Music Tune Restoration Based on a Mother Wavelet Construction

It is offered to use the mother wavelet function obtained from the local part of an analyzed music signal. Requirements for the constructed function are proposed and the implementation technique and its properties are described. The suggested approach allows construction of mother wavelet families with specified identifying properties. Consequently, this makes possible to identify the basic signal variations of complex music signals including local time-frequency characteristics of the basic one

Epidemiological Characteristics of Enterovirus Infection in the Khabarovsk Territory under Hydrologic Emergency Situation

The paper contains the data on the role of high waters (2013) in changing epidemiological situation on enterovirus infections in the Khabarovsk Territory. The incidence rate in the region was characterized by the significant increase even before the flood, 2013. Thus, two peaks of enterovirus morbidity curve were identified for the period of a week: one - more intensive, another - coincident with flood outbreak. Enterovirus epidemiological process was notified by the changes in clinical picture among the infected population and cohort age-related structure. The percentage of the patients with enterovirus infections in the foci clusters and the index of people infected due to possible exposure to shattering impact of the flood, turned out to be low. However, revealed was high rate of heterogeneity of the circulating enterovirus strains, non-specific for the Khabarovsk territory and mostly originating from countries of Asia-Pacific region - coxsackie A viruses, which might stand for a possible cause of unfavorable epidemiological situation in 2013

Multiannual Analysis of Epidemiological Process Manifestations as Regards Enteroviral Infection in the Khabarovsk Territory, and the Key Factors that Predetermine Aggravation of Epidemiological Situation under the Terms of Flood

Carried out has been retrospective analysis of epidemiological process manifestations as regards enteroviral infection in the Khabarovsk Region over the period of 7 years, prior to rainfall floods in 2013. Revealed is the possibility of aggravation of epidemiological situation during hydrological emergency situation. The premises are as follows: persistent due to specific climate conditions prevalent in the Khabarovsk Territory (high air and surface water temperatures, and high humidity rates) unfavorable epidemiological situation on enteroviral infections, virus-carriage in “healthy” people and extensive dissemination of enteroviruses in the water bodies of ambient environment. Moreover, widespread circulation of different enterovirus genotypes, including the isolates with high genetic similarity to the strains identified earlier in the adjoining People’s Republic of China, takes place
