On a continuous mixed strategies model for Evolutionary game theory

We consider an integro-differential model for evolutionary gametheory which describes the evolution of a population adopting mixed strategies.Using a reformulation based on the first moments of the solution, we provesome analytical properties of the model and global estimates. The…

Combining network modeling and gene expression microarray analysis to explore the dynamics of Th1 and Th2 cell regulation

Two T helper (Th) cell subsets, namely Th1 and Th2 cells, play an important role in inflammatory diseases. The two subsets are thought to counter-regulate each other, and alterations in their balance result in different diseases. This paradigm has been challenged by recent clinical and experimental…

A Lattice Boltzmann model for anisotropic crystal growth from melt,

Rheology of active emulsions with negative effective viscosity

We numerically study by lattice Boltzmann simulations the rheological properties of an active emulsion made of a suspension of an active polar gel embedded in an isotropic passive background. We find that the hexatic equilibrium configuration of polar droplets is highly sensitive to both active…

The lattice Boltzmann method and multiscale hemodynamics: recent advances and perspectives

Large-scale simulations of blood flow allow for the optimal evaluation of endothelial shear stress for real-life case studies in cardiovascular pathologies. The procedure for anatomic data acquisition, geometry and mesh generation are particularly favorable if used in conjunction with the Lattice…

A review of techniques for the estimation of the term structure

An On-line Algorithm for the Rectangle Packing Problem with Rejection

In this paper an on-line algorithm for the Rectangle Packing Problem is presented. The method is designed to be able to accept or reject incoming boxes to maximize efficiency. We provide a wide computational analysis showing the behavior of the proposed algorithm as well as a comparison with…

Einstein, Planck and Vera Rubin: Relevant Encounters Between the Cosmological and the Quantum Worlds

In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of? that, even after 40 years from the Vera Rubin seminal discovery [1] does not have a proper answer. Actually, the more we…

Clathrate structure-type recognition: Application to hydrate nucleation and crystallisation

For clathrate-hydrate polymorphic structure-type (sI versus sII), geometric recognition criteria have been developed and validated. These are applied to the study of the rich interplay and development of both sI and sII motifs in a variety of hydrate-nucleation events for methane and H2S hydrate…

Wavelet Shrinkage Approaches to Baseline Signal Estimation from Repeated Noisy Measurements

We consider the problem of estimating the baseline signal from repeated noisy measurements taken on some object or individual of interest whose response is not fixed. We devise some wavelet shrinkage schemes to efficiently address the baseline signal estimation problem, adapting some well-known…
