Collective Josephson vortex dynamics in a finite number of intrinsic Josephson junctions

, 2006
We report the experimental confirmation of the collective transverse plasma modes excited by the Josephson vortex lattice in stacks of intrinsic Josephson junctions in Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+x}$ single crystals.

Study of Dual-Stage PDC Bit Flow Field Based on Discrete Phase Model

Shiyou jixie, 2019
To address the interferes of the flowback drilling fluid from the pilot bit of the dual-stage PDC bit with the flow field of the reaming bit, a new dual-stage bit hydraulic structure is formed by adding the inter-stage nozzle on the flow distribution ...
