A class of quasi-Newton generalized Steffensen methods on Banach spaces

, 2002
We consider a class of generalized Steffensen iterations procedure for solving nonlinear equations on Banach spaces without any derivative. We establish the convergence under the Kantarovich–Ostrowski's conditions.

Majorization and the degree sequence of trees

Iberoamerican Journal of Science Measurement and Communication
Objective. This study investigated the relation between the degree sequences of trees and the majorization order. Design/Methodology/Approach. The majorization technique was employed in accordance with the tenets of Muirhead’s theorem. Results. In this study, we proved a theorem that provides a necessary and sufficient condition for degree sequences of

Deep Sequencing of FLT3‐ITD Enables Response Evaluation and Post‐Treatment Monitoring in Childhood AML: An Exploratory Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...

The Genes for Major Psychosis Aberrant Sequence or Regulation? [PDF]

Neuropsychopharmacology, 2000
A number of recent clinical and molecular observations in major psychosis indicate that epigenetic factors may be operational in the origin of major mental illness. This article further develops the idea that epigenetic factors may play an etiopathogenic role in schizophrenia and bipolar affective disorder.

Prognosis of Long‐Term Continuous Renal Replacement Therapy and the Impact of Combined Continuous Intravenous Sodium Infusion Therapy

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.

A unified framework for low autocorrelation sequence design via majorization-minimization

, 2017
In this paper, we consider the low autocorrelation sequence design problem. We optimize a unified metric over a general constraint set. The unified metric includes the integrated sidelobe level (ISL) and the peak sidelobe level (PSL) as special cases ...

Expanding the applicability of Newton-Tikhonov method for ill-posed equations

Journal of Numerical Analysis and Approximation Theory, 2014
We present a new semilocal convergence analysis of Newton- Tikhonov methods for solving ill-posed operator equations in a Hilbert space setting. Using more precise majorizing sequences and under the same computational cost as in earlier studies such as [
