Propensity-score matching is a popular analytic method to estimate the effects of treatments when using observational data. Matching on the propensity score typically requires a pool of potential controls that is larger than the number of treated or exposed subjects. The most common approach to matching on the propensity score is matching without…[Read more]

Complex architectures like 3D gold dendritic nanostructures were synthesized by an in situ templated growth method using a thin film of a block copolymer [polystyrene-b-poly(4-vinylpyridine)] deposited onto silicon substrates. The overall study has demonstrated the strong link between the morphology, size, and distribution of the structures and…[Read more]

Our model provides an explicit impression of the complex nexus of CHES amid the current crisis. The proposed conceptual model could help in understanding the complex nexus by identifying the route of short-term impacts of COVID-19 measures and thus may aid in identifying priority areas for discussion and planning in similar crises as well.Nickel…[Read more]

Antimicrobial resistance is a serious public health threat worldwide today. Escherichia coli is known to resist low doses of antibiotics in the presence of sodium salicylate and related compounds by mounting non-heritable transient phenotypic antibiotic resistance (PAR). In the present study, we demonstrate that Bgl+ bacterial strains harboring a…[Read more]
