Evaluation of the BOSS Online Submission and Assessment System
Computer programming lends itself to automated assessment. With appropriate software tools program correctness can be measured, along with an indication of quality according to a set of metrics. Furthermore, the regularity of program code allows plagiarism detection to be an integral part of the tools that support assessment. In this paper, we consider a submission and assessment system, called...

Introduction: Usually, when detecting activated regions in fMRI data, only the sequence of T2*-weighted images is analyzed. This image sequence contains blood oxygenation level dependent (BOLD) signal, which is related to neurological activity. Since the images are very noisy, spatial smoothing is applied before signal detection. To improve the detection performance, the filtering can be made a...

According to the original description by Rizzolatti and colleagues, the prerequisite of triggering the discharge of mirror neurons (MNs) is the interaction of the hand with an object. On the other hand, several studies reported that the MN system in humans can be activated also by non object-directed (intransitive) movements. This difference between human and monkey MN systems has been consider...

Despite overwhelming evidence that major depressive disorder (MDD) is heritable, intensive efforts to elucidate genetic variation underlying MDD have yielded only modest success, perhaps partly because genetic effects do not directly translate into dichotomous clinical phenotypes. Biomarkers, for instance measures of brain structure and function, may represent an intermediate step in the causal...

Abstract: The primary source of the BOLD fMRI contrast is the change in the oxygenation of blood due to mismatched changes in cerebral blood flow (CBF) and oxygen metabolism following neuronal activation. The CBF is regulated by dilation (and/or constriction) of cerebral vasculature in response to vasoactive mediators released from activated neurons and astrocytes. While a number of recent stud...
