Lipid elimination with an echo‐shifting N/2‐ghost acquisition (LEENA) MRI [PDF]
Purpose The Dixon techniques provide uniform water‐fat separation but require multiple image sets, which extend the overall acquisition time. Here, an alternative rapid single acquisition method, lipid elimination with an echo‐shifting N/2‐ghost ...

Multiple-scattering-induced "ghost echoes" in GPM DPR observations of a tornadic supercell [PDF]
Evidence of multiple-scattering-induced pulse stretching for the signal of both frequencies of the Dual-Frequency Precipitation Radar (DPR) on the Global Precipitation Measurement (GPM) mission Core Observatory satellite is presented on the basis of ...

In detecting hypersonic vehicles, the radar echo signal is coupled with an intra-pulse Doppler frequency (I-D frequency) component caused by relative motion of a plasma sheath (PSh) and the vehicle, which can induce the phenomenon of a ghost target in a ...

This article discusses four recently released refugee films: Dolce Fine Giornata, Atlantics, Island of the Hungry Ghosts, and Life Overtakes Me. It draws on a range of theoretical frames, including the work of Avery Gordon and Jacques Derrida on spectrality, in order to outline the original concept of ‘fugitive aesthetics’, the narrative and stylistic ...

Quantification and reduction of ghosting artifacts in interleaved echo‐planar imaging [PDF]
AbstractA mathematical analysis of ghosting artifacts often seen in interleaved echo‐planar images (EPI) is presented. These artifacts result from phase and amplitude discontinuities between lines of k‐space in the phase‐encoding direction, and timing misregistrations from system filter delays.

Boosting BOLD fMRI by K-Space density weighted echo planar imaging [PDF]
Functional magnetic resonance imaging (fMRI) has become a powerful and influential method to non-invasively study neuronal brain activity. For this purpose, the blood oxygenation level-dependent (BOLD) effect is most widely used. T2* weighted echo planar

Fragmentation de l’être. Mémoire et identité dans les mangas
Le développement de la relation entre la machine et l’individu trouve un écho fertile au sein des mangas. L’étude d’oeuvres emblématiques, comme Ghost in the Shell, Gunnm, Lain et les adaptations de Hiroshi Mori, permet de mettre en lumière leurs ...

We study the first cosmological implications of the mimetic theory of massive gravity recently proposed by Chamseddine and Mukhanov. This is a novel theory of ghost-free massive gravity which additionally contains a mimetic dark matter component.

Mutual Interferences of a True-Random LiDAR With Other LiDAR Signals
We investigate characteristics and impacts of the mutual interference to a LiDAR using an analog true-random signal, for autonomous vehicle applications.
