Fast simulation of large-scale growth models [PDF]

open access: yes, 2010
We give an algorithm that computes the final state of certain growth models without computing all intermediate states. Our technique is based on a "least action principle" which characterizes the odometer function of the growth process.

Economic Value of Selecting and Marketing Cattle by Leptin Genotype

open access: yesJournal of Agricultural and Resource Economics, 2007
Recent research has identified genetic diversity in the ability of animals to manufacture and recognize leptin, a protein that regulated appetite and weight.

Growth models on the Bethe lattice

open access: yes, 2013
I report on an extensive numerical investigation of various discrete growth models describing equilibrium and nonequilibrium interfaces on a substrate of a finite Bethe lattice.

Forecasting growth with time series models [PDF]

open access: yes, 1993
This paper compares the structure of three models for estimating future growth in a time series. It is shown that a regression model gives minimum weight to the last observed growth and maximum weight to the observed growth in the middle of the sample ...

Whiting (Merlangius merlangus) Grows Slower and Smaller in the Adriatic Sea: New Insights from a Comparison of Two Populations with a Time Interval of 30 Years

open access: yesFishes, 2023
Nowadays, overexploitation and climate change are among the major threats to fish production all over the world. In this study, we focused our attention on the Adriatic Sea (AS), a shallow semi-enclosed sub-basin showing the highest exploitation level ...

A flexible multivariable model for Phytoplankton growth

open access: yesMathematical Biosciences and Engineering, 2013
We introduce a new multivariable model to be used to studythe growth dynamics of phytoplankton as a function of both time and theconcentration of nutrients.

The Parallel Complexity of Growth Models

open access: yes, 1994
This paper investigates the parallel complexity of several non-equilibrium growth models. Invasion percolation, Eden growth, ballistic deposition and solid-on-solid growth are all seemingly highly sequential processes that yield self-similar or self ...

Agglomeration externalities and 1981-2006 regional growth in Brazil [PDF]

open access: yes, 2012
This paper focuses on manufacturing employment growth across the 26 states of Brazil. We employ the Glaeser et al. (1992) approach to identify the role played by knowledge externalities in growth and convergence.

Random Growth Models [PDF]

open access: yes, 2010
The link between a particular class of growth processes and random matrices was established in the now famous 1999 article of Baik, Deift, and Johansson on the length of the longest increasing subsequence of a random permutation.
