Mass as topological charge: an axiomatic framework for the equivalence principle and topological phase transitions in spiral spacetime

Abstract This paper establishes an axiomatic differential-geometric framework for spiral spacetime. Static mass is defined as a conserved flux charge of spacetime singularities. Under explicitly stated divergence-free conditions, its invariance under divergence-preserving diffeomorphisms yields a conservation-law interpretation of mass conservation with geometric-flux structure.

Abstract Evidence supporting multidisciplinary interventions for frailty in elderly cardiovascular inpatients remains limited. In this completed multicentre, single-blinded, randomised controlled trial (ChiCTR1900022623), 333 frail inpatients aged ≥ 70 years with cardiovascular diseases were randomly assigned to RENAP (Rehabilitation exercises, patient Education, Nutritional guidance, Acupoint massage, and Polypharmacy management) programme (n = 166) or usual care (n = 167).
