Topological Interpretation of Barbero-Immirzi Parameter

open access: yes, 2008
We set up a canonical Hamiltonian formulation for a theory of gravity based on a Lagrangian density made up of the Hilbert-Palatini term and, instead of the Holst term, the Nieh-Yan topological density.

Linear Gaussian Affine Term Structure Models with Unobservable Factors: Calibration and Yield Forecasting [PDF]

open access: yes, 2008
This paper provides a significant numerical evidence for out-of-sample forecasting ability of linear Gaussian interest rate models with unobservable underlying factors. We calibrate one, two and three factor linear Gaussian models using the Kalman filter

The Vertex-Face Correspondence and Correlation Functions of the Fusion Eight-Vertex Model I: The General Formalism

open access: yes, 2005
Based on the vertex-face correspondence, we give an algebraic analysis formulation of correlation functions of the $k\times k$ fusion eight-vertex model in terms of the corresponding fusion SOS model. Here $k\in Z_{>0}$. A general formula for correlation

On signalling over through-silicon via (TSV) interconnects in 3-D integrated circuits. [PDF]

open access: yes, 2010
This paper discusses signal integrity (SI) issues and signalling techniques for Through Silicon Via (TSV) interconnects in 3-D Integrated Circuits (ICs). Field-solver extracted parasitics of TSVs have been employed in Spice simulations to investigate the

An effective AMS Top-Down Methodology Applied to the Design of a Mixed-SignalUWB System-on-Chip [PDF]

open access: yes, 2007
The design of Ultra Wideband (UWB) mixed-signal SoC for localization applications in wireless personal area networks is currently investigated by several researchers. The complexity of the design claims for effective top-down methodologies.

On the equivalence of the discrete nonlinear Schr\"odinger equation and the discrete isotropic Heisenberg magnet

open access: yes, 1999
The equivalence of the discrete isotropic Heisenberg magnet (IHM) model and the discrete nonlinear Schr\"odinger equation (NLSE) given by Ablowitz and Ladik is shown.

Asymptotic analysis and spectrum of three anyons

open access: yes, 1993
The spectrum of anyons confined in harmonic oscillator potential shows both linear and nonlinear dependence on the statistical parameter. While the existence of exact linear solutions have been shown analytically, the nonlinear dependence has been ...

Refrigeration for preservation of the Moroccan date: Situation and physical analysis of the quality

open access: yesRevue Marocaine des Sciences Agronomiques et Vétérinaires, 2018
The production of date palm in Morocco, estimated at around one hundred thousand tons per year, contributes to the generation of income, 40 to 60%, for nearly 2 million of the oasis population. However, this date palm production is exposed to constraints
