Radiographic evaluation of the hip rotation centre after total joint replacement in hip dysplasia.

Hip international : the journal of clinical and experimental research on hip pathology and therapy

DAngelo F, Molina M, Giudici M, Cherubino P.
PMID: 28224574
Hip Int. 2005 Apr - Jun;15(2):92-97. doi: 10.5301/HIP.2008.5389.

A retrospective study was conducted to correlate the clinical result of joint replacement in dysplastic hips with the obtained modifications of the rotation centre. Sixty primary total hip arthroplasties were performed on 46 patients suffering from hip dysplasia at...

How lasing localized structures evolve out of passive mode locking.

Physical review letters

Marconi M, Javaloyes J, Balle S, Giudici M.
PMID: 24949767
Phys Rev Lett. 2014 Jun 06;112(22):223901. doi: 10.1103/PhysRevLett.112.223901. Epub 2014 Jun 03.

We investigate the relationship between passive mode locking and the formation of time-localized structures in the output intensity of a laser. We show how the mode-locked pulses transform into lasing localized structures, allowing for individual addressing and arbitrary low...

Perianal Crohn's disease and hidradenitis suppurativa: a possible common immunological scenario.

Clinical and molecular allergy : CMA

Giudici F, Maggi L, Santi R, Cosmi L, Annunziato F, Nesi G, Barra G, Bassotti G, De Palma R, Tonelli F.
PMID: 26203298
Clin Mol Allergy. 2015 Jul 22;13(1):12. doi: 10.1186/s12948-015-0018-8. eCollection 2015.

BACKGROUND: Crohn's disease (CD) and Hidradenitis suppurativa (HS) are both chronic inflammatory diseases. The pathogenesis of these diseases is multifactorial, due to the interaction of genetic and environmental factors leading to a deregulated local immune response where T lymphocytes...

Onset of chaos in a single-phase power electronic inverter.

Chaos (Woodbury, N.Y.)

Avrutin V, Mosekilde E, Zhusubaliyev ZT, Gardini L.
PMID: 25933662
Chaos. 2015 Apr;25(4):043114. doi: 10.1063/1.4918299.

Supported by experiments on a power electronic DC/AC converter, this paper considers an unusual transition from the domain of stable periodic dynamics (corresponding to the desired mode of operation) to chaotic dynamics. The behavior of the converter is studied...

Experimental evidence of stochastic resonance in an excitable optical system.

Physical review letters

Marino F, Giudici M, Barland S, Balle S.
PMID: 11801100
Phys Rev Lett. 2002 Jan 28;88(4):040601. doi: 10.1103/PhysRevLett.88.040601. Epub 2002 Jan 10.

Experimental evidence of stochastic resonance in an excitable optical system is reported. We apply a sinusoidal forcing to the system and, for a finite external noise level, we find a frequency for which the excitable pulsing occurs periodically at...

Cavity soliton laser based on mutually coupled semiconductor microresonators.

Physical review letters

Genevet P, Barland S, Giudici M, Tredicce JR.
PMID: 18851375
Phys Rev Lett. 2008 Sep 19;101(12):123905. doi: 10.1103/PhysRevLett.101.123905. Epub 2008 Sep 18.

We report on experimental observation of localized structures in two mutually coupled broad-area semiconductor resonators, one of which acts as a saturable absorber. These structures coexist with a dark homogeneous background and they have the same properties as cavity...

Spectroscopic on-line monitoring of reactions in dispersed medium: chemometric challenges.

Analytica chimica acta

Reis MM, Araújo PH, Sayer C, Giudici R.
PMID: 17606008
Anal Chim Acta. 2007 Jul 09;595(1):257-65. doi: 10.1016/j.aca.2007.04.048. Epub 2007 Apr 29.

Emulsion and suspension polymerizations are important industrial processes for polymer production. The end-user properties of polymers depend strongly on how the polymerization reactions proceed in time (i.e. a batch or semicontinuous, rate of reagents feeding, etc.). In other words,...

Intrinsic gap and exciton condensation in the nu{T}=1 bilayer system.

Physical review letters

Giudici P, Muraki K, Kumada N, Fujisawa T.
PMID: 20366783
Phys Rev Lett. 2010 Feb 05;104(5):056802. doi: 10.1103/PhysRevLett.104.056802. Epub 2010 Feb 02.

We investigate the quasiparticle excitation of the bilayer quantum Hall (QH) system at a total filling factor nu{T}=1 in the limit of negligible interlayer tunneling under a tilted magnetic field. We show that the intrinsic quasiparticle excitation is of...

Border collision bifurcations in a two-dimensional piecewise smooth map from a simple switching circuit.

Chaos (Woodbury, N.Y.)

Gardini L, Fournier-Prunaret D, Chargé P.
PMID: 21721748
Chaos. 2011 Jun;21(2):023106. doi: 10.1063/1.3555834.

In recent years, the study of chaotic and complex phenomena in electronic circuits has been widely developed due to the increasing number of applications. In these studies, associated with the use of chaotic sequences, chaos is required to be...

Multiplicative noise in the longitudinal mode dynamics of a bulk semiconductor laser.

Physical review. E, Statistical, nonlinear, and soft matter physics

Pedaci F, Lepri S, Balle S, Giacomelli G, Giudici M, Tredicce JR.
PMID: 16711781
Phys Rev E Stat Nonlin Soft Matter Phys. 2006 Apr;73(4):041101. doi: 10.1103/PhysRevE.73.041101. Epub 2006 Apr 17.

We analyze theoretically and experimentally the influence of current noise on the longitudinal mode hopping dynamics of a bulk semiconductor laser. It is shown that the mean residence times on each mode have different sensitivity to external noise added...

Nonvolatile polarization control of a bistable VCSEL.

Optics express

Marconi M, Barland S, Giudici M.
PMID: 23262865
Opt Express. 2012 Dec 10;20(26):B299-305. doi: 10.1364/OE.20.00B299.

We report experimental evidence of nonvolatile all-optical memory operation using the two linear polarization states emitted from a GaAs oxide-confined VCSEL. The two polarization states coexist in a large range of pumping currents and substrate temperatures, and they can...
