A hernia repair implant includes a first layer for facing a body structure having a hernia defect so cover the defect while promoting tissue growth into the first layer from the body structure. A line is fit to multiple differential time values using a minimum delay principle. The receiving space is bounded on at least one side by the centrifugal mass arrangement, and at least one additional component of the drive unit is installed in the receiving space. Further, a physical configuration can be effectively simplified, and unnecessary power consumption can be reduced or prevented. Also disclosed are porous ceramic honeycomb structures comprising a ceramic body comprising at least one phase comprising a pseudobrookite-type crystal structure and at least one phase comprising zirconium tin titanate and methods of preparing a ceramic body comprising at least one phase comprising a pseudobrookite-type crystal structure and at least one phase comprising zirconium tin titanate.
