Computing Some Topological Indices of Two Kinds of Dendrimer Graphs Gn and Hn

open access: yesJournal of Mathematics
Dendrimer molecules are macromolecules which have many applications in nanosciences, drug delivery, biology, and different areas of sciences. Topological indices of chemical graph theory are numerical descriptor of a molecular structure.

Modelling of the Annual Mean Urban Heat Island Pattern for Planning of Representative Urban Climate Station Network

open access: yesAdvances in Meteorology, 2011
The spatial distribution of the annual mean urban heat island (UHI) intensity pattern was analysed for the medium-sized city Novi Sad, Serbia, located on the low and flat Great Hungarian Plain.

On the importance of shelter availability for reptiles provided by burrow‐digging ecosystem engineers: A systematic review and a case study

open access: yesJournal of Zoology, EarlyView.
In this article, we show that ground burrows influenced reptile populations inconsistently across both the 5‐year field study in the Kiskunság and the broader systematic review, which together revealed positive, negative, and neutral effects across species and habitat types.

The symmetric division Szeged index: A novel tool for predicting physical and chemical properties of complex networks

open access: yesHeliyon
This paper introduces a novel graph invariant, the symmetric division Szeged index (SDZ), which generalizes earlier concepts by focusing on vertices positioned closer to an edge's endpoints rather than vertex degrees.

Studying the corona product of graphs under some graph invariants [PDF]

open access: yesTransactions on Combinatorics, 2014
The corona product $Gcirc H$ of two graphs $G$ and $H$ is obtained by taking one copy of $G$ and $|V(G)|$ copies of $H$; and by joining each vertex of the $i$-th copy of $H$ to the $i$-th vertex of $G$, where $1 leq i leq |V(G)|$.

Long‐term stability of vertical bone augmentation in implant dentistry: A domain‐based review

open access: yesPeriodontology 2000, EarlyView.
Abstract Objectives Vertical ridge deficiency remains one of the most challenging conditions in preimplant surgery. Several techniques aim to restore lost vertical alveolar height, each with specific indications and limitations. Although these procedures often yield favorable short‐term outcomes with stable bone levels, their long‐term performance is ...

The ultrarapid delayed rectifier potassium current has important functional role in the repolarization reserve of canine and human ventricular muscle

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The ultrarapid delayed rectifier potassium current (IKur) has long been considered an atrial‐specific current with no functional role in the ventricles, despite evidence of its expression in ventricular myocytes. In the present study we challenged this prevailing concept and investigated the potential role of IKur in ventricular ...

Differences between the evaluation of thermal environment in shaded and sunny position

open access: yesHungarian Geographical Bulletin, 2016
Great attention has been paid in the last one and a half decade to the subjective evaluation of atmospheric conditions in different outdoor and semi-outdoor urban environments. Several field surveys were conducted all around the world in order to specify

Old dog, new trick: Charybdotoxin as a novel ryanodine receptor blocker

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The peptide toxin charybdotoxin (ChTx) from the scorpion Leiurus quinquestriatus was tested on single‐channel currents of the ryanodine receptor incorporated into planar lipid bilayers. The structure–function relationship of ChTx was investigated using toxin variants generated by isosteric substitutions of the basic amino acids ...
