We give an action for the massless spinning particle in pseudoclassical mechanics by using grassmann variables. The constructed action is invariant under τ -reparametrizations, local SUSY and O(N) transformations. After quantization, for the special case N = 2, we get an action which describes the spin 0, 1 and topological sectors of the massless DKP theory.

In a previous work, we explored zone broadening and the achievable plate numbers in linear drift tube ion mobility-mass spectrometry through developing plate-height model [1]. On basis of these findings, present theoretical study extends by exploring peak-to-peak resolution peak capacity mobility separations. The first part provides critical overview chromatography-influenced equations, includi...

Symmetries of a partial Latin square are primarily determined by its autotopism group. Analogously to the case of Latin squares, given an isotopism Θ, the cardinality of the set PLSΘ of partial Latin squares which are invariant under Θ only depends on the conjugacy class of the latter, or, equivalently, on its cycle structure. In the current paper, the cycle structures of the set of autotopisms...

In the article, the influencing factors of the high-voltage transmission line running were analyzed, the important meanings of the real-time online monitoring of the line contact point aging for guaranteeing the safe and stable running of the lines were pointed out, the theoretical reference and the project selection of the high-voltage transmission line temperature monitoring were discussed, a...

A linear superposition method was used for modeling the time history of the production blast vibrations and optimizing the blast sequence to reduce vibration levels in Sar-Cheshmeh copper mine, Kerman, Iran. A single-hole blast for modeling and two double-hole blasts with time delays of 25 and 65 ms between two holes for modeling validation were carried out. The generated vibrations were measur...
