Current-dipole detection of microscale metal defects
Eikichi Kimura, Eisuke Oba, Yu Saito +6
An effective electric current dipole provides a compact description of localized current disturbances and has been employed across a broad range of physical systems and length scal…
Universal scaling of electrochemical information transfer at solid-liquid interfaces
Eikichi Kimura, Ashutosh Rathi, Saki Tsuchiya +6
Electrochemical potentials at solid-liquid interfaces govern diverse chemical and energy conversion processes; however, the extent to which their electrochemical influence extends…
Fisher Glasses: Tail-Certified Quantum Metrology in Quenched Environments
El Mustapha Mansouri, Keigo Arai
Quantum metrological advantage is certified by averaged Fisher responses: contrast, susceptibility, or quantum Fisher information (QFI). This fails in quenched sensors, where slow…
Deployment-complete benchmarking
El Mustapha Mansouri, Keigo Arai
Benchmarks increasingly guide deployment, procurement and scientific screening, yet a score supports only the response it records, not necessarily the deployment action. We introdu…
The Privacy Price of Tail-Risk Learning: Effective Tail Sample Size in Differentially Private CVaR Optimization
El Mustapha Mansouri
Differential privacy changes the effective sample size governing CVaR learning. For tail mass , the privacy-relevant sample size is not , but ; equivalently, the effectiv…
