Additive maps preserving the scrambling index are bijective [PDF]

open access: yes, 2018
We prove that additive transformations on matrices over the binary Boolean semiring that preserve the scrambling index are automatically bijective. As a consequence we characterize such maps for matrices over an arbitrary antinegative semiring with ...

Symmetric Reverse n-Derivations on Ideals of Semiprime Rings

open access: yesAxioms
This paper focuses on examining a new type of n-additive map called the symmetric reverse n-derivation. As implied by its name, it combines the ideas of n-additive maps and reverse derivations, with a 1-reverse derivation being the ordinary reverse ...

Calabi–Yau structures on (quasi-)bisymplectic algebras

open access: yesForum of Mathematics, Sigma, 2023
We show that relative Calabi–Yau structures on noncommutative moment maps give rise to (quasi-)bisymplectic structures, as introduced by Crawley-Boevey–Etingof–Ginzburg (in the additive case) and Van den Bergh (in the multiplicative case). We prove along

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Zero-product preserving additive maps on symmetric operator spaces and self-adjoint operator spaces [PDF]

open access: yes, 2005
In this note, we characterize the additive maps on the space of symmetric operators and the space of self-adjoint operators which preserve zero-products in both directions, and the additive maps on the space of self-adjoint operators which preserve ...

Functional Inequalities Associated with Additive Mappings [PDF]

open access: yesAbstract and Applied Analysis, 2008
The functional inequality ∥f(x) + 2f(y) + 2f(z)∥ ≤ ∥2f(x/2 + y + z)∥ + ϕ  (x, y, z) (x, y, z ∈ G) is investigated, where G is a group divisible by 2, f : G → X and ϕ : G3 → [0, ∞) are mappings, and X is a Banach space. The main result of the paper states that the assumptions above together with (1) ϕ(2x, −x, 0) = 0 = ϕ(0, x, −x) (x ∈ G) and (2) limn ...

Health‐Related Social Needs in Children With Sickle Cell Disease Are Associated With Worse Health‐Related Quality of Life

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...

Additive rank-one nonincreasing maps on Hermitian matrices over the field GF(4) [PDF]

open access: yes, 2009
A complete classification of additive rank–one nonincreasing maps on hermitian matrices over Galois field GF(22) is obtained. This field is special and was not covered in a previouspaper. As a consequence, some known applications, like the classification

Assessment of laser power and scan speed influence on microstructural features and consolidation of AISI H13 tool steel processed by additive manufacturing [PDF]

open access: yes, 2020
Additive manufacturing can produce parts with complex geometries in fewer steps than conventional processing, which leads to cost reduction and a higher quality of goods.
