I. Introduction Until recently, an understanding of the range of scales of turbulent flow and its dynamic interaction with the performance and wake characteristics of axial-flow marine hydrokinetic turbines was lacking. Advancing this area of knowledge within the field of marine and hydrokinetic energy research, development, and deployment will lead to more efficient turbine operations and redu...

Introduction : Infective endocarditis is a serious infection of the heart endothelium and valves. It carries long-term health risks and compromises the heart condition. However, this condition has been rarely observed since the introduction of appropriate antibiotic prophylaxis. Dentists play a major role in preventing infective endocarditis in susceptible patients. In this study, we assessed t...

Objective: The safest method for a reliable registration on the lateral skull base is the placement of fiducial markers into the patient’s bone by screws. An alternative method is the use of a resin splint that is fixated to the maxillary dentition, which carries the fiducial markers. Then the invasive fixation using bone screws becomes unnecessary. The aim of this study was to evaluate the acc...

When numbers are added in base b in the usual way, carries occur. If two random, independent 1-digit numbers are added, then the probability of a carry is b−1 2b . Other choices of digits lead to less carries. In particular, if for odd b we use the digits {−(b− 1)/2,−(b− 3)/2, . . . , . . . (b− 1)/2} then the probability of carry is only b −1 4b2 . Diaconis, Shao and Soundararajan conjectured t...
