Research on Improving the Prediction Accuracy of Build-up Rate Based on Kriging Method

open access: yesShiyou jixie, 2023
The traditional build-up rate prediction methods in the drilling industry have some shortcomings,such as low prediction accuracy using geometric method and high computational complexity using mechanical method,which indirectly increase drilling costs ...

Absolute quantitation of microbes using 16S rRNA gene metabarcoding: A rapid normalization of relative abundances by quantitative PCR targeting a 16S rRNA gene spike‐in standard

open access: yesMicrobiologyOpen, 2020
Metabarcoding of the 16S rRNA gene is commonly used to characterize microbial communities, by estimating the relative abundance of microbes. Here, we present a method to retrieve the concentrations of the 16S rRNA gene per gram of any environmental ...

Normal Extensions

open access: yesFormalized Mathematics, 2023
Summary In this article we continue the formalization of field theory in Mizar [1], [2], [4], [3]. We introduce normal extensions: an (algebraic) extension E of F is normal if every polynomial of F

The curse of normalization [PDF]

open access: yesComparative and Functional Genomics, 2002
AbstractDespite its enormous promise to further our understanding of cellular processes involved in the regulation of gene expression, microarray technology generates data for which statistical pre‐processing has become a necessity before any interpretation of data can begin.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Assessing tree species diversity in forest ecosystems: A new approach

open access: yesFrontiers in Ecology and Evolution, 2022
The significance of biodiversity research is to understand the structure and function of the community, and then to protect and monitor the community. The metric of biodiversity is the base of biodiversity conservation.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Selection and Evaluation of Reference Genes for miRNA Expression Analysis in Bemisia tabaci Under Insecticide Tolerance

open access: yesFrontiers in Genetics, 2022
A growing number of studies have focused on the microRNA (miRNA) expression in Bemisia tabaci, one devastating agricultural insect pest of the tropical and subtropical areas for which the primary means of control are insecticides. In studying the genetic

Bicervical normal uterus with normal vagina

open access: yesAnnals of Medical and Health Sciences Research, 2014
This is a report of the form of uterine anomaly involving a dual cervical canal in a side-by-side disposition with normal uterine cavity and normal vagina. It portrays a form of congenital uterine anomaly not explicable by the existing classical theory of mullerian anomalies.
