Machine Learning Reveals Magmatic Fertility of Skarn-Type Tungsten Deposits
Applied SciencesThe chemical composition of apatite has been utilized as an indicator of magmatic fertility related to tungsten mineralization in skarn systems. In this study, we compiled 5776 apatite trace element data from 374 intrusions, along with records indicating

, 2022 After comparing four commonly employed machine learning algorithms, we chose a scalable end-to-end tree boosting system called XGBoost as the optimal algorithm to tune and yield the final classifiers. It provides a rapid and highly accurate approach to classifying high-dimensional data, such as the variation in apatite trace elements in different types

steel research international, EarlyView.The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...

VIEW, EarlyView.The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Harnessing energy metabolism for enhanced bone defect repair: Mechanisms and therapeutic strategies
VIEW, EarlyView.This review addresses the critical challenge of bone defect repair by focusing on the underexplored role of cellular energy metabolism. It synthesizes regulatory mechanisms in bone‐forming cells and sums up innovative strategies—leveraging cell derivatives, active factors, and biomimetic scaffolds—to modulate metabolism for enhanced regeneration.

Molecular structure and nickel‐binding capacity of Proteus mirabilis UreE
Acta Crystallographica Section D, EarlyView.This study presents a 2.0 Å resolution crystal structure and determined the nickel‐binding capacity of the P. mirabilis nickel chaperone UreE. UreE is essential for the delivery of nickel to the metalloenzyme urease, which is key for the ability of P. mirabilis to cause urinary‐tract infections.UreE is a nickel chaperone that is required for the safe ...

Integrative Zoology, EarlyView.This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Australian Endodontic Journal, EarlyView.ABSTRACT The sealing performance of endodontic sealers may be influenced by environmental factors such as pH and blood‐derived proteins. This in vitro study evaluated the effects of pH variation and protein contamination on calcium ion (Ca2+) release and push‐out bond strength (BS) of a calcium silicate‐based sealer (Bio‐C Sealer) and an epoxy resin ...
