Joint Decoding of Concatenated VLEC and STTC System
EURASIP Journal on Wireless Communications and Networking, 2008 We consider the decoding of wireless communication systems with both source coding in the application layer and channel coding in the physical layer for high-performance transmission over fading channels.

Transient Cytoskeletal Anisotropy Encodes Short‐Term Mechanical Memory in Glioblastoma Cells
Advanced Materials, EarlyView.The same mechanical deformation can produce distinct cytoskeletal states depending on loading history. Experiments and constitutive modeling reveal that transient actin–vimentin anisotropy stores mechanical information and governs short‐term mechanical memory in glioblastoma cells.

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells
Advanced Materials, EarlyView.Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Advanced Materials, EarlyView.We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Advanced Materials, EarlyView.A novel polar wurtzite alloy, NbAlN, is demonstrated as a transition‐metal‐containing polar barrier for GaN heterostructures. Nb atoms form coherent nanoscale enrichment within the wurtzite lattice without disrupting metal polarity. This study demonstrates that transition metals can be integrated into polar nitrides to enable polarization‐related ...
