The Correlation Between Body Fat Percentage and Peak Expiratory Flow in Children Aged 10-12 Years at SD Negeri 8 Dauh Puri [PDF]

open access: yes, 2019
Background: The accumulation of fat decreases lung function. Peak expiratory flow is an indicator for assessing pulmonary function and can be used to identify the narrowing or obstruction of the airway. This study aimed to examine the correlation between

The observed radio/gamma-ray emission correlation for blazars with the Fermi-LAT and the RATAN-600 data [PDF]

open access: yes, 2015
We study the correlation between gamma-ray and radio band radiation for 123 blazars, using the Fermi-LAT first source catalog (1FGL) and the RATAN-600 data obtained at the same period of time (within a few months).

Zero Pearson coefficient for strongly correlated growing trees [PDF]

open access: yesPhysical Review E, 2010
We obtained Pearson's coefficient of strongly correlated recursive networks growing by preferential attachment of every new vertex by $m$ edges. We found that the Pearson coefficient is exactly zero in the infinite network limit for the recursive trees ($m=1$).
