Objects with dynamic types allow the integration of operations that essentially require runtime type-checking into statically-typed languages. This article presents two extensions of the ML language with dynamics, based on our work on the CAML implementation of ML, and discusses their usefulness. The main novelty of this work is the combination of dynamics with polymorphism.

Although the term Big Data has become popular, there is no general consensus about what it really means. Often, many professional data analysts would imply the process of Extraction, Transformation and Load (ETL) for large datasets as the connotation of Big Data. A popular description of Big Data is based on three attributes of data: volume, velocity, and variety (or 3Vs). Nevertheless, it does...

we usewe use ml shear wave velocity to derive a high resolution 2d ml shear wave velocity map for the iranian plateau. the ml amplitudes and arrival times are routinely measured for the calculation of local magnitude. ml shear wave velocity is very sensitive to the lateral change of crustal thickness and switches between the velocity of lg and sn waves. an lg wave will die out as soon as encoun...

BACKGROUND Cervical interlaminar epidural injection (CIEI) is widely used in the management of acute or chronic neck and upper extremity pain. There is no consensus regarding the optimal volume of solution to be used for CIEI. STUDY DESIGN Randomized, double blind controlled trial. OBJECTIVE The purpose of this study was to evaluate how many spinal segments would be covered with different v...
