    On almost complex curves and Hopf hypersurfaces in the nearly Kähler six-sphere

    We study the almost complex curves and Hopf hypersurfaces in the nearly Kähler S 6(1), and their relations. For Hopf hypersurfaces, we give a classification theorem under some additional condition...

    Multimodel Music Emotion Recognition Using Unsupervised Deep Neural Networks

    In most studies on multimodal music emotion recognition, different modalities are generally combined in a simple way and used for supervised training. The improvement of the experiment results illustrates the ...

    Scalar curvatures in almost Hermitian geometry and some applications

    On an almost Hermitian manifold, there are two Hermitian scalar curvatures associated with a canonical Hermitian connection. In this paper, two explicit formulas on these two scalar curvatures are obtained in ...

    The prescribed Gauduchon scalar curvature problem in almost Hermitian geometry

    In this paper, we consider the prescribed Gauduchon scalar curvature problem on almost Hermitian manifolds. By deducing the expression of the Gauduchon scalar curvature under the conformal variation, we reduce...

    Analysis of the Limiting Spectral Distribution of Large-dimensional General Information-Plus-Noise-Type Matrices

    In this paper, we derive the analytical behavior of the limiting spectral distribution of non-central covariance matrices of the “general information-plus-noise" type, as studied in Zhou (JTP 36:1203–1226, 202...
