Mining discharge letters for diagnoses validation and quality assessment
We present two projects where text mining techniques are applied to free text documents written by clinicians. In the first, text mining is applied to discharge letters related to patients with diag-noses of acute myocardial infarction (by ICD9CM coding). The aim is extracting information on diagnoses to validate them and to integrate administrative databases. In the second, text mining is applied to discharge letters related to patients that received a diagnosis of heart failure (by ICD9CM coding). The aim is assessing the presence of follow-up instructions of doctors to patients, as an aspect of information continuity and of the continuity and quality of care. Results show that text mining is a promising tool both for diagnoses validation and quality of care as-sessment
Recent direct reaction experimental studies with radioactive tin beams
Direct reaction techniques are powerful tools to study the single-particle
nature of nuclei. Performing direct reactions on short-lived nuclei requires
radioactive ion beams produced either via fragmentation or the Isotope
Separation OnLine (ISOL) method. Some of the most interesting regions to study
with direct reactions are close to the magic numbers where changes in shell
structure can be tracked. These changes can impact the final abundances of
explosive nucleosynthesis. The structure of the chain of tin isotopes is
strongly influenced by the Z=50 proton shell closure, as well as the neutron
shell closures lying in the neutron-rich, N=82, and neutron-deficient, N=50,
regions. Here we present two examples of direct reactions on exotic tin
isotopes. The first uses a one-neutron transfer reaction and a low-energy
reaccelerated ISOL beam to study states in 131Sn from across the N=82 shell
closure. The second example utilizes a one-neutron knockout reaction on
fragmentation beams of neutron-deficient 106,108Sn. In both cases, measurements
of gamma rays in coincidence with charged particles proved to be invaluable.Comment: 11 pages, 5 figures, Zakopane Conference on Nuclear Physics "Extremes

SEEMP: A Semantic Interoperability Infrastructure for e-government services in the employment sector
This paper presents SEEMP, a marketplace to coordinate
and integrate public and private employment services (ESs) around the
EU Member States. The need for flexible collaboration in the marketplace
gives rise to the issue of interoperability in both data exchange and
share of services. SEEMP proposes a mixed approach that relies on the
concepts of services and semantics. SEEMP approach combines Software
Engineering and Semantic Web methodologies/tools in an infrastructure
that allows for a meaningful service-based communication among ESs
SEEMP: A marketplace for the Labour Market
Employment Services are an important topic in the agenda of local governments and in the EU due to their social implications, such as sustainability, workforce mobility, workers’ re-qualification paths, training for fresh graduates and students. Many administrations started their own E-Government projects whose imitations emerge as the demand of workers mobility increases. The SEEMP system presented in this paper overcomes this issue in different ways: starting bilateral communications with near-border similar offices, building a federation of the local employment services, and merging isolate trials. The SEEMP approach relies on a distributed semantic service oriented infrastructure able to federate local projects, in order to create geographically aggregated services for employment by leveraging existing local ones. The social and technical aspects of the SEEMP project are presented, showing how the SEEMP system is integrated with National level systems
The SEEMP Approach to Semantic Interoperability for E-Employment
SEEMP is a European Project that promotes increased partnership between labour market actors and the development of closer relations between private and public employment services, making optimal use of the various actors’ specific characteristics, thus providing job-seekers and employers with better services. The need for a flexible collaboration gives rise to the issue of interoperability in both data exchange and share of services. SEEMP proposes a solution that relies on the concepts of services and semantics in order to provide a meaningful service-based communication among labour market actors requiring a minimal shared commitment

A Search for Dark Higgs Bosons
Recent astrophysical and terrestrial experiments have motivated the proposal
of a dark sector with GeV-scale gauge boson force carriers and new Higgs
bosons. We present a search for a dark Higgs boson using 516 fb-1 of data
collected with the BABAR detector. We do not observe a significant signal and
we set 90% confidence level upper limits on the product of the Standard
Model-dark sector mixing angle and the dark sector coupling constant.Comment: 7 pages, 5 postscript figures, published version with improved plots
