Antiplasmodial activity of p-substituted benzyl thiazinoquinone derivatives and their potential against parasitic infections [PDF]

open access: yes, 2020
Malaria is a life-threatening disease and, what is more, the resistance to available antimalarial drugs is a recurring problem. The resistance of Plasmodium falciparum malaria parasites to previous generations of medicines has undermined malaria control ...

Exact trace formulae for a class of one-dimensional ray-splitting systems [PDF]

open access: yes, 2001
Based on quantum graph theory we establish that the ray-splitting trace formula proposed by Couchman {\it et al.} (Phys. Rev. A {\bf 46}, 6193 (1992)) is exact for a class of one-dimensional ray-splitting systems.

Predictions of melting, crystallization, and local atomic arrangements of aluminum clusters using a reactive force field [PDF]

open access: yes, 2008
A parametrized reactive force field model for aluminum ReaxFFAl has been developed based on density functional theory (DFT) data. A comparison has been made between DFT and ReaxFFAl outputs to ascertain whether ReaxFFAl is properly parametrized and to ...

Computing Degree Based Topological Properties of Third Type of Hex-Derived Networks

open access: yesMathematics, 2019
In chemical graph theory, a topological index is a numerical representation of a chemical network, while a topological descriptor correlates certain physicochemical characteristics of underlying chemical compounds besides its chemical representation. The

Hybridization and spin-orbit coupling effects in quasi-one-dimensional spin-1/2 magnet Ba3Cu3Sc4O12 [PDF]

open access: yes, 2016
We study electronic and magnetic properties of the quasi-one-dimensional spin-1/2 magnet Ba3Cu3Sc4O12 with a distinct orthogonal connectivity of CuO4 plaquettes.

Performance of 3D-space-based atoms-in-molecules methods for electronic delocalization aromaticity indices [PDF]

open access: yes, 2010
Several definitions of an atom in a molecule (AIM) in three-dimensional (3D) space, including both fuzzy and disjoint domains, are used to calculate electron sharing indices (ESI) and related electronic aromaticity measures, namely, Iringand multicenter ...

Adapting the Interrelated Two-way Clustering method for Quantitative Structure-Activity Relationship (QSAR) Modeling of a Diverse Set of Chemical Compounds

open access: yes, 2013
Interrelated Two-way Clustering (ITC) is an unsupervised clustering method developed to divide samples into two groups in gene expression data obtained through microarrays, selecting important genes simultaneously in the process.

Topology, connectivity and electronic structure of C and B cages and the corresponding nanotubes

open access: yes, 2003
After a brief discussion of the structural trends which appear with increasing number of atoms in B cages, a one-to one correspondence between the connectivity of B cages and C cage structures will be proposed.
