Background: Two questions about diagnostic value of urinary neutrophil gelatin associated lipocalin (uNGAL) in detection of acute kidney injury (AKI) in children have remained unanswered; first, which cut-off point of uNGAL has the highest value in detection of AKI; and second when is the best time for measuring this biomarker in a patient? Accordingly, the present study aimed to conduct a syst...

Gastpar and Vetterli named the ad-hoc networks with one randomly selected source-destination pair as relay networks and they suggested using arbitrary network coding in order to increase the overall efficiency Here, the relay network is investigated with two relays and no interference and a new achievable rate is obtained using a new network coding (decode-and-broadcast). The obtained achievabl...

We present a segmentation method for 3D point clouds, resulting from a stereo camera. Given an unsorted list of points the algorithm splits the data recursively until some quality level is achieved. In the second and the last step we use a mincut method in order to summarize similar plane-clusters from a global point of view. The method does not require any prior knowledge about the scene and w...

Measuring sedentary behaviour and physical activity with wearable sensors provides detailed information on activity patterns and can serve health interventions. At the basis of activity analysis stands the ability to distinguish sedentary from active time. As there is no consensus regarding the optimal cut-point for classifying sedentary behaviour, we studied the consequences of using different...

BACKGROUND The Actionable questionnaire is an 8-item tool to screen patients with multiple sclerosis (MS) for neurogenic bladder problems, identifying those patients who might benefit from urological referral and bladder-specific treatment. The original scoring yields a total score of 0 to 24 with cut-off point 6. A simplified scoring, yielding a total score of 0 to 8 with cut-off point 3, has ...
