In this paper, dynamic algorithm transformations (DAT’s) for designing low-power reconfigurable signal-processing systems are presented. These transformations minimize energy dissipation while maintaining a specified level of mean squared error or signal-to-noise ratio. This is achieved by modeling the nonstationarities in the input as temporal/spatial transitions between states in the input st...

statement of the problem early detection of periodontal disease and distruction is important for prevention of further destruction of the tissues. we carried out this study to determine the normal cement enamel junction (cej) to alveolar bone crest (abc) distance in the interproximal area of primary molars on bitewing (b. w) radiographs in healthy 7-9 year old girls living in hamadan, iran. mat...

INTRODUCTION In this study, we evaluated root and alveolar bone development in unilateral osseous impacted immature maxillary central incisors by cone-beam computed tomography before and after closed-eruption treatment, in comparison with naturally erupted contralateral immature maxillary central incisors. METHODS AND RESULTS The study included 30 patients, 20 boys and 10 girls, with a mean a...

This review details the invention and clinical testing of a new power toothbrush designed to provide a low cost, effective toothbrush, which has a combination of a round oscillating head in conjunction with fixed bristles. The data demonstrate this power toothbrush (Crest SpinBrush) is an effective cleaning toothbrush with respect to plaque removal. Four independent 4-period crossover studies, ...
