We consider multi-receiver networks with diversity reception from an information-theoretic point of view. In particular we nd their capacity and investigate how the frequency spectrum should be allocated to the users. We conclude that eecient transmission schemes cannot be built based on re-use partitioning and therefore advocate a spread spectrum approach.(More)
BACKGROUND The complexity of surgical interventions has major implications for the design of RCTs. Trials need to consider how and whether to standardize interventions so that, if successful, they can be implemented in practice. Although guidance exists for standardizing non-pharmaceutical interventions in RCTs, their application to surgery is unclear. This(More)
BACKGROUND Deep venous thrombosis (DVT) and pulmonary embolism (PE) are recognized as major causes of morbidity and mortality in orthopaedic trauma patients. Despite the high incidence of these complications following orthopaedic trauma, there is a paucity of literature investigating the clinical risk factors for DVT in this specific population. As our(More)
The problem attempted in this paper is to select a sample from a large set where the sample is required to have a particular average property. The problem can be expressed as an optimisation problem where one selects a subset of <i>r</i> objects from a group of <i>n</i> objects and the objective function is the mismatch between the required average property(More)
