Technical-Economic Feasibility Study of a Tri-Generation System in an Isolated Tropical Island
Over the years, and despite the energy efficiency measures and possibilities, there has been an increase in energy consumption worldwide. However, the resources and primary energies are limited and short stocked, and the energy...
Blocking dPerk in the intestine suppresses neurodegeneration in a Drosophila model of Parkinson's disease.
Parkinson's disease (PD) is characterised by selective death of dopaminergic (DA) neurons in the midbrain and motor function impairment. Gastrointestinal issues often precede motor deficits in PD, indicating that the gut-brain...

Mode Stability for the Teukolsky Equation on Extremal and Subextremal Kerr Spacetimes
Rita Teixeira da Costa
Jul 28, 2021
Abstract: We prove that there are no exponentially growing modes nor modes on the real axis for the Teukolsky equation on Kerr black hole spacetimes, both in the extremal and subextremal case. We also give a quantitative...

Hidden Spectral Symmetries and Mode Stability of Subextremal Kerr(-de Sitter) Black Holes
Abstract: We uncover hidden spectral symmetries of the Teukolsky equation in Kerr(-de Sitter) black holes, recently conjectured by Aminov, Grassi and Hatsuda (Ann. Henri Poincaré 23, 1951-1977, 2022, and Gen. Relativ. Grav....
