A Nonuniform-Sampling Theory for Static Multi-Threshold Sampling
Ao Qiu, Qingguo Xie
Multi-Threshold (MT) sampling fixes voltage levels and records when a waveform crosses them. The resulting signal-generated event stream is governed not by a prescribed clock but b…

A Unified Analytical Framework for LYSO-SiPM Scintillation Pulse Dynamics
Ao Qiu, Qingguo Xie
Existing scintillation-detector models typically treat scintillation kinetics, optical transport, silicon photomultiplier (SiPM) response, and timing statistics separately, limitin…

Prior-Based Multi-Voltage Threshold Sampling as a Structured Inverse Problem
Ao Qiu, Qingguo Xie
Prior-based Multi-Voltage Threshold (MVT) sampling reconstructs pulse parameters from sparse threshold-crossing times rather than full waveforms, making parameter recovery inherent…
