On the Beta-Number of Forests with Isomorphic Components [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2018
The beta-number, β (G), of a graph G is defined to be either the smallest positive integer n for which there exists an injective function f : V (G) → {0, 1, . . .

On the beta-number of linear forests with an even number of components [PDF]

open access: goldAKCE International Journal of Graphs and Combinatorics, 2018
The beta-number of a graph is the smallest positive integer for which there exists an injective function such that each is labeled and the resulting set of edge labels is for some positive integer . The beta-number of is , otherwise.

On the strong beta-number of galaxies with three and four components [PDF]

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
The beta-number of a graph is the smallest positive integer for which there exists an injective function such that each is labeled and the resulting set of edge labels is for some positive integer . The beta-number of is if there exists no such integer .

Formulated New Identities of Fibonacci Numbers with James Abacus Diagram

open access: yesJournal of Applied Science and Engineering, 2021
This paper focuses on developing a strategy to represent a new Fibonacci identity using James abacus. The idea of a Graphical chain with respect to the beta numbers and abacus was established to count the number of ways to tile a James diagram chain ...

Glucose regulates rat beta cell number through age-dependent effects on beta cell survival and proliferation. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: Glucose effects on beta cell survival and DNA-synthesis suggest a role as regulator of beta cell mass but data on beta cell numbers are lacking.

The association between beta-blocker use and chronic obstructive pulmonary disease risk, severity, and exacerbation

open access: yesMedical Journal of Babylon, 2021
Background: There is controversy about the role of beta-blockers in the number of acute exacerbations in patients with chronic obstructive pulmonary disease (COPD).

Beta cell count instead of beta cell mass to assess and localize growth in beta cell population following pancreatic duct ligation in mice. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Pancreatic-tail duct ligation (PDL) in adult rodents has been reported to induce beta cell generation and increase beta cell mass but increases in beta cell number have not been demonstrated.

Survivin is required for beta-cell mass expansion in the pancreatic duct-ligated mouse model. [PDF]

open access: yesPLoS ONE, 2012
AIMS/HYPOTHESIS:Pancreatic beta-cell mass expands through adulthood under certain conditions. The related molecular mechanisms are elusive. This study was designed to determine whether surviving (also known as Birc5), which is transiently expressed ...
