Abstract: One of the problems in the development of mathematical theory of the genetic code (summary is presented in [1], the detailed - to [2]) is the problem of the calculation of the genetic code. Similar problems in the world is unknown and could be delivered only in the 21st century. One approach to solving this problem is devoted to this work. For the first time provides a detailed description of the method of calculation of the ge netic code, the idea of which was first published earlier [3]), and the choice of one of the most important sets for the calculation was based on an article [4]. Such a set of amino acid corresponds to a complete set of re.o.resentations of the plurality o f overlapping triple gene belonging to the same DNA strand. A se.o.arate issue was the initial point, triggering an iterative search process all codes submitted by the initial data. Mathematical analysis has shown that the said set contains some ambiguitie s, which have been founded because of our proposed com

Abstract: Non - Foster circuits are widely used to enhance the bandwidth of microwave circuits owing to its ability to provide the negative impe dance required to cancel transistor parasitic capacitance. In this paper, a 53 to 56 GHz MMIC (monolithic microwave integrated circuit) non - Foster enhanced class - J GaAs pHEMT (gallium arsenide pseudo high electron mobility transistor) power amplifier (PA) is proposed. The non - Foster circuit (NFC) is used to enhance the PA output power and gain. The NFC and PA were designed with WIN semiconductor’s P10 - 10 process GaAs pHEMT with periphery of 150 μm. The transistor was biased with drain supply voltage of 2V f or the NFC and 3V for the PA with respective quiescent drain - to - source current (I DSQ ) of 2mA and 3mA respectively. The PA operates from 53GHz to 56GHz with center frequency of 54.5GHz. The NFC effective negative capacitance stood at - 0.15pF at 54.5GHz. Sma ll and large signal simulations result of the PA with and without NFC were obtai
