Last Interglacial sea-level proxies in the western Mediterranean
No full textWe describe a database of Last Interglacial (Marine Isotopic Stage 5) sea-level proxies for the western Mediterranean region. The database was compiled reviewing the information reported in 199 published studies and contains 396 sea-level data points (sea-level index points and marine- or terrestrial-limiting points) and 401 associated dated samples. The database follows the standardized WALIS template and is available as Cerrone et al. (2021b, https://doi.org/10.5281/zenodo.5341661)
Banking Regulation for ESG Principles and Climate Risk
No full textNowadays banking activity is greatly influenced by environmental and social
conditions. For this reason, regulators have been committed to defining Environment,
Social, and Governance (ESG) principles. In addition, climate change has shown the
relevance of climate risks that have relevant implications in the new risk management
process. The 2030 Agenda for Sustainable Development is based on the 17 SDGs that
are, in the next future, the main challenge for the worldwide economy as they will be
the basis for real sustainable activities. In this context, banks play a very relevant role
as they have the power to lead this new challenge and are able to facilitate businesses
to run toward a sustainable green economy. For this reason, banks’ activity is now
oriented to increase and allocate credit and investment to more sustainable sectors.
As climate risk is, at the same time, cause and effect for a socially responsible activity,
regulators have been considering the role of banks for the green and ecological transition,
which is necessary to face this new risk. The chapter is an overview of rules,
regulations, and guidelines for banks referred to ESG principles and their adoption
in a global perspective; it also refers to climate risk that, due to its components, may
require further capital to preserve banks’ stability
Vicende istituzionali ed epigrafia a Casinum
No full textThe institutional framework of Casinum in the 1st century B.C. can be recreated especially thanks to the epigraphic evidence. Some of the inscriptions known in the past and then lost, have been recently found again. The existence of a praefectus sent by the urban praetor in uncertain before the Social War; afterwards Casinum was a duoviral municipium until the colony was deducted not before the second half of the 1st century A.D. We don't know the original name of the magistrates (praetores?), but after the Social War the duoviri were generally elected every year. The C. Futius praefectus Casinatium mentioned in CIL, X 5193-5194, probably could be due to a lacking election of the duoviri in the mid. 1st century B.C., which caused the decurions to elected a local notable responsible for the administration of the city. The function exercited by C. Futius can however also be interpreted differently, because it remains indeterminable due to lack of other sources in this regard
Surface uplift and sea level change: constraints from Late Pleistocene paleoshorelines
No full textThe aims of this PhD research project are both a reconstruction of the surface
uplift of the Tyrrhenian coastal side of the southern Apennines in the Middle-Late
Pleistocene time span and a field data acquisition on Relative Sea Level (RSL)
indicators in order to better constrain the sea level change for the western sector of
the Mediterranean. The field study has been based on detail scale morphotectonic
and stratigraphic analyses, which have been carried out by geomorphological
analyses on topographic maps and Digital Elevation Models (DEM), on two key
areas of the Tyrrhenian coast: the Campania Plain margin and the Basilicatanorthern
Calabria area. The morphostratigraphical analyses have been integrated
by new U-series dating of calcite deposits (speleothems and a calcite vein) and
coral C. caespitosa samples. The main topics and results can be summarised as
follows:
A study of formerly known and new outcrops of marine terraces has
been carried out in the NE margin of the Campania Plain (Fellino
Mt.), a Quaternary coastal graben located in the Tyrrhenian side of
the southern Apennines;
• Raised paleoshorelines assigned to two raised paleoshorelines
(labelled T1 and T2) were detected along Fellino Mt. at variable
elevation;
• The synchronous correlation method, based on U-series dating on a
calcite vein post-dating the age of T2 terrace, allow relating the T2
and T1 identified paleoshoreline to MIS 9 and MIS 7 respectively;
• Structural data collection allow defining the geometry and kinematics
of the main Quaternary structures filling, hence, the existing gap
along the borders of the Campania plain. The study reports the first
field evidence of Quaternary extensional tectonics affecting the Campania Plain borders. The identified paleoshorelines are displaced
by a major extensional fault zone c. E-W oriented (namely Polvica
Fault), and several faults c. N-S and NW-SE oriented with less
displacements;
• The uplift fault-related rate of the Polvica Fault, the throw rate and
the Earthquake Recurrence Interval (ERI) have been estimated in c.
02-06 mm/y range, 0.4 mm/y and c. 1100 y respectively. The uplift
rate is characterised by a spatially variation along the strike of the
Polvica Fault;
A flight of paleoshorelines up to c. 60 m a.s.l. located along the
Tyrrhenian sector of the Basilicata - northern Calabria has been
investigated by detailed geomorphological-stratigraphical analyses.
The flight of paleoshorelines has been constrained in the early 1990s
with AAR and U-series dating but the new U-series dating provided
in this study has allowed the reconstruction of a chronological
framework for the analysed sea level markers. The U- series dating
have been performed on C. caespitosa corals and calcite concretions,
either predating or postdating the paleoshorelines. In particular, the
U-series dating allow correlating the T1 terrace at 5 m a.s.l. to the
MIS 6e, the T2 at c. 16 m to MIS 5c, the T3 terrace at c 22 m a.s.l. to
MIS 5a, the T4 terrace at 35 m .s.l. to the MIS 5e and the higher T5
terrace to MIS 7. The new findings shed light on the Quaternary
evolution of the Basilicata area – northern Calabria;
• A Relative sea level (RSL) curve during the Middle-Late Pleistocene
time span for the northern Calabria-Basilicata Tyrrhenian sector has
been constructed;
A mean uplift rate of 0.235 ± 0.01 mm/y since the Last Interglacial
has been evaluated. The uplift rate is one order of magnitude larger
than estimation based on former dating;
• The new data provide new constraints to both the long term evolution
of the Tyrrhenian margin of the southern Apennines and the late
Quaternary sea level fluctuations in the western Mediterranean. The
elevation of MIS 5a, 5c and 6e peaks and the time span of 5a have
been evaluated. Such elevations may better constrain ice sheets
volume variation during the late Quaternary.
• The geomorphological reconstruction has demonstrated that a mere
sequential correlation may be misleading in the interpretation of
flights of marine terraces, and indicates that multiple age controls are
crucial to unravelling the complex interaction between uplift and sea
level fluctuations in uplifted coastal areas;
A review of MIS 5 paleoshorelines along the western Mediterranean
(Spain, France, Italy, Istria, Kvarner and Dalmatia, Algeria and
Morocco) has been compiled in the framework of the Word Atlas of
Last Interglacial Shorelines (WALIS)
Characterization of JUNO Large-PMT electronics in a complete small scale test setup
No full textThe Jiangmen Underground Neutrino Observatory (JUNO) is a neutrino medium baseline experiment under construction in southern China. The experiment has been proposed with the main goals of determining the neutrino mass ordering and measuring the oscillation parameters with sub-percent precision. To reach these goals, JUNO is located about 53 km from two nuclear power plants and will detect electron antineutrinos from reactors through inverse beta decay. Furthermore, an unprecedented energy resolution of 3 % at 1 MeV is required. The JUNO detector consists of 20 kt of liquid scintillator (LS) contained in a 17.7 m radius acrylic vessel, which is instrumented with a system of 17 612 20-inch Large-PMTs and 25 600 3-inch Small-PMTs, with a total photo-coverage greater than 75 %. Additionally, 2400 Large-PMTs are installed in the instrumented Water Pool detector. The signal from the Large-PMTs is processed by the JUNO electronics system, which can be divided into two main parts: the front-en..

The Technological Disruption in Banking Sector - New Efforts and Challenges in the Financial Business Models
No full textThe disruptive technologies radically transform business models and create new innovative products and services. The chapter, focused on the technological disruption in banks, considers: • the assessment of technology impact, including the spread of artificial intelligence, at the level of business models and the relevance for regulators and supervisors, interested in granting a safe and sound banking system; • the main risks associated with technology considered in banking business models;• future perspectives for new strategies and business models with a transition from linear vertically-integrated models to non-linear adaptive models. The chapter outlines the state of the art in the banking services and the organizational responses, highlighting the needs not yet solved in banks' operations, but projected towards the near future, already present. The Appendix offers a framework of the banks’ approach to technology through the answers given by the sample of European banks to questions about technology in EBA’s RAQ
Locating sensors to observe network arc flows: Exact and heuristic approaches
No full textThe problem of optimally locating sensors on a traffic network to monitor flows has been an object of growing interest in the past few years, due to its relevance in the field of traffic management and control. Sensors are often located in a network in order to observe and record traffic flows on arcs and/or nodes. Given traffic levels on arcs within the range or covered by the sensors, traffic levels on unobserved portions of a network can then be computed. In this paper, the problem of identifying a sensor configuration of minimal size that would permit traffic on any unobserved arcs to be exactly inferred is discussed. The problem being addressed, which is referred to in the literature as the Sensor Location Problem (SLP), is known to be NP-complete, and the existing studies about the problem analyze some polynomial cases and present local search heuristics to solve it. In this paper we further extend the study of the problem by providing a mathematical formulation that up to now has been still missing in the literature and present an exact branch and bound approach, based on a binary branching rule, that embeds the existing heuristics to obtain bounds on the solution value. Moreover, we apply a genetic approach to find good quality solutions. Extended computational results show the effectiveness of the proposed approaches in solving medium-large instances
Catecholaminergic polymorphic ventricular tachycardia: A paradigm to understand mechanisms of arrhythmias associated to impaired Ca(2+) regulation
No full textIn the 8 years since the discovery of the genetic bases of catecholaminergic polymorphic ventricular tachycardia (CPVT), we have witnessed a remarkable improvement of knowledge on arrhythmogenic mechanisms involving disruption of cardiac Ca(2+) homeostasis. Studies on the consequences of RyR2 and CASQ2 mutations in cellular systems and mouse models have shed new light on pathways that are also implicated in arrhythmias occurring in highly prevalent diseases, such as heart failure. This research track has also led to the identification of therapeutic targets of potential clinical impact to abate the burden of sudden death in CPVT. Here, we review the current knowledge on the pathophysiology of CPVT also highlighting the existing controversies and possible future development
