The concept of bounded expansion provides a robust way to capture sparse graph classes with interesting algorithmic properties. Most notably, every problem definable in first-order logic can be solved linear time on classes. First-order interpretations and transductions lead more general, dense that seem inherit many the nice properties their counterparts. In this paper, we show one encode grap...

The DCT (distal convoluted tubule) is the site of microregulation of water reabsorption and ion handling in the kidneys, which is mainly under the control of aldosterone. Aldosterone binds to and activates mineralocorticoid receptors, which ultimately lead to increased sodium reabsorption in the distal part of the nephron. Impairment of mineralocorticoid signal transduction results in resistanc...

Induced internalisation of functional proteins into cultured cells has become an important aspect in a rising number of in vitro and in vivo assays. The endo-lysosomal entrapment of the transduced proteins remains the major problem in all transduction protocols. In this study we compared the efficiency, cytotoxicity and protein targeting of different commercially available transduction reagents...

The paradigm of Computing by Observing, so far used for generating and accepting languages, is extended to transductions. We show that only string-rewriting rules of the form a→ b suffice to compute most rational and pushdown relations. Only pairs with empty left-hand side cause problems. Even non-pushdown relations can be computed, namely a test for prime numbers can be implemented.
