Amblyopia is, aside from refractive error, the most common cause of visual loss in children. Thus amblyopia is a serious public health issue. When diagnosed and treated early, the visual losses may be easily reversed.

Observation of elliptical rings in Type-I spontaneous parametric down-conversion
We investigate the transverse spatial profile of down-converted light produced by noncollinear, degenerate, Type-I spontaneous parametric down-conversion in two types of nonlinear crystals.

This study evaluates the scalability of PQD GNC‐based LSCs for BIPV applications. Experimental data and Monte Carlo simulations predict performance up to 1 m2, achieving a peak power conversion efficiency of 3.17%. The results confirm the viability of these LSCs for energy‐efficient building applications.

Rapid Diagnostics of Reconfigurable Intelligent Surfaces Using Space‐Time‐Coding Modulation
A fast reconfigurable‐intelligent‐surface (RIS) diagnostics method is proposed based on spatio‐temporal modulation with orthogonal codes. Theoretical analysis demonstrates a clear distinction in code channel power between normal and faulty elements. Simulations validate its feasibility under high fault ratios and varying receiving angles.

3D Concrete Printing of Triply Periodic Minimum Surfaces for Enhanced Carbon Capture and Storage
A 3D‐printable and carbon‐capturing concrete is developed by replacing cement with diatomaceous earth (DE), which enhances rheology, provides hierarchical porosity, and serves as a nucleation site for carbonation. Maximum absorption of 488.7 gCO2 kgcement−1 is achieved in 7 days, a 142% increase over conventional concrete, and the triply periodic ...

Thermal Expansion Behavior of PM6 Studied Using In Situ Wide‐Angle X‐Ray Scattering
In organic photovoltaics, small morphological changes can significantly impact performance. This study examines the thermal expansion of PM6 using in situ WAXS and GIWAXS from 30 to 300 °C. By analyzing samples of increasing complexity, factors like initial anisotropic nanoscale arrangements and substrate mismatches are quantified, revealing systematic
