Parade of ghosts: buildings & their echoes [PDF]
TEXT, 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?

Ghost echoes on the Earth–Moon path [PDF]
Nature, 1975 ON July 7, 1974 while using a Moon Bounce technique on 1,296 MHz I observed the appearance of strange, delayed echoes. My equipment consists of a parabolic antenna 26 feet in diameter with a circularly polarised feed horn driven with 500-W continuous wave from a transmitter.

DeepResp: Deep learning solution for respiration-induced B0 fluctuation artifacts in multi-slice GRE
NeuroImage, 2021 Respiration-induced B0 fluctuation corrupts MRI images by inducing phase errors in k-space. A few approaches such as navigator have been proposed to correct for the artifacts at the expense of sequence modification.

Study of Effect of Raw Data Compression on Azimuth Multi-channel SAR System
Leida xuebao, 2017 An effective way to achieve High Resolution and Wide Swath (HRWS) imaging capability is the multi-channel technique in azimuth. Improved resolution and swath can dramatically increase the volume of echo data in the SAR system.

Improved Row-Column-Addressed Array Imaging by Leveraging Ghost Echoes
2023 IEEE International Ultrasonics Symposium (IUS), 2023 Among various choices of 2-D ultrasound transducer arrays, the row-column-addressed (RCA) 2-D array has shown its promise for 3-D imaging. However, RCA suffers from notable edge effects and thus receives ghost echoes, which result in ghost artifacts showing in the volumetric image.

Confidence in uncertainty: Error cost and commitment in early speech hypotheses. [PDF]
PLoS ONE, 2018 Interactions with artificial agents often lack immediacy because agents respond slower than their users expect. Automatic speech recognisers introduce this delay by analysing a user's utterance only after it has been completed.

Two-Dimensional Spatial Coherence for Ultrasonic DMAS Beamforming in Multi-Angle Plane-Wave Imaging
Applied Sciences, 2019 Ultrasonic multi-angle plane-wave (PW) coherent compounding relies on delay-and-sum (DAS) beamforming of two-dimensional (2D) echo matrix in both the dimensions PW transmit angle and receiving channel to construct each image pixel.
