The electronic states of FeSin −/0/+ (n = 1-2) clusters have been investigated with DFT, CASPT2, and DMRGCASPT2 methods. By using relatively large active spaces, the DMRG-CASPT2 method is found to provide highly accurate relative energies for the various relevant electronic states. Leading configurations, bond distances, harmonic vibrational frequencies, and relative energies for the low-lying states of the title clusters are reported.

The limits of current micro-scale technology is approaching rapidly. As the technology is going toward nano-scale devices, physical phenomena involved are fundamentally different from micro-scale ones. Principles in classical physics are no longer powerful enough to explicate the phenomena involved in nano-scale devices. At this stage, quantum mechanic sheds some light on those topics which cannot be described by classical physics. The primary focus of this research work is the development of an analysis technique for understanding the behavior of strongly perturbed harmonic oscillators.

This study provides comparative findings on the impact of adoption of International Financial Reporting Standards (IFRSs) on the value relevance of reported accounting and non-accounting information in a set of six countries with a British accounting heritage but divergent harmonization paths leading up to IFRS adoption. The countries included in the sample are the United Kingdom, Australia, Hong Kong, Singapore, Malaysia and South Africa.

We will show that Schrodinger equations for low-dimensional systems can be solved by the method of quantum Diffusion Monte Carlo (DMC). The wave function and energy in a ground state are found for the two-dimensional harmonic oscillator, quantum wells, quantum wires and quantum dots. This is great approach for problems of low-dimensional systems. In this paper, the sign of the wave function is not treated.

Sum frequency generation (SFG) spectra of cotton cellulose fibers were successfully obtained with IR wavenumber from 2800 to 3400 cm-1 . The spectra showed the two peaks at 2840 cm-1 and 2941 cm-1 assigned to symmetric and asymmetric CH2 stretching modes, respectively. There was also a peak obtained at wavenumber 2959 cm-1 assigned to the overtone of H-O-C bending at Fermi resonance with 2941 cm-1 peak.
