Hip arthroscopy has been popularized over the last decade and, with technical advances regarding imaging diagnostics, understanding of the physiopathology or surgical techniques, several applications have been described. Both arthroscopy for intra-articular conditions and endoscopy for extra-articular procedures can be used in diagnosing or treating different conditions. This updated article ha...

Relapsing fever Borrelia infections have attracted little attention in recent years; however, where endemic, these infections still result in considerable illness and death. Despite the marked antimicrobial drug susceptibility of these organisms, therapy is often delayed through lack of clinical suspicion. With increasing travel, infections may be imported, through exotic relapsing fever infect...

The rise of antibiotic-resistant bacterial strains, causing intractable infections, has resulted in an increased interest in phage therapy. Phage therapy preceded antibiotic treatment against bacterial infections and involves the use of bacteriophages, bacterial viruses, to fight bacteria. Virulent phages are abundant and have proven to be very effective in vitro, where they in most cases lyse ...

Keynes was writing in the midst of the Great Depression, but also as the results of the first two technology revolutions1 were being felt throughout society. Today, we are in the midst of the Third Technology Revolution 2 (TR3), which will do more than just increase productivity. It is likely to reduce the labor component of the maginal cost of production towards zero: In other words, TR3 is li...

This paper offers an improved model of the OASIS system, which is a distributed domain specific search system in the Internet. The main thrust of our approach is to connect OASIS servers with a high-speed network based on ATM technology. This high-speed network allows communication between servers. Here we present methods of connecting OASIS servers with the ATM network. Obtained results indica...

The patient's own attitude, activity and social interaction influence functional outcome and quality of life after stroke. Rehabilitation of stroke patients should start as soon as the patient is in a medically stable condition. The concept of early rehabilitation should be provided by an interdisciplinary team, preferably in stroke units. The key of successful rehabilitation is teamwork of the...

This paper concerns two related recent books by Nicholas Rescher, Imagining Irreality on possibilities and What If? on thought experiments—see [23] and [24]. The books are related because a theory on thought experiments presupposes a theory on possibilities. The effect of this and of the fact that they have a wider range of application than thought experiments will be that possibilities will re...

Understanding the prevalence of sexual reproduction in eukaryotes is a hard problem. At least two aspects still defy a fully satisfactory explanation, the functional significance of genetic recombination and the great variation among taxa in the relative lengths of the haploid and diploid phases in the sexual cycle. We have performed an experimental study to explore the specific advantages of h...

FOX (Free Objects for Xtallography) is a computer program for solving crystal structures of all types of compounds using the powder data (but also the single crystal data) measured using X-ray, neutron and electron diffraction. It works in direct space using the reversed Monte Carlo algorithm of global optimization. Since its release fifteen years ago, it has developed into a powerful tool, sim...

In this paper we analyze, mainly in a finitary setting, the consistency properties of fuzzy possibilities, interpreting them as instances of upper previsions and applying the basic notions of avoiding sure loss and coherence from the theory of imprecise probabilities. It ensues that fuzzy possibilities always avoid sure loss, but satisfy the stronger coherence condition only in a special case. ...
