in a typical solitonic distribution, the soliton density is distributed over the entire moleculeand the present work shows how its density can be decomposed into solitonic and antisolitoniccomponents. it is found that there exists a unique electron as soliton over the anionicnanoconductor, while there are many other solitons and antisolitons. the solitonic states are furtherdecomposed to the ca...

False data injection attack and PDoS (path-based Denial of Service) attack are serious threats in wireless sensor networks. Existing schemes can effectively resist false data injection and PDoS attacks, but most of them can not find out the compromised node when the base station or sink node detect the report is invalid. In this paper, we propose a false data injection-resilient security routin...

The main interaction between pyridine and zeolites leads to form a hydrogen bond between the N atom of pyridine and OH groups of zeolites. The present work reports a theoretical study about the structural, vibrational and topological properties of the charge distribution of the molecular complexes between pyridine and a series of acids sites of zeolites. The calculated structural parameters...

A DFT study of the electronic properties of ansa-titanocene dichloride is reported. Molecular orbital analysis, polarizability, hyperpolarizability, thermodynamic analysis and natural bond orbital (NBO) theory are the main aim of the present research. The computed structural parameters show a good agreement with the similar experimental results. The calculated HOMO and LUMO energies show that c...

The Density Functional Theory (DFT) and the Natural Bond Orbital (NBO) calculations basedmethod B3LYP/6-31G* were carried out to study the interaction of carbon nanotube (8,0) withnitrobenzene in two situations perpendicular and parallel. Formation energies of compounds,charges, the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular'orbital (LUMO) and the HOMO-LUMO ba...

The vibrational, electronic properties of 2-chloro-5-nitrobenzophenone (2C5NB) are explored experimentally, and theoretically (DFT) using B3LYP functional with LanL2DZ basis set. This has been performed for assignment vibrational frequencies that conjointly involves inserting beneficial evidence concerning the structure chosen compound. Based on PED, a comprehensive clarification FT-Infrared FT...

Experimental and theoretical studies, of the Fe-partial phonon density of states (PDOS) for Fe52.5Cr47.5 alloy having alpha and sigma phases were carried out. The former using the nuclear resonant inelastic x-ray scattering method, and the latter with the direct one. Characteristic features of PDOS, which distinguish one phase from the other, were revealed and successfully reproduced by the the...
