Experimental work was conducted at four study sites: in Kazakhstan, Abdrakhmanov Bolat Dauletbekovich SP (Akmola region) and Alimzhanov TS farm (Almaty region); in the Republic of Tuva, Oyun SP of Kyzyl district (forest-steppe population) and SPK Breeding Farm … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 14 Jan 2026 · 2,373 accessesView PDFCite
Research ArticleOpen accessIn the abstractBayesian Network Inference in Binary Logistic Regression: A Case Study of Salmonella sp Bacterial Contamination on Vannamei ShrimpPratnya Paramitha Oktaviana, Kartika FithriasariRecently binary logistic regression has been used to identify four factors or predictor variables that supposedly influence the response variable, which is testing result of Salmonella sp bacterial contamination on vannamei shrimp. Binary logistic regression analysis results that there are two predictor variables which is significantly affect the testing result of Salmonella sp bacterial contamination on vannamei shrimp, those are … …Journal of Mathematics and Statistics, Vol. 13, Issue 4 · 22 Dec 2017 · 7,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Time of Flooding Occurrence is Critical for Yield Production in Rice and Vary in a Genotype-Dependent MannerJenjira Mongon, Arom Jantasorn, Prateep Oupkaew et al.Flash floods occur in rainfed lowland and flood-prone areas and have a profound incidence on crop yield, which is tightly linked to worldwide food insecurity. The most flooding-threatened crop is rice. Under this condition, rice undergoes anoxic and post-anoxic shock that affects its growth, development capacity and ultimately causes an important grain yield loss. Therefore, the introduction of submergence-tolerant varieties … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 3 Jun 2017 · 8,093 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and Characterization of Diacylglycerol Acyltransferase in Oleaginous Yeast Rhodosporidium toruloidesZhen Wang, Huaiyuan Zhang, Lina Zhao, Yuanda SongDiacylglycerol acyltransferase (DGAT), which catalyzes TAG formation from DAG and acyl-CoA, has been considered to play a vital role in TAG accumulation in oleaginous microorganisms. The genome of oleaginous yeast Rhodosporidium toruloides contains two putative DGAT genes, RtDGATa and RtDGATb, which shared little conserved amino acid coding sequence with each other. Phylogeny tree analysis showed that RtDGATa belonged to DGAT1 … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 17 Oct 2016 · 7,387 accessesView PDFCite

Research ArticleOpen accessIn the abstractHEURISTIC DISCRETIZATION METHOD FOR BAYESIAN NETWORKSMariana D.C. Lima, Silvia M. Nassar, Pedro Ivo R.B.G. Rodrigues et al.Bayesian Network (BN) is a classification technique widely used in Artificial Intelligence. Its structure is a Direct Acyclic Graph (DAG) used to model the association of categorical variables. However, in cases where the variables are numerical, a previous discretization is necessary. Discretization methods are usually based on a statistical approach using the data distribution, such as division by quartiles. In … …Journal of Computer Science, Vol. 10, Issue 5 · 18 Jan 2014 · 7,054 accessesView PDFCite
