DOI: 10.1001/jamafacial.2017.0606
Abstract: Importance Because of the soft-tissue envelope and the dimensional complexity of the muscular contraction of the mentalis muscle, the projection and shape of the chin is not determined by only the bony projection. In a… read more here.

DOI: 10.1002/advs.202202553
Abstract: Axonal projection conveys neural information. The divergent and diverse projections of individual neurons imply the complexity of information flow. It is necessary to investigate the relationship between the projection and functional information at the single… read more here.

DOI: 10.1002/mp.15520
Abstract: PURPOSE The time-of-flight (TOF) information improves signal-to-noise ratio (SNR) for positron emission tomography (PET) imaging. Existing analytical algorithms for TOF PET usually follow a filtered back-projection process on reconstructing images from the sinogram data. This… read more here.
