A well defined glass state obtained by oscillatory shear

Well-Defined Coverage Metrics for the Glass Box Test

The Glass Box Test (GBT), also known as White Box Test or Structural Test, shows which parts of the program under test have, or have not, been executed. Many GBT tools are available for almost any programming language. Industry standards for safety-critical software require a very high or even complete coverage. At first glance, the GBT seems to be a well-established and mature testing techniqu...

Reduction by well-defined objectives.

Examination of programmes of experimental work involving live animals indicates scope for worthwhile reduction in animal usage by identifying more clearly the objectives of the different stages of a programme. Having a defined first objective for new or transferred methodology as "to optimise the methods", rather than an exploratory "try it with a few animals and modify" approach, is more likel...

Well-defined steady-state response does not imply CICS

Systems for which each constant input gives rise to a unique globally attracting equilibrium are considered. A counterexample is provided to show that inputs which are only asymptotically constant may not result in states converging to equilibria (failure of the converging-input converging state, or “CICS” property).

Shear localization in a model glass.

Using molecular dynamics simulations, we show that a simple model of a glassy material exhibits the shear localization phenomenon observed in many complex fluids. At low shear rates, the system separates into a fluidized shear band and an unsheared part. The two bands are characterized by a very different dynamics probed by a local intermediate scattering function. Furthermore, a stick-slip mot...
