Geoelectrical inference of mass transfer parameters using temporal moments
[1] We present an approach to infer mass transfer parameters based on (1) an analytical model that relates the temporal moments of mobile and bulk concentration and (2) a bicontinuum modification to Archie’s law. Whereas conventional geochemical measurements preferentially sample from the mobile domain, electrical resistivity tomography (ERT) is sensitive to bulk electrical conductivity and, th...
متن کاملDirect geoelectrical evidence of mass transfer at the laboratory scale
[1] Previous field-scale experimental data and numerical modeling suggest that the dual-domain mass transfer (DDMT) of electrolytic tracers has an observable geoelectrical signature. Here we present controlled laboratory experiments confirming the electrical signature of DDMT and demonstrate the use of time-lapse electrical measurements in conjunction with concentration measurements to estimate...
متن کاملTemporal Changes in Lipid Profile and Anthropometric Parameters According to Body Mass Index, Among Iranian Adults
Introduction: The aim of this study was to examine in the lipid profile during 3.6 years and anthropometric parameters in Iranian adults the changes during 3.6 year body mass index (BMI). Materials and methods: Among participants of the Tehran lipid and glucose study (TLGS), 2940 non-diabetic adults, aged 20 years and older, who remained within the same BMI group during the two phases of the su...
متن کاملEstimation of second order parameters using probability-weighted moments
The P.O.T. method (Peaks Over Threshold) consists in using the generalized Pareto distribution (GPD) as an approximation for the distribution of excesses over a high threshold. In this work, we use a refinement of this approximation in order to estimate second order parameters of the model using the method of probability-weighted moments (PWM): in particular, this leads to the introduction of a...
متن کاملMental state inference using visual control parameters.
Although we can often infer the mental states of others by observing their actions, there are currently no computational models of this remarkable ability. Here we develop a computational model of mental state inference that builds upon a generic visuomanual feedback controller, and implements mental simulation and mental state inference functions using circuitry that subserves sensorimotor con...
