Postoperative cognitive dysfunction (POCD) is a frequent complication after surgery, particularly among older adults, and its underlying mechanisms remain incompletely understood. Brain-derived neurotrophic factor (BDNF) is a key regulator of neuronal survival and synaptic plasti…

Decentralized federated learning (DFL) removes the central server by letting nodes exchange model updates through peer-to-peer gossip, but existing gossip-based methods often lack provenance finality and resilience to Byzantine or lazy participants. Ledger-assisted federated lear…
