We derive dynamic optimal trading strategies that minimize the expected cost of trading a large block of equity over a fixed time horizon. Specifically, given a fixed block SM of shares to be executed within a fixed finite number of periods 1, and given a price-impact function that yields the execution price of an individual trade as a function of the shares traded and market conditions, we obt...

Ectopic thyroid tissue (ETT) is a rare entity and a challenging differential diagnosis. This is a report of a case of a mediastinal mass that was found to be an ectopic mediastinal thyroid tissue, in a 77-year-old woman who was admitted to our hospital for breast cancer management. The mediastinal mass was identified in the postsurgical computed tomography (CT) scan of the chest and was suspect...

Advances in machine systems and scanning technologies have increased the use of selective laser melted materials industrial applications, resulting almost full-density products. Inconsistent mechanical behavior components under cyclic stress is caused by microstructure porosity created during powder melting. The extended finite element method, XFEM, was used to imitate crack propagation utilizi...
