Improved Artificial Bee Colony Algorithm and Its Application to Fundus Retinal Blood Vessel Image Binarization

The content of this work is based on the characteristics of standard artificial bee colony(ABC) algorithm with weak local search ability and slow convergence speed.Then, an improved algorithm named KD-ABC is proposed.For improving the diversity and quality of the solution, it changes the generation method of honey source.In the initialization phase

Ontogenetic changes in the craniomandibular skeleton of the abelisaurid dinosaur Majungasaurus crenatissimus from the Late Cretaceous of Madagascar

Abelisaurid theropods were one of the most diverse groups of predatory dinosaurs in Gondwana during the Cretaceous.The group is characterized by a tall, wide skull and robust cervical region.This morphology is thought to have facilitated specialized feeding behaviors such as prolonged contact with prey.The Late Cretaceous abelisaurid Majungasaurus
