We model the growth of Ag films deposited on Ag(100) below 140K. Our recent VariableTemperature Scanning Tunneling Microscopy {VTSTM) studies reveal "smooth growth" from 120-140K, consistent with earlier diffraction studies. However, we also find rougher growth for lower temperatures. This unexpected behavior is modeled by describing the deposition dynamics using a "restricted downward funnelin...

The optical destruction thresholds of conventionally etched and tube-etched near-field optical probes were measured. One of the main advantages of tube-etched tips is their smooth glass surface after taper formation. Presumably for this reason, a destruction limit of over 120 microJ was obtained, almost twice as large as that of the rougher, conventionally etched fibre probes. The use of additi...

The intermittent behavior of the space-scale distribution of Lyα transmitted flux of QSO HS1700+64 has been analyzed via a discrete wavelet transform. We found that there are strong indications of intermittency on scales down to about 10 h kpc. These are: 1.) the probability distribution function of the local fluctuations of the flux is significantly long-tailed on small scales, and 2.) the loc...

The aim of this work is to describe the behavior of a device capable to generate high frequency (∼ THz) acoustic phonons. This device consists in a GaAs-AlGaAs double barrier heterostructure that, when an external bias is applied, produces a high rate of longitudinal optical LO phonons. These LO phonons are confined and they decay by stimulated emission of a pair of secondary longitudinal optic...

In the present work we have investigated the relationships existing between the optical properties and the growth mechanism, microstructure and surface roughness of SnO2 and ZnO oxide films prepared by magnetron sputtering under conditions resembling those utilized in industry. Thin films of these oxides with different thicknesses were characterized by atomic force microscopy, glancing incidenc...

This paper considers possible price paths of a financial security in an idealized market. Its main result is that the variation index of typical price paths is at most 2; in this sense, typical price paths are not rougher than typical paths of Brownian motion. We do not make any stochastic assumptions and only assume that the price path is right-continuous. The qualification “typical” means tha...

The present study evaluates the effects of syrup concentrations of natural raisin microflora culture on the characteristics of sourdough and sourdough bread. The original total titratable acidity (TTA) of the starter solutions were between 10.30 and 10.45 mL, after 96 hours of incubation, the TTA of the starter solution increased to 11.30-11.85 mL. The greatest pH decrease and TTA increase occu...

We construct local solutions to the Yang–Mills heat flow (in DeTurck gauge) for a certain class of random distributional initial data, which includes 3D Gaussian free field. The main idea, goes back work Bourgain as well Da Prato–Debussche, is decompose solution into rougher linear part and smoother nonlinear part, control latter by probabilistic arguments. In companion work, we use results thi...

This work examined the influence of dual incorporation MoO2 and SiO2 on corrosion behavior pure titanium treated via plasma electrolytic oxidation (PEO). To achieve this purpose, substrate was PEO in an alkaline-molybdate electrolyte without with nanoparticles. The microstructural observation revealed that addition nanoparticles into during helped to seal structural defects coating so a rougher...

This paper presents the results of a study on high-temperature oxidation characteristics after mechanical and laser removal TA15 titanium alloy oxide film. The morphology, components, roughness surface were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), photoelectron spectroscopy (XPS) confocal (OM). film can be effectively removed with grinding cleaning, is thick...
