Background & Objective: Oral health problems of chronic renal failure patients can compromise systemic health. The purpose of this study was to investigate the dental and periodontal status of patients on regular hemodialysis (HD) maintenance therapy and the effect of duration of HD on oral health. Methods & Materials: In this historical cohort study 65 HD patients and 65 healthy people we...
BACKGROUND The diagnostic power of the transferrin receptor-ferritin (TfR-F) index for identification of iron responsiveness in long-term hemodialysis (HD) patients compared with the routine markers recommended by the current US and European guidelines was appraised. METHODS Initially, 121 long-term HD patients with a serum ferritin level less than 800 microg/L and on recombinant erythropoiet...
The forgotten topological index or F-index of a graph is defined as the sum of cubes of the degree of all the vertices of the graph. In this paper we study the F-index of four operations related to the lexicographic product on graphs which were introduced by Sarala et al. [D. Sarala, H. Deng, S.K. Ayyaswamya and S. Balachandrana, The Zagreb indices of graphs based on four new operations related...
And recall that the INDEX model has the lower bound for deterministic communication complexity: CCδ(INDEX) ≥ I(M ;X|R) ≥ n(1−H(δ)), where R is the shared common random string. We need a lower bound when conditioning on R for our earlier Gap-Hamming lower bound, which was a reduction from INDEX using the shared common random string R. Definition. Given (X,Y ) ∼ μ, the μ-distributional communicat...
Maňuch and Stacho [7] introduced the problem of designing f -tolerant routings in optical networks, i.e., routings which still satisfy the given requests even if f failures occur in the network. In this paper, we provide f -tolerant routings in complete and complete balanced bipartite optical networks, optimal according to two parameters: the arc-forwarding index and the optical index. These co...
Abstract The molecular descriptors are a useful tool in the spectral graph, chemistry and several fields of mathematics. edge F-index is proposed for fuzzy graphs (FGs) here. Bounds this index calculated FGs. FG has been investigated given set vertices as having maximum F-index. Some relations with second Zagreb hyper-Zagreb established. For an isomorphic FGs, it shown that value same. some ope...
