While it is widely acknowledged that the performance improvement in current biometrics-based personal authentication systems is necessary, it is not clear what mechanisms could be used to improve the performance. In this paper, we formulate the problem of multiple biometrics integration and examine whether the improvement in performance could be achieved(More)
Metformin and the thiazolidinediones (TZDs) may have a protective effect against the development of lung cancer. Patients with diabetes mellitus (DM) were identified from the electronic medical records of the Cleveland Clinic. Diabetics with lung cancer were identified then verified by direct review of their records. Control subjects were matched with(More)
BACKGROUND Failure to recruit a sufficient number of eligible subjects in a timely manner represents a major impediment to the success of clinical trials. Physician participation is vital to trial recruitment but is often limited. METHODS After 12 months of traditional recruitment to a clinical trial, we activated our electronic health record (EHR)-based(More)
Grouping images into (semantically) meaningful categories using low-level visual features is a challenging and important problem in content-based image retrieval. Based on these groupings, effective indices can be built for an image database. In this paper, we cast the image classification problem in a Bayesian framework. Specifically, we consider city vs.(More)
Clinical trials are essential to the progress of medical science. Physician participation in trial recruitment is vital, but most do not participate. Few approaches to improve physician participation in trial recruitment have been described or proven successful. Previously described approaches have largely relied on locally developed technology or been(More)
OBJECTIVE Sulfonylureas have historically been analyzed as a medication class, which may be inappropriate given the differences in properties inherent to the individual sulfonylureas (hypoglycemic risk, sulfonylurea receptor selectivity, and effects on myocardial ischemic preconditioning). The purpose of this study was to assess the relationship of(More)
BACKGROUND Physician participation in clinical research recruitment efforts is critical to many studies' success, but it is often limited. Use of an Electronic Health Record (EHR)-based, point-of-care Clinical Trial Alert (CTA) approach has led to significant increases in physician-generated recruitment and holds promise for wider benefit. However, little(More)
OBJECTIVE The objective of this study was to create a tool that predicts the risk of mortality in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS This study was based on a cohort of 33,067 patients with type 2 diabetes identified in the Cleveland Clinic electronic health record (EHR) who were initially prescribed a single oral hypoglycemic(More)
BACKGROUND Healthcare institutions spend enormous time and effort to train their workforce. Web-based training can potentially streamline this process. However the deployment of web-based training in a large-scale setting with a diverse healthcare workforce has not been evaluated. The aim of this study was to evaluate the satisfaction of healthcare(More)
Do parents' inaccurate beliefs about their children's academic skills distort investments in education? I analyze a field experiment conducted in Malawi and find that, at baseline, parents try to tailor their educational investments to their children's academic level, but their inaccurate beliefs prevent them from doing so. Providing parents with(More)
