Adaptive Differential Space-Time-Spreading-Assisted Turbo-Detected Sphere Packing Modulation [PDF]
, 2007 In this contribution a novel adaptive differential space-time spreading assisted turbo detected sphere packingmodulation scheme is proposed for improving the achievable throughput of code division multiple access (CDMA) systems.

Asymptotic behaviours of stochastic differential delay equations [PDF]
, 2006 Most of the existing results on stochastic stability use a single Lyapunov function, but we shall instead use multiple Lyapunov functions in this paper.

Asymptotic states for kink–meson scattering
European Physical Journal C: Particles and Fields, 2023 The definition of a quantum state corresponding to a wave packet far from a global soliton is considered. We define an asymptotic quantum state corresponding to a localized wave packet of elementary quanta far from a kink.

Asymptotic behaviors for nonlocal diffusion equations about the dispersal spread [PDF]
Analysis and Applications, 2020 This paper studies the effects of the dispersal spread, which characterizes the dispersal range, on nonlocal diffusion equations with the nonlocal dispersal operator [Formula: see text] and Neumann boundary condition in the spatial heterogeneity environment.

Asymptotic behavior of solutions of a Fisher equation with free boundaries and nonlocal term
Electronic Journal of Qualitative Theory of Differential Equations, 2019 We study the asymptotic behavior of solutions of a Fisher equation with free boundaries and the nonlocal term (an integral convolution in space). This problem can model the spreading of a biological or chemical species, where free boundaries represent ...

Exact hydrodynamic solution of a double domain wall melting in the spin-1/2 XXZ model
SciPost Physics, 2022 We investigate the non-equilibrium dynamics of a one-dimensional spin-1/2 XXZ model at zero-temperature in the regime $|\Delta|< 1$, initially prepared in a product state with two domain walls i.e, $|\downarrow\dots\downarrow\uparrow\dots\uparrow ...

Minimal wave speed of competitive lattice dynamical systems with delays
Advances in Difference Equations, 2018 This paper deals with the minimal wave speed of delayed lattice dynamical systems. We obtain the minimal wave speed by presenting the existence and nonexistence of traveling wave solutions, which completes the earlier results.

Spatial assortment of mixed propagules explains the acceleration of range expansion. [PDF]
PLoS ONE, 2014 Range expansion of spreading organisms has been found to follow three types: (i) linear expansion with a constant rate of spread; (ii) bi-phase expansion with a faster linear expansion following a slower linear expansion; and (iii) accelerating expansion
