Some Rank Records for Elliptic Curves with Prescribed Torsion Over Quadratic Fields
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 In this paper we construct elliptic curves over quadratic fields with prescribed torsion group and record rank. We do this using theoretical arguments and keeping lengthy computations to a minimum.

A novel three-stage distance-based consensus ranking method
Journal of Industrial Engineering International, 2018 In this study, we propose a three-stage weighted sum method for identifying the group ranks of alternatives. In the first stage, a rank matrix, similar to the cross-efficiency matrix, is obtained by computing the individual rank position of each ...

On Haber's Minimum Term Rank Formula
European Journal of Combinatorics, 1981 A simple proof is given of a simplification of Haber's formula for the minimum term rank of matrices of 0's and 1's with a specified row and column sum vector.

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 ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

EURASIP Journal on Advances in Signal Processing, 2008 Adaptive reduced-rank (RR) multistage matrix Wiener filtering (MMWF) techniques, based on the minimum mean-square error (MMSE) criterion, are proposed for direct-sequence (DS) ultra-wideband (UWB) communication systems.

Minimum rank with zero diagonal
The Electronic Journal of Linear Algebra, 2014 Associated with a simple graph G is a family of real, symmetric zero diagonal matrices with the same nonzero pattern as the adjacency matrix of G. The minimum of the ranks of the matrices in this family is denoted mr0(G). We characterize all connected graphs G with extreme minimum zero-diagonal rank: a connected graph G has mr0(G) 3 if and only if it

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...
