Synaptic depression at conventional synapses is usually caused by strong or prolonged stimuli, like tetanic bursts of afferent fiber discharge at high frequencies. In this issue of Neuron, Dunn and Rieke report that, in the retina, even the weakest stimuli, single photons, can lead to synaptic depression at ribbon-type synapses and adaptation of neuronal output to ambient light levels.

This paper describes a series of mathematical functions implemented by the author in the commercial algorithmic software language ArtWonk, written by John Dunn, which are offered with that language as resources for composers. It gives a history of the development of the functions, with an emphasis on how I developed them for use in my compositions.

In this work we study an abstract formulation of a problem posed by J.M. Dunn, T.J. Hagge et al. about the inclusion of varieties generated by the modular ortholattice of subspaces of C. We shall prove that, this abstract formulation is equivalent to the direct irreducibility for atomic complete modular ortholattices.

Byers and Dunn (Reports, 9 November 2012, p. 802) claimed that predation on offspring reduced the potential for sexual selection in pronghorn. We argue that the potential for sexual selection is not affected by random offspring mortality when relative reproductive success is considered and increases when measured with the opportunity for selection, a metric that describes the potential for sele...
