The idea that there are any large-scale trends in the evolution of biological organisms is highly controversial. It is commonly believed, for example, that there is a large-scale trend in evolution ...
We consider a simple stochastic differential equation for modeling bubbles in social context. A prime example is bubbles in asset pricing, but similar mechanisms may control a range of social phenomen...
Aerosol optical depth retrieval over land surface using remote sensing employs the use of radiative transfer simulations and/or simultaneous measurements of atmospheric parameters at the time of satel...
This paper argues that conflicting results from previous literature—related to the effect of economic conditions on child labor—derive from different income and substitution effects implicit in differ...
Advances in High-Performance Computing (HPC) offer Computational Social Science the opportunity to create simulations at scales vastly larger than in previous times. Here an example is presented showi...
A novel and simple model is proposed for the measurement of the linewidth enhancement factor (LEF) α of multiwavelengths semiconductor laser. It is based on the suppression characteristics of an arbit...
Nonlinear dynamics of a bouncing ball moving in gravitational field and colliding with a moving limiter is considered. Displacement of the limiter is a quadratic function of time. Several dynamical mo...

Many river basins of the western U.S. were initially developed for crop irrigation, mostly after the passage of the Reclamation Act of 1906. The diversion for irrigation reduced streamflow and incre...

We propose a simple stochastic model for time series which is analytically tractable, easy to simulate and which captures some relevant stylized facts of financial indexes, including scaling properti...
The Lee Carter modelling framework is widely used because of its simplicity and robustness despite its inability to model specific cohort effects. A large number of extensions have been proposed that ...

Gas hydrates have been of interest for years, but as of late they have become increasingly considered as a potential energy source, a potential environmental impact, and a geohazard. This paper discus...
We have studied a hybrid model combining the forest-fire model with the site-percolation model in order to better understand the earthquake cycle. We consider a square array of sites. At each time ste...
