Influence of Non-uniform Parameter of Bolt Joint on Complexity of Frequency Characteristics of Cylindrical Shell

open access: yesChinese Journal of Mechanical Engineering, 2023
Bolt connection is one of the main fixing methods of cylindrical shell structures. A typical bolted connection model is considered as a tuned system. However, in the actual working conditions, due to the manufacturing error, installation error and uneven

The research on Bayesian inference for geophysical inversion

open access: yes地球与行星物理论评, 2022
Based on statistical theory, the Bayesian inversion method adopts the posterior probability distribution to evaluate the model parameters under the constraints of prior information and observation data.

Theory of Statistical Fluctuations in Neutron Distributions [PDF]

open access: yesJournal of Nuclear Science and Technology, 1965
Statistical fluctuations in neutron and precursor distributions in a reactor are investigated in a continuous phase space. The theory is constructed on the basis of Ramakrishnan's product density and of the concept of “detectrons”. The basic equations for the product densities of degree 2 are derived and solved.

Size structure of earthworms populations and the theory of neutrality

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2007
The paper points that neutrality theory allows to describe a distribution of earthworms’ body weight classes in the population. The statistical parameters can be interpreted in terms of the population ecology. The dynamics of parameters distribution over

Extended Matrix Variate Hypergeometric Functions and Matrix Variate Distributions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2015
Hypergeometric functions of matrix arguments occur frequently in multivariate statistical analysis. In this paper, we define and study extended forms of Gauss and confluent hypergeometric functions of matrix arguments and show that they occur naturally ...

A New Approach to Bivariate Transmutation: Construction of Continuous Bivariate Distribution Under Negative Dependency

open access: yesCumhuriyet Science Journal, 2020
In this study, a new approach to transmutation theory is developed by using negative dependency basement. Once choosing a distribution that has negative dependency with the same marginal, a new bivariate distribution is derived.

Zero-bias anomaly and role of electronic correlations in a disordered metal film

open access: yesNew Journal of Physics, 2020
Localization and electron correlation play significant roles in understanding the electronic states of low-dimensional systems. We carried out the tunneling spectroscopy measurements on a crystalline nano-sized island and a disordered two-dimensional ...

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.
