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.

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 ...

The color phi phenomenon: Not so special, after all?
We show how anomalous time reversal of stimuli and their associated responses can exist in very small connectionist models. These networks are built from dynamical toy model neurons which adhere to a minimal set of biologically plausible properties.

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 ...

Parade of ghosts: buildings & their echoes [PDF]
At the centre of this personal essay is my effort to understand the impact of buildings on literature, and the impact of literature on buildings. What happens when the built environment is drastically altered? How does memory mediate between what used to be there and what replaced it?

Lipid elimination with an echo‐shifting N/2‐ghost acquisition (LEENA) MRI [PDF]
PurposeThe 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 acquisition (LEENA), was introduced.MethodsThe LEENA method utilized a fast imaging with steady‐state free ...

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.
