The spatial layout and arrangement of obstacles in the built environment significantly affect its evacuation performance.However, few researchers focus on pedestrian simulation-based design optimization of built environment under emergency evacuation conditions.In this paper, we aim to evaluate the evacuation performance of optimized design solutio

Background: Reactive perforating collagenosis (RPC) is one of the rare forms of transepidermal elimination in which genetically altered collagen is extruded from the epidermis.This disease usually starts in early childhood as asymptomatic umbilicated papules on extremities, and the lesions become more conspicuous with age.Aims: The objective of our

Two related but somewhat different approaches have been proposed to formalize the notion of a self-sustaining chemical reaction network.One is the notion of collectively autocatalytic sets, formalized as RAF theory, and the other is chemical organization theory.Both formalisms have been argued to be relevant to the origin Cosmetic Bag of life.RAF s
