Evolution of Propagating Coherent Pulses Driving a Single Superconducting Artificial Atom.

An electromagnetic wave propagating through a waveguide with a strongly coupled two-level superconducting artificial atom exhibits an evolving superposition with the atom. The Rabi oscillations in the atom result from a single excitation-relaxation, corresponding to photon absorption and stimulated emission from and to the field. In this study, we experimentally investigated the time-dependent behavior of the field transmitted through a waveguide with a strongly coupled transmon.

[Ways to improve the epidemiological surveillance for plague].

The paper deals with the plague epidemiological surveillance in natural foci and with the ways of its improvement. The diversity of methods currently used for surveillance ensures a satisfactory epidemic situation though the problem of plague control among rodents and hares in the natural foci remained unsettled. Therefore the main task of research and practical plague institutions in improving plague epidemiological surveillance in the natural foci is to provide further research evidence for the application of facilities and guidelines to control the carriers and vectors of plague, which can prevent the development of epizootics and reduce a risk for human infection in the enzootic areas.

[Experimental study of the pulmonary form of plague, tularemia and pseudotuberculosis].

There was revealed a regular reduction of plague, tularemia and pseudotuberculosis bacteria count in the lungs of guinea pigs the first 12 hours after aerosol infection. Generalization of the infectious process and associated septicemia occurred in pulmonary plague and pulmonary tularemia on the 1st-2nd day, and in pulmonary pseudotuberculosis - on the 4th-5th day. Limits of accumulation of the causative agents in the organs and the blood at various stages of the infectious process were established.
