阿尔都塞基于对马克思哲学存在认识论断裂的理论判断，提出了一种马克思主义的反人道主义立场，并以矛盾的多元决定论为依托，从根本上动摇了以人道主义为基础建立一种马克思主义伦理学的合法性，由此为在历史唯物主义的科学性上建立起一种非意识形态的伦理学提供了理论视域。这种伦理学完全超出了既往西方哲学史框架下对伦理学的认知和印象，并具有一种历史唯物主义的科学特征。

Orthogonal isometric projection for face recognition

引用

The Journal of China Universities of Posts and Telecommunications 2011年第1期18卷 91-97,128页

作者： LU Guan-ming ZUO Jia-kuo College of Communication and Information Engineering Nanjing University of Posts and Telecommunications Nanjing 210003 China

Isometric projection （IsoProjection） is a linear dimensionality reduction method, which explicitly takes into account the manifold structure embedded in the data. However, IsoProjection is non-orthogonal, which makes it extremely sensitive to the dimensions of reduced space and difficult to estimate the intrinsic dimensionality. The non-ortbogonality also distorts the metric structure embedded in the data. This paper proposes a new method called orthogonal isometric projection （O-IsoProjection）, which shares the same linear character as IsoProjection and overcomes the metric distortion problem of IsoProjection. Similar to IsoProjection, O-lsoProjection firstly constructs an adjacency graph which can reflect the manifold structure embedded in the data and the class relationship between the sample points of face space, and then obtains the projections by preserving such a graph structure. Different from IsoProjection, O-IsoProjection requires the basis vectors to be orthogonal, and the orthogonal basis vectors can be calculated by iterative way. Experimental results on ORL and Yale databases show that O-lsoProjection has better recognition rate for face recognition than Eigenface, Fisherface and IsoProjection.

Understanding the defense mechanisms of the host of an organism is important for infection *** previous studies,we demonstrated that interferon-a(IFN-a),but not IL-12,was produced by human peripheral blood mononuclear cells infected with varicella-zoster virus(VZV).Here,we investigated what kind of cell(s)and which signal molecule(s)are involved in IFN-a *** cell isolation and ELISA,we found that plasmacytoid dendritic cells(pDCs)were responsible for IFN-a production during VZV *** also found that Toll-like receptor 9(TLR9)was involved in VZV-induced IFN-a production because inhibitory CpG oligodeoxynucleotide inhibited IFN-a ***-inactivated VZV-induced IFN-a production was lower than that of active VZV,indicating another TLR9-independent *** studies demonstrated that double-stranded RNA-dependent protein kinase,but not DNA-dependent protein kinase was involved in VZV-induced IFN-a ***,these results suggest that pDCs play an important role in IFN-a production during VZV infection through TLR9-dependent and-independent pathways.
