The extinction model studied in this analysis is motivated by the search for signatures of strong gravity at the TeV scale (terascale gravity) and assumes the existence of string couplings in the strong-coupling limit. In this limit, the string model predicts the suppression of all high-transverse-momentum standard model processes, including jet production, beyond a certain energy scale. To test this prediction, the measured transverse-momentum spectrum is compared to the theoretical prediction of the standard model. No significant deficit of events is found at high transverse momentum. A 95% confidence level lower limit of 3.3 TeV is set on the extinction mass scale

Searches for electroweak neutralino and chargino production in channels with Higgs, Z, and W bosons in pp collisions at 8 TeV

Searches for supersymmetry (SUSY) are presented based on the electroweak pair production of neutralinos and charginos, leading to decay channels with Higgs, Z, and W bosons and undetected lightest SUSY particles (LSPs). The data sample corresponds to an integrated luminosity of about 19.5 fb(-1) of proton-proton collisions at a center-of-mass energy of 8 TeV collected in 2012 with the CMS detector at the LHC. The main emphasis is neutralino pair production in which each neutralino decays either to a Higgs boson (h) and an LSP or to a Z boson and an LSP, leading to hh, hZ, and ZZ states with missing transverse energy (E-T(miss)). A second aspect is chargino-neutralino pair production, leading to hW states with E-T(miss). The decays of a Higgs boson to a bottom-quark pair, to a photon pair, and to final states with leptons are considered in conjunction with hadronic and leptonic decay modes of the Z and W bosons. No evidence is found for supersymmetric particles, and 95% confidence level upper limits are evaluated for the respective pair production cross sections and for neutralino and chargino mass values

OCULAR SURFACE CHANGES INDUCED BY TOPICAL APPLICATION OF LATANOPROST AND TIMOLOL: THE ROLE OF BENZALKONIUM CHLORIDE CONCENTRATION THRUGHOUT A SHORT-TERM STUDY IN GLAUCOMATOUS PATIENTS WITH AND WITHOUT ALLERGIC CONJUNCTIVITIS

BACKGROUND: This study evaluated the conjunctival effects of latanoprost and timolol, both of which contain benzalkonium chloride, in patients with primary open-angle glaucoma (POAG), with and without a history of allergic conjunctivitis (AC). METHODS: Two groups of 25 patients with and without a positive history for AC were studied. After a 21-day wash-out period patients were randomized to 14 days treatment with latanoprost or with timolol, in a cross-over fashion. The following parameters were evaluated on days 0 and 14: number of white blood cells, ferning test, conjunctival impression cytology, subjective symptoms, and objective ocular changes. RESULTS: Latanoprost caused: (a) an increase in eosinophils in both groups and reduction in lymphocytes only in the group with a history of AC; (b) alterations in ferning test and impression cytology only in AC patients; and (c) development of subjective symptoms and objective signs only in non-AC glaucomatous subjects. Timolol therapy was responsible only for the occurrence of subjective symptoms and objective signs in non-AC patients. CONCLUSION: Latanoprost treatment induces ocular surface changes which are more evident in POAG patients who are also affected by AC. These findings are probably related to the very high latanoprost concentration of benzalkonium chloride and to its bedtime administration, which further amplifies the toxicity

A.I.N.O.S.Raccomandazioni sul trattamento del paziente odontoiatrico in terapia anticoagulante

L'odontoiatria moderna riunisce una diversità di interventi chirurgici che vengono eseguiti in modo crescente in regime ambulatoriale. In passato, il paziente in trattamento con antivitaminici K per via orale (AVK) doveva essere ospedalizzato per 3-5 giorni nel corso dei quali l'assunzione di AVK veniva sospesa e sostituita con eparina somministrata per via e.v. Questa procedura non risponde più oltre a criteri di attualità grazie alla scoperta delle eparine a basso peso molecolare (EBPM) (Low Molecular Weight Heparin = LMWH) le quali possono sostituire l'assunzione degli AVK ottenendo il passaggio dalla via di somministrazione per via gastrointestinale (AVK) alla via di somministrazione per via sottocutanea (EBPM) mentre il paziente si trova ancora a domicilio.Da questa sede il paziente può essere direttamente trasferito nella struttura ambulatoriale per essere sottoposto all'intervento in precedenza programmato. L'intera procedura deve essere obbligatoriamente preceduta da una consultazione preanestesica a distanza e da un buon coordinamento interdisciplinare e di quello del personale assistente preposto

A.I.N.O.S.Raccomandazioni sulle caratteristiche dell'ambulatorio odontoiatrico in relazione alla erogazione di interventi di anestesiaodontostomatologica effettuati in ansiolisi

L'ambulatorio odontoiatrico, anche in accordo con le indicazioni tuttora vigenti del General Dental Council, dell'European Federation for the Advancement of Anestesia in Dentistry e dell'American Dentai Association, relativamente alle prestazioni di anestesia odontostomatologica effettuate in ansiolisi, deve essere costituito dai seguenti locali: Sala della visita preoperatoria; Sala d'attesa; Sala chirurgica; Sala operatoria; Sala di risveglio. Sono escluse da questo elenco le altre sale per personale ausiliario, deposito medicinali, etc

Recent results and performance of the multi-gap resistive plate chambers network for the EEE Project

The Extreme Energy Events (EEE) Project is devoted to the study of Extensive Atmospheric Showers through a network of muon telescopes, installed in High Schools, with the further aim of introducing young students to particle and astroparticle physics. Each telescope is a tracking detector composed of three Multi-gap Resistive Plate Chambers (MRPC) with an active area of 1.60 × 0.80 m(2). Their characteristics are similar to the ones built for the Time Of Flight array of the ALICE Experimentat LHC . The EEE Project started with a few pilot towns, where the telescopes have been taking data since 2008, and it has been constantly extended, reaching at present more than 50 MRPCs telescopes. They are spread across Italy with two additional stations at CERN, covering an area of around 3 × 10(5) km(2), with a total surface area for all the MRPCs of 190 m(2). A comprehensive description of the MRPCs network is reported here: efficiency, time and spatial resolution measured using cosmic rays hitting the telescopes. The most recent results on the detector and physics performance from a series of coordinated data acquisition periods are also presented

Advanced Virgo Status

International audienceThe Advanced Virgo project was funded in 2009 with the aim of improving the sensitivity of the Virgo interferometric detector for gravitational waves by a factor of ten, which corresponds to an increase in the detection rate by about three orders of magnitude. The upgrade is now close to completion: the new interferometer will enter its commissioning phase in 2016. The new detector will be hosted in the same infrastructure as Virgo, but many technological upgrades have been put in place to reach the sensitivity goal. In this paper the detector design and the observational perspectives are discussed
