Variational and stability properties of constant Solutions to the NLS equation on compact metric graphs

We consider the nonlinear Schrödinger equation with pure power nonlinearity on a general compact metric graph, and in particular its stationary solutions with fixed mass. Since the the graph is compact, for every value of the mass there is a constant solution. Our scope is...

Lower bounds for the first eigenvalue of the Laplacian with zero magnetic field in planar domains

We study the Laplacian with zero magnetic field acting on complex functions of a planar domain Ω, with magnetic Neumann boundary conditions. If Ω is simply connected then the spectrum reduces to the spectrum of the usual Neumann Laplacian; therefore we focus on multiply connec...

Fractional (s, p)-Robin–Venttsel’ problems on extension domains

We study a nonlocal Robin–Venttsel’-type problem for the regional fractional p-Laplacian in an extension domain Ω with boundary a d-set. We prove existence and uniqueness of a strong solution via a semigroup approach. Markovianity and ultracontractivity properties are proved. We then conside...

A fast preprocessing method for micro-expression spotting via perceptual detection of frozen frames

This paper presents a preliminary study concerning a fast preprocessing method for facial microexpression (ME) spotting in video sequences. The rationale is to detect frames containing frozen expressions as a quick warning for the presence of MEs. In fact, those frames can either p...

Stable oxygen and carbon isotope composition of holocene mytilidae from the camarones coast (Chubut, argentina). Palaeoceanographic implications

The stable isotope composition of living and of Holocene Mytilidae shells was measured in the area of Camarones (Chubut, Argentina). The most striking results were the high δ18 O values measured in samples older than ca. 6.1 cal ka BP. In the younger samples, the δ18 ...
