Optimized Green Synthesis of Silver Nanoparticles Using Ocimum gratissimum Extract With Antibacterial and Antibiofilm Activity Against Multidrug‐Resistant Bacteria

ChemistrySelect, Volume 11, Issue 19, 20 May 2026.
ABSTRACT While several studies have explored the green production of silver nanoparticles (AgNPs), only a limited number have specifically investigated their antibacterial properties when synthesized using Ocimum gratissimum (OG) extracts as both a reducing and stabilizing agent.

Uniform confidence bands for functions estimated nonparametrically with instrumental variables [PDF]

This paper is concerned with developing uniform confidence bands for functions estimated nonparametrically with instrumental variables. We show that a sieve nonparametric instrumental variables estimator is pointwise asymptotically normally distributed ...

Categorical variables in DEA. [PDF]

If a DEA model has a mix of categorical and continuous variables a standard LP formulation can still be used by entering all combinations of categorical and continuous variables as different types of inputs and/or outputs.

On Independence Nuetrosophic Random Variables

, 2021
In this article we study independence neutrosophic random variables and conditioned expectation, we prove that conditional variance is equal to neutrosophic conditional variance.
Carlos Granados In this article we study independence neutrosophic random variables and conditioned expectation, we prove that conditional variance is equal to neutrosophic conditional variance. These notions are important for neutrosophic probability due to neutrosophic random variables, neutrosophic central limit theorem and neutrosophic laws of large numbers can be studied., Jos´e Sanabria   +1 more
