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.

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 ...

Frequency Shaping for Improving a Trade‐Off Between Control and Privacy Performance: Beyond Differential Privacy

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In privacy protection of control systems, a trade‐off between control performance and privacy level is often pointed out. Our goal in this paper is to improve this trade‐off by shaping the frequency of noise added for privacy protection when the control objective is to track a reference signal, which is taken as a piece of information whose ...
