Subcarrier Wave Quantum Key Distribution in Telecommunication Network with Bitrate 800 kbit/s

In the course of work on creating the first quantum communication network in Russia we demonstrated quantum key distribution in metropolitan optical network infrastructure. A single-pass subcarrier wave quantum cryptography scheme was used in the experiments. BB84 protocol with strong reference was chosen for performing key distribution. The registered sifted key rate in an optical cable with 1.5 dB loss was 800 Kbit/s. Signal visibility exceeded 98%, and quantum bit error rate value was 1%. The achieved result is a record for this type of systems

Position-Sensitive MCP-based Detectors with High Timing Resolution: Some Results and Perspectives

The microelectronic design and some results of experimental tests of three types of coordinate sensitive Micro-Channel-Plate (MCP)-based detectors with high timing properties are presented. The electrodynamic structures that could be used for the MCP fast signal readout (strips, delay lines and discrete pads) are always a compromise between the amplitude of the induced signal, propagation time delay, cross-talk and distortions of the signal at the output. In-lab tests of these structures and experimental tests of the detectors done with the beams of MIPs and with the alpha-source have shown the 130 microns spatial and 110 ps timing resolution obtained simultaneously for one detector

An XPS method for layer profiling of NbN thin films

Layer chemical and phase profiling of niobium nitride thin films on a silicon substrate oxidized on air was performed with the help of a method designed by us. The method includes: a new method of background subtraction of multiple inelastically scattered photoelectrons considering depth inhomogeneity of electron inelastic scattering; a new method of photoelectron line decomposition into component peaks considering physical nature of different decomposition parameters; joint solution of the background subtraction and photoelectron line decomposition problems; control of line decomposition accuracy with the help of a suggested performance criterion; calculation of layer thicknesses for a multilayer target using a simple formula

Management of adherence-based treatment. Consensus document – Clinical guidelines. English version [упРАВЛЕНИЕ ЛЕЧЕНИЕМ НА ОСНОВЕ пРИВЕРЖЕННОСТИ. КОНСЕНСуСНЫй ДОКуМЕНТ – КЛИНИЧЕСКИЕ РЕКОМЕНДАЦИИ. АНГЛОЯзЫЧНАЯ ВЕРСИЯ]

Consensus Document «Management of adherence-based treatment» developed based on clinical guidelines of Russian Scientific Medical Society of Internal Medicine approved by the XIV National Congress of physicians (Moscow, 20 November 2019). The document is intended primarily to assess adherence to drug therapy, adherence to lifestyle modification, and adherence to medical support for patients who need long-term or permanent treatment. The document’s authors considered the treatment adherence unanimously as the compliance of the patient’s behavior with the recommendations received from the Doctor regarding medication, dieting, and other measures of lifestyle modifications. Insufficient adherence to treatment is a global problem. Assessing adherence as a basis for making medical decisions is an essential element of improving the quality of the healthcare system. Predictions of treatment outcomes cannot be considered effective if individualized levels of adherence are not used to justify project planning and evaluation. In medical practice, quantitative assessment of adherence is preferred, suitable for patients with various diseases, and with the possibility of automated data entry and processing. Therefore, sections on medical interventions based on the assessment of treatment adherence should be reflected in national clinical guidelines. These Joint Recommendations are based on these provisions. © Group of authors, 202
