Embodiments of the invention relate to an image or raster compression method that includes receiving pixel data for a raster comprising a two dimensional array of pixels where each pixel is associated with a data value. The PCB includes a universal serial bus interface to be connected to an electronic device, a card interface to be connected to a card, a control chip, and a normally-closed switch coupled in a wire connecting a positive differential pin of the USB interface to the control chip. Other secondary embodiments of the gp41 proteins containing different modifications are also disclosed. In some embodiments, the method may also include combining the message with the MsgAC. The pivot member is rotatably coupled to the brake arm actuation assembly for pivoting the pivot member with respect to the longitudinal axis. Further, the invention provides a method for identifying agents which are useful for alleviating and inhibiting a lymphoproliferative disorders, as well as a method for identifying agents which are capable of inhibiting metastasis of lymphatic tumors in a mammal.
