Maximum likelihood self-calibration for direction-dependent gain-phase errors with carry-on instrumental sensors:case of deterministic signal model by WANG Ding1, PAN Miao2, WU Ying1

“…Aim at the self-calibration of direction-dependent gain-phase errors in case of deterministic signal model,the maximum likelihood method（MLM） for calibrating the direction-dependent gain-phase errors with carry-on instrumental sensors was presented.In order to maximize the high-dimensional nonlinear cost function appearing in the MLM,an improved alternative projection iteration algorithm,which could optimize the azimuths and direction-dependent gain-phase errors was proposed.The closed-form expressions of the Cramér-Rao bound（CRB） for azimuths and gain-phase errors were derived.Simulation experiments show the effectiveness and advantage of the novel method.…”

Effects of extracellular metabolic acidosis on the homeostasis of intracellular pH in hippocampal neurons by Patrice G. Bouyer, Rossana Occhipinti, Rossana Occhipinti, Sara Taki, Fraser J. Moss, Walter F. Boron

“…We conclude with a consideration of how mathematical models—despite their inherent limitations—might assist in the interpretation of experiments and qualitative models presented in this study. Among the themes that emerge are (1) hippocampal neurons must have distinct sensors for pHo and [HCO3−]o; (2) these pHo- and [HCO3−]o-driven signal transduction pathways produce additive pHi effects in naïve neurons (those not previously challenged by an acid–base disturbance); and (3) these pathways produce highly non-additive pHi effects in neurons previously challenged by MAc.…”
