Algebraic multigrid (AMG) is an efficient multilevel method for solving large sparse linear systems obtained from the discretisation of scalar elliptic partial differential equations. AMG can be used to compute powerful preconditioners for use with Krylov subspace methods. We report on the design and development of an efficient, robust and portable implementation of AMG that is available as pac...

A k-rainbow path in a graph with colored edges is a path of length k where each edge has a different color. In this note, we settle the problem of obtaining a constructive k-coloring of the edges of Kn in which one may find, between any pair of vertices, a large number of internally disjoint krainbow paths. In fact, our construction obtains the largest possible number of paths. This problem was...

A new approach to indexing a specialized database by utilizing the color and spatial domain knowledge available for the database is described. This approach is illustrated by using it to provide a solution to the problem of indexing images of flowers for searching a flower patents database by color. The flower region is isolated from the background by using an automatic iterative segmentation a...

Abstract Aim In recent years, numerous minimally invasive techniques have been developed for the repair of midline hernias associated with diastasis recti. The eMILOS technique (Endoscopic mini/less open sublay technique) allows mesh placement in retromuscular space through a small trans-hernial incision without entering abdominal cavity. Material & Methods We present case 45 year-old male ...

Introduction Mevalonate kinase deficiency (MKD) has a wide spectrum and severity of clinical manifestation. Patients with mutations in MVK gene leading to complete lack of the enzyme, suffer from the most severe form of disease, also known as mevalonic acydosis, whereas defects with preserved, but insufficient enzyme activity present with autoinflammatory syndrome , also known as hiperIgD syndr...
