Finding Frequent Subgraphs and Subpaths through Static and Dynamic Window Filtering Techniques [PDF]

EAI Endorsed Transactions on Scalable Information Systems, 2020
Big data era has large volumes of data generated at high velocity from different data sources. Finding frequentsubgraphs from the graph streams can be a challenging task as streams are non-uniformly distributed andcontinuously processed. Its applications

Risk-Adaptive Dynamic Window Approach for Mobile Robot Navigation

IEEE Access
Local navigation in cluttered and dynamic environments remains a persistent challenge for mobile robots. Classical Dynamic Window Approach (DWA) planners use fixed objective weights, which makes their behavior highly sensitive to obstacle density and ...

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
