Background: Good compliance in chronic obstructive pulmonary disease (COPD) is of 'paramount importance' in reducing the occurrence of acute exacerbations, hospitalisation and mortality and in improving quality of life. However, a number of studies have confirmed that long-term compliance is low and often associated with difficulties in handling maintenance inhalers. Therefore, the easier an inhaler is to use, the more likely the patient will comply with handling instructions and so, optimise control of the condition. Read More

Objectives: Global concern around over the counter availability of codeine containing products and risk of misuse, dependence and related harms are evident. A phenomenological study of lived experiences of codeine misuse and dependence was undertaken in Ireland, following the Pharmaceutical Society of Ireland's 2010 guidelines for restricted supply of non-prescription codeine containing products.
Methods: In-depth interviews were conducted with a purposive sample of adult codeine misusers and dependents (n=21), both actively using, in treatment and in recovery. Read More

Experimentally derived, amino acid specific backbone dihedral angle distributions are invaluable for modeling data-driven conformational equilibria of proteins and for enabling quantitative assessments of the accuracies of molecular mechanics forcefields. The protein coil library that is extracted from analysis of high-resolution structures of proteins, has served as a useful proxy for quantifying intrinsic and context-dependent conformational distributions of amino acids. However, data that go into coil libraries will have hidden biases, and ad hoc procedures must be used to remove these biases. Read More

It is well known that the classical exploratory factor analysis (EFA) of data with more observations than variables has several types of indeterminacy. We study the factor indeterminacy and show some new aspects of this problem by considering EFA as a specific data matrix decomposition. We adopt a new approach to the EFA estimation and achieve a new characterization of the factor indeterminacy problem. Read More

It is widely accepted that optimization of imaging system performance should be guided by task-based measures of image quality (IQ). It has been advocated that imaging hardware or data-acquisition designs should be optimized by use of an ideal observer (IO) that exploits full statistical knowledge of the measurement noise and class of objects to be imaged, without consideration of the reconstruction method. In practice, accurate and tractable models of the complete object statistics are often difficult to determine. Read More

Edged weapons (sometimes referred to as sharp weapons or blades) are an increasing threat to military personnel, the blue light community (police, ambulance, firefighters, other first responders) and the general public worldwide. The use of edged weapons in criminal and terrorist incidents internationally means the forensic community needs an awareness of the technology of edged weapons, how they are used, the damage (clothing and wounding) that might be caused and any other forensic implications. In this paper, the magnitude of the problem is presented, prior research summarised and implications for forensic investigations discussed. Read More

Amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's disease, is a progressive and fatal neuromuscular disease; the majority of ALS patients die within 2-5 years of receiving a diagnosis (1). Familial ALS, a hereditary form of the disease, accounts for 5%-10% of cases, whereas the remaining cases have no clearly defined etiology (1). ALS affects persons of all races and ethnicities; however, whites, males, non-Hispanics, persons aged ≥60 years, and those with a family history of ALS are more likely to develop the disease (2).
