The concept of Erd} os number is well known among mathematicians and somewhat known more generally (see, for example, de Castro & Grossman, 1999] or the web site Paul Erd} os, who died in late 1996, was a mathematician who was author or coauthor|most often the latter|of nearly 1500 papers and had nearly 500 coauthors. By deenition, Erd} os had Erd} os number zero, his collaborators had Erd} os ...

OBJECTIVES To determine the clinical relevance of exudative retinal detachment (ERD) and the rate of ERD resolution after plaque radiotherapy of posterior uveal melanomas. METHODS Retrospective, nonrandomized study of 135 consecutive patients with posterior uveal melanoma treated by iodine 125 plaque radiotherapy. Extent of ERD and tumor thickness were assessed before radiotherapy and at post...

Electroencephalographic (EEG) event-related desynchronization (ERD) induced by movement imagery or by observing biological movements performed by someone else has recently been used extensively for brain-computer interface-based applications, such as applications used in stroke rehabilitation training and motor skill learning. However, the ERD responses induced by the movement imagery and obser...

OBJECTIVE Relation between cortical excitability and magnitudes of event-related dysynchronizaton (ERD) has not been clarified. This study was investigated that relationshp between cortical excitability and ERD magnitudes in healthy subjects and stroke patients. METHODS Ten healthy subjects and four patients with stroke participated in this study. EEGs were recorded over the sensorimotor cort...

BACKGROUND Lipid-lowering treatment with statins has proven to be effective in reducing cardiovascular events and mortality. In daily practice, however, adherence to medication is often low and this compromises the therapeutic effect. The aim of this study was to assess the effectiveness of an electronic reminder device (ERD) with or without counseling to improve refill adherence and persistenc...

BACKGROUND/AIMS Gastroesophageal reflux disease is one of the most common and frequent chronic disease requiring considerable cost. We investigated the medical care costs in the erosive reflux disease (ERD) and non-erosive reflux disease (NERD). METHODS The risk factors and the direct medical care costs were analyzed retrospectively in the ERD (178 patients) and NERD (183 patients) groups for...

exudative retinal detachment (erd) may be seen with many ocular pathologies including malignancies. among malignant causes, metastases of breast and lung carcinoma are most common. a 50-year-old woman referred to our clinic with history of decreased visual acuity in her right eye since 3 months before referral. the visual acuity was counting fingers at 2 meters and 6/10 in the right and left ey...

Objectives: To investigate the time resolution of different methods for the computation of event-related desynchronization/synchronization (ERD/ERS), including one based on Hilbert transform. Methods: In order to better understand the time resolution of ERD/ERS, which is a function of factors such as the exact computation method, the frequency under study, the number of trials, and the sampling...

The event-related desynchronization (ERD) is a magnitude decrease phenomenon which can be found in electroencephalogram (EEG) mu-rhythm in a certain narrow frequency band (reactive band) during different sensorimotor tasks and stimuli. The success of ERD detection depends on proper identification of subject specific reactive band. An adaptive algorithm band limited multiple Fourier linear combi...
