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

Quarterly 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.

Air–sea interaction in medicanes with atmosphere–ocean–wave coupled regional climate simulations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The atmosphere–ocean–wave coupling improved storm intensity compared to standalone atmosphere setting, which tended to overestimate wind speeds. The atmosphere–ocean coupling in medicane simulations leads to increased sea surface temperatures, which enhances evaporation and promotes the development of convective systems through increased latent heat ...

Fabricating Microfluidic Co‐Cultures of Immortalized Cell Lines Uncovers Robust Design Principles for the Simultaneous Formation of Patterned, Vascularized, and Stem Cell‐Derived Adipose Tissue

Small, EarlyView.
Murphy et al present an optimized co‐culture protocol for immortalized cell line vasculogenesis. Here, immortalized co‐cultures form reproducible microvessel networks across 31‐days, while gradient microchips enable simultaneous mesenchymal stem cell (MSC) adipogenesis and endothelial cell (EC) vasculogenesis.

Discrete Laplacian Operator and Its Applications in Signal Processing

IEEE Access, 2020
Fractional calculus has increased in popularity in recent years, as the number of its applications in different fields has increased. Compared to the traditional operations in calculus (integration and differentiation) which are uniquely defined, the ...

Separation Maps for Classification of Multiple Partial Discharges: A Comparative Study Focusing on Time and Frequency Characteristics

High Voltage, EarlyView.
ABSTRACT Electrical insulation faults produce partial discharges (PD), which can be analysed to identify specific types of defects. PD clustering is a widely used method to identify PD sources, although its success depends largely on the feature maps used.

On a coupled system of fractional sum-difference equations with p-Laplacian operator

Advances in Difference Equations, 2020
In this paper, we propose a nonlocal fractional sum-difference boundary value problem for a coupled system of fractional sum-difference equations with p-Laplacian operator. The problem contains both Riemann–Liouville and Caputo fractional difference with

Reviewing seas of data: Integrating image‐based bio‐logging and artificial intelligence to enhance marine conservation

Methods in Ecology and Evolution, EarlyView.
Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

The fractional Laplacian: a primer

, 2023
In this note we give a glimpse of the fractional Laplacian. In particular, we bring several definitions of this non-local operator and series of proofs of its properties. It is structured in a way as to show that several of those properties are natural extensions of their local counterparts, with some key differences.

Fractional Laplacian with singular drift [PDF]

Studia Mathematica, 2011
For $ \in (1,2)$ we consider the equation $\partial_t u = ^{ /2} u - r b \cdot \nabla u$, where $b$ is a divergence free singular vector field not necessarily belonging to the Kato class. We show that for sufficiently small $r>0$ the fundamental solution is globally in time comparable with the density of the isotropic stable ...

Learning Metric Fields for Fast Low‐Distortion Mesh Parameterizations

Computer Graphics Forum, EarlyView.
Abstract We present a fast and robust method for computing an injective parameterization with low isometric distortion for disk‐like triangular meshes. Harmonic function‐based methods, with their rich mathematical foundation, are widely used. Harmonic maps are particularly valuable for ensuring injectivity under certain boundary conditions. In addition,
