Estimations of the best M-term approximations of functions in the Lorentz space with constructive methods

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2017
This paper considers the Lorentz space of periodic functions of many variables with the anisotropic norm, of functional Nikol’skii-Besov’s class and of the best M -term approximation of function.

Approximation algorithms [PDF]

open access: yesProceedings of the National Academy of Sciences, 1997
Increasing global competition, rapidly changing markets, and greater consumer awareness have altered the way in which corporations do business. To become more efficient, many industries have sought to model some operational aspects by gigantic optimization problems. It is not atypical to encounter models that capture 10 6

Serological Benefit of SARS‐CoV‐2 Vaccination Relative to Infection in Children With Acute Lymphoblastic Leukemia

open access: yesPediatric 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.

A Comparative Study of Approximations for Perturbation Analysis of Principal Components

open access: yesMethodology
Principal component analysis is a well known method for dimension reduction based on the covariance matrix associated to a multivariate data table. Therefore, a large amount of work has been devoted to analyzing the sensitivity of the eigenstructure of ...

Linear stationary iterative methods for the force-based quasicontinuum approximation [PDF]

open access: yes, 2012
Force-based multiphysics coupling methods have become popular since they provide a simple and efficient coupling mechanism, avoiding the difficulties in formulating and implementing a consistent coupling energy.

Approximating the girth [PDF]

open access: yesProceedings of the Twenty-Second Annual ACM-SIAM Symposium on Discrete Algorithms, 2011
This article considers the problem of computing a minimum weight cycle in weighted undirected graphs. Given a weighted undirected graph G = ( V , E , w ), let C be a minimum weight cycle of G , let

Increased Risk of Sarcomas in Children With Congenital Anomalies: Findings From the Genetic Overlap Between Anomalies and Cancer in Kids (GOBACK) Registry Linkage Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated. Procedure We

Supporting Survivor‐Centered Care Through Digital Health Integration

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Survivors of childhood cancer face barriers to receiving guideline‐based, long‐term follow‐up care. Two digital tools, Passport for Care (PFC) and Cancer SurvivorLink (SurvivorLink), address complementary gaps by enabling tailored survivorship care plan (SCP) generation, updating, storage, and sharing.

Approximations of non-homogeneous Markov chains on abstract states spaces

open access: yesBulletin of Mathematical Sciences, 2021
Approximations of nonhomogeneous discrete Markov chains (NDMC) play an essential role in both probability and statistics. In all these settings, it is crucial to consider random variables in appropriate spaces.
