Rich functionalities of transition-metal oxides and their interfaces bear an enormous technological potential. Its realization in practical devices requires, however, a significant improvement yet relatively low electron mobility oxide materials. Recently, boost about two orders magnitude has been demonstrated at the spinel/perovskite {\gamma}-Al2O3/SrTiO3 interface compared to paradigm perovsk...

Motivated by the construction of new examples of Artin-Schelter regular algebras of global dimension four, J.J.Zhang and J.Zhang (2008) introduced an algebra extension AP [y1, y2;σ, δ, τ ] of A, which they called a double Ore extension. This construction seems to be similar to that of a two-step iterated Ore extension over A. The aim of this paper is to describe those double Ore extensions whic...

According to the publication by US Minerals Survey in 1999, the total reserve of manganese ore in the world is 0.66 billion tons. See Table 1.

This paper focuses on the scientific problem of quantitative mineralization prediction at large depth in Zaozigou gold deposit, west Qinling, China. Five geological and geochemical indicators are used to establish model. Machine learning Deep algorithms employed for 3D Mineral Prospectivity Mapping (MPM). Especially, Student Teacher Ore-induced Anomaly Detection (STOAD) model is proposed based ...

Purpose. Study on the processes contributing to formation of pyrite-polymetallic mineralization in Rudny Altai, development recommendations for directions further research. Methodology. Analysis literature and fund materials, field studies within known ore fields deposits, sampling laboratory studies: spectral analysis, chemical composition host rocks (ISP-MS Agilent 7500cx), study mineral main...

Hyperspectral anomaly detection (AD) task is a typical binary classification problem, and utilizing background prior knowledge key technique to solving such problems. The two most commonly used priors for hyperspectral images are low-rank local smooth properties. Most traditional matrix-based methods use regularizations model these types of integrate them into one model, which makes unable maxi...

Knowledge about the consequences of Arctic warming for marine biogeography remains limited. Mytilus mussels play a key ecological role in the littoral zone, and they are expected to be sensitive to climate change. Here we used a space-for-time approach as a first attempt to infer the coupling between climate warming and population structure and abundance of intertidal mussels along a latitudina...
