APPLIED PHYSICS: Warming Up Neuroimaging

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...

Warming-up in USRPT

Some activities for in-pool warm-ups have been evaluated. An historically important study was conducted by Carlile (1956). It was shown that the passive activity of tolerating a hot shower for as long as possible prior to performing a maximal 55-yard swim produced improved performances in all subjects significantly more than in a control group (no hot showers). A passive warm-up is possible if ...

A simple technique is explored to determine the temporal photo-response, s, of individual semiconducting SiC and Si nanowires (NWs), with a high time resolution. Laser-assisted field emission (LAFE) from the NWs is first shown to be highly sensitive to continuous laser illumination. Pulsed illumination is then combined with measurements of the total energy distributions to determine s which wer...
