[Duration of Dual Antiplatelet Therapy in Patients With Ischemic Heart Disease After Implantation of Endovascular Stents].

Optimal duration of dual antiplatelet therapy (DAPT) after stent implantation is uncertain. Some patients have an extended risk of thrombotic complications including that of very late stent thrombosis after cessation of recommended course of DAPT (6-12 months). On the other hand, there is a real risk of bleeding on DAPT.

Influence of Low-Frequency Vibration and Modification on Solidification and Mechanical Properties of Al-Si Casting Alloy.

One of the major aims of the modern materials foundry industry is the achievement of advanced mechanical properties of metals, especially of light non-ferrous alloys such as aluminum. Usually an alloying process is applied to obtain the required properties of aluminum alloys. However, the presented work describes an alternative approach through the application of vibration treatment, modification by ultrafine powder and a combination of these two methods.

PRec-I-DCM3: a parallel framework for fast and accurate large-scale phylogeny reconstruction.

Accurate reconstruction of phylogenetic trees often involves solving hard optimisation problems, particularly the Maximum Parsimony (MP) and Maximum Likelihood (ML) problems. Various heuristics yield good results for these problems within reasonable time only on small datasets. This is a major impediment for large-scale phylogeny reconstruction.
