Social Influence on Observed Race

open access: yesSociological Science, 2018
This article introduces a novel theoretical approach for understanding racial fluidity, emphasizing the social embeddedness of racial classifications. We propose that social ties affect racial perceptions through within-group micromechanisms, resulting ...

Methods for analysis of functionals on Gaussian self similar processes [PDF]

open access: yes, 2018
Many engineering and scientific applications necessitate the estimation of statistics of various functionals on stochastic processes. In Chapter 2, Norros et al’s Girsanov theorem for fBm is reviewed and extended to allow for non-unit volatility. We then

Macroscopic Quantum-Type Potentials in Theoretical Systems Biology

open access: yesCells, 2013
We review in this paper the use of the theory of scale relativity and fractal space-time as a tool particularly well adapted to the possible development of a future genuine systems theoretical biology.

Collective dynamics of gene expression in cell populations.

open access: yesPLoS ONE, 2011
The phenotypic state of the cell is commonly thought to be determined by the set of expressed genes. However, given the apparent complexity of genetic networks, it remains open what processes stabilize a particular phenotypic state.

Stochastic simulation of destruction processes in self-irradiated materials

open access: yesCondensed Matter Physics, 2017
Self-irradiation damages resulting from fission processes are common phenomena observed in nuclear fuel containing (NFC) materials. Numerous α-decays lead to local structure transformations in NFC materials.

Invariance properties of the negative binomial Levy process and stochastic self-similarity [PDF]

open access: yesInternational Mathematical Forum, 2007
We study the concept of self-similarity with respect to stochastic time change. The negative binomial process (NBP) is an example of a family of random time transformations with respect to which stochastic self-similarity holds for certain stochastic processes.

Coevolving edge rounding and shape of glacial erratics: the case of Shap granite, UK [PDF]

open access: yesEarth Surface Dynamics
The size distributions and the shapes of detrital rock clasts can shed light on the environmental history of the clast assemblages and the processes responsible for clast comminution.

On the cross-variation of a class of stochastic processes

open access: yesResults in Applied Mathematics
The present paper deals with the study of the cross-variation of two-dimensional stochastic process defined using the Young integral with respect to a continuous, α-self-similar Gaussian process that does not necessarily have stationary increments, with ...

Performance Evaluation of Linear (ARMA) and Threshold Nonlinear (TAR) Time Series Models in Daily River Flow Modeling (Case Study: Upstream Basin Rivers of Zarrineh Roud Dam)

open access: yesمجله آب و خاک, 2017
Introduction: Time series models are generally categorized as a data-driven method or mathematically-based method. These models are known as one of the most important tools in modeling and forecasting of hydrological processes, which are used to design ...
