A Note on Coring Extensions

A notion of a coring extension is defined and it is shown to be equivalent to the existence of an additive functor between comodule categories that factorises through forgetful functors. This correspondence between coring extensions and factorisable functors is illustrated by functors between categories of descent data. A category in which objects are corings and morphisms are coring extensions...

Rotary Sidewall Coring—Size Matters

Impacts of tree coring on indigenous trees

Advice is given on the impact to native trees of taking tree cores for research purposes. Suggested guidelines for DoC decision making on issuing permits for tree coring are provided.

Embedded coring in MPEG video compression

Coring is a well-known technique for removing noise from images. The mechanism of coring consists of transforming a noise-degraded image into a frequency-domain representation, followed by a reduction of the image transform coefficients by a (nonlinear) coring function. After inverse transforming the cored coefficients, the noise-reduced image is obtained. In this paper, we show that coring can...

Status of the ATF extraction line laser-wire

The Accelerator Test Facility (ATF) at KEK offers a very low emittance micrometre sized beam of 1.28 GeV electrons close from the conditions expected at the International Linear Collider (ILC). The ATF should soon be able to provide a bunch spacing similar to that of the ILC. This accelerator being a test facility it is possible to have dedicated machine time with custom beam optics for our tes...
