BACKGROUND Digital breast tomosynthesis with 3D images might overcome some of the limitations of conventional 2D mammography for detection of breast cancer. We investigated the effect of integrated 2D and 3D mammography in population breast-cancer screening. METHODS Screening with Tomosynthesis OR standard Mammography (STORM) was a prospective comparative study. We recruited asymptomatic wome...
The uptake of digital photos vs. print photos has altered the practice of photo-sharing. Print photos are easy to share within the home, but much harder to share outside of it. The opposite is true of digital photos. People easily share digital photos outside the home, e.g., to family and friends by e-mail gift-giving, and to social networks and the broader public by web publishing. Yet within ...
in this paper, a new propagation model based on utd for multiple diffraction paths in cellular mobile radio communications in urban environments is proposed. moreover, the most rigorous novel utd-based expressions for multiple diffractions by buildings and excess path losses are d - rived and analyzed. for this purpose, building rows are supposed to have rectangular cross-sections with the same...
The affordability of plasma screens and high-speed Internet access has led to the proliferation of digital signage in public and private commercial locations over the past years. Marketers, content strategists and technologists have increasingly tried to capture the attention of consumers using digital signage, and this has led to rapid advances in the technology. Consumers, however, might be e...
The application of forward genetic screens to cultured human cells represents a powerful method to study gene function. The repurposing of the bacterial CRISPR/Cas9 system provides an effective method to disrupt gene function in mammalian cells, and has been applied to genome-wide screens. Here, we compare the efficacy of genome-wide CRISPR/Cas9-mediated forward genetic screens versus gene-trap...
The advent of new technologies such as high dynamic range or 8K screens has enhanced the quality digital images but it also increased codecs’ computational demands to process data. This paper presents a video codec that, while providing same coding features and performance those JPEG2000, can 16K in real time using consumer-grade GPU. throughput is achieved with technique that introduces comple...
