Abstract: Logical coverage areas are dynamically rearranged to meet the traffic needs of a wireless switching system. Further, the logical coverage areas do not have to be initially provisioned during deployment of the wireless switching system since the initial determination of the logical coverage areas is automatically performed. Once the logical coverage areas are established, the logical coverage areas adapt to the changing needs of the community of wireless handsets. A first embodiment allows the base stations to control the rearrangements, and a second embodiment allows a system wireless controller controlling the wireless switching system to control the rearrangements.

Title: Modulation of apoptosis
Inventor: KORSMEYER STANLEY J
IPC: C12N5/09
Filed: 1999-07-30
Abstract: Methods and compositions for modulating apoptosis in cells and patients are provided. One method comprises selecting a compound which affects the abilit y of a channel comprised of a member of the BCL-2 family to allow passage of cytochrome c, then administering the compound to the cell or patient. Anothe r method comprises selecting a compound which changes ion conductance properti es of the channel, then administering the compound to the cell or patient. Compounds which affect these channel characteristics are also provided. Additionally, methods for identifying apoptosis-modulating compounds using lipid bilayers are provided. One method involves contacting a compound of interest with a lipid bilayer which contains an ion-channel formed by an ant i- apoptotic or pro-apoptotic polypeptide of the BCL-2 family and assaying for changes in the ability of the pore to allow passage of cytochrome c. Changes  in ion conductance properties of the channel, including ion selectivity, single channel conductance and rectification are also useful characteristics  for identifying apoptosis-modulating compounds. A second method identifies compounds which can form ion channels in planar lipid bilayers and determine s the ability to allow passage of cytochrome c, the ion selectivity and the pH  dependence of such channels, where apoptosis modulating activity is predicte d based on comparing these channel forming characteristics with those of BCL-2  family members.
