Association of Transition Zone Burden With Recurrence in Elderly Patients With Paroxysmal Atrial Fibrillation Without Low‐Voltage Areas

open access: yesClinical Cardiology, Volume 49, Issue 9, September 2026.
Transition zone (TZ) is defined as regions with bipolar voltage between 0.5 and 1 mV in left atrium. In 158 elderly PAF patients without low‐voltage areas (LVA), TZ burden is associated with reduced left atrial conduction velocity (LACV) and independently predicts atrial tachyarrhythmia (ATA) recurrence following CPVI.

Conformal and Multi‐Domain Radio Frequency Energy Harvesting System Based on Graphene for Internet of Things Applications

open access: yesInterdisciplinary Materials, Volume 5, Issue 5, Page 879-888, September 2026.
This study details a multi‐domain graphene assembled film (GAF) based radio frequency (RF) energy harvesting system (GEHS) for Internet of Things (IoT) applications. The GEHS integrates a flexible dual‐band, dual‐polarization, dual‐beam antenna array based on GAF materials with a high‐efficiency rectifier.

Semi‐Automated μCT‐Based Modeling of Vertebral Bony Endplate Microporosity and Mechanical Properties: Linking Microstructure to Inferred Mechanical Performance

open access: yesJOR SPINE, Volume 9, Issue 3, September 2026.
ABSTRACT Background The vertebral bony endplate (BEP) plays a role in regulating both mechanical load transfer and nutrient transport to the intervertebral disc, functions strongly influenced by its microstructural porosity. Variations in porosity impact bone strength, elasticity, and solute diffusion, affecting its overall mechanical competence ...

Wavelength and Full‐Polarization Encrypted Orbital Angular Momentum Meta‐Holography

open access: yesLaser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
By multiplexing three independent degrees of freedom of light, a single‐layer geometric‐phase metasurface encrypts 24 distinct holographic images across 3 wavelengths, 12 pairs of orthogonal polarizations, and 4 OAM channels, taking advantage of axial chromatic dispersion to reconstruct the color images at the same plane. ABSTRACT Multiplexing multiple

A Geometrically Regularized Gradient‐Damage Model With Orthogonality‐Based Energy Split for Dynamic Anisotropic Compression‐Shear Fracture

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 13, Page 5185-5212, September 2026.
ABSTRACT This study proposes a novel geometrically regularized gradient‐damage model for simulating dynamic mixed‐mode fracture in orthotropic materials with tension–compression asymmetry. In this model, a thermodynamic framework is formulated by incorporating damage dissipation into internal energy evolution, from which the constitutive relation and ...

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

open access: yesReviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Source Effects in Higher‐Order Ambient Seismic Field Correlations

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Ambient seismic noise interferometry is widely used for surface wave imaging. It typically requires synchronous station recordings and assumes uniform noise source distributions. Higher‐order correlations, such as the re‐correlation of the reconstructed direct waves C2 $\left({C}_{2}\right)$, enable imaging with asynchronous data and can ...

Ship‐Based GNSS Tsunami Detection: Pilot Network Demonstration

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract We demonstrate the potential for ship‐based GNSS systems to contribute to tsunami warning. We built a pilot network of 10 ships—8 commercial and 2 research vessels—equipped with a tsunami detection package consisting of a geodetic‐grade GNSS antenna and receiver, and satellite internet communications.

Comparative Field Evaluation of Active and Passive Transient‐Based Techniques for Pipeline Condition Assessment

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Hydraulic transient‐based techniques are increasingly applied for non‐intrusive condition assessment of buried water pipelines. This study presents systematic field experiments comparing active and passive approaches within the asbestos cement water supply network at the University of Canterbury.
