Reversible protonic ceramic electrochemical cells (R-PCECs) are a promising option for efficient and low-cost generation of electricity hydrogen. Commercialization R-PCECs, however, hinges on the development highly active robust air electrodes. Here, we report an electrode consisting PrBa0.8Ca0.2Co2O5+δ in situ exsolved BaCoO3−δ nanoparticles (PBCC–BCO) that shows minimal polarization resistance (∼0.24 Ω cm2 at 600 °C) high stability when exposed to humidified with 3−50% H2O. An R-PCEC...

Simulation experimental results computer‐controlled are illustrated show validity practical...
Federated learning allows multiple clients to collaboratively train a global model with the assistance of server. However, its distributed nature makes it susceptible poisoning attacks, where malicious can compromise by sending harmful local updates To unlearn an accurate from poisoned one after identifying clients, federated unlearning has been introduced. Yet, current research on primarily concentrated effectiveness and efficiency, overlooking security challenges presents. In this work, we...
In this paper, we investigate an accurate synchronization between a physical network and its digital twin (DNT), which serves as virtual representation of the network. The considered includes set base stations (BSs) that must allocate limited spectrum resources to serve users while also transmitting partially observed information cloud server generate DNT. Since DNT can predict status based on historical status, BSs may not need send their at each time slot, allowing them conserve users....

Coherent beam combination offers a solution to the challenges associated with power handling capacity of individual fibres, however, combined intensity profile strongly depends on relative phase each fibre. Optimal necessitates precise control over fibre channel, determining required compensations is challenging because information typically not available. Additionally, presence continuously varying noise in laser systems means that single-step and high-speed correction process required. In...

Abstract Coherent beam combination has emerged as a promising strategy for overcoming the power limitations of individual fibre lasers. This approach relies on maintaining precise phase difference between constituent beamlets, which are typically established using retrieval algorithms. However, locking is often studied under assumption that levels beamlets remain stable, an idealisation does not hold always in practical applications. Over operational lifetime lasers, degradation inevitably...
