Post-Quantum Cryptography: S381 Cyclic Subgroup of High Order

open access: yes, 2017
Currently there is an active Post-Quantum Cryptography (PQC) solutions search, which attempts to find cryptographic protocols resistant to attacks by means of for instance Shor polynomial time algorithm for numerical field problems like integer ...

Trait‐mediated effects driven by an invasive herbivore alter functionally diverse plant–frugivore interactions

open access: yesFunctional Ecology, Volume 40, Issue 1, Page 216-228, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits play a fundamental role in mediating plant‐frugivore interactions, shaping seed dispersal dynamics. Given the complexity of multi‐species interactions, these traits and, consequently, plant‐frugivore interactions can be indirectly influenced by third‐party ...

Patrones formales e interpretación: el funcionamiento de más en español

open access: yesEstudios de Lingüística, 2009
Se estudia el funcionamiento sintáctico del operador aditivo más en español, tanto en su variante simétrica (dos más dos) como en la asimétrica (dos días más; más de dos días) y se propone un análisis unitario que derive este último valor de ...

Climate and hybridization shape stomatal trait evolution in Populus

open access: yesNew Phytologist, Volume 249, Issue 2, Page 792-809, January 2026.
Summary Stomata play a critical role in regulating plant responses to climate. Where sister species differ in stomatal traits, interspecific gene flow can influence the evolutionary trajectory of trait variation, with consequences for adaptation. Leveraging six latitudinally distributed contact zones spanning the natural hybrid zone between Populus ...

The voyage of the Serliana motif, a journey to understand the transmission of architectural values through space and time [PDF]

open access: yes, 2019
Following the idea of a drastic reduction of linguistic tools in the early Renaissance we have to assume a recovery of the Serliana motif only in the 16th century, after its practical disappearance for several centuries.

Reduced Offspring Viability Is Associated With Long‐Term Stability of a Narrow Avian Hybrid Zone

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
We investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...
