Frontiers in Public Health, 2022 BackgroundThe COVID-19 pandemic, which began at the end of 2019, has led to a significant increase in the demand for face masks in Germany and around the globe. Since non-reusable masks are often not correctly disposed of and are not biodegradable, their

Optimal Masks for Low-Degree Solar Acoustic Modes [PDF]
, 2000 We suggest a solution to an important problem of observational helioseismology of the separation of lines of solar acoustic (p) modes of low angular degree in oscillation power spectra by constructing optimal masks for Doppler images of the Sun. Accurate

Silver Standard Masks for Data Augmentation Applied to Deep-Learning-Based Skull-Stripping
, 2017 The bottleneck of convolutional neural networks (CNN) for medical imaging is the number of annotated data required for training. Manual segmentation is considered to be the "gold-standard".

Coset Sum: an alternative to the tensor product in wavelet construction
, 2013 A multivariate biorthogonal wavelet system can be obtained from a pair of multivariate biorthogonal refinement masks in Multiresolution Analysis setup. Some multivariate refinement masks may be decomposed into lower dimensional refinement masks.

Masks, Mirrors, and Mediated Perception: Reflective Viewing in the House of the Gilded Cupids
Arts, 2019 Masks, as a locus of mimetic potential, serve both to typify and to disguise, distilling character traits and translating them visually, even as they hide the visage of those who might wear them, suggesting a performative persona through the partial ...

An Algebraic Perspective on Multivariate Tight Wavelet Frames. II
, 2013 Continuing our recent work we study polynomial masks of multivariate tight wavelet frames from two additional and complementary points of view: convexity and system theory.
