Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

On the enumeration of polyhedra
Discrete Mathematics, 1982 AbstractAn algorithm for the enumeration of all combinatorial types of three-dimensional polyhedra is described and the respective numbers of polyhedra with f faces, 4⩽f⩽11, are listed.

Weakly prudent self-avoiding bridges [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 We define and enumerate a new class of self-avoiding walks on the square lattice, which we call weakly prudent bridges. Their definition is inspired by two previously-considered classes of self-avoiding walks, and can be viewed as a combination of those ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing

Enumeration of minimal 3D polyominoes inscribed in a rectangular prism [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 We consider the family of 3D minimal polyominoes inscribed in a rectanglar prism. These objects are polyominos and so they are connected sets of unitary cubic cells inscribed in a given rectangular prism of size $b\times k \times h$ and of minimal volume

Enumeration of generalized polyominoes [PDF]
, 2006 As a generalization of polyominoes we consider edge-to-edge connected nonoverlapping unions of regular $k$-gons. For $n\le 4$ we determine formulas for the number $a_k(n)$ of generalized polyominoes consisting of $n$ regular $k$-gons.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

Generating functions of bipartite maps on orientable surfaces (extended abstract) [PDF]
Discrete Mathematics & Theoretical Computer Science, 2015 We compute, for each genus $g$ ≥ 0, the generating function $L$$g$ ≡ $L$$g$($t$;$p$1,$p$2,...) of (labelled) bipartite maps on the orientable surface of genus $g$, with control on all face degrees. We exhibit an explicit change of variables such
