CHILD INHUMATIONS ON THE ISLAND OF MOTYA. NEW EVIDENCE FROM THE ARCHAIC CEMETERY
2020
The aim of this paper is to shed light on the interpretation of human remains and funerary rituals recently uncovered in the Archaic Necropolis of Motya. During the 20th century about 350 graves were brought to light by earlier explorations, showing that – apart from rare exceptions – adult cremation was the most common rite performed in archaic times (ca. 730-550 BC). This picture can be now changed in the light of the results of our recent fieldwork (seasons 2013-2017), showing that a large quantity of graves strikingly house remains of sub-adult individuals (i.e. foetuses, perinatals and children). While a few of them are cremated, the numerous inhumations recovered show clear patterns o…

Josephson-junction-based axion detection through resonant activation
2022
We discuss the resonant activation phenomenon on a Josephson junction due to the coupling of the Josephson system with axions. We show how such an effect can be exploited for axion detection. A nonmonotonic behavior, with a minimum, of the mean switching time from the superconducting to the resistive state versus the ratio of the axion energy and the Josephson plasma energy is found. We demonstrate how variations in switching times make it possible to detect the presence of the axion field. An experimental protocol for observing axions through their coupling with a Josephson system is proposed.
Generation of travelling sine-Gordon breathers in noisy long Josephson junctions
2022
The generation of travelling sine-Gordon breathers is achieved through the nonlinear supratransmission effect in a magnetically driven long Josephson junction, in the presence of losses, a current bias, and a thermal noise source. We demonstrate how to exclusively induce breather modes by means of controlled magnetic pulses. A nonmonotonic behavior of the breather-only generation probability is observed as a function of the noise intensity. An experimental protocol providing evidence of the Josephson breather's existence is proposed.
Effects of radiation in accretion regions of classical T Tauri stars
2019
Context. Models and observations indicate that the impact of matter accreting onto the surface of young stars produces regions at the base of accretion columns where optically thin and thick plasma components coexist. Thus, an accurate description of these impacts is necessary to account for the effects of absorption and emission of radiation. Aims. We study the effects of radiation emerging from shock-heated plasma in impact regions on the structure of the pre-shock down-falling material. We investigate whether a significant absorption of radiation occurs and if it leads to a pre-shock heating of the accreting gas. Methods. We developed a radiation hydrodynamics model describing an accreti…

Large deep-seated gravitational slide off Ischia volcanic island, Eastern Tyrrhenian sea (Italy)
2014
Ischia island develops at the edge of the shelf area and represents the sub-aerial section of a larger, E-W trending volcanic ridge including others submerged or buried volcanic edifices. In the past decade the island’s offshore has been the object of extensive hydrographic and marine geophysical surveys that have shown the structural complexity of the undersea sections and have overall shown the importance of gravity failures in island’s evolution. In this paper we report a previously unreported deep-seated slump structure and associated surficial mass wasting phenomena which occur off Ischia south-western flank. Recently acquired hydrological and geophysical data lead to identify the morp…
