Maximizing NMR Sensitivity: A Guide to Receiver Gain Adjustment

open access: yesNMR in Biomedicine, Volume 38, Issue 6, June 2025.
NMR applications expand with technological advances, but sensitivity remains a key challenge addressed by methods like hyperpolarization. Optimizing signal‐to‐noise (SNR) is complex, especially in hyperpolarization where automatic receiver gain (RG) adjustment is difficult.

Safety Filters Against Actuator Attacks

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 35, Issue 9, Page 3640-3657, June 2025.
ABSTRACT This manuscript focuses on mitigating the effect of deception attacks on control signals, that is, in the presence of an adversary that tampers with data coming from the controller to the system actuators in order to degrade the plant performance.

Assessment of Practical Satellite Quantum Key Distribution Architectures for Current and Near‐Future Missions

open access: yesInternational Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.
ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...
