Hop-by-hop interest shaping has been proposed as a viable congestion control mechanism in Named Data Networking (NDN). Interest shaping exploits the strict receiver-driven traffic pattern and the symmetric bidirectional forwarding in NDN to control the returning data rate. In this paper, we point out that both interests and contents contribute to congestion(More)
—We introduce a rate-based congestion control mechanism for Content-Centric Networking (CCN). It builds on the fact that one Interest retrieves at most one Data packet. Congestion can occur when aggregate conversations arrive in excess and fill up the transmission queue of a CCN router. We compute the available capacity of each CCN router in a distributed(More)
The effects of arachidonic acid (AA) on the development of viral infection and the activity of phytohemagglutinins in Nicotiana tabacum L. plants were studied. Cv. Samsun NN was used, which displayed a genotypically determined hypersensitive response to tobacco mosaic virus (TMV) infection. When tobacco leaf disks were treated with 10–9 to –10–7 M AA, viral(More)
The data concerning the plant sex regulation by phytohormones are presented. Functioning of signaling pathways regulating floral development and sex expression, including those with phytohormone involvement, are considered. The role of phytohormones in the functioning of systems and mechanisms of sex regulation is analyzed. The examples of sex reversion by(More)
The mechanisms of the protective, immunostimulating effects of arachidonic acid (AA) were studied, and its efficiency in the induction of defense reactions in the moderately virus-resistant potato cultivar Nevskii (Solanum tuberosumL.) was determined. Virus-free in vitropotato plants treated with AA and inoculated with phytopathogenic viruses were used as a(More)
Tube-grown potato (Solanum tuberosum L., cv. Nevskii) plants treated with arachidonic acid (AA) were used as a model to study the activity of phytohemagglutinins (PHA) during induction of the plant antiviral defense system. Plant treatment with 10–8 M AA and also their inoculation with potato viruses X, Y, and M resulted in the increased activity of PHAs in(More)
Generation of peroxy radicals, which cause destructive processes in the cell membrane, has been implicated in the pathogenesis of viral diseases in plants [1]. In this context, of particular interest is an idea that antioxidants can be used therapeutically to inhibit lipid peroxidation. Ubiquinones are lipids with antioxidant properties. Conceivably,(More)
Based on RAPD-PCR analysis with 15 primers including those homologous to particular loci, the level of genetic polymorphism in the collection of spring common wheat genotypes and their androclinal double haploid (ADH) lines was determined. Intraspecific polymorphism of the original wheat forms was 20%. By the absence of polymorphism in the molecular(More)
Changes in the phytohormonal system during the development of antivirus resistance was investigated. This resistance was induced by arachidonic acid (AA) in potato plants (Solanum tuberosum L.) grown in vitro. The plants in tubes were treated with AA 7 days before infection with tobacco mosaic virus or potato X virus. These plants were used for ABA, IAA,(More)
The most significant theories of the appearance and maintenance of sex are presented. However, in the overwhelming majority of existing theories, the problem of sex, which is the central problem of evolutionary biology, is considered primarily through the prism of reproductive features of living organisms, whereas the issue of molecular driving forces of(More)
