A shape can be more difficult to identify when other shapes are near it. For example, when
several grating patches are viewed parafoveally, observers are unable to report the …

The discrete wavelet transform (DWT) decomposes an image into bands that vary in spatial
frequency and orientation. It is widely used for image compression, measures of the visibility …

We have implemented a model of contrast gain control in human vision that incorporates a
number of key features, including a contrast sensitivity function, multiple oriented bandpass …

The acute course of COVID-19 is variable and ranges from asymptomatic infection to fulminant
respiratory failure. Patients recovering from COVID-19 can have persistent symptoms and …

For a patch of random visual texture embedded in a surrounding background of similar texture,
we demonstrate that the perceived contrast of the texture patch depends substantially on …

Objective. Small series suggest mycophenolate mofetil (MMF) is well tolerated and may be
an effective therapy for connective tissue disease-associated interstitial lung disease (CTD-…

Background Given the phenotypic similarities between rheumatoid arthritis (RA)–associated
interstitial lung disease (ILD) (hereafter, RA-ILD) and idiopathic pulmonary fibrosis, we …

WE hear periodic sounds, or tones, by means of parallel auditory filters, each tuned to a band
of temporal frequency 1 , and we see periodic patterns, or gratings, by means of parallel …

Background The cornerstone of hypersensitivity pneumonitis (HP) management is having
patients avoid the inciting antigen (IA). Often, despite an exhaustive search, an IA cannot be …

Interstitial lung disease (ILD) is a common pulmonary manifestation of rheumatoid arthritis.
There is lack of clarity around predictors of mortality and disease behaviour over time in these …
