In the general form of multiprocessor precedence scheduling problems a set of n tasks to be executed on m processors is given. Each task requires exactly one unit of execution time and can run on any processor. A directed acyclic graph specifies the precedence constraints where an edge from task x to task y means task x must be completed before task y begins. A solution to the problem is a sche...

PURPOSE To prospectively investigate the factors--including subject, brain hemisphere, study site, field strength, imaging unit vendor, imaging run, and examination visit--affecting the reproducibility of functional magnetic resonance (MR) imaging activations based on a repeated sensory-motor (SM) task. MATERIALS AND METHODS The institutional review boards of all participating sites approved ...

During the last several years many authors have found that the European System for Cardiac Operative Risk Evaluation is useful in the prediction of not only postoperative mortality but also of the length of stay in the intensive care unit, complication rate and overall treatment expenses. This study included 329 patients who had undergone isolated surgical myocardial revascularization at our De...

In order to increase gross harvest and productivity of rice, the development new varieties their timely use in production is great importance. The Federal Research Center Rice Agricultural “Donskoy” regularly develop more productive with improved resistance diseases other factors. Each variety forms a specific response various agro-ecological conditions, which affects productivity, main indicat...

PURPOSE To evaluate the morphological changes in retinal microstructures following modified photodynamic therapy (PDT) for chronic central serous chorioretinopathy. SUBJECTS AND METHODS Retrospective study of 21 consecutive eyes (age, 59±8.0 years [mean ± SD]) of 21 patients with chronic central serous chorioretinopathy. Inner foveal thickness (the distance between the internal limiting membr...

introdouction: canal length measurement is essential for proper endodontic treatment. any error or miscalculation in working length determination, particularly in curved canals, can result in complications during or after root canal therapy. digital radiography has enabled accurate measurement of curved canal length. in this study, we evaluated the accuracy of calibration of a complementary met...

In this paper, we study the following detection problem. There are n detectors randomly placed in the unit square S = [ − 2 , 12 2 assigned to detect the presence of a source located at the origin. Time is divided into slots of unit length and Di(t) ∈ {0, 1} represents the (random) decision of the ith detector in time slot t. The location of the source is unknown to the detectors and the goal i...
