Large acene molecules are common components of organic electronics. Appletonet al.show that embedding pyrazine units in acenes results in unexpected red-shifted optical transitions upon electronegative substitution, which may aid the design of acene-type materials for organic electronics applications.

Since its introduction to the US in 1999, the West Nile virus (WNV) has become endemic in the Americas. Here, the authors develop a model of WNV transmission dynamics between birds, mosquitoes and humans, which they integrate in conjunction with data assimilation methods, mosquito infection data and reported human cases in a New York county to show its utility for forecasting infection rates.

By analysing the smartphone data of 2,112,288 participants, in particular observing and comparing the activity of the same individual in two different environments, we find that increases in the walkability of environments result in increases in daily physical activity, providing evidence of the importance of the built environment on physical health.

The noise in a stochastic differential equation can be interpreted by Itô or by Stratonovich calculus, and which one to use has been a subject of discussion in statistical physics.
