Measuring brain beats: Cardiac‐aligned fast functional magnetic resonance imaging signals
Human Brain Mapping, Volume 44, Issue 1, Page 280-294, January 2023., 2023 Blood and cerebrospinal fluid (CSF) pulse and flow throughout the brain, driven by the cardiac cycle. We use rapid functional magnetic resonance imaging (fMRI) measurements to assess blood and CSF flow dynamics in a conventional 3 T magnetic resonance imaging scanner.

The Doppler effect and similar triangles
Results in Physics, 2019 The Euclidean version of Doppler effect will be explained using the properties of similar triangles. These properties will serve to explain the relationship between frequencies of propagated wavefronts, number of wavefronts and the time of emitting and ...

Generalized models for quantifying laterality using functional transcranial Doppler ultrasound
Human Brain Mapping, Volume 44, Issue 1, Page 35-48, January 2023., 2023 Transcranial functional Doppler Ultrasound has been used to assess brain lateralization, but the methods used to extract a laterality index (LI) have involved simple averaging over a period of interest. Here, we compare results from that method with results from a generalized linear models (GLM) approach similar to that used in functional magnetic ...

ChemPhysChem, EarlyView.Relative energies of the cis and trans conformers of the protonated tetrapeptide, Gly‐Pro‐Gly‐Gly, selected by ion mobility spectrometry are measured using threshold collision‐induced dissociation. The trans conformation was found to be more stable than the cis conformation by 4.5 ± 2.5 kJ mol−1 at 0 K, a value in agreement with several levels of ...
