Gift Cards Sleeping scheme is one of the key means of saving energy for wireless sensor network.However, existing MAC protocols for underwater sensor network (UWSN) mainly focus on maximizing throughput but ignore sleeping schemes.Moreover, in existing sleeping schemes nodes wake up rapidly, which will loss the life of hardware, waste en-ergy to op
In this brief report we followed the evolution of the COVID-19 Infodemic Risk Index during Gift Cards 2020 and clarified its connection with the epidemic waves, focusing specifically on their co-evolution in Europe, South America, and South-eastern Asia.Using 640 million tweets collected by the Infodemic Observatory and the open access dataset publ
Local master equations are a widespread tool to model open quantum systems, especially in the context of many-body Bullet Tumbler systems.These equations, however, are believed to lead to thermodynamic anomalies and violation of the laws of thermodynamics.In contrast, here we rigorously prove that local master equations are consistent with thermody
