    The chromosome conformation capture (3C) method has been invaluable in studying chromatin interactions in a population of cells at a resolution surpassing that of light microscopy, for example in the detection of functional contacts between enhancers and promoters. Recent developments in sequencing-based chromosomal contact mapping (Hi-C, 5C and 4C-Seq) have allowed researchers to interrogate pairwise chromatin interactions on a wider scale, shedding light on the three-dimensional organization of chromosomes. These methods present significant technical and bioinformatic challenges to consider at the start of the project. Here, we describe two alternative methods for Hi-C, depending on the size of the genome, and discuss the major computational approaches to convert the raw sequencing data into meaningful models of how genomes are organized.

    The International Professional Practice Partnership (IP3) was formed by the International Federation for Information processing (IFIP) in 2007 to fulfill the objective of creating a global ICT profession. This start of this programme were first presented at WCC 2008 in Milan and since then major advances have taken place – both in the collective understanding of the endeavour and also measured by actual achievements. This paper will contextualise the progress of IP3 by examining: why an ICT profession is needed and why it should be on a global basis; and the progress made by IP3 in establishing a global ICT profession.

    We consider the solution of a scalar Helmholtz equation where the potential (or index) takes two positive values, one inside a ball of radius $\eps$ and another one outside. In this short paper, we report that the results recently obtained in the two dimensional case in [1] can be easily extended to three dimensions. In particular, we provide sharp estimates of the size of the scattered field caused by this ball inhomogeneity, for any frequencies and any contrast. We also provide a broadband estimate, that is, a uniform bound for the scattered field for any contrast, and any frequencies outside of a set which tends to zero with $\eps$. 17 pages

    International audience; In this paper, we study the effect of smartphone camera exposure on the performance of optical camera communications (OCC) link. The exposure parameters of image sensor sensitivity (ISO), aperture and shutter speed are included. A static OCC link with a 8 × 8 red, green and blue (RGB) LED array employed as the transmitter and a smartphone camera as the receiver is demonstrated to verify the study. Signal-to-noise ratio (SNR) analysis at different ISO values, the effect of aperture and shutter speed on communication link quality is performed. While SNRs of 20.6 dB and 16.9 dB are measured at 1 m and 2 m transmission distance, respectively for a ISO value of 100, they are decreased to 17.4 dB and 13.32 dB for a ISO of 800. The bit error rate (BER) of a 1 m long OCC link with a camera's shutter speed of 1/6000 s is 1.3 × 10 −3 (i.e., below the forward error correction BER limit of 3.8 × 10 −3) and is dropped to 0.0125 at a shutter speed of 1/20 s. This study provides insight of the basic smartphone settings and the exposure adjustment for further complex OCC links.

    International audience; Orchestras of Digital Musical Instruments (DMIs) enable new musical collaboration possibilities, extending those of acoustic and electric orchestras. However the creation and development of these orchestras remain constrained. In fact, each new musical collaboration system or orchestra piece relies on a fixed number of musicians, a fixed set of instruments (often only one), and a fixed subset of possible modes of collaboration. In this paper, we describe a unified framework that enables the design of Digital Orchestras with potentially different DMIs and an expand-able set of collaboration modes. It relies on research done on analysis and classification of traditional and digital orchestras, on research in Collaborative Virtual Environments, and on interviews of musicians and composers. The BOEUF framework consists of a classification of modes of collaboration and a set of components for modelling digital orchestras. Integrating this framework into DMIs will enable advanced musical collaboration modes to be used in any digital orchestra, including spontaneous jam sessions.

    The UK Ministry of Defence (MoD) is focusing on and shifting toward a Network Enabled Capability (NEC) approach for improved military effect. This is being realised through the physical networking and coherent integration of existing and future resources including sensors, effectors, support services, and decision makers. This paper is a case study (for NEC) of how the development and use of scenarios for demonstrating academic research can aid and help manage innovation. It illustrates the development, use and application of a multiple stakeholder scenario within the NECTISE research programme that helped establish and exploit a collaborative multidisciplinary working environment and how it helped manage innovative academic research. Our experience suggests that this approach can support the engagement of multiple stakeholders with differing perceptions and priorities and will provide a scenario development strategy for improved research and innovation for many other large systems.

    This paper explores the sustainable manufacturing knowledge in the field of supply chain management in order to understand the best practices to diffuse sustainability across supply chain network. A systematic literature review was conducted, covering six databases by combinations of key-words between the periods of 1992 to November of 2013. A total of 92 peer-reviewed papers in English are reviewed. A lack of integration of the core SCM activities (purchasing, performance and collaboration) was found in the diffusion of environmental and social sustainability practices across supply chain. Thus, more studies are needed to cover the adoption of environmental and social practices into supply chain management activities and the process to diffuse them across the supply network. In addition, environmental issues have received more attention than social ones in both upstream and downstream supply chain management activities. Using the outputs of the literature review, a conceptual framework is proposed covered: 1) the interrelationship between the core upstream SCM activities (purchasing, suppliers´ performance assessment and collaboration with suppliers) and 2) the effect of internal cross function in upstream SCM activities.

    Part 1: Long and Short Papers; International audience; Chronic diseases are the main causes of premature deaths, and the number of these deaths keeps growing. People often do not understand, however, that by changing their diet and how much they exercise, they can drastically reduce their risk of being affected by chronic disease. The key to moderating people’s behaviour lies in raising awareness of the links between lifestyle and chronic disease and in supporting the adoption and maintenance of a healthy lifestyle. Despite rises in global spending on health care, the pressure on resources is growing as people live longer. With people already using technology for medical information, it is an opportune time to develop technologies that can be used to raise public awareness of the links between lifestyle choices and chronic disease, and facilitate behavioural change.

    Part 4: Enterprise Architecture; International audience; An executable model plays an important role on verifying the behavior and performance of an architecture. This paper summarizes the state of the art on the synthesis methods of the executable model for an architecture that is compliant with the Department of Defense Architecture Framework (DoDAF). To overcome the deficiencies of current executable modeling studies, a component data-focused method is proposed. Following the introduction of an executable modeling language named OPDL, the data elements of DoDAF Meta-model (DM2) required for building executable model is analyzed. The mapping relations between partial DM2 and OPDL elements are built. Finally, a process to create executable model is explained in detail.

    The paper depicts an experience-centred approach for innovation enabled by the Internet of Experiences. Based on findings from innovation research as well as the internet-based approaches of the web 2.0 and the Internet of Things, it is argued that artificial systems, e.g. intelligent products, are capable to make experience on their own out of interactions, similar to user-experience today. After an introduction into the field of “experience” from a knowledge management perspective, a broad definition for experience is suggested. According to this definition, the experience-making possibility of artificial conscious systems is substantiated. Based on these findings, an experience-centred innovation approach, utilizing experience from intelligent objects and human users, is argued. The main outcome of this section is a depiction of the Internet of Experiences.
