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.

Hong Kong echoes across English ghost lands: A decolonizing of English-language poetry
Journal of Postcolonial Writing, 2023 his article focuses on three women poets who deploy a Hong Kong Chinese imaginary, an imaginarium filled with memories, popular cultural references, fragments of Cantonese, and isolated Chinese characters. Jennifer Lee Tsai was born in the UK of Hong Kong immigrant parents, while Jennifer Wong migrated from Hong Kong to the UK first to study and then ...

The effect of residual Nyquist ghost in quantitative echo-planar diffusion imaging [PDF]
Magnetic Resonance in Medicine, 1999 Single-shot diffusion-weighted echo-planar imaging (EPI) is typically used for most clinical diffusion studies due to its low sensitivity to patient motion. Although the Nyquist ghost artifact in EPI can be substantially reduced, there is frequently a residual ghost with low signal intensity.

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.

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.
