On the Symmetry of the Distribution of $k$-Crossings and $k$-Nestings in Graphs [PDF]

The Electronic Journal of Combinatorics, 2006
This note contains two results on the distribution of $k$-crossings and $k$-nestings in graphs. On the positive side, we exhibit a class of graphs for which there are as many $k$-noncrossing $2$-nonnesting graphs as $k$-nonnesting $2$-noncrossing graphs. This class consists of the graphs on $[n]$ where each vertex $x$ is joined to at most one vertex $y$

Research on Distribution Network Security Analysis Based on K(N-1+k) Criterion and Rank Preference Optimal Ordering

Journal of Applied Mathematics, 2014
The objective of security analysis is to find the weak link of distribution network. The K(N-1+k) criterion based on the characteristics of distribution network was proposed for distribution network security analysis. According to the K(N-1+k) criterion,

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

On Generalized Upper(k)Record Values From Weibull Distribution

Statistica, 2015
In this paper we study the generalized upper(k)record values arising from Weibull distribution. Expressions for the moments and product moments of those generalized upper(k)record values  are derived.

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.
