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 ...

When Structure and Content of Socioscientific Argumentation Develop in an Unbalanced Way: A Case Study

open access: yesScience Education, EarlyView.
ABSTRACT To cultivate the capability of making informed decisions on socioscientific issues, ideally, we hope students would engage in discerning and evaluating justifications for and against different positions while constructing well‐structured, persuasive arguments.

The Role of Free Radicals and Antioxidant in Abortion [PDF]

open access: yes, 2013
BACKGROUND: Free radicals and antioxidant exist in balance under normal condition. In prooxidant condition, excessive free radicals can initiate a state of oxidative stress (OS) followed by capillary endothelial cell damage, a process involved in the ...

Recurrence on the average on trees [PDF]

open access: yesarXiv, 2002
In this paper we show that all infinite trees which have bounded coordination and whose surface is negligible with respect to the volume in the limit of large distances (so that they can be embedded in a finite-dimensional euclidean space) are recurrent on the average; this has important consequences about the spontaneous symmetry breaking of ...

Recoverable, Abortable, and Adaptive Mutual Exclusion with Sublogarithmic RMR Complexity [PDF]

open access: yesarXiv, 2020
We present the first recoverable mutual exclusion (RME) algorithm that is simultaneously abortable, adaptive to point contention, and with sublogarithmic RMR complexity. Our algorithm has $O(\min(K,\log_W N))$ RMR passage complexity and $O(F + \min(K,\log_W N))$ RMR super-passage complexity, where $K$ is the number of concurrent processes (point ...
