Abstract:

Characteristics of multi-particle production in proton-proton collisions at √s = 7 TeV are studied as a function of the charged-particle multiplicity, N ch. The produced particles are separated into two classes: those belonging to jets and those belonging to the underlying event. Charged particles are measured with pseudorapidity {pipe}η{pipe}<2.4 and transverse momentum p T>0.25 GeV/c. Jets are reconstructed from charged-particles only and required to have p T>5 GeV/c. The distributions of jet p T, average p T of charged particles belonging to the underlying event or to jets, jet rates, and jet shapes are presented as functions of N ch and compared to the predictions of the pythia and herwig event generators. Predictions without multi-parton interactions fail completely to describe the N ch-dependence observed in the data. For increasing N ch, pythia systematically predicts higher jet rates and harder p T spectra than seen in the data, whereas herwig shows the opposite trends. At the highest multiplicity, the data-model agreement is worse for most observables, indicating the need for further tuning and/or new model ingredients. © 2013 CERN for the benefit of the CMS collaboration.

Abstract:

This paper presents a search for the pair production of top squarks in events with a single isolated electron or muon, jets, large missing transverse momentum, and large transverse mass. The data sample corresponds to an integrated luminosity of 19.5 fb-1 of pp collisions collected in 2012 by the CMS experiment at the LHC at a center-of-mass energy of √s = 8 TeV. No significant excess in data is observed above the expectation from standard model processes. The results are interpreted in the context of supersymmetric models with pair production of top squarks that decay either to a top quark and a neutralino or to a bottom quark and a chargino. For small mass values of the lightest supersymmetric particle, top-squark mass values up to around 650 GeV are excluded. © 2013 CERN for the benefit of the CMS collaboration.

Multicenter retrospective comparative study of laparoscopically assisted and conventional anorectoplasty for male infants with rectoprostatic urethral fistula.

Journal of pediatric surgery 48:12 (2013) 2383-2388

Abstract:

Background

Laparoscopically assisted anorectoplasty (LAARP) was expected to achieve better fecal continence than conventional procedures. However, the issue of which approach is better remains controversial. We compared outcomes between the conventional procedure and LAARP in male infants with rectoprostatic urethral fistula.

Methods

Institutes belonging to the Japanese Study Group of Anorectal Anomalies (JSGA) were invited to participate. Subjects were male infants with rectoprostatic urethral fistula treated by the conventional approach (abdominoperineal pull-through and PSARP) or LAARP between 2000 and 2006. Medical charts and operative records were reviewed retrospectively.

Results

Eighty-one patients (conventional: 36, LAARP: 45) were enrolled from 15 centers. In both groups, the mean Kelly score was 5. The total score of the scoring system was newly developed by the Japanese Study Group of Anorectal Anomalies. Follow-up Project (5-15 points) was 10.7 and 12.1 in the conventional group and the LAARP group, respectively (p=0.07). The incidence of failed rectoanal anastomosis, mucosal prolapse, and anal stenosis was comparable in both groups. Posterior urethral diverticula were detected on cystourethrograms in 7% and 11% (p=1.0) and on MRI in 0% and 34% (p=0.02) of the conventional and the LAARP groups, respectively. Overall, 94% of diverticula were asymptomatic.

Conclusions

Fecal continence and complication rates after LAARP were comparable to those observed after the conventional method. Posterior urethral diverticula were detected more frequently after LAARP.

Abstract:

This paper presents a search for the pair production of top squarks in events with a single isolated electron or muon, jets, large missing transverse momentum, and large transverse mass. The data sample corresponds to an integrated luminosity of 19.5 fb of pp collisions collected in 2012 by the CMS experiment at the LHC at a center-of-mass energy of {Mathematical expression}. No significant excess in data is observed above the expectation from standard model processes. The results are interpreted in the context of supersymmetric models with pair production of top squarks that decay either to a top quark and a neutralino or to a bottom quark and a chargino. For small mass values of the lightest supersymmetric particle, top-squark mass values up to around 650 GeV are excluded. © 2013 CERN for the benefit of the CMS collaboration.
