The effects of negative bias temperature instability (NBTI) on the sub-threshold performance of a pFET have been investigated by means of experimental methods. Specifically, the sub-threshold slope under static and dynamic NBTI stress has been characterized for different NBTI stress conditions. In order to perform the characterization, a proposal based on an alternative measurement technique to...

The aim of the study is to confirm the importance of discriminate different types of slope movements for a better landslide susceptibility evaluation. The study was applied to the sample area of Calhandriz (11.3 km2) in the area North of Lisbon. Sixty shallow translational slides, 23 deeper translational movements and 19 rotational movements were selected for statistical analysis. Landslide sus...

We predict that portions of the New Jersey continental slope were unstable approximately 0.5 million years ago. This instability was caused by rapid sediment loading during a Pleistocene sea-level lowstand and by flow focusing in underlying, permeable Miocene strata. The simulated instability is consistent with soft-sediment deformation and small slumps in Pleistocene strata of the Hudson Apron...

We present a unified approach for qualitative and quantitative analysis of stability and instability dynamics of positive bright solitons in multidimensional focusing nonlinear media with a potential (lattice), which can be periodic, periodic with defects, quasiperiodic, single waveguide, etc. We show that when the soliton is unstable, the type of instability dynamic that develops depends on wh...
