Transitive Closure Preservers for Matrices over a Class of Semirings

Mathematics
We introduce the transitive closure operator Γ on the set of square matrices over a class of semirings, and then define the transitive closure of a matrix. We characterize the surjective linear transformations of matrices preserving (strongly preserving)

Latin-majorization and its linear preservers [PDF]

Sahand Communications in Mathematical Analysis, 2017
In this paper we study the concept of Latin-majorizati-\on. Geometrically this concept is different from other kinds of majorization in some aspects.

Unbounded Disjointness Preserving Linear Functionals [PDF]

Monatshefte f�r Mathematik, 2004
Let \(X\) and \(Y\) be locally compact Hausdorff spaces and let \(C_0(X)\) be the Banach space of continuous (real or complex-valued) functions on \(X\) vanishing at infinity. A linear operator \(T:C_0(X) \to C_0(Y)\) is called disjointness-preserving if \(fg=0\) implies \(T(f) T(g) =0\) for all \(f,g\in C_0(X).\) \textit{K. ~Jarosz} [Can. Math.

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

Pediatric 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 ...

Linear preservers on matrices

Linear Algebra and its Applications, 1987
Let \(M_ n(F)\) denote the set of \(n\times n\) matrices with entries in a field F. Linear maps \(L: M_ n(F)\to M_ n(F)\) are considered such that L(adj A)\(=adj(L(A))\) for all \(A\in M_ n(F)\) where F is infinite. For F equal to either the real or complex numbers linear maps are considered which preserve the idempotent matrices and satisfy \(L(I_ n ...

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Cubic Idempotence Preserver Problem in Hermitian Matrix Space

Journal of Harbin University of Science and Technology
Preserver problems are the study of preserving maps of certain invariants on a given mathematical structure. In order to preserve the cubic idempotent of Hermitian matrix space, we study the image from the basis of 2 × 2-dimensional Hermitian matrix ...

Psychosocial Functioning After Pediatric Bone Sarcoma: Generic and Survivor‐Specific Outcomes in Adolescent and Young Adult Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric bone sarcoma patients and survivors may experience psychosocial challenges related to childhood cancer after their intensive, body‐altering treatment. This cross‐sectional study aimed to evaluate generic and survivor‐specific psychosocial outcomes in a national cohort of pediatric bone sarcoma patients and survivors, and ...
