Ovarian Sex Cord Stromal Tumors in Children and Adolescents—The European Standard Clinical Practice Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT As part of the European Cooperative Study Group for Paediatric Rare Tumours initiative, we developed standard clinical practice guidelines for ovarian sex cord stromal tumors, based on comprehensive national and international cohort analyses, literature review, and a final expert consensus conference.

Matroids on Partially Ordered Sets

Advances in Applied Mathematics, 1998
The concept of a matroid is known to be a fundamental concept in combinatorics and it is also known to be ubiquitous in mathematics in general (e.g., stratification of Grassmanians, arrangements of hyperplanes, optimization). In the literature there exist attempts to generalize this concept.

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Soft constraints with partially ordered preferences [PDF]

, 2020
This paper constructs a logic of soft constraints where the set of degrees of preference forms a partially ordered set. When the partially ordered set is a distributive lattice, this reduces to the idempotent semiring-based CSP approach, and the lattice ...

Contractibility of Solution Sets in Partially Ordered Semi-infinite Set Optimization

Journal of Optimization, Differential Equations and Their Applications
This paper studies contractibility of m-efficient and weak m-efficient solution sets in the context of semi-infinite set optimization with respect to a partial set order relation.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Extensions of a Partially Ordered Set [PDF]

, 1967
In this thesis we introduce the concept of a dense extension of a partially ordered set and study some of the properties of the resulting class of extensions.

Association Between Individualized Education for Kidney Replacement Therapy Modality Selection and Peritoneal Dialysis Initiation: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) is an established home‐based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD.

A new class of generalized contraction using P-functions in ordered metric spaces

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
In this paper, we introduced and studied a new class of mappings in ordered metric spaces that is inspired from the concept of a P-function introduced in Chaipunya et. al. [10].

Orthomodular Lattices Induced by the Concurrency Relation [PDF]

Electronic Proceedings in Theoretical Computer Science, 2009
We apply to locally finite partially ordered sets a construction which associates a complete lattice to a given poset; the elements of the lattice are the closed subsets of a closure operator, defined starting from the concurrency relation. We show that,
