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.

The Lost Large Mammals of Arabia

open access: yesJournal of Biogeography, Volume 52, Issue 6, June 2025.
ABSTRACT Aim If successful, plans to restore the vegetation of the Arabian Peninsula (AP) as announced by the Middle East and Saudi Green Initiatives will see the greatest increase in vegetation cover since the beginning of the Holocene Humid Phase (HHP), roughly 9–10,000 years ago.

Feasibility of a Finger Food Menu for Older Adults Post Stroke in Hospital

open access: yesJournal of Human Nutrition and Dietetics, Volume 38, Issue 3, June 2025.
ABSTRACT Background Many people in hospital after a stroke are at risk of reduced food intake, leading to less effective post‐stroke recovery. Finger foods (foods that can be easily transferred from the plate to the mouth without cutlery) have the potential to increase food intake and enable mealtime independence.
