Criterion for purely elastic Taylor-Couette instability in the flows of shear-banding fluids [PDF]
, 2011 In the past twenty years, shear-banding flows have been probed by various techniques, such as rheometry, velocimetry and flow birefringence. In micellar solutions, many of the data collected exhibit unexplained spatio-temporal fluctuations.

Gradient and vorticity banding [PDF]
, 2008 "Banded structures" of macroscopic dimensions can be induced by simple shear flow in many different types of soft matter systems. Depending on whether these bands extend along the gradient or vorticity direction, the banding transition is referred to as "

Using large-scale citizen science ringing data as a means of calculating maximum longevity in birds
Bothalia: African Biodiversity & Conservation, 2019 This article calculates estimates of avian longevity for southern African Passeriformes and demonstrates the impact citizen scientists have on data volumes curated by the South African Bird Ringing Unit (SAFRING).

Potential "ways of thinking" about the shear-banding phenomenon [PDF]
, 2011 Shear-banding is a curious but ubiquitous phenomenon occurring in soft matter. The phenomenological similarities between the shear-banding transition and phase transitions has pushed some researchers to adopt a 'thermodynamical' approach, in opposition ...

Convex Banding of the Covariance Matrix [PDF]
, 2014 We introduce a new sparse estimator of the covariance matrix for high-dimensional models in which the variables have a known ordering. Our estimator, which is the solution to a convex optimization problem, is equivalently expressed as an estimator which ...

Correction of Banding Errors in Satellite Images With Generative Adversarial Networks (GAN)
IEEE Access, 2023 This research proposes an innovative method for correcting banding errors in satellite images based on Generative Adversarial Networks (GAN). Small satellites are frequently launched into space to obtain images that can be used in scientific or military ...

A non-monotonic constitutive model is not necessary to obtain shear banding phenomena in entangled polymer solutions [PDF]
, 2008 In 1975 Doi and Edwards predicted that entangled polymer melts and solutions can have a constitutive instability, signified by a decreasing stress for shear rates greater than the inverse of the reptation time.

Velocity profiles in shear-banding wormlike micelles [PDF]
, 2002 Using Dynamic Light Scattering in heterodyne mode, we measure velocity profiles in a much studied system of wormlike micelles (CPCl/NaSal) known to exhibit both shear-banding and stress plateau behavior.
