Adsorption thermodynamics of two-domain antifreeze proteins: theory and Monte Carlo simulations.

Physical chemistry chemical physics : PCCP

Narambuena CF, Sanchez Varretti FO, Ramirez-Pastor AJ.
PMID: 27539563
Phys Chem Chem Phys. 2016 Sep 21;18(35):24549-59. doi: 10.1039/c6cp03924c. Epub 2016 Aug 19.

In this paper we develop the statistical thermodynamics of two-domain antifreeze proteins adsorbed on ice. We use a coarse-grained model and a lattice network in order to represent the protein and ice, respectively. The theory is obtained by combining...

Mott physics beyond Brinkman-Rice scenario.

Physical review. B

Wysokiński MM, Fabrizio M.
PMID: 28516170
Phys Rev B. 2017 Apr 15;95(16). doi: 10.1103/PhysRevB.95.161106.

The main flaw of the well-known Brinkman-Rice description, obtained through the Gutzwiller approximation, of the paramagnetic Mott transition in the Hubbard model is in neglecting high-energy virtual processes that generate for instance the antiferromagnetic exchange

Qualitatively Incorrect Features in the TDDFT Spectrum of Thiophene-Based Compounds.

The journal of physical chemistry letters

Prlj A, Curchod BF, Fabrizio A, Floryan L, Corminboeuf C.
PMID: 26263085
J Phys Chem Lett. 2015 Jan 02;6(1):13-21. doi: 10.1021/jz5022087. Epub 2014 Dec 09.

Ab initio molecular electronic structure computations of thiophene-based compounds constitute an active field of research prompted by the growing interest in low-cost materials for organic electronic devices. In particular, the modeling of electronically excited states and other time-dependent phenomena...

Methods of Evaluation of Anorectal Causes of Obstructed Defecation.

Clinics in colon and rectal surgery

Fabrizio AC, Alimi Y, Kumar AS.
PMID: 28144212
Clin Colon Rectal Surg. 2017 Feb;30(1):46-56. doi: 10.1055/s-0036-1593427.

Obstructed defecation is a complex disorder that results in impaired propagation of stool from the rectum. It is one of the major subtypes of functional constipation and can be secondary to either functional or anatomic etiologies. Patients with obstructed...

Influence of Cu, TiO2 Nanoparticles and Carbon Nano-Horns on Tribological Properties of Engine Oil.

Journal of nanoscience and nanotechnology

Zin V, Agresti F, Barison S, Colla L, Fabrizio M.
PMID: 26504981
J Nanosci Nanotechnol. 2015 May;15(5):3590-8. doi: 10.1166/jnn.2015.9839.

The addition of nanoparticles in lubricating oils recently demonstrated to reduce the coefficient of friction and to increase the load-carrying capability of lubricant in coupled surfaces. In this work, different kinds of nanoparticles were tested as additives to engine...

TU-E-217BCD-11: Evaluating the Performance of a Stationary Digital Breast Tomosynthesis System.

Medical physics

Tucker A, Gidcumb E, Shan J, Qian X, Sprenger F, Spronk D, Zhang Y, Kennedy D, Farbizio T, Ruth C, Jing Z, Lu J, Zhou O.
PMID: 28518705
Med Phys. 2012 Jun;39(6):3916. doi: 10.1118/1.4735983.

PURPOSE: In conventional Digital Breast Tomosynthesis (DBT) systems a single x-ray source moves over a limited angle arc. This leads to motion blurring in the projection images associated with x-ray source motion and total scan times. We have developed...

Broadband Phase Spectroscopy over Turbulent Air Paths.

Physical review letters

Giorgetta FR, Rieker GB, Baumann E, Swann WC, Sinclair LC, Kofler J, Coddington I, Newbury NR.
PMID: 26382677
Phys Rev Lett. 2015 Sep 04;115(10):103901. doi: 10.1103/PhysRevLett.115.103901. Epub 2015 Sep 01.

Broadband atmospheric phase spectra are acquired with a phase-sensitive dual-frequency-comb spectrometer by implementing adaptive compensation for the strong decoherence from atmospheric turbulence. The compensation is possible due to the pistonlike behavior of turbulence across a single spatial-mode path combined...

Ni-Zr alloys: relationship between surface characteristics and electrocatalytic behavior.

Rapid communications in mass spectrometry : RCM

Angelini E, Antonione C, Baricco M, Daolio S, Fabrizio M, Rosalbino F.
PMID: 10825019
Rapid Commun Mass Spectrom. 2000;14(9):800-7. doi: 10.1002/(SICI)1097-0231(20000515)14:9<800::AID-RCM947>3.0.CO;2-F.

A relationship between electrocatalytic activity for the hydrogen evolution reaction and the surface composition of the electrode was established for Ni-Zr crystalline and amorphous alloys by means of secondary ion mass spectrometry (SIMS). Electrocatalytic activity was tested by means...

Quasiparticle conductivities in disordered d-wave superconductors.

Physical review letters

Fabrizio M, Dell'Anna L, Castellani C.
PMID: 11863927
Phys Rev Lett. 2002 Feb 18;88(7):076603. doi: 10.1103/PhysRevLett.88.076603. Epub 2002 Feb 01.

We study the quasiparticle transport coefficients in disordered d-wave superconductors. We find that spin and charge excitations are generally localized unless magnetic impurities are present. If the system is close to a nesting point in the impurity-scattering unitary limit,...

Variational description of Mott insulators.

Physical review letters

Capello M, Becca F, Fabrizio M, Sorella S, Tosatti E.
PMID: 15698205
Phys Rev Lett. 2005 Jan 21;94(2):026406. doi: 10.1103/PhysRevLett.94.026406. Epub 2005 Jan 20.

The Gutzwiller wave function for a strongly correlated model can, if supplemented with a long-range Jastrow factor, provide a proper variational description of Mott insulators, so far unavailable. We demonstrate this concept in the prototypical one-dimensional t-t(') Hubbard model,...

Previous studies have suggested that abnormal corneal wound healing in patients after photorefractive keratectomy (PRK) is associated with the appearance of myofibroblasts in the stroma between two and four weeks after surgery. The purpose of this study was to...
