Evolution of macrolide resistance in streptococcus pyogenes over 14 years in an area of central Italy [PDF]
, 2015 We evaluated temporal fluctuations in macrolide resistance rates, analysing genetic determinants of resistance and clonal evolution in a population of 2744 S. pyogenes isolates collected in the period 2000–2013.

Tensor-based numerical method for stochastic homogenisation
, 2018 This paper addresses the complexity reduction of stochastic homogenisation of a class of random materials for a stationary diffusion equation. A cost-efficient approximation of the correctors is built using a method designed to exploit quasi-periodicity.

KAM for the quantum harmonic oscillator
, 2011 In this paper we prove an abstract KAM theorem for infinite dimensional Hamiltonians systems. This result extends previous works of S.B. Kuksin and J. P\"oschel and uses recent techniques of H. Eliasson and S.B. Kuksin.

Trigonal curves and algebro-geometric solutions to soliton hierarchies
, 2016 Using linear combinations of Lax matrices of soliton hierarchies, we introduce trigonal curves by their characteristic equations, and determine Dubrovin type equations for zeros and poles of meromorphic functions defined as ratios of the Baker-Akhiezer ...

Almost periodic pseudodifferential operators and Gevrey classes
, 2011 We study almost periodic pseudodifferential operators acting on almost periodic functions $G_{\rm ap}^s(\rr d)$ of Gevrey regularity index $s \geq 1$. We prove that almost periodic operators with symbols of H\"ormander type $S_{\rho,\delta}^m$ satisfying

Asymptotic periodic solutions of differential equations with infinite delay
, 2023 In this paper, by using the spectral theory of functions and properties of evolution semigroups, we establish conditions on the existence, and uniqueness of asymptotic 1-periodic solutions to a class of abstract differential equations with infinite delay

, 2013 The paper is to study the asymptotic dynamics in nonmonotone comparable almost periodic reaction-diffusion system with Dirichlet boundary condition, which is comparable with uniformly stable strongly order-preserving system. By appealing to the theory of

Soliton interaction with small Toeplitz potentials for the Szego equation on the real line
, 2011 We consider the cubic Szego equation perturbed by a small Toeplitz potential (natural generalization of a multiplicative potential) and having as initial condition a soliton of the unperturbed equation.

Almost automorphic solutions for Lotka-Volterra systems with diffusion and time-dependent parameters [PDF]
In this work we study the response for a class of Lotka-Volterra prey- predator systems with diffusion and time-dependent parameters to a large class of oscillatory type functions, namely the pseudo almost automorphic type oscillations.
