Base-Controlled Regiospecific Mono-Benzylation/Allylation and Diallylation of 4-Aryl-5-indolyl-1,2,4-triazole-3-thione : Thio-Aza Allyl Rearrangement
(MDPI AG, 2023)
The regiospecific S-benzylation/allylation of two 4-aryl-5-indolyl-1,2,4-triazole-3-thione precursors was carried out using Et3N as a base. Allyl group migration from exocyclic sulfur to the triazole nitrogen (N3) was ...
Base-promoted direct amidation of esters : beyond the current scope and practical applications
(Royal Society of Chemistry (RSC), 2022)
The base-promoted direct amidation of unactivated esters is among the most useful reactions for amide bond formation in contemporary organic chemistry. The intensive research in this area has led to the development of a ...
Bateman gradients from first principles
(Nature Publishing Group, 2022)
In 1948, Angus Bateman presented experiments and concepts that remain influential and debated in sexual selection. The Bateman gradient relates reproductive success to mate number, and Bateman presented this as the cause ...
Baum-Katz’s Type Theorems for Pairwise Independent Random Elements in Certain Metric Spaces
(National Center for Scientific Research, 2020)
In this study, some Baum-Katz’s type theorems for pairwise independent random elements are extended to a metric space endowed with a convex combination operation. Our results are considered in the cases of identically ...
Bayesian estimation of the specific shear and bulk viscosity of the quark-gluon plasma with additional flow harmonic observables
(American Physical Society, 2021)
The transport properties of the strongly coupled quark-gluon plasma created in ultrarelativistic heavy-ion
collisions are extracted by Bayesian parameter estimate methods with the latest collision beam energy data from
the ...
Bayesian inference of the fluctuating proton shape
(Elsevier BV, 2022)
Using Bayesian inference, we determine probabilistic constraints on the parameters describing the fluctuating structure of protons at high energy. We employ the color glass condensate framework supplemented with a model ...
Bayesian Modeling of Sequential Discoveries
(Taylor & Francis, 2022)
We aim at modelling the appearance of distinct tags in a sequence of labelled objects. Common examples of this type of data include words in a corpus or distinct species in a sample. These sequential discoveries are often ...
Bayesian models for data missing not at random in health examination surveys
(Sage Publications India Pvt. Ltd., 2018)
In epidemiological surveys, data missing not at random (MNAR) due to survey nonresponse may potentially lead to a bias in the risk factor estimates. We propose an approach based on Bayesian data augmentation and survival ...
Bayesian semiparametric long memory models for discretized event data
(Institute of Mathematical Statistics, 2022)
We introduce a new class of semiparametric latent variable models for long memory discretized event data. The proposed methodology is motivated by a study of bird vocalizations in the Amazon rain forest; the timings of ...
Bayesian subcohort selection for longitudinal covariate measurements in follow‐up studies
(Wiley-Blackwell, 2022)
We propose an approach for the planning of longitudinal covariate measurements in follow-up studies where covariates are time-varying. We assume that the entire cohort cannot be selected for longitudinal measurements due ...
