AVES: Animal Vocalization Encoder Based on Self-Supervision [PDF]

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2022
The lack of annotated training data in bioacoustics hinders the use of large-scale neural network models trained in a supervised way. In order to leverage a large amount of unannotated audio data, we propose AVES (Animal Vocalization Encoder based on ...

High rates of evolution preceded the origin of birds [PDF]

, 2014
The origin of birds (Aves) is one of the great evolutionary transitions. Fossils show that many unique morphological features of modern birds, such as feathers, reduction in body size, and the semilunate carpal, long preceded the origin of clade Aves ...

Pathogenic variability among Pasteurella multocida type A isolates from Brazilian pig farms

BMC Veterinary Research, 2018
Background Pasteurella multocida type A (PmA) is considered a secondary agent of pneumonia in pigs. The role of PmA as a primary pathogen was investigated by challenging pigs with eight field strains isolated from pneumonia and serositis in six Brazilian
