An interesting idea is that the universe could be spontaneously created from nothingbut no rigorousproof has been given. In this paperwe present such a proof based on the analytic solutions of the Wheeler-DeWitt equation (WDWE). Explicit solutions of the WDWE for the special operator ordering factorp= -2 (or 4) show thatonce a small true vacuum bubble is created by quantum fluctuations of themetastable false vacuumit can expand exponentially no matter whether the bubble is closed,flat,or open… 
Inflation of small true vacuum bubble by quantization of Einstein-Hilbert action
We study the quantization of the Einstein-Hilbert action for a small true vacuum bubble without matter or scalar field. The quantization of action induces an extra term of potential called quantum
The Universe as a Graviton Condensate: The “Dark-Bright Conjecture”
The idea of a homogeneous, isotropic and spatially flat universe brings with it some unresolved issues, such as the nature of dark matter and the “coincidence problem”, i.e. the same order of
A universe from nothing or big bounce ?
The beginning of the universe is explained by many theoretical aspects. The cosmological evolution begins with the singularity. Such singularities predict the initial conditions of the universe. To
Quantum relativistic cosmology: Dynamical interpretation and tunneling universe
In this work the wave functions associated to the quantum relativistic universe, which is described by the Wheeler-DeWitt equation, are obtained. Taking into account different kinds of energy
An Alternative Approach to Estimate the Vacuum Energy Density of Free Space
According to the current understanding, the recently observed accelerated expansion of the universe is caused by the dark or the vacuum energy. Attempts to calculate the magnitude of this energy
Quantization of the interior of the black hole
In this work we study the Schwarzschild metric in the context of canonical quantum gravity inside the horizon, close of horizon and near the black hole singularity. Using this standard quantization
Classical and quantum cosmology with York time
We consider a solution to the problem of time in quantum gravity by deparameterization of the ADM action in terms of York time, a parameter proportional to the extrinsic curvature of a spatial
Power law expansion of the early universe for a V (a) = kan potential
In a recent paper, He, Gao and Cai [Phys. Rev. D 89, 083510 (2014)], found a rigorous proof, based on analytical solutions of the Wheeler–DeWitt (WDWE) equation, of the spontaneous creation of the

TLDR
The objective of the current work is to present the results of several numerical simulations of pulsatile blood flow in healthy and diseased arteries and compare with clinical expectations to ensure the simulations stay realistic and reliable for clinicians.
