Positive solutions for the one-dimensional Sturm-Liouville superlinear p-Laplacian problem

open access: yesElectronic Journal of Differential Equations, 2018
We prove the existence of positive classical solutions for the p-Laplacian problem $$\displaylines{ -(r(t)\phi (u'))'=f(t,u),\quad t\in (0,1), \cr au(0)-b\phi ^{-1}(r(0))u'(0)=0,\ cu(1)+d\phi ^{-1}(r(1))u'(1)=0, }$$ where $\phi (s)=|s|^{p-2}s$, $p ...

A conservative numerical scheme for the multilayer shallow‐water equations on unstructured meshes

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
An energy‐conserving scheme is derived for the multilayer shallow water model, making use of the direct connection between energy conservation and the skew symmetry of the Poisson bracket for the model. A new mechanism is proposed to prevent layer interface outcropping.

Existence of nontrivial solutions for singular quasilinear equations with sign changing nonlinearity

open access: yesElectronic Journal of Differential Equations, 2010
By an application of Bonanno's three critical point theorem, we establish the existence of a nontrivial solution to the problem $$displaylines{ -Delta_p u= mu frac{g(x)|u|^{p-2}u}{|x|^p} +lambda a(x)f(u) quad hbox{in }Omega,cr u =0quad hbox{on ...

Global representation of extratropical cyclone precipitation and future trends in CMIP6 models

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We use a cyclone‐tracking algorithm to study precipitation produced by extratropical cyclones and identify five global hotspots of extreme precipitation: the well‐known Pacific and Atlantic storm tracks in the Northern Hemisphere and three distinct hotspots in the Southern Hemisphere, located at low latitudes to the east of the major landmasses of ...

Toward Useful Quantum Kernels

open access: yesAdvanced Quantum Technologies, EarlyView.
The hybrid approach to Quantum Supervised Machine Learning is compatible with Noisy Intermediate Scale Quantum (NISQ) devices but hardly useful. Pure quantum kernels requiring fault‐tolerant quantum computers are more promising. Examples are kernels computed by means of the Quantum Fourier Transform (QFT) and kernels defined via the calculation of ...
