This paper focuses on the surface contamination control of slightly contaminated property after the Fukushima nuclear accident. The operational level for the unconditional release of contaminated properties is calculated in counts per minute (cpm) to enable the use of a typical Geiger-Muller (GM) survey meter with a 50-mm bore, on the basis of the surficial clearance level of 10 Bq cm(-2) for (...

Feeling the beat and meter is fundamental to the experience of music. However, how these periodicities are represented in the brain remains largely unknown. Here, we test whether this function emerges from the entrainment of neurons resonating to the beat and meter. We recorded the electroencephalogram while participants listened to a musical beat and imagined a binary or a ternary meter on thi...

Abstract The prevalence of inexpensive global navigation satellite system (GNSS) chips that facilitate the performance carrier phase measurements has provided hardware can be used as foundation for implementing precise point positioning (PPP) low-cost smartphones. However, because atmospheric delays and high measurement noise associated with low-quality patch antennae, convergence time...
