Recent Topics in Ophthalmological Practice in Japan

Recent topics in NMR imaging and MRI.

NMR and NMR imaging (MRI) are finding increasing use not only in the clinical and medical fields, but also in material, physicochemical, biological, geological, industrial and environmental applications. This short review is limited to two topics: (i) new techniques and pulse sequences and their application to non-clinical fields that may have clinical application; and (ii) new trends in MR con...

Recent Topics in Power Management Circuits

This paper summarizes recent research at the author’s laboratory into power management circuitry, including: (1) Envelope-tracking power supplies for base station power amplifiers, (2) Digital PWM generator circuitry, (3) Spreadspectrum clocking for EMI reduction in digitally-controlled power supplies, (4) High-efficiency coupled-inductor DC-DC converters with fast response and low ripple, and ...

Recent Ground Based GPS Meteorology Developments for SuomiNet

Over the past 10 years significant progress has been made in atmospheric sensing with GPS. Both spacebased atmospheric sounding and ground-based measurements of integrated delay due to the troposphere have shown promise for meteorological applications. Now the focus is shifting from developing and validating the sensing technology towards applying it to weather forecasting. This paper will focu...
