Search for heavy lepton partners of neutrinos in proton-proton collisions in the context of the type III seesaw mechanism

This is the Pre-print version of the Article. The official publishe version can be accessed from the link below - Copyright @ 2012 ElsevierA search is presented in proton–proton collisions at sqrt(s) = 7TeV for fermionic triplet states expected in type III seesaw models. The search is performed using final states with three isolated charged leptons and an imbalance in transverse momentum. The data, collected with the CMS detector at the LHC, correspond to an integrated luminosity of 4.9 fb−1. No excess of events is observed above the background predicted by the standard model, and the results are interpreted in terms of limits on production cross sections and masses of the heavy partners of the neutrinos in type III seesaw models. Depending on the considered scenarios, lower limits are obtained on the mass of the heavy partner of the neutrino that range from 180 to 210 GeV. These are the first limits on the production of type III seesaw fermionic triplet states reported by an experiment at the LHC.This study is spported by the BMWF and FWF (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MEYS (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); MoER, SF0690030s09 and ERDF (Estonia); Academy of Finland, MEC, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF and WCU (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); MSI (New Zealand); PAEC (Pakistan); MSHE and NSC (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MON, RosAtom, RAS and RFBR (Russia); MSTD (Serbia); SEIDI and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); ThEP, IPST and NECTEC (Thailand); TUBITAK and TAEK (Turkey); NASU (Ukraine); STFC (United Kingdom); DOE and NSF (USA).

Search for a W ' boson decaying to a muon and a neutrino in pp collisions at √s =7 TeV

This is the Pre-Print version of the Article. The official published version can be accessed from the link below - Copyright @ 2011 ElsevierA new heavy gauge boson, W', decaying to a muon and a neutrino, is searched for in pp collisions at a centre-of-mass of 7 TeV. The data, collected with the CMS detector at the LHC, correspond to an integrated luminosity of 36 inverse picobarns. No significant excess of events above the standard model expectation is found in the transverse mass distribution of the muon-neutrino system. Masses below 1.40 TeV are excluded at the 95% confidence level for a sequential standard-model-like W'. The W' mass lower limit increases to 1.58 TeV when the present analysis is combined with the CMS result for the electron channel.This work is supported by the FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF and WCU (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTD (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)

Beta-blockers reduce myocardial brain natriuretic peptide release after coronary artery bypass grafts

Background. It has been observed that in patients with ST-elevation myocardial infarction (STEMI) the presence of ST-segment depression (ST↓) in heterozonal electrocardiographic leads (remote ST↓) worsens the patient's prognosis. The aim of this study was to observe in an unselected population with a first STEMI the incidence of remote ST↓ and the risk factors related to this condition. Methods. We evaluated retrospectively 350 patients with a first STEMI; we excluded from our analysis 139 patients because no data about their coronary anatomy was available. ST-segment depression in the heterozonal myocardium was considered significant if >0.1 mV at 60 ms from the J point, in at least two electrocardiographic leads. Results. Patients were classified according to the presence (group I, 117 patients) or absence (group II, 94 patients) of remote ST↓. The two groups did not differ for age, sex and coronary anatomy. In group I we found more heterozonal wall motion abnormalities than group II (32 vs; 18%, p = 0.018). In this group there was a higher incidence of smokers (56 vs 33%, p = 0.025) and less patients were treated with statins when the STEMI occurred (6 vs 14%, p = 0.047). Patients with remote ST↓ had higher total cholesterol (214.6 ± 48.9 vs 192.3 ± 29.8 mg/dl, p <0.001) and low-density lipoprotein cholesterol (138.7 ± 40.7 vs 123.2 ± 22.9 mg/dl, p <0.0001) levels. Conclusions. In patients with STEMI the presence of remote ST↓ is rather frequent, and seems to indicate a real heterozonal ischemia, independently of an epicardial coronary stenosis of the non-infarct-related artery. Remote ST↓ is associated with a higher incidence of risk factors related to microcirculatory dysfunction, such as cigarette smoking, a worse lipid profile and less protective factors, such as the use of statins prior to acute myocardial infarction

How to Recognize a Creative SME?

Part 1: Knowledge Discovery and SharingInternational audienceIn the actual knowledge-based economy, intangible assets are crucial. Those assets cannot be created without the creativity of the employees. Despite the phenomenal amount of works published on creativity, only a few are related to Small and Medium Enterprises (SME). Furthermore, a literature review made evident that a proper definition of what is a creative SME does not exist, even though it is important for practitioners, researchers and professionals in this domain. A definition of a creative SME needs to include external characteristics, ones that are easy to recognize from an observer’s point of view. This research is thus trying to answer the following question: “How can we recognize a creative SME?” By using a Delphi with a group of experts, the researchers obtained a list of characteristics to recognize a creative SME. A case-study based research on internal factors that affect creative SME characteristics will follow
