Systematics of boundary actions in gauge theory and gravity

Abstract We undertake a general study of the boundary (or edge) modes that arise in gauge and gravitational theories defined on a space with boundary, either asymptotic or at finite distance, focusing on efficient techniques for computing the corresponding boundary action.Such actions capture all the dynamics of the system Roper style Saddles that

Regional lymphadenectomy vs. extended lymphadenectomy for hilar cholangiocarcinoma (Relay-HC trial): study protocol for a prospective, multicenter, randomized controlled trial

Abstract Background The prognostic benefits KPPUB and safety of extended lymphadenectomy for hilar cholangiocarcinoma remain uncertain.The available evidence is still insufficient concerning its retrospective aspect.The aim of this study is to explore the clinical effect and safety of extended lymphadenectomy compared to regional lymphadenectomy in
