OBJECTIVE High-density electroencephelography (EEG) can provide an insight into human brain function during real-world activities with walking. Some recent studies have used EEG to characterize brain activity during walking, but the relative contributions of movement artifact and electrocortical activity have been difficult to quantify. We aimed to characterize movement artifact recorded by EEG...

let $d$ be a digraph with vertex set $v(d)$. for vertex $vin v(d)$, the degree of $v$,denoted by $d(v)$, is defined as the minimum value if its out-degree and its in-degree.now let $d$ be a digraph with minimum degree $deltage 1$ and edge-connectivity$lambda$. if $alpha$ is real number, then the zeroth-order general randic index is definedby $sum_{xin v(d)}(d(x))^{alpha}$. a digraph is maximall...

Solid modeling has been recognized as a powerful computer -aided design tool, being informationally complete and semantically well-formed. However, it is insufficient by itself to support the design process of complex artifacts such as buildings , since it lacks the abstraction properties provided by computer-aided drafting tools. This paper presents an integrated approach to geometric modeling...

The artifact ecologies emerging from the increasing number of interactive digital artifacts, capable of communicating with each other, have created a situation where software applications no longer need to be limited by the physical boundaries of a single artifact. In order to take advantage of the full potential of this situation, we first need to establish a common understanding of the intera...

While the fourth human visual field map (hV4) has been studied for two decades, there remain uncertainties about its spatial organization. In analyzing fMRI measurements designed to resolve these issues, we discovered a significant problem that afflicts measurements from ventral occipital cortex, and particularly measurements near hV4. In most hemispheres the fMRI hV4 data are contaminated by a...

BACKGROUND AND PURPOSE Metallic implants induce massive artifacts in CT images which deteriorate image quality and often superimpose structures of interest. The purpose of this study was to apply and evaluate a dedicated MAR method for neuroradiologic intracranial clips and detachable platinum coiling events. We here report the first clinical results for MAR in FDCT. MATERIALS AND METHODS FDC...
