recommendations! Published in 2024 at "Magnetic Resonance in Medicine"

DOI: 10.1002/mrm.30358

Abstract: Flow quantification using phase‐contrast (PC) MRI is based on steady‐state gradient echo (GRE) sequences and is hampered by spatially varying background phase offsets. The purpose of this work was to investigate the effect of steady‐state… read more here.

DOI: 10.1007/s10043-018-0464-x

Abstract: An asymmetric image encryption scheme is proposed using a phase-truncated discrete multiple-parameter fractional Fourier transform (DMPFRFT). After applying a pixel-scrambling operation and random-phase mask, an asymmetric ciphertext with stationary white noise can be obtained using… read more here.

DOI: 10.1103/physrevapplied.19.l051002

Abstract: We propose an analytical framework to design actively tunable narrowband thermal emitters at infrared frequencies. We exemplify the proposed design rules using phase-change materials (PCM), considering dielectric-to-dielectric PCMs (e.g. GSST) and dielectric-to-metal PCMs (e.g. $\mathrm{VO_2}$).… read more here.
