Bridging dimensions: General embedding algorithm and field-theory reconstruction in 5D braneworld models
T Nakas, TD Pappas, Z Stuchlík - Physical Review D, 2024 - APS
We develop a general algorithm that enables the consistent embedding of any four-
dimensional static and spherically symmetric geometry into any five-dimensional single …

Health care expenditures and longevity: is there a Eubie Blake effect?
It is still an open question whether increasing life expectancy as such causes higher health
care expenditures (HCE) in a population. According to the “red herring” hypothesis, the …

New black-string solutions for an anti–de Sitter brane in scalar-tensor gravity
We consider a five-dimensional theory with a scalar field nonminimally coupled to gravity,
and we look for novel black-string solutions in the bulk. By appropriately choosing the …

[HTML][HTML] Localized brane-world black hole analytically connected to an AdS5 boundary
We construct from first principles the geometry of an analytic, exponentially localized five-
