To address the increasingly serious parking pain, numerous mobile Apps have emerged to help drivers find a convenient spot with various auxiliary information. However, phenomenon of "multiple cars chasing same spot" still exists, especially for on-street parking. Existing reservation-based resource allocation solutions could competition issue some extent, but it is impractical treat all spots as reservable resources. This paper first conducts qualitative investigation based on online survey...

Objective.A percutaneous left ventricular assist device (PLVAD) can be used as a bridge to heart transplantation or temporary support for end-stage failure. Transvalvularly placed PLVADs may result in aortic regurgitation due unstable pump position during fully supported operation, which diminish the pumping effect of forward flow and predispose complications. Therefore, accurate characterization is essential proper modeling heart-pump interactions validation control strategies.Approach.In...

Personalized federated learning (PFL) framework that targets individual models for optimization provides better privacy and flexibility clients. However, in challenging intelligent sensing applications, the heterogeneous client’s data distributions make aggregation of local server unstable or even hard to converge. To deal with performance degradation caused by above problem, existing PFL methods focus more on how fine-tune global model but ignore impact fusion algorithm results. In this...
