An overview of measurements of the Higgs boson production cross sections and couplings performed by the CMS collaboration is presented. Focus is put on measurements that target bosonic decays of the Higgs boson and exploit the data set collected during Run 2 of the CERN LHC. Measurements in the WW, ZZ, and diphoton decay channels are covered, as well as a measurement targeting the production of the Higgs boson in association with t quarks, which includes decays to WW, ZZ, and 𝜏𝜏. Results are presented in the form of cross sections and coupling strengths normalized to their theoretical expectations (modifiers), as well as simplified template cross sections.

With the ever growing amount of data collected by the ATLAS and CMS experiments at the CERN LHC, fiducial and differential measurements of the Higgs boson production cross section have become important tools to test the standard model predictions with an unprecedented level of precision, as well as seeking deviations that can manifest the presence of physics beyond the standard model. These measurements are in general designed for being easily comparable to any present or future theoretical prediction, and to achieve this goal it is important to keep the model dependence to a minimum. Nevertheless, the reduction of the model dependence usually comes at the expense of the measurement precision, preventing to exploit the full potential of the signal extraction procedure. In this paper a novel methodology based on the machine learning concept of domain adaptation is proposed, which allows using a complex deep neural network in the signal extraction procedure while ensuring a minimal dependence of the measurements on the theoretical modelling of the signal.

The starting point of an orthodontic treatment is represented by a complete and a correct diagnosis. Therefore the Authors investigated the need of a soft tissue analysis that is related to the University of Connecticut cephalometric analysis. The authors emphasize the importance of the vertical, horizontal and angular index in some patients with values different from the normal values. The soft tissue and esthetic data allow to finalize the orthodontic treatment to the esthetic improvement (besides occlusal) for the patients needs.

Recent differential cross section measurements in the Higgs sector published by the ATLAS and CMS collaborations are presented, exploiting the full data set from Run 2 of the LHC.Results cover an extensive set of observables, production modes and final states.In particular, the measurements that are presented include Higgs boson decays to a pair of W or Z bosons, a pair of photons, a pair of leptons and a pair of b quarks.All results are found to be in good agreement with the Standard Model of particle physics.

The correction of dental rotation associated with a lingual or buccal version is possible to obtain with the action of a force system that is: consistent or inconsistent. The authors investigated a mandibular right second bicuspid rotated positively with its distal surface to the buccal. They decided to correct this rotation by using a consistent force system formed by a force and a moment applied to center of resistance (long axis in the occlusal view) and in lingual direction. It's possible to obtain in a consistent force system with the utilization of a straight wire or a "cantilever beam". The Authors decided to correct this rotation by using a cantilever beam of 017x025 wire with a vertical loop hooked over a heavier 021x025 wire between the first and the second molars. With an inconsistent system it's necessary to include a box loop so it is possible to make a variation and insert the wire from teh anterior or posterior just to obtain a consistent force system.
