Second Harmonic Emission From Dielectric Nanoresonators in the Absorption Regime

2023

We study second harmonic generation in dielectric nanocylinders as a function of the wavelength of the incident field and geometrical dimensions. Uncommonly, we consider a spectral range in which the emitted nonlinear signal is partially absorbed by the dielectric. Surprisingly, we reveal that the second harmonic efficiency does not decrease as the imaginary part of the complex dielectric refractive index increases. Indeed, the presence of higher order multipoles supported by the resonators at the fundamental wavelength can significantly boost the generated second harmonic signal even in the dielectric absorption spectral region achieving nonlinear efficiency of the same order of magnitude …

Becoming a Language Teacher: A dream come true or a source of anxiety?

2015

In this qualitative study the author examined personal narratives written by 14 Finnish speaking student teachers of Swedish, in order to find out what they tell about their thoughts and feelings concerning their future work as language teachers. The following three themes were in focus: firstly, what university students tell about their reasons for wanting to become teachers in the first place; secondly, what kinds of worries concerning their future work they mention in their narratives; and thirdly, how student teachers could be supported during transition from teacher education to teaching. According to the study, students choose teaching for reasons that are related to: (a) teacher iden…

Community detection of seismic point processes

2022

In this paper, we combine robin and Local Indicators of Spatio-Temporal Association (LISTA) functions. robin is an R package to assess the robustness of the community structure of a network found by one or more methods to give indications about their reliability. We use it to propose a classification algorithm of events in a spatio-temporal point pattern, by means of the local second-order characteristics and the community detection procedure in network analysis. We demonstrate the proposed procedure on a real data analysis on seismic data.

Timing an Accreting Millisecond Pulsar: Measuring the Accretion Torque in IGR J00291+5934

2006

We performed a timing analysis of the fastest accreting millisecond pulsar IGR J00291+5934 using RXTE data taken during the outburst of December 2004. We corrected the arrival times of all the events for the orbital (Doppler) effects and performed a timing analysis of the resulting phase delays. In this way we have the possibility to study, for the first time in this class of sources, the spin-up of a millisecond pulsar as a consequence of accretion torques during the X-ray outburst. The accretion torque gives us for the first time an independent estimate of the mass accretion rate onto the neutron star, which can be compared with the observed X-ray luminosity. We also report a revised valu…

Oltre le parole: le relazioni intersoggettive nei nidi d’infanzia e la formazione delle educatrici

2017

In questo articolo mi soffermo in particolare, sulle interazioni e sui legami affettivi ed emotivi tra adulti e bambini, ma anche tra bambini e bambini, all'interno dei nidi d'infanzia, focalizzandomi sulla intercorporeità. Farò riferimento in particolare alle prospettive dell’infant research, dell’intersoggettività e delle neuroscienze secondo un “approccio in seconda persona”. Concluderò con una riflessione sulla formazione degli educatori per l’infanzia alla luce di quanto sostenuto, sottolineando la necessità di percorsi specifici e adeguati alla delicatezza ed alla complessità del ruolo svolto nella crescita dei bambini.

CALIBRATION OF LÉVY PROCESSES USING OPTIMAL CONTROL OF KOLMOGOROV EQUATIONS WITH PERIODIC BOUNDARY CONDITIONS

2018

We present an optimal control approach to the problem of model calibration for L\'evy processes based on a non parametric estimation procedure. The calibration problem is of considerable interest in mathematical finance and beyond. Calibration of L\'evy processes is particularly challenging as the jump distribution is given by an arbitrary L\'evy measure, which form a infinite dimensional space. In this work, we follow an approach which is related to the maximum likelihood theory of sieves. The sampling of the L\'evy process is modelled as independent observations of the stochastic process at some terminal time $T$. We use a generic spline discretization of the L\'evy jump measure and selec…
