At 136 pages, the pocket-sized fifth edition of the National Association of Elevator Contractors’ (NAEC) Field Employees’ Elevator Testing Manual is not even a quarter of the length of the American Society of Mechanical Engineers (ASME) A17.2-2020 Guide for Inspection of Elevators, Escalators and Moving Walks.

In December 2024, I had the opportunity to visit the National Elevator Industry Educational Program’s Training Center in Warwick, Rhode Island. As I walked into the area that houses welding booths, I was pleased to see a sticky mat at the entrance to the area. It has been a while since I had seen one of those outside an elevator machine room door, back when motor-generator sets were the norm, and we were all afraid of tracking carbon dust across a customer’s carpeted floors.

Inspired by the BESIII newest observation of X(2370) glueball-like particle, we search its productions in both e+e− collisions at s=4.95  GeV and proton-proton (pp) collisions at s=13  TeV with a parton and hadron cascade model PACIAE. In this model, the final partonic state (FPS) and the final hadronic state (FHS) are consecutively simulated and recorded.
