Search for MSSM Higgs bosons decaying to μ+μ-in proton-proton collisions at √s=13TeV

A search is performed for neutral non-standard-model Higgs bosons decaying to two muons in the context of the minimal supersymmetric standard model (MSSM). Proton-proton collision data recorded by the CMS experiment at the CERN Large Hadron Collider at a center-of-mass energy of 13TeVwere used, corresponding to an integrated luminosity of 35.9fb-1. The search is sensitive to neutral Higgs bosons produced via the gluon fusion process or in association with a bbquark pair. No significant deviations from the standard model expectation are observed. Upper limits at 95% confidence level are set in the context of the mmod+hand phenomenological MSSM scenarios on the parameter tanβas a function of the mass of the pseudoscalar Aboson, in the range from 130 to 600GeV. The results are also used to set a model-independent limit on the product of the branching fraction for the decay into a muon pair and the cross section for the production of a scalar neutral boson, either via gluon fusion, or in association with bquarks, in the mass range from 130 to 1000GeV

Studies of charm and beauty hadron long-range correlations in pp and pPb collisions at LHC energies

Measurements of the second Fourier harmonic coefficient (v(2)) of the azimuthal distributions of prompt and nonprompt D-0 mesons produced in pp and pPb collisions are presented. Nonprompt D-0 mesons come from beauty hadron decays. The data samples are collected by the CMS experiment at nucleon-nucleon center-of-mass energies of 13 and 8.16 TeV, respectively. In high multiplicity pp collisions, v(2) signals for prompt charm hadrons are reported for the first time, and are found to be comparable to those for light-flavor hadron species over a transverse momentum (pT) range of 2-6 GeV. Compared at similar event multiplicities, the prompt D-0 meson v(2) values in pp and pPb collisions are similar in magnitude. The v(2) values for open beauty hadrons are extracted for the first time via nonprompt D-0 mesons in pPb collisions. For pT in the range of 2-5 GeV, the results suggest that v(2) for nonprompt D-0 mesons is smaller than that for prompt D-0 mesons. These new measurements indicate a positive charm hadron v(2) in pp collisions and suggest a mass dependence in v(2) between charm and beauty hadrons in the pPb system. These results provide insights into the origin of heavy-flavor quark collectivity in small systems. (C) 2020 The Author(s). Published by Elsevier B.V.Peer reviewe

Digitale geletterdheid bij Vlaamse jongeren: hoe gaan ze om met onlinecontentrisico's?

Contains fulltext : 90156-OA.pdf (publisher's version ) (Open Access)We onderzoeken welke onlinerisico’s Vlaamse jongeren (15-19) lopen. We stellen vast dat een hoge mate van digitale geletterdheid samengaat met een hoge blootstelling aan internetrisico’s. Jongeren met veel zelfvertrouwen komen vaker in contact met risicovolle online-inhoud. Een goede vertrouwensband met de ouders vermindert de kans op risicovolle blootstelling. Jongeren ondernemen weinig actie na een negatieve online-ervaring

PTNS: a new treatment option for lower urinary tract dysfunction.

Contains fulltext : 51953.pdf (publisher's version ) (Open Access)Nearly one out of two Dutch married women experiences urine loss. Overactivity of the bladder can cause urine loss and frequent micturition. At the urology department of the UMC Nijmegen, Posterior Tibial Nerve Stimulation or PTNS to treat overactive bladder complaints was investigated. Also patients with voiding dysfunction were examined. 90 patients with overactive bladder complaints and 39 patients with voiding dysfunction were enrolled in the study. All patients received 12 weekly sessions in which a needle was placed three fingerbreadths above the medial ankle and connected to a low voltage stimulator for 30 minutes. 60-64% of the participants considered the treatment as successful and demanded maintenance therapy. Patients presented with less urine loss and less urinary frequency. 38% was even considered as continent. Urodynamic investigation confirmed increment of bladder capacity, a larger volume at which desire to void appears and more efficient bladder emptying. Quality of life parameters improved. No mayor side effects were seen. PTNS is minimally invasive treatment without serious side effects. Unfortunately a long term maintenance schedule is needed; therefore more investigation concerning the implantable stimulator is warrantedRU Radboud Universiteit Nijmegen, 17 september 2007Promotores : Bemelmans, B.L.H., Debruyne, F.M.J.

Digital literacy of Flemish youth: How do they handle online content risks?

Contains fulltext : 90153-OA.pdf (publisher's version ) (Open Access)The internet offers adolescents a huge window of opportunities, but these opportunities are not always exempt from risks. Indeed, many young people are nowadays confronted with spam, gruesome or violent images and content including pornography, drugs, racism, and even suicide. We surveyed 815 Flemish 15- to 19-year-olds about the online risks they (may) have been confronted with and on how they cope with these risks. We controlled for digital literacy levels, socio-demographics and personality traits. Interestingly, our research shows that not only adolescents with a high level of internet literacy but also those with lower internet literacy levels, such as youths enrolled in vocational education, tend to be more frequently exposed to online risks. Also worthwhile noting is the fact that a high level of self-confidence positively correlates with exposure to risky online content. In general, adolescents do not consult anybody when it comes to coping with risks and negative experiences online. However, a good parent-child relationship pays off as kids with a good parental relationship encounter aggressive, sexual or value-based content less frequently

Posterior tibial nerve stimulation as neuromodulative treatment of lower urinary tract dysfunction.

Item does not contain fulltextPURPOSE: Recently, intermittent percutaneous posterior tibial nerve stimulation was introduced as a treatment modality filling the gap between conservative and surgical therapies in patients with certain types of lower urinary tract dysfunction. MATERIALS AND METHODS: In a prospective multicenter trial posterior tibial nerve stimulation was evaluated in 37 patients who presented with symptoms of bladder overactivity, that is the urgency and frequency syndrome and/or urge incontinence, and 12 with nonobstructive urinary retention. Results were recorded in voiding diaries and on quality of life questionnaires before and after treatment. Patients were classified as responders, including those in whom therapy was successful and chose to continue treatment after the initial 12 weeks, and nonresponders, those who chose to stop treatment. RESULTS: Overall, a positive response was seen in 60% of all patients. In patients with bladder overactivity a statistically significant decrease was observed in leakage episodes, number of pads used, voiding frequency and nocturia, and an equal increase in mean and smallest volume voided. Improvements were also seen in nonobstructive urinary retention, including number of catheterizations, total and mean volume catheterized, and total and mean volume voided. Disease specific quality of life and some domains of general quality of life improved, especially of bladder overactivity. Only mild side effects were observed. CONCLUSIONS: Posterior tibial nerve stimulation is a minimally invasive and successful treatment option for patients with certain types of lower urinary tract dysfunction
