On 3-Colorings of Direct Products of Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
The k-independence number of a graph G, denoted as αk(G), is the order of a largest induced k-colorable subgraph of G. In [S. Špacapan, The k-independence number of direct products of graphs, European J. Combin.

Estimation of Laplacian spectra of direct and strong product graphs

open access: yes, 2015
Calculating a product of multiple graphs has been studied in mathematics, engineering, computer science, and more recently in network science, particularly in the context of multilayer networks. One of the important questions to be addressed in this area

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

Some Notes on Higher Frobenius–Schur Indicators of the Regular Representations for Matched Pairs of Groups

open access: yesMathematics
The notion of matched pair (F,G,▹,◃) of finite groups was introduced by Takeuchi in 1981, which is equivalent to a factorization of the group F⋈G. We find in this paper some sufficient conditions when equations νm(F⋈G)=νm(F)νm(G) for all m≥0 imply that F⋈

Dynamical properties of direct products of discrete dynamical systems

open access: yesЖурнал Средневолжского математического общества, 2022
A natural way for creating new dynamical systems is to consider direct products of already known systems. The paper studies some dynamical properties of direct products of homeomorphisms and diffeomorphisms.

Stability in orbit equivalence for Baumslag-Solitar groups and Vaes groups

open access: yes, 2013
A measure-preserving action of a discrete countable group on a standard probability space is called stable if the associated equivalence relation is isomorphic to its direct product with the ergodic hyperfinite equivalence relation of type II_1.

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Intravitreal GD2‐Specific Chimeric Antigen Receptor T‐Cell Therapy for Refractory Retinoblastoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Effective treatments for advanced, treatment‐resistant retinoblastoma (RB) remain limited. GD2‐specific chimeric antigen receptor (CAR) T cells show potent antitumor activity with minimal toxicity but have not previously been evaluated in RB.

2-Tone Colorings in Graph Products

open access: yesDiscussiones Mathematicae Graph Theory, 2015
A variation of graph coloring known as a t-tone k-coloring assigns a set of t colors to each vertex of a graph from the set {1, . . . , k}, where the sets of colors assigned to any two vertices distance d apart share fewer than d colors in common.

Reduced direct products [PDF]

open access: yesFundamenta Mathematicae, 1962
Verff. beschreiben die grundlegenden mengentheoretischen und modelltheoretischen Eigenschaften des reduzierten Produkts, einer Konstruktion von Modellen aus Modellen. Das reduzierte Produkt -- ein spezieller Quotient des direkten Produkts -- geht auf die ,,champs logiques'' von \textit{J. Łoś} [Math.
