Model for striped growth [PDF]

open access: yesPhysical Review E, 2004
We introduce a model for describing the defected growth of striped patterns. This model, while roughly related to the Swift-Hohenberg model, generates a quite different mixture of defects during phase ordering. We find two characteristic lengths in the system: the scaling length L(t), and the average width of the domain walls.

Closing the Phenotyping Gap: High Resolution UAV Time Series for Soybean Growth Analysis Provides Objective Data from Field Trials

open access: yesRemote Sensing, 2020
Close remote sensing approaches can be used for high throughput on-field phenotyping in the context of plant breeding and biological research. Data on canopy cover (CC) and canopy height (CH) and their temporal changes throughout the growing season can ...

Roughening in Nonlinear Surface Growth Model

open access: yesApplied Sciences, 2020
The aim of this paper is to examine the coarsening process in the evolution of the surface morphology during molecular beam epitaxy (MBE). A numerical approach for modeling the evolution of surface roughening in film growth by MBE is proposed.

Foreign capital in a growth model [PDF]

open access: yes, 2007
Within an endogenous growth framework, this paper empirically investigates the impact of financial capital on economic growth for a panel of 60 developing countries, through the channel of domestic capital formation. By estimating the model for different

On a Boltzmann mean field model for knowledge growth [PDF]

open access: yes, 2016
In this paper we analyze a Boltzmann type mean field game model for knowledge growth, which was proposed by Lucas and Moll [15]. We discuss the underlying mathematical model, which consists of a coupled system of a Boltzmann type equation for the agent ...

Population, immigration and growth in a Romer endogenous growth model [PDF]

open access: yes, 2018
Producción CientíficaEndogenous growth theory has not yet consistently incorporated population growth or immigration into its models. As a result, in the present day, there is no universally accepted endogenous growth model explaining the empirical ...

A model of growth through creative destruction [PDF]

open access: yes, 1990
This paper develops a model based on Schumpeter's process of creative destruction. It departs from existing models of endogenous growth in emphasizing obsolescence of old technologies induced by the accumulation of knowledge and the resulting process or ...

A Growth Model for Multicellular Tumor Spheroids [PDF]

open access: yes, 2003
Most organisms grow according to simple laws, which in principle can be derived from energy conservation and scaling arguments, critically dependent on the relation between the metabolic rate B of energy flow and the organism mass m.
