Search for the standard model Higgs boson decaying to a bb pair in events with one charged lepton and large missing transverse energy using the full CDF data set

We present a search for the standard model Higgs boson produced in association with a W boson in sqrt(s) = 1.96 TeV p-pbar collision data collected with the CDF II detector at the Tevatron corresponding to an integrated luminosity of 9.45 fb-1. In events consistent with the decay of the Higgs boson to a bottom-quark pair and the W boson to an electron or muon and a neutrino, we set 95% credibility level upper limits on the WH production cross section times the H->bb branching ratio as a function of Higgs boson mass. At a Higgs boson mass of 125 GeV/c2 we observe (expect) a limit of 4.9 (2.8) times the standard model value.Comment: Submitted to Phys. Rev. Lett (v2 contains clarifications suggested by PRL

Search for the standard model Higgs boson decaying to a bbˉb\bar{b} pair in events with no charged leptons and large missing transverse energy using the full CDF data set

We report on a search for the standard model Higgs boson produced in association with a vector boson in the full data set of proton-antiproton collisions at $\sqrt{s} = 1.96$ TeV recorded by the CDF II detector at the Tevatron, corresponding to an integrated luminosity of 9.45 fb$^{-1}$. We consider events having no identified charged lepton, a transverse energy imbalance, and two or three jets, of which at least one is consistent with originating from the decay of a $b$ quark. We place 95% credibility level upper limits on the production cross section times standard model branching fraction for several mass hypotheses between 90 and $150 \mathrm{GeV}/c^2$. For a Higgs boson mass of $125 \mathrm{GeV}/c^2$, the observed (expected) limit is 6.7 (3.6) times the standard model prediction.Comment: Accepted by Phys. Rev. Let

Search for the standard model Higgs boson decaying to a bb pair in events with two oppositely-charged leptons using the full CDF data set

We present a search for the standard model Higgs boson produced in association with a Z boson in data collected with the CDF II detector at the Tevatron, corresponding to an integrated luminosity of 9.45/fb. In events consistent with the decay of the Higgs boson to a bottom-quark pair and the Z boson to electron or muon pairs, we set 95% credibility level upper limits on the ZH production cross section times the H -> bb branching ratio as a function of Higgs boson mass. At a Higgs boson mass of 125 GeV/c^2 we observe (expect) a limit of 7.1 (3.9) times the standard model value.Comment: To be submitted to Phys. Rev. Let

Measurement of the difference of CP-violating asymmetries in D0 -> K+K- and D0 ->pi+pi- decays at CDF

We report a measurement of the difference (Delta Acp) between time-integrated CP--violating asymmetries in D0-> K+ K- and D0-> pi+pi- decays reconstructed in the full data set of proton-antiproton collisions collected by the Collider Detector at Fermilab, corresponding to 9.7 fb-1 of integrated luminosity. The strong decay D*+->D0 pi+ is used to identify the charm meson at production as D0 or anti-D0. We measure Delta Acp = [-0.62 +- 0.21 (stat) +- 0.10 (syst)] %, which differs from zero by 2.7 Gaussian standard deviations.This result supports similar evidence for CP violation in charm-quark decays obtained in proton-proton collisions.Comment: Phys. Rev. Lett. 109, 111801 (2012

Indagine su presenza e diffusione dei giallumi della vite in Abruzzo. Atti Giornate Fitopatologiche

The results of the survey carried out in 2018 and 2019 on grapevine yellows diseases (\u201cflavescence dore\ue9\u201d - FD and \u201cbois noir\u201d - BN) in Abruzzo Region (Central Italy) are reported. The monitoring (done according to the European Commission Regulation 652/2014) was carried out in more than 200 vineyards. Symptomatic grapevines were detected with visual inspections from late July to mid-September and the presence of phytoplasmas on symptomatic leaves and canes was detected with molecular analyses. The presence of the main insect vectors, Scaphoideus titanus and Hyalesthes obsoletus, was monitored from the end of June to mid-September using yellow sticky traps. The results showed a widespread presence of BN particularly in the provinces of Chieti and Pescara, while FD was not detected. H. obsoletus was found both on bindweed and nettle present at the borders of the vineyards, while the captures of S. titanus were influenced by the phytosanitary management of the vineyards and by the presence of wild grapevines in the surrounding areas. The results were used for the management of the risk and spread of grapevine yellows disease in the Abruzzo Region

Fattori che influenzano i vettori di Xylella fastidiosa

Xylella fastidiosa sottospecie pauca, batterio gram-negativo agente del “Complesso del disseccamento rapido dell’olivo” (CoDiRO) è ad oggi presente nella parte peninsulare della Puglia e trasmesso principalmente da almeno Philaenus spumarius (Linnaeus), ed in misura minore da Philaenus italosignus (Drosopoulos & Remane) e Neophilaenus campestris (Fallén). L'Abruzzo è zona indenne dalla malattia ma, essendo considerata area a rischio, l'Ufficio Tutela Fitosanitaria della regione ha predisposto un piano di indagini sui vettori (accertati e potenziali) di X. fastidiosa. L’attività di monitoraggio, avviata nel 2016, è stata condotta tramite l’ausilio di trappole cromotropiche nei principali areali olivicoli abruzzesi. P. spumarius è la cicalina maggiormente presente nel territorio, le sue catture non sono risultate influenzate né dalla posizione della trappola nell’oliveto, né dalle attività gestionali degli appezzamenti (lavorazioni del cotico e trattamenti fitosanitari). A livello di paesaggio, alte concentrazioni di oliveto attorno ai siti di monitoraggio favoriscono la presenza e l’abbondanza di P. spumarius all’interno dello stesso, mentre vigneti, bosco e seminativi ne contrastano lo sviluppo. Da analisi fenologiche, la schiusa delle uova comincia mediamente ai primi di marzo e si protrae fino ai primi di aprile, con i giovani che impiegano circa 10gg per completare ognuno dei 5 stadi di sviluppo. Da questi dati si ritiene che il periodo compreso tra la fine di marzo e la fine di aprile sia quello ottimale per permettere il massimo abbattimento delle popolazioni tramite lavorazione del terreno o sfalcio dell’inerbimento negli oliveti. In questa finestra temporale è possibile infatti intercettare potenzialmente l’intera popolazione della cicalina presente come stadio larvale, maggiormente suscettibile al trattamento. La comparsa dei primi adulti è stata osservata verso la fine di aprile, con un picco di catture in maggio ed uno meno marcato in autunno coincidente con il ritorno a terra delle femmine per l’ovideposizione. Le analisi genetiche effettuate sui vettori confermano l’attuale assenza del batterio nella regione Abruzz

NIV feasibility during PEG tube placement in bulbar ALS patients: our experience

Background: Percutaneous Endoscopic Gastrostomy (PEG) is the most widely used procedure for feeding dysphagia in ALS patients with respiratory muscle impairment (RMI). Several studies show that it improves survival. NIV may reduce respiratory complications in ALS patients with forced vital capacity (FVC) less than 50% predicted. Moreover, patients and caregiver\u2019s psychological well-being could decline and some distressing symptoms could occur. Aim: We report our experience of PEG tube placement (PEGTP) with NIV in patients with ALS.Methods: This prospective study was performed between December 2012 and September 2014 in our HD Respiratory Rehabilitation Unit. Data was also retrieved through validated questionnaires considering the following psychological factors: anxiety, depression and Quality of Life. PEGTP was performed during pressure-support/assist-control mode NIV through a nasal mask (nNIV) by a Respiratory Therapist (RT). Mechanical Insufflation-Exsufflation (MI-E) was applied before PEGTP if needed. The RT performed trainings before the PEGTP, with nNIV in patients who were not ventilated at home and who were already ventilated via oronasal mask; The effectiveness of nNIV was checked through patient subjective tolerance, for example, through clinical and gasometric response. In the Endoscopy Unit, sedoanalgesia with midazolam was initiated and biological variables (SpO2, heart rate, respiratory rate, and blood pressure) were monitored continuously.Results:nNIV training required a mean of 3.56 days. Two patients (8%) presented a desaturation during PEGTP. After two months of PEGTP, one patient (4%) died. Conclusions:Our results support the mandatory use of NIV during PEGTP in ALS bulbar onset patients and RMI, and it is associated with minimal peri and post-procedural complications. Therefore, we can conclude that PEGTP in patients with ALS and RMI is safe for the management of NIV and MI-E before PEGTP,with RT support

Is continuous positive airway pressure (CPAP) a new standard of care for type 1 respiratory failure in COVID-19 patients? A retrospective observational study of a dedicated COVID-19 CPAP service

The aim of this case series is to describe and evaluate our experience of continuous positive airway pressure (CPAP) to treat type 1 respiratory failure in patients with COVID-19. CPAP was delivered in negative pressure rooms in the newly repurposed infectious disease unit. We report a cohort of 24 patients with type 1 respiratory failure and COVID-19 admitted to the Royal Liverpool Hospital between 1 April and 30 April 2020. Overall, our results were positive; we were able to safely administer CPAP outside the walls of a critical care or high dependency unit environment and over half of patients (58%) avoided mechanical ventilation and a total of 19 out of 24 (79%) have survived and been discharged from our care

Nam Mang 3 Dam and Evolution of Water management and Land use in the Nam Nyam Valley

The Lao Government emphasizes on economic development to exit from the list of the Least Developed Countries by 2020. Endowed with abundant water resources, the potential of the country for hydropower is huge and the revenue may finance the poverty reduction policy. However, this approach is widely debated for its environmental and socio‐economic impact. The current research focuses on the impact downstream of a dam, using as a case study in the Vientiane plain. Construction of hydropower dams around the Vientiane plain contributed to modifying the livelihood of the 14 500 people from 12 villages living in the Nam Nyam valley. Hydropower operations notably changed the flood flow in rainy season and have affected paddy fields; it increased the flood flow in the 1980s following the construction of the first dam (Nam Ngum1) and reduced in the 2000s when a new dam (Nam Mang3) was built. Although the Government attempted to prevent the negative impacts of Nam Mang 3 dam by funding an irrigated scheme in the Nam Nyam valley, few hundred people that gained access to the new infrastructure were not those people impacted directly by the change of flood flow. This study shows how the Nam Mang 3 dam contributed to the changes of land use in the Vientiane plain, as well as to the socio‐economic differentiation between villagers
