For 30 years Disc Jockeys have been expressing their musical ideas with scratching. Unlike many other popular instruments, the equipment used for scratching is not built as one single unit, and it was not intended to be a musical instrument. This paper gives an overview of how DJs use their turntable, vinyl record and audio mixer in junction to produce scratch music. Their gestural input to the...

The epithelial surface is the site at which we first encounter pathogens. Two recent advances indicate that intraepithelial lymphocytes use specialized tools to help protect this surface.

Abstract Using molecular dynamics simulation, we investigate multiple scratching processes in which a tip moves through groove that has already been formed during previous scratch. We use conical indenter such the friction coefficient is independent of scratch depth. First, single to depth 4 nm compared with 2-cycle at 2 followed by second full nm. observe cycle shows smaller as long pre-formed...

Following Massimo Banzi’s comment that the Arduino development board might be seen as a means of ‘scratching your own itch’, this paper explores the concept of affect in relation to physical computing, and investigates the ways in which cybernetic and networked objects could be said to enact a series of process-philosophical and object-oriented tensions. In so doing it addresses the cultural sa...

Animals produce a variety of behaviors using a limited number of muscles and motor neurons. Rhythmic behaviors are often generated in basic form by networks of neurons within the central nervous system, or central pattern generators (CPGs). It is known from several invertebrates that different rhythmic behaviors involving the same muscles and motor neurons can be generated by a single CPG, mult...
