Radio emission of sea surface at centimeter wavelengths and is fluctuations

The eigen thermal radio emission of the sea was examined as well as the agitated surface of the sea when the reflection (scattering) is similar in nature to diffused scattering. The contribution of this emission to the total emission of the sea is practically constant in time, and the time fluctuations of the radio emissions of the sea are basically determined only by a change in the eigen emission of the sea, connected with the agitation

SATELLITE SIGNAL DETECTION METHOD BASED ON MODIFICATION COMPRESSION OPERATOR

The modification of compression operator on the basis of polynomial approximation with analytic connection has been proposed. The approximation of two discrete sequences between determinated bases with analytical relation has been reviewed. The characteristics of meander signal have been built with a help of classic and proposed method

Equivalents of the neutrophil-to-lymphocyte ratio of circulating pool of stem and immature hematopoietic cells for assessing liver transplant status

Objective: to study the applicability of the neutrophil-to-lymphocyte ratio (NLR) for monitoring recipient status and for possible minimization of maintenance immunosuppression in the long-term period after liver transplantation (LT).Materials and methods. Blood samples of 19 recipients with satisfactory graft function were examined by flow cytofluorometry at various time periods after LT using hematopoietic stem cell markers CD133, their CD31 derivatives, and alpha-fetoprotein (AFP), compared with the conventional NLR.Results. The use of NLR equivalents with CD133 and CD31 to assess liver transplant status is due to their high representation in liver tissue. Their values change in the long-term posttransplant period (from 1.5 to 6–7 years following LT) ≈20-fold and in different directions, but only when measuring their commissural to the liver cell fractions bearing the AFP marker.Conclusion. In contrast to the conventional NLR, maintenance of the lowest level of CD31 AFP, an NLR «equivalent», achieved at 1.5 years after LT, can be considered a criterion for the success of immunosuppressive therapy in the long-term post-LT period. The developed technique can be used to decide on whether to reduce or discontinue medication-assisted prophylaxis of graft rejection

Efficiency of the Algorithm for Previous Detection of the State of a Transmitting Laser Means Based on Reception and Analysis of Non- Stationary Pre- Generation Spontaneous Radiation

Предложен алгоритм обнаружения оптическим приемником полезного сигнала, представляющего собой нестационарное, возрастающее на некотором интервале излучение в пуассоновских шумах, имеющих стационарный характер. Оценена эффективность алгоритма с учетом реализации процесса взвешенного суммирования принимаемого входного сигнала, представляющего аддитивную смесь полезного и шумового излучений в режиме накопления. Получены аналитические выражения с оценкой основных характеристик (среднего и дисперсии) суммированных неравномерных взвешенных отсчетов с выхода сумматора и функции распределения предпорогового воздействия для различных гипотез. Для рассматриваемого случая оценены условные вероятности правильного обнаружения ложной тревогиAn algorithm for detecting a useful signal by an optical receiver, which is a non- stationary radiation increasing over a certain interval in Poisson noises of a stationary nature, is proposed. The efficiency of the algorithm is estimated taking into account the implementation of the process of weighted summation of the received input signal, which is an additive mixture of useful and noise radiation in the accumulation mode. Analytical expressions are obtained with an estimate of the main characteristics (average and dispersion), summed non- uniform weighted readings from the adder output and the distribution function of the pre-threshold effect for various hypotheses. For the case under consideration, the conditional probabilities of correct detection of a false alarm are estimate

Long-Term Monitoring of Liver Fibrosis and Steatosis in Patients with Chronic Hepatitis C after Achieving a Sustained Virologic Response to Antiviral Therapy

Aim: to analyze the dynamics of fibrosis and steatosis of the liver according to fibroelastometry in patients with chronic hep-atitis C (CHC) after ≥ 6 months from transient elastometry (TE) achieving a sustained virologic response (SVR) to antiviral therapy.Materials and methods. At baseline, a prospective observational study included 628 CHC patients with known stage of liver fibrosis (F) before AVT, some of whom were phased out due to non-compliance with the inclusion criteria. The final analysis included 297 patients who had transient elastometry (TE) data with CAP™ technology on the severity of liver fibrosis (± steatosis) before treatment and after ≥ 6 months after reaching SVR (67 % – interferonfree regimens of therapy). Median follow-up from the moment SVR was confirmed was 3 years [2; 6].Results. At the end of the study, the average age of patients was 49 ± 12 years, of which 53 % were men. In the long-term period after reaching SVR, regression of liver fibrosis was diagnosed in 80 % of cases (including in patients with cirrhosis), and the progression of fibrosis was in 3 % of patient. At the same time, regression of liver steatosis was detected only in 31 % of the patient, worsening of the results was in 23 % (26 % of them had the appearance of steatosis (S) of the liver of 1–3 degrees in persons with no fatty liver before the start of AVT). In the group of patients with liver steatosis, the proportion of men was significantly higher (p = 0.004). Clinically significant stages of fibrosis F3–F4 were significantly more often recorded in patients with hepatic steatosis, both before treatment (46 % S1–S3 and 22 % S0, p < 0.001) and after ≥ 6 months after reaching SVR (19 % S1–S3 and 9 % S0, p = 0.023).Conclusion. In patients with chronic hepatitis C with SVR achieved in the long term, despite a significant regression of liver fibrosis, a high prevalence of hepatic steatosis remains. The data obtained indicate the feasibility of routine diagnosis of both fibrosis and steatosis of the liver in the management of patients with chronic HCV infection before and after successful antiviral therapy
