Geometrical-based algorithm for variational segmentation and smoothing of vector-valued images
, 2007 An optimisation method based on a nonlinear functional is considered for segmentation and smoothing of vector-valued images. An edge-based approach is proposed to initially segment the image using geometrical properties such as metric tensor of the ...

On Affine Selections of Set–Valued Functions [PDF]
JAA, 1995 Abstract The main result of this paper is the theorem stating that every convex set–valued function F : I ↦ c(Y), where I ⊂ R is an interval and Y is a locally convex space, possesses an affine selection. In the case if Y = R and values of F are closed real intervals we can replace the assumption of convexity of F by the more general ...

Set-Valued Functions of Bounded Generalized Variation and Set-Valued Young Integrals [PDF]
Journal of Theoretical Probability, 2020 AbstractThe paper deals with some properties of set-valued functions having bounded Riesz p-variation. Set-valued integrals of Young type for such multifunctions are introduced. Selection results and properties of such set-valued integrals are discussed.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing

A Characterization of Cone-Convexity for Set-Valued Functions by Cone-Quasiconvexity
, 2015 A classical result by Crouzeix (1977) states that a real-valued function is convex if and only if any function obtained from it by adding a linear functional is quasiconvex.

Set-Valued Additive Functional Equations
Constructive Mathematical Analysis, 2019 In this paper, we introduce set-valued additive functional equations and prove the Hyers-Ulam stability of the set-valued additive functional equations by using the fixed point method.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

New Set-Valued Integral in a Banach Space
Journal of Function Spaces, 2015 We introduce and study a new set-valued integral of scalar-valued functions with respect to a set-valued measure in a Banach space. We investigate some properties and convergence theorems for this kind of integral.

On the Classes of Boolean Functions Generated by Maximal Partial Ultraclones
Известия Иркутского государственного университета: Серия "Математика", 2019 The sets of multifunctions are considered. A multifunction on a finite set $A$ is a function defined on the set $A$ and taking its subsets as values. Obviously, superposition in the usual sense does not work when working with multifunctions.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...
