Chemical Recruitment for Foraging in Ants (Formicidae) and Termites (Isoptera): A Revealing Comparison by Klaus Jaffe, Solange Issa, Cristina Sainz-Borgo

“…All termites secrete trail pheromones from their sternal gland, whereas ants use a variety of glands for this purpose. This and the diversity of chemical compounds that serve as trail pheromones among ants, and the uniformity of chemicals among termite trails, suggest a different evolutionary historical dynamics for the development of chemical mass recruitment in both taxa. …”

Multi-AGV multitask collaborative scheduling based on an improved ant colony algorithm by Yazhen Zhu, Qing Song, Meng Li

“…This paper establishes a mathematical model with the optimization objective of minimizing the overall running time of material distribution tasks and proposes an improved ant colony algorithm to optimize the model. First, the concept of prior time is introduced to improve the traditional ant colony algorithm. …”

Clustering Ant Colony-Based Edge-Server Location Strategy in Mobile Crowdsensing by Ahmed. A. A. Gad-Elrab, Amin Y. Noaman

“…To solve this problem, two edge-server location strategies are proposed, which use a clustering method for dividing the set of mobile users with data items into clusters and use the ant colony approach to select a mobile edge server for each data type in each cluster. …”

Europa y Estados Unidos ante los Derechos Humanos en Cuba by Susanne Gratius

“…Al ser diferentes, las políticas de la UE y EEUU incluso han contribuido a mantener el régimen castrista en el poder: la UE por su reconocimiento diplomático y la cooperación económica; EEUU, al proporcionar una imagen de enemigo externo. Por ello, y ante el nuevo panorama que ofrece el cambio de gobierno en Cuba, la próxima revisión de la Posición Común de la UE y las elecciones presidenciales en EEUU, es necesario replantearse los objetivos y estrategias políticas para incentivar los derechos humanos en Cuba.…”
