Additional supportive cells enclosing a prominent bundle of intermediate filaments provide the required mechanical strength [24]. Upon

In longitudinal sections, it appeared that type 1 and 2 adhesive gland cells were homogenously distributed. However, as the two

We also take a closer look at the influence of noise on lock-in measurements and state some simple rules for improving the signal-to-noise ratio.
