We read with interest the recent publication by MILLER and PEDERSEN [1] on determining the best way of expressing lung function impairment for prediction of mortality. The authors ranked the methods of expressing forced expiratory volume in 1 s (FEV1). It was concluded that the FEV1 quotient (Q) was the best predictor. We believe that this outcome is in need for some nuances. This ranking is, i...

Investment in energy research and development in the U.S. is declining despite calls for an enhancement of the nation’s capacity for innovation to address environmental, geopolitical, and macroeconomic concerns. We examine investments in research and development in the energy sector, and observe broad-based declines in funding since the mid-1990s. The large reductions in investment by the priva...

There’s a different way to go about the problem of finding all ways of writing n = x + y. Recall that in the Gaussian integers Z[i] we have an automorphism α 7→ ᾱ. Thus the function Nα = αᾱ = x + y is multiplicative. Thus our question is just to find all ways of writing n as a norm from the Gaussian integers. To answer this question we need to know a little about the structure of Z[i]. (Note th...

What r...
