Reduced Visual Cortex Gray Matter Volume and Thickness in Young Adults Who Witnessed Domestic Violence during Childhood
Exposure to interparental violence is associated with negative outcomes, such as depression, post-traumatic stress disorder and reduced cognitive abilities. However, little is known about the potential effects of witnessing domestic violence during childhood on gray matter volume (GMV) or cortical thickness. High-resolution 3.0 T volumetric scans (Siemens Trio Scanner) were obtained on 52 subjects (18–25 years) including 22 (6 males/16 females) with a history of visually witnessing episodes of domestic violence, and 30 (8 males/22 females) unexposed control subjects, with neither a current nor past DSM-IV Axis I or II disorder. Potential confounding effects of age, gender, level of parental verbal aggression, parental education, financial stress, full scale IQ, and total GMV, or average thickness were modeled using voxel based morphometry and FreeSurfer. Witnessing domestic violence subjects had a 6.1% GMV reduction in the right lingual gyrus (BA18) (P = 0.029, False Discovery Rate corrected peak level). Thickness in this region was also reduced, as was thickness in V2 bilaterally and left occipital pole. Theses regions were maximally sensitive to exposure to witnessing domestic violence between 11–13 years of age. Regional reductions in GMV and thickness were observed in both susceptible and resilient witnessing domestic violence subjects. Results in subjects witnessing domestic violence were similar to previously reported results in subjects with childhood sexual abuse, as the primary region affected was visual cortex. Brain regions that process and convey the adverse sensory input of the abuse may be specifically modified by this experience, particularly in subjects exposed to a single type of maltreatment. Exposure to multiple types of maltreatment is more commonly associated with morphological alterations in corticolimbic regions. These findings fit with preclinical studies showing that visual cortex is a highly plastic structure
Subsidence Detected by Multi-Pass Differential SAR Interferometry in the Cassino Plain (Central Italy): Joint Effect of Geological and Anthropogenic Factors?
In the present work, the Differential SAR Interferometry (DInSAR) technique has
been applied to study the surface movements affecting the sedimentary basin of Cassino
municipality. Two datasets of SAR images, provided by ERS 1-2 and Envisat missions, have
been acquired from 1992 to 2010. Such datasets have been processed independently each other
and with different techniques nevertheless providing compatible results. DInSAR data show a
subsidence rate mostly located in the northeast side of the city, with a subsidence rate
decreasing from about 5–6 mm/yr in the period 1992–2000 to about 1–2 mm/yr between 2004
and 2010, highlighting a progressive reduction of the phenomenon. Based on interferometric
results and geological/geotechnical observations, the explanation of the detected movements
allows to confirm the anthropogenic (surface effect due to building construction) and
geological causes (thickness and characteristics of the compressible stratum
Experimental realization of a relativistic fluxon ratchet
We report the observation of the ratchet effect for a relativistic flux
quantum trapped in an annular Josephson junction embedded in an inhomogeneous
magnetic field. In such a solid state system mechanical quantities are
proportional to electrical quantities, so that the ratchet effect represents
the realization of a relativistic-flux-quantum-based diode. Mean static voltage
response, equivalent to directed fluxon motion, is experimentally demonstrated
in such a diode for deterministic current forcing both in the overdamped and in
the underdamped dynamical regime. In the underdamped regime, the recently
predicted phenomenon of current reversal is also recovered in our fluxon
ratchet.Comment: 4 pages, 6 figures. To appear in PHYSICA
Assessing the volcanic hazard for Rome. 40Ar/39Ar and In-SAR constraints on the most recent eruptive activity and present-day uplift at Colli Albani Volcanic District
We present new 40Ar/39Ar data which allow us to refine the recurrence time for the most recent eruptive activity occurred at Colli Albani Volcanic District (CAVD) and constrain its geographic area. Time elapsed since the last eruption (36 kyr) overruns the recurrence time (31 kyr) in the last 100 kyr. New interferometric synthetic aperture radar data, covering the years 1993–2010, reveal ongoing inflation with maximum uplift rates (>2 mm/yr) in the area hosting the most recent (<200 ka) vents, suggesting that the observed uplift might be caused by magma injection within the youngest plumbing system. Finally, we frame the present deformation within the structural pattern of the area of Rome, characterized by 50 m of regional uplift since 200 ka and by geologic evidence for a recent (<2000 years) switch of the local stress-field, highlighting that the precursors of a new phase of volcanic activity are likely occurring at the CAVD
Geodetic model of the 2016 Central Italy earthquake sequence inferred from InSAR and GPS data
We investigate a large geodetic data set of interferometric synthetic aperture radar (InSAR)and GPS measurements to determine the source parameters for the three main shocks of the 2016Central Italy earthquake sequence on 24 August and 26 and 30 October (Mw6.1, 5.9, and 6.5,respectively). Our preferred model is consistent with the activation of four main coseismic asperitiesbelonging to the SW dipping normal fault system associated with the Mount Gorzano-Mount Vettore-Mount Bove alignment. Additional slip, equivalent to aMw~ 6.1–6.2 earthquake, on a secondary (1) NEdipping antithetic fault and/or (2) on a WNW dipping low-angle fault in the hanging wall of the mainsystem is required to better reproduce the complex deformation pattern associated with the greatestseismic event (theMw6.5 earthquake). The recognition of ancillary faults involved in the sequencesuggests a complex interaction in the activated crustal volume between the main normal faults and thesecondary structures and a partitioning of strain releas
RICAMAR2013: Rilievi per la caratterizzazione dell\u27ambiente marino nel Golfo di Pozzuoli. Rapporto sull\u27attivita 13 - 31 maggio 2013
Rapporto sull’attività 13 – 31 maggio 2013
La caldera risorgente dei Campi Flegrei è, insieme ai vulcani Somma-Vesuvio, Ischia e Procida, uno
degli elementi dominanti dell’assetto geologico e morfologico dell’area napoletana. Si tratta di un sistema
vulcanico ancora attivo la cui persistente attività è testimoniata dall’ultima eruzione, avvenuta nel 1538,
dall’intensa attività fumarolica e idrotermale che perdura da millenni e dai frequenti eventi bradisismici, con
deformazione del suolo accompagnata da sismicità e variazioni delle caratteristiche chimico-fisiche dei fluidi
emessi dalle fumarole. La caldera comprende la parte occidentale della città di Napoli e si estende nel Golfo
di Pozzuoli. La caratteristica principale dell’attuale attività vulcanica della caldera è il movimento lento del
suolo a carattere episodico e di grande ampiezza (bradisismo), accompagnato da un’intensa e superficiale
attività sismica che si verifica in generale durante la fase di sollevamento......Istituto Nazionale di Geofisica e Vulcanologia - Marina Militare ItalianaPublished6A. Monitoraggio ambientale, sicurezza e territorioope
