Shiga toxin (Stx)-producing Escherichia coli (STEC) are pathogenic E. coli causing diarrhea, hemorrhagic colitis (HC) and hemolytic uremic syndrome (HUS). STEC are characterized by a constellation of virulence factors additional to Stx and have long

Dynamical fluctuations in an exactly solvable model of spin glasses

Autor: Matteo Campellone, Paola Ranieri, Giorgio Parisi

Publikováno v: Journal of Physics A: Mathematical and General. 31:1893-1900

In this work we calculate the dynamical fluctuations at O(1/N) in the low temperature phase of the $p=2$ spherical spin glass model. We study the large-times asymptotic regimes and we find, in a short time-differences regime, a fluctuation dissipatio

Mean field dynamical exponents in finite-dimensional Ising spin glass

Autor: Federico Ricci-Tersenghi, Juan J. Ruiz-Lorenzo, Giorgio Parisi, Paola Ranieri

Publikováno v: Journal of Physics A: Mathematical and General. 30:7115-7131

We report the value of the dynamical critical exponent z for the six dimensional Ising spin glass, measured in three different ways: from the behavior of the energy and the susceptibility with the Monte Carlo time and by studying the overlap-overlap

Fluctuations in a spin-glass model with one replica symmetry breaking

Autor: Paola Ranieri, G. Parisi, M. E. Ferrero

Publikováno v: Journal of Physics A: Mathematical and General. 29:L569-L574

We discuss Gaussian fluctuations in a spin-glass model with one replica symmetry breaking (RSB) and we show how non-perturbative fluctuations of the break-point parameter can be included in the longitudinal propagator within linear response theory.

Whole genome sequence comparison of vtx2-converting phages from Enteroaggregative Haemorrhagic Escherichia coli strains

Autor: Alfredo Caprioli, Stefano Morabito, Antonella Maugliani, Valeria Michelacci, Laura Grande, Rosangela Tozzoli, Paola Ranieri

Publikováno v: BMC Genomics

Background Enteroaggregative Haemorrhagic E. coli (EAHEC) is a new pathogenic group of E. coli characterized by the presence of a vtx2-phage integrated in the genomic backbone of Enteroaggregative E. coli (EAggEC). So far, four distinct EAHEC serotyp

Dynamic fluctuations in a Short-Range Spin Glass model

Autor: Paola Ranieri

We study the dynamic fluctuations of the soft-spin version of the Edwards-Anderson model in the critical region for $T\rightarrow T_{c}^{+}$. First we solve the infinite-range limit of the model using the random matrix method. We define the static an
