Search for Soft Unclustered Energy Patterns in Proton-Proton Collisions at 13 TeV.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

Evaluation of the use of different intraoral scanners for auricular prosthetic reconstruction.

Statement Of Problem: The use of intraoral optical scanners has been introduced for direct digital data acquisition in maxillofacial prosthetics, but their clinical accuracy has not been evaluated sufficiently.

Purpose: The purpose of this observational study was to evaluate the use of different intraoral scanners for extraoral maxillofacial digitization of an ear and to assess visually the clinical outcome of the generated 3-dimensional ear casts.

Material And Methods: A selected intact ear was scanned by using 3 different intraoral optical scanners: CEREC Primescan (Dentsply Sirona), Medit i700 (Medit Corp) and Panda P2 (Pengtum Technologies).

Search for the Z Boson Decay to ττμμ in Proton-Proton Collisions at sqrt[s]=13 TeV.

The first search for the Z boson decay to ττμμ at the CERN LHC is presented, based on data collected by the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 138  fb^{-1}. The data are compatible with the predicted background. For the first time, an upper limit at the 95% confidence level of 6.

Chlorine-Induced Lung Injury From Hot Tub Exposure.

Chlorine, a dense and irritating gas used in pool disinfection, can cause severe respiratory issues, including airway damage, alveolar injury, pulmonary edema, and chronic conditions such as bronchiolitis obliterans. This case study describes a patient initially thought to have hot tub lung (HTL) due to symptoms, hot tub use, and imaging findings. However, negative Mycobacterium tests and significant chlorine exposure led to a revised diagnosis of chlorine-induced lung injury.
