The paper addresses the issue of decentralized control with positivity constraint for impulsive interconnected switched positive systems (IISPSs) with mixed time-varying delays coexisting in the state term and the interconnection term under mode-dependent minimum dwell time (MDMDT) switching. Firstly, a positivity criterion of IISPSs is given from the aspect of sufficiency and necessity. Next, through adopting a new discretized linear copositive Lyapunov-Krasovskii functional approach, a sufficient stability criterion of IISPSs under MDMDT constraint is presented. Then, utilizing the method of matrix decomposition, for the mode-dependent controller gains, a valid decentralized controller design scheme in the mode-dependent piece-wise form with formulated linear programming (LP) condition is given for IISPSs under MDMDT constraint. Furthermore, the proposed decentralized control design can degenerate into the one for the case that mixed delay does not lie in IISPSs. At last, three examples are presented to verify the validity of decentralized control design.

Conventional personal health record (PHR) management systems are centralized, making them vulnerable to privacy breaches and single points of failure. Despite progress in standardizing healthcare data with the FHIR format, hospitals often lack efficient platforms for transferring PHRs, leading to redundant tests and delayed treatments. To address these challenges, we propose a decentralized PHR management system leveraging Personal Data Stores (PDS) and Decentralized Identifiers (DIDs) in line with the Web 3.

Digital platforms have significantly transformed the labor market, particularly in the gig economy. Despite this issue's growing importance, no systematic literature review has explicitly examined the influence of digital platforms on gig workers. This study fills this gap by conducting a comprehensive review of 18 articles out of 81 published between 2019 and 2023, retrieved from the Scopus and Web of Science databases, using the PRISMA framework.

Background: Past studies associating personality with psychosis have been limited by small nonclinical samples and a focus on general symptom burden. This study uses a large clinical sample to examine personality's relationship with psychosis-specific features and compare personality dimensions across clinically and neurobiologically defined categories of psychoses.
Methods: A total of 1352 participants with schizophrenia, schizoaffective disorder, and bipolar with psychosis, as well as 623 healthy controls (HC), drawn from the Bipolar-Schizophrenia Network for Intermediate Phenotypes (BSNIP-2) study, were included.
