Additivity of multiplicative maps on triangular rings

Linear Algebra and its Applications, 2011
A bijective map \(\sigma\) between rings is called an \(n\)-isomorphism if it satisfies \((x_1x_2\cdots x_n)^\sigma=x_1^\sigma x_2^\sigma\cdots x_n^\sigma\). Analogously one defines \(n\)-multiplicative derivations and \(n\)-elementary maps. Under certain technical restrictions it is shown that these maps are automatically additive on triangular rings.

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

Additive maps derivable or Jordan derivable at zero point on nest algebras [PDF]

, 2010
Let AlgN be a nest algebra associated with the nest N on a (real or complex) Banach space X. Assume that every N∈N is complemented whenever N-=N. Let δ:AlgN→AlgN be an additive map. It is shown that the following three conditions are equivalent: (1) δ is

New Results about Quadratic Functional Equation on Semigroups

Annales Mathematicae Silesianae
Let S be a semigroup, let (H, +) be a uniquely 2-divisible, abelian group and let φ, ψ be two endomorphisms of S that need not be involutive. In this paper, we express the solutions f : S → H of the following quadratic functional equation f(xφ(y))+f(ψ(y)

Additive mappings on symmetric matrices

Linear Algebra and its Applications, 2006
Let \(F_1\) and \(F_2\) be two fields and let \(S_n(F_1)\) and \(S_n(F_2)\) be the set of symmetric matrices over \(F_1\) and \(F_2\), respectively. A mapping \(\Phi: S_n(F_1)\to S_n(F_2)\) is called additive if \(\Phi(A+B)=\Phi(A)+\Phi(B)\). It is said that \(\Phi\) doesn't increase rank-one if \(rk(\Phi(A))\leq1\) whenever \(rk(A)=1\). \textit{M.

A Population‐Based Study on Childhood Aplastic Anemia—Incidence, Outcomes, and Health‐Related Quality of Life

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Childhood aplastic anemia (AA) is a rare disease, and both the disease itself and its treatment cause significant morbidity. We aimed to determine the contemporary incidence of childhood AA in Finland, to compare the clinical characteristics of AA against inherited bone marrow failure syndromes (IBMFS) and refractory cytopenia of ...

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...

Administering Blinatumomab via Continuous Intravenous Infusion in Pediatric Patients—A Single‐Institution Retrospective Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Blinatumomab, a CD19xCD3 bispecific T‐cell engager, has become standard therapy for children with de novo B‐cell acute lymphoblastic leukemia (B‐ALL). This retrospective review describes the experience of blinatumomab administration in pediatric patients.
