The 2‐divisibility of divisors on K3 surfaces in characteristic 2
Mathematische Nachrichten, Volume 298, Issue 6, Page 1964-1988, June 2025.Abstract We show that K3 surfaces in characteristic 2 can admit sets of n$n$ disjoint smooth rational curves whose sum is divisible by 2 in the Picard group, for each n=8,12,16,20$n=8,12,16,20$. More precisely, all values occur on supersingular K3 surfaces, with exceptions only at Artin invariants 1 and 10, while on K3 surfaces of finite height, only n=

International 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 ...

Benefit‐sharing with human participants in health research in South Africa: A call for clarity
Developing World Bioethics, Volume 25, Issue 2, Page 144-153, June 2025.Abstract This study critically examines the concept of benefit‐sharing in the context of health research involving human participants in South Africa, identifying a significant gap in the precision and application of terminology. It introduces a new terminological framework designed to provide clarity and facilitate standardisation in both national and
