Estimation of HRV and SpO2 from wrist-worn commercial sensors for clinical settings by Jarchi, D, Salvi, D, Velardo, C, Mandi, A, Tarassenko, L, Clifton, DA

“…Synchronised PPG signals from the Wavelet Health, the Huawei watch, and the PC-68B were recorded for approximately 10 minutes. …”

Reading between the dies: cross-SLR covert channels on multi-tenant cloud FPGAs by Giechaskiel, I, Rasmussen, K, Szefer, J

“…The cross-SLR covert channel is characterized analytically and experimentally on five Xilinx Virtex UltraScale+ FPGAs, both locally and on the Amazon and Huawei clouds. Several configurations of the source transmitters and the sink receivers are tested, including their locations, types, and sizes. …”

Measuring long wire leakage with ring oscillators in cloud FPGAs by Giechaskiel, I, Rasmussen, K, Szefer, J

“…We experimentally measure the long wire leakage of Virtex UltraScale+ FPGAs in the lab as well as in the Amazon and Huawei FPGA clouds. We show that the two new ring oscillator designs provide almost-identical estimates for the strength of the leakage as traditional ring oscillators, allowing us to measure femtosecond-scale changes in the delays of the long wires. …”
