We consider a brane N = I × S0, where S0 is an ndimensional space form, not necessarily compact, in a SchwarzschildAdS(n+2) bulk N and prove that, for specific negative pressures on the brane, the brane is an ARW space. By reflecting N and N to N̂ and N̂ , the joint branes N ∪ N̂ can be naturally embedded as a C∞hypersurface in R2 ×S0, if n is odd and if ω = − n−1 2 is chosen, a value that corresp...

We present evidence in terms of a D’Alembertain operator acting on a scalar field minus the first derivative of a potential system, with respect to an inflaton scalar field, that the Penrose model as outlined as an alternative to cosmological big crunch models gives us emergent behavior for an inflaton scalar field in early universe cosmological models. This is in contrast to the Coleman-Weinbe...

It is known that certain AdS boundary conditions allow smooth initial data to evolve into a big crunch. To study this type of cosmological singularity, one can use the dual quantum field theory, where the non-standard boundary conditions are reflected by the presence of a multi-trace potential unbounded below. For specific AdS4 and AdS5 models, we provide a D-brane (or M-brane) interpretation o...

In this paper, two universal reinforcement learning methods are considered to solve the problem of maximum power point tracking for photovoltaics. Both exhibit fast achievement MPP under varying environmental conditions and applicable in different PV systems. The only required knowledge system open-circuit voltage, short-circuit current power, all STC, which always provided by manufacturer. com...
