Pileup mitigation at CMS in 13 TeV data
(IOP Publishing, 2020-09)With increasing instantaneous luminosity at the LHC come additional reconstruction challenges. At high luminosity, many collisions occur simultaneously within one proton-proton bunch crossing. The isolation of an interesting ... -
Porous materials
(Elsevier, 2018)Natural gas has received significant attention as a cleaner energy source alternative to gasoline. Natural gas consists of mainly methane (CH4); therefore, efficient storage of CH4 is essential to utilize natural gas. ... -
