Sistema de inferencia difusa basado en relaciones Booleanas

open access: yesIngeniería, 2010
Este documento describe la estructura de un sistema de inferencia difusa basado en relaciones booleanas. La teoría relacionada con lógica y conjuntos booleanos es una buena herramienta para el diseño de automatismos y sistemas digitales.

Observing the invisible: X‐ray CT for plant–microbe interactions

open access: yesNew Phytologist, Volume 251, Issue 3, Page 959-966, August 2026.
Utility of X‐ray computed tomography (X‐ray CT) for visualising belowground plant interactions between multiple spatial scales and focal planes. Summary Plant–microbe interactions are inherently spatial, yet the physical structure of the soil and rhizosphere is rarely treated as a mechanistic variable in experimental design.

Temperate tree species show cross‐tolerance to heat, drought, and late spring‐frost stress

open access: yesNew Phytologist, Volume 251, Issue 4, Page 1625-1630, August 2026.
Significant cross‐tolerance of leaf traits to heat, drought and late spring‐frost were found. (a) Turgor loss point vs lethal spring‐frost temperature. (b) Heat thermal threshold temperature vs lethal spring‐frost temperature. (c) Heat thermal threshold temperature vs turgor loss point.

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

open access: yesNew Phytologist, Volume 251, Issue 4, Page 2237-2247, August 2026.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Arabidopsis DNA repair mutants can integrate Agrobacterium T‐DNA into the plant genome

open access: yesNew Phytologist, Volume 251, Issue 4, Page 1811-1822, August 2026.
Transient (a) and stable (b) transformation of Arabidopsis thaliana DNA repair/recombination mutants grown under normal light conditions. Summary Agrobacterium transfer DNA (T‐DNA) integration is mediated by plant DNA repair proteins of various nonhomologous end‐joining (NHEJ) pathways.

Trimerous magnoliid flowers with a unique set of floral and pollen traits from the Late Cretaceous of Southern Bohemia (Czech Republic)

open access: yesNew Phytologist, Volume 251, Issue 4, Page 2266-2283, August 2026.
Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...
