We investigated the perceived locations of two stimuli flashed successively near the time of saccade execution in a dark room. The inter-stimulus interval (ISI) between the flashes ranged from 80 to 240 ms. The results show that when the ISI was 120 ms or shorter, perceived locations of the flashes interacted with each other so that the perceived distance between them was equal to the distance ...

We investigated the extent of hemodynamic recovery following the paired presentation of either identical or different faces at two different inter-stimulus intervals (ISI). Signal recovery was consistently better at an ISI of 6 sec compared to 3 sec. Significantly less signal recovery was associated with identical faces compared to different faces in bilateral mid-fusiform and right prefrontal ...

With the vast amount of accessible, online content, it is not surprising that unscrupulous entities “borrow” from the web to provide filler for advertisements, link farms, and spam and make a quick profit. Our insight is that cryptographic hashing and fingerprinting can efficiently identify content reuse for web-size corpora. We develop two related algorithms, one to automatically discover prev...

Background: The International Sensitivity Index (ISI) calibration of whole-blood prothrombin time (PT) monitors for point-of-care testing (POCT) described by Tripodi et al. (Thromb Haemost 1993;70:921–4) has been shown to be dependable but is too complex and demanding. The use of plasma would simplify calibration of whole-blood POCT PT monitors, but important differences may exist between the I...

background citation analysis as one of the most widely used methods of bibliometrics can be used for computing the various impact measures for scholars based on data from citation databases. journal citation reports (jcr) from thomson reuters provides annual report in the form of impact factor (if) for each journal. objectives we aimed to evaluate the citation parameters of hepatitis monthly by...

Schizophrenia is associated with a deficit in working memory, with the degree of working memory impairment related to the level of social and occupational functioning. This study tests the hypothesis that the working memory deficits in individuals with schizophrenia can be explained by slow processing of visual stimuli, as measured by the attentional blink (AB) task. Individuals with schizophre...

STUDY DESIGN A prospective imaging study to develop diagnostic criteria. OBJECTIVE The aim of this study was to investigate image findings on delayed magnetic resonance imaging (MRI) after the acute phase of spinal cord injury without radiographic abnormality (SCIWORA) and their relationship with symptom severity. SUMMARY OF BACKGROUND DATA MRI is used to diagnose acute neurological injury,...

CONTEXT Insulin resistance is associated with altered vascular function in diabetes. OBJECTIVE The objective of the study was to define the overall and regional aortic function as well as the changes of aortic function over time in nondiabetic individuals with insulin resistance and a normal oral glucose tolerance test (OGTT). DESIGN This was a cross-sectional and longitudinal analysis with...

Information systems infrastructure (ISI) was ranked as the most important issue in a 1994-1995 study of key issues in IS management (Brancheau et al. 1996). Yet, to date, little theoretical and empirical work has been done in this area. This study attempts to reconceptualize the ISI construct and its measures. Drawing from the literature, this study envisions ISI as a base of shared technologic...
