RE: REempower and REcycle

This paper briefl y presents two concepts of “RE” (1) re-empowering individuals using personal mobile technology reconstructed as measurement instruments and (2) re-cycle as a design constraint for extending a product’s usable lifetime. In the fi rst example we demonstrate the integration of simple low-cost, low-power air quality sensors attached to a mobile phone. In the re-cycle case, we demo...

First remodel, then recycle

M ultivesicular bodies (MVBs) are specialized endosomes that promote the degradation of membrane proteins by delivering them to lysosomes. This process is regulated by a series of endosomal sorting complexes required for transport (ESCRTs) (1). The ESCRT-0,-I, and-II complexes sequester ubiquitinated membrane proteins and recruit the ESCRT-III complex to drive the invagination and release of ca...

Why endosomes recycle GPCRs

Bowman et al. provide a novel explanation for why activated G protein–coupled receptors (GPCRs) migrate from the cell surface to the endosomes (1). The study indicates that GPCRs that have moved to certain locations on endosomes activate specifi c genes—and thus presumably induce different cellular responses. GPCRs help us perceive our surroundings, control our blood pressure, mobilize our immu...

Recycle of Random Sequences

The correlation between a random sequence and its transformed sequences is studied. In the case of a permutation operation or, in other word, the shuffling operation, it is shown that the correlation can be so small that the sequences can be regarded as independent random sequences. The applications to the Monte Carlo simulations are also given. This method is especially useful in the Ising Mon...
