Numerical Analysis of a Benjamin–Bona–Mahony Type Equation in a Noncylindrical Domain
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT Numerical analysis and simulation for the approximate solution of a Benjamin–Bona–Mahony type equation defined in a noncylindrical domain are presented in this article. The approximate problem is defined using the linearized Crank–Nicolson Galerkin method, which results in a linear algebraic system at each time step while maintaining quadratic

Oikos, EarlyView.Self‐organised pattern formation creates heterogeneous growth conditions in spatially extended ecosystems and can support local functional diversity in metacommunities – sets of communities linked by dispersal. However, the mechanisms connecting emergent heterogeneity on the metacommunity scale and diversity on the local scale, and how they depend on ...

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 ...

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 ...

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 ...

Weather features drive free‐tropospheric baroclinicity variability in the North Atlantic storm track
Quarterly Journal of the Royal Meteorological Society, EarlyView.We show that synoptic weather features, such as extratropical cyclones, fronts, and atmospheric rivers, contribute to more than half of the total variability of free‐tropospheric baroclinicity in the North Atlantic storm track, despite their limited spatial and temporal extent.

Distributed Leader‐Following Formation of Discrete‐Time Multi‐Agent LPV Systems
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT This paper addresses the leader‐following formation consensus problem for multi‐agent systems (MASs) with agents represented by discrete‐time linear parameter‐varying (LPV) models. The scenario where each agent can be modeled with distinct time‐varying scheduling parameters is investigated with respect to compensation signals.

Spectral Asymptotics for Fractional Laplacians [PDF]
, 2019 In this article we consider fractional Laplacians which seem to be of interest to probability theory. This is a rather new class of operators for us but our methods works (with a twist, as usual). Our main goal is to derive a two-term asymptotics as one-term asymptotics is easily obtained by R.~Seeley's method.

Direct Observation of Assembly and Function of Trigger‐Responsive Lipase Biohybrid Materials
Small Structures, EarlyView.The pH‐ and temperature‐responsive lipase‐polymer biohybrids at both supramolecular and single‐molecule levels are characterized in detail, demonstrating stimuli‐triggered reversibility, twofold higher activity, and temperature‐controlled enzymatic activity.

Resolvent kernel for the Kohn Laplacian on Heisenberg groups
Electronic Journal of Differential Equations, 2002 We present a formula that relates the Kohn Laplacian on Heisenberg groups and the magnetic Laplacian. Then we obtain the resolvent kernel for the Kohn Laplacian and find its spectral density.
