A New Combination Scheme of GRAPPA and Compressed Sensing for Accelerated Magnetic Resonance Imaging
Chinese Journal of Magnetic Resonance, 2018 Both compressed sensing (CS) and parallel imaging (PI) can be used to accelerate magnetic resonance imaging (MRI) by under-sampling the k space data. Several methods combining CS and PI have been proposed to further improve the scanning speed.

Compensation temperatures and exchange bias in La1.5Ca0.5CoIrO6 [PDF]
, 2016 We report on the study of magnetic properties of the La1.5Ca0.5CoIrO6 double perovskite. Via ac magnetic susceptibility we have observed evidence of weak ferromagnetism and reentrant spin glass behavior on an antiferromagnetic matrix.

O2 adsorbed on Ptn clusters: Structure and optical absorption
AIP Advances, 2018 The interaction of O2 with Ptn and the optical absorption properties of PtnO2 were explored under the framework of density functional theory. The Ptn (n= 2, 4, 6, 9, 10, 14, 18, 22, and 27) clusters were selected, which were reported as magnetic number ...

Role of the intercalated ions on the high capacitance behavior of Ti3C2Tx MXene nanohybrids
Nanocomposites, 2023 [Formula: see text] (MXene) is prone to surface oxidation because of the presence of oxygen surface terminals in its surfaces. In this work, the effect of oxygen surface terminals has been reduced by replacing it with other surface terminals or thin ...

New magnetic phase of the chiral skyrmion material Cu2OSeO3 [PDF]
Science Advances, 2018 A new magnetic phase is reported in the chiral magnet, Cu2OSeO3, which is predicted to affect its physical properties. The lack of inversion symmetry in the crystal lattice of magnetic materials gives rise to complex noncollinear spin orders through ...
