Appl. No.:

10/974265

Jun Lin - Forest Hills NY, US

Assignee:

Cornell Research Foundation, Inc. - Ithaca NY

International Classification:

C12N 15/00
C12N 5/02

US Classification:

4353201, 435325

Abstract:

The present invention relates to a method of isolating stem cells from a mixed population of different cell types. This method involves selecting a promoter which functions only in said stem cells and not in the other cell types. The promoter can have a nucleotide sequence selected from the group consisting of SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, and SEQ ID NO: 8. A nucleic acid molecule encoding a marker protein under control of said promoter is introduced into all cell types of said mixed population and only the stem cells, but not the other cell types, within said mixed population are allowed to express said marker protein. The cells of said mixed population of cell types that are expressing the marker protein, which are restricted to the stem cells are identified and separated from the mixed population, where the separated cells are restricted to the stem cells. The promoter, nucleic acid constructs comprising it, and the resulting stem cells are also disclosed. The nucleic constructs can be incorporated in transgenic animals in order to monitor stem cell movement.

International Classification:

H04W 4/00

US Classification:

4554351

Abstract:

Systems and methods are presented to support operation of a multiple subscriber identity module (SIM) device. A first SIM may perform a data transfer or voice call. During the first SIM's data transfer or voice call, transition times are identified to transition communication resources to a second SIM for use in performing a registration update communication with a network controller that supports the second SIM. The registration update communication may include a periodic location update, a periodic routing update, or a periodic tracking update. The multiple SIM device may identify the transition time by obtaining periodic registration timing information from the network controller, configuring a periodic registration timer based on the periodic registration timing information, and setting the transition time as an expiration time of the periodic registration timer.

International Classification:

H04W 4/00

US Classification:

455418

Abstract:

Systems and methods are presented to support operation of a multiple subscriber identity module (SIM) device. A timing conflict may exist when a scheduled high priority communication of a first SIM overlaps with a scheduled paging monitoring activity for a second SIM. The multiple SIM device may preempt transitioning communication resources to the second SIM when the first SIM executes high priority communications. Or, the multiple SIM device may execute a rescheduling action to resolve the timing conflict. The high priority communication of the first SIM may be rescheduled. Alternatively, normal priority paging monitoring actions may be rescheduled to resolve the timing conflict.

International Classification:

H04W 68/00

US Classification:

455434

Abstract:

A wireless communication device includes a single baseband processor and RF chain for servicing a first and second SIM. Each of the SIMs connects to a different network, and one may be used for one data type while the other is used for another data type. In order to track the connectivity of an inactive first SIM, a controller periodically interrupts service to the second SIM. During its connection, the first SIM monitors the connection to its network. A triggering mechanism and trigger threshold define when a switch to a new cell is needed. The device receives the mechanism and threshold from the network and calculates a modified threshold and/or mechanism is order to reduce a number of potentially missed calls.
