Plenoptic cameras, constructed with internal microlens arrays, capture both spatial and angular information, i.e., the full four-dimensional radiance, of a scene. The design of traditional plenoptic cameras assumes that each microlens image is completely defocused with respect to the image created by the main camera lens. As a result, only a single pixel in the final image is rendered from each...

Purpose of this paper The paper provides a better understanding of the interrelatedness of customer and service orientations in the organizational structures of capital goods manufacturing companies. Design/methodology/approach A qualitative, multi-case research design was employed using 36 European capital goods manufacturing companies. Findings This article explored four different patterns of...

The heterogeneity of CD4+ T cells has been investigated since the late 1970s, when their Th1 and Th2 subsets were coined. Later studies on the cutaneous form of the Leishmaniasis were focused on the experimental models of Leishmania major infection using the susceptible BALB/c and the resistant C57BL/6 mice. At the early 21st century, the regulatory T-cells subpopulation was introduced and its ...

With the rapid development of network and information technology, there is a wealth of huge amounts of data on the internet. But it’s a major problem faced by the majority of researchers how to effectively filter out a particular subject or field of information from these data. In this paper, we try to builder a focused crawler based on vector space model and TFIDF text correlation analysis. We...

This article presents a novel crawling and clustering method for extracting and processing cultural data from the web in a fully automated fashion. Our architecture relies upon a ‘focused’ web crawler to download web documents relevant to culture. The term ‘focused crawler’ refers to web crawlers that search and process only those web pages that are relevant to a particular topic. After downloa...

BACKGROUND Breast fibroadenomata (FAD) are the most common benign lesions in women. For palpable lesions, there are currently three standard treatment options: reassurance (with or without follow-up), vacuum-assisted mammotomy (VAM) or surgical excision. High-intensity focused ultrasound (HIFU) ablation has been used in the treatment of FAD. The drawback of HIFU is its prolonged treatment durat...

High-intensity focused ultrasound (HIFU) is a noninvasive treatment that induces complete coagulative necrosis of a tumor at depth through the intact skin. We evaluated a biochemical disease-free rate, safety and morbidity for localized prostate cancer treated with HIFU. A total of 132 consecutive patients with stage T1c-2N0M0 localized prostate cancer underwent HIFU using Sonablate-500 (Focus ...
