This settles a question raised by Morimoto [6], who showed that the (now known) classification of unknotting tunnels for 2–bridge knot...
متن کاملTransition from analogue-to-digital nuclear electronics for precise gamma radiation spectroscopy: advantages and limitations
In this paper, digital signal processing for precise gamma ray spectroscopy is presented. The basis of this system is a 14bit waveform digitizer which samples the output of pre-amplifier signals directly. The advantages and limitations of the digital spectrometer compared with analog spectrometer has been tested and analyzed from precise gamma ray spectroscopy point of view. The results shows t...

متن کاملForensic Analysis in the Wakayama Arsenic Case.
In the Wakayama poisoned curry incident in July 1998, 67 inhabitants were killed or injured by eating arsenic-laced curry at a neighborhood summer festival in Wakayama, a local city 400 km southwest of Tokyo. Heavy elements at ppm level, including arsenic, were discovered in the curry using SPring-8, a synchrotron radiation facility, as the tool for forensic analysis. This material evidence res...
