Investigating Shape Variation Using Generalized Procrustes Analysis and Machine Learning

Applied Sciences, 2022
The biological investigation of a population’s shape diversity using digital images is typically reliant on geometrical morphometrics, which is an approach based on user-defined landmarks.

Changes in the Sensory Odor Profile during Chorizo Maturation and Their Relationship with Volatile Compound Patterns by Partial Least Square Regression (PLS)

Foods, 2023
Odor is one of the most important attributes to determine the overall acceptance of a product. The aim of this investigation is to evaluate the changes in the odor profile and the volatile compounds during thirty-three days of ripening to obtain the ...

Profound effect of profiling platform and normalization strategy on detection of differentially expressed microRNAs--a comparative study. [PDF]

PLoS ONE, 2012
BACKGROUND: Adequate normalization minimizes the effects of systematic technical variations and is a prerequisite for getting meaningful biological changes. However, there is inconsistency about miRNA normalization performances and recommendations. Thus,

Human calcaneal variation relative to subsistence strategy, activity level, and footwear

Frontiers in Earth Science, 2023
Lower limb cortical and trabecular bone varies with human behavior, leading to suggestions that activity level decreases have contributed to a more gracile skeleton.

Methodological proposal for the characterization of accessions in Germplasm Banks using Generalized Procrustes Analysis applied to incomplete but connected trials

Revista de la Facultad de Ciencias Agrarias, 2021
Characterization of plant material conserved in germplasm banks allows the study and analysis of the genetic variability within a collection. When germplasm banks have a large number of accessions, field evaluation should be performed using assays ...

Developing a Descriptive Sensory Characterization of Flour Tortilla Applying Flash Profile

Foods, 2021
For any food, it is important to know consumption, preference, and the characteristics as quality parameters that are important to consumers of a product. The descriptive methodologies are an important tool to know the quality attributes of the products.

A contribution to the knowledge of Scots pine (Pinus sylvestris L.) stem shape

Journal of Forest Science, 2004
This is a study on the evaluation of stem shape in Scots pine. The experiments were carried out on 430 stems without bark, taken from 30 fully analysed sample trees that grew in 5 different locations in the Czech Republic. Generalized Procrustes analysis
