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

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
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 ...

Characterization and differentiation of myocardial remodeling using artificial intelligence‐assisted confocal Raman spectroscopy imaging

open access: yesVIEW, EarlyView.
Myocardial remodeling is a key factor in heart failure. Rats were treated with ISO to induce remodeling, confirmed by echocardiography and staining. Confocal Raman spectroscopy imaging provided detailed insights into tissue architecture and the differentiation of regions.
