Abstract Alias resolution, mapping IP addresses to routers, is a critical step in obtaining a network topology. The latest work on alias resolution is based on special fields in the packet, such as IP ID, port number, etc. However, for security reasons, most network devices block packets for setting options, and some related fields exist only in IPv4, so these methods cannot be used for alias resolution of IPv6. In order to solve the above problems, we propose an alias analysis method based on delay sequence analysis. In this article, we present a new model to describe the distribution of Internet… More >

Abstract Cerasus Campanulata is one of several species belonging to the Prunoideae focke, a subfamily of the flowering plant Rosaceae. We investigated the details of its chloroplast genome which may reveal its genus independent of morphological determination. Here, we determined the complete chloroplast (cp) genome sequence of C. campanulata and performed sequence analysis to reveal the presence of 18 forward repeats, 20 palindrome repeats, 2 complement repeats, 4 reverse repeats and 93 simple sequence repeats (SSRs). We additionally performed a comparative study of C. campanulata and seven other Prunoideae focke species. Then, maximum parsimony (MP) and maximum likelihood (ML) phylogenetic analyses… More >

Abstract Bacterial artificial chromosome - fluorescence in situ hybridization (BAC-FISH) and cyclingprimed in situ labeling (C-PRINS) techniques were evaluated for integration of physical and genetic maps of sunflower (Helianthus annuus L.). Single-site SSR markers were selected from three linkage groups of a high-density sunflower genetic map. This selection was based on previously identified QTL associated to S. sclerotiorum. These markers were used to select BACs contaning single copy sequences for BAC-FISH aplication. Blocking of highly dispersed repetitive sunflower sequences reduced unspecific hybridization, and allowed the detection of specific signals for BACs containing SSR markers HA4222 and HA2600, anchored to LG 16… More >

Abstract Secreted arginases from Evernia prunastri and Xanthoria parietina thalli, exhibiting lectin activity, have been purified to homogeneity. Analyses of both amino acid and glycoside composition are reported. Purified proteins have been subjected to tryptic digestion and some amino acid sequences have been analyzed. An undecapeptide from Evernia arginase, which shows some degree of homology with the domain to which Mn²⁺ binds, a heptapeptide and an undecapeptide from Xanthoria arginase have been analyzed, and homologies with some arginases from other fungi and plants have been found.

Abstract Dehydrins or Group 2 Late Embryogenesis Abundant (LEA) proteins play an important role in the response and adaptation to different types of abiotic stresses such as droughts, high salinity and low temperatures. Using PCR techniques, we identified three gene fragments that encoded dehydrin-like proteins in three cactispecies Opuntia ficus-indica (OpfiDHN-like), Leuchtenbergia principis (LepDHN-like) and Mammillaria bombycina (MabDHN-like). Bioinformatic sequence analysis showed an identity between 96 and 97% with the Opuntia streptacantha dehydrin 1 (OpsDHN1) gene, demonstrating that the amplified fragments corresponded to dehydrin-like gene sequences, and that the designed oligonucleotides were effective for similar gene amplification in different cacti genera.… More >

Abstract In plants, the mitochondrial NADH dehydrogenase (complex I) is a large protein complex transferring electrons to ubiquinone. For the nine chondriogenes encoding complex I subunits (nad1, nad2, nad3, nad4, nad4L, nad5, nad6, nad7, and nad9), an efficient strategy for the cloning of complete coding sequences (CDSs) is important. Specific orthologous portions of untranslated regions (UTRs) were found based on multiple sequence alignments of chondriogene orthologues encoding complex I subunits in plant species. Based on the conservation of partial UTRs, a one-step PCR strategy was conceived for the cloning of CDSs of the nine chondriogene orthologues. Using this strategy, the five… More >

Abstract On Twitter, people often use hashtags to mark the subject of a tweet. Tweets have specific themes or content that are easy for people to manage. With the increase in the number of tweets, how to automatically recommend hashtags for tweets has received wide attention. The previous hashtag recommendation methods were to convert the task into a multi-class classification problem. However, these methods can only recommend hashtags that appeared in historical information, and cannot recommend the new ones. In this work, we extend the self-attention mechanism to turn the hashtag recommendation task into a sequence labeling task. To train and… More >

Abstract Cyanobacteria are phototrophic organisms with great ecological and economical importance. Species of the genus Microcystis are known for their potential ability to synthesize toxins, notably microcystins. There is a growing interest in the evaluation of oxidative stress in relation to the impact of global climate change on natural ecosystems in different trophic levels. Several studies have focused on the analysis of organismal responses to mitigate the damage by controlling the generation of reactive oxygen species. Variations in environmental factors caused by climate change generate a situation of oxidative damage in Microcystis aeruginosa as a direct or indirect consequence. In this… More >

Abstract Barley (Hordeum vulgare L.) is one of the most Aluminum (Al) sensitive cereal species. In this study, the physiological, biochemical, and molecular response of barley seedlings to Al treatment was examined to gain insight into Al response and tolerance mechanisms. The results showed that superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) activity were inhibited to different degrees following Al exposure. The MDA content also significantly increased with increasing Al concentrations. SRAP results indicated significant differences between Al treatments and controls in terms of SRAP profile, and the genomic template stability (GTS) decreased with increasing Al concentration and duration. These… More >
