Wedescribe a newmethod of distinguishing between ordered and chaotic orbits, which is much faster than the methods used up to now, namely (1) the distribution of the Poincaré consequents, (2) the Lyapunov characteristic number and (3) the distribution of the rotation angles. This method is based on the distribution of the helicity angles (the angles of small deviations ξ from a given orbit with...

Using the family symmetry, in the neutrino mass matrix we remove the Yukawa coupling (arising in the Dirac type mass between the heavy neutrinos and light lepton doublets) dependence in the double seesaw mechanism so that it is directly proportional to the mass matrix m of heavy Majorana neutrinos. Then, the neutrino mass matrix is given by the family symmetry at high energy scale. With the per...

This paper deals with nonuniform transmission lines which are excited at high frequencies. Networks of those lines are formed and they are described by the BLT–equation. The essential ingredients in this equation are the scattering and the propagation supermatrices. For our investigations we derive these quantities from the product integral solution of generalized telegrapher’s equations. The m...

INTRODUCTION Anatomical markers can help to guide lag screw placement during surgery for internal fixation of fifth metatarsal base fractures. This study aimed to identify the optimal anatomical markers and thus reduce radiation exposure. METHODS A total of 50 patients in Huashan Hospital, Shanghai, China, who underwent oblique foot radiography in the lateral position were randomly selected. ...

The chiral Hamiltonian for twisted graphene bilayers is written as a $2\ifmmode\times\else\texttimes\fi{}2$ matrix operator by renormalization of the that takes into account particle-hole symmetry. This results in an effective terms Pauli matrices with three contributions: kinetic term, confinement potential, and non-Abelian gauge field. action proposed maps zero-mode flat bands ground states. ...

in a sociological review of novels, the connection between structure and content of the story studied by considering the conditions and changes in society and environment in which they are created, and the modality of artistic reflection of the society in the world of the literary work is reviewed and analyzed. in this article, the authors present an analysis of the works of the famous algerian...
