GENERALIZED QUADRATIC MAPPINGS IN 2d VARIABLES [PDF]

Korean Journal of Mathematics, 2011
Summary: Let \(X, Y\) be vector spaces. It is shown that if an even mapping \(f:X \rightarrow Y\) satisfies \(f(0)=0\), and \[ \begin{aligned} & 2(_{2d-2} C_{d-1} -_{2d-2} C_d) f \left(\sum_{j=1}^{2d} x_j \right) + \displaystyle\sum_{i(j) = 0,1, \sum_{j=1}^{2d} i(j)=d} f \left(\sum_{j=1}^{2d} (-1)^{ i(j)} x_j \right) \\ & = 2(_{2d-1} C_d +_{2d-2} C_{d ...

Discordance Between Patient and Physician Global Assessments in Early Systemic Sclerosis

Arthritis Care &Research, EarlyView.
Objective This study aims to identify factors associated with patient global assessment (PtGA) and physician global assessment (PhGA) and discordance between them in systemic sclerosis (SSc). Methods Data from adults with early SSc (<5 years) from the Collaborative National Quality and Efficacy Registry were included.

Upper bounds on the genus of hyperelliptic Albanese fibrations

Forum of Mathematics, Sigma
Let S be a minimal irregular surface of general type, whose Albanese map induces a hyperelliptic fibration $f:\,S \to B$ of genus g. We prove a quadratic upper bound on the genus g (i.e., $g\leq h\big (\chi (\mathcal {O}_S)\big )$ , where h ...

Transmuted Rayleigh Distribution

Austrian Journal of Statistics, 2016
In this article, we generalize the Rayleigh distribution using the quadratic rank transmutation map studied by Shaw et al. (2009) to develop a transmuted Rayleigh distribution.

Discordance Between Systemic Lupus Erythematosus Disease Activity Index Domain Weights and Their Association With Organ Damage Accrual

Arthritis Care &Research, EarlyView.
Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1–8) assigned to each domain.

Bilinear Minimax Optimal Control Problems for a von Kárman System with Long Memory

Journal of Function Spaces, 2020
In the present article, we consider a von Kárman equation with long memory. The goal is to study a quadratic cost minimax optimal control problems for the control system governed by the equation. First, we show that the solution map is continuous under a

Better Process Mapping and Sparse Quadratic Assignment [PDF]

ACM Journal of Experimental Algorithmics, 2020
Communication and topology-aware process mapping is a powerful approach to reduce communication time in parallel applications with known communication patterns on large, distributed memory systems. We address the problem as a quadratic assignment problem (QAP) and present algorithms to construct initial mappings of processes to processors and fast ...
