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 ...

Review and Analysis of Digital Signal Processing Algorithms for Coherent Optical Satellite Links

open access: yesInternational Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 229-250, May/June 2025.
ABSTRACT Coherent optical satellite links enable high‐throughput communication and high accuracy ranging to and between satellites. Due to the ever‐increasing demand for throughput, wavelength division multiplexing of polarization multiplexed optical signals is being considered as a solution to provide high‐speed optical satellite links.

Male reproductive tactics in house mice: Consistent individual differences, intrinsic factors and density effects

open access: yesJournal of Animal Ecology, Volume 94, Issue 6, Page 1244-1258, June 2025.
This study investigates alternative reproductive tactics (ARTs) in male house mice and establishes a comprehensive framework for their maintenance. It provides new insights into the expression of ARTs and the factors influencing male reproductive success and survival, with implications for adaptation in changing environments.
