This paper introduces an alternative formalism for deriving the Dirac operator and equation. The use of this formalism concomitantly generates a separate operator coupled to the Dirac operator. When operating on a Clifford field, this coupled operator pro... see more

A massive gauge invariant formulation for scalar (o)and antisymmetric (Cmnp) fields with a topological coupling, which provides a mass for the axion field, is considered. The dual and local equivalence with the nongauge invariant proposal is established, ... see more

We have discussed the gauge invariance of nonlinear Klein-Gordon equation which describes the interaction of electromagnetic initially proposed by Hermann Weyl. The construction of nonlinear Klein-Gordon itself is formulated by two classical conservation ... see more

Satellite altimetry missions and tide gauges allow the monitoring of sea level variations over time. While tide gauges monitor sea level relative to a local reference, satellite altimetry missions do so in relation to the Earth’s geocenter. From the compa... see more

The object of research is the operation of the drill string in the local bend of the well. One of the most problematic aspects in this case is the establishment of its stress-strain state. This is very important information, which, in particular, is used ... see more

Educational measurement, including measurement of learning outcomes include a variety of fields, depending on the object of learning what to measure. Therefore, the problem in this paper are: 1) whether the item response theory or theories of modern tests... see more

First paragraph:This special issue examines the effectiveness of organizing and conducting formal impact assess­ments in measuring the economic impacts and opportunity costs associated with local food system policies, programming, and investment. It featu... see more

Problems of the Standard Model, associated with the introduction of an electromagnetic field as a linear combination of fields on which various gauge groups representations are implemented, are analyzed. In this paper, we pay attention to the fact th... see more
