Novelty Detection Under Multi-Instance Multi-Label Framework
, 2013 Novelty detection plays an important role in machine learning and signal processing. This paper studies novelty detection in a new setting where the data object is represented as a bag of instances and associated with multiple class labels, referred to ...

A computational framework to characterize and compare the tonal repertoires of toothed whales
Methods in Ecology and Evolution, EarlyView.Abstract Toothed whales, despite being one of the most acoustically specialized lineages of vertebrates, lack detailed vocal repertoire characterizations comparable to those of songbirds and primates. Current descriptions often lack standardization, limiting interspecies and intraspecies comparisons critical for understanding the contribution of ...

Challenges and opportunities for bioacoustics in the study of rare species in remote environments
Conservation Science and Practice, 2023 For many habitat specialists, data deficiencies are directly attributable to the rugged terrain they inhabit. Based on a recent survey effort for one such species, the threatened Yosemite toad (Anaxyrus canorus), we describe the prospects for acoustic ...

Re‐make, re‐model: evolution and development of vertebrate cranial lateral lines
Biological Reviews, EarlyView.ABSTRACT Lateral lines are placodally derived mechanosensory systems on the heads and trunks of many aquatic vertebrates. There is evidence of lateral lines in the earliest known vertebrate fossils, and they exist in organisms with widely different craniofacial morphologies – including the presence or absence of jaws, external or internal nostrils, and

Assessing spatial variability and efficacy of surrogate species at an ecosystem scale
Conservation Biology, EarlyView.Abstract Preserving biodiversity is a central goal of conservation, but, in practice, monitoring biodiversity often involves assessing population trends for one or a handful of species that are presumed proxies for biodiversity. Despite the popularity of surrogate species strategies, the links between biodiversity and surrogate species are rarely ...

Cell Proliferation, EarlyView.Ezh2‐deficient astrocytes showed morphologically more slender but sparse dendrites, resulting in reduced endfoot coverage and also causing disruption of the blood–brain barrier. ABSTRACT Astrocytes are crucial for central nervous system (CNS) development and function, with their differentiation being stringently controlled by epigenetic mechanisms ...
