The crossing number of satellite knots
, 2014 We show that the crossing number of a satellite knot is at least 10^{-13} times the crossing number of its companion ...

Nonplanarity of Iterated Line Graphs
Journal of Mathematics, 2020 The 1-crossing index of a graph G is the smallest integer k such that the kth iterated line graph of G has crossing number greater than 1. In this paper, we show that the 1-crossing index of a graph is either infinite or it is at most 5.

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

, 2012 The exact crossing number is known only for a few specific families of graphs. Cartesian products of two graphs belong to the first families of graphs for which the crossing number has been studied. Let Pn be a path with n+1 vertices. Pnk, the k-power of

Various heuristic algorithms to minimise the two-page crossing numbers of graphs
Open Computer Science, 2015 We propose several new heuristics for the twopage book crossing problem, which are based on recent algorithms for the corresponding one-page problem. Especially, the neural network model for edge allocation is combined for the first time with various one-

Molecular Oncology, EarlyView.Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

, 2008 A longstanding problem of crossing number, Zarankiewicz’s conjecture, asserts that the crossing number of the complete bipartite graph Km,n is ⌊m2⌋⌊m−12⌋⌊n2⌋⌊n−12⌋, which is known only for m≤6. It is natural to generalize Zarankiewicz conjecture and ask:

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer
Molecular Oncology, EarlyView.COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...

ON THE SATELLITE CROSSING NUMBER CONJECTURE
, 2011 We prove some estimates on the crossing number of satellites of adequate, and partly of semiadequate knots. We mostly deal with classical cables, obtaining the first examples where the asymptotic cable crossing number is shown to be equal to the ...

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma
Molecular Oncology, EarlyView.The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...
