Self-association in multilayer linear networks with limited connectivity.

Neural networks : the official journal of the International Neural Network Society

Palmieri F, Corvino M.
PMID: 12662799
Neural Netw. 1998 Jun;11(4):601-609. doi: 10.1016/s0893-6080(98)00037-9.

We study the behavior of linear neural networks having constrained connectivity of Hebbian and anti-Hebbian synapses. We derive some general results for cascade architectures and a formula for the number of layers necessary to obtain a sufficiently close approximation...

Discrete Green's methods and their application to two-dimensional phase unwrapping.

Journal of the Optical Society of America. A, Optics, image science, and vision

Marano S, Palmieri F, Franceschetti G.
PMID: 12095199
J Opt Soc Am A Opt Image Sci Vis. 2002 Jul;19(7):1319-33. doi: 10.1364/josaa.19.001319.

A fully self-contained discrete framework with discrete equivalents of Stokes's, Gauss's, and Green's theorems is presented. The formulation is analogous to that of continuous operators, but totally discrete in nature, and the exact relationships derived are shown to hold...

Phase transitions in electrorheological fluids using molecular dynamics simulations.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Lapenta G, Maizza G, Palmieri A, Boretto G, Debenedetti M.
PMID: 11970306
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 1999 Oct;60(4):4505-10. doi: 10.1103/physreve.60.4505.

A parametric study of the properties of electrorheological fluids is conducted using molecular dynamics (MD) simulations. The MD model is based on the solution of the Langevin equation for a number of suspended particles. The equations of motion include...

Simplified phenomenological model for randomly birefringent strongly spun fibers.

Optics letters

Galtarossa A, Palmieri L, Schenato L.
PMID: 16832457
Opt Lett. 2006 Aug 01;31(15):2275-7. doi: 10.1364/ol.31.002275.

A simplified phenomenological model for the description of randomly birefringent, strongly spun fibers is proposed. It is shown that the spinning, besides causing an apparent reduction of the linear random birefringence, may also induce an apparent deterministic circular birefringence.

Statistical characterization of fiber random birefringence.

Optics letters

Galtarossa A, Palmieri L, Schiano M, Tambosso T.
PMID: 18066204
Opt Lett. 2000 Sep 15;25(18):1322-4. doi: 10.1364/ol.25.001322.

The statistical properties of the random birefringence that affects long single-mode fibers are experimentally evaluated by means of a polarization-sensitive optical time-domain reflectometry. The measurements are in good agreement with theoretical predictions and show, for what we believe is...

Calculation of the mean differential group delay of periodically spun, randomly birefringent fibers.

Optics letters

Galtarossa A, Griggio P, Pizzinat A, Palmieri L.
PMID: 18007901
Opt Lett. 2002 May 01;27(9):692-4. doi: 10.1364/ol.27.000692.

Spinning is one of the most effective and well-known ways to reduce polarization mode dispersion of optical fibers. In spite of the popularity of spinning, a detailed theory of spin effects is still lacking. We report an analytical expression...

A functional fatiguing protocol and deceleration time of the shoulder from an internal rotation perturbation.

Journal of athletic training

Bowman TG, Hart JM, McGuire BA, Palmieri RM, Ingersoll CD.
PMID: 17043695
J Athl Train. 2006 Jul-Sep;41(3):275-9.

CONTEXT: Muscular fatigue impedes sensorimotor function and may increase the risk of shoulder injury during activity. The effects of fatigue on the sensorimotor system of the shoulder have been studied with various results. Deceleration times have been used to...

Measurements of beat length and perturbation length in long single-mode fibers.

Optics letters

Galtarossa A, Palmieri L, Schiano M, Tambosso T.
PMID: 18059887
Opt Lett. 2000 Mar 15;25(6):384-6. doi: 10.1364/ol.25.000384.

Experimental results of measurement of the beat length and the differential group delay of several types of long single-mode fiber are presented. The proposed measurement technique is based on a polarization-sensitive analysis of the backscattered signal and allows one...

Extracting single and two-exciton couplings in photosynthetic complexes by coherent two-dimensional electronic spectra.

Chemical physics

Abramavicius D, Palmieri B, Mukamel S.
PMID: 20617102
Chem Phys. 2008 Aug 22;357(1):79-84. doi: 10.1016/j.chemphys.2008.10.010.

Signatures of "strong" J and "weak" K exciton couplings in the nonlinear femtosecond optical response of the FMO photosynthetic complex are identified. The two types of couplings originate from interactions of molecular transition charge dipoles and change of molecular...

Acoustooptic interaction for most effective deflection of unguided light via acoustic surface waves.

The light deflection efficiencies of surface acoustic waves propagating on YZ-LiNbO(3) crystal are examined for different geometrical configurations. The optimum one is found to be the back reflection geometry, with S polarization of the impinging light beam, where a...
