Children with spina bifida meningomyelocele and hydrocephalus (SBM) have congenital dysmorphology of the midbrain and thinning of the posterior cortex, brain regions associated with the control of covert orienting. We studied cued covert orienting in 92 children with SBM, and 40 age-matched typically developing controls. Cues were of three types: exogenous (luminance change in a peripheral box ...

The homeland security has become a very significant consideration for all the Governments throughout the world. To improve the OPerational SECurity (OPSEC), multi relational graphs were introduced for Covert Network Analysis (CNA). In this paper, proposed SpyNetMiner system identifies the key players who maximally influence the covert network. Abnormality of the nodes is analyzed based on the p...

Covert channels are information leaks in systems that use resources to transfer secretly a message. They are a threat for security, performance, but also for a system’s profitability. This paper proposes a new approach to detect covert channels from scenario models of protocols. The problem of finding covert channels in scenarios is first modeled as a game, in which a pair of malicious users {S...

In this paper we argue for the existence of covert pied-piping in wh-questions through a previously unnoticed pattern of intervention effects in superiorityobeying English multiple wh-questions. We show that the preference of covert pied-piping is for movement of larger constituents, unlike overt pied-piping. We argue that this discrepancy stems from conflicting requirements of PF and LF: overt...

Using event-related fMRI, we analyzed the functional neuroanatomy of covert reorienting and inhibition of return (IOR). Covert reorienting to a target appearing within 250 msec after an invalid contralateral location cue elicited increased activation in the left fronto-polar cortex (LFPC), right anterior and left posterior middle frontal gyrus, and right cerebellum, areas that have previously b...

INTRODUCTION Among the functional neuroimaging studies on emotional face processing in schizophrenia, few have used paradigms with facial expressions of disgust. In this study, we investigated whether schizophrenia patients show less insula activation to macro-expressions (overt, clearly visible expressions) and micro-expressions (covert, very brief expressions) of disgust than healthy controls...

Several studies have suggested that covert stressors can contribute to bee colony declines. Here we provide a novel case study and show using radiofrequency identification tracking technology that covert deformed wing virus (DWV) infections in adult honeybee workers seriously impact long-term foraging and survival under natural foraging conditions. In particular, our experiments show that adult...

Several theorists have argued in favor of a distinction between overt and covert narcissism, and factor analytic studies have supported this distinction. In this paper I demonstrate that overt narcissists report higher self-esteem and higher satisfaction with life, whereas covert narcissists report lower self-esteem and lower satisfaction with life. I also present mediational models to explain ...

In this paper, I concern myself with the relationship of overt and covert Case to two types of word order in Korean; free vs. rigid word order. To characterize this relationship I will essentially assume the Attract-F theory in Chomsky 1995. I assume that (overt) Case markers are Ds with phonological features and Case features, and phonologically null (covert) Case markers also exist as their c...

We explore the use of real-time magnetic resonance imaging (rtMRI) as a tool to investigate apraxic speech, in particular, by examining articulatory behavior. Our pilot data reveal that covert (silent) gestural intrusion errors (employing an intrinsically simple 1:1 mode of coupling) are made more frequently by an apraxic subject than by fluent speakers. Covert intrusion errors are also found t...
