Amplitude enhancement of short period GPS-TEC oscillations over rainfall area Open
Correlation between rainfall and short period GPS-TEC (total electron content) variations are investigated by using the precipitation data obtained on the ground and estimated from satellite observations (JAXA/GSMaP) as a proxy of lower at…

Global distribution of magnetic ripples and electron density fluctuations as observed by the Swarm satellites on the dayside and their relation to the rainfall estimated by the GSMaP Open
In mid- and low-latitude ionospheric F-region on the dayside, magnetic field and electron density (Ne) fluctuations with amplitude smaller than a few nT and 1–2% of Ne, respectively, are commonly observed. Their spatial scale along satelli…

A Facile Approach to the Synthesis of 3-Acylisoxazole Derivatives with Reusable Solid Acid Catalysts Open
Nitrile oxides were formed from α-nitro ketones using silica gel-supported sodium hydrogen sulfate (NaHSO4/SiO2) or Amberlyst 15 as solid acid catalyst, and then the corresponding 3-acylisoxaszoles were obtained by reacting with alkynes vi…

Indirubin 3′-oxime inhibits anticancer agent-induced YB-1 nuclear translocation in HepG2 human hepatocellular carcinoma cells Open
Hepatocellular carcinoma (HCC) is a disease with poor prognosis. Nuclear accumulation of YB-1 is closely related to the malignancy of HCC. Treatment with anticancer agents often induces translocation of YB-1 from cytoplasm to nucleus and a…
