Maximum values of Szeged index and edge-Szeged index of graphs

Electronic Notes in Discrete Mathematics, 2009
AbstractThe Szeged index is a graph invariant which is a natural generalization of Wienerindex. In this note, we disprove two recent conjectures concerning with the maxi-mum value of Szeged index of graphs, which are due to Khalifeh et al. (Europ. J.Combinatorics (2008), doi:10.1016/j.ejc.2008.09.019) and respectively, to Gutmanet al. (Groat.

Weighted Szeged indices of some graph operations [PDF]

Transactions on Combinatorics, 2016
In this paper, the weighted Szeged indices of Cartesian product and Corona product of twoconnected graphs are obtained. Using the results obtained here, the weighted Szeged indices ofthe hypercube of dimension n, Hamming graph, C4 nanotubes, nanotorus ...

A New Alternative to Szeged, Mostar, and PI Polynomials—The SMP Polynomials

Mathematics, 2023
Szeged-like topological indices are well-studied distance-based molecular descriptors, which include, for example, the (edge-)Szeged index, the (edge-)Mostar index, and the (vertex-)PI index.

A time-variant norm constrained interpolation problem arising from relaxed commutant lifting

, 2008
A time-variant analogue of an interpolation problem equivalent to the relaxed commutant lifting problem is introduced and studied. In a somewhat less general form the problem already appears in the analysis of the set of all solutions to the three chain ...

Psychopathy traits and their link to emotion recognition impairments in conduct disorder

JCPP Advances, EarlyView.
Abstract Background Neurocognitive models suggest that callous‐unemotional (CU) traits in youths with conduct disorder (CD) are linked to emotion recognition impairments, particularly in identifying distress emotions like fear and sadness. However, CD may be accompanied by grandiose‐manipulative (GM) and/or impulsive‐irresponsible (II) traits in ...

The relationship between built-up areas and the spatial development of the mean maximum urban heat island in Debrecen, Hungary [PDF]

, 2005
The climate of built-up regions differs significantly from rural regions and the most important modifying effect of urbanization on local climate is the urban temperature excess, otherwise called the urban heat island (UHI).

Predicting peri‐implantitis incidence and implant failure via risk‐assessment and prognostication tools: A validation study

Journal of Periodontology, EarlyView.
Abstract Background Identifying individuals at high risk for developing peri‐implantitis (PI) and then determining the prognosis for implants with PI is crucial for treatment planning. Methods This study longitudinally followed implants from implant placement retrospectively.

RNA elements directing in vivo assembly of the 7SK/MePCE/Larp7 transcriptional regulatory snRNP [PDF]

, 2013
Through controlling the nuclear level of active positive transcription elongation factor b (P-TEFb), the 7SK small nuclear RNA (snRNA) functions as a key regulator of RNA polymerase II transcription.

Deep learning cone‐beam computed tomography image segmentation for the 3D visualization of mandibular infraosseous periodontal defects

Journal of Periodontology, EarlyView.
Abstract Background The accurate assessment of infraosseous periodontal defects is crucial for effective diagnosis and treatment planning. Cone‐beam computed tomography (CBCT) enables detailed imaging of these defects; however, to leverage their full potential, CBCT images must be reconstructed in 3 dimensions (3D).
