The production of ϒ(2S) and ϒ(3S) mesons in lead-lead (Pb-Pb) and proton-proton (pp) collisions is studied in their dimuon decay channel using the CMS detector at the LHC. The ϒ(3S) meson is observed for the first time in Pb-Pb collisions, with a significance above 5 standard deviations. The ratios of yields measured in Pb-Pb and pp collisions are reported for both the ϒ(2S) and ϒ(3S) mesons, as functions of transverse momentum and Pb-Pb collision centrality.

Article Synopsis
  • The study evaluates the effectiveness of different classification criteria for systemic lupus erythematosus (SLE) in a cohort of children in Singapore, noting that clinical manifestations can vary in this population.
  • Among the criteria tested, SLICC-2012 had the highest sensitivity (ability to correctly identify cases) at initial diagnosis, while ACR-1997 showed the highest specificity (ability to correctly identify non-cases).
  • The findings highlight that using a cutoff score of 13 for the EULAR/ACR-2019 criteria can enhance diagnostic accuracy, and overall, all criteria demonstrated over 85% diagnostic accuracy both at diagnosis and over time.

Robotics is entering our daily lives. The discipline is increasingly crucial in fields such as agriculture, medicine, and rescue operations, impacting our food, health, and planet. At the same time, it is becoming evident that robotic research must embrace and reflect the diversity of human society to address these broad challenges effectively.

Article Synopsis
  • The study aimed to compare the outcomes of two different weaning strategies (short vs. long) for anti-tumor necrosis factor (aTNF) in patients with juvenile idiopathic arthritis (JIA) after achieving clinical remission.
  • A total of 110 JIA patients were involved, with no significant differences found in flare rates or time to flare between the two weaning methods, despite variations in other risk factors like positive anti-nuclear antibodies and HLA-B27 status.
  • The findings suggest that the duration of weaning aTNF does not significantly affect flare rates or delay flares, but many patients who experienced flares still had high rates of inactive disease at the six-month mark following weaning.

Quasireal photons exchanged in relativistic heavy ion interactions are powerful probes of the gluonic structure of nuclei. The coherent J/ψ photoproduction cross section in ultraperipheral lead-lead collisions is measured as a function of photon-nucleus center-of-mass energies per nucleon (W_{γN}^{Pb}) over a wide range of 40 View Article and Find Full Text PDF

Background: Colonic diverticular disease is common and its incidence increases with age, with uncomplicated diverticulitis being the most common acute presentation (1). This typically results in inpatient admission, placing a significant burden on healthcare services (2). We aimed to determine the safety and effectiveness of using intravenous or oral antibiotics in the treatment of uncomplicated diverticulitis on 30-day unplanned admissions, c-reactive protein (CRP), White Cell Count (WCC), pain resolution, cessation of pain medication, return to normal nutrition, and return to normal bowel function.

  • - The study investigates how the ratio of production fractions of B_{s}^{0} and B^{+} hadrons (f_{s}/f_{u}) varies with the transverse momentum (p_{T}) and rapidity of B mesons using data from proton-proton collisions at 13 TeV collected by the CMS experiment in 2018.

The structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, and polarization of the constituent partons. Such a structure can be studied using high-energy photons produced in ultraperipheral heavy-ion collisions. The first measurement of the azimuthal angular correlations of exclusively produced events with two jets in photon-lead interactions at large momentum transfer is presented, a process that is considered to be sensitive to the underlying nuclear gluon polarization.
