Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking

Laser &Photonics Reviews, Volume 20, Issue 10, 22 May 2026.
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Naked‐Eye Visual Warning of ppmv‐Level Fault‐Free Humidity Upper Limit

Advanced Science, Volume 13, Issue 14, 9 March 2026.
In this study, based on the urgent need in many critical fields for ppmv‐level fault‐free humidity upper limit (ppmv‐FFHUL) monitoring, an innovative threshold gated humidity sensing technology was developed. It exhibits superior portability (as thin and light as paper) and highly economic feature (without auxiliary instruments at all), and can achieve

Estimation of Compressive Strength of High‐Performance Concrete Using Hybrid Optimization of Neural Networks and Metaheuristic Algorithms (GWO, BA, WOA)

Journal of Engineering, Volume 2026, Issue 1, 2026.
High‐performance concrete (HPC) is widely used in modern infrastructure due to its superior mechanical properties, durability, and long‐term performance. However, accurately predicting its compressive strength remains a challenging task because of the complex nonlinear relationships among concrete mixture components.

M2 Macrophages are Major Mediators of Germline Risk of Endometriosis and Explain Pleiotropy With Comorbid Traits

Advanced Science, Volume 12, Issue 41, November 6, 2025.
Genes associated with endometriosis risk are highly expressed in M2 macrophages, particularly ligands IL1A and IL1B. Endometrial‐type epithelium and stroma are likely recipients of these ligands. While IL1B treatment disturbs epithelial organization, blockage of the signaling results in a dose‐dependent decrease in spontanesous and evoked pain, reduces
