Intelligent OFDM telecommunication system. Part 4. Anti-eavesdropping and anti-jamming properties of the system, based on many-parameter and fractional Fourier transforms
In this paper, we aim to investigate the superiority and practicability of many-parameter wavelet and Golay transforms (MPWT and MPGT) from the physical layer security (PHY-LS) perspective. We propose novel Intelligent OFDM-telecommunication system (Intelligent-OFDM-TCS), based on many-parameter transforms (MPTs). New system uses inverse MPT for modulation at the transmitter and direct MPT for demodulation at the receiver. The purpose of employing the MPTs is to improve the PHY-LS of wireless transmissions against to the wide-band anti-jamming communication. Each MPT depends on finite set of independent Jacobi parameters (angles), which could be changed independently one of another. When parameters are changed, multi-parametric transform is changed too taking form of a set known (and unknown) orthogonal (or unitary) wavelet transforms. We implement the following performances as bit error rate (BER), symbol error rate (SER), peak to average power ratio (PAPR), the Shannon-Wyner secrecy capacity (SWSC) for novel Intelligent-MPWT-OFDM-TCS. Previous research has shown that the conventional OFDM TCS based on discrete Fourier transform (DFT) has unsatisfactory characteristics in BER, PARP, SWSC and in anti-eavesdropping communications. We study Intelligent-MPT-OFDM-TCS to find out optimal values of angle parameters of MPT optimized BER, PAPR, SWSC, anti-eavesdropping effects. Simulation results show that the proposed Intelligent OFDM-TCS have better performances than the conventional OFDM system based on DFT against eavesdropping. Β© 2019 IOP Publishing Ltd.

The objective: to study the long-term changes (1991-2020) in tuberculosis mortality in population of Altai Kray and assess the impact of certain categories of citizens on the formation of this rate.Subjects and Methods: Statistical Forms no. 8, 30, and 33, statistical compilations, and medical scientific publications.Results. In order to analyze the curves reflecting changes in tuberculosis mortality in Altai Kray and Russia, these curves have been divided into three conventional periods. General trends have been identified but there are some peculiarities: a significant excess of the average longterm value of the rate versus this rate for whole of Russia; this rate increased faster in the conventional period of 1991-2005. Using the statistical method, it has been established that the formation of tuberculosis mortality rate in the population of Altai Kray was influenced by tuberculosis mortality rate in the Federal Penitentiary Service in 1997 and 1998 and in homeless people in 2005-2008.Π¦Π΅Π»Ρ: ΠΈΠ·ΡΡΠΈΡΡ ΠΌΠ½ΠΎΠ³ΠΎΠ»Π΅ΡΠ½ΡΡ Π΄ΠΈΠ½Π°ΠΌΠΈΠΊΡ (1991-2020 Π³Π³.)

Destructive lung tuberculosis is a heterogeneous group of various forms of the lung tuberculosis (recent, chronic, advanced) which have common features, such as the presence of cavities, a presence of Mycobacteria tuberculosis and they are hard for treatment. Peculiarities of the microcirculation, the fibrous capsule outside the cavity, the caseous and necrotizing layer inside impede medications to reach the inflammation and destruction zone when applied as intranasal as directly into the cavity. Techniques for drug delivery to the perifocal zone (needle-jet injections, intrapulmonary ionophoresis), dΓ©naturation of the cavityβs pyogeneous layer (hydrodiathermocoagulation) and damming of the draining bronchi (blocking of the cavity) allow to increase a number of the destructive cavities closed 23-43.3% more and to eradicate the Mycobacteria tuberculosis 33-47.5% more copared with a complex conservative treatment.ΠΠ΅ΡΡΡΡΠΊΡΠΈΠ²Π½ΡΠΉ ΡΡΠ±Π΅ΡΠΊΡΠ»Π΅Π· Π»Π΅Π³ΠΊΠΈΡ

Diagnostic value of immunological skin tests in children with tuberculosis
The paper gives the results of an analysis of intracutaneous Mantoux tuberculin tests with 2 TU, 1 TU, 0.1 TU, and 0.01 TU PPD-L and intracutaneous Diaskintest using recombinant tuberculosis allergen in the standard dilution in 63 children with tuberculosis. A moderate correlation was found between the results of the above tests. There was the highest sensitivity of the immune system to the administration of 0.01 TU PPD-L (0.0006 Β΅g). A high specific responsiveness as a hyperergic reaction was established when recombinant tuberculosis allergen was used in standard dilution (0.2 Β΅g). There were moderately intensive and weakly positive reactions (10-14- and 5-9-mm infiltrates) to the administration of 2 TU (0.12 Β΅g) of tuberculin in the skin test. The tuberculin skin test with 0.01 TU PPD-L was ascertained to be of more significant diagnostic value than the Diaskintest using recombinant tuberculosis allergen in standard dilution

Modern opportunities for optimising the treatment of patients with coronary heart disease and arterial hypertension: role of zofenopril
The wide prevalence (82%) of coronary heart disease (CHD) in combination with arterial hypertension (AH), as well as its initiating role in the development of fatal complications, such as myocardial infarction (MI) or heart failure, emphasise the need for the choice of optimal ACE inhibitors with organ-protective characteristics. This paper presents a literature review on the effectiveness of a SH-containing ACE inhibitor zofenopril in patients with CHD and AH, in terms of its anti-anginal and antihypertensive activity. The authors summarise the results of the international SMILE studies which included patients after acute MI. It was demonstrated that zofenopril therapy is associated with reduced combined incidence of cardiovascular death or cardiovascular hospitalisation, and is also safe in the acute post-MI period. In patients with preserved left ventricular function, zofenopril reduced the incidence of angina attacks and arrhythmias of coronary genesis, as well as improved exercise capacity. A clinical case of zofenopril therapy, as a part of a complex treatment regimen, is also presented
