We report a measurement of the \(\nu_\mu\) charged current quasi-elastic cross-sections on carbon in the T2K on-axis neutrino beam. The measured charged current quasi-elastic cross-sections on carbon ...at mean neutrino energies of 1.94 GeV and 0.93 GeV are \((11.95\pm 0.19(stat.)_{-1.47}^{+1.82} (syst.))\times 10^{-39}\mathrm{cm}^2/\mathrm{neutron}\) and \((10.64\pm 0.37(stat.)_{-1.65}^{+2.03} (syst.))\times 10^{-39}\mathrm{cm}^2/\mathrm{neutron}\), respectively. These results agree well with the predictions of neutrino interaction models. In addition, we investigated the effects of the nuclear model and the multi-nucleon interaction.
We report the first measurement of the neutrino-oxygen neutral-current quasielastic (NCQE) cross section. It is obtained by observing nuclear deexcitation \(\gamma\)-rays which follow neutrino-oxygen ...interactions at the Super-Kamiokande water Cherenkov detector. We use T2K data corresponding to \(3.01 \times 10^{20}\) protons on target. By selecting only events during the T2K beam window and with well-reconstructed vertices in the fiducial volume, the large background rate from natural radioactivity is dramatically reduced. We observe 43 events in the \(4-30\) MeV reconstructed energy window, compared with an expectation of 51.0, which includes an estimated 16.2 background events. The background is primarily nonquasielastic neutral-current interactions and has only 1.2 events from natural radioactivity. The flux-averaged NCQE cross section we measure is \(1.55 \times 10^{-38}\) cm\(^2\) with a 68\% confidence interval of \((1.22, 2.20) \times 10^{-38}\) cm\(^2\) at a median neutrino energy of 630 MeV, compared with the theoretical prediction of \(2.01 \times 10^{-38}\) cm\(^2\).
The T2K experiment has performed a search for \(\nu_e\) disappearance due to sterile neutrinos using \(5.9 \times 10^{20}\) protons on target for a baseline of \(280 m\) in a neutrino beam peaked at ...about \(500 MeV\). A sample of \nu_e CC interactions in the off-axis near detector has been selected with a purity of 63\% and an efficiency of 26\%. The p-value for the null hypothesis is 0.085 and the excluded region at 95\% CL is approximately \(sin^2 2 \theta_{ee} > 0.3\) for \(\Delta m^2_{eff} > 7 eV^2 / c^4\).
We report a measurement of the \(\nu_\mu\) inclusive charged current cross sections on iron and hydrocarbon in the T2K on-axis neutrino beam. The measured inclusive charged current cross sections on ...iron and hydrocarbon averaged over the T2K on-axis flux with a mean neutrino energy of 1.51 GeV are \((1.444\pm0.002(stat.)_{-0.157}^{+0.189}(syst.))\times 10^{-38}\mathrm{cm}^2/\mathrm{nucleon}\), and \((1.379\pm0.009(stat.)_{-0.147}^{+0.178}(syst.))\times 10^{-38}\mathrm{cm}^2/\mathrm{nucleon}\), respectively, and their cross section ratio is \(1.047\pm0.007(stat.)\pm0.035(syst.)\). These results agree well with the predictions of the neutrino interaction model, and thus we checked the correct treatment of the nuclear effect for iron and hydrocarbon targets in the model within the measurement precisions.

Background/Introduction
Patients with myocarditis are at risk for severe, life-threatening arrhythmia. However, predictors to identify ...high-risk patients are lacking.
Purpose
We investigated the occurrence and potential risk factors of severe arrhythmia in myocarditis patients.
Methods
212 myocarditis patients that were hospitalized for arrhythmia monitoring at a tertiary university hospital were retrospectively enrolled. Non-sustained ventricular tachycardia (VT), sustained VT, ventricular fibrillation or cardiac arrest were considered as severe arrhythmia. We used a stepwise logistic regression model to investigate potential predictors. These included age, sex, clinical presentation (chest pain, palpitations, dyspnea, syncope, cardiac murmur, edema, pericardial friction, arrhythmia at presentation, Killip-class), comorbidities (hypertension, diabetes, coronary heart disease), imaging parameters (left ventricular ejection fraction LVEF, pericardial effusion, edema and LGE on MRI), ECG variables (PQ depression, ST elevation, ST depression) and maximum levels of blood biomarkers (CRP, leukocytes, Troponin T, CK-MB).
Results
Mean age was 40.8 years, 73.1% were male and mean LVEF was 52.9%. During the hospital stay, 40 (18.9%) patients experienced severe arrhythmia: 33 (15.6%) non-sustained VT, 9 (4.2%) sustained VT, 1 (0.5%) ventricular fibrillation and 3 (1.4%) cardiac arrests (arrhythmia not mutually exclusive). Most arrhythmia occurred in the first 72h of monitoring (Figure). Significant predictors selected by the stepwise model (OR 95% CI) for severe arrhythmia were LVEF (per 1% increase 0.95 0.92; 0.99, p=0.005), syncope at presentation (7.9 1.5; 40.4, p=0.01), any arrhythmia at first presentation (6.5 1.3; 32.7, p=0.02) and CK-MB (per 10-unit increase 1.2 1.1; 1.3, p=0.001).
Conclusion(s)
Myocarditis patients with low LVEF, presenting with arrhythmia and syncope and with increased CK-MB are at increased risk for severe arrhythmia and should be closely monitored. Further studies are needed to define, if patients without these risk factors might be safely discharged early.
Rationale Digital health interventions have demonstrated positive impacts on clinical outcomes in asthma, but data on their impact in chronic obstructive pulmonary disease (COPD), and among older ...populations, have been limited. To assess feasibility, we evaluated the number of participants that enrolled and synced a sensor to initiate data transmission, and the duration of active participation.

A new species of Goeldia Keyserling, 1891 is described. Goeldia is the only genus of Titanoecidae with species in the Neotropical region and includes eight species diagnosed by the presence of a ...patellar process in the male palp. The new species, Goeldia zyngierae sp. nov., was found living inside the Casa de Pedra cave, Ribeira, Itabaiana, Sergipe, Brazil. Goeldia zyngierae sp. nov. is diagnosed by the tegular process with a small constriction near the base of the dorsal part and by a distal narrowing, more visible in the dorsal side of the patellar process of the male palp. The female epigynum shows a pair of sinuous depressions and a large mid field that does not close the copulatory openings as in Goeldia luteipes Keyserling, 1878. The vulva presents a narrow and straight copulatory duct in comparison with those of Goeldia mexicana Pickard-Cambridge, 1896 and a narrow spermathecae. The description includes illustrations of the genital organs, measurements of the body and legs and leg spination. Notes on the natural history show that inside the cave the spiders live farther than the first 40 m, in the aphotic zone, under stones or on the wall. They were never observed alone or walking on the ground, and the webs contained two to thirty spiders of different life stages, living together, suggesting a possible cooperative behavior. Further field work is needed to confirm and understand the degree of sociability of this new species, if this species is restricted to caves, and if this behavior occurs only inside the caves.
Quantitative inventories of two narrowly-rectangular plots of terra firme Amazonian rainforest were conducted in the habitats of the Arawete and Asurini Indians, respectively The samples included all ...trees with a dbh of $\geq 10$ cm. Relative density, frequency, and dominance are presented for the 20 most important tree species on each plot; species and family importance values are also presented. The Arawete plot had 441 individuals, 142 species, and a total basal area of 22.10 m$^2$; the Asurini plot had 464 individuals, 137 species, and a basal area of 21.90 m$^2$ The data suggest that both plots are parcels of a single forest type that conforms to the criteria for Amazonian liana forest. Many of the species on the plots, such as Orbignya phalerata. Theobroma speciosum, Maximiliana maripa and Bertholletia excelsa, are disturbance indicators in the eastern Amazon. This, and the presence near both sites of Indian black earth (terra preta do indio), suggest that much of these forests may have been felled and burned for shifting cultivation at least once in the past.
In this study we describe three new litter inhabiting species of Mesabolivar González-Sponga, 1998 from nine urban forest remnants in the metropolitan region of the city of São Paulo, Brazil: M. ...forceps, M. mairyara and M. cavicelatus. In three of these remnants, we conduced a three year sampling using pitfall traps. Mesabolivar forceps sp. nov. was the most abundant pholcid (n=273 adults), always present in the samples, but with highest numbers in spring and summer. Mesabolivar mairyara sp. nov. was the second most abundant species (n=32), but the majority of individuals were collected in March 2001. Only three individuals of M. cavicelatus sp. nov. were collected.
