Exploiting Multitask Deep Learning to Identify Multiple Heavy Metal Contamination at Large Scales

open access: yesAdvanced Intelligent Systems, EarlyView.
A multitask deep learning framework evaluates manganese, chromium, and cobalt concentrations in European soils, achieving an average R2 of 0.75. From 2009 to 2015, soil concentrations increase significantly. Source analysis identifies anthropogenic manganese and geological chromium and cobalt origins.

Vertical movements along the northwestern side of Messina straits, in the 1967-1970 period

open access: yesAnnals of Geophysics, 1982
The results of a comparison of the spirit levelling data made by I.G.M. in 1967<br />and in 1970, are presented. An analysis of these data shows that the altitude<br />variations of bench marks in the considered triennial period seem to ...

Harnessing halophyte‐derived allelochemicals and signaling molecules to enhance salinity tolerance in crops

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Soil salinization is a growing global challenge that significantly reduces agricultural productivity by impairing seed germination, growth, and yield. While conventional crops have limited tolerance to high salinity, halophytes are promising biological models for developing strategies to sustain agriculture in saline environments and ...

Effects of Fire and Explosion Event in a Rural Area Fuel Depot Tank Farm: A Case Study From Istanbul, Türkiye

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Chemical facilities storing large volumes of flammable liquids close to residential areas pose severe fire‐and‐explosion hazards that can escalate into disasters. In this study, a tank farm located within Istanbul's city limits is examined to evaluate possible catastrophic scenarios using consequence analysis methods. For this purpose, several

Predicted Potential for Aquatic Exposure Effects of Per- and Polyfluorinated Alkyl Substances (PFAS) in Pennsylvania’s Statewide Network of Streams

open access: yesToxics
Per- and polyfluoroalkyl substances (PFAS) are contaminants that can lead to adverse health effects in aquatic organisms, including reproductive toxicity and developmental abnormalities. To assess the ecological health risk of PFAS in Pennsylvania stream

Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing‐bite among saber‐toothed predators?

open access: yesThe Anatomical Record, EarlyView.
Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Morphological diversity of saber‐tooth upper canines and its functional implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Elongated upper canine teeth, commonly known as saber‐teeth, have evolved three times within the sub‐order Feliformia. The species that wielded them flourished throughout the Cenozoic and have historically been separated into two morphological groups: the dirk‐tooths with longer, flatter canines, and the scimitar‐tooths with shorter, serrated ...
