Published in 2017 at "Geophysical Research Letters"

DOI: 10.1002/2017gl073832

Abstract: The Semiannual Oscillation (SAO) is a twice-yearly northward movement (in May-June-July, MJJ, and November-December-January, NDJ) of the circumpolar trough of sea level pressure (SLP) in the Southern Hemisphere with effects throughout the troposphere. During MJJ… read more here.

Published in 2018 at "Journal of Geophysical Research"

DOI: 10.1002/2017je005419

Abstract: Thermal infrared spectra acquired by Cassini/Composite InfraRed Spectrometer (CIRS) in limb-viewing geometry in 2015 are used to derive 2-D latitude-pressure temperature and thermal wind maps. These maps are used to study the vertical structure and… read more here.

Published in 2019 at "Cell Biology International"

DOI: 10.1002/cbin.11242

Abstract: Most living organisms have physiological and behavioral circadian rhythms controlled by molecular clocks. In mammals, several core clock genes show self‐perpetuating oscillation profiles of their messenger RNAs (mRNAs) and proteins through an auto‐regulatory transcription–translation feedback… read more here.

Published in 2017 at "International Transactions on Electrical Energy Systems"

DOI: 10.1002/etep.2233

Abstract: Summary Low-frequency oscillation occurs easily in a hydropower system with weak connected grid. Some oscillation behaviors cannot be explained by linear analysis method. According to unexplained oscillation frequency of hydropower stations, second-order oscillation mode of… read more here.

Published in 2019 at "Hippocampus"

DOI: 10.1002/hipo.23093

Abstract: Throughout the brain, reciprocally connected excitatory and inhibitory neurons interact to produce gamma‐frequency oscillations. The emergent gamma rhythm synchronizes local neural activity and helps to select which cells should fire in each cycle. We previously… read more here.

Published in 2017 at "International Journal of Climatology"

DOI: 10.1002/joc.4818

Abstract: The impacts of the Madden-Julian oscillation (MJO) on precipitation over Northeast Brazil (NEB, also known as Nordeste) are evaluated based on daily raingauge data from 492 stations over 30-year period (1981–2010). Composites of precipitation, outgoing… read more here.
