Analysis of climate change impacts on EU agriculture by 2050
The 2013 EU strategy on adaptation to climate change aims at contributing to a more climate-resilient Europe. However, there are still large gaps in understanding and characterising climate impacts in Europe and how impacts in the rest of the world could affect Europe. This report provides quantitative modelling-based results from biophysical and agro-economic models as part of the PESETA-IV (Projection of Economic impacts of climate change in Sectors of the European Union based on bottom-up Analysis) project. We analyse climate change projections for 2050 considering the Representative Concentration Pathway (RCP) of 8.5 W/m2 (with corresponding global warming levels ranging between 1.6 oC and 2.7 oC compared to pre-industrial levels), as well as for 1.5 °C and 2 °C warming conditions. Results show that climate change will pose a threat to global food production in the medium to long term, and that Europe will also be affected. Forced by the projected changes in daily temperature, precipitation, wind, relative humidity, and global radiation, grain maize yields in the EU will decline between 1% and 22%. In addition, wheat yields in Southern Europe are expected to decrease by up to 49%. However, in Northern Europe some of the negative productivity effects caused by climate change may be partially offset by higher levels of atmospheric CO2 concentrations and changing precipitation regimes. Losses, especially in Southern Europe may be reduced by tailored adaptation strategies; e.g. changing varieties and crop types, increasing and improving irrigation practices for certain crops and when economically feasible. However, limitations on sustainable water abstraction levels could become a barrier to increase irrigation levels, specifically in the Mediterranean countries (particularly Spain, Portugal, Greece, Cyprus, Malta, Italy and Turkey) where duration of water scarcity under global warming are projected to intensify. As large negative climate change impacts on productivity outside of the EU are estimated, large market spill-over effects will push up production in both Northern and Southern Europe through higher demand for some agricultural commodities outside of EU, resulting in higher producer prices. This, in turn, may benefit farmers' income and have positive effects on the EU’s agricultural commodity exports. However, other limiting factors (not all fully integrated into the used modelling system yet), such as increasing water shortage in Southern Europe (Task 10) and constraints on the expansion of irrigation, increasing impacts of heatwaves and droughts, consequences of reduction of nutrient use due to environmental and climate mitigation constraints, need to be further evaluated.JRC.D.4-Economics of Agricultur

Shoc2/Sur8 protein regulates neurite outgrowth
This is an openaccess
article distributed under the terms of the
Creative Commons Attribution License.-- et al.The Shoc2 protein has been implicated in the positive regulation of the Ras-ERK pathway by increasing the functional binding interaction between Ras and Raf, leading to increased ERK activity. Here we found that Shoc2 overexpression induced sustained ERK phosphorylation, notably in the case of EGF stimulation, and Shoc2 knockdown inhibited ERK activation. We demonstrate that ectopic overexpression of human Shoc2 in PC12 cells significantly promotes neurite extension in the presence of EGF, a stimulus that induces proliferation rather than differentiation in these cells. Finally, Shoc2 depletion reduces both NGF-induced neurite outgrowth and ERK activation in PC12 cells. Our data indicate that Shoc2 is essential to modulate the Ras-ERK signaling outcome in cell differentiation processes involved in neurite outgrowth.GL, TG and LMD were recipients of fellowships from the Ministerio de Educación y Ciencia (MEC) (to GL, TG), and Fondo de Investigaciones Sanitarias (FIS) (to LMD).

Performance of CMS muon reconstruction in pp collision events at sqrt(s) = 7 TeV
The performance of muon reconstruction, identification, and triggering in CMS
has been studied using 40 inverse picobarns of data collected in pp collisions
at sqrt(s) = 7 TeV at the LHC in 2010. A few benchmark sets of selection
criteria covering a wide range of physics analysis needs have been examined.
For all considered selections, the efficiency to reconstruct and identify a
muon with a transverse momentum pT larger than a few GeV is above 95% over the
whole region of pseudorapidity covered by the CMS muon system, abs(eta) < 2.4,
while the probability to misidentify a hadron as a muon is well below 1%. The
efficiency to trigger on single muons with pT above a few GeV is higher than
90% over the full eta range, and typically substantially better. The overall
momentum scale is measured to a precision of 0.2% with muons from Z decays. The
transverse momentum resolution varies from 1% to 6% depending on pseudorapidity
for muons with pT below 100 GeV and, using cosmic rays, it is shown to be
better than 10% in the central region up to pT = 1 TeV. Observed distributions
of all quantities are well reproduced by the Monte Carlo simulation.Comment: Replaced with published version. Added journal reference and DO

Azimuthal anisotropy of charged particles at high transverse momenta in PbPb collisions at sqrt(s[NN]) = 2.76 TeV
The azimuthal anisotropy of charged particles in PbPb collisions at
nucleon-nucleon center-of-mass energy of 2.76 TeV is measured with the CMS
detector at the LHC over an extended transverse momentum (pt) range up to
approximately 60 GeV. The data cover both the low-pt region associated with
hydrodynamic flow phenomena and the high-pt region where the anisotropies may
reflect the path-length dependence of parton energy loss in the created medium.
The anisotropy parameter (v2) of the particles is extracted by correlating
charged tracks with respect to the event-plane reconstructed by using the
energy deposited in forward-angle calorimeters. For the six bins of collision
centrality studied, spanning the range of 0-60% most-central events, the
observed v2 values are found to first increase with pt, reaching a maximum
around pt = 3 GeV, and then to gradually decrease to almost zero, with the
decline persisting up to at least pt = 40 GeV over the full centrality range
measured.Comment: Replaced with published version. Added journal reference and DO
Search for new physics with same-sign isolated dilepton events with jets and missing transverse energy
A search for new physics is performed in events with two same-sign isolated
leptons, hadronic jets, and missing transverse energy in the final state. The
analysis is based on a data sample corresponding to an integrated luminosity of
4.98 inverse femtobarns produced in pp collisions at a center-of-mass energy of
7 TeV collected by the CMS experiment at the LHC. This constitutes a factor of
140 increase in integrated luminosity over previously published results. The
observed yields agree with the standard model predictions and thus no evidence
for new physics is found. The observations are used to set upper limits on
possible new physics contributions and to constrain supersymmetric models. To
facilitate the interpretation of the data in a broader range of new physics
scenarios, information on the event selection, detector response, and
efficiencies is provided.Comment: Published in Physical Review Letter
