Double Beta Decay: A Shell Model Approach

Physics, 2022
Studies of weak interaction in nuclei are important tools for testing different aspects of the fundamental symmetries of the Standard Model. Neutrinoless double beta decay offers an unique venue of investigating the possibility that neutrinos are ...

A Beta-splitting model for evolutionary trees [PDF]

Royal Society Open Science, 2016
In this article, we construct a generalization of the Blum–François Beta-splitting model for evolutionary trees, which was itself inspired by Aldous' Beta-splitting model on cladograms.

Maximum lilkelihood estimation in the $\beta$-model

Annals of Statistics, 2013
We study maximum likelihood estimation for the statistical model for undirected random graphs, known as the $\beta$-model, in which the degree sequences are minimal sufficient statistics. We derive necessary and sufficient conditions, based on the polytope of degree sequences, for the existence of the maximum likelihood estimator (MLE) of the model ...

Beta testing the monkey model [PDF]

Nature Immunology, 2021
Corbett et al. use the rhesus macaque model to evaluate the ability of the mRNA-1273 (Moderna) COVID-19 vaccine to protect against challenge with the antibody-evading Beta variant of SARS-CoV-2. Their key finding is that the vaccine prevents severe lung pathology, principally because it is able to induce a strong enough antibody resistance to overcome ...

THE REACTIVE BETA MODEL [PDF]

Journal of Financial Research, 2019
Abstract We present a reactive beta model that accounts for the leverage effect and beta elasticity. For this purpose, we derive a correlation metric for the leverage effect to identify the relation between the market beta and volatility changes.

Matrix models for beta ensembles [PDF]

Journal of Mathematical Physics, 2002
This paper constructs tridiagonal random matrix models for general (β>0) β-Hermite (Gaussian) and β-Laguerre (Wishart) ensembles. These generalize the well-known Gaussian and Wishart models for β=1,2,4. Furthermore, in the cases of the β-Laguerre ensembles, we eliminate the exponent quantization present in the previously known models. We further
