Carbon nanotube field-effect transistors (CNFETs) are a promising candidate to replace conventional metal oxide field-effect transistors (MOSFETs) in the time to come. They have considerable characteristics such as low power consumption and high switching speed. Full adder cell is the main part of the most digital systems as it is building block of subtracter, multiplier, compressor, and other ...

Low sensitivity of film-screen mammography in women aged 40 to 49 years paved the way for digital mammography (1), which improves screening sensitivity relative to film-screen mammog-raphy in women with dense breasts, pre-and perimenopausal women, and those aged 40 to 49 years (2,3). Digital mammog-raphy now accounts for 94% of mammography units in the U.S. (4). New evidence reported in this is...

This paper presents an ontology-based annotation system and BI-RADS (Breast Imaging Reporting and Data System) score reasoning with Semantic Web technologies in mammography. The annotation system is based on the Mammography Annotation Ontology (MAO) where the BI-RADS score reasoning works. However, ontologies are based on crisp logic and they cannot handle uncertainty. Consequently, we propose ...

Abstract Background Tomosynthesis is a recent advancement of full-field digital mammography involves transforming two-dimensional (2D) breast images into three dimensions (3D) images. It reduces the adverse effect tissue superimposition on conventional 2D- mammography, therefore having high potential enhancing identification and assessment asymmetric densities. The aim study was to assess compa...

Contrast-detail experiments were performed to optimize technique factors for the detection of low-contrast lesions using a silicon diode array full-field digital mammography (FFDM) system under the conditions of a matched average glandular dose (AGD) for different techniques. Optimization was performed for compressed breast thickness from 2 to 8 cm. FFDM results were compared to screen-film mam...
