By not only relying on the initial state but also relying on states before, the principle of a self-retrospect dynamic system has been developed to represent the changes in grandpas best a system since 1991.Afterward, the periphery theory was established, which studies the boundary of a system.We try to integrate the principle of the self-retrospec

Abstract Background Contracts can be an effective lever to implement and manage health-enabling food retail environments.However, guidance for the effective use of contracts in food retail settings is limited.The use of contracts to create healthy food vending environments is one area where policy attention has been focussed in high income countrie

Brain development and function are highly reliant on adequate establishment and maintenance of vascular networks.Early impairments in vascular health can impact brain maturation and energy metabolism, which may lead to neurodevelopmental anomalies.Our recent work not only provides novel insights into the development of cerebrovascular networks but
