The Expanded Risk Score in Rheumatoid Arthritis: performance of a disease-specific calculator in comparison with the traditional prediction scores in the assessment of the 10-year risk of cardiovascular disease in patients with rheumatoid arthritis
The increased risk of cardiovascular disease has emerged as a major issue in patients with rheumatoid arthritis – it has been estimated that the cardiovascular disease burden in rheumatoid arthritis is comparable to that of diabetes mellitus
TINITALY/01: a new Triangular Irregular Network of Italy
A new Digital Elevation Model (DEM) of the natural landforms of Italy is presented. A methodology is discussed to
build a DEM over wide areas where elevation data from non-homogeneous (in density and accuracy) input sources
are available. The input elevation data include contour lines and spot heights derived from the Italian Regional topographic
maps, satellite-based global positioning system points, ground based and radar altimetry data. Owing to the
great heterogeneity of the input data density, the DEM format that better preserves the original accuracy is a Triangular
Irregular Network (TIN). A Delaunay-based TIN structure is improved by using the DEST algorithm that enhances
input data by evaluating inferred break-lines. Accordingly to this approach, biased distributions in slopes and
elevations are absent. To prevent discontinuities at the boundary between regions characterized by data with different
resolution a cubic Hermite blending weight S-shaped function is adopted. The TIN of Italy consists of 1.39Ă—109
triangles. The average triangle area ranges from 12 to about 13000 m2 accordingly to different morphologies and different
sources. About 50% of the model has a local average triangle area <500 m2. The vertical accuracy of the obtained
DEM is evaluated by more than 200000 sparse control points. The overall Root Mean Square Error (RMSE)
is less than 3.5 m. The obtained national-scale DEM constitutes an useful support to carry out accurate geomorphological
and geological investigations over large areas. The problem of choosing the best step size in deriving a grid
from a TIN is then discussed and a method to quantify the loss of vertical information is presented as a function of
the grid step. Some examples of DEM application are outlined. Under request, an high resolution stereo image database
of the whole Italian territory (derived from the presented DEM) is available to browse via internet
Seismic lines Offshore Mount Etna (SOME): open database
The Seismic lines Offshore Mount Etna (SOME) database is presented.
It consists of multichannel high-resolution seismic data acquired
in 2005 off-shore Mount Etna (eastern Sicily). We describe first the
acquisition of seismic lines and then the architecture of the data
base. Finally we describe a very basic interpretation of some seismic
lines to provide clear example of the potentiality of the seismic data
sets in addressing relevant issues such as the occurrence of slope
instabilities and the deformation style of the continental margin off
shore mount Etna.PublishedS05572V. Struttura e sistema di alimentazione dei vulcaniJCR Journa
