As technology nodes shrink to 90 nanometers and below, chips become much more difficult to manufacture. In-die process variations increase substantially at 90 nm — even more at 65 nm. If these effects ...

Timing and variability have long been missing from automated transistor-level simulation tools. At advanced nodes, an update will be required. Simulation, a workhorse tool for semiconductor design, is ...

Variation is becoming a major headache at advanced nodes, and issues that used to be dealt with in the fab now must be dealt with on the design side, as well. What is fundamentally changing is that ...

Copy number variation (CNV) refers to an increase or decrease in the number of copies of a DNA sequence in a genome, which can subsequently be implicit in promoting aberrant gene expression patterns ...

Fossil samples almost always accumulate on timescales much longer than the life spans of individual organisms. This time-averaging has the potential to inflate the variability of fossil samples ...

Take Sigmetrix, for instance—a software solutions provider that helps users achieve robust designs through tolerance analysis and the correct application of GD&T. During 3D Experience World in Houston ...

Background: Chronic obstructive pulmonary disease (COPD) is an important cause of mortality with marked geographic variations in Great Britain. Additional factors beyond cigarette smoking are likely ...
