Query: Gauged Supergravities from Twisted Doubled Tori and Non-Geometric String
  Backgrounds   We propose a universal geometric formulation of gauged supergravity in terms
of a twisted doubled torus. We focus on string theory (M-theory) reductions
with generalized Scherk-Schwarz twists residing in the O(n,n) (E_{7(7)})
duality group. The set of doubled geometric fluxes, associated with the duality
twists and identified naturally with the embedding tensor of gauged
supergravity, captures all known fluxes, i.e. physical form fluxes, ordinary
geometric fluxes, as well as their non-geometric counterparts. Furthermore, we
propose a prescription for obtaining the effective geometry embedded in the
string theory twisted doubled torus or in the M-theory megatorus and apply it
for several models of geometric and non-geometric flux compactifications.
