APPLIED PHYSICS: Pick a Color

Applied Physics A

Applied Physics

A portable modular gas sensor for measuring the 13 C/ 12 C isotopic ratio in CO 2 with a precision of 0.8%o(±1σ) was developed for volcanic gas emission studies. This sensor employed a difference frequency generation (DFG)-based spectroscopic source operating at 4.35 µm (∼ 2300 cm −1) in combination with a dual-chamber gas absorption cell. Direct absorption spectroscopy using this specially des...

Physics at Large P G. Moortgat–pick

We summarize the results presented in the Physics at large p 2 T and Q 2 working group at the DIS'2002 Workshop. Higgs searches, precision measurements as well as searches for physics beyond the Standard Model at current and future experiments are reviewed.

Nominalization in Academic Writing: A Cross-disciplinary Investigation of Physics and Applied Linguistics Empirical Research Articles

The present study aimed to explore how nominalization is manifested in a sample of Physics and Applied Linguistics research articles (RAs), representing hard and soft sciences respectively. To this end, 60 RAs from discipline-related professional journals were randomly selected and analyzed in light of Halliday and Matthiessen’s (1999) taxonomy of nominalization. Comparing the normalized freque...

Alerting or Somnogenic Light: Pick Your Color

In mammals, light exerts pervasive effects on physiology and behavior in two ways: indirectly through clock synchronization and the phase adjustment of circadian rhythms, and directly through the promotion of alertness and sleep, respectively, in diurnal and nocturnal species. A recent report by Pilorz and colleagues describes an even more complex role for the acute effects of light. In mice, b...
