Real-time garbage collection is essential if object-oriented languages (in particular, Java) are to become predictable enough for real-time embedded systems. Although techniques for hard real-time garbage collection exist, they are based on estimations of the maximum amount of referenced (live) memory. Such estimations may be difficult to derive manually for complex programs.We present techniques

Arterial cardiovascular disease and neighborhood deprivation are associated. However, no study has determined whether neighborhood deprivation is associated with venous thromboembolism (VTE). We aimed to determine whether there is an association between neighborhood deprivation and hospitalization for VTE, and whether effects vary across sociodemographic groups. The entire Swedish population aged

Spectrum balancing (SB) techniques optimize transmission and can significantly improve digital subscriber lines (DSL) services. In the literature, the DSL system optimization is typically formulated as a rate maximization problem. However, there is an increasing interest in minimizing the considerable amount of power consumed by telecommunication networks. Few works in the SB literature have explo

We develop an approximation for the optical potential in a solid, valid at intermediate energies, i.e. energies greater than 50 eV. The present approximation for the optical potential builds on the GW-expression. We separate the RPA polarization propagator into a core electron and a valence electron, and can then achieve a corresponding separation of the optical potential. We apply this method to

Substituted aminomethylphenol dyes, low-molecular-mass isoelectric point (pI ) markers and hemoglobin samples from normal individuals and diabetic patients were used to test a new set-up of capillary isoelectric focusing (cIEF) in uncoated capillaries. In previous cIEF methods, a mixture of sample components and carrier ampholytes was applied in the capillary and analyzed. In the new set-up a frac

Various biological problems such as disease mechanisms, drug development and toxicological studies motivated the introduction of cellular models that today also represent an alternative for reducing the use of animals in controversial medical and pharmaceutical experiments. Cells are complex matrices where several processes occur simultaneously. Because of this, analytical methods with specific p

The borderless world is providing new opportunities for conducting business, both within Europe and between continents. Sustainable competition will be harder to attain and competition will become fiercer, day-by-day. The Austrian school of strategy emphasizes change, continuous innovation, and entrepreneurial discovery as sources of supernormal profits. An important assumption is that these super
