  text: A set of (Ga0.77In0.23)As/Ga(NxAs1−x) heterostructures is studied by time-resolved
    photoluminescence. Four samples with nitrogen concentrations from x=0.48% up to
    x=2.2% are investigated at different temperatures and with different excitation
    densities. The experiments suggest that the heterostructure band offset is type
    I for x=0.48% and type II for x=2.2%. The situation is more complex for x=0.72%
    and x=1.25%, since these samples are close to the transition from type I to type
    II. The experimental findings are analyzed using a detailed microscopic theory.
    Numerical calculations describe the measured data well. In particular, the interpretation
    of the experimental results concerning the band alignment is confirmed by the
    theoretical analysis.

    [M<jats:sup>2</jats:sup> = Cu, Ag, Au] to give chiral heterometallatetrahedranes

  text: Given a point set P in the d-dimensional unit hypercube, we give upper bounds
    on the maximal expected number of extreme points when each point is perturbed
    by small random noise chosen independently for each point from the same noise
    distribution &#916;. Our results are parametrized by the variance of the noise
    distribution. For large variance we essentially consider the average case for
    distribution &#916; while for variance 0 we consider the worst case. Hence our
    results give upper bounds on the number of extreme points where our input distributions
    range from average case to worst case.<br>Our main contribution is a rather general
    lemma that can be used to obtain upper bounds on the expected number of extreme
    points for a large class of noise distributions. We then apply this lemma to obtain
    explicit bounds for random noise coming from the Gaussian normal distribution
    of variance &#963;² and the uniform distribution in a hypercube of side length
    &epsilon. For these noise distributions we show upper bounds of O( (1/ &#963;
    )^d * log^3/2 * d - 1 n ) and O( ( (n log n) / &#949; )^d/(d+1) ), respectively.
    Besides its theoretical motivation our model is also motivated by the observation
    that in many applications of convex hull algorithms the input data is inherently
    noisy, e.g. when the data comes from physical measurement or imprecise arithmetic
    is used.

  text: 'For $c in REAL$, a $c$-spanner is a subgraph of a complete Euclidean graph
    satisfying that between any two vertices there exists a path of weighted length
    at most $c$ times their geometric distance. Based on this property to approximate
    a complete weighted graph, sparse spanners have found many applications, e.g.,
    in FPTAS, geometric searching, and radio networks. For geometric searching, it
    turned out to suffice whether the radius rather than the length of some path between
    any two vertices is bounded relatively to their geometric distance; this is the
    defining property of weak spanners. Finally regarding radio network applications,
    a power spanner accounts for the total energy afforded for a wireless transmission
    with the requirement that the sum of the squares of the lengths of some path between
    any two planar vertices must be bounded relatively to the square of their geometric
    distance (or higher powers up to 6 or even 8).<br><br>While it is known that any
    $c$-spanner is also both a weak $C_1$-spanner and a $C_2$-power spanner (for appropriate
    $C_1,C_2$ depending only on $c$ but not on the graph under consideration), we
    show that the converse fails: There exists a family of $c_1$-power spanners that
    are no weak $C$-spanners and also a family of weak $c_2$-spanners that are no
    $C$-spanners for any fixed $C$ (and thus no uniform spanners, either). However
    the deepest result of the present work reveals that, surprisingly, any weak spanner
    is also a uniform power spanner. We further generalize the latter notion by considering
    $(c,delta)$-power spanners where the sum of the $delta$-th powers of the lengths
    has to be bounded; so $(cdot,2)$-power spanners coincide with the usual power
    spanners and $(cdot,1)$-power spanners are classical spanners. Interestingly,
    these $(cdot,delta)$-power spanners form a strict hierarchy where the above results
    still hold for any $deltageq2$; some even hold for $delta>1$ while counterexamples
    reveal others to fail for $delta<2$. In fact we show that in general every self-similar
    curve of fractal dimension $d>delta$ is no $(C,delta)$-power spanner for any fixed
    $C$. '

  text: "The visualisation of manufacturing-processes assists the user in understanding
    and analysis.\r\nTypically he can move free and unguided in a virtual environment
    which visualizes the entire\r\nprocess. Thus knowledge and conclusions are to
    some extend acquired on a random base.\r\nThis article describes the development
    of a tool, which enables the user to interactively improve\r\nsignificant production
    processes in the simulation. He moves in a virtual 3D-environment\r\n(walkthrough
    system) and is able to acquire automatically calculated indications for significant\r\nprocesses.
    At the same time the simulation considers significant objects in a more detailed
    way. If\r\nthe viewer is interested in a significant process, he is automatically
    guided to the relevant location\r\nwhere he can examine the critical situation
    by modification of the simulation model."
