BACKGROUND Executive dysfunction has been observed in patients with left-sided anterior corona radiata infarction. However, whether left-sided posterior corona radiata infarction could cause executive dysfunction is unclear. Also, whether secondary damage in the left frontal white matter following ipsilateral posterior corona radiata infarct is causal or not and contributes to the occurrence an...

[1] There are compelling observations of a clear anticorrelation between solar wind flow speed and coronal electron temperature, as determined from solar wind ionic charge states. A simple theory is presented which can account for these observations, including the functional form of the correlation: Solar wind flow speed squared varies essentially linearly as the inverse of the coronal electron...

The interactions between nanosized particles and living systems are commonly mediated by what adsorbs to the nanoparticle in the biological environment, its biomolecular corona, rather than the pristine surface. Here, we characterize the adhesion toward the cell membrane of nanoparticles of different material and size and study how this is modulated by the presence or absence of a corona on the...

We calculate the radiation spectrum and its time variability of the black hole accretion disk-corona system based on the three-dimensional magnetohydrodynamic simulation. In explaining the spectral properties of active galactic nuclei (AGNs), it is often assumed that they consist of a geometrically thin, optically thick disk and hot, optically thin corona surrounding the thin disk. As for a mod...

We have recently shown that a ‘sphere+disk’ geometry Compton corona model provides a good description of Rossi X-ray Timing Explorer (RXTE) observations of the hard/low state of Cygnus X–1. Separately, we have analyzed the temporal data provided by RXTE. In this paper we consider the implications of this timing analysis for our best-fit ‘sphere+disk’ Comptonization models. We focus our attentio...

This publication presents the results of a series of laboratory investigations on the DC ion current coupling between nearby AC and DC conductors, which is an important consideration in the design of hybrid AC/DC transmission towers. The corona activity depends on the surface condition of the conductor. Whether or not the conductors produced corona was controlled by selectively wetting them. Th...

BACKGROUND We introduce a promising methodology to identify new therapeutic targets in cancer. Proteins bind to nanoparticles to form a protein corona. We modulate this corona by using surface-engineered nanoparticles, and identify protein composition to provide insight into disease development. METHODS/PRINCIPAL FINDINGS Using a family of structurally homologous nanoparticles we have investi...

PURPOSE To correlate the location of large subcortical infarcts with the site of cerebrovascular occlusive disease. METHODS We examined CT and angiographic findings of 38 patients with major arterial occlusive disease and newly developed large subcortical infarcts of 2.0 cm or more, which were classified into three types: striatocapsular infarcts in the basal ganglia, terminal supply area inf...

There is reason to suspect that about half of the baryons are in pressure-supported plasma in the halos of normal galaxies, drawn in by gravity along with about half of the dark matter. To be consistent with the observations this baryonic component, the corona, would have to be hotter than the kinetic temperature of the dark matter in the halo so as to produce acceptable central electron densit...

In the paper characteristic features of the corona noise from UHV transmission lines have been distinguished, which can be useful for the noise measurement under high level interference conditions. The utility of statistical methods in elimination of typical environmental interference has been shown, particularly methods based on the measurement of statistical spectra. The effect of inaccurate ...
