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.

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.

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.
