Monte Carlo (MC) simulation is widely recognized as an important technique to study the physics of particle interactions in nuclear medicine and radiation therapy. There are different codes dedicated to dosimetry applications ...

The Hansen-Coppens multipolar formalism was used to investigate the experimental electron density (ED) distribution of phthalonitrile derivative from single crystal X-ray data. The crystal displays C–H⋅⋅⋅O and O–H⋅⋅⋅N ...

In this work we present a comparative structural study of the 4-methyl-N-[(5-nitrothiophen-2-ylmethylidene)] aniline molecule using X-ray diffraction and theoretical ab initio methods. The title compound is considered as ...

In the present work the optimized molecular geometry and harmonic vibrational frequencies of chalcone derivative were calculated by DFT/B3LYP method with 6–31G (d,p) basis set. The vibrational assignments were performed ...

Regulation of heart rate variability (HRV) isdependent on the autonomicnervous system (ANS). The regulation is achieved by the two ANS activity branches distribution, namely the parasympathetic and the sympatheticactivities. ...
