There is provided a balloon catheter system, enabling only a target site to be efficiently ablated, ensuring a balloon to be able to be brought into close contact with the target site in conformity to a shape of the target site. Specifically, resources that are missing because they have been reassigned from one logical partition within the system to another LPAR are tagged. The vertical structure is formed of a tunneling layer, a charge trapping layer, and a blocking layer sequentially stacked between the source region and the impurity region. The targeting keywords are ranked based at least in part on the quality scores when the bid associated with the second targeting keyword does exceed the bid associated with the first targeting keyword. Related methods and compositions are also described.
