On the Weak Reconstruction of Strong Product Graphs
Electronic Notes in Discrete Mathematics, 2003 We prove that any nontrivial connected strong product graph can be uniquely reconstructed from each of its one vertex deleted subgraphs.

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...

Sharp Upper Bounds for Generalized Edge-Connectivity of Product Graphs
Discussiones Mathematicae Graph Theory, 2016 The generalized k-connectivity κk(G) of a graph G was introduced by Hager in 1985. As a natural counterpart of this concept, Li et al. in 2011 introduced the concept of generalized k-edge-connectivity which is defined as λk(G) = min{λ(S) : S ⊆ V (G) and |

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Adolescents with haematological malignancies face significant emotional and relational challenges, often accompanied by difficulties in communicating their needs within the healthcare context. To address these issues, a narrative‐based psycho‐educational intervention based on the creation and prescription of Ironic Medications was ...

2-Tone Colorings in Graph Products
Discussiones Mathematicae Graph Theory, 2015 A variation of graph coloring known as a t-tone k-coloring assigns a set of t colors to each vertex of a graph from the set {1, . . . , k}, where the sets of colors assigned to any two vertices distance d apart share fewer than d colors in common.

NZ‐flows in strong products of graphs
Journal of Graph Theory, 2010 AbstractWe prove that the strong product G1⊠ G2 of G1 and G2 is ℤ3‐flow contractible if and only if G1⊠ G2 is not T⊠ K2, where T is a tree (we call T⊠ K2 a K4‐tree). It follows that G1⊠ G2 admits an NZ 3 ‐flow unless G1⊠ G2 is a K4 ‐tree. We also give a constructive proof that yields a polynomial algorithm whose output is an NZ 3‐flow if G1⊠ G2 is not ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Objectives The association between exposure to dinutuximab beta (DB) and event‐free survival (EFS) or overall survival (OS) of neuroblastoma patients was assessed using data collected during three clinical trials (five cohorts). Methods A systematic review (March 2026) was conducted to identify relevant studies (prospective; registered DB ...

Fast recognition of direct and strong products
Ars Mathematica Contemporanea, 2014 Summary: This note describes fast algorithms for computing the prime factors of connected, nonbipartite graphs with respect to the direct product, and of connected graphs with respect to the strong product. The complexities are \(O(m \min(n^{2} {\Delta}^{3}))\) for the direct product, and \(O(m\,a(G) \Delta)\) for the strong, where \(n\) is the order ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Medication nonadherence during the first 100 days after pediatric hematopoietic stem cell transplantation (HSCT) and during oncology treatment increases risk for complications. BMT4me is a caregiver‐facing mobile health (mHealth) application providing medication reminders, symptom tracking, and note‐taking features to support ...
