    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 – 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.ΠŸΡ€ΠΎΠ±Π»Π΅ΠΌΠ° исслСдования: ΠΊΠ°ΠΊ ΠΏΠΎΠ²Ρ‹ΡΠΈΡ‚ΡŒ ΡΡ„Ρ„Π΅ΠΊΡ‚ΠΈΠ²Π½ΠΎΡΡ‚ΡŒ формирования ΠΊΡ€Π΅Π°Ρ‚ΠΈΠ²Π½Ρ‹Ρ… способностСй школьников Π² условиях Π΄ΠΎΠΏΠΎΠ»Π½ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠ³ΠΎ образования.

    R-parity violating supersymmetric contributions to the P, CP-odd electron-nucleon interaction at the one-loop level

    Full text link
    The contribution of the R-parity violating minimal supersymmetric Standard model (RPVMSSM) at the one-loop level to the 199Hg atomic electric dipole moment (EDM) through P, CP-odd electron-nucleon (e-N) interaction is calculated. We show that the current experimental data of the 199Hg EDM give tighter constraints on some of the imaginary parts of R-parity violating (RPV) coupling than those currently known. We add also the analysis of the P, CP-odd 4-quark interaction generated by R-parity violating interactions at the one-loop level, and discuss the possibility to constrain them in future experiments.Comment: 9 pages, 3 figure

    Scalar meson dynamics in Chiral Perturbation Theory

    Full text link
    A comparison of the linear sigma model (Lσ\sigmaM) and Chiral Perturbation Theory (ChPT) predictions for pion and kaon dynamics is presented. Lowest and next-to-leading order terms in the ChPT amplitudes are reproduced if one restricts to scalar resonance exchange. Some low energy constants of the order p4p^4 ChPT Lagrangian are fixed in terms of scalar meson masses. Present values of these low energy constants are compatible with the Lσ\sigmaM dynamics. We conclude that more accurate values would be most useful either to falsify the Lσ\sigmaM or to show its capability to shed some light on the controversial scalar physics.Comment: 9 pages, REVTeX 4.0.

    Charged Kaon K \to 3 pi CP Violating Asymmetries at NLO in CHPT

    Full text link
    We give the first full next-to-leading order analytical results in Chiral Perturbation Theory for the charged Kaon K \to 3 pi slope g and decay rates CP-violating asymmetries. We have included the dominant Final State Interactions at NLO analytically and discussed the importance of the unknown counterterms. We find that the uncertainty due to them is reasonable just for \Delta g_C, i.e. the asymmetry in the K^+ \to pi^+ pi^+ pi^- slope g; we get \Delta g_C = -(2.4 +- 1.2) 10^{-5}. The rest of the asymmetries are very sensitive to the unknown counterterms. In particular, the decay rate asymmetries can change even sign. One can use this large sentivity to get valuable information on those counterterms and on Im(G_8) coupling --very important for the CP-violating parameter epsilon'_K-- from the eventual measurement of these asymmetries. We also provide the one-loop O(e^2 p^2) electroweak octet contributions for the neutral and charged Kaon K \to 3 pi decays.Comment: 43+2 pages, 2 figures. Version accepted in JHEP.

    The neutron electric dipole form factor in the perturbative chiral quark model

    Full text link
    We calculate the electric dipole form factor of the neutron in a perturbative chiral quark model, parameterizing CP-violation of generic origin by means of effective electric dipole moments of the constituent quarks and their CP-violating couplings to the chiral fields. We discuss the relation of these effective parameters to more fundamental ones such as the intrinsic electric and chromoelectric dipole moments of quarks and the Weinberg parameter. From the existing experimental upper limits on the neutron EDM we derive constraints on these CP-violating parameters.Comment: 20 pages, 3 figure

    Spacial and temporal dynamics of the volume fraction of the colloidal particles inside a drying sessile drop

    Full text link
    Using lubrication theory, drying processes of sessile colloidal droplets on a solid substrate are studied. A simple model is proposed to describe temporal dynamics both the shape of the drop and the volume fraction of the colloidal particles inside the drop. The concentration dependence of the viscosity is taken into account. It is shown that the final shapes of the drops depend on both the initial volume fraction of the colloidal particles and the capillary number. The results of our simulations are in a reasonable agreement with the published experimental data. The computations for the drops of aqueous solution of human serum albumin (HSA) are presented.Comment: Submitted to EPJE, 7 pages, 8 figure

    Strong CP violation and the neutron electric dipole form factor

    Full text link
    We calculate the neutron electric dipole form factor induced by the CP violating theta-term of QCD, within a perturbative chiral quark model which includes pion and kaon clouds. On this basis we derive the neutron electric dipole moment and the electron-neutron Schiff moment. From the existing experimental upper limits on the neutron electric dipole moment we extract constraints on the theta-parameter and compare our results with other approaches.Comment: 18 pages, 2 figures, accepted for publication in Phys.

    The isospin symmetry breaking effects in Ke4K_{e4} decays

    Full text link
    The Fermi-Watson theorem is generalized to the case of two coupled channels with different masses and applied to final state interaction in Ke4K_{e4} decays. The impact of considered effect on the phase of the ππ\pi\pi scattering is estimated and shown that it can be crucial for scattering lengths extraction from experimental data on Ke4K_{e4} decays
