INTRODUCTION Whereas the efficacy of cognitive-behavioural therapy has been demonstrated for a variety of mental disorders, there is still need for improvement, especially regarding less prevalent or more severe disorders. Recently, metacognitive interventions have been developed and are now available for a variety of diagnoses. Still, a systematic review investigating the effectiveness of diff...

Family caregivers provide uncompensated care and assistance to a family member who has cancer. When patients move through the care trajectory into the survivorship phase, roles and demands of caregivers change and caregivers assume responsibility to assist with coordination of ongoing care. The goal of this article is to describe aspects of caregiver experiences and the roles of caregivers as p...

Osteoarthritis (OA) involves changes in the composition and ultimately the loss of cartilage from articulating joints. MRI has the ability to non-invasively probe the compositional integrity of cartilage, thereby potentially identifying diseased cartilage before loss occurs. In this study we have developed a technique to compare local changes in signal intensity over time in fat suppressed 3D g...

Using the Portuguese interactive television service from TV Cabo as a working basis, this paper discusses the potential of communication services such as chat, forums and multi-user games to act as iTV community builders and to become real iTV killer applications. In the three cases presented in this paper – multi-player iTV games, interactive football matches and iTV talk-show “Noites Interact...

We consider a mechanical system which is controlled by means of moving constraints. Namely, we assume that some of the coordinates can be directly assigned as functions of time by implementing frictionless constraints. This leads to a system of ODE’s whose right hand side depends quadratically on the time derivative of the control. In this paper we introduce a simplified dynamics, described by ...

Active Galactic Nuclei (AGN) play an important role in many aspects of the modern cosmology, and of particular interest is the issue of the interplay between AGN and their host galaxy. Using X–ray and optical data sets, we have explored the properties of a large sample of AGNs in the Subaru/XMM-Newton Deep Survey (SXDS) field, and studied their evolution in relation with the evolution of their ...

State constrained optimal control problems represent severe analytical and numerical challenges. A numerical algorithm based on an active set strategy involving primal as well as dual variables, suggested by a generalized Moreau-Yosida regularization of the state constraint is proposed and analyzed. Numerical examples are included.

INTRODUCTION The purpose of this study was to evaluate the long-term stability of quad-helix/crib treatment in subjects with dentoskeletal open bite. METHODS Twenty-eight subjects (11 boys, 17 girls; mean age, 8.2 ± 1.3 years) were treated consecutively with quad-helix/crib appliances. The patients were reevaluated at the end of active treatment with the quad-helix/crib (mean age, 9.7 ± 1.6 y...

MANY patients in mental hospitals, while no longer needing the active treatment services of a hospital, are still unable to live in the community without help. In addition, there are many patients in the community for whom hospitalisation is not yet necessary but for whom some form of help is needed to prevent it in the near future. Voluntary and governmental groups have long been aware of the ...

IT is now widely accepted that subnormal patients who do not require hospital services should not be in hospital but should be in hostel-type accommodation under educational and welfare authorities if they cannot be cared for in their own homes. However, the application of this policy to patients already in hospital presents difficulties, both because there are differences of opinion about the ...
