Eccentricity sequences and eccentricity sets in digraphs
The eccentricity e(v) of a vertex v in a strongly connected digraph G is the maximum distance from v. The eccentricity sequence of a digraph is the list of eccentricities of its vertices given in nondecreasing order. A sequence of positive integers is a digraphical eccentric sequence if it is the eccentricity sequence of some digraph. A set of positive integers S is a digraphical eccentric set ...
متن کاملAverage Degree-Eccentricity Energy of Graphs
The concept of average degree-eccentricity matrix ADE(G) of a connected graph $G$ is introduced. Some coefficients of the characteristic polynomial of ADE(G) are obtained, as well as a bound for the eigenvalues of ADE(G). We also introduce the average degree-eccentricity graph energy and establish bounds for it.
متن کاملRadio detections during two state transitions of the intermediate-mass black hole HLX-1.
Relativistic jets are streams of plasma moving at appreciable fractions of the speed of light. They have been observed from stellar-mass black holes (~3 to 20 solar masses, M(⊙)) as well as supermassive black holes (~10(6) to 10(9) M(⊙)) found in the centers of most galaxies. Jets should also be produced by intermediate-mass black holes (~10(2) to 10(5) M(⊙)), although evidence for this third c...
متن کاملHLX in AML: novel prognostic and therapeutic target
Acute myeloid leukemia (AML) is an aggressive hematological malignancy with poor clinical outcome in most subtypes of the disease. Less than one third of patients achieve durable remission with current treatment regimens, and prognostication and risk stratification are challenging. We recently reported that a new non-clustered homeobox gene, H2.0-like homeobox (HLX), regulates early hematopoies...
متن کاملA minor merger scenario for the ultraluminous X-ray source ESO 243-49 HLX-1
The point-like X-ray source HLX-1 is the brightest known ultraluminous X-ray source and likely the strongest intermediate-mass black hole candidate. HLX-1 is hosted in the S0 galaxy ESO 243-49, but offset with respect to the nucleus, and its optical counterpart was identified with a massive star cluster. In this paper, we study, through N-body/smoothed particle hydrodynamics simulations, the sc...
