, atomic‐scale force dynamics, and mesoscopic directed assembly, this strategy overcomes conventional design bottlenecks to construct highly efficient, magnetically responsive electrocatalysts for clean energy.

Tessellation Groups, Harmonic Analysis on Non‐Compact Symmetric Spaces and the Heat Kernel in View of Cartan Convolutional Neural networks

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
ABSTRACT In this paper, we continue the development of the Cartan neural networks programme, launched with three previous publications, by focusing on some mathematical foundational aspects that we deem necessary for our next steps forward. The mathematical and conceptual results are diverse and span various mathematical fields, but the inspiring ...

Quantum interference among vortex bound states in superconductors

open access: yesNew Journal of Physics
In a recent experiment (Hou et al 2025 Phys. Rev. X 15 011027), a new type of necklace-like vortex bound state (VBS) was observed and attributed to disorder induced interference among different Caroli–de Gennes–Matricon (CdGM) states within one single ...

From 0D to 3D: Structural Design of Metal‐Organic Framework‐Derived Composites for Next‐Generation Microwave Absorption

open access: yesSmall Structures, Volume 7, Issue 4, April 2026.
This review establishes a dimensional engineering paradigm for MOF‐derived absorbers, transitioning from discrete 0D units to 3D composite architectures. It highlights dimension–structure–performance correlations and provides insights into data‐driven and sustainable design for future high‐efficiency microwave absorption, aiming to guide the ...

Necklacelike Pattern of Vortex Bound States

open access: yesPhysical Review X
A vortex is a topological defect in the superconducting condensate when a magnetic field is applied to a type-II superconductor, as elucidated by the Ginzburg-Landau theory. Because of the confinement of the quasiparticles by a vortex, it exhibits a circular-shaped pattern of bound states with discrete energy levels, as predicted by the Caroli–de ...

Graph potentials and topological quantum field theories

open access: yesProceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.
Abstract We introduce a new functional equation in birational geometry, whose solutions can be used to construct two‐dimensional topological quantum field theories (2d TQFTs), infinite‐dimensional in many interesting examples. The solutions of the equation give rise to a hierarchy of graph potentials, which, in the simplest setup, are Laurent ...

Using Convolutional Neural Networks for the Classification of Suboptimal Chest Radiographs

open access: yesJournal of Medical Radiation Sciences, Volume 73, Issue 1, Page 60-68, March 2026.
This study evaluated DenseNet121 and YOLOv8 neural networks in detecting suboptimal chest x‐rays for quality control. Through training, validation, and testing, both AI models effectively classified chest X‐ray quality, highlighting the potential to provide radiographers with feedback to enhance image quality.

Changes in Spatial Distribution and Abundance Together Determine Potential for Population Persistence for Greater Sage‐Grouse

open access: yesDiversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim Population ecologists often focus on changes in the distribution and abundance of wildlife species, which are useful for trend analyses and status assessments. However, rarely are these responses evaluated simultaneously for a single species, despite their unique contributions to fully assess a species' viability.
