Acoustic animal identification using unsupervised learning

open access: yesMethods in Ecology and Evolution, 2023
Passive acoustic monitoring is usually presented as a complementary approach to monitoring wildlife communities and assessing ecosystem conditions. Automatic species detection methods support biodiversity monitoring and analysis by providing information ...

Cluster-cluster clustering

open access: yesThe Astrophysical Journal, 1985
The cluster correlation function xi sub c(r) is compared with the particle correlation function, xi(r) in cosmological N-body simulations with a wide range of initial conditions. The experiments include scale-free initial conditions, pancake models with a coherence length in the initial density field, and hybrid models.

Measuring connectedness among herds in mixed linear models: From theory to practice in large-sized genetic evaluations

open access: yesGenetics Selection Evolution, 2008
A procedure to measure connectedness among groups in large-sized genetic evaluations is presented. It consists of two steps: (a) computing coefficients of determination (CD) of comparisons among groups of animals; and (b) building sets of connected ...

Machine Learning in Amyotrophic Lateral Sclerosis: Achievements, Pitfalls, and Future Directions

open access: yesFrontiers in Neuroscience, 2019
Background: Amyotrophic Lateral Sclerosis (ALS) is a relentlessly progressive neurodegenerative condition with limited therapeutic options at present. Survival from symptom onset ranges from 3 to 5 years depending on genetic, demographic, and phenotypic ...

Inherent atomic mobility changes in carbocation intermediates during the sesterterpene cyclization cascade

open access: yesBeilstein Journal of Organic Chemistry, 2019
We previously showed that the regio- and stereoselectivity in terpene-forming reactions are determined by the conformations of the carbocation intermediates, which reflect the initial conformation of the substrate, geranylfarnesyl diphosphate (GFPP ...

Seismic Signal Compression Using Nonparametric Bayesian Dictionary Learning via Clustering

open access: yesAlgorithms, 2017
We introduce a seismic signal compression method based on nonparametric Bayesian dictionary learning method via clustering. The seismic data is compressed patch by patch, and the dictionary is learned online.

Histology-informed automatic parcellation of white matter tracts in the rat spinal cord

open access: yesFrontiers in Neuroanatomy, 2022
The white matter is organized into “tracts” or “bundles,” which connect different parts of the central nervous system. Knowing where these tracts are located in each individual is important for understanding the cause of potential sensorial, motor or ...
