Asymptotics of solutions of nonlinear parabolic equations
Journal of Differential Equations, 2003 The paper is concerned with the large time behaviour of solutions to the Cauchy problem for the nonlinear parabolic equations \[ u_t = \Delta u + F(u, D_x u, D^2_x u), \qquad u \in \mathbb R^n,\;x \in \mathbb R^N, t > 0 \] with initial data \[ u(0,x) = u_0(x), \qquad x \in \mathbb R^N,\;N \geq 1, \] \(F\) being a sufficiently smooth vector-valued ...

Multicontinuum Homogenization for Poroelasticity Model
International Journal for Numerical Methods in Fluids, EarlyView.This work derives a generalized multicontinuum poroelasticity model using the multicontinuum homogenization method to enable accurate coarse‐grid simulations of coupled flow–mechanics processes in highly heterogeneous porous media. Coupled constraint cell problems are formulated, and the corresponding multicontinuum equations are rigorously derived ...

Fujita-type results for the degenerate parabolic equations on the Heisenberg groups [PDF]
In this paper, we consider the Cauchy problem for the degenerate parabolic equations on the Heisenberg groups with power law non-linearities. We obtain Fujita-type critical exponents, which depend on the homogeneous dimension of the Heisenberg groups ...

Time‐Varying Skewness–Kurtosis Dynamics in Bitcoin Markets
Journal of Futures Markets, EarlyView.ABSTRACT This paper examines the relationship between skewness and kurtosis in Bitcoin spot and futures markets using high‐frequency data. We document a strong convex skewness–kurtosis relationship consistent with theoretical moment restrictions. Trading activity is positively associated with realized kurtosis, particularly in futures markets, though ...

Review of millimeter‐wave and terahertz near‐field synthetic aperture radar imaging technology
InfoScience, EarlyView.Abstract This paper comprehensively reviews the development of millimeter‐wave (MMW) and terahertz (THz) near‐field imaging technologies, with an emphasis on the state of synthetic aperture radar (SAR)‐based imaging technologies. Near‐field imaging technologies are categorized into passive and active imaging modes, among which active imaging is favored

A dynamical inverse problem for a parabolic equation [PDF]
Opuscula Mathematica, 2006 A problem of dynamical reconstruction of unknown distributed or boundary disturbances acting upon nonlinear parabolic equations is discussed. A regularized algorithm which allows us to reconstruct disturbances synchro with the process under consideration

Analysis of a reaction-diffusion system of ƛ -w type [PDF]
, 2003 The author studies two coupled reaction-diffusion equations of 'ƛ - w' type, on an open, bounded, convex domain Ω C R(^d) (d ≤ 3), with a boundary of class C(^2), and homogeneous Neumann boundary conditions.
