Modeling Social Networks with Node Attributes using the Multiplicative Attribute Graph Model
Modeling Social Networks Node Multiplicative Attribute Graph Model
2011/9/15
Networks arising from social, technological and natural domains exhibit rich connectivity patterns and nodes in such networks are often labeled with attributes or features. We address the question of ...
Phase transition in the Sznajd model with independence
Social systems Spin chain models Scaling phenomena in complex systems
2011/8/29
We propose a model of opinion dynamics which describes two major types of social influence - conformity and independence. Conformity in our model is described by the so called outflow dynamics (known ...
Effective spin model for interband transport in a Wannier-Stark lattice system
Effective spin model interband transport Wannier-Stark lattice system
2010/10/29
We show that the interband dynamics in a tilted two-band Bose-Hubbard model can be reduced to an analytically accessible spin model in the case of resonant interband oscillations. This allows us to pr...
Achieving the physical limits of the bounded-storage model
physical limits bounded-storage model
2010/10/19
Secure two-party cryptography is possible if the adversary’s quantum storage device suffers imperfections.For example, security can be achieved if the adversary can store strictly less then half of th...
The Triple Helix Model and the Meta-Stabilization of Urban Technologies in Smart Cities
Triple Helix Model Urban Technologies Meta-Stabilization
2010/4/6
The Triple Helix model of university-industry-government relations can be generalized from a neo-institutional model of networks to a neo-evolutionary model of how three selection environments operate...
Collapse and revival in inter-band oscillations of a two-band Bose-Hubbard model
inter-band oscillations two-band Bose-Hubbard model
2010/3/10
We study the effect of a many-body interaction on inter-band oscillations in a two-band Bose-Hubbard model with external Stark force. Weak and strong inter-band oscillations are observed, where the la...
Predictability of extreme events in a branching diffusion model
extreme events branching diffusion model
2010/4/6
We propose a framework for studying predictability of extreme events in complex systems. Major conceptual elements -- hierarchical structure, spatial dynamics, and external driving -- are combined in ...
Inclusive Search for Standard Model Higgs Boson Production in the WW Decay Channel using the CDF II Detector
standard model Model Higgs Boson
2010/3/15
We present a search for standard model (SM) Higgs boson production using ppbar collision data at sqrt(s) = 1.96 TeV, collected with the CDF II detector and corresponding to an integrated luminosity of...
It is known that Heston's stochastic volatility model exhibits moment explosion, and that the critical moment $s^{*}$ can be obtained by solving (numerically) a simple equation. This yields a leading ...
Phenomenological Model for the metal-insulator transition in two dimensions
metal-insulator transition logistics equation
2010/7/8
The resistivity measured in two-dimensional MOSFET geometry is modeled by considering that the resistivity is a function of the temperature and the areal density of charges (electrons or holes). The l...
Critical behavior of the delay-induced chaos transition in a nonlinear model for the immune
Delayed systems Immune response Chaos
2010/7/5
In this paper we analyze a model for the dynamics of the immune system interacting with a target population.The model consists in a set of two-dimensional delayed differential equations. The model is ...
We study the adiabatic evolution of a two-level model in the presence of an external classical electric field. The coupling between the quantum model and the classical field is taken in the electric d...
Box Model for Hysteresis Loops of Arrays of Ni Nanowires
Nanowires Hysteresis Phenomenological model
2010/9/25
In the present work, by means of a phenomenological model, we simulate the hysteresis loop of an hexagonal array of Ni nanowires. Our model is based on the assumption that the hysteresis loop of a sin...
A Model for a Non-Minimally Coupled Scalar Field Interacting with Dark Matter
a Non-Minimally Coupled Scalar Field Dark Matter
2010/10/15
In this work we investigate the evolution of a Universe consisted of a scalar field, a dark matter field and noninteracting baryonic matter and radiation. The scalar field, which plays the role of dar...
