It is shown that both R-mode and L-mode waves can efficiently scatter energetic (10keV~100keV) electrons and protons and cause precipitation loss at L = 4, indicating that perhaps wave–particle interaction is a serious candidate for the ring current decay. 展开 关键词:...
Internal solitary waves (ISWs) are frequently observed in the Sulu Sea and the Celebes Sea. Based on MODIS and VIIRS optical remote sensing images from October 2016 to September 2019, the characteristics of ISWs in the areas were studied. The spatial dis
Although the smoothing effect from damping or heat diffusion alone can prevent the breaking of smooth waves of small amplitude, the combined effect of damping and heat diffusion may still not be strong enough to prevent the formation of singularities in large smooth solutions, as shown in Chen an...
Metasurfaces have promising potential to revolutionize a variety of photonic and electronic device technologies. However, metasurfaces that can simultaneously and independently control all electromagnetics (EM) waves’ properties, including amplitude, ph
In late 2022, SARS-CoV-2 Omicron subvariants have become highly diversified, and XBB is spreading rapidly around the world. Our phylogenetic analyses suggested that XBB emerged through the recombination of two cocirculating BA.2 lineages, BJ.1 and BM.1.1
Hard X-raysVarious mechanisms have been proposed to explain how seismic waves can be generated during a solar flare, several of which include a major role for accelerated electrons. To address this question further, we have selected two samples of white-light flares (WLFs): one that has ...

The large white-light flare on 1981 April 24 (≡1358 UT) was very well observed at the hard X-ray, optical, and radio wavelengths. Energetic particles escaping from the Sun were detected in the interplanetary space and in the vicinity of the Earth. The flare had distinct impulsive and grad...
