Cellular Identity Crisis: RD3 Loss Fuels Plasticity and Immune Silence in Progressive Neuroblastoma
Advanced Science, EarlyView.Researchers discovered that therapy‐induced loss of RD3 protein in neuroblastoma triggers a dangerous shift: cancer cells become more stem‐like, invasive, and resistant to treatment while evading immune detection. RD3 loss suppresses antigen presentation and boosts immune checkpoints, creating an immune‐silent environment.

Advanced Science, EarlyView.The size mismatch between the micropore channel and [Zn(H2O)6]2+ in porous carbon anode during the discharge process was addressed by regulating the hierarchical channel. The inducted stepwise de‐solvation of [Zn(H2O)6]2+ significantly reduced its de‐solvation energy, promoted the EDLC behavior, and strengthened the diffusion kinetic.

Guaranteed Stability of Sparse Recovery in Distributed Compressive Sensing MIMO Radar
International Journal of Antennas and Propagation, 2015 Low SNR condition has been a big challenge in the face of distributed compressive sensing MIMO radar (DCS-MIMO radar) and noise in measurements would decrease performance of radar system.
