Allometric Models to Estimate Leaf Area for Tropical African Broadleaved Forests

Geophysical Research Letters, 2019
Direct and semidirect estimations of leaf area (LA) and leaf area index (LAI) are scarce in dense tropical forests despite their importance in calibrating remote sensing products, forest dynamics, and biogeochemical models.

Probability of ventricular fibrillation: allometric model based on the ST deviation [PDF]

BioMedical Engineering OnLine, 2011
Abstract Background Allometry, in general biology, measures the relative growth of a part in relation to the whole living organism. Using reported clinical data, we apply this concept for evaluating the probability of ventricular fibrillation based on the electrocardiographic ST-segment deviation values.

Longitudinal Echocardiographic Surveillance of Aortic Dilation in a Phenotype‐Enriched Turner Syndrome Cohort

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Turner syndrome (TS) is associated with thoracic aortopathy and increased risk for aortic dissection, yet the natural history of aortic dilation is not well understood. We performed a retrospective longitudinal study of individuals with TS who participated in the TS Society of the United States Healthy Heart Project between 2003 and 2023 ...

Terrestrial laser scanning-based allometric models for East-African tropical rainforest trees

Trees, Forests and People
An in-depth understanding of tree allometry is a crucial prerequisite to quantify the role of tropical forests in global carbon cycling. Here, we present site-specific, multi-species allometric models to quantify height, crown length, crown projection ...

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

The Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Estimating aboveground live understory vegetation carbon in the United States

Environmental Research Letters, 2017
Despite the key role that understory vegetation plays in ecosystems and the terrestrial carbon cycle, it is often overlooked and has few quantitative measurements, especially at national scales.

Joint multiple quantitative trait loci mapping for allometries of body compositions and metabolic traits to body weights in broiler

Animal, 2020
In order to map quantitative trait loci (QTLs) for allometries of body compositions and metabolic traits in chicken, we phenotypically characterize the allometric growths of multiple body components and metabolic traits relative to BWs using joint ...

Predicting aboveground biomass carbon sequestration potential in hybrid poplar clones under afforestation plantation management in southern Ontario, Canada

The Forestry Chronicle, 2022
Afforestation systems as a pathway for natural climate solutions contributing to terrestrial C sequestration are influenced by agroclimatic conditions, tree species and clones.

Spectral Clustering Algorithm for the Allometric Extension Model

Statistical Papers
The spectral clustering algorithm is often used as a binary clustering method for unclassified data by applying the principal component analysis. To study theoretical properties of the algorithm, the assumption of conditional homoscedasticity is often supposed in existing studies.
