Metamorphic or Igneous Zircon? Classification Through Rare Earth Elements, Machine Learning and Logistic Regression

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Zircon is a common, highly refractory accessory mineral found in sedimentary, igneous and metamorphic rocks that forms through various processes (e.g., magmatic, hydrothermal, metamorphic growth and recrystallization). Trace element compositions of detrital zircon have been widely applied to understanding tectonic processes and continental ...

Erythrocyte ‘Feierzeit’ reaction: Novel filamentous and vesicular response to n‐butyl acetate

open access: yesJournal of Microscopy, EarlyView.
Abstract Human erythrocytes (red blood cells; RBCs) undergo spontaneous disassembly after several hours of exposure to n‐butyl acetate (nBA). Images of the morphological changes were captured in time‐lapse sequences using differential interference contrast (DIC) light microscopy.

Data Sharing in Hybrid Marketplaces With Endogenous Fee Setting

open access: yesThe Journal of Industrial Economics, EarlyView.
ABSTRACT We study a hybrid marketplace where a vertically integrated platform competes with a seller, who pays the platform a transaction fee, in a horizontally differentiated downstream market. The platform has a data advantage that allows it to price discriminate against consumers and can choose to share such data with the seller. First, in a setting

Topological, Functional, and Phylogenetic Analysis of the Cell Division Site Selection Protein MinJ of Bacillus subtilis

open access: yesMolecular Microbiology, EarlyView.
MinJ is a nine‐pass transmembrane protein with a cytoplasmic PDZ domain. The PDZ domain, while required for division, is dispensable for localization, and deletion of the transmembrane segments 6 and 7 results in a hyper‐minicell phenotype. ABSTRACT The Min system disassembles FtsZ‐rings after septation in Bacillus subtilis and is localized to the ...

Plant NAOGAT (ArgJ) Structure Reveals Mechanism of Ornithine Biosynthesis, Preference for Acetylornithine and Susceptibility to Mangotoxin

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Arginine metabolism in plants is targeted by phytopathogens such as Pseudomonas syringae strains, which produce toxins that affect enzymes of plant arginine metabolism, causing devastating infections in crops. In this work, the structural and functional properties of plant N‐acetylornithine glutamate acetyltransferase (NAOGAT), the key ...

Response of Melissa officinalis subsp. officinalis seedlings to Fe3O4‐NPs under in vitro conditions: physiological, biochemical and molecular analyses

open access: yesPlant Biology, EarlyView.
Iron oxide nanoparticles influence the growth, antioxidant capacity, and gene activity of Melissa officinalis subsp. officinalis plants in vitro, revealing their potential as modulators of secondary metabolism. Abstract Application of iron oxide nanoparticles (NP) (Fe3O4‐NPs) in plant biotechnology presents new opportunities for enhancing metabolic ...
