This study was carried out in the Regional Park of San Rossore (Italy) where we found natural regeneration of Stone pine (Pinus piena L.) in an even-aged stand of pine. The objectives of our study were to characterize the forest structure of the Stone pine stand and to quantify the natural regeneration of pine. Our results show that natural regeneration of P. pinea in the Park of San Rossore is…

Italy was one of the countries severely affected by the Covid-19 pandemic. An analysis of the factors that played a role in the spread of this epidemic is necessary. However, the assessment of which factors may be specific, and which may contribute the most is complex and involves a high degree of uncertainty. The main objective of this study is to evaluate and analyse the statistical associati…
This chapter describes spin-wave excitations in nanosized dots and rings in the presence of the vortex state. The special attention is paid to the manifestation of the competition between exchange and dipolar interactions in the spin-wave spectrum as well as the correlation between the spectrum and the stability of the vortex. The calculation method uses the dynamic matrix for an all-discrete s…
Filter bank multi‐carrier (FBMC) modulation, as a potential candidate for physical data communication in the fifth generation (5G) wireless networks, has been widely investigated. This chapter focuses on the spectral efficiency analysis of FBMC‐based cognitive radio (CR) systems, and spectral efficiency comparison is conducted with another three types of multi‐carrier modulations: orthogo…
