Journal ArticleDOI
TL;DR: This work demonstrates bright silicon vacancy (SiV(-)) centres in low-strain bulk diamond, which show spectral overlap of up to 91% and nearly transform-limited excitation linewidths, the first time that distinct single-photon emitters in the solid state have shown intrinsically identical spectral properties.
Abstract: In quantum optical technologies, identical emitters of indistinguishable single photons are difficult to realize due to the inherent dissimilarity of each emitting device Here, Rogers et al demonstrate a solid-state uniform single-photon source, which does not require external tuning of optical properties

TL;DR: Ikeda et al. as discussed by the authors showed that the combined action of iron uptake and a key transcription factor involved in mitochondrial biogenesis are required for the proper functioning of these cells and that in cases of increased bone loss, iron chelation may be beneficial by inhibiting these cells.
Abstract: Bone is resorbed by osteoclasts, and too much activity by these cells leads to disease, such as osteoporosis. Here Kyoji Ikeda and colleagues show that the combined action of iron uptake and a key transcription factor involved in mitochondrial biogenesis are required for the proper functioning of these cells and that in cases of increased bone loss, iron chelation may be beneficial by inhibiting these cells.

TL;DR: The results showed the amplitudes of EMG were reduced significantly, the operator was able to swing the leg lighter by reducing the inertia around knee, and the strain of knee in foot-grounding could be alleviated by adding the stiffness to joint.
Abstract: This paper describes the power assist control for walking aid based on EMG and impedance adjustment with HAL-3 we have developed. Virtual torque derived from EMG is adopted as a basic control method, and the motion assist control as to operator's intention can be realized by this method. And we suggest the impedance adjustment around knee joint for more effective power assist control. Experiments for simple motion and walking motion were performed to verify the proposed approach, with impedance parameters found by RLS (recursive least square) method. The evaluation of assisted motion was done by a calculation based on EMG in nearly proportion to the operator's muscle force. The results showed the amplitudes of EMG were reduced significantly, the operator was able to swing the leg lighter by reducing the inertia around knee, and the strain of knee in foot-grounding could be alleviated by adding the stiffness to joint.
