Reducing test data size is one of the major challenges in testing systems-on-a-chip. This can be achieved by test compaction and/or compression techniques. Having a partially specified or relaxed test set increases the effectiveness of compaction and compression techniques. In this paper, we propose a novel and efficient test relaxation technique for combinational circuits. It is based on criti...

Inspite of being embedded in a dense meshwork of nuclear chromatin, gene loci and large nuclear components are highly dynamic at 37°C. To understand this apparent unfettered movement in an overdense environment, we study the dynamics of a passive micron size bead in live cell nuclei at two different temperatures (25 and 37°C) with and without external force. In the absence of a force, the beads...

This paper demonstrates that multi-stage compaction (supercompaction) (high-force compaction) has an important role to play in treating metallic LLW. A specialized shear/compactor can produce significant labor and burial cost savings, as well as better operational safety and environmental protection. A case study is the supercompaction facility presently nearing completion at the DOE East Tenne...

By employing the adaptive network simulation method, we demonstrate that the ensembleaveraged stress caused by a local force for packings of frictionless rigid beads is concentrated along rays whose slope is consistent with unity: forces propagate along lines at 45 degrees to the horizontal or vertical. This slope is shown to be independent of polydispersity or the degree to which the system is...

DNA compaction induced by dodecyltrimethylammonium bromide (DTAB) is studied using atomic force microscopy (AFM) and magnetic tweezers. The morphology of DNA-DTAB complex is dependent on the DTAB concentration and incubation time. With magnesium ions, the complexes show rod- and network-like structures after approximately 5 min of incubation at low DTAB concentrations. With increasing incubatio...

Fluorescence videomicroscopy and scanning force microscopy were used to follow, in real time, chromatin assembly on individual DNA molecules immersed in cell-free systems competent for physiological chromatin assembly. Within a few seconds, molecules are already compacted into a form exhibiting strong similarities to native chromatin fibers. In these extracts, the compaction rate is more than 1...

Withdrawal of oil and gas from reservoirs causes a decrease in pore pressure and an increase in effective stress which results to a reservoir compaction. Reservoir compaction will result in surface subsidence through the elastic response of the subsurface. Usually in order to determine the subsidence above a hydrocarbon field, the reservoir compaction must be first calculated and then the effec...

I INTRODUCTION The existence of regoliths on asteroidal surfaces is supported by recent telescopic observations. On the other hand the constituent grains of gas-rich meteorites have been clearly irradiated as individual grains in both the ancient solar wind (SW) and solar cosmic rays (SCR). This irradiation could have occured within an asteroidal regolith, before the compaction of the grains in...
