Independence number in graphs and its upper bounds [PDF]

open access: yesJournal of Mahani Mathematical Research
‎In this paper, we use the double counting method to find some upper bounds for the independence number of a simple graph in terms of its order, size and  maximum degree.   Moreover,  we determine extremal graphs attaining equality in upper bounds.

Two sufficient conditions for fractional k-deleted graphs

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
Let G be a graph, and k a positive integer. A fractional k-factor is a way of assigning weights to the edges of a graph G (with all weights between 0 and 1) such that for each vertex the sum of the weights of the edges incident with that vertex is k.

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about

On the Ramsey-Tur\'an number with small $s$-independence number [PDF]

open access: yes, 2015
Let $s$ be an integer, $f=f(n)$ a function, and $H$ a graph. Define the Ramsey-Tur\'an number $RT_s(n,H, f)$ as the maximum number of edges in an $H$-free graph $G$ of order $n$ with $\alpha_s(G) < f$, where $\alpha_s(G)$ is the maximum number of ...

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...

Ideal Independence, Free Sequences, and the Ultrafilter Number [PDF]

open access: yes, 2013
We make use of a forcing technique for extending Boolean algebras. The same type of forcing was employed in [BK81], [Kos99], and elsewhere. Using and modifying a lemma of Koszmider, and using CH, we obtain an atomless BA, A such that f(A) = smm(A) < u(A),

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

Incidence and Outcome of Infants With Cancer in Canada: A Report From Cancer in Young People in Canada Database

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Infants with cancer are rare and face unique challenges. Our study aims to describe the incidence of infantile cancers in Canada and to compare treatment‐related mortality (TRM) and their outcomes with those of older children. Methods We conducted a retrospective cohort study using the Cancer in Young People in Canada database ...

RT‐PCR–Based Detection of Bone Marrow Involvement in Ewing Sarcoma: Diagnostic Validity and Prognostic Relevance

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background In Ewing sarcoma (EwS), metastases, including those to bone marrow (BM), are the main factors influencing prognosis. Although reverse transcription polymerase chain reaction (RT‐PCR) offers greater sensitivity, the current EWING protocol defines BM metastases solely using light microscopic detection.

A note on subspace sum graph of vector spaces

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
For a finite dimensional vector space over a field the subspace sum graph of denoted by is defined to be a simple undirected graph with vertex set as the set of all non-trivial proper subspace of and, for any two distinct vertices V1 and V2 are adjacent ...
