The retinal flow of information during locomotion provides cues to instantaneous heading. Reconciliation of observer trajectory with the internal representation of the environment implies that the positions of the centre of structure of global motion can be localized relative to points in the visual field. Humans are also sensitive to global structure in Glass patterns, which can approximate te...

We present GLASS, the Generator for Large Scale Structure, a new code simulation of galaxy surveys cosmology, which iteratively builds light cone with matter, galaxies, and weak gravitational lensing signals as sequence nested shells. This allows us to create deep realistic simulations at high angular resolution on standard computer hardware low resource consumption. GLASS also introduces techn...

Heavy metal oxide glasses, containing bismuth and/or lead in their glass structure are new alternatives for rare eart (RE) doped hosts. Hence, the study of the structure of these vitreous systems is of great interest for science and technology. In this research work, GeO(2)-PbO-Bi(2)O(3) glass host doped with Er(3+)/Yb(3+) ions was synthesized by a conventional melt quenching method. The Fourie...

A novel route was introduced to synthesize dense polyacrylamide (PAM) onto the glass slide surface. To investigate the surface chemistry of the PAM on the glass slides, X-ray photoelectron spectroscopy (XPS) was utilized to obtain detailed chemical state information on the PAM layer constituents. The XPS peak data were consistent with the presented model of the PAM on the glass slide surface. S...

In this paper, the coating on glass slides by ultrasonic irradiation in the aqueous ZnO solution is discussed. We investigate the effect of irradiation location on the amount coating, and the role of heat on the coated slide. The structure and morphology of the thin film were obtained by using atomic force microscopy (AFM) and field emission scanning electron microscopy (FESEM). The results sho...

Current understanding of the brittleness of glass is limited by our poor understanding and control over the microscopic structure. In this study, we used a pressure quenching route to tune the structure of silica glass in a controllable manner, and observed a systematic increase in ductility in samples quenched under increasingly higher pressure. The brittle to ductile transition in densified s...
