Transparent Electrochromic Polymers with High Optical Contrast and Contrast Ratio [PDF]
JACS AuColored-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.

Oblique views of chest radiography from a designed rotation angle recommendation increase the contrast ratio between obscured lesions and surrounding structures [PDF]
Thoracic Cancer, 2019 Background Chest radiography (CXR) is the main tool used to detect pulmonary nodules. Lateral views of CXR are less effective and the aim of our study was to develop a rotation angle recommendation model to obtain the best oblique CXR with significantly ...

Colorless-to-colorful switching electrochromic polyimides with very high contrast ratio [PDF]
Nature Communications, 2019 Electrochromic polymers (ECPs) receive great attention due to their facile colour tunablility, however colourless-to-black ECPs with high contrast ratio are still unattainable.

On the definition of signal-to-noise ratio and contrast-to-noise ratio for FMRI data. [PDF]
PLoS ONE, 2013 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.

Contrastive Neural Ratio Estimation
Advances in Neural Information Processing Systems 35, 2022 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.
