Dose rate effects in the radiation damage of the plastic scintillators of the CMS hadron endcap calorimeter
(Iop Publishing Ltd, 2016)We present measurements of the reduction of light output by plastic scintillators irradiated in the CMS detector during the 8 TeV run of the Large Hadron Collider and show that they indicate a strong dose rate effect. The ... -
ECG feature extraction based on the bandwidth properties of variational mode decomposition
(Iop Publishing Ltd, 2016)It is a difficult process to detect abnormal heart beats, known as arrhythmia, in long-term ECG recording. Thus, computer-aided diagnosis systems have become a supportive tool for helping physicians improve the diagnostic ... -
An embedding technique to determine tau tau backgrounds in proton-proton collision data
(Iop Publishing Ltd, 2019)An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau ... -
Experimental study of different silicon sensor options for the upgrade of the CMS Outer Tracker
