Single‐shot echo‐planar imaging with Nyquist ghost compensation: Interleaved dual echo with acceleration (IDEA) echo‐planar imaging (EPI) [PDF]

open access: yesMagnetic Resonance in Medicine, 2012
AbstractEcho planar imaging (EPI) is most commonly used for blood oxygen level‐dependent fMRI, owing to its sensitivity and acquisition speed. A major problem with EPI is Nyquist (N/2) ghosting, most notably at high field. EPI data are acquired under an oscillating readout gradient and hence vulnerable to gradient imperfections such as eddy current ...

The color phi phenomenon: Not so special, after all?

open access: yesPLoS Computational Biology, 2021
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.

An Efficient Channel Imbalance Estimation Method Based on Subadditivity of Linear Normed Space of Sub-Band Spectrum for Azimuth Multichannel SAR

open access: yesRemote Sensing, 2023
Azimuth multichannel (AMC) technology is one of the mainstream technical approaches to realize high-resolution wide-swath (HRWS) imaging. It has been successfully applied to several synthetic aperture radar (SAR) satellites in orbit.

Massive mimetic cosmology

open access: yesPhysics Letters B, 2019
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.

Parade of ghosts: buildings & their echoes [PDF]

open access: yesTEXT, 2019
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?
