Fronthaul evolution: From CPRI to Ethernet [PDF]

, 2015
It is proposed that using Ethernet in the fronthaul, between base station baseband unit (BBU) pools and remote radio heads (RRHs), can bring a number of advantages, from use of lower-cost equipment, shared use of infrastructure with fixed access networks,

Engineering MnPt Bimetallic Nanozymes for Cascade Enzymatic Therapy and Enhanced Radio‐Immunotherapy

Advanced Science, EarlyView.
A CD44‐targeted MnPt bimetallic nanozyme (HD@MnO2) integrates multienzyme‐like activity with cGAS–STING activation to boost radio‐immunotherapy. Through cascade biocatalysis, it depletes glutathione, relieves hypoxia, and amplifies ROS, enhancing radiotherapy‐induced DNA damage and immunogenic cell death. The nanozyme promotes dendritic cell maturation
