    Histopathological image analysis : a review

    Get PDF
    Over the past decade, dramatic increases in computational power and improvement in image analysis algorithms have allowed the development of powerful computer-assisted analytical approaches to radiological data. With the recent advent of whole slide digital scanners, tissue histopathology slides can now be digitized and stored in digital image form. Consequently, digitized tissue histopathology has now become amenable to the application of computerized image analysis and machine learning techniques. Analogous to the role of computer-assisted diagnosis (CAD) algorithms in medical imaging to complement the opinion of a radiologist, CAD algorithms have begun to be developed for disease detection, diagnosis, and prognosis prediction to complement the opinion of the pathologist. In this paper, we review the recent state of the art CAD technology for digitized histopathology. This paper also briefly describes the development and application of novel image analysis technology for a few specific histopathology related problems being pursued in the United States and Europe

Resources supporting this work were pro-vided by the CEAFMC and Universidad de Huelva High Performance Computer (HPC@UHU) funded by ERDF/MINECO project UNHU-15CE-2848.A digital quantum simulation of the Agassi model from nuclear physics is proposed and analyzed. The proposal is worked out for the case with four different sites. Numerical simulations and analytical estimations are presented to illustrate the feasibility of this proposal with current technology. The proposed approach is fully scalable to a larger number of sites. The use of a quantum correlation function as a probe to explore the quantum phases by quantum simulating the time dynamics, with no need of computing the ground state, is also studied. Evidence is given showing that the amplitude of the time dynamics of a correlation function in this quantum simulation is linked to the different quantum phases of the system. This approach establishes an avenue for the digital quantum simulation of useful models in nuclear physics.Consejería de Trans-formación Económica, Industria, Conocimiento y Universidades de la Junta de Andalucía (Spain) and ERDF under Groups FQM-160, FQM-177, and FQM-370, and under projects P20-00617, P20-00764, P20-01247, UHU-1262561, and US-1380840PGC2018-095113-B-I00, PID2019-104002GB-C21, PID2019-104002GB-C22, and PID2020-114687GB-I00 funded by MCIN/AEI/10.13039/50110001103“ERDF A way of making Europe” and by ERDF, ref.

    The Industry and Policy Context for Digital Games for Empowerment and Inclusion:Market Analysis, Future Prospects and Key Challenges in Videogames, Serious Games and Gamification

    Get PDF
    The effective use of digital games for empowerment and social inclusion (DGEI) of people and communities at risk of exclusion will be shaped by, and may influence the development of a range of sectors that supply products, services, technology and research. The principal industries that would appear to be implicated are the 'videogames' industry, and an emerging 'serious games' industry. The videogames industry is an ecosystem of developers, publishers and other service providers drawn from the interactive media, software and broader ICT industry that services the mainstream leisure market in games, The 'serious games' industry is a rather fragmented and growing network of firms, users, research and policy makers from a variety of sectors. This emerging industry is are trying to develop knowledge, products, services and a market for the use of digital games, and products inspired by digital games, for a range of non-leisure applications. This report provides a summary of the state of play of these industries, their trajectories and the challenges they face. It also analyses the contribution they could make to exploiting digital games for empowerment and social inclusion. Finally, it explores existing policy towards activities in these industries and markets, and draws conclusions as to the future policy relevance of engaging with them to support innovation and uptake of effective digital game-based approaches to empowerment and social inclusion.JRC.J.3-Information Societ

    Popular education and the digital citizen: a genealogical analysis

    Get PDF
    This paper historicises and problematises the concept of the digital citizen and how it is constructed in Sweden today. Specifically, it examines the role of popular education in such an entanglement. It makes use of a genealogical analysis to produce a critical ‘history of the present’ by mapping out the debates and controversies around the emergence of the digital citizen in the 1970s and 1980s, and following to its manifestations in contemporary debates. This article argues that free and voluntary adult education (popular education) is and has been fundamental in efforts to construe the digital citizen. A central argument of the paper is that popular education aiming for digital inclusion is not a 21st century phenomenon; it actually commenced in the 1970s. However, this digitisation of citizens has also changed focus dramatically since the 1970s. During the 1970s, computers and computerisation were described as disconcerting, and as requiring popular education in order to counter the risk of the technology “running wild”. In current discourses, digitalisation is constructed in a non-ideological and post-political way. These post-political tendencies of today can be referred to as a post-digital present where computers have become so ordinary, domesticized and ubiquitous in everyday life that they are thereby also beyond criticism.

    "Re-engineering Cyprus" : information technologies and transformation processes in the Republic of Cyprus

    Get PDF
    By most Western Europeans Cyprus is probably perceived as a tourist resort rather than a technologically highly developed country. Interested German visitors are informed by the travel brochure published by the Republic of Cyprus' tourist office that "in the villages old customs and traditions still exist" (Zypern. 9000 Jahre Geschichte und Kultur 1997, 11). Pictures of places of antiquity, churches, monasteries, fortresses, archaic villages and of people engaged in agricultural work and crafts convey the image of a traditional Mediterranean society. However, the Republic of Cyprus is a rapidly modernising country. It has developed recently "from a poor agrarian into a high-income service economy" (Christodoulou 1995, 11) and "radical transformation processes" are observed (cf. ibid., 18). The forthcoming accession to the European Union additionally accelerates the pace of these transformation processes. Due to its position on the extreme rim of Europe in the Eastern Mediterranean region at the crossroads of three continents, the island is perceived both as marginal (cf. Pace 1999) and as a link between Europe and the Asian and African continents (cf. Kasoulides 1999). Cyprus is conceptualised for the future as a centre and intersection: as regional hub of the modern capital market, as communications and trade centre in the Eastern Mediterranean, as "telecommunications hub for the Eastern Mediterranean and Middle East region", as "international services centre". The Republic of Cyprus has a highly developed telecommunications infrastructure, which is the basic prerequisite for the conversion into such a centre and is one of the most important factors for the economic competitiveness of Cyprus. The global nature of communication platforms today, especially the Internet, is regarded as the key to the integration of Cyprus into the world economy. By implementing information technologies and promoting necessary expertise, economic progress and modernisation of the country as well as its global competitiveness is assumed to be guaranteed. Investments in the information technology infrastructure are regarded as essential for the development of Cyprus, fostering the implementation of the information society. This aim and the necessary implementation measures feature increasingly on the agendas of scientific and economic conferences and symposia in Cyprus
