Scaling laws for localised states in a nonlocal amplitude equation
It is well known that, although a uniform magnetic field inhibits the onset of small amplitude thermal convection in a layer of fluid heated from below, isolated convection cells may persist if the fluid motion within them is...

A free boundary problem arising from branching Brownian motion with selection
We study a free boundary problem for a parabolic partial differential equation in which the solution is coupled to the moving boundary through an integral constraint. The problem arises as the hydrodynamic limit of an...

The spreading speed of solutions of the non-local Fisher-KPP equation

Dec 15, 2018
We consider the Fisher–KPP equation with a non-local interaction term. In [16], Hamel and Ryzhik showed that in solutions of this equation, the front location at a large time t is 2t+o(t). We study the asymptotics of the...

A branching process with deletions and mergers that matches the threshold for hypercube percolation
We define a graph process G(p,q) based on a discrete branching process with deletions and mergers, which is inspired by the 4-cycle structure of both the hypercube Qd and the lattice Zd for large d. Individuals have Poisson...
Dynamical phase transitions in supercooled liquids
We study dynamical phase transitions in a model supercooled liquid. These transitions occur in ensembles of trajectories that are biased towards low (or high) dynamical activity. We compare two different measures of activity...

Global existence for a free boundary problem of Fisher-KPP type
Motivated by the study of branching particle systems with selection, we establish global existence for the solution of the free boundary problem when the initial condition is non-increasing with as and as . We construct the...

Investigating amorphous order in stable glasses by random pinning
We investigate stable glassy states that are found when glass-forming liquids are biased to lower than average dynamical activity. By pinning the positions of randomly chosen particles, we show that many-body correlations in...

Brownian bees in the infinite swarm limit
The Brownian bees model is a branching particle system with spatial selection. It is a system of N particles which move as independent Brownian motions in Rd and independently branch at rate 1, and, crucially, at each branching...

Origin of horsetails and the role of whole-genome duplication in plant macroevolution
Whole-genome duplication (WGD) has occurred commonly in land plant evolution and it is often invoked as a causal agent in diversification, phenotypic and developmental innovation, as well as conferring extinction resistance....

Sensitivity of bistable laminates to uncertainties in material properties, geometry and environmental conditions
Under certain conditions asymmetric composite laminates can have a bistable response to mechanical loading. A transition between the two stable states provides opportunities to produce large deflections or shape changes from...

Al(iii)-homopiperazine complexes and their exploitation for the production of polyesters
In this paper we report the synthesis and characterisation of a series of Al(iii)-homopiperazine complexes. The ortho substituent has been varied from H, Me, tBu to investigate the effect this has on the solid-state structures...
A preliminary approach to simulating cyclic variability in a port fuel injection spark ignition engine
Differences in the combustion process from one cycle to the next, termed cyclic variations, are an important feature of spark ignition engines. These variations cause fluctuations in the work output of the engine and can...

Background: The mechanisms underlying acute ERK signaling are poorly understood. Results: Feedback influences basal and acutely stimulated ERK responses but does not render signaling kinetics robust to ERK concentration....
