A Modified Embedded-Atom Potential for Fe-Cr-Si Alloys

The Journal of Physical Chemistry C, 2021
We developed a modified embedded atom method (MEAM) potential for Fe-Cr-Si ternary systems. These alloys have superior corrosion and crack resistance, making them candidate materials for several engineering applications such as accident-tolerant fuel cladding.

Embeddings for 3-dimensional CR-manifolds

2000
We consider the problem of projectively embedding strictly pseudoconcave surfaces, X_ containing a positive divisor, Z and affinely embedding its 3-dimensional, strictly pseudoconvex boundary, \( M = - bX\_ \) We show that embeddability of M in affine space is equivalent to the embeddability of X_ or of appropriate neighborhoods of Z inside X_ in ...

Laufer's vanishing theorem for embedded CR manifolds

Mathematische Zeitschrift, 2002
It was proved by Laufer that the Dolbeault cohomology groups are either zero or infinite dimensional for any open subset of a Stein manifold. In this paper, the author proves an analogue for CR manifolds. Namely, he shows that the cohomology groups of the Cauchy-Riemann complexes are either zero or infinite dimensional for a sufficiently small open ...

Pdes Associated to the CR Embedding Theorem

1999
The purpose of the present article is to explain a construction of a complex tubular neighborhood of a strongly pseudoconvex CR manifold, say M, using the CR geometry of M. The outline of the results obtained prior to 1996 are published in [11]–[14]. For the sake of the convenience of the readers, we will give the description from the beginning.

CR-TransR: A Knowledge Graph Embedding Model for Cultural Domain

Journal on Computing and Cultural Heritage
As a combination of information computing technology and the cultural field, cultural computing is gaining more attention. The knowledge graph is also gradually applied as a particular data structure in the cultural area. Based on the domain knowledge graph data of the Beijing Municipal Social Science Project “Mining and Utilization of Cultural ...

Magnetic Properties and Stability of Quasi-One-Dimensional Cr Chains Embedded in (Zn,Cr)Te

Applied Physics Express, 2013
The controlled formation of quasi-one-dimensional (1D) chainlike structures of transition metal impurities in diluted magnetic semiconductors has been proposed to increase their Curie temperatures. We investigate the stability and magnetism of several quasi-1D Cr chains embedded in the prototype system (Zn,Cr)Te by first-principles calculations.

Role of Embedded Clustering in Dilute Magnetic Semiconductors: Cr Doped GaN

Physical Review Letters, 2005
Results of extensive density-functional studies provide direct evidence that Cr atoms in Cr:GaN have a strong tendency to form embedded clusters, occupying Ga sites. Significantly, for larger than 2-Cr-atom clusters, states containing antiferromagnetic coupling with net spin in the range 0.06-1.47 muB/Cr are favored.

Bare conical nanopore embedded in polymer membrane for Cr(III) sensing

Talanta, 2015
In this article, we propose a nanopore-based approach to detect metal ions without any external functionalization. In detection of the biologically and environmentally relevant Cr(3+) ion as a prototypical example to prove our strategy, both selectivity and sensitivity were individually achieved.

Versal embeddings of compact 3-pseudoconcave CR submanifolds

Mathematische Zeitschrift, 2004
Let \(M\) be a generic CR submanifold in a complex manifold \(G\) and denote by \(T'M = T^{\mathbb C}M \cap T' G\) the holomorphic tangent bundle, which defines the CR structure of \(M\). If we fix an Hermitian metric on \(G\), the Levi form of \(M\) in the direction of a vector \(v \in N_xM = T_xM \cap \text{Re}(T'_xM \oplus \overline{T'_xM})^\perp \)
