Although ignition had been achieved at the National Ignition Facility(NIF),recent observations of the experiments indicate novel physics that beyond theoretical predictions emerge,e.g.,the neutron analysis of experime...
Graph burning is a model for describing the spread of influence in social networks and the generalized burning number br(G)of graph Gis a parameter to measure the speed of information spread on network G. In this pape...
Objective: To explore the clinical efficacy of the Jing ethnic group’s self-proposed formula combined with burning mugwort on patients after cholecystectomy for gallstones. Methods: Sixty-four patients with gallstone...
Objective:To describe the clinical fea-tures of delayed post-hypoxic leukoencephalopathy after smoke inhalation from dry burning.Methods:We col-lected the clinical history and examination data of a pa-tient who presen...
