Thermal Tensor Renormalization Group Simulations of Square-Lattice Quantum Spin Models

open access: yes, 2019
In this work, we benchmark the well-controlled and numerically accurate exponential thermal tensor renormalization group (XTRG) in the simulation of interacting spin models in two dimensions.

Arboreal frogs, tank bromeliads and disturbed seasonal tropical forest [PDF]

open access: yes, 2003
We investigated the relationship between arboreal frogs, tank bromeliads and landscape transformation in tropical forests of southeastern Campeche, Mexico. We surveyed frogs in six distinct habitats: slash and burn agriculture, seasonally flooded forest (

Probing the light induced dipole-dipole interaction in momentum space

open access: yes, 2005
We theoretically investigate the mechanical effect of the light-induced dipole-dipole interaction potential on the atoms in a Bose-Einstein condensate. We present numerical calculations on the magnitude and shape of the induced potentials for different ...

Modeling financial time series with the skew slash distribution [PDF]

open access: yes, 2012
Financial returns often present moderate skewness and high kurtosis. As a consequence, it is natural to look for a model that is exible enough to capture these characteristics.

AN EXTENSION OF THE TWO-PARAMETER WEIBULL DISTRIBUTION UNA EXTENSIÓN DE LA DISTRIBUCIÓN WEIBULL DE DOS PARÁMETROS

open access: yesRevista Colombiana de Estadística, 2010
In this paper, we present an extension of the Two-parameter Weibull distribution to make it even more flexible in terms of its kurtosis coefficient. Properties involving moments and asymmetry and kurtosis indexes are studied.

The start of sustainability in Amazonia? A new paradigm based on fertility for sustainable land management [PDF]

open access: yes, 2008
In the Amazon, slash and burn is the most common technique used by American-Indians, small farmers and even big ranches to transform forests into rural landscapes.

How tightly linked are Pericopsis elata (Fabaceae) patches to anthropogenic disturbances in Southeastern Cameroon? [PDF]

open access: yes, 2015
While most past studies have emphasized the relationships between specific forest stands and edaphic factors, recent observations in Central African moist forests suggested that an increase of slash-and-burn agriculture since 3000–2000 BP (Before Present)
