Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking
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.

Exploring Thermal and Mechanical Strains During Laying Down Process in Fused Filament Fabrication
This study analyzes strain evolution and thermal behavior during FFF of PLA using strain gauges and infrared imaging. Microstrain levels depend on printing conditions, with adhesion‐induced compression during cooling and peak strains in early layers. Microtomography shows minimal porosity, while thermal imaging reveals rapid heat penetration, strong ...

Teucrium polium shows antidiabetic activity with its phytochemical composition and biological activities. The essential oil is rich in carvacrol, thymol, γ‐terpinene, and o‐cymene, while the aqueous and hydroethanolic extracts are characterized by poliumoside, verbascoside, isorhamnetin‐3‐O‐rutinoside, and apigenin‐7‐rutinoside. Antioxidant activity is
