  text: <jats:title>Abstract</jats:title><jats:p>We present a novel approach for the
    simulation of solid to solid phase‐transformations in polycrystalline materials.
    To facilitate the utilization of a non‐affine micro‐sphere formulation with volumetric‐deviatoric
    split, we introduce Helmholtz free energy functions depending on volumetric and
    deviatoric strain measures for the underlying scalar‐valued phase‐transformation
    model. As an extension of affine micro‐sphere models [5], the non‐affine micro‐sphere
    formulation with volumetric‐deviatoric split allows to capture different Young's
    moduli and Poisson's ratios on the macro‐scale [1]. As a consequence, the temperature‐dependent
    free energy assigned to each individual phase takes the form of an elliptic paraboloid
    in volumetric‐deviatoric strain space, where the energy landscape of the overall
    material is obtained from the contributions of the individual constituents. For
    the evolution of volume fractions, we use an approach based on statistical physics–taking
    into account actual Gibbs energy barriers and transformation probabilities [2].
    The computation of individual energy barriers between the phases considered is
    enabled by numerical minimization of parametric intersection curves of elliptic
    Gibbs energy paraboloids. (© 2012 Wiley‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)</jats:p>

  text: Conventional alkaline solutions used for capacitive performance of electrodeposited
    cobalt hydroxides have a number of disadvantages as they are corrosive, environmentally
    unfriendly and provide a small working potential range. In this study, the capacitive
    properties of electrodeposited cobalt hydroxide/oxide were investigated in 1 M
    Na2SO4 solution with pH 5.5 by means of cyclic voltammetry, galvanostatic charging/discharging
    experiments and electrochemical impedance spectroscopy. The capacitance of the
    cobalt hydroxide/oxide was demonstrated to have high values of 141 F g−1 at scan
    rate 8 mV s−1 in this 1 M Na2SO4 solution. The anodic potential range is extended
    by 0.8–1.3 V vs. Ag/AgCl. A good cyclic stability and reversibility were observed.

  text: "In this paper we introduce the concept of an overall power function that
    is meant\r\nto combine two sources of a party’s power in a parliament. The first
    source is based\r\non the possibilities for the party to be part of a majority
    coalition and it is typically\r\nmodeled using a cooperative simple game. The
    second source takes into account\r\nparties’ asymmetries outside the cooperative
    game and it is displayed by a vector\r\nof exogenously given weights. We adopt
    a normative point of view and provide an\r\naxiomatic characterization of a specific
    overall power function, in which the weights\r\nenter in a proportional fashion."

abstract:

  text: <jats:p>There are no published data regarding the overall dietary glycaemic
    index (GI) and glycaemic load (GL) of Australian children and adolescents. We
    therefore aim to describe the dietary GI and GL of participants of the 2007 Australian
    National Children's Nutrition and Physical Activity Survey (2007ANCNPAS), and
    to identify the main foods contributing to their GL. Children, aged 2–16 years,
    who provided two 24 h recalls in the 2007ANCNPAS were included. A final dataset
    of 4184 participants was analysed. GI of each food item was assigned using a previously
    published method. GL was calculated, and food groups contributing to the GL were
    described by age group and sex. The weighted mean dietary GI and GL of the participants
    were 54 (<jats:sc>sd</jats:sc> 5) and 136 (<jats:sc>sd</jats:sc> 44), respectively.
    Among the nutrients examined, Ca had the highest inverse relationship with GI
    (<jats:italic>P</jats:italic> &lt; 0·001), while percentage energy from starch
    was most positively associated with GI. The association between fibre density
    and GI was modest, and percentage energy from sugar had an inverse relationship
    with GI. Daily dietary GL contributed by energy-dense and/or nutrient-poor (EDNP)
    items in subjects aged 14–16 years was more than doubled that of subjects aged
    2–3 years. To conclude, Australian children and adolescents were having a high-GI
    dietary pattern characterised by high-starchy food intake and low Ca intake. A
    significant proportion of their dietary GL was from EDNP foods. Efforts to reduce
    dietary GI and GL in children and adolescents should focus on energy-dense starchy
    foods.</jats:p>

  text: <jats:p>The aim of the present study was to examine the association of pre-pubertal
    dietary energy density (ED) with both age and body fatness at the start of the
    pubertal growth spurt (age at take-off, ATO). Analyses included 219 DOrtmund Nutritional
    and Anthropometric Longitudinally Designed Study participants with sufficient
    height measurements to estimate ATO who provided 3 d weighed dietary records at
    baseline, i.e. 2 and 3 years before ATO (mean age 6·9 (<jats:sc>sd</jats:sc> 1·2)
    years). Mean energy intakes and amounts of foods/drinks consumed at baseline were
    derived from the records. ED (kJ/g) was calculated based on (1) all foods and
    drinks (ED_all), (2) foods and energy-containing drinks (ED_energy), (3) foods
    and milk as a drink, but no other beverages (ED_milk) and (4) foods only, solid
    or liquid (ED_food). Using multiple regression analyses, the association between
    the ED variables and ATO was investigated. Furthermore, <jats:italic>Z</jats:italic>-scores
    of BMI and fat mass index (FMI) at ATO were considered as outcomes to reflect
    body fatness at puberty onset. The results showed that ED at baseline was not
    associated with ATO, regardless of the ED method used. For example, mean ATO in
    the lowest <jats:italic>v.</jats:italic> highest tertile of ED_food was 9·3 (95 %
    CI 9·0, 9·5) <jats:italic>v.</jats:italic> 9·4 (95 % CI 9·1, 9·7) years, <jats:italic>P</jats:italic><jats:sub>trend</jats:sub> = 0·8
    (adjusted for sex, maternal age, birth weight, dietary protein, dietary fibre,
    baseline BMI <jats:italic>Z</jats:italic>-score). Similarly, ED was not independently
    associated with BMI or FMI <jats:italic>Z</jats:italic>-score at ATO (<jats:italic>P</jats:italic><jats:sub>trend</jats:sub> = 0·3–0·9).
    In conclusion, dietary ED in childhood did not influence timing or body fatness
    at ATO in this cohort of healthy, free-living children.</jats:p>

  text: Alkylphosphonic acids of different alkyl chain lengths were adsorbed on electrochemically
    polished NiTi surfaces from ethanolic solutions. The electropolishing process
    led to passive films mainly composed of Ti-oxyhydroxide. The surface showed nanoscopic
    etching pits with a depths of about 2 nm and a diameter of about 20 nm. The interfacial
    binding mechanism of the phosphonic acid group to the oxyhydroxide surface and
    the ordering of the monolayer were spectroscopically analysed by means of infrared
    reflection absorption FTIR-spectroscopy with (PM-IRRAS) and without (IRRAS) photoelastic
    modulation. The comparison of IRRAS and PM-IRRAS data of the long chain octadecylphosphonic
    acid monolayer proved that the binding mechanism of the phosphonic acid group
    to the oxyhydroxide surface is based on a mono-or bidentate bond, which is not
    stable in the presence of high water activities. An alkyl chain length of 17 CH2
    groups is required for the formation of self-assembled monolayers, which are stable
    in aqueous environments. These long chain aliphatic organophosphonic acid monolayers
    were shown to inhibit anodic and cathodic surface reactions. (C) 2010 Elsevier

  text: "This paper deals with the design of efficiently computable incentive-compatible
    mechanisms for combinatorial optimization problems with single-minded agents each
    possibly having multiple private parameters. We focus on approximation algorithms
    for NP-hard mechanism design problems. These algorithms need to satisfy certain
    monotonicity properties to ensure truthfulness. Since most of the known approximation
    techniques do not fulfill these properties, we study alternative techniques. Our
    first contribution is a quite general method to transform a pseudopolynomial algorithm
    into a monotone fully polynomial time approximation scheme (FPTAS). This can be
    applied to various problems like, e.g., knapsack, constrained shortest path, or
    job scheduling with deadlines. For example, the monotone FPTAS for the knapsack
    problem gives a very efficient, truthful mechanism for single-minded multiunit
    auctions. The best previous result for such auctions was a 2-appro-xi-ma-tion.
    In addition, we present a monotone PTAS for the generalized assignment problem
    with any constant number of private parameters per agent. The most efficient way
    to solve packing integer programs (PIPs) is linear programming–based randomized
    rounding, which also is in general not monotone. We show that primal-dual greedy
    algorithms achieve almost the same approximation ratios for PIPs as randomized
    rounding. The advantage is that these algorithms are inherently monotone. This
    way, we can significantly improve the approximation ratios of truthful mechanisms
    for various fundamental mechanism design problems like single-minded combinatorial
    auctions (CAs), unsplittable flow routing, and multicast routing. Our primal-dual
    approximation algorithms can also be used for the winner determination in CAs
    with general bidders specifying their bids through an oracle.\r\n"

  text: "We investigate nonparametric multiproduct pricing problems, in which we want
    to find revenue maximizing prices for products $\\mathcal{P}$ based on a set of
    customer samples $\\mathcal{C}$. We mostly focus on the unit-demand case, in which
    products constitute strict substitutes and each customer aims to purchase a single
    product. In this setting a customer sample consists of a number of nonzero values
    for different products and possibly an additional product ranking. Once prices
    are fixed, each customer chooses to buy one of the products she can afford based
    on some predefined selection rule. We distinguish between the min-buying, max-buying,
    and rank-buying models. Some of our results also extend to single-minded pricing,
    in which case products are strict complements and every customer seeks to buy
    a single set of products, which she purchases if the sum of prices is below her
    valuation for that set. For the min-buying model we show that the revenue maximization
    problem is not approximable within factor $\\mathcal{O}(\\log^{\\varepsilon}|\\mathcal{C}|)$
    for some constant $\\varepsilon>0$, unless $\\mathrm{NP}\\subseteq\\mathrm{DTIME}(n^{\\mathcal{O}(\\log\\log
    n)})$, thereby almost closing the gap between the known algorithmic results and
    previous lower bounds. We also prove inapproximability within $\\mathcal{O}(\\ell^{\\varepsilon})$,
    $\\ell$ being an upper bound on the number of nonzero values per customer, and
    $\\mathcal{O}(|\\mathcal{P}|^{\\varepsilon})$ under slightly stronger assumptions
    and provide matching upper bounds. Surprisingly, these hardness results hold even
    if a price ladder constraint, i.e., a predefined order on the prices of all products,
    is given. Without the price ladder constraint we obtain similar hardness results
    for the special case of uniform valuations, i.e., the case that every customer
    has identical values for all the products she is interested in, assuming specific
    hardness of the balanced bipartite independent set problem in constant degree
    graphs or hardness of refuting random 3CNF formulas. Introducing a slightly more
    general problem definition in which customers are given as an explicit probability
    distribution, we obtain inapproximability within $\\mathcal{O}(|\\mathcal{P}|^{\\varepsilon})$
    assuming $\\mathrm{NP}\\nsubseteq\\bigcap_{\\delta>0}\\mathrm{BPTIME}(2^{\\mathcal{O}(n^{\\delta})})$.
    These results apply to single-minded pricing as well. For the max-buying model
    a polynomial-time approximation scheme exists if a price ladder is given. We give
    a matching lower bound by proving strong NP-hardness. Assuming limited product
    supply, we analyze a generic local search algorithm and prove that it is 2-approximate.
    Finally, we discuss implications for the rank-buying model.\r\n"
