A data independent acquisition all ion fragmentation mode tool for the suspect screening of natural toxins in surface water

open access: yesMethodsX, 2021
Among natural freshwater pollutants, cyanotoxins, mycotoxins, and phytotoxins are the most important and less studied. Their identification in surface water is challenging especially cause of the lack of standards and established analytical parameters ...

Machine Learning for Absolute Quantification of Unidentified Compounds in Non-Targeted LC/HRMS

open access: yesMolecules, 2022
LC/ESI/HRMS is increasingly employed for monitoring chemical pollutants in water samples, with non-targeted analysis becoming more common. Unfortunately, due to the lack of analytical standards, non-targeted analysis is mostly qualitative. To remedy this,

Screening of Radiological Images Suspected of Containing Lung Nodules

open access: yesInternational Journal of Computer Vision and Image Processing, 2021
This paper presents a study about screening large radiological image streams produced in hospitals for earlier detection of lung nodules. Being one of the most difficult classification tasks in the literature, our objective is to measure how well state-of-the-art classifiers can screen out the images stream to keep as many positive cases as possible in

Assessment of Micro- and Nanoplastic Composition (Polymers and Additives) in the Gastrointestinal Tracts of Ebro River Fishes

open access: yesMolecules, 2022
One of the main routes of fish exposure to micro- and nanoplastics (MNPLs) is their ingestion. MNPLs can act as reservoirs of organic contaminants that are adsorbed onto their surfaces, or that can leach from their complex formulations, with potential ...
