The Fate and Transport of Chlorinated Polyfluorinated Ether Sulfonates and Other PFAS through Industrial Wastewater Treatment Facilities in China
Liu, Shiyang; Jin, Biao; Arp, Hans Peter; Chen, Wenwen; Liu, Yi; Zhang, Gan (Peer reviewed; Journal article, 2022)Wastewater from certain industrial processes can be primary emission sources of per- and polyfluoroalkyl substances (PFAS) and fluorinated alternatives like chlorinated polyfluorinated ether sulfonates (Cl-PFESA). Two such ... -
Inter-source seismic interferometry by multidimensional deconvolution (MDD) for borehole sources
Liu, Yi; Arntsen, Børge; Wapenaar, Kees; Romdhane, Anouar (Book, 2014)Seismic interferometry (SI) is usually implemented by crosscorrelation (CC) to retrieve the impulse response between pairs of receiver positions. An alternative approach by multidimensional deconvolution (MDD) has been ... -
Moving element analysis of high-speed train-slab track system considering discrete rail pads
Lei, Tuo; Dai, Jian; Ang, Kok Keng; Li, Kun; Liu, Yi (Peer reviewed; Journal article, 2021)This paper presents a study of the dynamic behavior of a coupled train-slab track system considering discrete rail pads. The slab track is modeled as a three-layer Timoshenko beam. The study is carried out using the moving ... -
Proteome-wide Mendelian randomization in global biobank meta-analysis reveals multi-ancestry drug targets for common diseases
Zhao, Huiling; Rasheed, Humaria; Nøst, Therese Haugdahl; Cho, Yoonsu; Liu, Yi; Bhatta, Laxmi; Bhattacharya, Arjun; Hemani, Gibran; Davey Smith, George; Brumpton, Ben Michael; Zhou, Wei; Neale, Benjamin M.; Gaunt, Tom R.; Zheng, Jie (Peer reviewed; Journal article, 2022)Proteome-wide Mendelian randomization (MR) shows value in prioritizing drug targets in Europeans but with limited evidence in other ancestries. Here, we present a multi-ancestry proteome-wide MR analysis based on ... -
Retrieving virtual reflection responses at drill-bit positions using seismic interferometry with drill-bit noise
Liu, Yi; Draganov, Deyan; Wapenaar, Kees; Arntsen, Børge (Journal article; Peer reviewed, 2016)In the field of seismic interferometry, researchers have retrieved surface waves and body waves by cross-correlating recordings of uncorrelated noise sources to extract useful subsurface information. The retrieved wavefields ... -
SYNTHETIC DATA FOR DNN-BASED DOA ESTIMATION OF INDOOR SPEECH
Gelderblom, Femke B.; Kvam, Johannes; Liu, Yi; Myrvoll, Tor Andre (Chapter, 2021)This paper investigates the use of different room impulse response (RIR) simulation methods for synthesizing training data for deep neural network-based direction of arrival (DOA) estimation of speech in reverberant rooms. ... -
Up- and downgoing borehole wavefield retrieval using single component borehole and reflection data
Liu, Yi; Arntsen, Børge; van der Neut, Joost; Wapenaar, Kees (Journal article; Peer reviewed, 2018)A standard procedure in processing vertical seismic profile (VSP) data is the separation of up- and downgoing wavefields. We show that these wavefields in boreholes can be retrieved using only single-component data, given ...
