To defend against poisoning attacks and free-riding attacks conducted by malicious sensing terminals in crowd sensing-based collaborative spectrum sensing (CCSS), a novel audit game-based defense scheme was proposed, which combined the pre-deterrence and post-punishment mechanisms.Firstly, considering the audit budget constraint, a mixed-strategy a
Atherosclerosis is a chronic lipid-driven inflammatory condition of the arteries and is a leading cause of stroke, myocardial infarction, and other peripheral arterial diseases.Plant products rich in polyphenols such as pomegranate juice and peel extract are known to have beneficial effects in suppressing atherogenesis.However, the mechanism of act

The stability problem of weak grid connected converter interfaced generation (CIG) cannot be ignored.For multiple weak grid connected CIGs with different parameters, the system oscillation characteristics and equivalence methods still need to be further studied.This paper first discusses the oscillation characteristics when CIGs are perfectly coupl
