Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Central nervous system (CNS) neuroblastoma, FOXR2‐activated, is a recently recognized entity in the WHO CNS5 classification, defined by activation of the FOXR2 transcription factor and unique histopathological features. This review synthesizes available literature and pooled clinical data, providing insight into demographics ...

Approximate Preservers on Banach Algebras and C*-Algebras
Abstract and Applied Analysis, 2013 The aim of the present paper is to give approximate versions of Hua’s theorem and other related results for Banach algebras and C*-algebras. We also study linear maps approximately preserving the conorm between unital C*-algebras.

Ant brood function as life preservers during floods.
PLoS ONE, 2014 Social organisms can surmount many ecological challenges by working collectively. An impressive example of such collective behavior occurs when ants physically link together into floating 'rafts' to escape from flooded habitat.

Linear Maps Preserving the Set of Semi-Weyl Operators
Mathematics, 2023 Let H be an infinite-dimensional separable complex Hilbert space and B(H) the algebra of all bounded linear operators on H. In this paper, we characterized the linear maps ϕ:B(H)→B(H), which are surjective up to compact operators preserving the set of ...

Preservers of the local spectral radius zero of Jordan product of operators
, 2021 Let B(X) be the algebra of all bounded linear operators on an infinite-dimensional complex Banach space X , and denote by rT (x) the local spectral radius of any operator T ∈ B(X) at any vector x ∈ X .

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

Itinéraires, 2011 This article explores the collective (cultural and linguistic) dimension of memory as realized in proverbs. These simple forms are called “frozen” because they are supposed to be the preservers of common sense in terms of intersubjectivity and mutual ...

Reachability Preservers: New Extremal Bounds and Approximation Algorithms [PDF]
ACM-SIAM Symposium on Discrete Algorithms, 2017 In this paper we prove new results about the extremal structure of paths in directed graphs. Say we are given a directed graph $G = (V, E)$ on $n$ nodes, a set of sources $S \subseteq V$ of size $|S|=n^{1/3}$, and a subset $P \subseteq S \times V$ of ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Type 1 plasminogen deficiency (PLGD‐1) is an ultra‐rare autosomal recessive disorder caused by variants in the PLG gene and affects approximately 1.6 individuals per million. The condition is characterized by decreased plasminogen levels and impaired function, resulting in fibrin‐rich lesions on mucous membranes throughout the body.

THE ROMA MUSICIANS OF MAGYARPALATKA AS PRESERVERS OF TRADITIONS
Studia Universitatis Babeş-Bolyai. Musica, 2017 Serving the community through playing music as a role, gradually was filled by gipsy musicians in the Carpathian basin, between the 18th and 20th century. Playing music became a profession and came in hand with a high reputation in society.
