A machine learning assisted method for rapidly annotating benthic megafauna in large volumes of marine imagery

Limnology and Oceanography: Methods, EarlyView.
Abstract Recent technological advancements have rapidly expanded our capacity for collecting image data in the marine environment, but processing images into meaningful ecological metrics remains a manual, time‐consuming, and biased process. This is particularly challenging with electro‐optical cabled imaging systems which generate images at a rate ...

Discrete element analysis of macro- and micro-mechanical properties of methane hydrate-bearing clay under different salinities

Yantu gongcheng xuebao
The mechanical behavior of methane hydrate bearing soil is closely related to the characteristics of hydrate phase equilibrium. Compared with sand, clay has smaller pore size and the pore size has a great influence on the characteristics of hydrate phase

Microphysical chemistry of fog–aerosol interactions over the northwest Atlantic Ocean during Fatima 2022

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Fifteen size‐resolved aerosol samples collected during marine fog, with adjacent ambient observations, show that coarse sea salt aerosol is rapidly grown and lost in the northwest North Atlantic Ocean except when subject to extreme winds. The persistence of fog in the absence of sea salt is determined by available fine‐mode aerosol, where greater ...

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

steel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

Reactivity of the Iron Complexes with the Macrocyclic Ligand 5,5,7,12,12,14‐Hexamethyl‐1,4,8,11‐Tetraazacyclotetradecane (tet) Toward Dioxygen

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The complex [(tet a)FeII(OTf)2] reacts with dioxygen first to a superoxido intermediate and in a consecutive reaction to the corresponding iron–oxido complex. The reactions of the iron complexes [(tet a)FeII(OTf)2] and [(tet b)FeII](OTf)2 (tet = 5,5,7,12,12,14‐hexamethyl‐1,4,8,11‐tetraazacyclotetradecane) with dioxygen were investigated.
