introduction: in cases of severe hard tissue loss, 2 mm circumferential ferrule is difficult to achieve. so in these cases we should use different ferrule designs. this in vitro study investigated the effect of different ferrule designs on the fracture resistance of teeth restored with bonded post and cores. materials and methods: forty freshly-extracted central incisors were endodontically tre...

Reconfigurable cores support post-release updates which shortens time-to-market while extending circuits’ lifespan. Reconfigurable cores can be provided as hard cores (ASIC) or soft cores (RTL). Soft reconfigurable cores outperform hard reconfigurable cores by preserving the ASIC synthesis flow, at the cost of lowering scalability but also exacerbating timing closure issues. This article tackle...

As an important feature of fingerprints, singular points (includingcores and deltas) not only represent the local ridge pattern characteristics, but also determine the topological structure (i.e. fingerprint type). In this paper, we have performed analysis for singular points in two aspects. (1) Based on the topology theory in 2D manifold, we deduced the relationship between cores and deltas in...

Floodplain sedimentation removes particles from fluvial transport and constructs stratigraphic records of flooding, biogeochemical sequestration and other aspects of the environmental history of river basins—insight that is enhanced by accurate geochronology. The natural fallout radionuclide 210Pb, often employed to date lacustrine and marine sediments, has previously been used to determine flo...

As an important feature of fingerprints, singular points ( core and delta) not only represent the local ridge pattern characteristics, but also determine the topological structure (i.e. fingerprint type) and largely influence the orientation field. In this paper, we have performed analysis for singular points in two aspects: (1) based on the topology theory in 2D manifold, we deduced the relati...

When calculating correlation networks from multi-electrode array (MEA) data, one works with extensive computations. Unfortunately, as the MEAs grow bigger, the time needed for the computation grows even more: calculating pair-wise correlations for current 60 channel systems can take hours on normal commodity computers whereas for future 1000 channel systems it would take almost 280 times as lon...

Carcinomas are the most commonly diagnosed cancers originating in the skin, lungs, breasts, pancreas, and other organs and glands. In most of the cases, the microenvironment within the tissue changes with the progression of disease. A key challenge is to develop a device capable of providing quantitative indicators in diagnosing cancer by measuring alteration in electrical and mechanical proper...

Floodplain sedimentation removes particles from fluvial transport and constructs stratigraphic records of flooding, biogeochemical sequestration and other aspects of the environmental history of river basins-insight that is enhanced by accurate geochronology. The natural fallout radionuclide (210)Pb, often employed to date lacustrine and marine sediments, has previously been used to determine f...

Cores were prepared from 50S ribosomal subunits by incubation with 0.4 M LiCl/Mg(++) (0.4c cores); 0.8c cores and corresponding SP(0.4-0.8) split proteins were obtained from 0.4c cores. In the fragment reaction 0.4c cores were active, but 0.8c cores were not. Activity of the 0.8c cores could be restored by reconstitution with the SP(0.4-0.8) fraction. The split proteins were separated by DEAE-c...

A brief summary is presented of our current knowledge of the structure of cold molecular cloud cores that do not contain proto-stars, sometimes known as starless cores. The most centrally condensed starless cores are known as pre-stellar cores. These cores probably represent observationally the initial conditions for protostellar collapse that must be input into all models of star formation. Th...
