BACKGROUND AND PURPOSE Absence of the MCA susceptibility vessel sign (negative MCA susceptibility vessel sign) on gradient recalled-echo MR imaging in acute stroke is commonly associated with in situ stenosis and thrombotic occlusion. We evaluated the effectiveness and safety of the Solitaire stent as the first-line device for the recanalization of MCA occlusion with a negative MCA susceptibili...

Within both game studies and development communities, it is often argued that a game’s processes (rules and goals) are of primary significance when considering a game’s meaning. In opposition to this position, some claim that this approach denies player subjectivity by ignoring the dynamic, culturally-embedded ways in which players create, rather than receive, meaning through play. This paper c...

Long term defence planning is a complex undertaking involving many separate analytical steps and with non-trivial transitions from one step to the next. Many nations struggle with the challenge of establishing analytical rigour, structure and traceability in their defence planning processes. In this paper we will present a tool that has been developed not only to support defence planning, but w...

The Central Computing services at the Universiteit van Amsterdam (UvA) [17] have deployed an instance of the JASIG Uportal [18] system for use by a student audience of around 22,000. To achieve the requirement of a homogenous experience for the end user required a transition to a more consistent and unified Single Sign-On (SSO) and Single Sign-Off interaction with the underlying diverse infrast...

Traffic sign detection is extremely important in autonomous driving and transportation safety systems. However, the accurate of traffic signs remains challenging, especially under extreme conditions. This paper proposes a novel model called Sign Yolo (TS-Yolo) based on convolutional neural network to improve recognition accuracy signs, low visibility restricted vision A copy-and-paste data augm...

we give further results for perron-frobenius theory on the numericalrange of real matrices and some other results generalized from nonnegative matricesto real matrices. we indicate two techniques for establishing the main theorem ofperron and frobenius on the numerical range. in the rst method, we use acorresponding version of wielandt's lemma. the second technique involves graphtheory.

Failures of the vehicle camera may compromise correct acquisition frames, that are subsequently used by autonomous driving tasks. A clear understanding behavior tasks under such failure conditions, together with strategies to avoid safety is jeopardized, indeed necessary. This study analyses and improve performance Traffic Sign Recognition (TSR) systems for road vehicles possible occurrence fai...

Editorials on a CT slice. Using 10 mm thick CT slices, the diagnostic yield from fiberoptic bronchoscopic procedures (FOB) was 60 percent for SPNs with the positive bronchus sign, and 30 percent for SPNs without this sign. Some SPNs were also scanned using 1.5 mm thick slices (thin-section CT), and the diagnostic yield of SPN without the positive bronchus sign dropped from 30 to 14 percent. Thi...
