Objective: Observational studies suggest a potential link between obesity and constipation, but existing results are conflicting. Therefore, we conducted a Mendelian randomization (MR) study and meta-analysis to assess the causal relationship between obesity and the risk of constipation.
Methods: In this study, independent genetic variants closely related to constipation were acquired from a genome-wide association study (GWAS) to analyze the relationship between genetically predisposed obesity and the risk of constipation.
This article investigates the problem of the fully distributed self-triggered secure synchronization control for multiagent systems (MASs) under communication link denial-of-service (CLDoS) attacks. First, an algorithm for constructing a k -connected graph is designed to reduce the impact of CLDoS attacks on MASs. Based on which, a fully distributed observer-based resilient control scheme is co-designed to reduce the dependence on the communication topology information.
