When grasping an object, subjects tend to look at the contact positions of the digits (A. M. Brouwer, V. H. Franz, D. Kerzel, & K. R. Gegenfurtner, 2005; R. S. Johansson, G. Westling, A. Bäckström, & J. R. Flanagan, 2001). However, these contact positions are not always visible due to occlusion. Subjects might look at occluded parts to determine the location of the contact positions based on ex...
3 Pattern recognition involves building a mental model to interpret incoming inputs. 4 This incoming information is often incomplete and the mental model must 5 extrapolate to complete the patterns, a process that is constrained by the statistical 6 regularities in nature. Examples of pattern completion involve identification of 7 objects presented under unfavorable luminance or interpretation ...
Newborn infants were familiarized to a three-dimensional display consisting of a rod which moved behind a central occluder, so that , only the top and bottom of the rod were visible. The infants’ eyes were 38 cm from the rod and the occluder was 15 cm in front of the rod, a separation intended to ensure that the gap between the two was detected by the infants. On subsequent test trials the infa...
BACKGROUND Our aim was to assess whether anterograde flow velocities in septal perforating branches could identify an occluded contralateral coronary artery, and to assess the feasibility and accuracy of diagnosing occlusions in the three main coronary arteries by the combined use of several noninvasive parameters indicating collateral flow. METHODS A total of 108 patients scheduled for coron...
OBJECTIVE To describe and compare the work of breathing (WOB) during spontaneous breathing under four conditions: (1) breathing through a tracheostomy tube with an inflated cuff, (2) breathing through the upper airway (UA) with a deflated cuff and occluded tube, (3) breathing through the UA with an occluded cuffless tube, and (4) postdecannulation. PATIENTS AND METHODS Patients who tolerated ...
PURPOSE The aim of this study is to investigate whether P wave dispersion (PWD), measured before, during and after fibrinolytic therapy (FT,) is able to predict successful reperfusion and infarct related artery (IRA) patency in patients with acute anterior MI who received FT. METHODS Sixty-eight patients who presented with acute anterior MI were enrolled in the study. An electrocardiogram was...
BACKGROUND Coronary artery bypass graft (CABG) surgery is the standard of care in the treatment of advanced coronary artery disease, and its long-term results are affected by the failure of bypass grafts. The aim of the present study was to evaluate the early patency rate in coronary bypass grafts. METHODS A total of 107 consecutive patients who underwent CABG were included in this study. Ear...
Left ventricular (LV) rupture potential was studied after transmural myocardial infarction (MI) in rabbits by measuring 1) the tensile strength of infarcted tissue strips, 2) the force required to initiate a tear (tear threshold) in the central infarcted region, and 3) the intracavitary pressure required to rupture the infarcted ventricle. During the first week after MI, infarcts resulting from...
Application of sewage sludge has been considered as an organic fertilizer in arid and semi-arid regions of Iran. This study was conducted to investigate cumulative and residual effects of sewage sludge on soil inorganic fractions and their relation to phosphorus (P) availability. Two levels of application (50 and 100 Mg ha-1) and three consecutive times of sewage sludge application (1, 3 and 5 ...
Object detections are critical technologies for the safety of pedestrians and drivers in autonomous vehicles. Above all, occluded pedestrian detection is still a challenging topic. We propose a new detection scheme for occluded pedestrian detection by means of lidar–radar sensor fusion. In the proposed method, the lidar and radar regions of interest (RoIs) have been selected based on the respec...
