A connected edge-disjoint union Y of 102 tetrahedra (copies ofK4) is constructed which is Menger graph of a self-dual (1024)-configuration and K4-ultrahomogeneous. As Y is not a line graph, we ask whether there exists a non-line-graphical K4-ultrahomogeneous Menger graph of a self-dual (n4)-configuration which is connected edge-disjoint union of n copies of K4, for n / ∈ {42, 102}. Moreover, Y ...

BACKGROUND The International Neuroblastoma Pathology Classification (International Classification), which was established in 1999, is significant prognostically and is relevant biologically for the evaluation and analysis of patients with neuroblastic tumors (NTs). MYCN amplification is a known molecular marker for aggressive progression of NTs. These have been used together as important progno...

This paper describes an approach for the identification of flood-susceptible areas contributing to sustainability these in Giofiros river basin covering area 184 km2, located Southern Greece. is prone flooding with devastating consequences on people, environment, and economy. In this context, a geographic information system (GIS)–based multi-criteria decision analysis (MCDA) method potential fl...

Let G be a Lie group, g its Lie algebra, and Uh(g) the corresponding quantum group. We consider some examples of Uh(g)-invariant one and two parameter quantizations on G-manifolds.

The International Neuroblastoma Pathology Classification (INPC) has a prognostic impact that distinguishes two categories of neuroblastoma: favorable histology (FH) and unfavorable histology (UH). We analyzed 92 cases of neuroblastoma with the INPC evaluation and genomic grouping to investigate the correlation between the INPC and genomic signature, together with their prognostic significance. ...

BACKGROUND This study examined whether chronic neuropathic pain, modulated by a local anesthetic block, is associated with cortical magnetic field changes. METHODS In a group of 20 patients with pain caused by unilateral traumatic peripheral nerve injury, a local block with lidocaine 1% was administered and the cortical effects were measured and compared with a control group. The global field...

Abstract Nonlinear interactions involving electrostatic upper-hybrid (UH), ion-cyclotron (IC), lowerhybrid (LH), and Alfvén waves in quantum magnetoplasmas are considered. For this purpose, the quantum hydrodynamical equations are used to derive the governing equations for nonlinearly coupled UH, IC, LH, and Alfvén waves. The equations are then Fourier analyzed to obtain nonlinear dispersion re...

Despite their frequency in conversational talk, little is known about how ums and uhs affect listeners' on-line processing of spontaneous speech. Two studies of ums and uhs in English and Dutch reveal that hearing an uh has a beneficial effect on listeners' ability to recognize words in upcoming speech, but that hearing an um has neither a beneficial nor a detrimental effect. The results sugges...

CONTEXT Elevated free hemoglobin (Hb) and bilirubinemia complicate extracorporeal membrane oxygenation and could affect unfractionated heparin (UH) therapy monitoring by anti-Xa assay and activated partial thromboplastin time (aPTT). OBJECTIVES To compare in vitro response of anti-Xa and aPTT assays to UH in samples with artificial hyperbilirubinemia and hyperhemoglobinemia and to estimate if...

The notion of a C-ultrahomogeneous (or C-UH) graph, due to D. Isaksen et al., is adapted for digraphs and applied to the cubic distancetransitive graphs, considered as digraphs by replacing each edge by a pair of oppositely oriented arcs, with C formed by shortest oriented cycles and (k−1)-arcs with k = arc-transitivity. Moreover, (k−1)-powers of shortest cycles taken with orientation assignmen...
