We observed that AC susceptibility of a weak random anisotropy magnet (weak RAM), amorphous NdGdFe, strongly depends on the excitation field, h 0 ; with increasing h 0 from 0.1 to 1 Oe, both Re χ 0 and Im χ 0 become several times larger, and the ra

Noninductive plasma current (Ip) start‐up experiments using RF power in the lower hybrid frequency range are being conducted on the TST‐2 spherical tokamak. The lower hybrid wave (LHW) has demonstrated efficient current drive in conventional toka

Plasma current start‐up experiments using the lower hybrid wave (LHW) excited by a new dielectric loaded waveguide array antenna are planned on TST‐2. The wave excitation efficiency of this antenna is investigated using a versatile FEM solver pac

We obtained sub-THz oscillation from resonant tunneling diode (RTD) oscillators with offset-fed slot antennas. The oscillation frequency without offset is about 350 GHz, whereas it increases to about 420-440 GHz with offset of 15 mum (60%) from the a

We propose resonant tunneling diode (RTD) oscillators with offset-fed slot antennas in THz and sub-THz range for high frequency and high output power oscillators at room temperature. We analyzed the dependence of the oscillation frequency and output

Limitations in the long-term results of medical treatment for mitral regurgitation are well recognized, but the advances in its surgical repair have produced good results. Therefore, early surgical intervention has been the focus of treatment in Euro

Body surface isopotential maps around early ventricular activation were investigated in 30 normal subjects by the use of the authors' signal-averaged body surface mapping system. The number of beats averaged was 96-154 (mean, 127). Two distinct patte

To examine the relation between ventricular depolarization and repolarization, body surface isopotential maps at the end of the QRS complex were studied in 32 normal subjects using a signal-averaged body surface mapping system. The number of beats av
