Nonlinear Elliptic Equations with Maximal Growth Range

Pesquimat, 2017
In this work we are interested in studying the existence of nontrivial weak solutions for a class of nonlinear elliptic equations defined in a bounded domain in dimension two, where the nonlinearities possess maximal exponential growth range motivated by

Noise suppresses or expresses exponential growth [PDF]

, 2008
In this paper we will show that noise can make a given system whose solutions grow exponentially become a new system whose solutions will grow at most polynomially.

Metastases Growth Patterns in vivo—A Unique Test Case of a Metastatic Colorectal Cancer Patient

Frontiers in Applied Mathematics and Statistics, 2019
Colorectal cancer (CRC) is one of the most common causes of cancer-related mortality worldwide. Most cases of deaths result from metastases, assumed to be shed, in many cases, before disease detection.

Global pleiotropic effects in adaptively evolved Escherichia coli lacking CRP reveal molecular mechanisms that define the growth physiology

Open Biology, 2022
Evolution facilitates emergence of fitter phenotypes by efficient allocation of cellular resources in conjunction with beneficial mutations. However, system-wide pleiotropic effects that redress the perturbations to the apex node of the transcriptional ...

Increased Abundance Coincides with Range Expansions and Phenology Shifts: A Long-Term Case Study of Two Noctuid Moths in Sweden

Diversity, 2023
Environmental and climatic changes are inducing population declines in numerous species. However, certain species demonstrate remarkable resilience, exhibiting both population growth and range expansion. This longitudinal study in Sweden carried out over

Noise expresses exponential growth under regime switching [PDF]

, 2009
Consider a given system under regime switching whose solution grows at most polynomially, and suppose that the system is subject to environmental noise in some regimes. Can the regime switching and the environmental noise work together to make the system

Blow Up and Exponential Growth to a Petrovsky Equation with Degenerate Damping

Universal Journal of Mathematics and Applications, 2021
This paper deals with the initial boundary value problem of Petrovsky type equation with degenerate damping. Under some appropriate conditions, we study the finite time blow up and exponential growth of solutions with negative initial energy.

A General Description of Growth Trends

Stats, 2022
Time series that display periodicity can be described with a Fourier expansion. In a similar vein, a recently developed formalism enables the description of growth patterns with the optimal number of parameters.
