Emulating a packet reorder condition in a network includes maintaining a counter variable to count packets sent out since the most recent reordered packet. The score is computed by calculating a time decay factor for each product category. A second coupler is adapted for releasably coupling the first and second bars together in a spaced relationship to each other. Each of the front and back regions includes a pair of ear portions extending in substantially opposite lateral directions with respect to the longitudinal plane. The invention also related to compositions which comprise these compounds, and methods of using them to treat cancer in mammals. The repositioning of the control panel device allows an operator to clearly view a display on the device from any work area of the mailing machine.
