Aggregated functional data model for Near-Infrared Spectroscopy calibration and prediction [PDF]
Calibration and prediction for NIR spectroscopy data are performed based on a functional interpretation of the Beer-Lambert formula. Considering that, for each chemical sample, the resulting spectrum is a continuous curve obtained as the summation of ...

ABSTRACT The multi‐elemental profile has repeatedly been proposed as a reliable indicator of the geographical origin of plant‐derived foods, as mineral composition accurately reflects the local soil geochemistry and environmental factors. However, this approach may fail in distinguishing specimens from nearby locations, which are expected to be exposed

Abstract Water scarcity is a major threat to crop production and quality. Improving drought tolerance through variety selection requires a deeper understanding of plant ecophysiological responses, but large‐scale phenotyping remains a bottleneck. This study assessed the potential of high‐throughput tools (spectroscopy and poro‐fluorometry) to predict ...

ABSTRACT Various factors can trigger water stress in plants, particularly in those growing in dry tropical regions. To survive under such conditions, plants produce metabolites with adaptive functions. However, metabolomic data on the leaves of Malpighiaceae species cultivated in both dry and humid tropical areas of Brazil remain scarce.

ABSTRACT The properties and aggregations of anionic surfactants change strongly in the presence of multivalent cations. Therefore, the knowledge of the binding of multivalent metal ions to the headgroups of anionic surfactants can be helpful for the applications of surfactants in various fields. This paper presents an analysis of the interactions of 14

Fingerprint analysis of biological samples using ICP-MS and IR-MS [PDF]
Atomic spectroscopy based analytical techniques can generate fingerprints encompassing the vast majority of elements found in the periodic table as well as ratios of their stable isotopes. These highly multivariate fingerprints have laid the foundation
