Evaluating multiannual sedimentary nutrient retention in agricultural two-stage channels.

Sci Rep

January 2025

Environmental Geochemistry group, Department of Geosciences and Geography, University of Helsinki, Helsinki, Finland.

The two-stage channel (TSC) design with a vegetated man-made floodplain has been recommended as an alternative to conventional re-dredging for managing suspended sediment (SS) and nutrient loads in agricultural streams. However, there are currently uncertainties surrounding the efficiency of TSCs, since mass balances covering the whole annual hydrograph and including different periods of the channel life cycle are lacking. This paper aims to improve understanding of the medium-term morphological development and sedimentary nutrient retention when a dredged, trapezoidal-shaped channel is converted into a TSC, using a mass balance estimate of nutrient and carbon retention from immediately after excavation until the establishment of approximate biogeochemical equilibrium retention.

Objectives: The purpose of this study was to investigate the fundamental properties of spot-scanning proton beams and compare them to Monte Carlo (MC) simulations, both with and without CT calibration, using spatially diverse combinations of materials.

Methods: A heterogeneous phantom was created by spatially distributing titanium, wax, and thermocol to generate six scenarios of heterogeneous combinations. Proton pencil beams ranging in energy from 100 to 226.

This study explores FD/MAS patient's perceptions about their disease and its impact on their quality of life. We have evaluated quality of life (QoL) in French Fibrous Dysplasia/MacCune-Albright Syndrome (FD/MAS) patients using a qualitative approach with focus groups to explore perceptions, symptoms and limitations associated with FD/MAS and a quantitative method with the Short Form-36 (SF36) to quantify QoL. Focus groups revealed the heterogeneity of FD forms and allowed for understanding the reasons of reduced QoL.

Objective: Recognizing glomerular lesions is essential in diagnosing chronic kidney disease. However, deep learning faces challenges due to the lesion heterogeneity, superposition, progression, and tissue incompleteness, leading to uncertainty in model predictions. Therefore, it is crucial to analyze pathology-related predictive uncertainty in glomerular lesion recognition and unveil its relationship with pathological properties and its impact on model performance.

Thyroid cytopathology, particularly in cases of atypia of undetermined significance/follicular lesions of undetermined significance (AUS/FLUS), suffers from suboptimal sensitivity and specificity challenges. Recent advancements in digital pathology and artificial intelligence (AI) hold promise for enhancing diagnostic accuracy. This systematic review included studies from 2000 to 2023, focusing on diagnostic accuracy in AUS/FLUS cases using AI, whole slide imaging (WSI), or both.
