On CR-submanifolds of the six-dimensional sphere

International Journal of Mathematics and Mathematical Sciences, 1995
We consider proper CR-submanifolds of the six-dimensional sphere S6. We prove that S6 does not admit compact proper CR-submanifolds with non-negative sectional curvature and integrable holomorphic distribution.

A transferable approach for quantifying benthic fish sizes and densities in annotated underwater images

Methods in Ecology and Evolution, Volume 16, Issue 1, Page 145-159, January 2025.
Abstract Benthic fishes are a common target of scientific monitoring but are difficult to quantify because of their close association to bottom habitats that are hard to access. Advances in image‐acquisition technologies, machine vision and deep learning have made capturing and quantifying fishes with cameras increasingly feasible.

Technical note: A biological anthropologist's guide for applying microbiome science to studies of human and non‐human primates

American Journal of Biological Anthropology, Volume 185, Issue 4, December 2024.
Abstract A central goal of biological anthropology is connecting environmental variation to differences in host physiology, biology, health, and evolution. The microbiome represents a valuable pathway for studying how variation in host environments impacts health outcomes.

CR-hypersurfaces of complex projective space

International Journal of Mathematics and Mathematical Sciences, 1994
We consider compact n-dimensional minimal foliate CR-real submanifolds of a complex projective space. We show that these submanifolds are great circles on a 2-dimensional sphere provided that the square of the length of the second fundamental form is ...

Transformer‐based framework for accurate segmentation of high‐resolution images in structural health monitoring

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 24, Page 3670-3684, 15 December 2024.
Abstract High‐resolution image segmentation is essential in structural health monitoring (SHM), enabling accurate detection and quantification of structural components and damages. However, conventional convolutional neural network‐based segmentation methods face limitations in real‐world deployment, particularly when handling high‐resolution images ...

Optimal inequalities involving Casorati curvatures for Riemannian maps to nearly Kaehler manifolds

Journal of Inequalities and Applications
We establish a general inequality and optimal inequalities involving the normalized Casorati curvatures and the generalized normalized Casorati curvatures within the horizontal space of a Riemannian map from a Riemannian manifold to a nearly Kaehler ...

Biharmonic curves along Riemannian submersions

Miskolc Mathematical Notes
The purpose of this paper is to study biharmonic curves along Riemannian submersions. We first consider a Riemannian submersion from a Riemannian manifold onto Riemannian manifold and investigate under what conditions a biharmonic curve on the total ...

CR-hypersurfaces of the six-dimensional sphere

International Journal of Mathematics and Mathematical Sciences, 1994
We proved that there does not exist a proper CR-hypersurface of S6 with parallel second fundamental form. As a result of this we showed that S6 does not admit a proper CR-totally umbilical hypersurface.

Effects of pre‐treatment, historical age, and sample characteristics on the stable isotope analyses of killer whale (Orcinus orca) bone

Rapid Communications in Mass Spectrometry, Volume 38, Issue 19, 15 October 2024.
Rationale Stable isotope analysis of bone provides insight into animal foraging and allows for ecological reconstructions over time, however pre‐treatment is required to isolate collagen. Pre‐treatments typically consist of demineralization to remove inorganic components and/or lipid extraction to remove fats, but these protocols can differentially ...

What Is the Ideal Dimension of Law?

Ratio Juris, Volume 37, Issue 3, Page 210-229, September 2024.
Abstract Various authors have claimed that law has an ideal dimension owed to a claim to correctness. Against this thesis, this article argues that there are several ideal dimensions of law, namely, a moral, a legal, and an ontological one. All of them are independent of a claim to correctness.
