The Weakly Pushed Nature of "Pulled" Fronts with a Cutoff [PDF]

, 2001
The concept of pulled fronts with a cutoff $\epsilon$ has been introduced to model the effects of discrete nature of the constituent particles on the asymptotic front speed in models with continuum variables (Pulled fronts are the fronts which propagate ...

Resource Allocation in Low Density Spreading Uplink NOMA via Asymptotic Analysis [PDF]

2020 IEEE International Symposium on Information Theory (ISIT), 2020
Low density spreading non-orthogonal multiple- access (LDS-NOMA) is considered where K single-antenna user equipments (UEs) communicate with a base station (BS) over F fading sub-carriers. Each UE k spreads its data symbol over d k k , ∀k as design parameters, we characterize the resource allocation solutions that closely maximize the ergodic mutual ...

On a Multistable Type of Free Boundary Problem with a Flux at the Boundary

Advances in Mathematical Physics, 2023
This paper studies the free boundary problem of a multistable equation with a Robin boundary condition, which may be used to describe the spreading of the invasive species with the solution representing the density of species and the free boundary ...

Two-dimensional quantum walk under artificial magnetic field [PDF]

, 2015
We introduce the Peierls substitution to a two-dimensional discrete-time quantum walk on a square lattice to examine the spreading dynamics and the coin-position entanglement in the presence of an artificial gauge field.

Damage spreading transition in glasses: a probe for the ruggedness of the configurational landscape [PDF]

, 1999
We consider damage spreading transitions in the framework of mode-coupling theory. This theory describes relaxation processes in glasses in the mean-field approximation which are known to be characterized by the presence of an exponentially large number ...

The asymptotic nature of the analytic spread [PDF]

Mathematical Proceedings of the Cambridge Philosophical Society, 1979
In (3), corollary, p. 373) Burch gives the following inequality for the analytic spread l(I) of an ideal I of a noetherian local ring (R, m):In this paper we shall improve this by showing that the number min depth (R/In) may be replaced by the asymptotic value of depth (R/In) for large n (which exists) (see Section (2)). By its definition (see (6), def.

Dynamics for a Ratio-Dependent Prey–Predator Model with Different Free Boundaries

Mathematics
In this paper, we study the dynamics of the ratio-dependent type prey–predator model with different free boundaries. The two free boundaries, determined by prey and predator, respectively, implying that they may intersect with each other as time evolves,

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.
