  text: 'This chapter presents an overview of the contributions in TSG 1: Early Childhood
    Mathematics Education at ICME-13 which focused on issues from the perspective
    of early childhood educators. A basic assumption of this chapter is that the opportunities
    for young children to develop mathematical understandings and skills are influenced
    by several conditions at a macro, meso and micro level. First, curricula provide
    a framework for early mathematics teaching and learning with varying expectations
    (by teachers) about what can occur in the pre-school environment—informal learning
    (such as through play), content to learn and activities to experience. Second,
    early childhood educators’ mathematical knowledge, pedagogical knowledge, understandings,
    beliefs, and perceptions influence how they enact these expectations. These competencies
    can be developed and supported by professional learning. Third, educational programs,
    resources and activities used in the pre-school environment impact on the mathematical
    opportunities children engage in at the micro level.'

  text: Transistor and interconnect wearout is accelerated with transistor scaling
    resulting in timing variations and consequently reliability challenges in digital
    circuits. With the emergence of new issues like Electro-migration these problems
    are getting more crucial. Age monitoring methods can be used to predict and deal
    with the aging problem. Selecting appropriate locations for placement of aging
    monitors is an important issue. In this work we propose a procedure for selection
    of appropriate internal nodes that expose smaller overheads to the circuit, using
    correlation between nodes and the shareability amongst them. To select internal
    nodes, we first prune some nodes based on some attributes and thus provide a near-optimal
    solution that can effectively get a number of internal nodes and consider the
    effects of electro-migration as well. We have applied our proposed scheme to several
    processors and ITC benchmarks and have looked at its effectiveness for these circuits.

  text: In this paper, we present a monolithically integrated coherent receiver with
    on-chip grating couplers, 90° hybrid, photodiodes and transimpedance amplifiers.
    A transimpedance gain of 7.7 kΩ was achieved by the amplifiers. An opto-electrical
    3 dB bandwidth of 34 GHz for in-phase and quadrature channel was measured. A real-time
    data transmission of 64 GBd-QPSK (128 Gb/s) for a single polarization was performed.

    Two smooth map germs are right-equivalent if and only if they
    generate two Lagrangian submanifolds in a cotangent bundle which have the

    to this classical result of Golubitsky and Guillemin. Two Lagrangian submanifolds of a symplectic manifold have the same contact with a third Lagrangian
    submanifold if and only if the intersection problems correspond to stably right

    This gives rise to a framework which allows a natural transportation of the

    cal Lagrangian intersection problems. An application is the classification of
    Lagrangian boundary value problems for symplectic maps.

  text: 'In this paper we continue our study of bifurcations of solutions of boundary-value
    problems for symplectic maps arising as Hamiltonian diffeomorphisms. These have
    been shown to be connected to catastrophe theory via generating functions and
    ordinary and reversal phase space symmetries have been considered. Here we present
    a convenient, coordinate free framework to analyse separated Lagrangian boundary
    value problems which include classical Dirichlet, Neumann and Robin boundary value
    problems. The framework is then used to prove the existence of obstructions arising
    from conformal symplectic symmetries on the bifurcation behaviour of solutions
    to Hamiltonian boundary value problems. Under non-degeneracy conditions, a group
    action by conformal symplectic symmetries has the effect that the flow map cannot
    degenerate in a direction which is tangential to the action. This imposes restrictions
    on which singularities can occur in boundary value problems. Our results generalise
    classical results about conjugate loci on Riemannian manifolds to a large class
    of Hamiltonian boundary value problems with, for example, scaling symmetries. '

  text: The exploration of FPGAs as accelerators for scientific simulations has so
    far mostly been focused on small kernels of methods working on regular data structures,
    for example in the form of stencil computations for finite difference methods.
    In computational sciences, often more advanced methods are employed that promise
    better stability, convergence, locality and scaling. Unstructured meshes are shown
    to be more effective and more accurate, compared to regular grids, in representing
    computation domains of various shapes. Using unstructured meshes, the discontinuous
    Galerkin method preserves the ability to perform explicit local update operations
    for simulations in the time domain. In this work, we investigate FPGAs as target
    platform for an implementation of the nodal discontinuous Galerkin method to find
    time-domain solutions of Maxwell's equations in an unstructured mesh. When maximizing
    data reuse and fitting constant coefficients into suitably partitioned on-chip
    memory, high computational intensity allows us to implement and feed wide data
    paths with hundreds of floating point operators. By decoupling off-chip memory
    accesses from the computations, high memory bandwidth can be sustained, even for
    the irregular access pattern required by parts of the application. Using the Intel/Altera
    OpenCL SDK for FPGAs, we present different implementation variants for different
    polynomial orders of the method. In different phases of the algorithm, either
    computational or bandwidth limits of the Arria 10 platform are almost reached,
    thus outperforming a highly multithreaded CPU implementation by around 2x.

  text: "We present the submatrix method, a highly parallelizable method for the approximate
    calculation of inverse p-th roots of large sparse symmetric matrices which are
    required in different scientific applications. Following the idea of Approximate
    Computing, we allow imprecision in the final result in order to utilize the sparsity
    of the input matrix and to allow massively parallel execution. For an n x n matrix,
    the proposed algorithm allows to distribute the calculations over n nodes with
    only little communication overhead. The result matrix exhibits the same sparsity
    pattern as the input matrix, allowing for efficient reuse of allocated data structures.\r\n\r\nWe
    evaluate the algorithm with respect to the error that it introduces into calculated
    results, as well as its performance and scalability. We demonstrate that the error
    is relatively limited for well-conditioned matrices and that results are still
    valuable for error-resilient applications like preconditioning even for ill-conditioned
    matrices. We discuss the execution time and scaling of the algorithm on a theoretical
    level and present a distributed implementation of the algorithm using MPI and
    OpenMP. We demonstrate the scalability of this implementation by running it on
    a high-performance compute cluster comprised of 1024 CPU cores, showing a speedup
    of 665x compared to single-threaded execution."
