    Thermal non-equilibrium effects in quantum reflection

    Full text link
    We show that the quantum reflection coefficient of ultracold heavy atoms scattering off a dielectric surface can be tuned in a wide range by suitable choice of surface and environment temperatures. This effect results from a temperature dependent long-range repulsive part of the van der Waals-Casimir-Polder-Lifshitz atom-surface interaction potential

    Optical and evaporative cooling of cesium atoms in the gravito-optical surface trap

    We report on cooling of an atomic cesium gas closely above an evanescent-wave atom mirror. At high densitities, optical cooling based on inelastic reflections is found to be limited by a density-dependent excess temperature and trap loss due to ultracold collisions involving repulsive molecular states. Nevertheless, very good starting conditions for subsequent evaporative cooling are obtained. Our first evaporation experiments show a temperature reduction from 10muK down to 300nK along with a gain in phase-space density of almost two orders of magnitude.Comment: 8 pages, 6 figures, submitted to Journal of Modern Optics, special issue "Fundamentals of Quantum Optics V", edited by F.

    The authors consider the discourse of a glossy magazine. They highlight the glossy magazine discourse, which appears in the framework of the General media discourse as an institutional discourse from the standpoint of the linguistical-rhetorical paradigm (LRP) of the Sochi scientific school. This type of discourse is a discursive process of a special type, acts as an explicit tool of globalization. The authors emphasize the novelty of this discourse in the context of its influence on the formation and transformation of the modern linguistic personality. The relevance of the study is emphasized by the fact that the glossy magazine discourse is the latest in terms of the chronology of the historical process. In addition, he actualizes the poly-ethno-socio-cultural and educational space (PESCES) of the beginning of the XXI century, on the example of glossy magazine discourse practices in Russia. For the first time, Glossy magazine discourse stimulates transformations in line with the leading trend of the formation of the "planetary language personality (PLP)" - globalization in the value orientations of the "philosophy of glamour"

    In order to take part in the intercultural communication of students, an idea of ​​national traditions, cultural values, customs, and realities of the studied language country must be developed. Lacunae are the gaps in knowledge of the country and the people culture who speak the language being studied. When you work with lacunae, it is necessary to check the correct understanding of their meaning constantly, as well as introduce them into the active vocabulary of students. This is why this study seeks to address the sociocultural gaps and the ways of transfer during the study of foreign languages.Para participar en la comunicación intercultural de los estudiantes, se debe desarrollar una idea de las tradiciones nacionales, los valores culturales, las costumbres y las realidades del país de la lengua estudiada. Las lagunas son las lagunas en el conocimiento del país y la cultura de las personas que hablan el idioma que se estudia. Cuando trabajas con lagunas, es necesario verificar constantemente la comprensión correcta de su significado, así como introducirlos en el vocabulario activo de los estudiantes. Es por esto que este estudio busca tratar la Brechas socioculturales y las formas de su eliminación durante el estudio de lenguas extranjera

    Development of an Intellectual Educational and Diagnostic Complex for the Histological Analysis of Thyroid Tumors

    Get PDF
    The purpose of this project is the creation of an interactive intellectual training system based on the DBMS, which allows to organize and store information, transfer and copy data for employees. The already existing images and their characteristics are structured, a decision support system is developed for the recognition of tumors and suspicious cells, which saves time for an already experienced oncologist. This system allows to increase the accuracy of diagnosis. Educational and diagnostic complexes help to accumulate experience for young specialists in the field of image analysis, carry out comparative research, which speeds up the learning process, promotes professional development of the specialist.

    The article presents the rationale and definition of the parameters of cognitive engagement of students in pedagogical areas of training that optimize the design of educational activities at the university, the results of assessing the quality of the educational process in the preparation of bachelors in the direction of “Pedagogical education” at the Tambov State University named after G.R. Derzhavin and Moscow State Regional University based on the application of the integral criterion of students’ cognitive engagement.The article analyzes foreign and domestic research in the field of “cognitive engagement”, the best practices for monitoring the engagement of students in other areas at the Higher School of Economics, MEPhI, at the universities of the USA, identifies the main indicators and defines an integral criterion for the cognitive engagement of students in pedagogical areas based on their coordination with the cognitive mode learning activities and cognitive strategies of students, as well as the experience of diagnosing the cognitive engagement of student teachers.The results of the study presented in the article are the basis for improving the efficiency and effectiveness of the activities of university departments that provide training of teaching staff by means of designing the educational process with high cognitive engagement of students. The developed diagnostic and technological tools can be used to manage, design, assess the quality of pedagogical activity, the educational result of a student and develop priority educational modes of training, learning technologies in higher pedagogical education, and can also serve as the basis for monitoring conducted by quality assessment units, auditing educational innovation at the university
