Dynamic ventricular repolarization duration (VRD) and RR-interval coupling relates to autonomic control and myocardial electrical stability. Phase-rectification of RR-interval series separates acceleration (AC) and deceleration (DC) phases, reflecting sympathetic and parasympathetic influences on heart rate, respectively. To assess the effect of physical conditioning status on dynamic VRD and p...

reliability analysis of rock slope stability has received considerable attention in the literature. it has been used as an effective tool to evaluate uncertainty so prevalent in variables. in this research the application of the jointly distributed random variables method for probabilistic analysis and reliability assessment of rock slope stability with plane sliding is investigated. in a recen...

BACKGROUND The contribution of vegetation to shallow-slope stability is of major importance in landslide-prone regions. However, existing slope stability models use only limited plant root architectural parameters. This study aims to provide a chain of tools useful for determining the contribution of tree roots to soil reinforcement. METHODS Three-dimensional digitizing in situ was used to ob...
