Modeling human actors in an intelligent automated warehouse

Warehouse automation has progressed at a rapid pace over the last decade. While the tendency has been to implement fully automated solutions, most warehouses today exist as a mixture of manually operated and fully automated material handling sections. In such a hybrid warehouse, men and machines move around goods in between sections in order to retrieve, transport and stack goods according to their nature and quantity. The biggest challenge in hybrid warehouses is to optimize the alignment of manual and automatic processes in order to improve the flow of materials between storage areas and distribution centers. Integrating individuals as human actors in an automation solution is not straightforward due to unpredictable human behavior. In this paper, we will investigate how we can model the characteristics of human actors within an automation solution and how software systems can unify human actors with automated business processes to coordinate both as first class entities for logistics activities within a hybrid warehouse.status: publishe
Elliptic genera and characteristic q -series of superconformal field theory

We analyze the characteristic series, the KO series and the series associated with the Witten genus, and their analytic forms as the q -analogs of classical special functions (in particular q -analog of the beta integral and the gamma function). q -Series admit an analytic interpretation in terms of the spectral Ruelle functions, and their relations with appropriate elliptic modular forms can be described. We show that there is a deep correspondence between the characteristic series of the Witten genus and KO characteristic series, on one side, and the denominator identities and characters of N=2 superconformal algebras, and the affine Lie (super)algebras on the other. We represent the characteristic series in the form of double series using the Hecke–Rogers modular identity
Polymerisation of lignosulfonates by the laccase-HBT (1-hydroxybenzotriazole) system improves dispersibility

Prasetyo, Endry Nugroho et al.--The ability of laccases from Trametes villosa (TvL), Myceliophthora thermophila (MtL), Trametes hirsuta (ThL) and Bacillus subtilis (BsL) to improve the dispersion properties of calcium lignosulfonates 398 in the presence of HBT as a mediator was investigated. Size exclusion chromatography showed an extensive increase in molecular weight of the samples incubated with TvL and ThL by 107% and 572% from 28400 Da after 17 h of incubation, respectively. Interestingly, FTIR spectroscopy, 13C NMR and Py-GC/MS analysis of the treated samples suggested no substantial changes in the aromatic signal of the lignosulfonates, a good indication of the ability of TvL/ThL-HBT systems to limit their effect on functional groups without degrading the lignin backbone. Further, the enzymatic treatments led to a general increase in the dispersion properties, indeed a welcome development for its application in polymer blends.Financial support from the BIORENEW EU-project (NMP2-CT-2006-26456), Austrian Academic Exchange Programme (ÖEAD) and the Spanish projects BIO2007-28720-E, BIO2008-01533, and AGL2008-00709 is acknowledged.Peer reviewe
A new view of Italian seismicity using 20 years of instrumental recordings

Abstract
In this paper, we show the seismicity of the past 20 years that occurred in Italy and surrounding regions. Hypocentral
locations have been obtained by using P- and S-wave arrival times from the INGV national and several regional permanent
seismic networks. More than 48,000 events, selected from an original data set of about 99,780, are used to reconstruct the most
complete seismic picture of the Italian region so far. The seismicity distribution allows inference on seismotectonics of this
complex region of subduction versus continental collision. Our results clearly reveal the geometry of the Adria and the Ionian
subduction and a continuous normal fault belt in the upper crust, following the Apennines mountain range. The depth of the
seismogenic layer is computed from the cut-off of seismicity at depth and shows large variations along and across the seismic
active regions. Earthquakes are generated by the different velocity of slab retreat and the subsequent asthenospheric upwelling.

Measurement of neutron induced fission of 235-U, 233-U and 245-Cm with the FIC detector at the CERN n TOF facility

A series of measurements of neutron induced fission cross section of various TRU isotopes have been\ud
performed at the CERN n TOF spallation neutron facility, in the energy range from thermal to nearly 250 MeV.\ud
The experimental apparatus consists in a fast ionization chamber (FIC), used as a fission fragment detector with a\ud
high efficiency. Good discrimination between alphas and fission fragments can be obtained with a simple amplitude\ud
threshold. In order to allow the monitoring of the neutron beam and to extract the n TOF neutron flux, the well known\ud
cross section of the 235U(n,f) reaction, considered as a fission standard, has been used. Preliminary results for the\ud
cross section are shown for some selected isotopes such as 235U, 233U and 245Cm in the energy range from 0.050 eV\ud
to about 2MeV.Postprint (published version
Nature and origins of mathematics difficulties in very preterm children: A different etiology than Developmental Dyscalculia

Background. Children born very preterm (<32 weeks) are at high risk for mathematics\ud
learning difficulties that are out of proportion to other academic and cognitive deficits.\ud
However, the aetiology of mathematics difficulties in very preterm children is unknown. We\ud
sought to identify the nature and origins of preterm children’s mathematics difficulties.\ud
Methods. 115 very preterm children aged 8-10 years were assessed in school with a control\ud
group of 77 term-born classmates. Achievement in mathematics, working memory, visuospatial\ud
processing, inhibition and processing speed were assessed using standardised tests.\ud
Numerical representations and specific mathematics skills were assessed using experimental\ud
tests.\ud
Results. Very preterm children had significantly poorer mathematics achievement, working\ud
memory and visuo-spatial skills than term-born controls. Although preterm children had\ud
poorer performance in specific mathematics skills, there was no evidence of imprecise\ud
numerical representations. Difficulties in mathematics were associated with deficits in visuospatial\ud
processing and working memory.\ud
Conclusions. Mathematics difficulties in very preterm children are associated with deficits in\ud
working memory and visuo-spatial processing not numerical representations. Thus very\ud
preterm children’s mathematics difficulties are different in nature from those of children with\ud
developmental dyscalculia. Interventions targeting general cognitive problems, rather than\ud
numerical representations, are needed to improve very preterm children’s achievement.This study was funded by a project grant from Action Medical Research\ud

Evaluation of the Rhenium-Osmium geochronometer in the Phosphoria Petroleum System, Bighorn Basin of Wyoming and Montana, USA.

Rhenium–osmium (Re–Os) geochronometry is applied to crude oils derived from the Permian Phosphoria Formation of the Bighorn Basin in Wyoming and Montana to determine whether the radiogenic age reflects the timing of petroleum generation, timing of migration, age of the source rock, or the timing of thermochemical sulfate reduction (TSR). The oils selected for this study are interpreted to be derived from the Meade Peak Phosphatic Shale and Retort Phosphatic Shale Members of the Phosphoria Formation based on oil–oil and oil–source rock correlations utilizing bulk properties, elemental composition, δ13C and δ34S values, and biomarker distributions. The δ34S values of the oils range from −6.2‰ to +5.7‰, with oils heavier than −2‰ interpreted to be indicative of TSR. The Re and Os isotope data of the Phosphoria oils plot in two general trends: (1) the main trend (n = 15 oils) yielding a Triassic age (239 ± 43 Ma) with an initial 187Os/188Os value of 0.85 ± 0.42 and a mean square weighted deviation (MSWD) of 1596, and (2) the Torchlight trend (n = 4 oils) yielding a Miocene age (9.24 ± 0.39 Ma) with an initial 187Os/188Os value of 1.88 ± 0.01 and a MSWD of 0.05. The scatter (high MSWD) in the main-trend regression is due, in part, to TSR in reservoirs along the eastern margin of the basin. Excluding oils that have experienced TSR, the regression is significantly improved, yielding an age of 211 ± 21 Ma with a MSWD of 148. This revised age is consistent with some studies that have proposed Late Triassic as the beginning of Phosphoria oil generation and migration, and does not seem to reflect the source rock age (Permian) or the timing of re-migration (Late Cretaceous to Eocene) associated with the Laramide orogeny. The low precision of the revised regression (±21 Ma) is not unexpected for this oil family given the long duration of generation from a large geographic area of mature Phosphoria source rock, and the possible range in the initial 187Os/188Os values of the Meade Peak and Retort source units. Effects of re-migration may have contributed to the scatter, but thermal cracking and biodegradation likely have had minimal or no effect on the main-trend regression. The four Phosphoria-sourced oils from Torchlight and Lamb fields yield a precise Miocene age Re–Os isochron that may reflect the end of TSR in the reservoir due to cooling below a threshold temperature in the last 10 m.y. from uplift and erosion of overlying rocks.\ud
\ud
The mechanism for the formation of a Re–Os isotopic relationship in a family of crude oils may involve multiple steps in the petroleum generation process. Bitumen generation from the source rock kerogen may provide a reset of the isotopic chronometer, and incremental expulsion of oil over the duration of the oil window may provide some of the variation seen in 187Re/188Os values from an oil family.\u
Inverted-U relationship between R&D intensity and survival : evidence on scale and complementarity effects in UK data.

Existing evidence on the relationship between R&D intensity and firm survival is varied and often conflicting. We argue that this may be due to overlooking R&D scale effects and complementarity between R&D intensity and market concentration. Drawing on Schumpeterian models of competition and innovation, we address these issues by developing a formal model of firm survival and using a panel dataset of 37,930 of R&D-active UK firms over 1998–2012. We report the following findings: (i) the relationship between R&D intensity and firm survival follows an inverted-U pattern that reflects diminishing scale effects; (ii) R&D intensity and market concentration are complements in that R&D-active firms have longer survival time if they are in more concentrated industries; and (iii) creative destruction as proxied by median R&D intensity in the industry and the premium on business lending have negative effects on firm survival. Other findings concerning age, size, productivity, relative growth, Pavitt technology classes and the macroeconomic environment are in line with the existing literature. The results are strongly or moderately robust to different samples, stepwise estimations, and controls for frailty and left truncation
Effects of psychological and psychosocial interventions on sport performance: a meta-analysis

The final publication is available at Springer via http://dx.doi.org/10.1007/s40279-016-0552-7.Background: Psychologists are increasingly supporting the quest for performance enhancement in sport and there is a need to evaluate the evidence base underpinning their work. Objectives: To synthesize the most rigorous available research that has evaluated psychological, social, and psychosocial interventions with sport performers on variables relating to their athletic performance, and to address some of the perplexing issues in the sport psychology intervention literature (e.g., do interventions have a lasting effect on sport performance?). Methods: Randomized controlled trials were identified through electronic databases, hand-searching volumes of pertinent journals, scrutinizing reference lists of previous reviews, and contacting experts in the evaluation of interventions in this field. Included studies were required to evaluate the effects of psychological, social, or psychosocial interventions on sport performance in athletes when compared to a no-treatment or placebo-controlled treatment comparison group. A random effects meta-analysis calculating the standardized mean difference (Hedges’ g), meta-regressions, and trim and fill analyses were conducted. Data were analyzed at post-test and follow-up (ranging from 1 to 4 weeks after the intervention finished) assessments. Results: Psychological and psychosocial interventions were shown to enhance sport performance at post-test (k = 35, n = 997, Hedges’ g = 0.57, 95 % CI = 0.22–0.92) and follow-up assessments (k = 8, n = 189, Hedges’ g = 1.16, 95 % CI = 0.25–2.08); no social interventions were included or evaluated. Larger effects were found for psychosocial interventions and there was some evidence that effects were greatest in coach-delivered interventions and in samples with a greater proportion of male participants. Conclusions: Psychological and psychosocial interventions have a moderate positive effect on sport performance, and this effect may last at least a month following the end of the intervention. Future research would benefit from following guidelines for intervention reporting
Uncomfortable truths - teamworking under lean in the UK

This article responds to a recent contribution to this journal. Procter and Radnor (2014) provide an account of teamworking in the UK Civil Service, specifically Her Majesty’s Revenue and Customs (HMRC), which focuses on the relationship between recently implemented lean work organisation and teams and teamworking. This intervention is prompted by criticism of the present authors’ published research into lean in the same locus (e.g. Carter et al, 2011a;b; 2013 a;b). Procter and Radnor claim, without foundation we argue, that our work is ‘one-sided’ and that theirs delivers a ‘more nuanced’ analysis of lean in this government department and, it follows, of the lean phenomenon more generally. Our riposte critiques their article on several grounds. Firstly, it suffers from problems of logic and construction, conceptual confusion and definitional imprecision. Methodological difficulties and inconsistent evidence contribute additionally to analytical weakness. Included in our response are empirical findings on teamworking at HMRC, which challenge Proctor and Radnor’s evidential basis and further reveal the shortcomings of their interpretation
K$^-$ absorption on two nucleons and ppK$^-$ bound state search in the
  $\Sigma^0$p final state

We report the measurement of K$^-$ absorption processes in the $\Sigma^0$p
final state and the first exclusive measurement of the two nucleon absorption
(2NA) with the KLOE detector. The 2NA process without further interactions is
found to be 12\% of the sum of all other contributing processes, including
absorption on three and more nucleons or 2NA followed by final state
interactions with the residual nucleons. We also determine the possible
contribution of the ppK$^-$ bound state to the $\Sigma^0$p final state. A yield
of ppK$^- /\mathrm{K^-_{stop}}$ is found to be $(0.044 \pm 0.009\, stat ^{+
0.004} _{- 0.005} \,syst) \cdot 10^{-2}$ but its statistical significance based
on an F-test is only 1$\sigma$
Diphoton decay for a $750$ GeV scalar boson in an $U(1)_{X}$ model

In the context of a nonuniversal and anomaly free $U(1)_{X}$ extension of the
standard model, we examine the decay of a $750$GeV scalar singlet state,
$\xi_{\chi}$, as a possible explanation of the observed diphoton excess
announced by the ATLAS and CMS collaborations at CERN-LHC collider. One-loop
decay to photons is allowed through three heavy singlet quarks and one charged
Higgs boson into the loop. We obtain, for different width approximations and
for masses of the exotic singlet quarks in the region $[900,\,3000]$ GeV, a
production cross section $\sigma(pp\to\xi_{\chi}\to\gamma\gamma)$ compatible
with ATLAS and CMS collaborations data. We also include another scalar singlet,
$\sigma$, as a dark matter candidate that may couple with the 750 GeV scalar at
tree level with production cross sections in agreement with ATLAS and CMS.Comment: 5 figures, discussion extended, 2 new figure
MC1R gene variants and non-melanoma skin cancer: A pooled-analysis from the M-SKIP project

Background:The melanocortin-1-receptor (MC1R) gene regulates human pigmentation and is highly polymorphic in populations of European origins. The aims of this study were to evaluate the association between MC1R variants and the risk of non-melanoma skin cancer (NMSC), and to investigate whether risk estimates differed by phenotypic characteristics.Methods:Data on 3527 NMSC cases and 9391 controls were gathered through the M-SKIP Project, an international pooled-analysis on MC1R, skin cancer and phenotypic characteristics. We calculated summary odds ratios (SOR) with random-effect models, and performed stratified analyses.Results:Subjects carrying at least one MC1R variant had an increased risk of NMSC overall, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC): SOR (95%CI) were 1.48 (1.24-1.76), 1.39 (1.15-1.69) and 1.61 (1.35-1.91), respectively. All of the investigated variants showed positive associations with NMSC, with consistent significant results obtained for V60L, D84E, V92M, R151C, R160W, R163Q and D294H: SOR (95%CI) ranged from 1.42 (1.19-1.70) for V60L to 2.66 (1.06-6.65) for D84E variant. In stratified analysis, there was no consistent pattern of association between MC1R and NMSC by skin type, but we consistently observed higher SORs for subjects without red hair.Conclusions:Our pooled-analysis highlighted a role of MC1R variants in NMSC development and suggested an effect modification by red hair colour phenotype
Orthogonal Laurent polynomials on the unit circle, extended CMV ordering and 2D Toda type integrable hierarchies

We connect the theory of orthogonal Laurent polynomials on the unit circle and the theory of Toda-like integrable systems using the Gauss–Borel factorization of a Cantero–Moral–Velázquez moment matrix, that we construct in terms of a complex quasi-definite measure supported on the unit circle. The factorization of the moment matrix leads to orthogonal Laurent polynomials on the unit circle and the corresponding second kind functions. We obtain Jacobi operators, 5-term recursion relations, Christoffel–Darboux kernels, and corresponding Christoffel–Darboux formulas from this point of view in a completely algebraic way. We generalize the Cantero–Moral–Velázquez sequence of Laurent monomials, recursion relations, Christoffel–Darboux kernels, and corresponding Christoffel–Darboux formulas in this extended context. We introduce continuous deformations of the moment matrix and we show how they induce a time dependent orthogonality problem related to a Toda-type integrable system, which is connected with the well known Toeplitz lattice. We obtain the Lax and Zakharov–Shabat equations using the classical integrability theory tools. We explicitly derive the dynamical system associated with the coefficients of the orthogonal Laurent polynomials and we compare it with the classical Toeplitz lattice dynamical system for the Verblunsky coefficients of Szegő polynomials for a positive measure. Discrete flows are introduced and related to Darboux transformations. Finally, we obtain the representation of the orthogonal Laurent polynomials (and their second kind functions), using the formalism of Miwa shifts in terms of τ-functions and the subsequent bilinear equations.MM thanks economical support from the Spanish Ministerio de Ciencia e Innovación,

Transport Anisotropy and Impurity Scattering in Ge at Millikelvin Temperatures: Experimental Study

International audienceAnisotropy effects in hot carrier transport have been investigated in germanium crystals at mK temperatures in the electric field range pertaining to the operation of the Edelweiss dark matter detectors. Comparative measurements have been made on n-type specimens of different impurity contents, both ultra-pure (Nd-Na < 1010 cm-3) and doped to 1011 cm-3. At relatively high field intensities (>  5 V/cm), similar features of electron and hole transport are observed independent of the concentration of electrically active impurities. Differences appear at lower field (down to a fraction of a V/cm) with regard to electron straggling especially, dependent on crystal purity. These experiments demonstrate the importance on carrier transport of impurity scattering at low field, whereas phonon scattering becomes the dominant factor at higher field intensities
Experimental and Theoretical Studies of Quadrupolar Oligothiophene-Cored Chromophores Containing Dimesitylboryl Moieties as π-Accepting End-Groups: Syntheses, Structures, Fluorescence, and One- and Two-Photon Absorption

International audienceQuadrupolar oligothiophene chromophores composed of four to five thiophene rings with two terminal (E)-dimesitylborylvinyl groups (4 V-5 V), and five thiophene rings with two terminal aryldimesitylboryl groups (5 B), as well as an analogue of 5 V with a central EDOT ring (5 VE), have been synthesized via Pd-catalyzed cross-coupling reactions in high yields (66-89 %). Crystal structures of 4 V, 5 B, bithiophene 2 V, and five thiophene-derived intermediates are reported. Chromophores 4 V, 5 V, 5 B and 5 VE have photoluminescence quantum yields of 0.26-0.29, which are higher than those of the shorter analogues 1 V-3 V (0.01-0.20), and short fluorescence lifetimes (0.50-1.05 ns). Two-photon absorption (TPA) spectra have been measured for 2 V-5 V, 5 B and 5 VE in the range 750-920 nm. The measured TPA cross-sections for the series 2 V-5 V increase steadily with length up to a maximum of 1930 GM. We compare the TPA properties of 2 V-5 V with the related compounds 5 B and 5 VE, giving insight into the structure-property relationship for this class of chromophore. DFT and TD-DFT results, including calculated TPA spectra, complement the experimental findings and contribute to their interpretation. A comparison to other related thiophene and dimesitylboryl compounds indicates that our design strategy is promising for the synthesis of efficient dyes for two-photon-excited fluorescence applications
