8000 years of coastal changes on a western Mediterranean Island: A multi proxy approach from the Posada plain of Sardinia

A multi-proxy palaeoenvironmental investigation was conducted to reconstruct the Holocene history of coastal landscape change in the lower Posada coastal plain of eastern Sardinia. In this paper, millennial-scale human-sea level-environment interactions are investigated near Posada. Biostratigraphic and palynological approaches were used to interpret the chromo-stratigraphy exhibited by a series of new clothes taken from the coastal plain. This new study elucidates the main palaeoecologiocal changes, phases of shoreline migration and relative sea-level change during the lat 8000 years. The results indicate the major role of sea-level stabilisation and high sediment supply in driving major landscape changes, especially during the Neolithic period (6-4th millennia BC), and the long-term settlement history of this coastal area. It is concluded that human occupation of the coastal plain, from prehistoric to historical times, was most likely constrained by the rapid evolution if this coastal landscape.LR/7 2010 Regione Sardegn

Automated Analysis of MUTEX Algorithms with FASE

In this paper we study the liveness of several MUTEX solutions by representing them as processes in PAFAS s, a CCS-like process algebra with a specific operator for modelling non-blocking reading behaviours. Verification is carried out using the tool FASE, exploiting a correspondence between violations of the liveness property and a special kind of cycles (called catastrophic cycles) in some transition system. We also compare our approach with others in the literature. The aim of this paper is twofold: on the one hand, we want to demonstrate the applicability of FASE to some concrete, meaningful examples; on the other hand, we want to study the impact of introducing non-blocking behaviours in modelling concurrent systems.Comment: In Proceedings GandALF 2011, arXiv:1106.081

Linking worldwide past and present conifer vulnerability

Inventories of species recently extinct or threatened with extinction may be found in global databases. However, despite the large number of published fossil based-studies, specific databases on the vulnerability of species in the past are not available. We compiled a worldwide database of published fossil records of plant range losses over the last 30 ka across all continents. Widespread range losses of plant taxa across all latitudes were identified, with the majority representing gymnosperms. Focusing on conifers, a group of plants with well understood distribution and conservation status, we found that past range losses often overlapped areas where species are endangered at present, suggesting that such areas have been prone to biodiversity loss through time. During phases of past rapid climate change, even areas that currently have low levels of endangered species were affected by plant range losses, in some cases with disappearance of taxa from entire continents, islands or major geographic regions. Integration of modern and palaeoecological data enhance our understanding of the complex processes underlying the modes, rates, and extent of threats to plants under changing climate and increasing human pressure, which is vital information for effective conservation actions

Human peopling of Italian intramontane basins: The early Middle Pleistocene site of Pagliare di Sassa (L’Aquila, central Italy)

Multidisciplinary investigations at Pagliare di Sassa (L’Aquila, central Italy) suggest that the local succession accumulated from the late Early to the early Middle Pleistocene in a lacustrine environment. In the upper part, clastic sediments are part of an alluvial fan prograding into the lake, grading to a braided fluvial system. The pollen record confirms that a significant glacial phase occurred just before the onset of the Jaramillo inversion. These data, coupled with evidence from the nearby but earlier Madonna della Strada sequence, allow reconstruction of part of the environmental evolution of L’Aquila basin before the Jaramillo Subchron. The mammal species of Pagliare di Sassa include Stephanorhinus hundsheimensis, mostly of open environments, already present at Madonna della Strada. The faunal turnover characterizing the Early to Middle Pleistocene transition is indicated by the appearances of taxa typical of the Italian early to middle Galerian faunas, such as Praemegaceros verticornis, together with Megaloceros savini. The occurrence of Mimomys savini together with Microtus ex gr. Microtus hintonigregaloides suggests that this assemblage is earlier than the Isernia La Pineta fauna. A flint implement and a fragmentary herbivore femur with impact scars probably linked to human activity give evidence of the human peopling of intramontane basins of the Apennine chain since the early Middle Pleistocene.Published170-1782.2.

Granulocyte\u2013colony stimulating factor plus plerixafor inpatients with \u2013thalassemia major results in the effective mobilization of primitiveCD34+ cells with specific gene expression profile

Successful gene therapy for \u3b2-thalassemia requires optimal numbers of autologous gene-transduced hematopoietic stem and progenitor cells (HSPCs) with high repopulating capacity. Previous studies suggested superior mobilization in these patients by the combination of granulocyte\u2013colony stimulating factor (G-CSF) plus plerixafor over single agents. We mobilized four adult patients using G-CSF+plerixafor to assess the intra-individual variation of the circulating CD34+ cells number and subtypes preand post-plerixafor administration. The procedure was well-tolerated and the target cell dose of 658.106 CD34+ cells/kg was achieved in three of them with one apheresis procedure. The addition of plerixafor unanimously increased the number of circulating CD34+ cells, and the frequency of the most primitive CD34+ subtypes: CD34+/38- and CD34+/133+/38- as well as the in vitro clonogenic potency. Microarray analyses of CD34+ cells purified from the leukapheresis of one patient mobilized twice, with G-CSF and with G-CSF+plerixafor, highlighted in G-CSF+plerixafor-mobilized CD34+ cells, higher levels of expression genes involved in HSPC motility, homing, and cell cycles. In conclusion, G-CSF+plerixafor in \u3b2-thalassemia patients mobilizes optimal numbers of HSPCs with characteristics that suggest high capacity of engraftment after transplantation
