Metasurface‐Based Polarization‐Controlled Generation of 128‐Dimensional Vector Vortex Combs

open access: yesLaser &Photonics Reviews, EarlyView.
The generation and continuous control of 128‐dimensional vector vortex combs using a single metasurface is reported. This work creates a class of structured light that uniquely integrates ultrahigh dimensionality with vector properties, and represents a crucial step toward on‐chip, reconfigurable generators for ultrahigh‐dimensional vector structured ...

Comparative Effects of Angiotensin Receptor Blockers on Blood Pressure and Serum Urate in Patients With Hypertension and Hyperuricaemia: A Systematic Review and Network Meta‐Analysis

open access: yesMedicine Bulletin, EarlyView.
Allisartan ranked best for serum urate reduction and showed favourable blood pressure control, whereas losartan also performed well overall. These rankings may inform ARB selection but should be interpreted cautiously because of inconsistency, heterogeneity and sparse direct evidence.

Breaking Extrapolation Barriers: Dual Innovations for Property and Component Design of Multi‐Component Alloy

open access: yesMaterials Genome Engineering Advances, EarlyView.
This study breaks extrapolation barriers in alloy design by merging symbolic regression with latent space sampling. The dual‐strategy framework enables accurate prediction of high‐hardness properties and navigates uncharted compositional spaces. The approach successfully designs novel high‐entropy alloys with hardness exceeding 863.5 HV, demonstrating ...

Fast Reconstruction of Motion‐Corrupted Data With Mobile‐GRAPPA: Motion and δB0$$ \delta {B}_0 $$ Inhomogeneity Correction Leveraging Efficient GRAPPA

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an accurate and computationally efficient motion‐corrected MRI reconstruction framework that incorporates hundreds to thousands of motion and δB0$$ \delta {B}_0 $$ estimates from high‐temporal‐resolution tracking. Methods We propose Mobile‐GRAPPA, a k‐space preprocessing approach that uses MLP‐parameterized local GRAPPA ...

Association of Nasal Anatomy, Airflow, and Surgery With Olfactory Outcomes: A State‐of‐the‐Art Review

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Olfactory function is influenced by nasal airflow dynamics and anatomical variations within the nasal cavity. This narrative review evaluates how nasal anatomy and airflow relate to olfactory outcomes, with a particular focus on olfactory changes following functional nasal surgery. Data Sources PubMed.

Coverage‐based rarefaction fails to quantify relative species richness

open access: yesOikos, EarlyView.
Coverage‐based rarefaction (CBR) is a high‐profile tool for assessing biodiversity that provides relative species richness estimates by leveraging the Good‐Turing index u to interpolate. In contrast to alternatives such as the Shannon and Simpson indices, CBR's main appeal is providing values in units of species. CBR is tested against a series of other

Quantitative Evaluation of Surface Whitening Mitigation via Thermal Annealing in Carbon Fiber/Polyphenylene Sulphide Thermoplastic Composite Laminates

open access: yesPolymer Composites, EarlyView.
Mitigation of surface whitening in CF/PPS laminates via thermal annealing and quantitative image‐based assessment. ABSTRACT Surface whitening is a manufacturing‐induced surface defect in thermoplastic composites, resulting from non‐uniform shrinkage and near‐surface resin instability during cooling.

Structural Performance of Hybrid Fiber–Metal Laminates Reinforced With Natural and Synthetic Fibers: Tensile, Dynamic–Mechanical, and Residual Stress Behavior

open access: yesPolymer Composites, EarlyView.
Hybrid fiber‐metal laminates combining aluminum with carbon, glass, and sisal/epoxy layers. Sisal fibers maintained strength, improved strain and thermal stability, and reduced residual stresses with less synthetic fiber. ABSTRACT This work studied how hybridization between natural and synthetic fibers influences the structural tensile performance ...

Radiation Shielding Performance of B4C‐Reinforced Ultra‐High Molecular Weight Polyethylene Composites Against Low‐Energy X‐Rays: Experimental and Computational Analysis

open access: yesPolymer Composites, EarlyView.
Radiation shielding behavior of B4C‐reinforced UHMWPE composites. ABSTRACT The present study investigates the radiation shielding performance of ultra‐high molecular weight polyethylene (UHMWPE) composites reinforced with varying boron carbide (B4C) contents against low‐energy X‐rays through combined experimental and computational approaches.

Recycling of Thermoplastic Unidirectional Tapes: An Image‐Analysis Method for Measuring Residual Glass‐Fiber Length in Convoluted Fiber Clusters

open access: yesPolymer Composites, EarlyView.
Development of a rapid, low‐cost method for measuring residual glass fibre length: samples are collected by tweezers, prepared via submersion, imaged with a flatbed scanner as a cost‐effective alternative to microscopy, and analyzed for fibre length independently of image acquisition.
