SlGRF1 mediates gibberellin signaling to control cut‐budding in tomato

open access: yesJournal of Integrative Plant Biology, EarlyView.
Upon wounding, cytokinin increases to initiate callus formation. Gibberellin enhances this, but later blocks bud formation by suppressing SlGRF1. Wounding‐induced protein SlGRF1 triggers buds via NAM1, EPF4, and ER2. Hormonal shifts control cut‐budding phases.

Process Planning for Large Container Ship Propeller Shaft Machining Based on an Improved Ant Colony Algorithm

open access: yesJournal of Marine Science and Engineering
To accommodate the production and manufacture of complex and customized marine components and to avoid the empirical nature of process planning, machining operations can be automatically sequenced and optimized using ant colony algorithms.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Automatic Programming with Ant Colony Optimization [PDF]

open access: yes, 2004
Automatic programming is the use of search techniques to find programs that solve a problem. The most commonly explored automatic programming technique is genetic programming, which uses genetic algorithms to carry out the search.

Evolution of Crematogaster sordidula (Hymenoptera, Formicidae) Ants in the Mediterranean Region During Plio‐Pleistocene Climatic Changes

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Understanding insect responses to global climate change involves identifying strategies used during past climate oscillations. Phylogeography offers a powerful framework to unravel how historical climatic and geological events have shaped the spatial genetic patterns of species, providing critical insights into evolutionary processes, whereas ...

Automatic MGA trajectory planning with a modified ant colony optimization algorithm

open access: yes, 2009
This paper assesses the problem of designing multiple gravity assist (MGA) trajectories, including the sequence of planetary encounters. The problem is treated as planning and scheduling of events, such that the original mixed combinatorial-continuous ...
