Advanced Science, EarlyView.Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...

Quantifying Temporal Decorrelation over Boreal Forest at L- and P-band [PDF]
, 2008 Temporal decorrelation is probably the most critical factor towards a successful implementation of Pol-InSAR parameter inversion techniques in terms of repeat-pass InSAR scenarios. In this paper the effect and impact of temporal decorrelation at L- and P-

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits
Advanced Science, EarlyView.This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Advanced Science, EarlyView.A flexible, hexagonally packed artificial dielectric providing a wide range of effective permittivities (εr ≈ 30–1400) without lumped elements was developed for clinical and ultra‐high‐field MRI. Combined with modular passive‐dipole arrays, the system enables adaptable RF field shaping through electric‐ and magnetic‐dipole tuning.

Advanced Science, EarlyView.Sun et al. report a self‐assembling trimeric subunit vaccine platform termed RHS, which integrates the JN.1 receptor‐binding domain (RBD) with the heptad repeat 1 (HR1), stem helix (SH), and heptad repeat 2 (HR2) regions. The SARS‐CoV‐2 RHS vaccine elicits variant‐reactive RBD‐specific antibodies and cross‐reactive SH‐specific antibodies against ...
