Published in 2019 at "Magnetic Resonance in Chemistry"

DOI: 10.1002/mrc.4776

Abstract: The development of new tools to improve the quality of nuclear magnetic resonance (NMR) spectra is a challenging task. The concept of “perfect NMR” includes the design of robust pulse sequences that allow an investigator… read more here.

Published in 2020 at "Journal of General Internal Medicine"

DOI: 10.1007/s11606-020-06175-5

Abstract: Background Despite evidence of effectiveness, most US hospitals do not deliver hospital-based addictions care. ECHO (Extension for Community Healthcare Outcomes) is a telementoring model for providers across diverse geographic areas. We developed and implemented a… read more here.

Published in 2019 at "Magnetic resonance imaging"

DOI: 10.1016/j.mri.2018.11.018

Abstract: A 2D gradient-echo EPI is commonly employed for arterial spin labeling (ASL) readout to achieve fast whole brain coverage measurements. However, such a readout suffers from susceptibility artifacts induced by magnetic field inhomogeneities. To reduce… read more here.

Published in 2025 at "Earth and Space Science"

DOI: 10.1029/2025ea004262

Abstract: X‐band Phased array radars are characterized by high spatial and temporal resolution, but suffer from a range of data quality problems, such as echo voids after the filtering of ground clutter, abnormal radials, radial obstructions… read more here.

Published in 2017 at "Scientific Reports"

DOI: 10.1038/s41598-017-08051-5

Abstract: A quantum memory protocol of controlled ac Stark echoes (CASE) based on a double rephasing photon echo scheme via controlled Rabi flopping is proposed. The double rephasing scheme of photon echoes inherently satisfies the no-population… read more here.

Published in 2023 at "Endoscopy"

DOI: 10.1055/a-2037-5802

Abstract: Endoscopic ultrasonography (EUS), with its high spatial resolution, is indispensable for diagnosing the nature and invasiveness of gallbladder lesions [1–3]. The gallbladder and bile ducts are hollow organs that do not originally have internal echo… read more here.

Published in 2024 at "ICES Journal of Marine Science"

DOI: 10.1093/icesjms/fsae085

Abstract: In trawl-acoustic methods, machine learning can objectively assign species composition to echo-traces, providing a reproducible approach for improving biomass assessments and the study of schooling behaviour. However, the automatic classification of schools in multispecies environments… read more here.
