The calculation of natural frequencies of rods and beams with stiffness boundaries is a common problem encountered by vibration engineers. For linear springs attached to the boundaries, this is a straightforward problem, ...

In the current issue of the Journal, Caso Mae-stro et al. (1) describe their experience using abiological mesh for delayed abdominal wall clo-sure after pediatric liver transplantation. Theauthors should be congratulated ...

In two dimensions there are optimal bounds for the effective conductivity of arbitrary mixtures of two heat conducting materials: one isotropic and the other anisotropic; used in fixed volume fractions and allowing for ...

Moment-closure approximations are an important tool in the analysis of the dynamics on both static and adaptive networks. Here, we provide a broad survey over different approximation schemes by applying each of them to the ...

Quantum computing is an emerging technology with great potential: while quantum computers can solve certain computational problems with a exponentially gain of time in relation of the classical computers implementations, ...

The morphology and hydrodynamic conditions to which a beach is exposed are important for solving many of the problems faced by coastal management (protection and/or regeneration of the coasts). Monitoring and modelling of ...
