We propose an approach for the excitation of polariton Tamm states with a controllable nontrivial topology. The polaritons emerge at interface two binary one-dimensional photonic crystals belonging to ${C}_{3v}$ point group, exciton resonance within their matching band gaps. external magnetic field applied in Faraday geometry endows dispersion nonreciprocity: it lifts degeneracy between opposit...

It is shown that thermal flow sensors are characterized by high structural and technological compatibility with biomedical equipment and, compared to other types of sensors, they most fully meet the requirements for this equipment. The developed signal converters modern energy-saving low-voltage electronics (unipolar 3V power supply), provide a negligible effect on environment implemented lates...

Group-theoretical methods are used to show that inverted torsional splittings in fundamental levels of small-amplitude vibrations of methanol-like molecules can be parameterized and understood in terms of the energy level patterns induced when a pair of high-barrier torsionally split components of given v(t) and (t)A+(t)E symmetry species in the molecular symmetry group G(6) is allowed to inter...

The effects of intracerebroventricular application of melanin-concentrating hormone (MCH) on licking for sucrose, quinine hydrochloride (QHCl), and water solutions were evaluated in two experiments. In experiment 1, rats received 90-min access to sucrose and water solutions after MCH or vehicle microinjection to the third ventricle (3V). MCH increased intake largely through increases in the rat...
