L-systems are parallel generative grammars, used to model plant development, with the results usually interpreted graphically. Music can also be represented by grammars, and it is possible to interpret L-systems musically. We search for simultaneous ‘pleasing’ graphical and musical renderings of L-systems.

We present sensitivity measurements of the EVLA at L-band between 1 and 2 GHz to assess the impact of the receivers with the new thermal gap assembly. Our on-the-sky test results are consistent with lab measurements, and show that the sensitivity improves by an average value of ∼7% in the frequency range 1–1.55 GHz, and degrades by an average value of ∼3% in the frequency range 1.55–2 GHz. The ...
