The structural stability and physical properties have been studied for carbon-(silicon-) doped La(13) clusters using DMOL method based on density-functional theory. Doped La(13) clusters prefer to be icosahedron. Substitutional doping with a carbon or silicon impurity makes some clusters closed electronic shell, especially in icosahedral isomers.(More)

We propose a novel interlayer potential, which is different from usual interatomic potentials. The interlayer potential represents the interaction between atomic layers in a layered material. Based on the Chen-Möbius inversion method in combination with ab initio calculations, the interlayer interactions are obtained for the face centered cubic (fcc) (111)(More)
All bedside monitors are prone to heterogeneity and mis-labeled data, yet each multimodal sample data contains different sets of multi-dimensional attributes. To reduce the incidence of false alarms in the Intensive Care Unit (ICU), a new interactive classifier was proposed. In the algorithm, case was represented with signal quality Indices(SQIs) and RR(More)
AIM To investigate the impact of adipose-derived mesenchymal stem cells (ADSCs) on cell viability and extracellular matrix (ECM) synthesis of corneal stromal cells (CSCs). METHODS ADSCs and CSCs were obtained from the corneas of New Zealand white rabbits and indirectly co-cultured in vitro. The proliferative capacity of CSCs in the different groups was(More)
Density functional theory involving generalized gradient approximation correlation functional is used to investigate the cluster series La @Si n (n=1-21). We find that the growth process of La @Si n (n=1-21) could be divided into three stages: First, La atom adheres to other Si atoms in the size range of 1<or=n<or=10; then, La atom is surrounded by Si atoms(More)
The propagation characteristics of the acoustic wave can usually be used to measure some thermal parameters by the way of non-contact. This paper proposes a new method to track the acoustic path by forward deploying triangles, which is based on the geometric acoustics and the Snell's law for moving medium in order to understand the impacts of the(More)
The present work develops a physically reliable procedure for building the embedded-atom-method (EAM) interatomic potentials for the metals with fcc, bcc and hcp structures. This is mainly based on Chen-Möbius lattice inversion (Chen et al 1997 Phys. Rev. E 55 R5) and first-principles calculations. Following Baskes (Baskes et al 2007 Phys. Rev. B 75(More)
