The final output of this stage is obtained by in- tegrating y LIN (t, f ) over a short window, μ midbrain (t, τ), with time constant τ = 8 milliseconds mimicking the further ... content [5]. This finding has inspired a multi- scale model representation of speech modulations that has proven useful in assessment of speech intelligibility [6], dis- criminating speech fro...

... associated with Survivin levels indicates the increase in risk of death for 100 fold increase in Survivin expression (Table 3). Since only these four independent variables were retained by the Cox ... treatments. Our findings are of particular relevance also from the tumor biology viewpoint because the Survivin gene encodes a key anti-apoptotic protein belonging to the inhibitor of apopto...
