A storage ring with tunable momentum compaction has the advantage of allowing different RMS bunch lengths to be achieved with similar RF capacity. This is potentially useful for many applications, such as a linear collider damping ring and pre-damping ring where the injected beam has a large energy spread and a large transverse emittance. A tunable bunch length also makes it easier to manipulat...

This paper presents two algorithms for generating compact test sets for combinational and full scan circuits under the transition and CMOS stuck-open fault models; Redundant Vector Elimination (RVE) and Essential Fault Reduction (EFR). These algorithms together with the dynamic compaction algorithm are incorporated into an advanced ATPG system for combin-ational circuits, called MinTest. The te...

Microscopically visible chromatin is partitioned into two major components in Arabidopsis thaliana nuclei. On one hand, chromocenters are conspicuous foci of highly condensed "heterochromatic" domains that contain mostly repeated sequences. On the other hand, less condensed and gene-rich "euchromatin" emanates from these chromocenters. This differentiation, together with the dynamic nature of c...

BACKGROUND AND PURPOSE Locally compacting the mesh of a flow diverter by a dynamic push-pull technique can accelerate intracranial aneurysm healing. We asked how this deployment strategy compares with overlapping 2 flow diverters for aneurysmal flow reduction. MATERIALS AND METHODS Using a high-fidelity virtual stent placement method, we simulated 3 flow-diverter strategies (single noncompact...

It is now widely accepted that chromatin is a highly dynamic structure that participates in all DNA-related functions, including transcription, DNA replication, repair, and programmed cell death. Chromatin compaction influences plant regeneration and development. In plants, the most popular method of detecting chromatin compaction is immunofluorescence coupled with confocal microscopy. This met...

In prokaryotes the genome is organized in a dynamic structure called the nucleoid, which is embedded in the cytoplasm. We show here that in the archaeon Haloferax volcanii, compaction and reorganization of the nucleoid is induced by stresses that damage the genome or interfere with its replication. The fraction of cells exhibiting nucleoid compaction was proportional to the dose of the DNA dama...
