A race condition is a situation where two threads manipulate a data structure simultaneously, without synchronization. Race conditions are common errors in multithreaded programming. They often lead to unintended nondeterminism and wrong results. Moreover, they are notoriously hard to diagnose, and attempts to eliminate them can introduce deadlocks. In practice, race conditions and deadlocks ar...

Background:The diagnostic accuracy of frozen section as an important source of information in surgical pathology is important not only in the management of surgical patients but also as a measure of quality control in surgical pathology. In this study, we evaluated the diagnostic accuracy of frozen sections over a 6-year period in a teaching hospital in Iran. Methods: We retr...

The finite element method is employed for the flexural-torsional linear buckling analysis of beams of arbitrarily shaped composite cross-section taking into account generalized warping (shear lag effects due to both flexure and torsion). The contacting materials, that constitute the composite cross section, may include a finite number of holes. A compressive axial load is applied to the beam. The...

The first section gives the measure of uncertainty given by Shannon (1948) and the generalizations thereof by Schvitzenberger (1954), Kullback (1959), Renyi (1961,1965), Kapur (1967, 1968), and Rathie (1970). It gives some postulates characterizing Shannon's entropy, Renyi's entropy of order a and our entropy of order a and type P. It also gives some properties of this most general type of entr...

A Look at Contemporary Persian Poetry, Currents in Persian Poetry in 20th Century This book is a historical survey of literature though the writer has tried to distance himself from ancient approaches and to apply a modern look of analysis, critique and stylistics. In the first chapter the methodology is discussed followed by the second chapter which talks of text and metatext and the relation...

Two families of q-Schur algebras associated to Hecke algebras of type D are introduced, and related to a family used by Geck, Gruber and Hiss [10], [11]. We prove that the algebras in one family, called the q-Schur algebras, are integrally free, stable under base change, and are standardly stratified if the base field has odd characteristic. In the so-called linear prime case of [10],[11], all ...

herein, we reported on a case of solid type of pulmonary actinomycosis in a 10-year-old boy. he had productive cough for 40 days. bronchoscopy was normal. cmputed tomography revealed a solid large mass in the upper lobe of his left lung with mimicking malignant leisions. he was referred for surgery and underwent left upper lobectomy. macroscopically, the specimen measured 13×9×5 cm and was crea...
