Experimental evidence for a multicritical point in the magnetic phase diagram for the mixed state of clean untwinned YBa2Cu3O7
(1993)We report on transport measurements in fields up to 16 T in clean, untwinned single crystals of YBa2Cu3O7 which indicate that there is a critical end point for first-order melting in the H-T phase diagram in the mixed state ...

Extension and application of an algorithm for systematic identification of weak coupling and partitions in dynamic system models
(2009)This paper reviews and extends a technique to detect weak coupling (one-way coupling or complete decoupling) among elements of a dynamic system model, and to partition and reduce models in which weak coupling is found. The ...
