TL;DR: In this paper , the authors conducted a serological survey of 304 serum samples from E. helvum fruit bats that were captured for human consumption in Makurdi, Nigeria using pseudotyped viruses, and screened the samples for neutralising antibodies against viruses from the Coronavirus, Filoviridae, Orthomyxovirusidae and Paramyxovirides families.

TL;DR: In this article, the variability of 474,179 objects in 8.1 deg^2 of the NDWFS Bootes field was investigated, focusing on the 3.6 and 4.5 micron bands.

TL;DR: In this article, a high-average power S-band multiple-beam klystron was designed for high-repetition rate electron gun with high average power and 13% 1-dB bandwidth.

Abstract: We identify new Y- and T-type brown dwarfs from the WISE All Sky data release using images obtained in filters that divide the traditional near-infrared H and J bands into two halves -- specifically CH4s & CH4l in the H and J2 & J3 in the J. This proves to be very effective at identifying cool brown dwarfs via the detection of their methane absorption, as well as providing preliminary classification using methane colours and WISE-to-near-infrared colours. New and updated calibrations between T/Y spectral types and CH4s-CH4l, J3-W2, and CH4s-W2 colours are derived, producing classification estimates good to a few spectral sub-types. We present photometry for a large sample of T and Y dwarfs in these filters, together with spectroscopy for 23 new ultra-cool dwarfs - two Y dwarfs and twenty one T dwarfs. We identify a further 8 new cool brown dwarfs, which we have high confidence are T dwarfs based on their methane photometry. We find that, for objects observed on a 4m-class telescope at J band magnitudes of ~20 or brighter, CH4s-CH4l is the more powerful colour for detecting objects and then estimating spectral types. Due to the lower sky background in the J-band, the J3 and J2 bands are more useful for identifying fainter cool dwarfs at J>22. The J3-J2 colour is poor at estimating spectral types. But fortunately, once J3-J2 confirms that an object is a cool dwarf, the J3-W2 colour is very effective at estimating approximate spectral types.

TL;DR: The MICHELLE code as mentioned in this paper is a finite element particle in cell (FEMPC) code for 2D and 3D particle beam formation, transport, and collection on desktop computers.
