Modeling the Epidemic Growth of Preprints on COVID-19 and SARS-CoV-2

open access: yesFrontiers in Physics, 2021
The response of the scientific community to the global health emergency caused by the COVID-19 pandemic has produced an unprecedented number of manuscripts in a short period of time, the vast majority of which have been shared in the form of preprints ...

Influence of Reproduction and Basal Area on the Increment of Euterpe edulis

open access: yesFloresta e Ambiente, 2020
The diameter increments of Euterpe edulis was characterized in order to understand the influence of reproduction and forest basal area on its growth and to represent its development through polynomial models.

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.

Modeling Quasicrystal Growth

open access: yes, 2002
Understanding the growth of quasicrystals poses a challenging problem, not the least because the quasiperiodic order present in idealized mathematical models of quasicrystals prohibit simple local growth algorithms. This can only be circumvented by allowing for some degree of disorder, which of course is always present in real quasicrystalline samples.

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.

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 ...

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 ...

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.
