Independence number of generalized Petersen graphs
, 2010 Determining the size of a maximum independent set of a graph $G$, denoted by $ (G)$, is an NP-hard problem. Therefore, many attempts are made to find upper and lower bounds, or exact values of $ (G)$ for special classes of graphs. This paper is aimed toward studying this problem for the class of generalized Petersen graphs.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Osteosarcoma is a radioresistant tumor that may benefit from stereotactic body radiation therapy (SBRT) for locoregional control in metastatic/recurrent disease. We report institutional practice patterns, outcomes, toxicity, and failures in osteosarcoma patients treated with SBRT.

On the Total Graph of Mycielski Graphs, Central Graphs and Their Covering Numbers
Discussiones Mathematicae Graph Theory, 2013 The technique of counting cliques in networks is a natural problem. In this paper, we develop certain results on counting of triangles for the total graph of the Mycielski graph or central graph of star as well as completegraph families.

Two Degree Distance Based Topological Indices of Chemical Trees
IEEE Access, 2019 Let G = (VG, EG) be a simple and connected graph. The eccentric connectivity index of G is represented as ξc(G) = Σx∈VG degG(x)ecG(x), where degG(x) and ecG(x) represent the degree and the eccentricity of x, respectively.

New Results Relating Independence and Matchings
Discussiones Mathematicae Graph Theory, 2022 In this paper we study relationships between the matching number, written µ(G), and the independence number, written α(G).

Pediatric Blood &Cancer, EarlyView.ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

$ Z_{3} $-connectivity of graphs with independence number at most 3
AIMS Mathematics, 2023 It was conjectured by Jaeger et al. that all 5-edge-connected graphs are $ Z_3 $-connected. In this paper, we confirm this conjecture for all 5-edge-connected graphs with independence number at most 3.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Cyclophosphamide (CY) is associated with potentially fatal cardiotoxicity, yet no electrocardiographic indices have been established for early detection of CY‐induced cardiomyopathy. This study aimed to determine whether corrected QT interval (QTc) prolongation can predict early onset of CY‐related cardiac dysfunction in pediatric ...

On Generalized Sierpiński Graphs
Discussiones Mathematicae Graph Theory, 2017 In this paper we obtain closed formulae for several parameters of generalized Sierpiński graphs S(G, t) in terms of parameters of the base graph G. In particular, we focus on the chromatic, vertex cover, clique and domination numbers.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...
