OBJECTIVE To investigate the effects of valacyclovir and prednisolone in comparison with those of placebo and prednisolone for the treatment of Bell's palsy, excluding zoster sine herpete. STUDY DESIGN Prospective, multicenter, randomized placebo-controlled study. SETTING Six academic tertiary referral centers. PATIENTS Ultimately, 221 patients with(More)
Certain types of satellite failures, such as broadcast ephemeris messages that do not correspond to true satellite locations, can be difficult to detect by a Local Area Augmentation System (LAAS) ground facility (LGF) because satellites are observed from reference antennas that are very close together. Although ephemeris failures large enough to threaten(More)
Motion JPEG2000 has been developed as a new video coding standard for motion pictures, utilizing the still image coding standard JPEG2000. Motion JPEG2000 specifies a normative bitstream syntax that the decoder must recognize and allows flexible selection of detailed coding parameters at the encoder. The compression performance largely depends, therefore,(More)
AIM   Non-hepatitis B virus/non-hepatitis C virus-related hepatocellular carcinoma (NBNC-HCC) is often detected at an advanced stage, and the pathology associated with the staging of NBNC-HCC remains unclear. Data mining is a set of statistical techniques which uncovers interactions and meaningful patterns of factors from a large data collection. The aims(More)
OBJECTIVE To investigate the therapeutic effects of acyclovir and prednisolone in relation to the timing of treatment in Bell's palsy. STUDY DESIGN This was a retrospective study of 480 Bell's palsy patients who were treated with oral acyclovir and prednisolone (94 cases) or prednisolone alone (386 cases). PATIENTS Patients met the after criteria: (1)(More)
To realize practical orbital servicing missions in the 21" century, we have developed a new system concept for an orbital servicing vehicle named Hyper-OSV (Orbital Servicing Vehicle), which has higher speed manipulation capability and larger operation area than OSVs that were proposed in the 1990's. The main feature of Hyper-OSV (HOSV) is the separation of(More)
BACKGROUND The incidence of hepatocellular carcinoma (HCC) in Japan has still been increasing. The aim of the present study was to analyze the epidemiological trend of HCC in the western area of Japan, Kyushu. MATERIAL/METHODS A total of 10,010 patients with HCC diagnosed between 1996 and 2008 in the Liver Cancer study group of Kyushu (LCSK), were(More)
The problem of planning safe kinematic approach trajectories for robotic capture of an uncontrolled rotating satellite is addressed, and two methods of trajectory planning are presented. The first method uses equations of orbital mechanics to plan a passive fly-by approach path for certain conditions of target satellite motion. The second method uses(More)
