This paper describes an experimental study of the enlargement of the vertical beam size observed in single beam operation at the KEKB LER.
This study used realistic representations of cloudy atmospheres to assess errors in solar flux estimates associated with 1D radiative transfer models. A scene construction algorithm, developed for the EarthCARE mission, was applied to CloudSat, CALIPSO and MODIS satellite data thus producing 3D cloudy atmospheres measuring 61 km wide by 14,000 km long at 1… (More)
Tumour necrosis factor (TNF)-alpha induces apoptosis in a human acute myeloid leukaemia cell line, Kasumi-1. To examine the role of protein phosphorylation in signal transduction of TNF-alpha-induced apoptosis, a variant cell line resistant to TNF-alpha was established by an intermittent challenge of Kasumi-1 cells with increasing concentrations of… (More)
Development of facile synthetic methods for various disubstituted pyrroles from pyrrolidine and 2-substituted 1-pyrrolines is reviewed based on our recent findings. Various 1,3-disubstituted pyrroles were synthesized by reaction of pyrrolidine and aldehyde heating without any catalyst. On the other hand, 2,3-disubstituted pyrroles were synthesized from… (More)
Crab cavities have been installed in the KEKB B– Factory rings to compensate the crossing angle at the collision point and thus increase luminosity. The beam operation with crab crossing has been done since February 2007. (IP). Although there are a lot of merits in the crossing angle scheme, the beam-beam performance may degrade. The design of KEKB… (More)
Crab cavities have been installed in the KEKB B– Factory rings to compensate the crossing angle at the collision point and thus increase luminosity. The beam operation with crab crossing has been done since February 2007. This is the first experience with such cavities in colliders or storage rings. The crab cavities have been working without serious… (More)
