Discrete Symmetries on the Light Front and a General Relation Connecting Nucleon Electric Dipole and Anomalous Magnetic Moments
We consider the electric dipole form factor, F_3(q^2), as well as the Dirac
and Pauli form factors, F_1(q^2) and F_2(q^2), of the nucleon in the
light-front formalism. We derive an exact formula for F_3(q^2) to complement
those known for F_1(q^2) and F_2(q^2). We derive the light-front representation
of the discrete symmetry transformations and show that time-reversal- and
parity-odd effects are captured by phases in the light-front wave functions. We
thus determine that the contributions to F_2(q^2) and F_3(q^2), Fock state by
Fock state, are related, independent of the fundamental mechanism through which
CP violation is generated. Our relation is not specific to the nucleon, but,
rather, is true of spin-1/2 systems in general, be they lepton or baryon. The
empirical values of the anomalous magnetic moments, in concert with empirical
bounds on the associated electric dipole moments, can better constrain theories
of CP violation. In particular, we find that the neutron and proton electric
dipole moments echo the isospin structure of the anomalous magnetic moments,

Formation Of creative abilities of schoolchildren in performing projects based on the Arduino platfor
Research problem: how to increase the effectiveness of the formation of creative abilities of schoolchil-dren in the classroom of robotics in the context of further education. The purpose of the described study is to determine and justify the optimal ways of creating creative abilities for students in robotics classes, on which complex projects based on the Arduino platform are implemented. Methodology and research methods include theories of creative abilities by J. Guildford, C. Taylor, G. Gruber and Ya. A. Ponomarev, methods of analysis, synthesis, abstraction and generalization, pedagogical observa-tion, as well as analysis of activity products. The main results of the study show the productivity of pro-ject activities using modern robotic kits to form the creative abilities of students. In addition, they in-clude substantiating the significance of the case method, reference circuits based on a given structure and test cards in the formation of creative abilities of students in robotics classes when performing technical research projects based on the Arduino platform. The scientific novelty of the research results consists in the fact that for the first time the existing pedagogical experience and perspective opportuni-ties for the formation of creative abilities of students in robotics classes while performing technical re-search projects based on the Arduino platform are examined and substantiated. Theoretical and practi-cal significance of the results. The theoretical significance consists in supplementing pedagogical knowledge with ideas about modern methods and techniques for creating creativity among schoolchil-dren β cases, test cards and reference schemes based on a given structure. The practical significance of the study lies in the fact that a technique has been developed that can be useful in the formation of cre-ative abilities in conditions of additional education. Substantive findings of the study: creative abilities are examined and their essence is revealed, the pedagogical potential of the Arduino platform is de-scribed in the formation of creative abilities among students, on the one hand, and on the other hand, in the possibilities of working on technically and commercially significant projects. The pedagogical poten-tial of the Arduino platform lies in the great opportunities for creative innovation in robotics lessons, as well as in the combination of programming fundamentals with engineering activities, during which ap-plied technical problems are solved.ΠΡΠΎΠ±Π»Π΅ΠΌΠ° ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ: ΠΊΠ°ΠΊ ΠΏΠΎΠ²ΡΡΠΈΡΡ ΡΡΡΠ΅ΠΊΡΠΈΠ²Π½ΠΎΡΡΡ ΡΠΎΡΠΌΠΈΡΠΎΠ²Π°Π½ΠΈΡ ΠΊΡΠ΅Π°ΡΠΈΠ²Π½ΡΡ

Emergency control algorithm for maintaining power stability based on newton's method
The problem of stability boundary evaluation for the current power system state is of paramount importance for power system operation. In addition, maintaining stability after large scale disturbances has come to the fore in recent years. This paper presents the algorithm, which allows us to both evaluate the stability boundary of a power system and to calculate emergency control actions for maintaining stability in the case of blackout. The algorithm is based on Newton's method for solving optimization problems. There are a number of emergency actions algorithms in literature, but most of them use heuristic rules. On the contrary, the proposed method has a reasonable analytical background. Thus, having an adequate power system model, the proposed method is able to calculate more accurate control actions. The paper demonstrates the very basic idea of the approach with the simplest example.

Electric Dipole Moments of Leptons in the Presence of Majorana Neutrinos
We calculate the two-loop diagrams that give a non-zero contribution to the
electric dipole moment d_l of a charged lepton l due to possible Majorana
masses of neutrinos. Using the example with one generation of the Standard
Model leptons and two heavy right-handed neutrinos, we demonstrate that the
non-vanishing result for d_l first appears in order O(m_l m_\nu^2 G_F^2), where
m_\nu is the mass of the light neutrino and the see-saw type relation is
imposed. This effect is beyond the reach of presently planned experiments.Comment: 13 page
Sensitivity of CPT Tests with Neutral Mesons
The sensitivity of experiments with neutral mesons to possible indirect CPT
violation is examined. It is shown that experiments conventionally regarded as
equivalent can have CPT reaches differing by orders of magnitude within the
framework of a minimal CPT- and Lorentz-violating extension of the standard
model.Comment: 4 pages REVTeX, published in Physical Review Letter

Large-scale Samples Irradiation Facility at the IBR-2 Reactor in Dubna
The irradiation facility at the beam line no.3 of the IBR-2 reactor of the Frank Laboratory for Neutron Physics is described. The facility is aimed at irradiation studies of various objects with area up to 800 cm both at cryogenic and ambient temperatures. The energy spectra of neutrons are reconstructed by the method of threshold detector activation. The neutron fluence and dose rates are measured by means of alanine and thermoluminescent dosimeters. The boron carbide and lead filters or converter provide beams of different ratio of doses induced by neutrons and photons. For the lead filter, the flux of fast neutrons with energy more than 0.1 MeV is \fln and the neutron dose is about 96\% of the total radiation dose. For the converter, the dose rate is 500 Gy h which is about 85\% of the total dose. The radiation hardness tests of GaAs electronics and materials for the ATLAS detector to be put into operation at the Large Hadron Collider (LHC) have been performed successfully at this facility
Model-Based Design of Kinematics and Dynamics of Universal Joints in Technological Machines
The study implements a mathematical and visual analysis of the universal joint's work in the software package MathCad and MATLAB Simulink. We obtained the dynamic model taking into account internal characteristics. It demonstrates the connection of the torque on the crosspiece with the angular velocity of the driveshaft and allows to find and fix errors in the early stages of design.
