A Novel Approach to Integrate Differential Modulation With OTFS Systems Over mmWave UAV Channels

IEEE Access
Orthogonal time frequency space (OTFS) modulation designed for highly dynamic millimeter-wave (mmWave) channels, has the advantage of converting time-varying channels into quasi-static representations in the delay–Doppler (DD) domain, making it ...

Bifunctional Artificial Enzymes‐Loaded Microgels With LOX‐ and CAT‐Like Activities for Metabolic Reprogramming and Scarless Wound Repair

Advanced Science, Volume 13, Issue 27, 13 May 2026.
A bifunctional lactate oxidase‐like and catalase‐like artificial enzyme (Metazyme) is integrated into a rod‐shaped microgel (MetaRgel) to enable cascade lactate oxidation and oxygen regeneration. By reprogramming the wound metabolic microenvironment, MetaRgel alleviates excessive lactate accumulation, oxidative stress, hypoxia, and inflammation ...
