Tailoring configurational entropy and phase evolution in (La 0.2 Ce 0.2 Nd 0.2 Sm 0.2 Eu 0.2 ) 1 – x Bi x VO 4 ceramics for high-performance C-band dielectric resonator antennas

Abstract Achieving a near-zero temperature coefficient of resonant frequency (τf) while maintaining an ultra-high quality factor (Q×f) remains a critical challenge for microwave dielectric ceramics in next-generation 5G/6G communication systems. Herein, we report a configurationa...

Baseline direction measurement for active optical imaging systems

We propose a closed-form method for measuring the baseline direction in active optical imaging systems, including projector-camera and laser-emitter imaging configurations. The method uses two planar homographies induced by observing a planar target at different system-to-plane d...

Quality Deterioration and Volatile Metabolite Profile of ‘Orah’ Mandarin During Low-Temperature Storage and Room-Temperature Shelf Life

Low-temperature stored mandarin was prone to rapid quality deterioration when moved to a room-temperature shelf (RTS). However, systematic research on the safe threshold of time for low-temperature storage (LTS) and the key metabolic mechanisms underlying the quality deterioratio...

Station-Based Evaluation of AI Weather Models for Near-Surface Temperature, Pressure, and Wind Forecasts over Eastern Coastal China

Accurate prediction of near-surface meteorological variables is important for weather services and coastal risk management. However, the station-level performance of global artificial intelligence (AI) weather models remains insufficiently characterized in complex coastal environ...
