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 ...

Minimum rank of graphs that allow loops [PDF]
, 2008 The traditional "minimum rank problem" for simple graphs associates a set of symmetric matrices, the zero-nonzero pattern of whose off-diagonal entries are described by the graph, over a particular field and asks us to find the minimum among the ranks of

The Minimum Rank of Universal Adjacency Matrices [PDF]
, 2012 In this paper we introduce a new parameter for a graph called the minimum universal rank. This parameter is similar to the minimum rank of a graph. For a graph G the minimum universal rank of G is the minimum rank over all matrices of the form U(α,β,γ,δ)=

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Pediatric thromboembolism is increasingly encountered in critical care. Systemic thrombolysis with tissue plasminogen activator (tPA) facilitates vessel or valve patency, yet pediatric‐specific protocols remain undefined, and safety concerns persist. Objective To evaluate the efficacy and safety of a tailored, prolonged systemic tPA

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.

Global Efforts to Reduce Paediatric Cancer Care Disparities in Radiotherapy: A Decade Change
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background We present an update on the status, needs and challenges faced by paediatric imaging and radiotherapy (RT) programmes globally after a previous survey conducted by the International Atomic Energy Agency (IAEA) 10 years prior. Methods We developed and distributed a 121‐question survey to radiation oncologists, medical physicists and ...
