Leveraging 3D Technologies for Hardware Security: Opportunities and Challenges
Peng Gu, Shuangchen Li, Dylan Stow +4
3D die stacking and 2.5D interposer design are promising technologies to improve integration density, performance and cost. Current approaches face serious issues in dealing with e…
MPU: Towards Bandwidth-abundant SIMT Processor via Near-bank Computing
Xinfeng Xie, Peng Gu, Yufei Ding +3
With the growing number of data-intensive workloads, GPU, which is the state-of-the-art single-instruction-multiple-thread (SIMT) processor, is hindered by the memory bandwidth wal…
Signature-Kernel Based Evaluation Metrics for Robust Probabilistic and Tail-Event Forecasting
Benjamin R. Redhead, Thomas L. Lee, Peng Gu +2
Probabilistic forecasting is increasingly critical across high-stakes domains, from finance and epidemiology to climate science. However, current evaluation frameworks lack a conse…
Compton Scattering Energy Spectrum for Si and Ge Systems
Chen-Kai Qiao, Hsin-Chang Chi, Shin-Ted Lin +3
In the present work, we study the atomic Compton Scattering which could have great impacts on dark matter direct detection experiments. We give a quantitative analysis of the Compt…
Transient transition from free carrier metallic state to exciton insulating state in GaAs by ultrafast photoexcitation
X. C. Nie, H. Y. Liu, Xiu Zhang +6
We present systematic studies of the transient dynamics of GaAs by ultrafast time-resolved optical reflectivity. In photo excited non-equilibrium states, we found a sign reverse in…
Relativistic Impulse Approximation in Compton Scattering
Chen-Kai Qiao, Hsin-Chang Chi, Lei Zhang +5
Relativistic impulse approximation (RIA) has been widely used in atomic, condensed matter, nuclear, and elementary particle physics. In former treatments of RIA formulation, differ…
Recovery of Saturated Signal Waveforms by Artificial Neural Networks
Yu Liu, Jing-Jun Zhu, Neil Roberts +5
Particle may sometimes have energy outside the range of radiation detection hardware so that the signal is saturated and useful information is lost. We have therefore investigated…
