An inequality for partially ordered sets
The pair of (P,f) is called a real partially ordered set if P is a partially ordered set and f: \(P\to {\mathbb{R}}^+\) is a function from P to the positive real numbers. For a subset \(T\subseteq P\) define \(Id^ f(P)=\sum \{f(I):\) I ideal and \(T\subseteq I\}\).

ABSTRACT Introduction Nephrogenic rests (NRs) and nephroblastomatosis (NBM) are precursor lesions for development of Wilms tumor (WT). Their association with the risk of relapse has not been properly assessed, partly due to misunderstanding of their diagnostic criteria and terminology.

ABSTRACT Background Sickle cell disease (SCD) has undergone major changes in the last decades. Its prevalence has been steadily increasing and numerous advances have been made in the management of the disease. However, the effect in real‐life setting of these major changes is unknown, particularly in a Canadian environment. Procedure We aimed to assess

n–ary hyperstructures constructed from binary quasi–ordered semigroups
Based on works by Davvaz, Vougiouklis and Leoreanu-Fotea in the field of n–ary hyperstructures and binary relations we present a construction of n–ary hyperstructures from binary quasi-ordered semigroups.

The morphology of partially ordered sets
DEFINITION. XC gn is called a set of incomparable elements if A, B E X and A C B imply A = B. Then Sperner’s Theorem -maxx / X 1 = (,J,,), where X ranges over all sets of incomparable elements in .?3,, . The standard proof of Sperner’s theorem (see Harper-Rota [lo]) is based upon two properties of an , unimodality and matching.

ABSTRACT Ewing sarcoma (ES) and rhabdomyosarcoma (RMS) are aggressive malignancies in children and adolescents where metastases impact prognosis. 18F‐fluoro‐2‐deoxy‐d‐glucose positron emission tomography/computed tomography (FDG‐PET/CT) and bone marrow aspirate and trephine biopsies (BMAT) are used to identify disease involvement.

In this article, we consider the nonlinear fractional order three-point boundary-value problem $$displaylines{ D_{0+}^{alpha} u(t) + f(t,u(t))=0, quad 0 < t < 1,cr u(0) = u'(0) = dots = u^{(n-2)}(0)=0, quad u^{(n-2)}(1) = int_0^eta u(s)ds, }$$

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.
