We present the LeVen computational system for simulation of the electro-mechanical function of the left ventricle (LV) of mammalian heart on parallel computers. A macroscopic LV model incorporates state-of-the-art cellular models, e.g., Ekaterinburg-Oxford (EO) model [1] or ten Tusscher-Noble-Noble-Panfilov (TNNP) [2]. Ventricular mechanical activity on the organ level is described by means of the modified massspring system method, while the cellular mechanics is based on the myofilament activity. An open architecture of the LeVen system is proposed, which allows one to add and use new mechanical and electrophysiological models. the parallelization is implemented using the OpenMP technology. the performance of the LeVen system on multicore CPUs is evaluated. Parallel LeVen implementation provides a significant speedup, but the scalability is limited.

2015 IEEE 9th international conference on Anti-counterfeiting,Security, and Identification(ASID)

作者： Biao Liang Yuchun Guo Yishuai Chen Zhe Zhang Electronics and Information Engineering Beijing Jiaotong University

the rapid development of Video On Demand(VoD) service especially in wireless network incurs huge bandwidth costs. To reduce the bandwidth pressure and improve the user experience, Wireless Service Providers(WSP) began deploy cache in the Mobile Switching Center(MSC) following the power law distribution observation of video popularity for the whole system. However, based on the Sina Video dataset we find that for each MSC the popularity distribution does not necessarily follow the power law distribution and hence it is beneficial for the MSCs to cooperate in cache based on the aggregated power law distribution. In this paper, we propose two models for cooperative cache among MSCs. One is cooperative cache model of MSCs of the same WSP, the other one is cooperative cache model of MSCs of different WSPs. then we propose a novel heuristic cache algorithm for the MSCs cooperation of the same WSP by considering the aggregated popularity distribution, the individual popularity distribution of each MSC and the physical distance among MSCs. We evaluate the performance of the proposed models and heuristic cache algorithm with the previously mentioned dataset. Results show that our heuristic cache algorithm is effective and efficient the performance gain reaches 88.48% of the performance gain of optimal solution at most. And the time cost reduces to 0.003% of that in the optimal solution by using cluster. In addition, we propose a number of visits interval method to select a proper cycle of cache update to obtain higher and more stable hit rate of cache.

this paper explores some a novel approaches to harnessing the Internet-of-things (IoT) as a teaching and research vehicle in education. For teaching we argue that the Internet-of-things provides a highly motivating topic to capture students' imaginations, and a perfect platform for teaching computer science. In addition, we explain the potential for entire campuses or buildings to be constructed from Internet-of-things technologies and the potential for this infrastructure to act as a teaching platform. this proposition is perfectly captured by the axiom "the college building (or campus) is the lab". this philosophy is part of a wider movement that started in the EU, called Living Labs. In achieving these aims, our work seeks to combine a number of concepts;first we utilise the Internet-of-things, second we incorporate Living Labs ideas, third we harness the iCampus vision, forth we use the 'Smart Box' concept and finally we implement the Pervasive-interactive-programming (PiP) paradigm. We contend this approach can be used in various mixes to produce highly motivating and effective educational environments. We illustrate this work by describing the application of these ideas to a real-world venture, the Harlow UTC (in the UK). the main focus of this paper concerns the use of PiP, together with the Internet-of-things, to teach elementary programming skills. In in support of this we present results of an evaluation of PiP with 18 participants (students and staff) of varied age and gender. the main conclusions of these evaluations were that PiP enabled students and staff, with diverse backgrounds, to quickly master the programming skills involved. the paper concludes by describing our future plans for this work.

the placement phase is the most crucial in the physical design synthesis of Very Large Scale Integrated (VLSI) system for achieving design with optimized routability, wirelength, timing usage and power. though placement comprises of three conventional approaches (e.g. global placement, legalization and detailed placement), we have only dealt with global placement which is the basis of other two phases in placement problem and is of great importance. With advancement in process technology and thus increased architectural complexity of circuits, the net list size of modern days VLSI design growing expeditiously, clustering for placement accelerated the placement process and provides better placement solution quality. To achieve good placement solution, a new clustering technique has been presented to segregate the nets into clusters based on the type of the circuit blocks and the connectivity among them. Meanwhile, a novel 0-1 Integer programming (0-1 IP) based lookahead legalization process has been proposed for global placement with the help of a new force-directed method to create regions in order to reduce the searching space for global placement. Instead of implementing legalization separate, it is combined with the global placement phase which in turn reduces overhead of legalization. We have tested the performance of our proposed algorithms on ISPD 2011 benchmark circuits for mixed-size design. the obtained results are at par with all existing placers for mixed-size design w.r.t overflow reduction and wirelength except run time.

In recent years, as long as the rapid development of aquaculture, the occurrence of aquatic animal diseases increase year by year, which restrict the sustained, steady, and healthy development of aquaculture. So the rapid diagnosis of aquatic animal disease is particularly important for their prevention and control. In the present work, an Android-based aquatic animal disease diagnostic system has been developed in order to provide more convenient and effective aquatic animal disease diagnostic services to ordinary farmers. the designed system includes the part of the man-machine interface(user interface, expert interface), inference engine, the case base, knowledge base and so on. Interactive interface is a visual display interface. Inference engine was written in the Java programming language. Case base and knowledge base were created using SQLite. the results show that ordinary farmers can easily use this system to realize the convenient, fast, and accurate access to the findings of disease diagnosis and prevention measures as well as aquaculture expert can add, delete,modify, view the case base and knowledge base at any time.

Designing intelligent environments is a complex, interdisciplinary process, performed by experts from different domains. these intelligent environments often consist of wireless sensor/actuator nodes that together form a network to achieve certain goals. While there are many prototyping tools and wireless nodes available, there are few that are suitable for use in interdisciplinary projects for people with varying backgrounds. We identify the need for an easy-to-learn platform that provides a smooth integration between soft- and hardware and offers possibilities for wireless networking. In this paper we discuss existing development platforms that are used by designers and identify qualities that are important for the design of intelligent environments. We then present the Lithne platform, consisting of nodes that are user programmable and software packages that facilitate wireless networking. One of the core qualities of the Lithne platform is the possibility to wirelessly program the nodes, allowing designers to develop intelligent environments iteratively in the actual context. Finally, we present cases in which Lithne has been used in the design and implementation of intelligent lighting environments.

the popularity of virtual worlds has increased in recent years, as they have begun to feature a three-dimensional (3D) environment, avatars, and synchronous and asynchrounous communication. However, to successfully use virtual world platforms in different disciplines, certain limitations and potential difficulties of these platforms must be overcome. the purpose of this study was both to determine technical problems encountered by practitioners and designers who create environments in 3D virtual worlds and to suggest solutions for these problems. In the study, designers experimented with two different 3D virtual world platforms for one year, to design and create learning environments. the case study method was used as a research model. To collect the research data, interview records and documents in which the designers and practitioners noted problems that they encountered were used. the results indicate that the technical problems influenced the pedagogical effectiveness of the environments. Our findings should be beneficial both to virtual world designers and to users who wish to use these environments in different fields.

Protein evolution driven by symmetric structural repeats

引用

BMC BIOINFORMATICS 2008年第s10期9卷 P3-P3页

作者： Abraham, Anne-Laure Pothier, Joel Rocha, Eduardo P. C. Univ Paris 06 F-75005 Paris France Inst Pasteur CNRS URA2171 F-75015 Paris France

Background Duplications play a major role in the evolution of genomes by creating and modifying molecular functions. Repeats are created at the DNA level, but when they are intragenic they affect protein sequence and structure. Moreover, as sequences evolve faster than 3D structures, some ancient repeats cannot be detected at the sequence level. therefore, an understanding of the evolutionary and functional role of repeats requires tracking them at the three levels. Materials and methods For this task we have developed a program (SWELFE) to find repeats in DNA, amino acid sequences and 3D protein structures (available at http://***/ swelfe). Repeats were searched independently at all three levels using dynamic programming (SIM algorithm) and we adapted scoring matrices for each level. 3D structures were encoded as strings of α angles (dihedral angle between four consecutive Cα) so that the same algorithm can be used at the three levels. We verified the validity of our approach by superimposing the 3D repeats. We made a statistical evaluation of the repeats we found. As there is currently no connection between 3D structures and the corresponding DNA sequences, we built a databank where we associate a PDB structure with its best match among the genes in TREMBL. the databank has 85 845 entries corresponding to ~85% of the unique chains of the PDB databank after removing entries with very small peptides or many undefined residues. We could then compare directly the results of repeat identification at the three levels. Results In our analyses we were surprised to find that many of the large structural repeats are symmetrical (2-fold symmetry): one copy of the repeat can be superimposed with the other copy by a simple rotation of 180° around an axis (some repeats have 3-fold symmetry or higher). An example of a symmetrical repeat is shown on Figure 1. then structures containing such repeats resemble to homodimers combined into one unit. [ABSTRACT FROM
