A constant-fraction discrimination (CFD) system has been combined with a boxcar integrator for detection in inductively coupled plasma/time-of-flight mass spectrometry. The discriminator provides gating logic for the boxcar integrator when an incoming ion signal occurs, but discriminates against electroni...

When magnetic fields partially penetrate a type II superconductor, they do it in specific regions. These regions of penetration are called **flux tubes**. The number of flux tubes per unit area is proportional to the magnetic field with a constant of proportionality equal to the **magnetic flu...
We present a physics-based training simulator for bone machining. Based on experimental studies, the energy required to remove a unit volume of bone is a constant for every particular bone material. We use this physical principle to obtain the forces required to remove bone material with a milli...
The ratio of the number of such events in the two triggered sets of data are used as weight factors. For example, the region above which the track trigger with a pT threshold of 12 GeV/c has constant efficiency is determined by comparing the pT distri- bution of the leading tracks to ...
