Solving the stochastic dynamics of population growth [PDF]

open access: yes, 2023
Population growth is a fundamental process in ecology and evolution. The population size dynamics during growth are often described by deterministic equations derived from kinetic models. Here, we simulate several population growth models and compare the

The Dynamics of Smithian Growth [PDF]

open access: yesThe Quarterly Journal of Economics, 1997
This paper analyzes the evolution of an economy where growth is driven by increased specialization caused by the geographical expansion of markets. It proves that such Smithian growth exhibits generic threshold behavior. Below a critical density of transport linkages, the economy is split into isolated local markets with limited specialization.

Human iPS cell-engineered three-dimensional cardiac tissues perfused by capillary networks between host and graft

open access: yesInflammation and Regeneration, 2018
Stem cell-based cardiac regenerative therapy is expected to be a promising strategy for the treatment of severe heart diseases. Pluripotent stem cells enabled us to reconstruct regenerated myocardium in injured hearts as an engineered tissue aiming for ...

Mathematical Modeling of Total Volatile Basic Nitrogen and Microbial Biomass in Stored Rohu (Labeo rohita) Fish

open access: yesFrontiers in Sustainable Food Systems, 2021
The paper deals with the dynamical behavior of fish volatiles and microbial growth in stored Rohu fish through mathematical modeling. Total volatile basic nitrogen (TVB-N) is formed in stored Rohu (Labeo rohita) fish due to some complicated biochemical ...

The Political Dynamics of Economic Growth [PDF]

open access: yesSSRN Electronic Journal, 2012
We argue that an understanding of the political drivers of economic growth needs an explanation of the political dynamics around the transition from one growth phase to another, and that the political drivers of early stage growth accelerations are different from that of growth maintenance.
