This paper considers the problem of monitoring vehicle data streams in a resource-constrained environment. It particularly focuses on a monitoring task that requires frequent computation of correlation matrices using lightweight on-board computing devices. It motivates this problem in the context of the Mine-Fleet Real-Time system and offers a randomized(More)
We explored the effect of unilateral intracarotid sodium amobarbital injection during the Wada test (intra-arterial amobarbital procedure, IAP) on functional connectivity in the brain assessed by synchronization analysis of the EEG. Patients suffering from pharmaco-resistant epilepsy who were selected for epilepsy surgery and underwent a preoperative IAP to(More)
For bounded datasets such as the TREC Web Track the computation of term frequency (TF) and inverse document frequency (IDF) is not difficult. However, since IDF cannot be directly calculated for the entire web, it must be estimated. We see a need to estimate accurate IDF values to generate TF-IDF based lexical signatures (LSs) of web pages. Future(More)
OBJECTIVE This study was undertaken to test the hypothesis that brain tumors interfere with normal brain function by disrupting functional connectivity of brain networks. METHODS Functional connectivity was assessed by computing the synchronization likelihood in a broad band (0.5-60Hz) or in the gamma band (30-60Hz) between all pairwise combinations of(More)
INTRODUCTION Alzheimer's disease (AD) usually first presents in elderly patients, but may also develop at an earlier age. Patients with an early age at onset tend to present with complaints other than memory impairment, such as visuospatial problems or apraxia, which may reflect a different distribution of cortical involvement. In this study we set out to(More)
We investigated the mechanisms underlying neurocognitive dysfunction in patients with low-grade glioma (LGG) by relating functional connectivity revealed by magnetoencephalography to neurocognitive function. We administered a battery of standardized neurocognitive tests measuring six neurocognitive domains to a group of 17 LGG patients and 17 healthy(More)
PURPOSE Patients with gliomas often experience cognitive deficits, including problems with attention and memory. This randomized, controlled trial evaluated the effects of a multifaceted cognitive rehabilitation program (CRP) on cognitive functioning and selected quality-of-life domains in patients with gliomas. PATIENTS AND METHODS One hundred forty(More)
Widespread disturbances in resting state functional connectivity between remote brain areas have been demonstrated in patients with brain tumors. Functional connectivity has been associated with neurocognitive deficits in these patients. Thus far, it is unknown how (surgical) treatment affects functional connectivity. Functional connectivity before and(More)
