    Multimodal display techniques with application to breast imaging

    Application of a multimodality approach is advantageous for detection, diagnosis and management of breast cancer. In this context, F-18-FDG positron emission tomography (PET), and high-resolution and dynamic contrast-enhanced magnetic resonance imaging (MRI) have steadily gained clinical acceptance. Obtaining the spatial relationships between these modalities and conveying them to the observer maximizes the benefit that can be achieved. Traditionally the registered images are displayed side by side. However, it is believed that a combined MRI/PET display may be more beneficial. The advantage of a combined image lies in our inability to visually judge spatial relationships between images when they are viewed side by side. The process of combining the MRI and PET 3D images into a single 3D image is called image fusion. Color tables were defined for the fusion of MRI/PET images. This included color tables, which satisfy specific requirements, that were generated by a previously developed genetic algorithm. Radiologists were asked to evaluate images created using the selected fusion-for-visualization techniques. The study determined radiologists’ preference, ease of use, understanding, efficiency, and accuracy when reading images using each technique. The data studied, the data collected, the applications used to administer the study and analyze the results, and the processed results are provided through this interactive document

    Barcoding Fauna Bavarica – Capturing Central European Animal Diversity

    Get PDF
    The Barcoding Fauna Bavarica (BFB) is an All Species Barcoding campaign ran by the Zoologische Staatssammlung in Munich and the Canadian Centre for DNA Barcoding (www. faunabavarica.de). Core funding comes from the Bavarian Ministry for Science, Research and the Arts and from Genome Canada through the Ontario Genomics Institute. The initial funding period is from 2009–2013. Bavaria has the highest biodiversity of all German states, with at least 35000 animal species reported, representing a significant portion of the central European species diversity. Ecoregions include high altitude biomes, foothill areas and forested lowlands. The Zoologische Staatssammlung (ZSM) is one of the largest German natural history research institutions. It holds the world’s largest collection of Lepidoptera and Germany’s largest Hymenoptera collection. Since mid-2009, the BFB project has contributed DNA barcode records from 7208 specimens representing 3000 species and is therefore, after less than one year, one of the most comprehensive sources for local DNA barcode data. The focus groups for the initial phase were Lepidoptera (1820 species barcoded), bees (316 species), ants (39 species) and aquatic insects (322 species). Work on these focal groups will continue during 2010, with the goal to complete 80% of the Bavarian focal group species by the end of the year. New focal groups are Diptera, Mollusca, all Vertebrata and terrestrial Coleoptera, targeting 2000 species in 2010. Most tissue samples come from specimens in the ZSM collection, and where this was not feasible from freshly collected and identified specimens. This rapid progress reflects the strong involvement of taxonomists throughout the process, which is one of our key missions. We have implemented a system which co-ordinates vouchers stored in our main collection, with tissues as well as DNA samples in our DNA bank

    EDUCAÇÃO DE ADULTOS – OS CURSOS DE FORMAÇÃO PROFISSIONALIZANTE: UMA ALTERNATIVA PARA O EXERCÍCIO GLOBAL DE CIDADANIA

    Get PDF
    Este trabalho é resultado da reflexão conjunta de seus autores em relação às práticas pedagógicas adotadas para a Educação de Adultos em cursos profissionalizantes – e à importância dos conteúdos programáticos na formação do indivíduo. Um dos desafios da atualidade é a formação do cidadão comprometido com o trabalho e a ética, aliados à competência. Os cursos profissionalizantes exercem importante papel nessa formação, não só pela aquisição e/ou ampliação de conhecimentos específicos como também oferece subsídios para melhor integrá-lo na sociedade. É indispensável ao indivíduo apropriar-se dos recursos e meios disponíveis no mercado aliados às novas tecnologias, para conferir-lhe um novo perfil de profissional sem, contudo, desprezar os fins educacionais que contribuem para o crescimento da pessoa. Cidadania não acontece, não é algo pronto, mas uma construção permanente do indivíduo, adquirindo novas posturas para viver em sociedade

    VisIT-Bench: A Benchmark for Vision-Language Instruction Following Inspired by Real-World Use

    Full text link
    We introduce VisIT-Bench (Visual InsTruction Benchmark), a benchmark for evaluation of instruction-following vision-language models for real-world use. Our starting point is curating 70 'instruction families' that we envision instruction tuned vision-language models should be able to address. Extending beyond evaluations like VQAv2 and COCO, tasks range from basic recognition to game playing and creative generation. Following curation, our dataset comprises 592 test queries, each with a human-authored instruction-conditioned caption. These descriptions surface instruction-specific factors, e.g., for an instruction asking about the accessibility of a storefront for wheelchair users, the instruction-conditioned caption describes ramps/potential obstacles. These descriptions enable 1) collecting human-verified reference outputs for each instance; and 2) automatic evaluation of candidate multimodal generations using a text-only LLM, aligning with human judgment. We quantify quality gaps between models and references using both human and automatic evaluations; e.g., the top-performing instruction-following model wins against the GPT-4 reference in just 27% of the comparison. VisIT-Bench is dynamic to participate, practitioners simply submit their model's response on the project website; Data, code and leaderboard is available at visit-bench.github.io

    The Scottish Mental Survey 1932 linked to the Midspan studies: a prospective investigation of childhood intelligence and future health

    Get PDF
    The Scottish Mental Survey of 1932 (SMS1932) recorded mental ability test scores for nearly all of the age group of children born in 1921 and at school in Scotland on 1st June 1932. The Collaborative and Renfrew/Paisley studies, two of the Midspan studies, obtained health and social data by questionnaire and a physical examination in the 1970s. Some Midspan participants were born in 1921 and may have taken part in the SMS1932, so might have mental ability data available from childhood. The 1921-born Midspan participants were matched with the computerised SMS1932 database. The total numbers successfully matched were 1032 out of 1251 people (82.5%). Of those matched, 938 (90.9%) had a mental ability test score recorded. The mean score of the matched sample was 37.2 (standard deviation [SD] 13.9) out of a possible score of 76. The mean (SD) for the boys and girls respectively was 38.3 (14.2) and 35.7 (13.9). This compared with 38.6 (15.7) and 37.2 (14.3) for boys and girls in all of Scotland. Graded relationships were found between mental ability in childhood, and social class and deprivation category of residence in adulthood. Being in a higher social class or in a more affluent deprivation category was associated with higher childhood mental ability scores and the scores reduced with increasing deprivation. Future plans for the matched data include examining associations between childhood mental ability and other childhood and adult risk factors for disease in adulthood, and modelling childhood mental ability, alongside other factors available in the Midspan database, as a risk factor for specific illnesses, admission to hospital and mortality
