The present invention relates to 5-heteroatom-substituted pyrazoles of the formula I: 1wherein the ring of the formula -A-, m, B, R1 through R5 are as defined in the specification, to pharmaceutical compositions containing them and to their medicinal use. More particularly, embodiments of the invention relate to a memory array testing architecture in which a memory array within a device under test is able to be tested at speeds substantially similar to those under typical operating conditions of the memory array without incurring significant die real estate and power penalties. The helical needle is advanced into the heart wall, and is used to stabilize the heart and to pass a purse string suture through the heart tissue. In a further embodiment, an interconnect assembly includes a flexible wiring layer having a plurality of first contact terminals and a semiconductor substrate which includes a plurality of second contact terminals.
