Bertrand’s Paradox Revisited: More Lessons about that Ambiguous Word, Random

The Bertrand paradox question is: “Consider a unit-radius circle for which the length of a side of an inscribed equilateral triangle equals 3 . Determine the probability that the length of a ‘random’ chord of a unit-radius circle has length greater than 3 .” Bertrand derived three different ‘correct’ answers, the correctness depending on interpretation of the word, random. Here we employ geomet...

More about measures and Jacobians of singular random matrices

In this work are studied the Jacobians of certain singular transformations and the corresponding measures which support the jacobian computations.

Being more positive about negative ventilation?

Mechanical ventilation is undoubtedly a lifesaving procedure for patients with acute respiratory failure [1]. Unfortunately the procedure is also associated with a number of unwanted side-effects. Firstly, until recently, mechanical ventilation required endotracheal intubation either through a tracheostomy or with a translaryngeal tube, procedures which can carry some risks [2, 3]. Secondly, by...
