Compositional and Bioactive Differentiation of Opuntia spp. Fruit Varieties by PCA and LDA [PDF]

Foods
The nutritional, mineral, and bioactive profiles of four Opuntia fruit varieties—Opuntia robusta red variety (OR-RV) and three Opuntia ficus-indica varieties (red, yellow, and green: OFI-RV, OFI-YV, and OFI-GV, respectively)—were characterized to assess ...

Automated Mango Variety Classification Using Deep Feature Extraction and Machine Learning Classifier Integration [PDF]

Foods
Manual mango variety classification is time-consuming, error-prone, and contributes significantly to post-harvest losses in developing economies. This study aims to develop a computationally efficient and highly accurate artificial intelligence framework

Discriminants of toric varieties [PDF]

Communications in Algebra, 2021
We study the subvariety of singular sections, the discriminant, of a base point free linear system $|L|$ on a smooth toric variety $X$. On one hand we describe pairs $(X,L)$ for which the discriminant is of low dimension. Precisely, we collect some bounds on this dimension and classify those pairs whose dimension differs the bound less than or equal to

Highly dispersive optical soliton perturbation with Kerr law for complex Ginzburg–Landau equation [PDF]

Proceedings of the Estonian Academy of Sciences, 2023
In this paper, highly dispersive optical solitons are obtained with the perturbed complex Ginzburg–Landau equation, incorporating the Kerr law of nonlinearity, by the complete discriminant classification approach.

Variety Discrimination Power: An Appraisal Index for Loci Combination Screening Applied to Plant Variety Discrimination [PDF]

Frontiers in Plant Science, 2021
Molecular marker technology is used widely in plant variety discrimination, molecular breeding, and other fields. To lower the cost of testing and improve the efficiency of data analysis, molecular marker screening is very important. Screening usually involves two phases: the first to control loci quality and the second to reduce loci quantity.

Classification of Coffea canephora clones in botanical varieties by discriminant analysis of the k-nearest neighbors

Revista Ceres, 2021
A strategy for genetic improvement of coffee Coffea canephora plants is to aggregate through artificial crossings the characteristics of the Conilon botanical variety, such as shorter height and drought resistance, with the higher average grain size and ...
