A study on incremental mining of frequent patterns

Data generated from both the offline and online sources are incremental in nature. Changes in the underlying database occur due to the incremental data. Mining frequent patterns are costly in changing databases, since it requires scanning the database from the start. Thus, mining of growing databases has been a great concern. To mine the growing databases, a new Data Mining technique called Incremental Mining has emerged. The Incremental Mining uses previous mining result to get the desired knowledge by reducing mining costs in terms of time and space. This state of the art paper focuses on Incremental Mining approaches and identifies suitable approaches which are the need of real world problem.Keywords: Data Mining, Frequent Pattern, Incremental Mining, Frequent Pattern Minung, High Utility Mining, Constraint Mining

Assessment of genetic variability, heritability and genetic advance in soybean genotypes

Forty soybean genotypes were evaluated for two consecutive years kharif 2018 and 2019 to determine genetic variability, heritability (h2) and genetic advance (GA) for yield and other yield attributing traits. The pooled analysis of variance revealed significant variation among year and treatment for all characters studied. The interaction of year x treatment also showed a significant difference for most of the traits. RVSM2011-35 recorded the highest mean performance of seed yield/plant and a high value of oil content over the two years indicating that the genotype was found to be promising and could be recommended for Assam. In the case of oil content, NRC 148 showed the highest mean value and also a high value of mean seed yield/ plant over the two years. Range estimation showed wide values for most of the traits except plant height, the number of branches and pods/plant in comparison with the check. The estimates of phenotypic (PCV) and genotypic (GCV) coefficient of variation indicated that the values of PCV were slightly higher than GCV. The highest values of GCV and PCV were observed for seed yield/plant, the number of seeds/pod and oil content. Higher values of heritability (h2) coupled with high genetic advance (GA) were recorded for seed yield/plant, the number of seeds/pod, oil content, the number of branches, days to 50% flowering, plant height, the number of pods/plant, and 100 seed weight, suggesting that these characters could easily be modified or improved through simple selection

Geotechnical properties of the bank sediments along the Dhansiri River channel,Assam

The bank sediments along the extremely meandered Dhansiri River channel, a south bank tributary of the mighty Brahmaputra River, with erosion potentiality have been investigated to evaluate its certain geotechnical characteristics. The study has shown that the bank sediments are basically composed of CL and ML types of soil. These types of sediments are very much prone to liquefaction which in turn related to erosion susceptibility. The bank stability analysis has differentiated the studied stretch into unstable, at risk and stable zones. Most of the erosion affected zones along the channel reach under study are located within the unstable or at risk zones. The field study around Butalikhowa, Barguriagaon, Golaghat and Duchmuagaon areas along the channel with active erosion activity has supported our contention and practical utility of the present study. It is expected that such type of study will help in providing certain inevitable baseline information for various channel management practices for this extremely flood prone areas of Northeast India

Synthesis of Nio-nanoparticles on nanoporous clay matrix and catalytic transfer hydrogenation reaction

Ni°-nanoparticles of 0–8 nm were prepared in situ by impregnation of Ni(CH3COO)2 into the nanopores of modifiedmontmorillonite(Mt)followedbypolyolreduction.TheMtwasactivatedwithHClundercontrolled condition for generating desired pore sizes. The porous materials were characterized by XRD, TEM, SEM, UV–visible spectroscopy, FTIR and XPS analysis. N2 adsorption data revealed specific surface areas (BET) in the range of 296–548 m2/g, specific pore volumes of 0.4–0.6 cm3/g and pore diameters of 0–6.8 nm. XRD pattern of Ni°-nanoparticles revealed the formation of face centered cubic (fcc) lattice. These supported Nio-nanoparticles show efficient catalytic activity in transfer hydrogenation of acetophenone to 1phenylethanol with about 98% conversion, having nearly 100% selectivi

Single Molecule Analysis of Replicated DNA Reveals the Usage of Multiple KSHV Genome Regions for Latent Replication

Kaposi's sarcoma associated herpesvirus (KSHV), an etiologic agent of Kaposi's sarcoma, Body Cavity Based Lymphoma and Multicentric Castleman's Disease, establishes lifelong latency in infected cells. The KSHV genome tethers to the host chromosome with the help of a latency associated nuclear antigen (LANA). Additionally, LANA supports replication of the latent origins within the terminal repeats by recruiting cellular factors. Our previous studies identified and characterized another latent origin, which supported the replication of plasmids ex-vivo without LANA expression in trans. Therefore identification of an additional origin site prompted us to analyze the entire KSHV genome for replication initiation sites using single molecule analysis of replicated DNA (SMARD). Our results showed that replication of DNA can initiate throughout the KSHV genome and the usage of these regions is not conserved in two different KSHV strains investigated. SMARD also showed that the utilization of multiple replication initiation sites occurs across large regions of the genome rather than a specified sequence. The replication origin of the terminal repeats showed only a slight preference for their usage indicating that LANA dependent origin at the terminal repeats (TR) plays only a limited role in genome duplication. Furthermore, we performed chromatin immunoprecipitation for ORC2 and MCM3, which are part of the pre-replication initiation complex to determine the genomic sites where these proteins accumulate, to provide further characterization of potential replication initiation sites on the KSHV genome. The ChIP data confirmed accumulation of these pre-RC proteins at multiple genomic sites in a cell cycle dependent manner. Our data also show that both the frequency and the sites of replication initiation vary within the two KSHV genomes studied here, suggesting that initiation of replication is likely to be affected by the genomic context rather than the DNA sequences

Search for doubly charged Higgs boson production in multi-lepton final states with the ATLAS detector using proton-proton collisions at √s = 13TeV

A search for doubly charged Higgs bosons with pairs of prompt, isolated, highly energetic leptons with the same electric charge is presented. The search uses a proton–proton collision data sample at a centre-of-mass energy of 13 TeV corresponding to 36.1 fb −1 of integrated luminosity recorded in 2015 and 2016 by the ATLAS detector at the LHC. This analysis focuses on the decays H±±→e±e±, H±±→e±μ± and H±±→μ±μ±, fitting the dilepton mass spectra in several exclusive signal regions. No significant evidence of a signal is observed and corresponding limits on the production cross-section and consequently a lower limit on m(H±±) are derived at 95% confidence level. With ℓ±ℓ±=e±e±/μ±μ±/e±μ±, the observed lower limit on the mass of a doubly charged Higgs boson only coupling to left-handed leptons varies from 770 to 870 GeV (850 GeV expected) for B(H±±→ℓ±ℓ±)=100% and both the expected and observed mass limits are above 450 GeV for B(H±±→ℓ±ℓ±)=10% and any combination of partial branching ratios
