An Example of Parallel Merkle Tree Traversal: Post-Quantum Leighton-Micali Signature on the GPU
ACM Transactions on Architecture and Code Optimization (TACO)The hash-based signature (HBS) is the most conservative and time-consuming among many post-quantum cryptography (PQC) algorithms. Two HBSs, LMS and XMSS, are the only PQC algorithms standardised by the National Institute of Standards and Technology (NIST)

Mammal Review, Volume 56, Issue 1, March 2026.Black bears as apex predators. American black bears can (1) produce top‐down effects on ungulates equal to or exceeding those of typical apex predators and (2) modify the spatiotemporal behaviour of other carnivores, including pumas and coyotes. We argue that the term ‘apex predator’ is highly context dependent and not a species‐wide status.
