Ewing Sarcoma in Infants and Children Under 2 Years of Age: A French Retrospective Study
Pediatric Blood &Cancer, EarlyView.ABSTRACT Ewing sarcoma, the second most common primary bone cancer in children, requires intensive treatment that may lead to significant long‐term sequelae, particularly in infants. We retrospectively analyzed data from 1621 French patients treated between 1988 and 2015 within the EW88/93/97 or EE99 trials, focusing on 17 infants diagnosed before 24 ...

Topological Aspects of Irredundant Intersections of Ideals and Valuation Rings [PDF]
, 2015 An intersection of sets \(A = \bigcap _{i \in I}B_i\) is irredundant if no \(B_i\) can be omitted from this intersection. We develop a topological approach to irredundance by introducing a notion of a spectral representation, a spectral space whose ...

Milnor K-theory of complete discrete valuation rings with finite residue fields [PDF]
Journal of Pure and Applied Algebra, 2015 Consider a complete discrete valuation ring O with quotient field F and finite residue field. Then the inclusion map O ↪ F induces a map K ˆ ⁎ M O → K ˆ ⁎ M F on improved Milnor K-theory. We show that this map is an isomorphism in degrees bigger or equal

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Pediatric thromboembolism is increasingly encountered in critical care. Systemic thrombolysis with tissue plasminogen activator (tPA) facilitates vessel or valve patency, yet pediatric‐specific protocols remain undefined, and safety concerns persist. Objective To evaluate the efficacy and safety of a tailored, prolonged systemic tPA

On Valuation Rings as Homomorphic Images of Valuation Domains. [PDF]
, 1982 A number of years ago, I. Kaplansky raised informally the question of whether every valuation ring could be expressed as a homomorphic image of a valuation domain.

A note on Computing SAGBI-Grobner bases in a Polynomial Ring over a Field [PDF]
Computer Science Journal of Moldova, 2006 In the paper [2] Miller has made concrete Sweedler's theory for ideal bases in commutative valuation rings (see [5]) to the case of subalgebras of a polynomial ring over a field, the ideal bases are called SAGBI-Grobner bases in this case.

Kaplansky's Problem on Valuation Rings [PDF]
Proceedings of the American Mathematical Society, 1989 The following theorem is proved in ZFC: there exist valuation rings which are not surjective homomorphic images of valuation domains. The proof relies on the existence of nonstandard divisible uniserial modules in ZFC. Let R be a valuation ring (in another terminology: a chained ring), i.e.

Some combinatorial number theory problems over finite valuation rings [PDF]
, 2015 Let $\mathcal{R}$ be a finite valuation ring of order $q^r$. In this paper we generalize and improve several well-known results, which were studied over finite fields $\mathbb{F}_q$ and finite cyclic rings $\mathbb{Z}/p^r\mathbb{Z}$, in the setting of ...

Global Efforts to Reduce Paediatric Cancer Care Disparities in Radiotherapy: A Decade Change
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background We present an update on the status, needs and challenges faced by paediatric imaging and radiotherapy (RT) programmes globally after a previous survey conducted by the International Atomic Energy Agency (IAEA) 10 years prior. Methods We developed and distributed a 121‐question survey to radiation oncologists, medical physicists and ...
