We consider quantum effects of gravitational and electromagnetic fields in spherically symmetric black hole spacetimes the asymptotic safety scenario. Introducing both running couplings from renormalization group equations applying a physically sensible scale identification scheme based on Kretschmann scalar, we construct mechanically corrected, or improved Reissner-Nordstrom metric. study glob...

alzheimer's disease (ad) is a progressive neurodegenerative disease characterized by memory and cognitive dysfunction due to neuronal cell loss in higher brain centers. senile plaques containing amyloid β (aβ) are associated with this disease as well as a reduction in cholinergic neuron numbers. tacrine is a reversible cholinesterase inhibitor in clinical use to treat moderate forms of ad. chit...

Hamiltonian Monte Carlo (HMC) exploits Hamiltonian dynamics to construct efficient proposals for Markov chain Monte Carlo (MCMC). In this paper, we present a generalization of HMC which exploits non-canonical Hamiltonian dynamics. We refer to this algorithm as magnetic HMC, since in 3 dimensions a subset of the dynamics map onto the mechanics of a charged particle coupled to a magnetic field. W...
