A multilayer circuit assembly includes a power circuit and a numerical data circuit. Multiple graphic user interface clients can operate on widely available computers incorporating operating systems which are well suited to graphic user interface functions, while the energy control server and the inputoutput interface components can operate on a separate computer, using other or different operating systems, which are adapted to the processing performed there. The method of the invention provides a novel means of estimating cardiac output based on alveolar CO2 values rather than end-tidal CO2 values as previously practiced. There may be a loop at the top to secure the twine. The second data symbol is determined based at least in part on a second radix and at least in part on the first data symbol. There are a p-channel MIS transistor and a n-channel MIS transistor which are provided in a semiconductor substrate, and in a region of a gate electrode of the p-channel MIS transistor at least 1 nm or less apart from the interface with a gate insulating film, the oxygen concentration is 1020 cm\u22123 or more and 1022 cm\u22123 or less.
