description: Any type of non-buoyant material in the ocean is transported horizontally by currents during its sinking journey. This lateral transport can be far from negligible for small sinking velocities. To estimate its magnitude and direction, the material is often modelled as a set of Lagrangian particles advected by current velocities that are obtained from Ocean General Circulation Models (OGCMs). State-of-the-art OGCMs are strongly eddying, similar to the real ocean, providing results with a spatial resolution on the order of 10 km on a daily frequency. While the importance of eddies in OGCMs is well-appreciated in the physical oceanographic community, other marine research communities may not. To demonstrate how much the absence of mesoscale features in low-resolution models influences the Lagrangian particle transport, we simulate the transport of sinking Lagrangian particles using low- and high-resolution global OGCMs, and assess the lateral transport differences resulting from the difference in spatial and temporal model resolution. We find major differences between the transport in the non-eddying OGCM and in the eddying OGCM. Addition of stochastic noise to the particle trajectories in the non-eddying OGCM parameterises the effect of eddies well in some cases. The effect of a coarser temporal resolution (5-daily) is smaller compared to a coarser spatial resolution (0.1$^{\circ}$ versus 1$^{\circ}$ horizontally). We recommend to use sinking Lagrangian particles, representing e.g. marine snow, microplankton or sinking plastic, only with velocity fields from eddying OGCMs, requiring high-resolution models in e.g. paleoceanographic studies. To increase the accessibility of our particle trace simulations, we launch planktondrift.science.uu.nl, an online tool to reconstruct the surface origin of sedimentary particles in a specific location.
The Special Licence Model for Access to More Detailed Microdata
Creators: name: Dennison, Karen
Publisher: name: Zenodo
Year: 2006

description: Access to most microdata supplied by the UK Data Archive (UKDA) only requires user registration. Such data are fully anonymised and certain variables may be suppressed or aggregated to minimise disclosure risk. However, there is a research need for more detailed data, such as more precise geographic and occupation codes. To increase the range of data available for research, whilst continuing to safeguard the confidentiality pledge made to survey respondents, the Office for National Statistics (ONS), UKDA, and ESDS Government have developed a Special Licence (SL) and an associated guide to good practice. A range of more detailed ONS data are now available via this new access initiative. This paper describes the data available, discusses the SL model, and outlines the conditions for access to the more detailed data.

description: We present a sample of 4,132 Mira-like variables (red variables with long periods and high amplitudes) in the Kilodegree Extremely Little Telescope (KELT) survey. Of these, 814 are new detections. We used 2MASS colors to identify candidate asymptotic giant branch (AGB) stars. We tested for photometric variability among the sample and used Lomb-Scargle to determine the periodicity of the variable sample. We selected variables with high amplitudes and strong periodic behavior using a Random Forest classifier. Of the sample of 4,132 Mira-like variables, we estimate that 70% are Miras, and 30% are semi-regular (SR) variables. We also adopt the method of using (W_{RP} - W_{K_s}) vs. (J - K_s) colors (Lebzelter et al. 2018) in distinguishing between O-rich and C-rich Miras and find it to be an improvement over 2MASS colors.

description: Performing a Scherk-Schwarz dimensional reduction of D=11 supergravity on a three-dimensional group manifold we construct five D=8 gauged maximal supergravities whose gauge groups are the three-dimensional (non-)compact subgroups of SL(3,R). These cases include the Salam-Sezgin SO(3) gauged supergravity. We construct the most general half-supersymmetric domain wall solutions to these five gauged supergravities. The generic form is a triple domain wall solution whose truncations lead to double and single domain wall solutions. We find that one of the single domain wall solutions has zero potential but nonzero superpotential. Upon uplifting to 11 dimensions each domain wall becomes a purely gravitational 1/2 BPS solution. The corresponding metric has a 7+4 split with a Minkowski 7-metric and a 4-metric that corresponds to a gravitational instanton. These instantons generalize the SO(3) metric of Belinsky, Gibbons, Page and Pope (which includes the Eguchi-Hanson metric) to the other Bianchi types of class A.

Molluscs as ecological indicators in palaeoanthropological contexts

description: One method of investigating the palaeoecology of a site is to analyse the associated faunal remains. In palaeoanthropology faunal analysis is not uncommon, but on most occasions only a fraction of the overall fauna is analysed, often only large mammals. This discrepancy is addressed in this thesis. Here, the molluscan fauna from a range of sites is analysed from an ecological perspective, and the results compared to the palaeoecological results based on other faunal data, including, when available, small mammals, birds, reptiles, fish and amphibians. The aim of this study is to investigate whether the molluscs add anything to the overall palaeoecological picture of a site. The data are analysed from a palaeoanthropological perspective, with different hominine groups of sites compared from a palaeoecological perspective, based on the molluscan data. At the same time the value of molluscs as palaeoecological indicators is measured against data from other sources, such as other faunal data. The results show that molluscs are capable of adding important new and corroborating data that could be used to test established palaeoecological reconstructions of the past. The data support the idea that open habitats may have played an important role in the evolution of the genus Homo, but they also strongly suggest the presence of permanent water, whether in open or closed habitats.

description: We define a regularization-independent momentum-subtraction scheme for the $CP$-odd three-gluon operator at dimension six. This operator appears in effective field theories for heavy physics beyond the Standard Model, describing the indirect effect of new sources of $CP$-violation at low energies. In a hadronic context, it induces permanent electric dipole moments. The hadronic matrix elements of the three-gluon operator are non-perturbative objects that should ideally be evaluated with lattice QCD. We define a non-perturbative renormalization scheme that can be implemented on the lattice and we compute the scheme transformation to $\overline{\text{MS}}$ at one loop. Our calculation can be used as an interface to future lattice-QCD calculations of the matrix elements of the three-gluon operator, in order to obtain theoretically robust constraints on physics beyond the Standard Model from measurements of the neutron electric dipole moment.

The Nature of Data
Creators: name: Farance, Frank
name: Gillman, Daniel W.
Publisher: name: Zenodo
Year: 2006

description: Traditionally, the term "data" is defined by what data does, not what it is. What is data? Often, books and documents are called information. Are objects information? Do they contain information? Data are often defined in terms of information, vice versa, or in terms of some other undefined concept, such as knowledge. All this leads to much confusion. This paper is an attempt to shed light on these and related issues. Terminology theory is the study of concepts and their representations in special languages. It focuses on the essential characteristics of concepts, and therefore on what a concept is. Applying the theory, we define data in a new way, by defining what data is, by investigating its essential characteristics. This, in turn, provides a way to distinguish between data and information usefully. The role of metadata is clearly defined. Then, a definition of data element is derived. Implications for the Semantic Web are discussed.

description: We have developed a self-aligned, high-yield process to fabricate CPP (current perpendicular to the plane) magnetic sensors of sub 100 nm dimensions. A pinned synthetic antiferromagnet (SAF) is used as the reference layer which minimizes dipole coupling to the free layer and field induced rotation of the reference layer. We find that the critical currents for spin transfer induced magnetization reversal of the free layer vary dramatically with relatively small changes the in-plane magnetic field, in contrast to theoretical predictions based on stability analysis of the Gilbert equations of magnetization dynamics including Slonczewski-type spin-torque terms. The discrepancy is believed due to thermal fluctuations over the time scale of the measurements. Once thermal fluctuations are taken into account, we find good quantitative agreement between our experimental results and numerical simulations.

description: A nontrivial scalar field configuration of vanishing energy-momentum is reported. These matter configurations have no influence on the metric and therefore they are not be "detected" gravitationally. This phenomenon occurs for a time-dependent nonminimally coupled and self-interacting scalar field on the 2+1 (BTZ) black hole geometry. We conclude that such stealth configurations exist for the static 2+1 black hole for any value of the nonminimal coupling parameter $ζ\neq0$ with a fixed self-interaction potential $U_ζ(Φ)$.

Metadata by Design and Fielded Metadata: The Poles of a Space in Which Data Processing Takes Place
Creators: name: Hadorn, Reto
Publisher: name: Zenodo
Year: 2006

description: The approach usually taken when conceptualizing metadata is typically one of 'documentation', which supposes a reference object, e.g., data, and something to be told about it. That documentation is static; it describes data in a specific state, usually as ready for publication. The life-cycle idea introduces a new perspective. Sure, one can still reduce metadata to a report about what happened across the life cycle of the data. But there is also an opportunity to model metadata in a way to support work done to obtain data, process, edit and publish them. The following example will be developed. Because we don't use the integrated tools for handling metadata and data all over the life cycle, consistency between the two levels of information may be broken. We need a metadata model, which supports the comparison of metadata drawn from more than one source, e.g., the questionnaire, treated as 'metadata by design', and information extracted from a semi-documented data file, an SPSS data file for example, which stands as the 'fielded metadata'.

description: Musculoskeletal models of the lumbar spine have been developed with varying levels of detail for a wide range of clinical applications. Providing consistency is ensured throughout the modelling approach, these models can be combined with other computational models and be used in predictive modelling studies to investigate bone health deterioration and the associated fracture risk. To provide precise physiological loading conditions for such predictive modelling studies, a new full-body musculoskeletal model including a detailed and consistent representation of the lower limbs and the lumbar spine was developed. The model was assessed against in vivo measurements from the literature for a range of spine movements representative of daily living activities. Comparison between model estimations and electromyography recordings was also made for a range of lifting tasks. This new musculoskeletal model will provide a comprehensive physiological mechanical environment for future predictive finite element modelling studies on bone structural adaptation.

description: The thermalization process of the holographic entanglement entropy (HEE) of an annular domain is investigated over the Vaidya-AdS geometry. We numerically determine the Hubeny-Rangamani-Takayanagi (HRT) surface which may be a hemi-torus or two disks, depending on the ratio of the inner radius to the outer radius of the annulus. More importantly, for some fixed ratio of two radii, it undergoes a phase transition or double phase transitions from a hemi-torus configuration to a two-disk configuration, or vice versa, during the thermalization. The occurrence of various phase transitions is determined by the ratio of two radii of the annulus. The rate of entanglement growth is also investigated during the thermal quench. The local maximal rate of entanglement growth occurs in the region with double phase transitions. Finally, if the quench process is fairly slow which may be controlled by the thickness of null shell, the region with double phase transitions vanishes.

description: Flexible debris-flow nets were developed in the frame of a three-year PhD thesis by Wendeler in 2008. Since then, they have been used all over the world for debris-flow protection or slope/riverbed stabilization. Some of these installed flexible debris-flow nets have already been filled a couple of times and verified the developed load model. Nevertheless, depending on soil properties, most problems with debris-flow nets appear to be related to construction, such as channel flank erosion, which exposes anchors, or undermines supporting foundations. Both cases lead to instability of the entire system and to increased maintenance costs and should therefore be avoided. In this contribution, we present a service ability method for scour and erosion issues on flexible debris- flow nets. In this context, “service ability method” means a design tool that should help to suggest construction possibilities to avoid erosion problems along the barrier in order to guarantee a lifetime of more than 25 years. The results are based on an analysis of existing barriers to determine occurring scour and erosion problems. Hence, an approach to calculate scour and erosion length and depth respectively around the barrier construction is developed. To validate this approach, a debris-flow simulation with the software RAMMS, or equivalent software, is used. In terms of economic efficiency, different construction measures for riverbed and flank stabilization are analyzed and implemented into the service ability. This tool will help designers and planning engineers to design and calculate their debris-flow protection system in a more economic and safe way. Further, maintenance costs will be minimized and a longer lifetime of the entire barrier system, including the anchors as the most cost-intensive parts, can be provided. Since the project is still ongoing, the final design tool with its equations cannot yet be discussed in detail in the following paper.

description: We show that the icosahedral packings of protein capsomeres proposed by Caspar and Klug for spherical viruses become unstable to faceting for sufficiently large virus size, in analogy with the buckling instability of disclinations in two-dimensional crystals. Our model, based on the nonlinear physics of thin elastic shells, produces excellent one parameter fits in real space to the full three-dimensional shape of large spherical viruses. The faceted shape depends only on the dimensionless Foppl-von Karman number γ=YR^2/κ, where Y is the two-dimensional Young's modulus of the protein shell, κis its bending rigidity and R is the mean virus radius. The shape can be parameterized more quantitatively in terms of a spherical harmonic expansion. We also investigate elastic shell theory for extremely large γ, 10^3 < γ< 10^8, and find results applicable to icosahedral shapes of large vesicles studied with freeze fracture and electron microscopy.

Constructing Gravitational Dimensions

description: It would be extremely useful to know whether a particular low energy effective theory might have come from a compactification of a higher dimensional space. Here, this problem is approached from the ground up by considering theories with multiple interacting massive gravitons. It is actually very difficult to construct discrete gravitational dimensions which have a local continuum limit. In fact, any model with only nearest neighbor interactions is doomed. If we could find a non-linear extension for the Fierz-Pauli Lagrangian for a graviton of mass mg which does not break down until the scale Lambda_2=(mg Mpl)^(1/2), this could be used to construct a large class of models whose continuum limit is local in the extra dimension. But this is shown to be impossible: a theory with a single graviton must break down by Lambda_3 = (mg^2 Mpl)^(1/3). Next, we look at how the discretization prescribed by the truncation of the KK tower of an honest extra diemsinon rasies the scale of strong coupling. It dictates an intricate set of interactions among various fields which conspire to soften the strongest scattering amplitudes and allow for a local continuum limit. A number of canditate symmetries associated with locality in the discretized dimension are also discussed.

We see that the complexity of the region of influence of an isolated non-saddle set $K$ depends on the way in which $K$ sits on the phase space at the cohomological level. We construct flows in surfaces having isolated non-saddle sets with a prescribed structure for its region of influence. We also study parametrized families of smooth flows and continuations of non-saddle sets.

Mine Your Data: Contrasting Data Mining Approaches to Numeric and Textual Data Sources
Creators: name: Corti, Louise

Publisher: name: Zenodo
Year: 2006

description: Data mining can be defined as exploration and analysis of large quantities of data in order to discover meaningful patterns and rules. For numeric data the process of this discovery is either directed or non-directed based upon whether there is a fact that we wish to explain through models of explanatory variables, or there is a search for patterns that can prove useful. Text mining is a variation on the field of data mining. It is the discovery by computer of new, previously unknown information, by automatically extracting and linking information from different textual sources. In both methods, automated processes help put together information to uncover new meanings or suggest new hypotheses to be explored further, typically by more conventional means of research. But what are the pros and cons of these methods and how does traditional social science data fit in? This joint paper will elaborate on the typologies of data and text mining, and provide examples and typical models that are relevant to social science and business data. The applicability for Data and Computational Grid applications (e-science) will also be highlighted.
The Angular Momentum Distribution of Gas and Dark Matter in Galactic Halos

Year: 2004

description: (Abridged) We report results of a series of non radiative N-body/SPH simulations in a LCDM cosmology. We find that the spin of the baryonic component is on average larger than that of the dark matter (DM) component and we find this effect to be more pronounced at lower redshifts. A significant fraction f of gas has negative angular momentum and this fraction is found to increase with redshift. We describe a toy model in which the tangential velocities of particles are smeared by Gaussian random motions. This model is successful in explaining some of the angular momentum properties. We compare and contrast various techniques to determine the angular momentum distributions (AMDs). We show that broadening of velocity dispersions is unsuitable for making comparisons between gas and DM. We smooth the angular momentum of the particles over a fixed number of neighbors. We find that an analytical function based on gamma distribution can be used to describe a wide variety of profiles, with just one parameter α. The distribution of the shape parameter $α$ for both gas and DM follows roughly a log-normal distribution. The mean and standard deviation of log(α) for gas is -0.04 and 0.11 respectively. About 90-95% of halos have α<1.3, while exponential disks in NFW halos would require 1.3=1.09 \pm 0.2. α_Gas is also biased towards slightly higher values compared to α_DM.

description: Computational notebooks offer researchers, practitioners, students, and educators the ability to interactively conduct analytics and disseminate reproducible workflows that weave together code, visuals, and narratives. This article explores the potential of computational notebooks in urban analytics and planning, demonstrating their utility through a case study of OSMnx and its tutorials repository. OSMnx is a Python package for working with OpenStreetMap data and modeling, analyzing, and visualizing street networks anywhere in the world. Its official demos and tutorials are distributed as open-source Jupyter notebooks on GitHub. This article showcases this resource by documenting the repository and demonstrating OSMnx interactively through a synoptic tutorial adapted from the repository. It illustrates how to download urban data and model street networks for various study sites, compute network indicators, visualize street centrality, calculate routes, and work with other spatial data such as building footprints and points of interest. Computational notebooks help introduce methods to new users and help researchers reach broader audiences interested in learning from, adapting, and remixing their work. Due to their utility and versatility, the ongoing adoption of computational notebooks in urban planning, analytics, and related geocomputation disciplines should continue into the future.

description: This paper explores the benefits of maker centered education (MCE) and how it can be used in Home Economics (HE) Clothing, Textile and Fashion (CT&F) classes. I begin with a literature review on maker education; outlining a cultural trend called the Maker Movement (MM), the history of making, what makes a ‘maker’ and makerspaces. I then present the connections of making to educational theory and pedagogy, discuss the potential of making in education- specifically HE education. In my own practice, I implemented a maker project and I share my experiences of guiding my students to make something they choose. In this paper I share my explorations using maker education using a narrative, self study action research format of plan, act, observe and reflect. I discuss what I learned in incorporating MCE projects in my home economics teaching.

The superfluid- Mott-insulator phase transition condition is determined by the energy-band structure with an obvious interpretation of the transition mechanism. Moreover the superfluid phase is explained explicitly from the energy spectrum derived in terms of Bogliubov approach.

description: Biogasanlagenbetreiber stehen angesichts des zwischenzeitlichen Preishochs auf den Agrarmärkten und des mit dem EEG 2012 für neue Anlagen eingeführten „Maisdeckels“ zunehmend vor der Herausforderung, ihre Anlagen wirtschaftlich und im Einklang mit den rechtlichen Rahmenbedingungen zu betreiben. Vor diesem Hintergrund wurde die Suche nach alternativen Gärsubstraten zum Mais intensiviert. Diese Entwicklung sowie die zunehmende Problematik der Nährstoffüberschüsse in viehreichen Regionen haben dazu geführt, dass verstärkt Güllefeststoffe als Gärsubstrat in Betracht gezogen werden. Es ist bislang aber wenig bekannt, wie die Absicht von Biogasanlagenbetreibern zur Nutzung von Güllefeststoffen als Gärsubstrat tatsächlich ausgeprägt ist. Um diese Forschungslücke zu schließen, werden in der vorliegenden Studie auf der Grundlage einer Befragung von Anlagenbetreibern mögliche Einflussfaktoren auf die Nutzung von Güllefeststoffen als Gärsubstrat identifiziert. Der Akzeptanzanalyse liegt dabei ein Modell zugrunde, das sich an das Technology Acceptance Model 2 von VENKATESH und DAVIS (2000) anlehnt. Die Auswertung erfolgt mittels der Partial-Least-Squares-Methode (PLS). Die Ergebnisse zeigen, dass das Interesse an Güllefeststoffen seitens der Biogasanlagenbetreiber zwar grundsätzlich vorhanden ist, aber nur wenige Anlagenbetreiber bereit sind, diese auch wirklich einzusetzen. Die Nutzungsabsicht von Güllefeststoffen konnte durch das Modell zu 53 %, das Nutzungsverhalten zu 68 % erklärt werden. Wichtige signifikante Einflussfaktoren sind neben den Kosten vor allem die rechtlichen Rahmenbedingungen, die Risikoeinstellung der Anlagenbetreiber sowie ihre Aufgeschlossenheit gegenüber Innovationen.
Signatures of valence fluctuations in CeCu2Si2 under high pressure

description: Simultaneous resistivity and a.c.-specific heat measurements have been performed under pressure on single crystalline CeCu2Si2 to over 6 GPa in a hydrostatic helium pressure medium. A series of anomalies were observed around the pressure coinciding with a maximum in the superconducting critical temperature, $T_c^{max}$. These anomalies can be linked with an abrupt change of the Ce valence, and suggest a second quantum critical point at a pressure $P_v \simeq 4.5$ GPa, where critical valence fluctuations provide the superconducting pairing mechanism, as opposed to spin fluctuations at ambient pressure. Such a valence instability, and associated superconductivity, is predicted by an extended Anderson lattice model with Coulomb repulsion between the conduction and f-electrons. We explain the T-linear resistivity found at $P_v$ in this picture, while other anomalies found around $P_v$ can be qualitatively understood using the same model.

description: NiO is a prototypical antiferromagnet with a characteristic resonance frequency in the THz range. From atomistic spin dynamics simulations that take into account the crystallographic structure of NiO, and in particular a magnetic anisotropy respecting its symmetry, we describe antiferromagnetic switching at THz frequency by a spin transfer torque mechanism. Sub-picosecond S-state switching between the six allowed stable spin directions is found for reasonably achievable spin currents, like those generated by laser induced ultrafast demagnetization. A simple procedure for picosecond writing of a six-state memory is described, thus opening the possibility to speed up current logic of electronic devices by several orders of magnitude.

description: We present a regular class of exact black hole solutions of Einstein equations coupled with a nonlinear electrodynamics source. For weak fields the nonlinear electrodynamics becomes the Maxwell theory, and asymptotically the solutions behave as the Reissner-Nordström one. The class is endowed with four parameters, which can be thought of as the mass $m$, charge $q$, and a sort of dipole and quadrupole moments $α$ and $β$, respectively. For $α\geq 3$, $β\geq 4$, and $|q| \leq 2 s_c m$ the corresponding solutions are regular charged black holes. For $α=3$, they also satisfy the weak energy condition. For $α=β=0$ we recover the Reissner-Nordström singular solution and for $α=3$, $β=4$ the family includes a previous regular black hole reported by the authors.

description: The accuracy of existent closed-form micromechanical models to predict the five independent elastic constants of unidirectional fiber reinforced composites is assessed. A finite element model is developed to serve as a reference, properly benchmarked against other numerical models and published experimental data, and then used as a baseline for comparison. The detailed numerical analysis of the existent micromechanical models using a formal statistical metric for error quantification allows a quantitative assessment of these models, providing recommendations for the most suited model(s) for each material constant.

description: Im Rahmen einer hedonischen Preisanalyse wird untersucht, wie Qualitätsmerkmale von Wein das Niveau der Weinpreise beeinflussen. Mit Daten der DLG-Bundesweinprämierung wird der Frage nachgegangen, inwieweit Qualitätsauszeichnungen zu höheren Weinpreisen führen. Die Ergebnisse der empirischen Analyse zeigen signifikante Preisaufschläge für die DLG-Prämierungen Silber, Gold und Gold Extra. Durch die erfolgreiche Teilnahme an der Bundesweinprämierung bildet sich folglich ein Marktgleichgewicht mit einer höheren marginalen Zahlungsbereitschaft der Konsumenten. Bei einer erfolgreichen Teilnahme an der Bundesweinprämierung besteht für Produzenten die Möglichkeit, höhere Nettopreise zu erzielen. Entscheidend ist dabei die Vermittlung der Qualität im Kaufentscheidungsprozess. Dem langfristigen Aufbau von Reputation kommt eine größere Bedeutung zu, als der Signalisierung der Qualität durch das Anbringen der Auszeichnungen auf den Weinflaschen. Dies zeigt der ermittelte Preisaufschlag für die Prämierungserfolge vergangener Jahre. Die Analyse zeigt weiter, dass die Charakteristika Qualitätsstufe, Herkunftsregion, Rebsorte und Weinart wichtige Determinanten der Weinpreise sind, da sie die Grenzkosten der Anbieter und/oder die Verbraucherpräferenzen beeinflussen.
