We prove that the superlinear indefinite equation u"+a(t)up=0, where p>1 and a(t) is a T-periodic sign-changing function satisfying the (sharp) mean value condition ∫a(t) dt<0, has positive subharmonic solutions of order ...
We study the periodic boundary value problem associated with the second order nonlinear equation u''+(λa+(t)−μa−(t))g(u)=0, where g(u) has superlinear growth at zero and sublinear growth at infinity. For λ,μ positive and ...
We present a fixed point theorem on topological cylinders in normed linear spaces for maps satisfying a property of stretching a space along paths. This result is a generalization of a similar theorem obtained by D. Papini ...

We study the periodic and Neumann boundary value problems associated with the second order nonlinear differential equation u''+cu'+λa(t)g(u)=0, where g:[0,+∞[→[0,+∞[ is a sublinear function at infinity having superlinear ...
We deal with the existence of positive solutions for a two-point boundary value problem associated with the nonlinear second order equation u''+a(x)g(u)=0. The weight a(x) is allowed to change sign. We assume that the ...
The aim of this paper is to study the quasistatic limit of a one-dimensional model of
dynamic debonding. We start from a dynamic problem that strongly couples the wave equation in a time-dependent domain with Griffith's ...
Neurons are highly polarised cells that migrate elongating their axon to reach distant synaptic targets. In the developing nervous system they travel along highly conserved trajectories defined by the molecules present in ...
Recently, an innovative protocol of electrical stimulation, named “fictive locomotion induced stimulation” (FListim), which consists of an intrinsically variable noisy waveform, has been obtained from a segment of ...
The present thesis is devoted to the study of physical phenomena emerging from
strong correlations in strongly interacting quantum many-body systems with several
components. Hubbard models are widely used as minimal ...
BACKGROUND: Prion diseases, such as bovine spongiform encephalopathies (BSE), are transmissible neurodegenerative disorders affecting humans and a wide variety of mammals. Variant Creutzfeldt-Jakob disease (vCJD), a prion ...
Auditory speech perception can be described as the task of mapping an auditory
signal into meaning. We routinely perform this task in an automatic and effortless
manner, which might conceal the complexity behind this ...
This thesis studies learning mechanisms and cognitive biases present from birth involved in language acquisition, in particular in speech segmentation and the extraction of linguistic regularities. Due to the sequential ...
PARSEC (PAdova-TRieste Stellar Evolution Code) is the updated version of the the stellar evolution code used in Padova. It provides stellar tracks and isochrones for stellar mass from 0.1 M ⊙ to 350 M ⊙ and metallicity ...
The experimental evidences of neutrino oscillation, caused by non-zero neutrino masses and neutrino mixing, which were obtained in the experiments with solar, atmospheric, accelerator and reactor neutrinos, opened new field ...
Most bioinformatic analyses start by building sequence alignments by means of scoring matrices. An implicit approximation on which many scoring matrices are built is that protein sequence evolution is considered a sequence ...
The computational study of conformational transitions in nucleic acids still faces many challenges. For example, in the case of single stranded RNA tetranucleotides, agreement between simulations and experiments is not ...
We study screw dislocations in an isotropic crystal undergoing antiplane shear.
In the framework of linear elasticity, by fixing a suitable boundary condition for the strain
(prescribed non-vanishing boundary integral), ...
We study a two-dimensional rotating Bose-Einstein condensate confined by an anharmonic trap in the framework of the Gross-Pitaevskii theory. We consider a rapid rotation regime close to the transition to a giant vortex ...
