Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Neuroblastoma (NB) with central nervous system (CNS) metastases is rare at diagnosis, but occurs more often during relapse/progression. Patients with CNS metastases face a dismal prognosis, with no standardized curative treatment available.

Natural star products on symplectic manifolds and quantum moment maps
, 2003 We define a natural class of star products: those which are given by a series of bidifferential operators which at order $k$ in the deformation parameter have at most $k$ derivatives in each argument.

A Duflo star product for Poisson groups [PDF]
, 2016 Let $G$ be a finite-dimensional Poisson algebraic, Lie or formal group. We show that the center of the quantization of $G$ provided by an Etingof-Kazhdan functor is isomorphic as an algebra to the Poisson center of the algebra of functions on $G$.

Modelling Collision Products of Triple-Star Mergers
, 2003 In dense stellar clusters, binary-single and binary-binary encounters can ultimately lead to collisions involving two or more stars. A comprehensive survey of multi-star collisions would need to explore an enormous amount of parameter space, but here we ...

Developmental Disorders in Children Recently Diagnosed With Cancer
Pediatric Blood &Cancer, EarlyView.ABSTRACT Neurocognitive deficits in adult survivors of childhood cancer are well established, but less is known about developmental disorders (DD) arising shortly after cancer diagnosis. Using 2016–2019 linked Ohio cancer registry and Medicaid data, we compared DD among 324 children with cancer and 606,913 cancer‐free controls.

Toeplitz Quantization and Asymptotic Expansions: Geometric Construction
Symmetry, Integrability and Geometry: Methods and Applications, 2009 For a real symmetric domain G_R/K_R, with complexification G_C/K_C, we introduce the concept of ''star-restriction'' (a real analogue of the ''star-products'' for quantization of Kähler manifolds) and give a geometric construction of the G_R-invariant ...

On star and acyclic coloring of generalized lexicographic product of graphs
AIMS Mathematics, 2022 A $ star \; coloring $ of a graph $ G $ is a proper vertex coloring of $ G $ such that any path of length 3 in $ G $ is not bicolored. The $ star \; chromatic \; number $ $ \chi_s(G) $ of $ G $ is the smallest integer $ k $ for which $ G $ admits a star ...

Annales de la Faculté des sciences de Toulouse : Mathématiques, 1995 The author presents an elementary proof of the existence theorem for \(*\)-products on a symplectic manifold originally due to \textit{M. de Wilde} and \textit{P. B. A. Lecomte} [Lett. Math. Phys. 7, 235-241 (1983; Zbl 0514.53031)]. The exposition is also based on unpublised work by Lecomte and de Wilde.

Non-formal star-exponential on contracted one-sheeted hyperboloids
, 2015 In this paper, we exhibit the non-formal star-exponential of the Lie group SL(2,R) realized geometrically on the curvature contraction of its one-sheeted hyperboloid orbits endowed with its natural non-formal star-product.
