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 2024 at "Advanced Functional Materials"

DOI: 10.1002/adfm.202415988

Abstract: The electron pairing mechanisms in topological superconductors are pivotal for understanding the emergent topology‐related quantum states and play key roles in condensed matter physics. Theoretically, the quantization of magnetic flux in nano‐hole arrays within topological… read more here.

Published in 2025 at "Advanced Optical Materials"

DOI: 10.1002/adom.202500213

Abstract: Growing interest has emerged in the alternating current (AC) photovoltaic effect, distinct from the traditional direct‐current (DC)‐based photovoltaic effect. This effect arises from the relative movement and reorganization of quasi‐Fermi levels at material interfaces when… read more here.

Published in 2025 at "Advanced Science"

DOI: 10.1002/advs.202570154

Abstract: Tunable Polariton Rabi Oscillation This cover illustration highlights the tunable Rabi oscillation of exciton‐polaritons in phase‐changing perovskites. As the perovskite undergoes a structural phase transition, lattice distortion due to polar cation alignments can occur, inducing… read more here.

Published in 2024 at "Asia-Pacific Journal of Chemical Engineering"

DOI: 10.1002/apj.3145

Abstract: Self‐excited thermoacoustic instability (SETAI) is a dangerous phenomenon in combustion equipment. While it is widely acknowledged that SETAI behavior is determined by the couple between pressure and heat release oscillation, their phase difference is difficult… 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 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.
