Code Saturation Versus Meaning Saturation: How Many Interviews Are Enough?.

Qualitative health research

Hennink MM, Kaiser BN, Marconi VC.
PMID: 27670770
Qual Health Res. 2017 Mar;27(4):591-608. doi: 10.1177/1049732316665344. Epub 2016 Sep 26.

Saturation is a core guiding principle to determine sample sizes in qualitative research, yet little methodological research exists on parameters that influence saturation. Our study compared two approaches to assessing saturation: code saturation and meaning saturation. We examined sample...

Effective equilibrium picture in the xy model with exponentially correlated noise.

Physical review. E

Paoluzzi M, Marconi UMB, Maggi C.
PMID: 29548092
Phys Rev E. 2018 Feb;97(2):022605. doi: 10.1103/PhysRevE.97.022605.

We study the effect of exponentially correlated noise on the xy model in the limit of small correlation time, discussing the order-disorder transition in the mean field and the topological transition in two dimensions. We map the steady states...

IMPACT OF TAXONOMY, GEOGRAPHY, AND DEPTH ON δ(13) C AND δ(15) N VARIATION IN A LARGE COLLECTION OF MACROALGAE(1).

Journal of phycology

Marconi M, Giordano M, Raven JA.
PMID: 27020183
J Phycol. 2011 Oct;47(5):1023-35. doi: 10.1111/j.1529-8817.2011.01045.x. Epub 2011 Aug 29.

The natural abundance of carbon stable isotopes (δ(13) C) of marine macrophytes has been measured in previous studies and used to analyze differences in Ci assimilation among the three macroalgal phyla, Chlorophyta, Ochrophyta, and Rhodophyta, and seagrasses, distinguishing diffusive...

Screening, diagnosis and treatment of osteoporosis: a brief review.

Clinical cases in mineral and bone metabolism : the official journal of the Italian Society of Osteoporosis, Mineral Metabolism, and Skeletal Diseases

Bernabei R, Martone AM, Ortolani E, Landi F, Marzetti E.
PMID: 25568654
Clin Cases Miner Bone Metab. 2014 Sep;11(3):201-7.

Osteoporosis is a highly prevalent condition characterized by decreases in bone mass and microarchitectural alterations. Bone fractures, especially of the hip and vertebrae, are the most burdensome complications of osteoporosis, being associated with high risk of disability, institutionalization and...

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...

Detection of pleural plaques in workers exposed to inhalation of natural fluoro-edenite fibres.

Oncology letters

Rapisarda V, Ledda C, Ricceri V, Arena F, Musumeci A, Marconi A, Fago L, Bracci M, Santarelli L, Ferrante M.
PMID: 26137010
Oncol Lett. 2015 May;9(5):2046-2052. doi: 10.3892/ol.2015.2978. Epub 2015 Feb 19.

Fluoro-edenite is a natural mineral species initially isolated in Biancavilla, Sicily. The fibres are similar in size and morphology to certain amphibolic asbestos fibres, the inhalation of which may cause chronic inflammation and cancer. Occupational asbestos exposure is known...

The RR Lyrae Star U Comae as a Test for Nonlinear Pulsation Models.

The Astrophysical journal

Bono G, Castellani V, Marconi M.
PMID: 10715241
Astrophys J. 2000 Apr 01;532(2):L129-L132. doi: 10.1086/312582.

We use high-precision multiband photometric data of the first-overtone RR Lyrae star U Comae to investigate the predictive capability of full-amplitude, nonlinear, convective hydrodynamical models. The main outcome of this investigation is that theoretical predictions properly account for the...

Noise activated granular dynamics.

Physical review letters

Cecconi F, Puglisi A, Marconi UM, Vulpiani A.
PMID: 12633295
Phys Rev Lett. 2003 Feb 14;90(6):064301. doi: 10.1103/PhysRevLett.90.064301. Epub 2003 Feb 10.

We study the behavior of two particles moving in a bistable potential, colliding inelastically with each other and driven by a stochastic heat bath. The system has the tendency to clusterize, placing the particles in the same well at...

Statistical mechanics of granular gases in compartmentalized systems.

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

Marconi UM, Puglisi A.
PMID: 14524762
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Sep;68(3):031306. doi: 10.1103/PhysRevE.68.031306. Epub 2003 Sep 22.

We study the behavior of an assembly of N granular particles contained in two compartments within a simple kinetic approach. The particles belonging to each compartment collide inelastically with each other and are driven by a stochastic heat bath....

Observation of a multiply ionized plasma with index of refraction greater than one.

Physical review letters

Filevich J, Rocca JJ, Marconi MC, Moon SJ, Nilsen J, Scofield JH, Dunn J, Smith RF, Keenan R, Hunter JR, Shlyaptsev VN.
PMID: 15698278
Phys Rev Lett. 2005 Jan 28;94(3):035005. doi: 10.1103/PhysRevLett.94.035005. Epub 2005 Jan 27.

We present clear experimental evidence showing that the contribution of bound electrons can dominate the index of refraction of laser-created plasmas at soft x-ray wavelengths. We report anomalous fringe shifts in soft x-ray laser interferograms of Al laser-created plasmas....

Guiding of intense laser beams in highly ionized plasma columns generated by a fast capillary discharge.

We have demonstrated the guiding of laser pulses with peak intensities up to 2.2 x 10(17) W/cm(2) in a 5.5 cm long plasma column containing highly charged Ar ions generated by a fast capillary discharge. A rapid discharge-driven hydrodynamic...
