Published in 2025 at "Journal of Magnetic Resonance Imaging"

DOI: 10.1002/jmri.70006

Abstract: Vessel‐specific bolus arrival time (BAT) has become calculated with higher spatiotemporal resolution on dynamic contrast‐enhanced magnetic resonance imaging using the Golden‐angle RAdial Sparse Parallel (GRASP) technique. However, its utility in moyamoya disease (MMD) is unclear. read more here.

Published in 2019 at "Journal of Ethology"

DOI: 10.1007/s10164-019-00585-7

Abstract: Few studies on song learning have been conducted in the field. Male pied flycatchers (Ficedula hypoleuca) seem to learn song syllables in the breeding grounds. Adult males arrive first to the breeding grounds and sing… read more here.

Published in 2018 at "Journal of Seismology"

DOI: 10.1007/s10950-018-9735-z

Abstract: The first arrival time picking is a crucial step in microseismic data processing. When the signal-to-noise ratio (SNR) is low, however, it is difficult to get the first arrival time accurately with traditional methods. In… read more here.

Published in 2019 at "Arabian Journal of Geosciences"

DOI: 10.1007/s12517-019-4419-8

Abstract: Picking the seismic arrival time is an important parameter for the refraction studies. However, random noise, mainly generated by unknown sources, leads to the data quality reduction and incorrect arrival definition. Besides, picking the accurate… read more here.

Published in 2024 at "Applied Entomology and Zoology"

DOI: 10.1007/s13355-024-00864-x

Abstract: Insects with positive phototaxis fly to artificial light sources at night, stay there for a certain amount of time, and then fly away. Although many studies have been conducted on the arrival time of flying… read more here.

Published in 2021 at "Computers in biology and medicine"

DOI: 10.1016/j.compbiomed.2021.104861

Abstract: Pulse arrival time (PAT) has been broadly investigated for its potential for cuffless blood pressure (BP) estimation and ease of measurement by wearable devices. It is also of great significance to explore whether PAT conveys… read more here.
