On the definition of signal-to-noise ratio and contrast-to-noise ratio for FMRI data. [PDF]
Signal-to-noise ratio, the ratio between signal and noise, is a quantity that has been well established for MRI data but is still subject of ongoing debate and confusion when it comes to fMRI data.

Transparent Electrochromic Polymers with High Optical Contrast and Contrast Ratio
Colored-to-transmissive electrochromic polymers, known for their wide selection of colors and solution processability, have gained great attraction in thin film electrochromic devices that have entered the market. However, their adoption in the real world is limited due to their limited optical transparency and contrast.

Contrastive Neural Ratio Estimation
Likelihood-to-evidence ratio estimation is usually cast as either a binary (NRE-A) or a multiclass (NRE-B) classification task. In contrast to the binary classification framework, the current formulation of the multiclass version has an intrinsic and unknown bias term, making otherwise informative diagnostics unreliable.
