PURPOSE Our recent study of three accelerometer brands in various ambulatory activities showed that the mean amplitude deviation (MAD) of the resultant acceleration signal performed best in separating different intensity levels and provided excellent agreement between the three devices. The objective of this study was to derive a regression model that estimates oxygen consumption (VO2) from MAD...

INTRODUCTION This study aimed to determine the effect of combining positive airway pressure (PAP) therapy and mandibular advancement device (MAD) in patients with severe obstructive sleep apnea (OSA) who were pressure intolerant for PAP and were unresponsive to MAD. METHODS This retrospective study reviewed the medical records of severe OSA patients with apnea-hypopnea index (AHI) ≥ 30/hr who...

OBJECTIVES To evaluate retrospectively the efficacy of the mandibular advancement device (MAD) in Korean patients with obstructive sleep apnea (OSA) in terms of severity and to evaluate prognostic factors deciding the success of MAD application. DESIGN Retrospective analysis. SETTING Academic tertiary referral center. PATIENTS Of 142 patients who underwent MAD application for OSA manageme...

Background: The usefulness of the modified Atkins diet (mAD) in refractory epilepsy in adults has been rarely investigated. We aimed to evaluate the efficacy of mAD in adult with refractory epilepsy. Methods: In a controlled randomized clinical trial, we enrolled 66 refractory adult epileptic cases from February 2010 to December 2012. The patients were randomly divided into two groups, case gro...

Adrenal function was assessed in control rats and in rats treated for 2 and 4 weeks with 17 alpha-methylandrostenediol (MAD; 17 alpha-methyl-5-androstene-3 beta-diol), a synthetic androgen known to produce hypertensive cardiovascular disease. In both groups and at both time periods, a circadian rhythm of blood corticosteroid concentrations was observed. The high point for serum corticosterone (...

In the present work we introduce a new are activity indicator, MAD and examine its characteristics by analyzing a set of successive three days' observations of a typical active region, AR2372. The computed MAD is compared with conventional activity indicator such as separator. It is found that (1) MAD traces very well the separator, (2) it singles out local discontinuity of magnetic eld lines a...

This paper introduces the multivariate alteration detection (MAD) transformation which is based on the established canonical correlation analysis. The MAD transformation is invariant to linear scaling. It is therefore insensitive to for example differences in gain settings in a measuring device. Other multivariate change detection schemes described are principal component type analysis of simpl...

— A correct radiometric normalization between both images is fundamental for change detection. MAD method and its IR-MAD extension in an implementation on multisprectral aerial images is described in this paper.
