DCLR-SF: distribution consistent label refinement and lighten similarity network fusion for multi-source domain-adaptive person re-identification
Unsupervised domain-adaptive person re-identification is challenging and has received much attention in recent years. Some previous works generate pseudo-labels by clustering algorithms to further optimize the...

BM-GMM: belief function-based Gaussian Markov model for image segmentation
The Gaussian mixture model (GMM) is an efficient statistical tool successfully used in the computer vision community. In this paper, we expand the classical GMM to a novel model based on Markov random field (M...

Formation of iron oxide–apatite deposits
Renewed economic interest in iron oxide–apatite (IOA) deposits — containing tens to hundreds of millions of tonnes of Fe and substantial amounts of rare earth elements, P, Co and V — has emerged to supply the ...

Open AccessPartitioning of REE between calcite and carbonatitic melt containing P, S, Si at 650–900 °C and 100 MPa
Carbonatites host some unique ore deposits, especially REE, and fractional crystallization might be a potentially powerful mechanism for control enrichment of carbonatitic magmas by these metals to economicall...

Quantum Simulation of Generalized Hardy’s Paradox and Corresponding Hardy’s Inequality via Quantum Programming
Hardy’s paradox can demonstrate the conflict between quantum mechanics and local realism. Experimental testing of Hardy’s paradox has been carried out, but it involved only a few qubits. We propose a simple bu...

Geological settings and metallogenesis of high-grade iron deposits in China
The predominant types of high-grade iron deposits in China include skarn, sedimentary metamorphic (banded iron-formation, BIF-type), continental/submarine volcanic-hosted and magmatic Fe-Ti-V oxide deposits. B...

Experimental evidence for a protracted enrichment of tungsten in evolving granitic melts: implications for scheelite mineralization
The solubility of scheelite in evolved granitic magmas (Qz-Ab-Or-An system with minor FeOtotal, TiO2, and CaO added) was studied experimentally at 200 MPa, 750–850 °C and relatively oxidizing condition (logfO2 = ...

Experimental study on the effects of H2O upon crystallization in the Lower and Critical Zones of the Bushveld Complex with an emphasis on chromitite formation
Mafic–ultramafic layered rocks of the Lower and Critical Zones of the Bushveld Complex are believed to have formed from a parental magma usually labelled B1 with SiO2 content at 55 wt.%, MgO at about 12 wt.% and ...

Demonstration of Quantum Nonlocality for Multi-Qubit Systems via Quantum Programming
Quantum nonlocality can be shown by measuring a quantum system containing multipartite entangled state. A key to quantum measurement is to find out what kinds of measurement settings are optimal. We design pro...

Open AccessImmiscible hydrous Fe–Ca–P melt and the origin of iron oxide-apatite ore deposits
The origin of iron oxide-apatite deposits is controversial. Silicate liquid immiscibility and separation of an iron-rich melt has been invoked, but Fe–Ca–P-rich and Si-poor melts similar in composition to the ...

The role of recycled oceanic crust in magmatism and metallogeny: Os–Sr–Nd isotopes, U–Pb geochronology and geochemistry of picritic dykes in the Panzhihua giant Fe–Ti oxide deposit, central Emeishan large igneous province, SW China
The picritic dykes occurring within fine-grained gabbro in the marginal zone and in the surrounding Proterozoic wall-rock marbles of the Panzhihua Fe–Ti oxide deposit closely correspond in bulk composition wit...

Dynamic analyses of steel-reinforced super high-strength concrete columns
The dynamic behaviors of steel-reinforced super high-strength concrete columns under seismic loading were studied with a series of experiments. Thirteen specimens, with concrete strengths ranging from 94.9 to ...
