Recently, it has become clear that there are two clades in Liobagrus reinii, which can reasonably be judged as separate species. In this study, we attempted to clarify the differences in distribution and habitat of the two clades of Liobagrus reinii in the Gonokawa and the Ota River Systems by using environmental DNA analysis metabarcoding. In the Gonokawa River System, the number of the present sites and environmental DNA concentrations of clade 1 were higher than those of clade 2. In the Ota River System, the number of the present sites and environmental DNA concentrations of clade 2 were higher than those of clade 1. In both river systems, clade 1 tended to be found at lower elevations and clade 2 at higher elevations.

In The Two Homelands by Yamasaki Toyoko, there is a detailed description of the International Military Tribunal for the Far East, and this study attempts to examine how the Evidence Phase by the USSR, on October 8, 1947, is reproduced in the work. The full text of the evidence is available in The Stenographic Record of International Military Tribunal for the Far East (1968, Yushodo Shoten). In this research, comparing the original evidence in the Stenographic Record and the text reproduced in The Two Homelands revealed that much of it was quoted extensively.

The aim of this study is to compare the heart rate (HR) derived from electrocardiogram (ECG) with the pulse rate (PR) derivedfrom the green light ear photo-plethysmogram (PPG) using an earphone. We developed a compact device that the PPG sensorcomprising a green LED and phototransistor was embedded in the earphone. The weight of device was 8.8 g. In 10 subjects,simultaneous measurements of ECG, and green light (525 nm) PPG from the front of tragus were made at the following treadmillspeeds: 0, 2, 4, 6, 8 km/h. During walking (2, 4 km/h), the results showed that the PR derived from the green light PPG from theear significantly related to HR derived from ECG (r = 0.98). In addition, the limit of agreement in Bland-Altman plots betweenthese indices were ± 3.95 (1.96 SD) bpm. In conclusion, these findings suggest that the green light ear PPG using earphone mightbe practical measurement for monitoring HR during walking.

This paper summarizes several robot programming approaches and presents a direct teaching method for robot programming of manipulators. A human operator wearing a head-mounted display and hand-held controllers manipulates a spherical marker in the computational space to determine a desired position of the manipulator. A depth camera attached to the manipulator acquires a point cloud of the surroundings of the manipulator to construct the scanned map in the computational space. The desired posture of the manipulator can be found by solving an inverse kinematics problem.
