International Mobile Telecommunications (IMT)Advanced is the new global standard defined by the International Telecommunication Union (ITU) for the fourth generation of mobile communication systems. Several technologies like Long Term Evolution (LTE)-Advanced have been proposed as IMT-Advanced candidates. In order to achieve this consideration, evaluations must ensure the achievement of a set o...

This paper provides an extension of Vuong’s (1989, Econometrica, 57, pp.307–333) model selection test to the multivariate case. We use the Kullback–Leibler Information Criterion (KLIC) to measure the closeness of a model to the truth to provide a diagnosis of many competing models where the models are not correctly specified. After investigating the asymptotic joint distribution of the likeliho...

BACKGROUND Most treatment of patients at risk for stroke is provided in the ambulatory setting. Although many studies have addressed the proportion of eligible patients with atrial fibrillation (AF) receiving warfarin sodium, few have addressed the quality of their anticoagulation management. OBJECTIVE As a comprehensive assessment of quality, we analyzed the proportion of eligible patients r...

BACKGROUND The aim of this study was to assess which patient and procedure factors affected both the risk of infection as well as procedure duration. Additionally, to assess if procedure duration affected the revision risk due to deep infection in total knee arthroplasty (TKA) patients and in a subgroup of low-risk patients. METHODS 28,262 primary TKA with 311 revisions due to deep infection ...

BACKGROUND AND PURPOSE It remains undetermined whether the use of coumarin anticoagulants associates with cerebral microbleeds in the general population. We investigated whether (1) coumarin use relates to higher prevalence and incidence of microbleeds, (2) microbleeds are more frequent in people with higher maximum international normalized ratios (INRs), and (3) among coumarin users, variabili...

BACKGROUND Warfarin is very effective in preventing recurrent venous thromboembolism but is also associated with a substantial risk of bleeding. After three months of conventional warfarin therapy, a lower dose of anticoagulant medication may result in less bleeding and still prevent recurrent venous thromboembolism. METHODS We conducted a randomized, double-blind study, in which 738 patients...

BACKGROUND In Thailand, risk factors associated with suicide attempts in bipolar disorder (BD) are rarely investigated, nor has a specific risk-scoring scheme to assist in the identification of BD patients at risk for attempting suicide been proposed. OBJECTIVE To develop a simple risk-scoring scheme to identify patients with BD who may be at risk for attempting suicide. METHODS Medical fil...

AIMS To compare the International Normalised Ratio (INR) obtained directly with the two types of WHO plain International Reference Preparation for thromboplastin in patients treated with coumarin. METHODS Prothrombin times were performed in parallel at four centres using WHO human plain IRP (BCT/253) and rabbit plain IRP (RBT/79). Sixty patients and 20 normal controls were tested at each cent...
