Summary: This study investigates various relay synchronization scenarios in a three-layer network, focusing on the role of the hub node and its impact on the existence of chimera states, depending on the inter-layer coupling strength and time delay. The findings include regions in the parameter plane exhibiting double chimeras and salt-and-pepper states, as well as the induction of chimera states by the hub in the absence of such states in individual layers. Additionally, the influence of link dilution between the remote layers and the hub on dynamics is examined, with the greatest effect observed when links to the coherent domain of the chimeras are removed.

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.
