Full size image Our findings also hold when we control the simplicial complex and random hypergraph to have the same number of connections (see Supplementary Fig. S1) and for simplicial complexes obtained by filling empty triangles in random hypergraphs33, as shown in Supplementary Fig. S2. We ...
The vector optimization problem for the set-valued function is considered, where X0 is a subset of a real Banach space X and Y is a real Banach space with ... Ginchev,Ivan - 《Journal of Statistics & Management Systems》 被引量: 27发表: 2002年 Fast Higher-Order MR Image Reconstruction...
Color image restorationColor image decompositionIn this paper, a vector total fractional-order variation (VTV-beta) is proposed. Then, VTV-beta model and G(beta)(Omega) model are proposed for color image denoising and decomposition, respectively. Some properties of the VTV-beta are investigated ...
According to (1.16) the exponent ηq0 depends on the modulus of elasticity of the crystal, the reciprocal lattice vector, and the temperature. The elastic energy of an isotropic two-dimensional crystal is given by the formula (Landau and Lifshitz, 1986) (1.17)H=∫dxdyλ2uxx+uyy2+μuxx2...

Hyperstreamlines are a generalization to second order tensor fields of the conventional streamlines used in vector field visualization. As opposed to point icons commonly used in visualizing tensor fields, hyperstreamlines form a continuous representation of the complete tensor information along a three...
then, using the set of eigenvectors corresponding to the sub-band centered at ν = π, the nested Wilson loop operator \(\tilde{W}\) along the G2 vector is defined as $${\tilde{W}}_{({k}_{2}+2\pi )\leftarrow ({k}_{2})}=\mathop{{\mathrm{lim}}}\limits_{N\to \infty ...
47, the projection operators of conduction and valence bands can be expressed by a unit vector lying on a unit five-sphere S5, which is suitable for a 3D BBH model with specific parameters. In this way, the gauge group of the intra-band Berry connection and Berry curvature for BBH model...
