The study encompasses various analytical techniques, including descriptive statistics, Cronbach’s Alpha, Exploratory Factor Analysis (EFA), multivariate regression models, and hypothesis testing through SPSS software. The findings reveal that six key factors, namely leadership, digital business strategy, employee capabilities, technology infrastructure, organizational culture, and external market pressures, exert significant influence on digital transformation in these enterprises.

The impact of climate change on sea level has attracted much attention from scientists worldwide. The analysis of sea-level change at global and regional scales is based on altimetry and/or tide gauge data. The main objective’s study relied on statistical tests to highlight the significant long-term changes in sea level in Ha Long coastal area through the 47 years (1974–2020) historical tide gauge record of the Bai Chay station.

Selecting chromosome substitution strains (CSSs, also called consomic strains/lines) used in the search for quantitative trait loci (QTLs) consistently requires the identification of the respective phenotypic trait of interest and is simply based on a significant difference between a consomic and host strain. However, statistical significance as represented by P values does not necessarily predicate practical importance.

We show that epigenome- and transcriptome-wide association studies (EWAS and TWAS) are prone to significant inflation and bias of test statistics, an unrecognized phenomenon introducing spurious findings if left unaddressed. Neither GWAS-based methodology nor state-of-the-art confounder adjustment methods completely remove bias and inflation.

This work was planned to research the effects of lipopolysaccharide (LPS) and/or vitamin E (VE) and sodium selenite (SS), which have antioxidant properties, administered to the liver tissue of male rats. For this purpose, histopathology, immunohistochemistry, antioxidant capacity, terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling assay, liver function, and DNA structure tests were performed. The lipid profile was also evaluated in this study. Rats that were administered LPS were treated with VE and/or SS.

The PTP stratification models were calculated according to the recommendations of the European Society of Cardiology (ESC) 2013 and 2019. Coronary angiography was enrolled for the diagnosis, Quantitative coronary analyzed (QCA) - based stenosis assessment was used with a cut-off of ≥ 50% diameter reduction for significant lesions of coronary artery and SYNTAX score were calculated.Diagnostic accuracy was calculated by usingsensitivity, specificitywhich were analyzed by using statistical software SPSS version 20.0.

Poly(ethylene glycol) bis(methylimidazolium) di[bis(trifluoromethylsulfonyl)imide] was synthesized as an ionic liquid and impregnated onto chitosan. The removal of uranium(VI) ions from aqueous solution was investigated with batch sorption tests using ionic liquid impregnated chitosan. Response surface methodology based on 3 level Box– Behnken design was applied to analyze the effect of initial pH (4–6), initial concentration (20–60 mg L −1 ), contact time (15–105 min), and temperature (30–50°C) on the uptake capacity of uranium(VI).

Transposable elements (TEs) are interspersed DNA sequences that can move or copy to new positions within a genome. TEs are believed to promote speciation and their activities play a significant role in human disease. In the human genome, the 22 AluY and 6 AluS TE subfamilies have been the most recently active, and their transposition has been implicated in many inherited human diseases and in various forms of cancer.

Selection of an appropriate statistical significance threshold in genome-wide association studies is critical to differentiate true positives from false positives and false negatives. Different multiple testing comparison methods have been developed to determine the significance threshold; however, these methods may be overly conservative and may lead to an increase in false negatives.
