Diabetic Retinopathy in Primary Healthcare in a Brazilian Municipality: A Cross‐Sectional Study Using Teleophthalmology

open access: yesHealth Care Science, EarlyView.
The prevalence of diabetic retinopathy was estimated to be 28.3% (95% CI 21.1–35.4), with most of the cases corresponding to mild non‐proliferative diabetic retinopathy. ABSTRACT Background Diabetic retinopathy is a complication of diabetes and the leading cause of irreversible blindness in people of working age.

Intrinsic chiroptical responsivity in self‐powered organic photodiodes for polarization‐tunable optical convolution

open access: yesInfoMat, EarlyView.
Self‐powered chiral organic photodiodes function as polarization‐sensitive convolutional filters for circularly polarized light‐driven optical convolutional neural networks. This conceptually innovative architecture enables dynamic weight modulation, bias‐free operation, and exceptional noise resilience, boosting feature extraction fidelity from 0.15 ...

Enhancing spatial cognition through origami training: Insights from brain connectomes

open access: yesJournal of Intelligent Medicine, EarlyView.
Origami training enhances spatial cognition via measurable brain network changes (EEG/eye‐tracking). The mental rotation and folding tasks validate these gains. This low‐cost method offers a scalable intervention for cognitive decline. Abstract Spatial cognition is a key ability of human cognition and intelligence.

How Well Do CMIP6 Models Simulate the Influence of the West African Westerly Jet on Sahel Precipitation?

open access: yesInternational Journal of Climatology, EarlyView.
Climate models generally reproduce the WAWJ and August peak but simulate its onset prematurely and too strongly relative to ERA5. CMIP6 simulations struggle to reproduce the jet–precipitation relationship in the Sahel and underrepresent associated moisture transports.

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

open access: yesLaser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.
