Application and interpretation of functional data analysis techniques to differential scanning calorimetry data from lupus patients. [PDF]

PLoS ONE, 2017
DSC is used to determine thermally-induced conformational changes of biomolecules within a blood plasma sample. Recent research has indicated that DSC curves (or thermograms) may have different characteristics based on disease status and, thus, may be ...

Patterns of weight gain during the first half of pregnancy and risk of large newborns in women with insulin-dependent diabetes mellitus. [PDF]

Pregnancy (Hoboken)
Abstract Objective To identify patterns of gestational weight gain (pGWG) trajectories in the first 20 weeks of gestation and to determine the association of these patterns with the delivery of large‐for‐gestational‐age (LGA) infants among women with insulin‐dependent diabetes mellitus (IDDM).

A Novel Longitudinal Proteomic Aging Index Predicts Mortality, Multimorbidity, and Frailty in Older Adults. [PDF]

Aging Cell
We used proteomic data from three longitudinal visits in the ARIC study to construct a single longitudinal proteomic aging index (LPAI) that captures both cumulative aging burden and dynamic aging trajectories. Higher LPAI was associated with increased risks of mortality, frailty, and multimorbidity.

Unvealing the Principal Modes of Human Upper Limb Movements through Functional Analysis

Frontiers in Robotics and AI, 2017
The rich variety of human upper limb movements requires an extraordinary coordination of different joints according to specific spatio-temporal patterns. However, unvealing these motor schemes is a challenging task.

Phenological Variation and Evolution Across Space and Time in the Scarlet Monkeyflower (<i>Erythranthe cardinalis</i>). [PDF]

Ecol Evol
Climate change is altering ecological dynamics, particularly in species with latitudinal range variation. This study investigates how the scarlet monkeyflower's flowering phenology has evolved in response to recent droughts in California. We find that southern populations are flowering later and larger, while northern populations flower earlier and ...

Recognition and Characterization of Forest Plant Communities through Remote-Sensing NDVI Time Series

Diversity, 2020
Phytosociology is a reference method to classify vegetation that relies on field data. Its classification in hierarchical vegetation units, from plant associations to class level, hierarchically reflects the floristic similarity between different sites ...
