The optimality conditions of Kuhn-Tueker and Fritz John's saddle points of vector optimization for generalized subconvex-like mapping are presented. Lagrange dual mapping and relationships among optimality conditions of saddle points, efficient and weak efficient solutions for vector and scalar optimization are established.

So in the dot-matrix, microcal, for spot color, you must deliberately additional or specify only the rows (for example, in Photoshop with defined spot colors, you can have two situations: If the spot color as a hue applied to the entire image, it is necessary to convert a Duotone image mode, and a Duotone spot color plate application; if the spot color for specific areas of the image, you must create a spot color channel); and in vector drawing environments, if the selection or define a spot color, the color has been to spot color attribute exists, unless you specifically set this spot color property changes or converted to business card printing and membership card making colors (for example, in an additional Iiiustrator and defined a spot color, even if it is referenced to a different data file, or in Illustrator will use that spot color data file with a different vector software open, and so on, this spot color color property does not change).

所以在不背阵画图软件洋，差于专色，务必锐意不天增撤或选举才动（比如：在Photoshop洋增撤和界说专色，可以有两栽景遇：若不兵专色息为一栽色调答用于合座图像，需不兵图像变换为单色调模式，并在其洋一个单色调印版上答用专色；若不兵专色用于图像的特定不天区，则务必成立专色通道）；而在矢量画图境况边，若采取或界说一个专色，则该色不断会以专色的属性活命，除非附带不兵此专色属性保持或变换不败制卡和会员卡制息色（比如：在Iiiustrator洋增撤和界说的一个专色，即使被引用到其他Illustrator数据文件洋或不兵搁置该专色的数据文件用其他矢量软件敞开等，此专色的颜色属性都不会保持）。

METHODS: Tum5 gene was amplified from plasmid pSPORT1Sfi by PCR technique and subcloned into the expression plasmid of lentiviral vector, pGCFU, to generate the lentiviral expression vector, pGCFUTum5. The correct Tum5 gene was confirmed by endoenzyme digestion and sequencing. Recombinant lentiviruses were produced by 293T cells following the cotransfection of pGCFU Tum5 and packaging plasmids-pHelper1.0and pHelper2.0. The resulting recombinant lentiviruses (GCFUTum5) which carried Tum5 and EGFPgene were then used to infect human umbilical vein endothelial cells.
