At the cellular level, cardiac pacemaking which sets the rate and rhythm of the heartbeat is produced by the slow diastolic depolarization. Several ion channels contribute to this pacemaker depolarization, including T-type and L-type calcium currents. To evaluate the molecular basis of the currents involved, we investigated the cellular distribution of(More)
Heterogeneous geographic databases contain multiple views of the same geographic objects at different levels of spatial resolution which must be consistent with each other. This paper develops a formal method of assessing consistency of topological relations in R 2 at a high level of abstraction, over complexly structured spatial objects that form networks.(More)
