Quantum tunneling fragmentation model
(2000-12-01)
A nonthermal quantum mechanical statistical fragmentation model based on tunneling of particles through potential barriers is studied in compact two- and three-dimensional systems. It is shown that this fragmentation ...

Species–fragmented area relationship
(Proceedings of the National Academy of Sciences (PNAS), 2013-07-30)
The species–area relationship (SAR) gives a quantitative description of the increasing number of species in a community with increasing area of habitat. In conservation, SARs have been used to predict the number of extinctions ...
Model for Optimization of Drilling, Blasting and Fragmentation Processes in medium mining
(International Institute of Informatics and Systemics, IIIS, 2019-01-01)
This study aims to propose a new alternative to optimize drilling and blasting processes from the mathematical and geological viewpoint using simulation software. The main objective is to design a systematic model of steps ...
Fragmentation drives tropical forest fragments to early successional states: A modelling study for Brazilian Atlantic forests
(ELSEVIER SCIENCE BV, 2011)
Land use leads to massive habitat destruction and fragmentation in tropical forests. Despite its global dimensions the effects of fragmentation on ecosystem dynamics are not well understood due to the complexity of the ...
Mechanisms affecting population density in fragmented habitat
(RESILIENCE ALLIANCE, 2005)
We conducted a factorial simulation experiment to analyze the relative importance of movement pattern, boundary-crossing probability, and mortality in habitat and matrix on population density, and its dependency on habitat ...
Water worlds in N-body simulations with fragmentation in systems without gaseous giants
(EDP Sciences, 2020-08)
We analyze the formation and evolution of terrestrial-like planets around solar-type stars in the absence of gaseous giants. In particular, we focus on the physical and dynamical properties of those that survive in the ...
Water fragmentation induced by ion impact: Fragment-ion-energy determination at different ZP/v regimes
(Elsevier, 2017-10-01)
This work focuses on the energy distributions of positive water ionic fragments produced by ion impact at MeV impact energies. An improved Coulomb explosion model coupled to a classical trajectory Monte Carlo simulation ...
Physical properties of terrestrial planets and water delivery in the habitable zone using N-body simulations with fragmentation
(EDP Sciences, 2019-11-13)
The goal of this research is to study how the fragmentation of planetary embryos can affect the physical and dynamical properties of terrestrial planets around solar-type stars. Our work focuses on the formation and evolution ...
