Synthesis of sexual selection: a systematic map of meta‐analyses with bibliometric analysis

open access: yesBiological Reviews, Volume 99, Issue 6, Page 2134-2175, December 2024.
ABSTRACT Sexual selection has been a popular subject within evolutionary biology because of its central role in explaining odd and counterintuitive traits observed in nature. Consequently, the literature associated with this field of study became vast.

Quantum space and quantum completeness

open access: yes, 2018
Motivated by the question whether quantum gravity can "smear out" the classical singularity we analyze a certain quantum space and its quantum-mechanical completeness.

Boson-fermion unification, superstrings, and Bohmian mechanics

open access: yes, 2009
Bosonic and fermionic particle currents can be introduced in a more unified way, with the cost of introducing a preferred spacetime foliation. Such a unified treatment of bosons and fermions naturally emerges from an analogous superstring current ...

Theoretical Concepts for the Morphology Study of Insects Using Topological Descriptors [PDF]

open access: yes
Since they aid in the pollination of sexually reproducing plants and boost agricultural yields for human consumption, insects are a crucial component of the ecosystem\u27s fauna. The current work\u27s primary goal was to determine the order of insects by

Differential-Algebraic Equations and Beyond: From Smooth to Nonsmooth Constrained Dynamical Systems [PDF]

open access: yes, 2018
The present article presents a summarizing view at differential-algebraic equations (DAEs) and analyzes how new application fields and corresponding mathematical models lead to innovations both in theory and in numerical analysis for this problem class ...

Graph Invariants of Trees with Given Degree Sequence [PDF]

open access: yes, 2017
Graph invariants are functions defined on the graph structures that stay the same under taking graph isomorphisms. Many such graph invariants, including some commonly used graph indices in Chemical Graph Theory, are defined on vertex degrees and ...

Reformulated Zagreb Indices of Some Cycle-Related Graphs and Linear [n]-Phenylenes

open access: yesOsmaniye Korkut Ata Üniversitesi Fen Bilimleri Enstitüsü Dergisi
Graph invariants (topological indices) are numerical values of graphs obtained from 2-dimensional (2-D) images of chemical structures. These invariants are used in the structure-property/activity studies to predict certain properties such as the enthalpy of vaporization, and stability of molecular structures. In this paper, reformulated Zagreb indices,

SOMBOR INDEX AND ITS GENERALIZATION OF POWER GRAPH OF SOME GROUP WITH PRIME POWER ORDER [PDF]

open access: yes
Graphs are an intriguing topic of discussion due to their numerous applications, particularly in chemistry. Topological indices derived from graph representations of molecules enable us to predict various properties of these compounds, including their ...
