This report presents different approaches to solving sparse linear systems—direct and iterative solvers—and compares a number of methods in each category. I also consider the two techniques of using solvers for linear systems: single method solver schemes and multi-method solver schemes. I also present some of the popular systems that use these techniques. This involves surveying the relevant l...

Many years ago, longer than I may care to admit, I had to take my Board Exam in Pulmonary Medicine. I decided to prepare for the exam by reading a reference textbook cover-to-cover. Because Dr Gerald Baum had been one of my favorite teachers while I was a medical student in Cleveland, I naturally felt inclined towards an earlier edition of Baum’s Textbook of Pulmonary Medicine. It was a most fo...

Pulmonary arterial hypertension (PAH) is characterized by elevated pulmonary artery (PA) pressure, which negatively affects the right ventricular (RV) function. This report shows a patient with severe PAH, on whom a comprehensive MRI exam was performed to evaluate both PA and RV. New imaging sequences were implemented for obtaining additional parameters about the patient's condition. The result...

Introduction. Total exam in medical basic sciences as an authorization for entering to the next level is held every year. To assess the statistical results of total medical basic science exam. Methods. The statistical results of 12th to 24th basic sciences comprehensive exam were studied through a descriptive and applied project. The grade, average and the percentage of answering to the questi...

BACKGROUND AND OBJECTIVES The testicular exam was not explicitly taught at our medical schools before 2002. In this article, we explore different phases of curriculum development, implementation, and evaluation of a method for teaching the testicular exam. METHODS Medical students participated in surveys and focus groups, and male patients participated in focus groups. From the results of the...

PURPOSE Medical students are traditionally taught the physical exam as a comprehensive battery of maneuvers, yet they express uncertainty about which maneuvers are "core" and should be performed routinely on patients and which ones should be performed only when clinically indicated. The authors sought to determine whether educator consensus existed on the concept and the specifics of a core phy...

PURPOSE An objective tool is desired, which optimally prepares for Radiology boards examination. Such program should prepare examinees with pertinent radiological contents and simulations as expected in the real examination. BACKGROUND Many countries require written boards examinations for Radiology certification eligibility. No objective measure exists to tell if the examinee is ready to pas...
