Linear Optimal Signal Designs for Multi-Color MISO-VLC Systems Adapted to CCT Requirement
IEEE Access, 2018 In visible light communications (VLC), multi-color light emitting diodes (LEDs) have higher modulation bandwidth and better chromatic property compared with traditional phosphor-converted LEDs. For multi-color multi-input single-output (MISO) VLC systems,

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Map-Assisted Constellation Design for mmWave WDM With OAM in Short-Range LOS Environment
IEEE Open Journal of the Communications Society, 2023 We consider a system that integrates positioning and single-user millimeter wave (mmWave) communication, where the communication part adopts wavelength division multiplexing (WDM) and orbital angular momentum (OAM).

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
