Loss Database Architecture for Disaster Risk Management
The reformed Union civil protection legislation (Decision on a Union Civil Protection Mechanism), which entered into force on 1 January 2014, is paving the way for more resilient communities by including key actions related to disaster prevention such as developing national risk assessments and the refinement of risk management planning. Under the Decision, Member States agreed to “develop risk assessments at national or appropriate sub- national level and make available to the Commission a summary of the relevant elements thereof by 22 December 2015 and every three years thereafter”. The Decision also requires Member States, together with the Commission, to develop guidelines on the content, methodology, and structure of risk management capability assessments. The Commission has published risk assessment and risk mapping guidelines to assist Member States with their national risk assessments. Risk management capability assessment guidelines were also developed.
The recent Communication from the Commission "Strengthening EU Disaster Management: rescEU -Solidarity with Responsibility" COM(2017) 773 final calls "Member States and Commission to promote more systematic collection and dissemination of loss data, to enhance the collection of loss data and make use of loss data for optimised prevention and climate adaptation planning".
Systematically collected, comparable and robust disaster damage and loss data are an essential element of the risk assessment and management processes. Thus, the Council Conclusions on risk management capability call on the Commission to 'Encourage the development of systems, models or methodologies for collecting and exchanging data on ways to assess the economic impact of disasters on an all-hazard basis.'
The current practice in disaster loss data recording across the EU shows that there are hardly any comparable disaster damage and loss data: differences exist in the methods of data recording as well as in the governance approaches to managing disaster damage and loss data. The lack of standards for damage and loss data collection and recording represent the main challenge for damage and loss data sharing and comparison, especially for cross-border cooperation within the EU.
This report is based on an accurate analysis of several databases developed following a diversified number of purposes to collect, record and aggregate information regarding losses occurred after a shock triggered by different hazards. The report proposes a common structure of a generic database able to accommodate and properly record the required particularities of a vast variety of events triggered by any kind of hazard.JRC.E.1-Disaster Risk Managemen

The Risk Data Hub loss datasets
The aim of this document is to report the methodology used to create the Historic Events module and the use that can be done of damage and loss data.
The RDH Historical Event Catalogue consists in a collection of past events data occurred in EU created from a wide array of data published in several sources and datasets. This collection makes use of inventoried data; precisely different open access datasets have been interrogated collecting European-related records on past disastrous events. Both hazard and loss data have been systematically collected from various sources, checked, linked and homogenized to be provided in tabular and geospatial format in order to create the RDH Historical Event Catalogue.
The work carried out consists in an effort done to improve the existing lack of homogeneous and comparable data on past events occurred across European Countries. This work represents an assemblage of sources that become complementary. Considering that each source focuses on different aspects of the impact events, the objective of the collection is to describe the phenomenon, gather data on loss and damage records and present the spatial extent of the damages. Finally, analyses intended to illustrate ways of examining global loss data and identifying possible trends in terms of peril or geographical prone areas within the European Countries are performed on the collected damage and loss data.JRC.E.1-Disaster Risk Managemen
Observation of two new baryon resonances
Two structures are observed close to the kinematic threshold in the mass spectrum in a sample of proton-proton collision data, corresponding
to an integrated luminosity of 3.0 fb recorded by the LHCb experiment.
In the quark model, two baryonic resonances with quark content are
expected in this mass region: the spin-parity and
states, denoted and .
Interpreting the structures as these resonances, we measure the mass
differences and the width of the heavier state to be
MeV,
MeV,
MeV, where the first and second
uncertainties are statistical and systematic, respectively. The width of the
lighter state is consistent with zero, and we place an upper limit of
MeV at 95% confidence level. Relative
production rates of these states are also reported.Comment: 17 pages, 2 figure
Measurement of the mass and lifetime of the baryon
A proton-proton collision data sample, corresponding to an integrated
luminosity of 3 fb collected by LHCb at and 8 TeV, is used
to reconstruct , decays. Using the , decay mode for calibration, the lifetime ratio and absolute
lifetime of the baryon are measured to be \begin{align*}
\frac{\tau_{\Omega_b^-}}{\tau_{\Xi_b^-}} &= 1.11\pm0.16\pm0.03, \\
\tau_{\Omega_b^-} &= 1.78\pm0.26\pm0.05\pm0.06~{\rm ps}, \end{align*} where the
uncertainties are statistical, systematic and from the calibration mode (for
only). A measurement is also made of the mass difference,
, and the corresponding mass, which
yields \begin{align*} m_{\Omega_b^-}-m_{\Xi_b^-} &= 247.4\pm3.2\pm0.5~{\rm
MeV}/c^2, \\ m_{\Omega_b^-} &= 6045.1\pm3.2\pm 0.5\pm0.6~{\rm MeV}/c^2.
\end{align*} These results are consistent with previous measurements.Comment: 11 pages, 5 figures, All figures and tables, along with any

Study of and decays and determination of the CKM angle
We report a study of the suppressed and favored
decays, where the neutral meson is detected
through its decays to the and CP-even and
final states. The measurement is carried out using a proton-proton
collision data sample collected by the LHCb experiment, corresponding to an
integrated luminosity of 3.0~fb. We observe the first significant
signals in the CP-even final states of the meson for both the suppressed
and favored modes, as well as
in the doubly Cabibbo-suppressed final state of the decay. Evidence for the ADS suppressed decay , with , is also presented. From the observed
yields in the , and their
charge conjugate decay modes, we measure the value of the weak phase to be

single-measurement determinations of to date.Comment: 22 pages, 9 figures; All figures and tables, along with any

measured to be \begin{equation*} \mathcal{B}(\Lambda_b^0\rightarrow J/\psi
pK^-)= (3.17\pm0.04\pm0.07\pm0.34^{+0.45}_{-0.28})\times10^{-4},
\end{equation*} where the first uncertainty is statistical, the second is
systematic, the third is due to the uncertainty on the branching fraction of
the decay , and the
fourth is due to the knowledge of . The sum of the
asymmetries in the production and decay between and

Differential branching fraction and angular analysis of the decay B0→K∗0μ+μ−
The angular distribution and differential branching fraction of the decay B 0→ K ∗0 μ + μ − are studied using a data sample, collected by the LHCb experiment in pp collisions at s√=7 TeV, corresponding to an integrated luminosity of 1.0 fb−1. Several angular observables are measured in bins of the dimuon invariant mass squared, q 2. A first measurement of the zero-crossing point of the forward-backward asymmetry of the dimuon system is also presented. The zero-crossing point is measured to be q20=4.9±0.9GeV2/c4 , where the uncertainty is the sum of statistical and systematic uncertainties. The results are consistent with the Standard Model predictions

Evidence for the strangeness-changing weak decay
Using a collision data sample corresponding to an integrated luminosity
of 3.0~fb, collected by the LHCb detector, we present the first search
for the strangeness-changing weak decay . No
hadron decay of this type has been seen before. A signal for this decay,
corresponding to a significance of 3.2 standard deviations, is reported. The
