Numerical studies of amorphous silicon in harmonic approximation show that the highest 3.5% of vibrational normal modes are localized. As vibrational frequency increases through the boundary separating localized from delocalized modes, near ωc=70meV, (the “mobility edge”) there is a localization-delocalization (LD) transition, similar to a second-order thermodynamic phase transition. By a numer...

In light of recent debates on the existence a gigaparsec-scale structure traced by gamma-ray bursts, namely Hercules-Corona Borealis Great Wall (HCBGW), we revisit large-scale homogeneity in spatial distribution quasars. Our volume-limited sample quasars redshift range 1:6 < z ?2:1, which is constructed from data release 7 Sloan Digital Sky Survey quasar catalogue, covers about half suspecte...

The two-dimensional scaling Ising model in a magnetic field at critical temperature is integrable and possesses eight stable particles Ai (i = 1, . . . , 8) with different masses. The heaviest five lie above threshold and owe their stability to integrability. We use form factor perturbation theory to compute the decay widths of the first two particles above threshold when integrability is broke...

ab initio calculations at hf/6-31g* level of theory for geometry optimization and mp2/6-31g*//hf/6-31g* for a single point total energy calculation are reported for the importantenergy-minimum conformations and transition-state geometries of 1, 3-diazacyclohepta-1, 2-diene (2) and 1, 3-diazacycloocta-1, 2-diene (3). the c2 symmetric twist-chair (2-tc)conformation of 2 is calculated to be 7.4 kj...

Correspondence: [email protected] IBBR, 9600 Gudelsky Drive, 20850 Rockville, MD, USA Full list of author information is available at the end of the article The main text makes several claims about the OMS and the preceding views of the Mendelians that are not well known among scientists, or that contradict what one finds commonly in the evolutionary literature. Nevertheless, these claims are readi...

This article examines the representation of sustainability on online lifestyle site Goop as a case study how promotional media deal with environmental and social concerns. Specifically, paper presents intermediaries address or conceal tension between (1) promotion conspicuous consumption (2) advocacy sustainable living. The contributes to cultural intermediary scholarship by showing attempt rec...
