An organic electrolytic solution including a lithium salt, an organic solvent, and a linear or cyclic polymerizable monomer that is negatively charged due to localization of electrons on the monomer, and a lithium battery employing the same. Specifically, a process for producing a thermoplastic resin composition comprises melt-kneading a mixture of a polyolefin wax which has a passing ratio through a mesh having a sieve opening of 5. Detector design is improved by the use of optically adiabatic scintillators. After obtaining an initial estimate of the position of the target mobile node, the target mobile node can serve as virtual anchors to estimate the positions of other mobile nodes, which can then be used to further refine the position estimate of the target mobile node.
