Contextual elements can fundamentally change the perception of an embedded target. A recently discovered masking effect, shine-through, allows one to investigate the precise dynamics of contextual modulation of the human visual system. In this shine-through effect, a vernier precedes a grating comprising more than seven elements for display times as short as 10 ms. The vernier appears as a "shi...

The nifLA operon of Klebsiella pneumoniae encodes the sensor-activator pair involved in the regulation of other nif genes. Balanced synthesis of both proteins, which is required for correct regulation, is achieved by coupling translation of nifA to that of nifL. The mechanism of translational coupling at the nifLA operon was analysed using a specialized ribosome system, and the effect of substi...

We propose shiny analysis framework accompanied with makeup deterioration using normalized facial images (MaVIC and the corresponding makeup-deteriorated data sets). These images are analyzed and reconstructed based on principal component analysis (PCA) and then the differential ones between the reconstruction images with different numbers of PCA components can be generated. The shiny Eigen-fac...

Most models of vision focus either on the spatial or temporal aspects of visual processing and neglect the other component. A variety of studies have shown, however, that spatial and temporal processing cannot easily be separated. The shine-through effect has proven to be a sensitive tool to study spatio-temporal processing. Two very different dynamical models, the 3D-LAMINART and the WCTM mode...

Over the past several years there has been growing interest in the high prevalence of vitamin D deficiency in both the general population and among people living with HIV infection. Vitamin D deficiency in the setting of HIV infection is likely multi-factorial with contributions from environmental factors as well as possible associations with HIV therapy. This lecture will highlight recent data...

It has become axiomatic that backbench MPs at Westminster have limited the capacity for independent action under burdens of constituency business and whipped votes. Even avenues available such to shine, as select committees, are often illusory, because parliamentarians little time prepare materials or brief themselves on any but highest profile witnesses. The political parties benefited from th...

The article is devoted to the phenomenon of embroidering folklorized poetic works by Taras Shevchenko on towels (rushnyky), many which belong patriotic inscriptions (for most part, Western Ukraine, 1930s). These lines could be in a variety contaminations. Embroideresses often combined between two and four different works, therefore creating an absolutely new text. Particularly, I demonstrate ru...

Scintigraphic images are strongly affected by Poisson noise. This article presents the results of a comparison between denoising methods for Poisson noise according to different criteria: the gain in signal-to-noise ratio, the preservation of resolution and contrast, and the visual quality. The wavelet techniques recently developed to denoise Poisson noise limited images are divided into two gr...

PURPOSE This work aimed at quantifying the gains in spatial resolution and noise that could be achieved when using resolution modelling based on a multi-ray approach and additionally the Statistical and Heuristic Noise Extraction (SHINE) method in human pinhole single photon emission tomography (PH-SPECT). METHODS PH-SPECT of two line phantoms and one homogeneous cylinder were recorded using ...
